DETAILED DESCRIPTION

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

The outdoor unit 100 according to an embodiment of the present application is described below with reference to FIGS. 1 to 32 .

As shown in FIGS. 2-6 , the outdoor unit 100 according to some embodiments of the present application includes: an outdoor casing 10 , an outdoor heat exchanger 112 , an outdoor fan 111 , a compressor assembly 20 , and a water heat exchange assembly 40 .

The outdoor housing 10 has a fan chamber 11, a compressor chamber 12, and a water channel chamber 13 arranged in the left-right direction. An outdoor air inlet 101 and an outdoor air outlet 102 are formed on the outdoor housing 10, and the outdoor air inlet 101 and the outdoor air outlet 102 are both formed on the outdoor housing at the periphery of the fan chamber 11. For example, the outdoor air outlet 101 is formed on the front side wall of the outdoor housing 10, and the outdoor air inlet 101 is formed on the rear side wall and the left side wall of the outdoor housing 10.

It should be noted that the air outlet side of the outdoor unit 100 is defined as the front side.

The outdoor heat exchanger 112 and the outdoor fan 111 are arranged in the fan chamber 11. The compressor assembly 20 is arranged in the compressor chamber 12 and includes a compressor 21. The outdoor fan 111 is used to drive outdoor air from the outdoor air inlet 101 into the outdoor housing 10, and exchange heat with the outdoor heat exchanger 112, and the air after heat exchange is discharged through the outdoor air outlet 102. The compressor assembly 20 is arranged in the outdoor housing 10, and the compressor assembly 20 can play a role in compressing and driving the refrigerant in the refrigerant circuit.

The water heat exchange assembly 40 includes a water heat exchanger 51 and a water pump 53. The water heat exchanger 51 has a water flow path and a refrigerant flow path for mutual heat exchange. The water pump 53 is used to drive the water flow in the water flow path, and the compressor assembly 20 is used to drive the refrigerant flow in the refrigerant flow path. The water flow path of the water heat exchanger 51 can be connected to the water pump 53, and the water flow can flow into the water heat exchanger 51 and out of the water heat exchanger 51 under the drive of the water pump 53. The refrigerant flow path of the water heat exchanger 51 can be connected to the compressor assembly 20, and the refrigerant in the refrigerant flow path can exchange heat with the water flow in the water flow path, thereby realizing the heating and cooling functions of the water heat exchanger 51 on the water flow. The water heat exchange assembly 40 can adjust the temperature of the water flow passing through, thereby realizing the heating and cooling functions of the whole machine on the water flow. The water flow flowing out of the water heat exchanger 51 can be transported to the room to adjust the temperature of the indoor domestic water or the indoor temperature.

At least the water channel heat exchanger 51 and the water pump 53 in the water channel heat exchange assembly 40 are arranged in the water channel cavity 13. For example, the water channel heat exchanger 51 and the water pump 53 in the water channel heat exchange assembly 40 are arranged in the water channel cavity 13, or the water channel heat exchange assembly 40 is entirely arranged in the water channel cavity 13. This arrangement allows the water channel heat exchange assembly 40 and the compressor assembly 20 to be located in different chambers, respectively, which can make the layout of the whole machine more reasonable, and is conducive to improving the overall assembly rate. At the same time, it can facilitate the position distribution of the pipelines and components between the water channel heat exchange assembly 40 and the compressor assembly 20, facilitate the assembly and maintenance of the whole machine, and is conducive to improving the maintenance efficiency of the whole machine.

The first electric control box component is arranged between the fan cavity and the compressor cavity, and the second electric control box component is arranged in the water channel cavity, which can make the layout of the whole machine more reasonable and help improve the overall assembly rate. At the same time, it is convenient to connect and control the first electric control box component 30 and the second electric control box component 50 with other components of the whole machine.

According to the outdoor unit 100 of the embodiment of the present application, by dividing the outdoor machine casing 10 into a fan chamber 11, a compressor chamber 12 and a water circuit chamber 13 along the left and right directions, the compressor assembly 20 and the water circuit heat exchange assembly 40 are respectively located in different chambers, so that the layout of the whole machine can be more reasonable, and the distribution positions of each component are clear and orderly, which is conducive to the installation and disassembly of the whole machine, improves the assembly efficiency of the whole machine, and facilitates the replacement and maintenance of each component; in addition, the first electric control box component 30 is arranged between the fan chamber 11 and the compressor chamber 12, and the second electric control box component 50 is arranged in the water circuit chamber 13, which can make the layout of the whole machine more reasonable, and facilitate the connection and control of the first electric control box component 30 and the second electric control box component 50 with other components of the whole machine.

According to some embodiments of the present application, the power of at least some of the components 322 in the first electric control box component 30 is greater than the power of the components 322 in the second electric control box component 50. The power of at least some of the components 322 in the first electric control box component 30 is greater than the power of the components 322 in the second electric control box component 50. For example, the power of some of the components 322 in the first electric control box component 30 is greater than the power of the components 322 in the second electric control box component 50, or the power of all the components 322 in the first electric control box component 30 is greater than the power of the components 322 in the second electric control box component 50.

When the component 322 is working, the greater the power of the component 322, the more heat is generated. The heat generated by the first electric control box component 30 is much greater than the heat generated by the second electric control box component 50. The overall heat dissipation of the components 322 with large heat generation can be achieved by dissipating the heat of the first electric control box component 30, thereby improving the overall heat dissipation effect of the components 322 and reducing the overall cost.

According to some embodiments of the present application, with reference to FIG. 2 , the first electric control box component 30 is at least used to control the outdoor fan 111 and the compressor 21. For example, the first electric control box component 30 is partially used to control the compressor 21 and the outdoor fan 111 or the first electric control box component 30 is entirely used to control the compressor 21 and the outdoor fan 111. The second electric control box component 50 is used to control the water heat exchange component 40 or to control the water heat exchange component 40 and the refrigerant flow path. For example, the second electric control box component 50 can be used to control the refrigerant flow path, and the second electric control box component 50 can be used to control at least one of the electronic expansion valve and the four-way valve 27 connected to the refrigerant flow path; for another example, the second electric control box component 50 can be used to control the water heat exchange component 40, and the second electric control box component 50 can be used to control the water pump 53 in the water heat exchange component 40.

On the other hand, at least one of the first electric control box component 30 and the second electric control box component 50 can be pulled out in the up-down direction. When the first electric control box component 30 and the second electric control box component 50 need to be installed on the first middle partition 113 and the second middle partition 121 respectively, the gravity of the first electric control box component 30 and the second electric control box component 50 can be used to assemble itself with the whole machine, thereby reducing the difficulty of assembly, improving work efficiency, and reducing costs.

According to some embodiments of the present application, referring to Figures 5 and 28, a second middle partition plate 121 is provided between the compressor chamber 12 and the water circuit chamber 13. The compressor assembly 20 and the water circuit heat exchange assembly 40 are separated by the second middle partition plate 121, which can make the layout of the whole machine more reasonable and facilitate the maintenance and replacement of different components.

A pipe hole 1212 is formed at the lower portion of the second middle partition 121.

The water refrigerant pipe 1213 is suitable for passing through the pipe hole 1212 to run to the water cavity 13, which can shorten the refrigerant flow path between the compressor assembly 20 and the water heat exchanger, thereby reducing the overall length of the water refrigerant pipe 1213 and saving costs; at the same time, it can facilitate the connection between the compressor assembly 20 and the water heat exchanger and improve assembly efficiency.

According to some embodiments of the present application, referring to Figures 2 and 9, a first middle partition plate 113 is provided between the fan chamber 11 and the compressor chamber 12. The fan chamber 11 and the compressor chamber 12 are separated by the first middle partition plate 113, which can make the layout of the whole machine more reasonable and facilitate the maintenance and replacement of different components.

The first electric control box component 30 is arranged on the first middle partition plate 113, and the first electric control box component 30 includes a first electric control box 3, and the first electric control box 3 includes a first electric control box body 31 and a first electric control component 32 arranged in the first electric control box body 31, and the first electric control component 32 includes an electric control board 321 and components 322 arranged on the electric control board 321, and the first electric control box body 31 can accommodate and protect the first electric control component 32.

The two opposite sides of the electric control board 321 in the thickness direction are respectively the first side and the second side. There are multiple components 322, and at least some of the components 322 are arranged on the first side of the electric control board 321. For example, some of the components 322 on the electric control board 321 are arranged on the first side of the electric control board 321, or all of the components 322 on the electric control board 321 are arranged on the first side of the electric control board 321. The first side of the electric control board 321 faces the fan cavity 11.

When the first electric control assembly 32 in the first electric control box 3 is working, the components of the first electric control assembly 32 will generate a lot of heat, resulting in an excessively high temperature in the first electric control box 3. If the overall heat dissipation effect of the first electric control box 3 is poor, it will affect the control effect of the first electric control assembly 32 on other components and cause the components 322 to age and fail. Therefore, the first side of the electric control board 321 faces the fan cavity 11, which makes the distance between the components 322 on the first side of the electric control board 321 and the fan cavity 11 closer. The fan cavity 11 is provided with an outdoor fan 111, and the outdoor fan 111 can use the flow of air to enhance the heat exchange between the outdoor heat exchanger 112 and the air. In the process of the outdoor fan 111 driving the air flow, the first side of the electric control board 321 is directed toward the fan cavity 11, and the air flow in the fan cavity 11 can be used to take away the heat of the components 322 on the first side of the electric control board 321, which is conducive to improving the overall heat dissipation efficiency of the first electric control assembly 32 and extending the service life of the first electric control assembly 32.

According to some embodiments of the present application, at least some of the multiple components 322 are power devices, for example, some of the multiple components 322 are power devices or all of the multiple components 322 are power devices.

Since when the first electric control component 32 is working, the heat generated by the power devices is greater than the heat generated by other components 322. Therefore, at least some of the power devices are located on the first side of the electric control board 321, which can shorten the distance between the power devices and the fan cavity 11, and is conducive to improving the overall heat dissipation efficiency of the first electric control component 32, and ensuring the normal use of the first electric control component 32.

According to some embodiments of the present application, referring to FIG. 2 , the first electric control box component 30 includes a first radiator 4, and a first radiator 4 is provided on a side of the first electric control box 3 adjacent to the fan cavity 11, and at least a portion of the first radiator 4 is located in the fan cavity 11, for example, the first radiator 4 may be partially located in the fan cavity 11 or the first radiator 4 may be entirely located in the fan cavity 11. The first radiator 4 may have a heat dissipation and cooling effect on the first electric control component 32. The heat generated by the first electric control component 32 during operation will be transferred to the first electric control box 3, and the heat will be transferred to the first radiator 4 through the first electric control box 3. The first radiator 4 may dissipate the heat of the first electric control box 3, thereby realizing the heat dissipation and cooling effect of the first radiator 4 on the first electric control component 32.

Since an outdoor fan 111 is provided in the fan cavity 11, the outdoor fan 111 can utilize the flow of air to enhance the heat exchange between the outdoor heat exchanger 112 and the air. The first radiator 4 is provided on a side of the first electric control box 3 adjacent to the fan cavity 11, and at least a portion of the first radiator 4 is located in the fan cavity 11. During the operation of the outdoor fan 111, the air flow in the fan cavity 11 can be utilized to quickly take away the heat of the first radiator 4, thereby improving the overall heat dissipation effect on the first radiator 4, and thus improving the heat dissipation efficiency of the first radiator 4 to the first electric control component 32.

According to some embodiments of the present application, referring to FIG. 7 , a surface of the first radiator 4 facing the fan chamber 11 is formed with a relief slope 43 for avoiding the outdoor fan 111, and the relief slope 43 extends obliquely from top to bottom in a direction away from the outdoor fan 111. The setting of the relief slope 43 can provide a certain safety gap between the first radiator 4 and the outdoor fan 111, prevent the first radiator 4 and the outdoor fan 111 from colliding, and ensure the safety performance of the first radiator 4. At the same time, the heat dissipation and cooling effect of the outdoor fan 111 on the first radiator 4 and the heat dissipation efficiency of the first radiator 4 on the first electric control box 3 can be ensured.

According to some embodiments of the present application, referring to FIG. 7-FIG. 8, the first radiator 4 includes a plurality of first radiator fins 41 arranged at intervals, and the plurality of first radiator fins 41 can be arranged evenly at intervals in the front-to-back direction. The plurality of first radiator fins 41 can increase the heat exchange area of the first radiator 4 and improve the heat dissipation efficiency of the first radiator 4. A first heat dissipation channel 42 extending in the up-down direction is defined between adjacent first radiator fins 41, and the airflow is suitable for flowing through the first heat dissipation channel 42 in the up-down direction. There can be a plurality of first heat dissipation channels 42, and the plurality of first heat dissipation channels 42 can be arranged at intervals in the front-to-back direction. The outdoor fan 111 mainly uses the flow of air to dissipate heat from the surrounding components. When the outdoor fan 111 is working, the airflow can flow through the first heat dissipation channel 42 between adjacent first radiator fins 41. During the flow of the airflow in the first heat dissipation channel 42, heat exchange can be generated with the adjacent first radiator fins 41, so that after the airflow flows out of the first heat dissipation channel 42, the heat of the first radiator fins 41 can be taken away, so as to achieve the heat dissipation and cooling effect of the first radiator 4, thereby making the first radiator 4 have a better heat dissipation effect on the first electric control box 3.

Since the rotation axis of the outdoor fan 111 extends in the forward and backward directions, the first heat dissipation channel 42 extends in the up and down directions, so that the extension direction of the first heat dissipation channel 42 is perpendicular to the extension direction of the rotation axis of the outdoor fan 111. During the rotation of the outdoor fan 111, the airflow can flow along the first heat dissipation channel 42, so that the outdoor fan 111 has a better heat dissipation effect on the first radiator 4.

For example, the outdoor unit may include one of the first air guide cover 1131 and the second air guide cover 1134, or the outdoor unit may include the first air guide cover 1131 and the second air guide cover.

The first air guide 1131 is located at the top of the first radiator 4, and the second air guide cover 1134 is located at the bottom of the first radiator 4. The first air guide cover 1131 and the second air guide cover 1134 are both used to guide the airflow in the compressor cavity 12 to the first radiator 4. The first air guide cover 1131 can guide the airflow at the top of the first radiator 4, and the second air guide cover 1134 can guide the airflow at the bottom of the first radiator 4. When the outdoor fan 111 is working, the air pressure in the fan cavity 11 is lower than the air pressure in the compressor cavity 12, so that the air in the compressor cavity 12 flows to the fan cavity 11. A part of the air in the compressor cavity can flow to the top of the first radiator 4 along the first air guide cover 1131, and flow into the fan cavity 12 along the surface of the first radiator 4; another part of the air in the compressor cavity can flow to the bottom of the first radiator 4 along the second air guide cover 1134, and flow into the fan cavity 12 along the surface of the first radiator 4. When the airflow flows along the surface of the first radiator 4 , it will take away the heat of the first radiator 4 , thus achieving a better heat dissipation and cooling effect on the first radiator 4 .

According to some embodiments of the present application, referring to Figures 2-3 and 5-6, a first air guide cavity 1132 is jointly defined between the first air guide cover 1131 and the first radiator 4, or the first air guide cover 1131, the first radiator 4 and the first middle partition plate 113 jointly define the first air guide cavity 1132, and the first air guide cavity 1132 connects the compressor cavity 12 and the first heat dissipation channel 42.

A first air guide port 1138 is formed on one side of the first air guide cover 1131 facing the compressor chamber 12, and the airflow in the compressor chamber 12 is suitable for flowing into the first air guide port 1138 into the first air guide chamber 1132 and flowing downward through the first heat dissipation channel 42. When the outdoor fan 111 is working, the outdoor fan 111 will drive the air in the fan chamber 11 to flow to the outside, so that the air pressure in the fan chamber 11 is lower than the air pressure in the compressor chamber 12. Since the compressor chamber 12 is connected to the upper part of the first heat dissipation channel 42 through the first air guide chamber 1132, and the first heat dissipation channel 42 is connected to the fan chamber 11. Therefore, under the action of the air pressure difference between the fan chamber 11 and the compressor chamber 12, the air in the compressor chamber 12 can flow into the first air guide chamber 1132 through the first air guide port 1138 on the first air guide cover 1131, and the air in the first air guide chamber 1132 can flow downward along the first heat dissipation channel 42, and finally flow out from the first heat dissipation channel 42 and enter the fan chamber 11. When the airflow flows through the first heat dissipation channel 42, it can exchange heat with the adjacent first heat sink 41. When flowing out of the first heat dissipation channel 42, the airflow can take away the heat of the first heat sink 41, thereby achieving the heat dissipation effect on the first radiator 4, and further improving the heat dissipation effect of the first radiator 4 on the first electric control box 3.

According to some embodiments of the present application, referring to Fig. 11, the surface of the first air guide cover 1131 facing the fan cavity 11 is the first surface 1131a, and the portion of the first surface 1131a adjacent to the first radiator 4 is flush with the surface of the first radiator 4 facing the fan cavity 11. This arrangement can ensure that the airflow in the first air guide cavity 1132 can flow into the first heat dissipation channel 42 along the first air guide cover 1131 under the action of the first air guide cover 1131, thereby better improving the heat dissipation effect of the outdoor fan 111 on the first radiator 4.

According to some embodiments of the present application, referring to FIG. 11-FIG. 12, the upper end of the first radiator 4 is located in the first air guide cover 1131. With this arrangement, the airflow in the first air guide cavity 1132 can flow along the first heat dissipation channel 42 of the first radiator 4 under the action of the first air guide cover 1131, so that more airflow flows in the first heat dissipation channel 42, thereby increasing the heat exchange between the airflow and the adjacent first heat sink 41, and achieving a better overall heat dissipation effect on the first radiator 4. For example, the distance in the horizontal direction between the portion of the first surface 1131a of the first air guide cover 1131 adjacent to the first radiator 4 and the surface of the first radiator 4 facing the fan cavity 11 can be 0-5mm, which can better improve the heat dissipation effect of the outdoor fan 111 on the first radiator 4.

According to some embodiments of the present application, referring to FIGS. 2-3 and 5-6, the second air guide hood 1134 and the first radiator 4 define a second air guide cavity 1135 together, or the second air guide hood 1134, the first radiator 4 and the first middle partition plate 113 define a second air guide cavity 1135 together, and the second air guide cavity 1135 connects the compressor cavity 12 and the first heat dissipation channel 42. The second air guide hood 1134 can guide the airflow at the bottom of the first radiator 4. When the outdoor fan 111 is working, the air pressure in the fan cavity 11 is lower than the air pressure in the compressor cavity 12. Since the compressor cavity 12 is connected to the first heat dissipation channel 42 through the second air guide cavity 1135, and the first heat dissipation channel 42 is connected to the fan cavity 11, the air in the compressor cavity 12 can flow into the fan cavity 11 after passing through the first air guide cavity 1132 and the first heat dissipation channel 42 in sequence under the action of the air pressure difference between the fan cavity 11 and the compressor cavity 12. When the airflow flows through the first heat dissipation channel 42, heat exchange can occur with the adjacent first heat sink 41. When the airflow flows out of the first heat dissipation channel 42, the airflow can take away the heat of the first heat sink 41, thereby achieving a heat dissipation effect on the first radiator 4, thereby improving the heat dissipation effect of the first radiator 4 on the first electric control box 3.

According to some embodiments of the present application, referring to Fig. 11, the surface of the second air guide cover 1134 facing the fan cavity 11 is the second surface 1134a, and the portion of the second surface 1134a adjacent to the first radiator 4 is flush with the surface of the first radiator 4 facing the fan cavity 11. This arrangement can ensure that the airflow in the second air guide cavity 1135 can flow into the first heat dissipation channel 42 along the second air guide cover 1134 under the action of the second air guide cover 1134, thereby better improving the heat dissipation effect of the outdoor fan 111 on the first radiator 4.

According to some embodiments of the present application, referring to FIG. 11-FIG. 12, the lower end of the first radiator 4 is located in the second air guide cover 1134. The airflow in the cavity 1135 can flow along the first heat dissipation channel 42 of the first radiator 4 under the action of the second air guide 1134, so that more airflow flows in the first heat dissipation channel 42, thereby increasing the heat exchange between the airflow and the adjacent first heat sink 41, and achieving a better overall heat dissipation effect on the first radiator 4. For example, the distance in the horizontal direction between the portion of the second surface 1134a of the second air guide 1134 adjacent to the first radiator 4 and the surface of the first radiator 4 facing the fan cavity 11 can be 0-5mm, which can better improve the heat dissipation effect of the outdoor fan 111 on the first radiator 4.

According to some embodiments of the present application, referring to FIG. 12 , the second air guide cavity 1135 is connected to the compressor cavity 12 through the second air guide port 1139, and the airflow in the compressor cavity 12 is suitable for flowing into the second air guide cavity 1135 through the second air guide port 1139 and flowing upward through the first heat dissipation channel 42. When the outdoor fan 111 is working, the outdoor fan 111 will drive the air in the fan cavity 11 to flow to the outside, so that the air pressure in the fan cavity 11 is lower than the air pressure in the compressor cavity 12. Since the compressor cavity 12 is connected to the lower part of the first heat dissipation channel 42 through the second air guide cavity 1135, and the first heat dissipation channel 42 is connected to the fan cavity 11. Therefore, under the action of the air pressure difference between the fan cavity 11 and the compressor cavity 12, the air in the compressor cavity 12 can flow into the second air guide cavity 1135 through the second air guide port 1139, and the air in the second air guide cavity 1135 can flow upward along the first heat dissipation channel 42, and finally flow out from the first heat dissipation channel 42 and enter the fan cavity 11. When the airflow flows through the first heat dissipation channel 42, it can exchange heat with the adjacent first heat sink 41. When flowing out of the first heat dissipation channel 42, the airflow can take away the heat of the first heat sink 41, thereby achieving the heat dissipation effect on the first radiator 4, and further improving the heat dissipation effect of the first radiator 4 on the first electric control box 3.

According to some embodiments of the present application, referring to FIG. 3-FIG. 4, the outer cover of the compressor assembly 20 is provided with a soundproof cover 25, which can absorb and insulate the compressor assembly 20, and can effectively reduce the overall noise of the outdoor unit 100. A soundproof cavity 254 for accommodating the compressor assembly 20 is defined between the soundproof cover 25 and the chassis 16 of the outdoor housing 10, and the second air guide 1139 is located outside the soundproof cover 25, which can prevent the noise of the compressor assembly 20 in the soundproof cavity 254 from being transmitted from the second air guide 1139, thereby ensuring the overall noise reduction effect on the compressor assembly 20. At the same time, the second air guide 1139 is arranged outside the soundproof cover 25, which can also ensure that the air in the compressor cavity 12 can quickly flow to the second air guide cavity 1135, so that the ventilation volume in the second air guide cavity 1135 is large, which is conducive to the heat dissipation of the first radiator 4 by the outdoor fan 111.

According to some embodiments of the present application, referring to FIG. 3 , one side of the second air guide cavity 1135 facing the compressor cavity 12 is opened to form a second air guide port 1139. This arrangement can facilitate the air in the compressor cavity 12 to flow into the second air guide cavity 1135 through the second air guide port 1139, thereby ensuring the ventilation volume of the second air guide cavity 1135 and improving the overall heat dissipation effect on the first radiator 4 and the first electric control box component 30. When the outdoor fan 111 is working, the air in the compressor cavity 12 can flow into the second air guide cavity 1135 from the second air guide port 1139 under the action of the air pressure difference between the fan cavity 11 and the compressor cavity 12, and flow upward along the first heat dissipation channel 42 under the action of the second air guide cover 1134, and finally flow out from the first heat dissipation channel 42 and enter the fan cavity 11, thereby achieving the heat dissipation effect on the first radiator 4.

According to some embodiments of the present application, referring to FIG8-FIG9 and FIG12, the first electric control box component 30 further includes a second radiator 44, and a second radiator 44 is provided on a side of the first electric control box 3 adjacent to the compressor cavity 12, and at least a portion of the second radiator 44 is located in the compressor cavity 12. For example, a portion of the second radiator 44 is located in the compressor cavity 12, or the entire second radiator 44 is located in the compressor cavity 12. The second radiator 44 can dissipate heat for the first electric control box 3, improve the overall cooling effect on the first electric control box 3, and thus better ensure the performance of the components 322 inside the first electric control box 3.

The second radiator 44 includes a plurality of second radiator fins 441 arranged at intervals, and the plurality of second radiator fins 441 can be arranged evenly at intervals in the front-to-back direction. The plurality of second radiator fins 441 can increase the heat exchange area of the second radiator 44 and improve the heat dissipation efficiency of the second radiator 44 to the first electric control box 3. A second heat dissipation channel 442 extending in the up-down direction is defined between adjacent second radiator fins 441. There can be a plurality of second heat dissipation channels 442, and the plurality of second heat dissipation channels 442 can be arranged at intervals in the front-to-back direction. The airflow in the compressor cavity 12 is suitable for flowing through the second heat dissipation channel 442 in the up-down direction and flowing to the first heat dissipation channel 42. In the process of the airflow flowing in the second heat dissipation channel 442, heat exchange can be generated with the adjacent second heat dissipation fins 441, so that after the airflow flows out of the second heat dissipation channel 442, the heat of the second heat dissipation fins 441 can be taken away, so as to achieve the heat dissipation and cooling effect of the second radiator 44, thereby making the second radiator 44 have a better heat dissipation effect on the first electric control box 3.

When the outdoor fan 111 is working, the air pressure in the fan chamber 11 will be lower than the air pressure in the compressor chamber 12, and the airflow in the compressor chamber 12 will flow to the fan chamber 11 under the action of the air pressure difference. When the airflow in the compressor chamber 12 flows to the vicinity of the second radiator 44, a part of the airflow will flow upward along the second heat dissipation channel 442, then flow into the first heat dissipation channel 42 from the upper part of the first electric control box 3, and flow downward along the first heat dissipation channel 42, and finally flow out of the first heat dissipation channel 42 from the middle part of the first heat dissipation channel 42 in the vertical direction and enter the fan chamber 11. Another part of the airflow will flow downward along the second heat dissipation channel 442, then flow into the first heat dissipation channel 42 from the lower part of the first electric control box 3, and flow upward along the first heat dissipation channel 42, and finally flow out of the first heat dissipation channel 42 from the middle part of the first heat dissipation channel 42 in the vertical direction and enter the fan chamber 11. When the airflow flows through the second heat dissipation channel 442 and the first heat dissipation channel 42 in sequence, it can exchange heat with the adjacent second heat sink 441 and the first heat sink 41. Finally, when flowing out of the first heat dissipation channel 42, the airflow can take away the heat, thereby achieving the heat dissipation effect on the first radiator 4 and the second radiator 44, thereby improving the overall heat dissipation efficiency of the first electronic control box 3 and ensuring the normal use of the first electronic control component 30.

According to some embodiments of the present application, referring to FIG. 8 , the height of the first heat sink 41 in the left-right direction is greater than the height of the second heat sink 441 in the left-right direction. With such a configuration, the heat exchange area between the first heat sink 41 and the airflow in the first heat dissipation channel 42 can be greater than the heat exchange area between the second heat sink 441 and the airflow in the second heat dissipation channel 442, so that in the same time, the heat exchange amount of the first heat sink 4 is greater than the heat exchange amount of the second heat sink 44, so that the heat dissipation efficiency of the first heat sink 4 is higher than that of the second heat sink 44. In addition, the first heat sink 4 is located in the fan cavity 11, and the air flow speed in the fan cavity 11 is faster. Compared with the second heat sink 44, the heat dissipation effect of the whole machine on the first heat sink 4 is better, so that the heat dissipation and cooling effect of the whole machine on the components 322 on the side of the electric control board 321 facing the first heat sink 4 is better.

The water flow can enter the electric heater 52 from the second water inlet 521 of the electric heater 52, and after the water flow is heated inside the electric heater 52, it can flow out from the second water outlet 522. Since the second water inlet 521 is connected to the first water outlet 514, the water flow flowing out from the first water outlet 514 of the water circuit heat exchanger 51 can enter the electric heater 52 through the second water inlet 521, and finally the water flow flows out through the second water outlet 522.

When the whole machine needs to heat the water flow, the refrigerant in the refrigerant flow path exchanges heat with the water flow in the water flow path and then flows out of the water flow heat exchanger 51. The external water flow can flow into the water flow heat exchanger 51 through the first water inlet 513, and the water flow can flow out of the water flow heat exchanger 51 from the first water outlet 514 after exchanging heat with the refrigerant flow path of the water flow heat exchanger 51.

External water can flow into the water heat exchange assembly 40 through the water inlet pipe 54, and the water in the water inlet pipe 54 flows into the water heat exchanger 51 through the first water inlet 513. After heat exchange with the refrigerant flow path in the water heat exchanger 51, the water can flow out of the water heat exchanger 51 from the first water outlet 514 and enter the connecting pipe 56. Then the water flow in the connecting pipe 56 can flow into the electric heater 52 through the second water inlet 521. After the water flow is heated inside the electric heater 52, it can flow out of the electric heater 52 from the second water outlet 522, and finally flow out of the water path heat exchange component 40 through the outlet pipe 55 and enter the room.

The connecting pipe 56, the water inlet pipe 54 and the water outlet pipe 55 are all located on the same side of the water heat exchanger 51 and the electric heater 52. The pipelines of the assembly 40 are all located on the same side of the water heat exchanger 51 and the electric heater 52, which facilitates the connection of the water heat exchanger 51 and the electric heater 52 with other components and improves the overall installation efficiency. At the same time, it is conducive to the rational use of the overall space and makes the overall structure more compact. In addition, the connection pipelines of the water heat exchange assembly 40 can be distributed in a more concentrated position, which can facilitate the installation and disassembly of the water heat exchange assembly 40 of the whole machine, as well as the replacement and maintenance of the connection pipelines, thereby improving the maintenance efficiency.

According to some embodiments of the present application, referring to FIG. 17 , the outdoor housing 10 has a fan chamber 11 and a compressor chamber 12, and a first intermediate partition 113 is provided between the fan chamber 11 and the compressor chamber 12. The first intermediate partition 113 can separate the fan chamber 11 and the compressor chamber 12, thereby making the layout of the whole machine more reasonable and facilitating the maintenance and replacement of different components. The water heat exchange assembly 40 also includes an expansion tank 59, which can be used to balance the water volume and pressure in the water flow path of the water heat exchange assembly 40.

A mounting opening 113a is formed at the lower portion of the first middle partition 113, and the expansion tank 59 is installed at the mounting opening 113a. Part of the expansion tank 59 is located in the fan cavity 11, and the other part of the expansion tank 59 is located in the compressor cavity 12. This can achieve full utilization of the space of the fan cavity 11 and the compressor cavity 12, making the overall structure more compact and improving the utilization rate of the overall space.

According to some embodiments of the present application, referring to FIG. 17 , the expansion tank 59 is located below the outdoor fan 111 , which can make full use of the space between the bottom of the outdoor fan 111 and the outdoor casing 10 , making the overall structure more compact and improving the utilization of the overall space.

According to some embodiments of the present application, referring to FIG. 17 , the minimum distance between the expansion tank 59 and the outer edge of the outdoor fan 111 is greater than 20 mm. If the minimum distance between the expansion tank 59 and the outer edge of the outdoor fan 111 is less than 20 mm, on the one hand, it will cause the expansion tank 59 to collide with the outdoor fan 111 and be damaged. In addition, when the external temperature is low, ice will form on the outer wall of the expansion tank 59, resulting in adhesion between the expansion tank 59 and the outer edge of the outdoor fan 111 due to ice, affecting the normal use of the whole machine. On the other hand, when the outdoor fan 111 is working, the expansion tank 59 will increase the nearby wind resistance and generate noise, which is not conducive to the overall noise reduction effect.

Therefore, the minimum distance between the expansion tank 59 and the outer edge of the outdoor fan 111 is greater than 20 mm, which can avoid the expansion tank 59 from colliding with the outdoor fan 111, and avoid adhesion between the expansion tank 59 and the outer edge of the outdoor fan 111 when the external temperature is low, thereby better ensuring the safety and reliability of the expansion tank 59 and the normal use of the whole machine. At the same time, it can avoid noise in the fan chamber 11 and ensure the overall noise reduction effect.

According to some embodiments of the present application, with reference to FIG. 17 , the minimum distance between the expansion tank 59 and the outer edge of the outdoor fan 111 ranges from 20 mm to 50 mm, which can avoid collision between the expansion tank 59 and the outdoor fan 111, and avoid adhesion between the expansion tank 59 and the outer edge of the outdoor fan 111 when the external temperature is low, thereby better ensuring the safety and reliability of the expansion tank 59 and the normal use of the whole machine; and avoiding noise in the fan cavity 11, ensuring the overall noise reduction effect. At the same time, it can avoid the minimum distance between the expansion tank 59 and the outer edge of the outdoor fan 111 from being too large, thereby ensuring the size of the whole machine and reducing the space occupied by the whole machine. For example, the minimum distance between the expansion tank 59 and the outer edge of the outdoor fan 111 can be 20 mm, 30 mm, 40 mm, 50 mm, etc.

According to some embodiments of the present application, referring to FIG. 17 , the expansion tank 59 is supported on the chassis 16 of the outdoor housing 10. When condensation water appears on the surface of the expansion tank 59, the expansion tank 59 is supported on the chassis 16 of the outdoor housing 10, so that the condensation water can flow directly onto the chassis along the surface of the expansion tank 59, and the condensation water can be prevented from dripping onto other structures and causing damage to other structures, thereby ensuring the performance of the whole machine; and the space between the outer edge of the outdoor fan 111 and the chassis 16 can be fully utilized, making the overall structure more compact and improving the overall space utilization. At the same time, it can also facilitate the overall fixation of the expansion tank 59, and improve the safety and stability of the expansion tank 59 during the overall working process.

According to some embodiments of the present application, the water circuit heat exchange assembly 40 further includes an expansion tank 59, which is located outside the outdoor housing 10 and adjacent to the water circuit cavity 13, so that the whole machine can improve the performance of the expansion tank 59 by increasing its own volume, and avoid the problem of the whole machine size being larger due to the large volume of the expansion tank 59; at the same time, it can facilitate the installation and removal of the expansion tank 59, as well as the replacement and maintenance of the expansion tank 59, thereby improving the overall assembly efficiency. In addition, during the operation of the whole machine, when the amount of water in the expansion tank 59 is small, it is convenient to replenish the amount of water in the expansion tank 59, thereby ensuring the performance of the expansion tank 59.

According to some embodiments of the present application, referring to Figures 14 and 16, the water channel heat exchange assembly 40 includes an electric heater 52, which is disposed in the water channel cavity 13 and is used to heat the water in the water flow path. The electric heater 52 is disposed in the water channel cavity 13, which can facilitate the connection between the electric heater 52 and the water channel heat exchanger 51, making the spatial distribution of the whole machine more reasonable and the structure more compact.

The second electric control box component 50 includes a main electric control box body 61, a sub-electric control box body 62, a main control board 63 and an electric heating control component 64. The main control board 63 is disposed in the main electric control box body 61, and at least a portion of the electric heating control component 64 is disposed in the sub-electric control box body 62. For example, the electric heating control component 64 can be partially disposed in the sub-electric control box body 62, or the electric heating control component 64 can be entirely disposed in the sub-electric control box body 62.

The electric heating control component 64 is used to control the electric heater 52 . For example, the electric heating control component 64 can control the on and off of the electric heater 52 . The electric heating control component 64 can also control the heating power and heating temperature of the electric heater 52 .

The sub-electrical control box body 62 is located outside the main electric control box body 61 and is formed independently of the main electric control box body 61. Since the electric heating control assembly 64 is located in the sub-electrical control box body 62, when the water circuit heat exchange assembly 40 does not include the above-mentioned electric heater 52, the second electric control box component 50 may include the above-mentioned main electric control box body 61 and the main control board 63 but does not include the above-mentioned sub-electrical control box body 62 and the electric heating control assembly 64. When the water circuit heat exchange assembly 40 includes the above-mentioned electric heater 52, the main body of the second electric control box component 50 does not need to be significantly modified or may not be modified, and only the above-mentioned sub-electrical control box body 62 and the electric heating control assembly 64 need to be added on the basis of the electric control box component corresponding to the water circuit heat exchange assembly 40 not including the above-mentioned electric heater 52. In this way, the control part of the second electric control box component 50 for the electric heater 52 can be modularized, and the main electric control box body 61 and the main control board 63 as the main part of the second electric control box component 50 can be used as a common structure. Regardless of whether the electric heater 52 is included, the second electric control box component 50 includes the main electric control box body 61 and the main control board 63 as the common part. When the electric heater 52 needs to be installed in the outdoor unit 100, there is no need to change or significantly change the structure of the main electric control box body 61 and the main control board 63. Only the above-mentioned sub-electric control box body 62 and the electric heating control component 64 need to be added, which can reduce production costs.

Among them, when the electric heating control component 64 is entirely arranged in the sub-electrical control box body 62, the control part of the electric heater 52 can be better modularized, so that the control part of the electric heater 52 forms a module structure independent of the main electric control box body 61, which can further reduce the production cost, make the design of the second electric control box component 50 more flexible, and also facilitate the maintenance and replacement of the electric heating control component 64.

According to some embodiments of the present application, referring to FIG. 16 , the sub-electric control box body 62 is detachably connected to the main electric control box body 61 , which can facilitate the installation and removal of the sub-electric control box body 62 , and the replacement and maintenance of the internal components of the sub-electric control box body 62 .

According to some embodiments of the present application, referring to FIG. 16 , the electric heating control assembly 64 includes an AC contactor 641, which is disposed in the sub-electrical control box body 62. The AC contactor 641 can be used to control the start and stop of the electric heater 52 to ensure the normal use of the electric heater 52. Since the AC contactor 641 is relatively large in size, the AC contactor 641 is disposed in the sub-electrical control box body 62, which can save space in the main electric control box body 61, so that the main electric control box body 61 occupies less space as a whole, thereby saving the cost of the second electric control box component 50. In addition, the AC contactor 641 is disposed in the sub-electrical control box body 62, which can facilitate the installation and removal of the electric heating control assembly 64 as a whole.

According to some embodiments of the present application, referring to FIG. 16 , the electric heating control assembly 64 includes an electric heating thermostat 642 for controlling the heating temperature of the electric heater 52. The electric heating thermostat 642 can be used to control the temperature of the electric heater 52, so as to better achieve the effect of the electric heater 52 assisting the heating of the water circuit heat exchanger 51, and ensure that the heating capacity of the whole machine can meet the use requirements. The electric heating thermostat 642 is arranged in the sub-electric control box body 62 or in the main electric control box body 61. Since the electric heating control assembly 64 includes an AC contactor 641 and an electric heating thermostat 642, and the AC contactor 641 is located in the sub-electric control box body 62. When the electric heating thermostat 642 is arranged in the sub-electric control box body 62, the electric heating control assembly 64 can be completely located in the sub-electric control box body 62, so that the replacement and maintenance of the electric heating control assembly 64 as a whole can be facilitated. When the electric heating thermostat 642 is disposed in the main electric control box body 61 , the space inside the main electric control box body 61 can be fully utilized, thereby improving the space utilization rate of the main electric control box body 61 .

According to some embodiments of the present application, referring to FIG. 6 and FIG. 16 , the sub-electrical control box body 62 is connected to the upper portion of the main electric control box body 61. In some embodiments of the present application, The electric heater 52 is located directly above the water circuit heat exchanger 51, and the electric heating control assembly 64 is located in the sub-electric control box body 62. This arrangement allows the sub-electric control box body 62 and the electric heater 52 to be located above the water circuit heat exchange assembly 40, so that the distance between the sub-electric control box body 62 and the electric heater 52 is shorter, thereby facilitating the connection between the sub-electric control box body 62 and the electric heater 52 and shortening the length of the wiring harness between the sub-electric control box body 62 and the electric heater 52.

According to some embodiments of the present application, referring to FIG. 6 , the sub-electrical control box body 62 is located on a side of the main electric control box body 61 adjacent to the electric heater 52 , so that the distance between the sub-electrical control box body 62 and the electric heater 52 can be shortened, facilitating the connection between the electric heating control component 64 in the sub-electrical control box body 62 and the electric heater 52 , making the overall structure more compact.

According to some embodiments of the present application, referring to FIG. 6 and FIG. 16 , the sub-electrical control box body 62 is connected to the upper part of the main electric control box body 61, and the sub-electrical control box body 62 is located on the side of the main electric control box body 61 adjacent to the electric heater 52. In some embodiments of the present application, the electric heater 52 is located directly above the water circuit heat exchanger 51, and the electric heating control component 64 is located in the sub-electrical control box body 62. This arrangement can make the sub-electrical control box body 62 and the electric heater 52 both located at the upper part of the water circuit heat exchange component 40. On the one hand, the distance between the sub-electrical control box body 62 and the electric heater 52 can be shortened, which facilitates the connection between the electric heating control component 64 in the sub-electrical control box body 62 and the electric heater 52, making the overall structure more compact. On the other hand, when the second electric control box component 50 is installed in the outdoor unit 100, this arrangement can make full use of the overall upper space and improve the utilization rate of the overall space.

For example, the first main control board 63163 can be partially used to control at least one of the electronic expansion valve and the four-way valve 27 of the refrigerant flow path; or the first main control board 63163 is used to control at least one of the electronic expansion valve and the four-way valve 27 of the refrigerant flow path. The second main control board 63263 is at least used to control the water pump 53. The second main control board 63263 is partially used to control the water pump 53, or the second main control board 63263 is fully used to control the water pump 53. The first main control board 63163 and the second main control board 63263 are arranged in the up and down direction, which can make the internal space layout of the main control box more reasonable and the internal structure more compact. At the same time, it can facilitate the circuit layout of the first main control board 63163 and the second main control board 63263, and facilitate the replacement and maintenance of the first main control board 631 and the second main control board 632.

According to some embodiments of the present application, referring to FIGS. 13-15 , the first water outlet 514 is connected to the second water inlet 521 through a connecting pipe 56, the first water inlet 513 is connected to the water inlet pipe 54, and the second water outlet 522 is connected to the water outlet pipe 55, the external water flow can flow into the water heat exchange assembly 40 through the water inlet pipe 54, the water flow in the water inlet pipe 54 flows into the water heat exchanger 51 through the first water inlet 513, and after heat exchange with the refrigerant flow path in the water heat exchanger 51, it can flow out of the water heat exchanger 51 from the first water outlet 514 and enter the connecting pipe 56. Then the water flow in the connecting pipe 56 can flow into the electric heater 52 through the second water inlet 521, and after the water flow is heated inside the electric heater 52, it can flow out of the electric heater 52 from the second water outlet 522, and finally flow out of the water heat exchange assembly 40 through the water outlet pipe 55 and enter the room.

At least one of the water inlet pipe 54 and the first water inlet 513, the water outlet pipe 55 and the second water outlet 522, the connecting pipe 56 and the first water outlet 514, and the connecting pipe 56 and the second water inlet 521 is connected by a quick plug-in structure. The quick plug-in structure can facilitate the installation and removal of the water inlet pipe 54, the water outlet pipe 55, and the connecting pipe 56, and facilitate the replacement and maintenance of the water inlet pipe 54, the water outlet pipe 55, and the connecting pipe 56, and at the same time can improve the overall installation efficiency of the water channel heat exchange assembly 40.

For example, one of the water outlet pipe 55 and the second water outlet 522, the water inlet pipe 54 and the first water inlet 513, the connecting pipe 56 and the first water outlet 514, and the connecting pipe 56 and the second water inlet 521 is connected by a quick plug-in structure 58, or two of the water outlet pipe 55 and the second water outlet 522, the water inlet pipe 54 and the first water inlet 513, the connecting pipe 56 and the first water outlet 514, and the connecting pipe 56 and the second water inlet 521 are connected by a quick plug-in structure. The connection is either between the water outlet pipe 55 and the second water outlet 522, between the water inlet pipe 54 and the first water inlet 513, between the connecting pipe 56 and the first water outlet 514, and between the connecting pipe 56 and the second water inlet 521, or the water outlet pipe 55 and the second water outlet 522, between the water inlet pipe 54 and the first water inlet 513, between the connecting pipe 56 and the first water outlet 514, and between the connecting pipe 56 and the second water inlet 521 are all connected by a quick plug-in structure.

According to some embodiments of the present application, referring to FIG. 2 , the outdoor unit 100 includes a second middle partition 121 disposed in the outdoor housing 10. The second middle partition 121 can separate the compressor assembly 20 from the water path heat exchange assembly 40, making the overall layout more reasonable and facilitating overall replacement and maintenance. The electric heater 52 is installed on the second middle partition 121, thereby facilitating the installation and fixation of the electric heater 52, and can also make the overall structure more compact, thereby improving the overall space utilization.

For example, the lower part and the upper part of the electric heater 52 are both provided with connection brackets, and the connection brackets are connected to the second middle partition plate 121. The connection brackets can support and fix the electric heater 52, and improve the stability and reliability of the connection of the electric heater 52.

According to some embodiments of the present application, referring to FIG. 2 and FIG. 18-FIG. 19, a vibration reduction structure 14 is provided between the bottom surface of the compressor 21 and the chassis 16 of the outdoor housing 10, and the vibration reduction structure 14 can have a vibration reduction effect on the compressor assembly 20, thereby reducing the overall noise. During the operation of the outdoor unit 100, the vibration transmitted from the compressor assembly 20 to the chassis 16 will be attenuated by the vibration reduction structure 14, thereby reducing the vibration transmitted to the chassis 16 of the outdoor housing 10, thereby reducing the noise generated when the outdoor unit 100 is in operation, and making the vibration and noise transmitted to the outside of the compressor assembly 20 smaller.

The vibration reduction structure 14 includes: a floating plate 141, a first vibration reduction member 142 and a second vibration reduction member 143. The first vibration reduction member 142 and the second vibration reduction member 143 can both reduce the vibration transmitted from the compressor 21 to the chassis 16, thereby reducing the overall noise. The floating plate 141 is located on the bottom surface of the compressor 21, the first vibration reduction member 142 is arranged between the compressor 21 and the floating plate 141, and the second vibration reduction member 143 is arranged between the floating plate 141 and the chassis 16. In this arrangement, when the compressor 21 vibrates, the vibration of the compressor 21 can be first transmitted to the floating plate 141 and then transmitted to the chassis 16. In the process of transmitting the vibration of the compressor 21 to the floating plate 141, the first vibration reduction member 142 arranged between the compressor 21 and the floating plate 141 can first reduce the vibration of the compressor 21. During the process of transmitting the reduced vibration from the floating plate 141 to the chassis 16, the second vibration damper 143 disposed between the floating plate 141 and the chassis 16 can reduce the vibration for a second time. Thus, the first vibration damper cooperates with the second vibration damper 143 to achieve secondary attenuation of the vibration of the compressor 21 during the process of transmitting the vibration to the chassis 16, thereby achieving a better overall vibration reduction and noise reduction effect.

For example, the first vibration damping member 142 and the second vibration damping member 143 may both be rubber members. Rubber members have the characteristic of high elasticity, which can make the first vibration damping member 142 and the second vibration damping member 143 have good vibration damping effect.

According to some embodiments of the present application, referring to Figures 18 to 20, the floating plate 141 is formed with an avoidance gap 1411. The avoidance gap 1411 can prevent the floating plate from interfering with other structures or components, facilitate the installation and removal of the floating plate, ensure the normal use of the vibration reduction structure, and make the overall structure more compact, which is conducive to improving the overall space utilization.

For example, the avoidance gap 1411 can be used to avoid the refrigerant pipeline between the compressor assembly 20 and other components, or the avoidance gap 1411 is used to avoid other structures on the chassis. When the avoidance gap 1411 is used to avoid the refrigerant pipeline, a certain distance can be provided between the refrigerant pipeline and the floating plate 141 to avoid contact between the refrigerant pipeline and the floating plate 141, thereby preventing the floating plate 141 from transmitting the vibration of the compressor assembly 20 to the refrigerant pipeline, affecting the overall vibration reduction and noise reduction effect. At the same time, the problem of friction between the floating plate 141 and the refrigerant pipeline caused by the vibration of the compressor assembly 20, resulting in damage to the refrigerant pipeline, can be avoided, thereby extending the service life of the refrigerant pipeline.

For example, the avoidance gap 1411 may be in the form of a groove, or a corner of the floating plate may be cut off so that the avoidance gap is formed at the position where the corner is missing.

According to some embodiments of the present application, referring to FIGS. 18 to 20 , the compressor assembly 20 further includes a liquid reservoir 22 connected to the compressor 21, and a plurality of first mounting holes 144 for mounting the compressor 21 and a plurality of second mounting holes 145 for mounting the floating plate 141 are formed on the floating plate 141. For example, the compressor 21 and the floating plate 141 can be fastened and connected by a first fastener penetrating through the first mounting hole 144, and the structure is simple, which is convenient for the installation and removal of the compressor 21. The first fastener can be sequentially penetrating through the compressor 21, the first vibration damper 142 and the floating plate 141 in the up-down direction, so that the first vibration damper 142 is fixed between the compressor 21 and the floating plate 141, thereby attenuating the vibration transmitted from the compressor 21 to the floating plate 141. The floating plate 141 and the chassis 16 can be fastened and connected by a second fastener penetrating through the second mounting hole 145, and the structure is simple, which is convenient for the installation and removal of the floating plate 141. The second fastener may be sequentially arranged through the floating plate 141, the second vibration damper 143 and the chassis 16 in the up-down direction, so that the second vibration damper 143 is fixed between the floating plate 141 and the chassis 16, thereby attenuating the vibration transmitted from the floating plate 141 to the chassis 16. Thus, the first mounting hole 144 is used for mounting the compressor 21 and the floating plate 141, and the second mounting hole 145 is used for mounting the floating plate 141 and the chassis 16.

The centers of the plurality of first mounting holes 144 are located on the first reference circle a1, so that the distances between the plurality of first mounting holes 144 and the center o1 of the first reference circle a1 are all the same. And the plurality of first mounting holes 144 can be evenly spaced along the circumference of the first reference circle a1, so that the floating plate 141 can support the compressor 21 more stably. The centers of the plurality of second mounting holes 145 are located on the second reference circle a2, so that the distances between the plurality of second mounting holes 145 and the center o2 of the second reference circle a2 are all the same. And the plurality of second mounting holes 145 can be evenly spaced along the circumference of the second reference circle a2, so that the chassis 16 of the outdoor unit 100 can support the floating plate 141 more stably.

For example, there may be three first mounting holes 144, which are evenly spaced and arranged along the circumference of the first reference circle a1, which can ensure the stability and reliability of the connection between the compressor 21 and the floating plate 141. There may be four second mounting holes 145, which are evenly spaced and arranged along the circumference of the second reference circle a2, which can improve the stability and reliability of the connection between the floating plate 141 and the chassis 16.

The center o2 of the second reference circle a2 is spaced apart from the projection of the center o1 of the first reference circle a1 on the same horizontal plane. The center o2 of the second reference circle a2 is located on the side of the center o1 of the first reference circle a1 adjacent to the liquid reservoir 22. The floating plate 141 is provided on the bottom surface of the compressor 21. Since the liquid reservoir 22 is connected to the compressor 21, the floating plate 141 supports both the compressor 21 and the liquid reservoir 22. Generally, in order to stably mount the compressor 21 on the floating plate 141, the multiple connection points between the compressor 21 and the floating plate 141 (i.e., the multiple first mounting holes 144 mentioned above) are evenly distributed and located on the same circle, and the center of the circle where the multiple connection points between the compressor 21 and the floating plate 141 are located is roughly coincident with the projection of the center of the compressor 21 on the horizontal plane, and the center of mass of the compressor assembly 20 with the liquid reservoir 22 is deviated from the center of the compressor 21 and is located on the side of the center of the compressor 21 adjacent to the liquid reservoir 22.

By locating the center o2 of the second reference circle a2 on the side of the center o1 of the first reference circle a1 adjacent to the liquid reservoir 22, that is, making the installation center of the floating plate 141 (that is, the center o2 of the second reference circle a2) deviate from the installation center of the compressor 21 (the center o1 of the first reference circle a1), and making the installation center of the floating plate 141 located on the side of the installation center of the compressor 21 adjacent to the liquid reservoir 22, the projection of the installation center of the floating plate 141 on the horizontal plane can be made closer to the projection of the center of mass of the compressor assembly 20 on the horizontal plane, so that the floating plate 141 can support the compressor assembly 20 more stably, thereby improving the vibration isolation rate of the vibration reduction structure 14.

According to some embodiments of the present application, referring to Figure 20, a plurality of second mounting holes 145 for mounting the floating plate 141 are formed on the floating plate 141, and the centers of the plurality of second mounting holes 145 are located on the second reference circle a2, so that the distances between the plurality of second mounting holes 145 and the center o2 of the second reference circle a2 are the same, and the plurality of second mounting holes 145 can be evenly spaced along the circumference of the second reference circle a2.

Among them, the projections of the centroid of the compressor assembly 20 and the center o2 of the second reference circle a2 on the same horizontal plane are the first projection point and the second projection point, respectively, and the horizontal spacing between the first projection point and the second projection point is 0 to 5 mm. The compressor assembly 20 includes a compressor 21 and a liquid reservoir 22 connected to the compressor 21, and the compressor assembly 20 as a whole can be arranged on the floating plate 141 through the compressor 21. The horizontal spacing between the first projection point and the second projection point ranges from 0 to 5 mm, which can make the distance between the centroid of the compressor assembly 20 and the installation center of the floating plate 141 (i.e., the center o2 of the second reference circle a2) in the horizontal direction shorter, so that the floating plate 141 can support the compressor assembly 20 more stably, thereby enhancing the vibration reduction effect of the vibration reduction structure 14 and improving the vibration isolation rate of the vibration reduction structure 14.

The smaller the horizontal distance between the first projection point and the second projection point, the better the overall vibration reduction effect of the vibration reduction structure 14, and the higher the vibration isolation rate of the vibration reduction structure 14. When the horizontal distance between the first projection point and the second projection point is 0 mm, that is, the first projection point coincides with the second projection point, the vibration reduction effect of the vibration reduction structure 14 can be best.

According to some embodiments of the present application, with reference to FIG. 20 , the projections of the center of mass of the floating plate 141 and the center o2 of the second reference circle a2 on the same horizontal plane are the third projection point and the second projection point, respectively, and the horizontal spacing between the third projection point and the second projection point is 0 to 5 mm. This arrangement can shorten the distance in the horizontal direction between the center of mass of the floating plate 141 and the installation center of the floating plate 141 (i.e., the center o2 of the second reference circle a2), so that the floating plate 141 can support the compressor assembly 20 more stably, thereby enhancing the vibration reduction effect of the vibration reduction structure 14 and improving the vibration isolation rate of the vibration reduction structure 14.

The smaller the horizontal distance between the second projection point and the third projection point, the better the overall vibration reduction effect of the vibration reduction structure 14, and the higher the vibration isolation rate of the vibration reduction structure 14. When the horizontal distance between the second projection point and the third projection point is 0 mm, that is, the second projection point coincides with the third projection point, the vibration reduction effect of the vibration reduction structure 14 can be best.

According to some embodiments of the present application, the projections of the centroid of the compressor assembly 20 and the centroid of the floating plate 141 on the same horizontal plane are the first projection point and the third projection point, respectively, and the horizontal spacing between the first projection point and the third projection point is 0 to 5 mm. This arrangement can shorten the distance between the centroid of the compressor assembly 20 and the centroid of the floating plate 141 in the horizontal direction, so that the floating plate 141 can support the compressor assembly 20 more stably, and can improve the stability of the compressor assembly 20 and the floating plate 141 as a whole, thereby enhancing the vibration reduction effect of the vibration reduction structure 14 and improving the vibration isolation rate of the vibration reduction structure 14.

The smaller the horizontal distance between the first projection point and the third projection point, the better the overall vibration reduction effect of the vibration reduction structure 14, and the higher the vibration isolation rate of the vibration reduction structure 14. When the horizontal distance between the first projection point and the third projection point is 0 mm, that is, the first projection point coincides with the third projection point, the vibration reduction effect of the vibration reduction structure 14 can be best.

According to some embodiments of the present application, the mass ratio of the floating plate 141 to the compressor 21 ranges from 0.1 to 0.6. The numerical unit of the mass of the floating plate 141 is consistent with the numerical unit of the mass of the compressor 21. If the mass ratio of the floating plate 141 to the mass of the compressor 21 is too small, when the compressor 21 is working, the floating plate 141 will vibrate to a large extent under the action of the compressor 21, so that the vibration reduction effect of the vibration reduction structure 14 on the compressor assembly 20 is poor. If the mass ratio of the floating plate 141 to the mass of the compressor 21 is too large, the mass of the floating plate 141 itself will be too large, thereby increasing the production cost of the floating plate 141 and making it inconvenient to install the floating plate 141 as a whole.

Therefore, when the mass ratio of the floating plate 141 to the mass of the compressor 21 is in the range of 0.1 to 0.6, the overall vibration reduction effect of the vibration reduction structure 14 can be improved, while ensuring that the mass of the floating plate 141 is appropriate and reducing the production cost of the floating plate 141. For example, the mass ratio of the floating plate 141 to the compressor 21 can be 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, etc.

Optionally, the mass ratio of the floating plate 141 to the compressor 21 is 0.1 to 0.4, which can better improve the overall vibration reduction effect of the vibration reduction structure 14, and at the same time can better ensure that the mass of the floating plate 141 is appropriate, and reduce the production cost of the floating plate 141. For example, when the mass ratio of the floating plate 141 to the compressor 21 is 0.15, the overall vibration reduction effect of the vibration reduction structure 14 can be better, and at the same time can ensure that the mass of the floating plate 141 is more appropriate.

According to some embodiments of the present application, the ratio of the static stiffness of the first vibration damper 142 to the static stiffness of the second vibration damper 143 is in the range of 0.6 to 1.5. If the ratio of the static stiffness of the first vibration damper 142 to the static stiffness of the second vibration damper 143 is too large, the vibration damping effect of the first vibration damper 142 and the second vibration damper 143 will be poor, thereby reducing the overall vibration damping effect of the vibration damping structure 14. If the stiffness ratio of the first vibration damper 142 to the second vibration damper 143 is too small, the stability of the first vibration damper 142 and the second vibration damper 143 will be poor, and they will be easily damaged, thereby reducing the service life of the vibration damping structure 14.

Therefore, the static stiffness ratio of the first vibration damper 142 and the second vibration damper 143 is 0.6 to 1.5, which can improve the overall vibration damping effect of the vibration damping structure 14, and at the same time avoid damage to the first vibration damper 142 and the second vibration damper 143, thereby ensuring the normal performance of the vibration damping structure 14. For example, the static stiffness ratio of the first vibration damper 142 to the static stiffness of the second vibration damper 143 can be 0.6, 1, 1.2, 1.5, etc.

Optionally, the static stiffness ratio of the first vibration damper 142 and the second vibration damper 143 is 0.8 to 1.2. This can better improve the overall vibration damping effect of the vibration damping structure 14, and at the same time better avoid damage to the first vibration damper 142 and the second vibration damper 143, thereby ensuring the normal use performance of the vibration damping structure 14. For example, when the static stiffness ratio of the first vibration damper 142 and the second vibration damper 143 is 1.0, the overall vibration damping effect of the vibration damping structure 14 can be better, and at the same time, the normal use of the vibration damping structure 14 can be better guaranteed.

According to some embodiments of the present application, the damping ratio of the first vibration damper 142 and the second vibration damper 143 ranges from 0.01 to 0.7. If the damping ratio of the first vibration damper 142 and the second vibration damper 143 is too large, the vibration isolation effect of the vibration damping structure 14 will be poor when the compressor 21 is working. If the damping ratio of the first vibration damper 142 and the second vibration damper 143 is too small, the vibration amplitude of the floating plate 141 will be too large, thereby causing the first vibration damper 142 and the second vibration damper 143 to fail, thereby damaging the vibration damping structure 14 and having no vibration damping effect.

Therefore, the damping ratio range of the first vibration damping member 142 and the second vibration damping member 143 is 0.01-0.7, which can improve the overall vibration damping effect of the vibration damping structure 14. When the first vibration damper 142 and the second vibration damper 143 fail, the normal performance of the vibration damping structure 14 is ensured. For example, the damping ratios of the first vibration damper 142 and the second vibration damper 143 can be 0.01, 0.2, 0.5, 0.7, etc.

Optionally, the damping ratios of the first vibration damper 142 and the second vibration damper 143 are both 0.05-0.2, which can improve the overall vibration damping effect of the vibration damping structure 14, and can better avoid the failure of the first vibration damper 142 and the second vibration damper 143, and ensure the normal use performance of the vibration damping structure 14. For example, when the damping ratios of the first vibration damper 142 and the second vibration damper 143 are both 0.05, the overall vibration damping effect of the vibration damping structure 14 can be better, and the normal use of the vibration damping structure 14 can be better guaranteed.

According to some embodiments of the present application, the static displacement of the first vibration damper 142 and the second vibration damper 143 is less than 2.5 mm, and the static displacement is the maximum deformation of the vibration damper in the vertical direction. Since the first vibration damper 142 and the second vibration damper 143 have a certain elasticity, when the compressor assembly 20 is stationary, under the action of the gravity of the compressor assembly 20, the first vibration damper 142 and the second vibration damper 143 will be deformed, and the static displacement is the maximum deformation of the first vibration damper 142 and the second vibration damper 143 in the vertical direction. If the static displacement of the first vibration damper 142 and the second vibration damper 143 is greater than 2.5 mm, the overall stability of the compressor assembly 20 will be poor, the vibration amplitude of the compressor assembly 20 will be large, and it is easy to cause the first vibration damper 142 and the second vibration damper 143 to fail. Therefore, the static displacements of the first vibration damper 142 and the second vibration damper 143 are both less than 2.5 mm, so that the first vibration damper 142 and the second vibration damper 143 can have a better vibration and noise reduction effect on the compressor assembly 20, while avoiding the failure of the first vibration damper 142 and the second vibration damper 143 and other problems, thereby ensuring the normal use of the first vibration damper 142 and the second vibration damper 143.

According to some embodiments of the present application, referring to FIG. 21 , the outdoor unit 100 further includes: an auxiliary fixing assembly 60, which is detachably connected to the outdoor housing 10 and the floating plate 141, so as to fix the floating plate 141 relative to the outdoor housing 10. Since the first vibration damper 142 and the second vibration damper 143 have certain elastic properties, the compressor 21 and the chassis 16 are elastically or flexibly connected. During the transportation of the whole machine, the compressor assembly 20 will shake, and the floating plate 141 is arranged on the bottom surface of the compressor 21, so that the floating plate 141 will also shake with the compressor 21. During the transportation, if the auxiliary fixing assembly 60 is not provided, when the vibration amplitude of the compressor assembly 20 is too large, the first vibration damper 142 and the second vibration damper 143 may fail, causing damage to the vibration damping structure 14, and affecting the overall vibration reduction and noise reduction effect.

Thus, by fixing the floating plate 141 relative to the outdoor housing 10 through the auxiliary fixing assembly 60, the failure of the first vibration damping member 142 and the second vibration damping member 143 caused by the violent shaking of the compressor assembly 20 can be prevented, thereby improving the safety and reliability of the vibration damping structure 14 and ensuring the vibration and noise reduction effect of the vibration damping structure 14 on the compressor assembly 20. For example, when the outdoor unit 100 is being transported, the auxiliary fixing assembly 60 needs to be installed to improve the safety and reliability of the vibration damping structure 14. When the outdoor unit 100 is working, the auxiliary fixing assembly 60 needs to be removed to ensure that the vibration damping structure 14 can be used normally.

According to some embodiments of the present application, referring to FIG. 21 , the auxiliary fixing member includes at least one of a bolt 7 and a fixing bracket 8, for example, the auxiliary fixing member may include a bolt 7 or a fixing bracket 8, or the auxiliary fixing member may include a bolt 7 and a fixing bracket 8. The bolt 7 is suitable for being threadedly connected to the floating plate 141 and the chassis 16 of the outdoor housing 10, and the method of relatively fixing the floating plate 141 and the chassis 16 by the bolt 7 can have the advantages of simple structure, reliable connection, and easy disassembly and installation.

The fixed bracket 8 includes a connected fixed plate 81 and a connecting plate 82. The connecting plate 82 is detachably connected to the chassis 16 of the outdoor housing 10. The fixed plate 81 is directly or indirectly pressed on the top of the floating plate 141 to press the floating plate 141 downward. Therefore, when the fixed bracket 8 is used as a whole, the fixed plate 81 can limit the floating plate 141 and the compressor 21. The connection between the connecting plate 82 and the chassis 16 can achieve the fixing effect of the fixed bracket 8 as a whole, so that the fixed bracket 8 can achieve a better fixing effect on the floating plate 141, ensuring the safety and reliability of the vibration reduction structure 14. In addition, the connecting plate 82 is detachably connected to the chassis 16, which can facilitate the installation and removal of the fixed bracket 8.

The fixing plate 81 may be provided with a limiting groove 811. When the fixing bracket 8 is used as a whole, the first fastener between the floating plate 141 and the compressor 21 and the second fastener between the floating plate 141 and the chassis 16 may be partially accommodated in the limiting groove 811, so that the movement of the floating plate 141 and the compressor 21 in the horizontal direction can be better limited, and the safety and reliability of the vibration reduction structure 14 can be ensured. For example, the fixing bracket 8 may be an integrally formed part, which can improve the structural strength and rigidity of the connection between the fixing plate 81 and the connecting plate 82, and prevent the fixing bracket 8 from breaking due to stress concentration.

According to some embodiments of the present application, the soundproof cover 25 is supported on the floating plate 141, and the soundproof cover 25 is connected to the floating plate 141. Since the second vibration damper 143 is provided between the floating plate 141 and the chassis 16, when the compressor assembly 20 is working, the compressor assembly 20 will transmit the vibration to the soundproof cover 25, and the vibration transmitted to the chassis 16 by the soundproof cover 25 can be attenuated by the second vibration damper 143, which can prevent the vibration of the compressor assembly 20 from being directly transmitted to the chassis 16 through the soundproof cover 25, thereby improving the overall vibration reduction and noise reduction effect on the compression assembly.

According to some embodiments of the present application, referring to FIG. 24 , the compressor assembly 20 further includes a liquid reservoir 22, which is fixed to the chassis 16 of the outdoor housing 10. In the related art, the liquid reservoir 22 of the compressor assembly 20 is fixed to the compressor 21 and the liquid reservoir 22 is in a suspended state. When the compressor 21 vibrates, the liquid reservoir 22 will also resonate with the compressor 21, thereby increasing the vibration of the compressor assembly 20 as a whole, thereby causing the overall noise to increase. The liquid reservoir 22 is fixed to the chassis 16, and the return air port 222 of the compressor 21 can be connected to the liquid reservoir 22 through a liquid reservoir pipe 211. The chassis 16 can stably support the liquid reservoir 22 and also prevent the liquid reservoir 22 from being in a suspended state. When the compressor 21 vibrates, the chassis 16 can ensure the stability of the liquid reservoir 22 and reduce the vibration of the liquid reservoir 22, thereby reducing the vibration of the compressor assembly 20 as a whole and reducing the overall noise.

According to some embodiments of the present application, referring to FIG. 25 , the outer cover of the compressor assembly 20 is provided with a soundproof cover 25. The compressor 21 radiates noise to the outside during operation, and the soundproof cover 25 is provided on the outside of the compressor assembly 20, which can reduce the noise radiated to the outside by the compressor assembly 20 and provide a soundproofing effect on the compressor assembly 20. The soundproof cover 25 is connected to the chassis 16, which can make the overall fixation of the soundproof cover 25 more stable, thereby improving the stability and reliability of the soundproof cover 25 when in use.

A vibration-damping pad is provided between the sound insulation cover 25 and the chassis 16, which can isolate the vibration transmitted from the sound insulation cover 25 to the chassis 16, thereby preventing the vibration of the sound insulation cover 25 from being transmitted to the chassis 16 and causing vibration and noise in the chassis 16, thereby ensuring the overall noise reduction and sound insulation effect of the compressor assembly 20.

According to some embodiments of the present application, the outer cover of the compressor assembly 20 is provided with a soundproof cover 25. The compressor 21 will radiate noise to the outside during operation. The soundproof cover 25 is arranged on the outside of the compressor assembly 20, which can reduce the noise radiated to the outside by the compressor assembly 20 and has a soundproofing effect on the compressor assembly 20. Among them, the outdoor housing 10 has a fan cavity 11 and a compressor cavity 12, and a first middle partition 113 is arranged between the fan cavity 11 and the compressor cavity 12. The outdoor heat exchanger 112 and the outdoor fan 111 are arranged in the fan cavity 11, and the compressor assembly 20 is arranged in the compressor cavity 12. The fan cavity 11 and the compressor cavity 12 can be separated by the first middle partition 113, which can make the layout of the whole machine more reasonable and facilitate the maintenance and replacement of different components.

The soundproof cover 25 is connected to the first middle partition 113. This arrangement can make the overall fixation of the soundproof cover 25 more stable, and improve the stability and reliability of the soundproof cover 25 when in use. A vibration isolation pad is provided between the soundproof cover 25 and the first middle partition 113, which can isolate the vibration transmitted from the soundproof cover 25 to the first middle partition 113, and avoid the vibration of the soundproof cover 25 being transmitted to the first middle partition 113, causing the first middle partition 113 to generate vibration and noise, thereby ensuring the overall noise reduction and sound insulation effect of the compressor assembly 20.

According to some embodiments of the present application, referring to Figures 25 to 28, the external cover of the compressor assembly 20 is provided with a sound insulation cover 25. The compressor 21 will radiate noise to the outside during operation. The sound insulation cover 25 is provided on the outside of the compressor assembly 20, which can reduce the noise radiated from the compressor assembly 20 to the outside and have a sound insulation effect on the compressor assembly 20.

The soundproof cover 25 includes a cover body 252 and a top cover 251. The top cover 251 is arranged on the top of the cover body 252. A pipeline outlet 2513 is formed on the top cover 251. The pipeline of the compressor assembly 20 is suitable for being led out from the pipeline outlet 2513. The pipeline outlet 2513 on the top cover 251 can be used to lead out the pipeline of the compressor assembly 20, which is convenient for connecting the compressor assembly 20 inside the soundproof cover 25 with external components. For example, both the cover body 252 and the top cover 251 are provided with flanges, and the flanges are provided with connection holes, so that the cover body 252 and the top cover 251 can be connected by fasteners, which has a simple structure and reliable connection, and is convenient for the installation and disassembly of the soundproof cover 25 as a whole.

According to some embodiments of the present application, referring to Figures 25-26, the top cover 251 includes a first cover body 2511 and a second cover body 2512 detachably connected in a horizontal direction, and the first cover body 2511 and the second cover body 2512 jointly define a pipeline outlet 2513, which can facilitate the pipeline of the compressor assembly 20 to be led out from the pipeline outlet 2513. When installing the top cover 251, the first cover body 2511 can be fixed on one side of the pipeline of the compressor assembly 20, and then the second cover body 2512 can be fixed on the other side of the pipeline of the compressor assembly 20, so that the pipeline of the compressor assembly 20 can be led out from the pipeline outlet 2513. The structure is simple and the operation is convenient.

According to some embodiments of the present application, referring to FIGS. 27-28 , the top cover 251 is an integrally formed part, which can increase the structural strength and rigidity of the top cover 251 and improve the overall assembly efficiency of the soundproof cover 25. For example, when the top cover 251 is an integrally formed part, the projection shape of the pipeline outlet 2513 on the top cover 251 on the horizontal plane can be U-shaped, and the pipeline outlet 2513 can pass through the side of the top cover 251.

According to some embodiments of the present application, referring to FIGS. 25-27 , a second sealing structure 2514 is provided on the top cover 251, and the second sealing structure 2514 is used to seal the gap between the pipeline of the compressor assembly 20 and the inner wall of the pipeline outlet 2513. With this arrangement, on the one hand, the first sealing structure 3152 can prevent noise from leaking from the pipeline outlet 2513, thereby better ensuring the noise reduction and sound insulation effect of the soundproof cover 25 on the internal compressor assembly 20. On the other hand, the second sealing structure 2514 can prevent external liquid from entering the soundproof cover 25, ensuring the normal use of the compressor assembly 20. For example, the second sealing structure 2514 can be a porous material or an elastic rubber material, etc., which can ensure the noise reduction and sound insulation effect of the two sealing structures.

According to some embodiments of the present application, referring to FIGS. 25-27 , the cover 252 and the top cover 251 are formed independently, which can facilitate the assembly and disassembly between the soundproof cover 25 and the compressor assembly 20. The cover 252 includes a first sub-cover 2521 and a second sub-cover 2522 that are detachably connected in the horizontal direction, which can facilitate the installation and disassembly of the cover 252 as a whole, and facilitate the replacement and maintenance of the cover 252 as a whole. For example, the left and right sides of the first sub-cover 2521 and the second sub-cover 2522 can be provided with flanges, and the flanges can be provided with screw holes or snap-on structures, so that the first sub-cover 2521 and the second sub-cover 2522 can be connected by fasteners or snap-on structures, with a simple structure and reliable connection, which facilitates the installation and disassembly of the cover 252 as a whole. The projection shapes of the first sub-cover 2521 and the second sub-cover 2522 on the horizontal plane can both be U-shaped. Alternatively, one of the first sub-cover body 2521 and the second sub-cover body 2522 is a flat plate, and the projection shape of the other on the horizontal plane is U-shaped.

According to some embodiments of the present application, the cover body 252 is an integrally formed part, which can increase the structural strength and rigidity of the cover body 252, ensure the overall stability and reliability of the cover body 252, and at the same time reduce the number of overall parts and improve the overall assembly efficiency of the sound insulation cover 25.

According to some embodiments of the present application, referring to FIG. 3 and FIG. 28 , a first intermediate partition 113 is provided between the fan chamber 11 and the compressor chamber 12, and the fan chamber 11 and the compressor chamber 12 in the outdoor housing 10 can be separated by the first intermediate partition 113, so that the layout of the whole machine can be more reasonable, and it is convenient to repair and replace different components. A second intermediate partition 121 is provided between the waterway chamber 13 and the compressor chamber 12, and part of the space in the outdoor housing 10 is divided into the waterway chamber 13 and the compressor chamber 12 by the second intermediate partition 121, so that the layout of the whole machine can be more reasonable, and it is convenient to repair and replace different components.

At least part of the first middle partition 113 constitutes part of the cover 252, for example, part of the first middle partition 113 constitutes part of the cover 252 or the first middle partition 113 completely constitutes part of the cover 252. This arrangement can reduce the overall space occupied by the sound insulation cover 25, make the structure in the compressor chamber 12 more compact, and also save the overall cost of the sound insulation cover 25.

According to some embodiments of the present application, referring to Fig. 3 and Fig. 28, at least part of the second middle partition 121 constitutes part of the cover 252, for example, part of the second middle partition 121 constitutes part of the cover 252 or the entire second middle partition 121 constitutes part of the cover 252. This arrangement can reduce the overall space occupied by the cover 252, making the structure in the compressor chamber 12 more compact, and can also save the overall cost of the soundproof cover 25.

According to some embodiments of the present application, referring to Fig. 3-Fig. 4 and Fig. 28, the first middle partition plate 113 and the second middle partition plate 121 are opposite to each other in the left-right direction, and the first middle partition plate 113 and the second middle partition plate 121 are arranged at intervals. The first middle partition plate 113 and the second middle partition plate 121 can sequentially separate the outdoor housing 10 into the fan chamber 11, the compressor chamber 12 and the water channel chamber 13 in the left-right direction, making the layout of the whole machine more reasonable and facilitating the maintenance and replacement of different components.

The first middle partition 113 is located on the left side of the compressor chamber 12, and the second middle partition 121 is located on the right side of the compressor chamber 12. The first middle partition 113 and the second middle partition 121 can respectively constitute the sound insulation cover 25 located on the left part and the right part of the compressor, making the overall structure more compact and improving the space utilization of the whole machine.

The soundproof cover 25 includes a first cover plate 2523, a second cover plate 2524 and a top cover 251. The first cover plate 2523 and the second cover plate 2524 are arranged opposite to each other in the front-to-back direction and are spaced apart. The left and right ends of the first cover plate 2523 and the left and right ends of the second cover plate 2524 are respectively connected to the first middle partition plate 113 and the second middle partition plate 121. The top cover 251 is arranged on the top of the first cover plate 2523 and the second cover plate 2524. This arrangement allows the first cover plate 2523, the second cover plate 2524, the top cover 251, a part of the first middle partition plate 113 and a part of the second middle partition plate 121 to jointly constitute the entire soundproof cover. Compared with the soundproof cover being independently manufactured as a whole, the soundproof cover 25 can occupy less installation space, make the structure of the whole machine more compact, and better improve the space utilization rate of the whole machine. At the same time, the overall cost of the soundproof cover 25 can be better saved.

For example, the first cover plate 2523 can be located in front of the second cover plate 2524, and the first cover plate 2523 and the second cover plate 2524 are both flat. The first cover plate 2523 and the second cover plate 2524 can be connected to the first middle partition plate 113, the second middle partition plate 121 and the top cover 251 by fasteners, which has a simple structure and reliable connection, and is convenient for the installation and disassembly of the soundproof cover as a whole, so as to facilitate the assembly of the whole machine. The top cover 251 can be provided with flanges on all sides, and fasteners can be inserted into the flanges, so as to facilitate the fixation between the top cover 251 and the first cover plate 2523, the second cover plate 2524, the first middle partition plate 113 and the second middle partition plate 121.

According to some embodiments of the present application, referring to FIG. 3-FIG. 4 and FIG. 28, the first cover plate 2523, the second cover plate 2524 and the top cover 251 are formed independently, which can facilitate the overall assembly and transportation of the soundproof cover 25, and at the same time improve the overall strength and rigidity of the soundproof cover 25. It can also simplify the processing technology of the entire soundproof cover 25 and reduce the processing difficulty of the entire soundproof cover 25.

According to some embodiments of the present application, referring to Fig. 3-Fig. 4 and Fig. 28, at least two of the first cover plate 2523, the second cover plate 2524 and the top cover 251 are integrally formed. For example, the first cover plate 2523 and the second cover plate 2524 are integrally formed, or the first cover plate 2523 and the top cover 251 are integrally formed, or the second cover plate 2524 and the top cover 251 are integrally formed, or the first cover plate 2523, the second cover plate 2524 and the top cover 251 are integrally formed.

This arrangement can increase the connection strength of the various parts of the soundproof cover 25, and improve the stability and reliability of the connection between the first cover plate 2523, the second cover plate 2524 and the top cover 251. At the same time, it can facilitate the installation and disassembly of the entire soundproof cover 25, and improve the overall assembly efficiency.

According to some embodiments of the present application, referring to Figures 3-4 and 28, the portion of the first middle partition 113 that constitutes the sound insulation cover 25 is the sound insulation portion 1137c. The sound insulation portion 1137c of the first middle partition 113 has the effect of sound insulation and noise reduction, and can effectively prevent the noise generated by the compressor assembly 20 from being transmitted to the fan cavity 11 through the first middle partition 113, thereby ensuring the overall noise reduction and sound insulation effect of the sound insulation cover 25 on the compressor assembly 20.

The soundproof cover 25 includes a third cover plate 2525 and a top cover 251. The lower end of the third cover plate 2525 is connected to the upper end of the soundproof portion 1137c, and the upper end of the third cover plate 2525 is connected to the top cover 251. A clearance space 2526 for avoiding the first electric control box component 30 is defined between the third cover plate 2525 and the first middle partition plate 113, which can avoid interference between the first electric control box component 30 and the soundproof cover 25, and ensure the normal installation of the first electric control component 30 and the soundproof cover 25. In addition, the clearance space 2526 defined between the third cover plate 2525 and the first middle partition plate 113 can make the whole machine structure more compact and improve the overall space utilization.

For example, in some specific embodiments of the present application, the soundproof cover 25 includes a first cover plate 2523, a second cover plate 2524, a third cover plate 2525 and a top cover 251, and the first cover plate 2523, the second cover plate 2524, the third cover plate 2525 and the top cover 251 are independently formed. The first cover plate 2523 and the second cover plate 2524 are opposite and spaced in the front-to-back direction, and the left and right ends of the first cover plate 2523 and the left and right ends of the second cover plate 2524 are respectively connected to the first middle partition plate 113 and the second middle partition plate 121. The front and rear ends of the third cover plate 2525 are respectively connected to the first cover plate 2523 and the second cover plate 2524 by fasteners. The front and rear ends of the third cover plate 2525 can be provided with flanges, and the fasteners can be inserted into the flanges, so that the third cover plate 2525 can be easily fixed to the first cover plate 2523 and the second cover plate 2524.

The top cover 251 is covered on the top of the first cover plate 2523, the second cover plate 2524 and the third cover plate 2525. The top cover 251 is connected to the first cover plate 2523, the second cover plate 2524, the third cover plate 2525 and the second middle partition plate 121 by fasteners, and the structure is simple, which is convenient for the installation and removal of the whole sound insulation cover 25. The four sides of the top cover 251 can be provided with flanges, and the fasteners can be inserted into the flanges, so that the top cover 251 can be easily fixed to the first cover plate 2523, the second cover plate 2524, the third cover plate 2525 and the second middle partition plate 121.

According to some embodiments of the present application, referring to FIGS. 3-4 and 28, the third cover plate 2525 includes a relief portion and an extension portion arranged at an angle, one end of the relief portion is connected to the upper end of the sound insulation portion 1137c, the other end of the relief portion extends toward the compressor chamber 12, the lower end of the extension portion is connected to the other end of the relief portion, the upper end of the extension portion extends upward and the upper end of the extension portion is connected to the top cover. In this way, the relief portion, the extension portion and the first middle partition plate 113 define a space for relief of the third cover plate 2525. The avoidance space 2526 of the first electric control box component 30 can better avoid interference between the first electric control box component 30 and the sound insulation cover 25, ensuring the normal installation of the first electric control component 30 and the sound insulation cover 25. It can also make the whole machine structure more compact and improve the overall space utilization.

According to some optional embodiments of the present application, referring to FIG29 , the outer cover of the compressor assembly 20 is provided with a soundproof cover 25, and damping particles 253 are filled between the soundproof cover 25 and the compressor assembly 20. The damping particles 253 can reduce vibration and noise of the compressor assembly 20, and the damping particles 253 are filled between the soundproof cover 25 and the compressor assembly 20, which can improve the overall vibration and noise reduction effect of the compressor assembly 20.

When the compressor assembly 20 is working, the vibration generated by the compressor assembly 20 can be transmitted to the damping particles 253, and the damping particles 253 between the soundproof cover 25 and the compressor assembly 20 can collide and rub against each other, thereby converting the vibration mechanical energy of the compressor assembly 20 into heat energy and discharging it through the soundproof cover 25, thereby slowing down the vibration of the compressor assembly 20 and reducing the working noise of the compressor assembly 20. In addition, since the damping particles 253 surround the vibration source, the sound waves of the vibration noise pass through the damping particles 253 during the transmission process and then propagate to the external environment. The damping particles 253 weaken the sound waves, thereby reducing the energy of the sound waves and further reducing the working noise of the compressor assembly 20.

According to some optional embodiments of the present application, referring to FIG. 29 , the equivalent diameter of the damping particles 253 is less than 3 mm. The mutual friction between the multiple damping particles 253 can be well achieved, thereby converting the vibration kinetic energy of the compressor assembly 20 into frictional heat energy and discharging it through the soundproof cover 25, thereby slowing down the vibration of the compressor assembly 20 and reducing the working noise of the compressor assembly 20. At the same time, the air gap between the multiple damping particles 253 can be made smaller, so that the multiple damping particles 253 can better weaken the sound waves, thereby improving the overall noise reduction effect.

According to some optional embodiments of the present application, referring to Fig. 29, the soundproof cover 25 is supported on and connected to the floating plate 141, and the damping particles 253 are filled in the space defined by the soundproof cover 25 and the floating plate 141. Thus, when the compressor assembly 20 is working, the damping particles 253 can attenuate the vibration transmitted from the compressor assembly 20 to the soundproof cover 25, and the vibration transmitted from the soundproof cover 25 to the chassis 16 can be attenuated by the second vibration damping member 143, thereby improving the vibration reduction and noise reduction effect of the compression assembly.

According to some embodiments of the present application, a second sealing structure 2514 is provided between the soundproof cover 25 and the floating plate 141 to seal the assembly gap between the soundproof cover 25 and the floating plate 141, which can prevent the damping particles 253 in the soundproof cover 25 from leaking, thereby better ensuring the vibration reduction and noise reduction effect of the damping particles 253 on the compressor assembly 20. At the same time, it can prevent the vibration and noise in the soundproof cover 25 from leaking from the assembly gap, affecting the overall vibration reduction and noise reduction effect.

According to some optional embodiments of the present application, referring to Figures 30-31, the return air pipe 221 connected to the compressor assembly 20 includes a plurality of U-shaped segments connected in sequence, and the number of the U-shaped segments is an even number. When the compressor assembly 20 is working, the vibration of the liquid reservoir 22 will be transmitted to the return air pipe 221, and the vibration of the return air pipe 221 will be transmitted to other components, thereby causing the whole machine to generate a large low-frequency noise. Providing the return air pipe 221 with a plurality of connected U-shaped pipes can increase the flexibility and structural damping of the return air pipe 221, effectively reduce the natural frequency of the return air pipe 221, and attenuate the vibration rate of the compressor 21 reservoir 22 transmitted to other components through the return air pipe 221, thereby achieving a vibration reduction and noise reduction effect.

For example, one end of the return air pipe 221 of the compressor assembly 20 is connected to the return air port 222 of the liquid reservoir 22, and the other end is connected to the four-way valve 27, and the four-way valve 27 is located above the return air pipe 221. The number of U-shaped segments is an even number, which can ensure the normal connection between the return air pipe 221 and the liquid reservoir 22 and the four-way valve 27. At the same time, it can effectively attenuate the vibration transmitted to other components by the return air pipe 221, and achieve the overall vibration reduction and noise reduction effect. For example, the number of U-shaped segments can be 2, 4, 6, etc.

According to some optional embodiments of the present application, referring to FIG. 30 , the number of U-shaped segments is 4, which can more effectively attenuate the vibration transmitted to other components by the return air duct 221, and achieve a better overall vibration reduction and noise reduction effect. At the same time, the overall size can be guaranteed, and the return air duct 221 can be prevented from occupying more space, thus saving costs.

According to some embodiments of the present application, referring to FIG. 30 , the return air pipe 221 connected to the compressor assembly 20 includes a plurality of U-shaped sections connected in sequence. When the compressor assembly 20 is working, the vibration of the liquid reservoir 22 will be transmitted to the return air pipe 221, and the vibration of the return air pipe 221 will be transmitted to other components, thereby causing the whole machine to generate a large low-frequency noise. Providing the return air pipe 221 with a plurality of connected U-shaped pipes can increase the flexibility and structural damping of the return air pipe 221, effectively reduce the natural frequency of the return air pipe 221, and attenuate the vibration rate of the compressor 21 liquid reservoir 22 transmitted to other components through the return air pipe 221, thereby achieving the effect of reducing vibration and noise.

The compressor assembly 20 includes a compressor 21 and a liquid reservoir 22. The circle obtained by taking the center of the exhaust port 212 of the compressor 21 as the center and R1 as the radius is the third reference circle, R1 is larger than the radius of the compressor 21 and the difference range is 20 to 225 mm. The circle obtained by taking the center of the return air port 222 of the liquid reservoir 22 as the center and R2 as the radius is the fourth reference circle, R2 is larger than the radius of the liquid reservoir 22 and the difference range is 20 to 200 mm. At least part of the projection of the multiple U-shaped sections of the return air pipe 221 on the horizontal plane is located in the intersection area of the third reference circle and the fourth reference circle. In this way, the distance between the multiple U-shaped sections of the return air pipe 221 and the compressor 21 and the liquid reservoir 22 is relatively close, and at the same time, the return air pipe 221 can be prevented from interfering with the compressor 21 and the liquid reservoir 22, which affects the normal use of the return air pipe 221. When the compressor 21 and the liquid reservoir 22 vibrate, the U-shaped section of the return air pipe 221 can be made more stable and the vibration amplitude can be smaller, thereby ensuring the overall vibration reduction and noise reduction effect on the compressor assembly 20. In addition, the overall structure of the compressor assembly 20 can be made more compact and the overall space utilization rate can be improved. It can also avoid the return air pipe 221 from interfering with the compressor 21 or the liquid reservoir 22, which affects the use of the compressor assembly 20.

According to some embodiments of the present application, referring to FIG. 31-FIG. 32, the return air pipe 221 connected to the compressor assembly 20 includes a plurality of U-shaped sections and vertical sections connected in sequence, the vertical section is connected between two adjacent U-shaped sections, at least part of the vertical sections are bellows or rubber hoses 2211, for example, part of the vertical sections are bellows or rubber hoses 2211 or all the vertical sections are bellows or rubber hoses 2211. When the compressor assembly 20 is working, the vibration of the reservoir 22 will be transmitted to the return air pipe 221, and the vibration of the return air pipe 221 will be transmitted to other components, so that the whole machine generates a large low-frequency noise. The return air pipe 221 is provided with a plurality of connected U-shaped pipes, which can increase the flexibility and structural damping of the return air pipe 221, can effectively reduce the natural frequency of the return air pipe 221, and attenuate the vibration rate of the compressor 21 reservoir 22 transmitted to other components through the return air pipe 221, so as to achieve the effect of vibration reduction and noise reduction.

The bellows or rubber hose 2211 has a certain elasticity. When the vibration is transmitted to the vertical section, the bellows or rubber hose 2211 can attenuate the vibration of the vertical section, thereby reducing the overall vibration of the return air pipe 221 and achieving an overall vibration reduction and noise reduction effect.

According to some embodiments of the present application, referring to FIGS. 31-32 , the length of the bellows ranges from 150 to 450 mm; or, the length of the rubber hose 2211 ranges from 150 to 450 mm. If the length of the bellows or the rubber hose 2211 is too long, the overall structural strength and rigidity of the return air pipe 221 will be poor, and it will be easily damaged during use. If the length of the bellows or the rubber hose 2211 is too short, the vibration reduction and noise reduction effect of the bellows or the rubber hose 2211 on the vertical section of the return air pipe 221 will be reduced. Therefore, when the length of the bellows ranges from 150 to 450 mm, or when the length of the rubber hose 2211 ranges from 150 to 450 mm, the vibration reduction and noise reduction effect of the bellows or the rubber hose 2211 on the vertical section of the return air pipe 221 can be better guaranteed, and the overall structural strength and rigidity of the return air pipe 221 can be guaranteed.

According to some embodiments of the present application, at least a portion of the return air pipe 221 connected to the compressor assembly 20 is a metal pipe, for example, a portion of the return air pipe 221 is a metal pipe or the entire return air pipe 221 is a metal pipe. At least a portion of the metal pipe is provided with a vibration-damping rubber sleeve or a counterweight block, for example, a portion of the metal pipe may be provided with a vibration-damping rubber sleeve or a counterweight block. When the compressor assembly 20 is working, the vibration of the liquid reservoir 22 will be transmitted to the return air pipe 221, and the vibration of the return air pipe 221 will be transmitted to other components, thereby causing the entire machine to generate a large low-frequency noise. The return air pipe 221 is provided with a vibration-damping rubber sleeve or a counterweight block, which can attenuate the vibration of the return air pipe 221, thereby achieving an overall vibration reduction and noise reduction effect on the return air pipe 221.
