Technical Field

The present application relates to the field of heat exchange systems, and in particular, to a heat exchange system capable of stably implementing a heat dissipation function.

Background

In order to provide a more convenient service for users, the number of central processing units (Central Processing Unit, CPU) provided in the server is increasing, or at least the computing power is becoming more excellent. In addition, the number of components and/or their performance of image processors (Graphics Processing Unit, GPUs), hard disks, power supplies, memories, etc. in servers are increasing day by day. However, the increase in the number of components and/or the increase in performance may also result in a significant amount of waste heat.

In order to enable the servers disposed in the cabinet to be in a normal working environment, water cooling systems are generally used nowadays to quickly remove heat generated during operation of the servers. However, not all rooms can be connected to ice water machines of a building. Or even if the water chiller of the building can be connected, the pipeline of the water chiller may be left out of management and the cooling water is excessively deteriorated, and even the water chiller is connected with other equipment to cause pollution of the cooling water. Therefore, how to provide a heat exchange system that can effectively help the heat dissipation of the servers in the cabinet and can stably operate is an urgent problem in the art.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1, a block diagram of a heat exchange system according to an embodiment of the application is shown. As shown, the heat exchange system comprises a cabinet 2 and heat exchange equipment 1. In the present application, the term "cabinet" refers to a carrier in which servers are disposed. For example, the cabinet 2 may be a server carrier located in a machine room, and the server may include, but is not limited to, a central processing unit, an image processor, a hard disk, a power supply, a memory, and the like. It should be noted that the present application is not limited to the location of the cabinet 2, and the cabinet 2 may be disposed at a location other than the machine room.

As mentioned above, the heat exchange device 1 is configured to carry away heat from the cabinet 2. More specifically, the cabinet 2 includes a heat radiation door plate 2A and a cabinet main body 2B, and the heat radiation door plate 2A is disposed on the cabinet main body 2B. The heat exchange device 1 is connected to the heat radiation door plate 2A in the cabinet 2, and takes heat away from the heat radiation door plate 2A and the cabinet main body 2B by fluid.

In the present application, the heat exchange apparatus 1 may include a miniaturized control module (e.g., a control module 13 mentioned later) and other operation components, so that the operation components including the modules are disposed in the cabinet 2. Therefore, the heat exchange device 1 of the present application does not occupy a large volume and is capable of optimizing heat dissipation for the cabinet 2. Further, since each operation module controls only the heat dissipation process of one cabinet 2, the burden of the operation module can be greatly reduced.

Based on the above explanation, it can be understood that the heat exchange system of the present application is composed of the cabinet 2 carrying the servers and the heat exchange apparatus 1 for heat dissipation. Further, for the purpose of promoting an understanding of the present application, the specific configuration and operation of the heat exchange apparatus 1 and the cabinet 2 will be described below.

Please refer to fig. 2 and fig. 3, which are a schematic diagram of a pipeline configuration and a schematic diagram of a heat exchange system according to an embodiment of the application. As shown, the heat exchange apparatus 1 includes a heat exchange module 10, a driving module 11, a buffering module 12, and a control module 13. The control module 13 is disposed in the cabinet body 2B, and the driving module 11 and the buffer module 12 may be disposed in the cabinet body 2B or outside the cabinet body 2B according to the requirement.

As shown in fig. 1, the heat exchange module 10 includes a first circulation pipe 100. The first circulation tube 100 is in fluid communication with the heat dissipating coil assembly 20 in the heat dissipating door panel 2A. Wherein the first circulation pipe 100 stores therein a first fluid L1. By placing the first circulation tube 100 in fluid communication with the heat dissipating coil assembly 20 in the heat dissipating door 2A, the first fluid L1 flowing along the first circulation tube 100 can effectively carry away heat in the cabinet 2 to maintain a stable operating temperature of the cabinet 2.

In some embodiments, the first fluid L1 may be water, an aqueous glycol solution, or a compatible cooling fluid. Preferably, the first fluid L1 may be deionized water. More preferably, the first fluid L1 is deionized water with added corrosion inhibitor and bactericide to reduce corrosion, scaling and microbial growth of the pipeline, thereby reducing heat dissipation capability and reliability. Still more preferably, the first fluid L1 is deionized water that can satisfy the following conditions:

in some embodiments, the first fluid L1 may also be a dielectric liquid that satisfies the following conditions:

in some embodiments, the first fluid L1 may also be mineral oil that satisfies the following conditions:

in some embodiments, the first fluid L1 may also be a cooling liquid that satisfies the following conditions:

in some embodiments, the temperature of the first fluid L1 ranges from 10 ℃ to 45 ℃, which needs to be above the ambient dew point. For example, the temperature of the first fluid L1 may be 10 ℃, 15 ℃, 20 ℃, 25 ℃, 30 ℃, 35 ℃, 40 ℃, 45 ℃, or any range of the above values. In practical applications, the temperature of the first fluid L1 may be adjusted according to the ambient temperature, the Central Processing Unit (CPU) condition, and/or the characteristics of the first fluid L1.

As shown in fig. 1, the heat exchange module 10 further includes a cooling device 101, and the cooling device 101 exchanges heat with the first circulation pipe 100. More specifically, the cooling apparatus 101 includes a second circulation pipe 1010 and an ice water machine 1011, a portion of the second circulation pipe 1010 penetrating into the ice water machine 1011 to transfer heat into the ice water machine 1011, the first circulation pipe 100 being in heat exchange but not fluid communication with the second circulation pipe 1010. Wherein the second circulation tube 1010 stores a second fluid L2 therein.

In some embodiments, the chiller 1011 may be a commercial or industrial large chiller that is located outside the building and exchanges heat through a cooling tower. However, the present application is not limited thereto, and the ice water machine 1011 may be a dedicated cooler or a dedicated cooling tower, which may be installed in a building.

In some embodiments, the second fluid L2 may include water, an aqueous glycol solution, but is not limited thereto. Preferably, the second fluid L2 may also comprise deionized water. More preferably, the second fluid L2 is deionized water to which a corrosion inhibitor and a bactericide are added. Still more preferably, the second fluid L2 may be identical to the first fluid L1 satisfying the conditions in the tables.

By allowing the first fluid L1 and the second fluid L2 to flow through the first circulation pipe 100 and the second circulation pipe 1010, respectively, and allowing the first fluid L1 and the second fluid L2 to approach each other (as the region a in fig. 2) for heat exchange, the present embodiment effectively conducts the heat in the cabinet 2 from the first fluid L1 and the second fluid L2 to the outside (e.g. outside the building) in sequence. It should be noted that the first fluid L1 and the second fluid L2 in the present application exchange heat only by heat conduction and heat radiation, and at most exchange heat by indirect heat convection (e.g., air possibly flowing in the area a) without actually being in fluid communication, so as to effectively avoid impurities and dirt from contaminating the first circulation pipe 100.

In this way, the application realizes a heat dissipating device with two independent loops. With the above configuration, the two independent circuits can not only effectively perform heat exchange, but also prevent impurities in one circuit from flowing into the other circuit.

As shown in fig. 3, in some embodiments, the heat exchange system of the present application may be divided into a primary side and a secondary side by using the area a where the first circulation pipe 100 exchanges heat with the second circulation pipe 1010 as a boundary. Taking the right half of fig. 3 as an example, components such as the second circulation pipe 1010 and the ice water machine 1011 are defined as a primary side fluid circuit. Taking the left half of fig. 3 as an example, components such as the first circulation pipe 100 and the cabinet 2 are defined as a secondary side fluid circuit. That is, the present application can be actually considered to be composed of fluid circuits on both the left and right sides. Accordingly, the term "second" in connection with the first set of fluid circuits of the present application may also be referred to as "primary side". For example, the elements of the "second circulation pipe", "second fluid", and "second filter" (some of which will be mentioned below) may be referred to as "primary side circulation pipe", "primary side fluid", and "primary side filter".

Similarly, the term "first" in connection with the second set of fluid circuits of the present application may also be referred to as "secondary side". For example, elements such as "first" circulation pipe, "first fluid", "control valve", "storage space", and "first filter" (some of which will be referred to hereinafter) may be referred to as "secondary side circulation pipe", "secondary side fluid", "secondary side control valve", "secondary side storage space", and "secondary side filter".

It should be appreciated that the terms "first," "second," "primary" and "secondary" are used herein merely to distinguish between different elements or components, and are not to be construed as indicating or implying relative importance or a sequential relationship thereof.

As shown in fig. 1, the driving module 11 is connected to the heat exchange module 10 and configured to drive the first fluid L1 in the first circulation pipe 100 to flow along the first circulation pipe 100. In some embodiments, the driving module 11 includes a driving pump 110, the driving pump 110 being disposed in the first circulation pipe 100 and driving the first fluid L1 in the first circulation pipe 100. For example, the actuation pump 110 may be a plunger pump in a test pump that uses a relief valve to control pressure and a throttle valve to control flow. However, the present application is not limited thereto, and pumps known to those skilled in the art may be applied to the present application. For example, the drive pump 110 may also be a metering pump, or other suitable pump.

In some embodiments, the plurality of drive pumps 110, at least one of the plurality of drive pumps 110 is in an operational state, and at least one of the plurality of drive pumps 110 is in a closed state. Taking fig. 2 as an example, the right half of fig. 2 is a partial schematic view of the first circulation pipe 100. In fig. 3, the driving pumps 110 may be two, and the two driving pumps 110 (i.e., the first driving pump 110a and the second driving pump 110 b) are respectively connected in series in the first circulation pipe 100. When one of the two drive pumps 110 is in an operating state, the other of the two drive pumps 110 is in a closed state. In this way, the whole driving module 11 drives the delivery of the first fluid L1 by only one driving pump 110, while the other driving pump 110 is used for standby. In this case, the two driving pumps 110 may be alternately turned off at a fixed period to increase the lifetime of the apparatus. In addition, by means of the alternate activation design, the drive module 11 can be made such that it does not affect the operation of the heat exchange system during repair/maintenance. It should be noted that the above number is only an example, and the driving pumps 110 in other embodiments may be three, four, or more than four, and it is consistent that at least one of the driving pumps 110 is in the off state.

As shown in fig. 1, the buffer module 12 is in fluid communication with the first circulation pipe 100, and the buffer module 12 includes a control valve 120 and a storage space 121, the control valve 120 being located between the first circulation pipe 100 and the storage space 121. In the present application, the storage space 121 may be formed by a hollow storage device such as a liquid tank, or the like, for storing or replenishing the first fluid L1.

For example, when the volume of the first fluid L1 increases due to an increase in the ambient temperature, the control valve 120 may be set to be opened to allow the first fluid L1 to flow from the first circulation pipe 100 into the storage space 121. In this way, the flow rate, pressure, etc. of the first fluid L1 in the first circulation pipe 100 can be adjusted according to the preset or real-time setting. Conversely, when the volume of the first fluid L1 decreases due to the sudden decrease of the ambient temperature, or the flow rate and pressure of the first fluid L1 need to be increased to improve the heat dissipation performance, the control valve 120 may be set to be opened to allow a portion of the first fluid L1 to flow into the first circulation pipe 100 from the storage space 121.

As shown in fig. 1, the control module 13 is disposed in the cabinet main body 2B in the cabinet 2. The control module 13 is electrically connected to the driving module 11 and the buffer module 12, and the control module 13 includes a sensing device 130. The control module 13 controls the control valve 120 to open or close according to the sensing signal S sent by the sensing device 130, and controls the driving module 11 to operate according to the sensing signal S sent by the sensing device 130. In some embodiments, sensing device 130 may include one or more of a voltage sensor, a current sensor, a fluid temperature sensor, a fluid pressure sensor, a fluid flow meter, and/or various types of sensors known to those skilled in the art to effectively monitor the status of heat exchange module 10. Specifically, the fluid temperature sensor, the fluid pressure sensor, the fluid flowmeter, and other suitable sensors generate a sensing signal S according to the measured state of the first fluid L1, and the sensing signal S may include, but is not limited to, voltage information, current information, fluid pressure information, fluid temperature information, and fluid flow information.

As shown in fig. 2, the first circulation pipe 100 in the right half may be provided with/connected with sensing means 130 such as a fluid pressure sensor 130a, a fluid pressure sensor 130b, a fluid temperature sensor 130c, a fluid temperature sensor 130d and a fluid flow meter 130e, and driving pumps 110 such as a first driving pump 110a and a second driving pump 110 b.

Wherein the fluid pressure sensor 130a is used for sensing the pressure of the first fluid L1 before being pressurized by the first driving pump 110a and/or the second driving pump 110b, the fluid pressure sensor 130b is used for sensing the pressure of the first fluid L1 after being pressurized by the first driving pump 110a and/or the second driving pump 110b, the fluid temperature sensor 130c is used for sensing the temperature (i.e. backwater state) of the first fluid L1 after absorbing heat in the cabinet 2, the fluid temperature sensor 130d is used for sensing the temperature (i.e. water outlet state) of the first fluid L1 before absorbing heat in the cabinet 2, and the fluid flow meter 130e is used for sensing the flow rate of the first fluid L1 in the first circulation pipe 100.

With the above arrangement, the control module 13 can precisely confirm the state of the first fluid L1 in the first circulation pipe 100 to instantly control the operation of the driving module 11 and/or the buffer module 12. When one or more of the temperature, pressure and flow rate of the first fluid L1 is abnormal, the control module 13 sends a control signal C according to the sensing signals S sent by the sensing devices 130 to control the driving module 11 to stop operating or control the control valve 120 to open/close so as to adjust the total amount of the first fluid L1 in the first circulation pipe 100.

It should be noted that the above configuration is only one embodiment of the present application, and the present application is not limited thereto. In other embodiments, other different types and numbers of sensors may be provided/connected to the first circulation pipe 100 to more effectively monitor the state of the heat exchange module 10.

As shown in fig. 2, a sensing device 130 such as a fluid pressure sensor 130g, a fluid pressure sensor 130h, a fluid temperature sensor 130f, and a fluid flow meter 130i may also be provided/connected to the second circulation pipe 1010 in the left half. Wherein the fluid pressure sensor 130g is used to sense the pressure of the second fluid L2, the fluid pressure sensor 130h is used to sense the pressure of the second fluid L2, the fluid temperature sensor 130f is used to sense the temperature (i.e., the backwater state) of the second fluid L2 after the heat of the first fluid L1 is extracted, and the fluid flow meter 130i is used to sense the flow rate of the second fluid L2 in the second circulation pipe 1010.

As shown in FIG. 1, in some embodiments, the control module 13 includes an operator sub-module 131 and a record sub-module 132. The operation sub-module 131 receives the sensing signal S from the sensing device 130, generates the control signal C according to the sensing signal S, and sends the control signal C to the buffer module 12 and/or the driving module 11. For example, the operation sub-module 131 may include a central processor, a micro processor, or other suitable processor, which determines according to the voltage information, the current information, the fluid pressure information, the fluid temperature information, the fluid flow information, and the like in the sensing signal S, and generates the control signal C corresponding to the sensing signal S to adjust the state of the first fluid L1 in the first circulation pipe 100 through the driving module 11 and/or the buffer module 12.

The recording sub-module 132 receives the sensing signal S from the sensing device 130 and stores the voltage information, the current information, the fluid pressure information, the fluid temperature information, and the fluid flow information in the sensing signal S. In the present application, the recording sub-module 132 may include a conventional hard disk (HDD), a solid state disk (SDD), a Random Access Memory (RAM), an optical storage device (CD, DVD), or other suitable storage device to record the above information in the sensing signal S.

In some embodiments, the recording sub-module 132 may further store predetermined voltage information, predetermined current information, predetermined fluid pressure information, predetermined fluid temperature information, and predetermined fluid flow information, and when the operator module 131 determines that the detected voltage information, current information, fluid pressure information, fluid temperature information, and fluid flow information are different from the above parameters, the operator module 131 may adjust the operation of the driving module 11 and/or the buffer module 12 according to the status, and/or send an alarm to the maintenance personnel.

In some embodiments, the heat exchange system may further include a filter, which may be provided on the first circulation pipe 100 and/or the second circulation pipe 1010 to effectively filter impurities in the pipe. For example, the first and second circulation pipes 100 and 1010 may be provided with first and second filters f1 and f2, respectively, which are disposed at positions as shown in fig. 2. However, the present application is not limited thereto, and one skilled in the art may set filters with different filtering levels according to the requirements, and may set the filters at different positions from fig. 2.

Based on the above configuration, the present application has provided an excellent heat exchange apparatus 1 which can be operated continuously efficiently and stably. In the following, the present application is also improved with respect to the heat dissipating door 2A of the cabinet 2, so that the heat dissipating door 2A can more effectively conduct the heat generated by the server to the outside.

It should be noted that the above description is functional to distinguish between the relationships between the different elements. That is, the foregoing description is only for the purpose of understanding the present application and should not be construed as limiting the application. Please refer to fig. 4, which is another schematic diagram of a heat exchange system according to an embodiment of the present application. In some embodiments, the control module 13 in the heat exchange apparatus 1 may be disposed in the cabinet 2 and defined as a water-to-water stand-alone built-in cooling distribution station CDU (cooling distribution unit). That is, if the present application is described in terms of physical structure or appearance, the heat exchange system of the present application can be substantially regarded as being composed of the ice water machine 1011, the cooling distribution unit CDU, and the cabinet 2. Further, the ice water machine 1011 is installed on the roof of the building. The cooling distribution unit CDU is disposed in the cabinet 2 and performs optimized heat dissipation for the cabinet 2. In addition, when a plurality of cabinets 2 exist, the cooling distribution units CDU in the plurality of cabinets 2 may share one ice water machine 1011.

Please refer to fig. 5 and 6, which are a schematic diagram and an exploded view of a cabinet according to an embodiment of the application. As shown, the heat sink door 2A includes a heat sink coil assembly 20, a plurality of heat sinks 21, and a first plate 22.

In some embodiments, the first plate 22 may be a flat door panel with a plurality of fins 21 and heat dissipating coil assemblies 20 disposed thereon. However, the present application is not limited thereto. In some embodiments, the first plate 22 may also be concavely provided with a receiving space AS, and the plurality of fins 21, the heat dissipation coil assembly 20 and other components mentioned later are disposed in the receiving space AS.

In some embodiments, the heat-dissipating door panel 2A may further include a second plate 23, where the second plate 23 is located between the cabinet main body 2B and the first plate 22 (as shown in fig. 6). An accommodating space AS is formed between the second plate body 23 and the first plate body 22, and the heat dissipation coil assembly 20 and the plurality of heat dissipation fins 21 are disposed in the accommodating space AS. The first plate 22 and the second plate 23 cover the heat dissipation coil assembly 20 and the plurality of heat dissipation fins 21, so that the heat dissipation assemblies can be effectively protected, and the service life of the device can be prolonged.

It should be noted that the heat dissipating door panel 2A of the present application is composed of a door panel for carrying heat dissipating components (e.g., the heat dissipating fins 21 and the heat dissipating coil assembly 20, etc.) and the heat dissipating components therein. Accordingly, door panels known to those skilled in the art (e.g., the first panel 22 or a combination of the first panel 22 and the second panel 23 mentioned above) can be used in the present application. Hereinafter, the heat dissipation door panel 2A including the first plate 22 and the second plate 23 will be described as an example, but the application is not limited thereto.

The plurality of heat dissipation fins 21 are provided on a side of the first plate body 22 adjacent to the cabinet main body 2B, and each of the plurality of heat dissipation fins 21 has a heat dissipation surface 210. More specifically, each heat sink 21 has two heat dissipation surfaces 210 corresponding to each other, and the distance between the two heat dissipation surfaces 210 is the thickness T of the heat sink 21. The thickness T of the heat sink 21 may be determined according to practical requirements. When the thickness T of the heat sink 21 is large, the heat capacity of the heat sink 21 increases, and the heat dissipation effect can be improved. Conversely, when the thickness T of the heat sink 21 is smaller, the volume occupied by the heat sink 21 decreases, so that more heat sinks 21 can be accommodated in the heat radiation door panel 2A.

In some embodiments, the length of each heat sink 21 in the vertical direction is the height H of the heat sink 21. The height H of the heat sink 21 may be determined according to practical requirements. When the height H of the heat sink 21 is large, the heat capacity of the heat sink 21 increases, and the heat dissipation effect can be improved. It should be noted that the height H of the heat sink 21 is preferably less than or equal to the length of the first plate 22 in the vertical direction, so as to avoid exposure of the first plate 22.

In some embodiments, the length of each heat sink 21 in the direction away from the first plate 22 is the width W of the heat sink 21. The width W of the heat sink 21 may be determined according to practical requirements. When the width W of the heat sink 21 is large, the heat capacity of the heat sink 21 increases, and the heat dissipation effect can be improved. It should be noted that, when the heat dissipating door 2A has both the first plate 22 and the second plate 23, the width W of the heat dissipating fin 21 is smaller than or equal to the distance between the inner side surface (the surface far from the external environment) of the first plate 22 and the inner side surface (the surface far from the cabinet body 2B) of the second plate 23.

In some embodiments, the plurality of heat dissipation fins 21 are orthogonal to the inner side surface of the first plate 22, and are sequentially arranged on the first plate 22 along the horizontal direction. In addition, the plurality of fins 21 may be orthogonal to the ground. It should be noted that the term "orthogonal" as used herein refers to the fact that two components (e.g., the plurality of fins 21 and the first plate 22) are substantially perpendicular to each other, which covers the unexpected situation that the two components have a slight angle (e.g., 0.1 to 5 degrees) due to tolerance or assembly process.

In some embodiments, the plurality of heat dissipation fins 21 may be disposed at a specific angle different from 0 degrees with respect to the inner side surface of the first plate 22, and/or the plurality of heat dissipation fins 21 may be sequentially arranged on the first plate 22 along a specific direction different from the horizontal direction. By providing a plurality of heat radiating fins 21 at a specific angle and/or in a specific direction, the heat radiating door panel 2A of the present application can have a more versatile configuration to be applied to different types, different shapes, different sizes of cabinet main bodies 2B and achieve the same excellent heat radiating effect. It should be noted that the plurality of fins 21 may have two or more specific angles or two or more specific directions at the same time, and should not be limited to one specific angle or one specific direction.

In some embodiments, two adjacent fins 21 may have a certain separation distance D therebetween. Wherein the spacing distance D between each group of two adjacent fins 21 may be the same or different. In the present application, the term "separation distance D" refers to a distance between one side surface of the heat sink 21 and the side surface of the same side of the adjacent heat sink 21. For example, the separation distance D between each set of two adjacent fins 21 may be a first length. By setting the spacing distance D between each set of adjacent two fins 21 to be the same, it is possible to make the cabinet main body 2B not have a significant temperature gradient in the horizontal direction. However, the present application is not limited to the above-described manner.

In other embodiments, when more Central Processing Units (CPUs) are stacked in the central area of the cabinet body 2B, the spacing distance D between each two adjacent heat dissipation fins 21 of each set of the present application may be one of the first length or the second length. Wherein the first length is less than the second length. Further, the spacing distance D between the adjacent two fins 21 located in the central area of the first plate body 22 is a first length, and the spacing distance D between the adjacent two fins 21 located in the peripheral area of the first plate body 22 is a second length. In this way, by providing the fins 21 having a higher density in the central area, the heat dissipation effect of the central area of the first plate 22 can be effectively enhanced.

In some embodiments, the plurality of fins 21 may be secured to the inner side surface of the first plate 22 by gluing, interlocking, locking, etc. as is well known to those skilled in the art. For example, the inner surface of the first plate 22 may be concavely provided with a plurality of engaging grooves, and the thickness T of the engaging grooves may be similar to (for example, the same as or slightly smaller than) the thickness T of the heat sink 21. The heat sink 21 can be stably fixed on the first plate 22 by means of clamping or interference fit. It should be noted that the above manner is merely an example, and other arrangements may be adopted or the two arrangements may be combined to obtain a more excellent fixing effect.

In some embodiments, when the heat dissipating door 2A has the first plate 22 and the second plate 23 at the same time, the plurality of heat dissipating fins 21 may be fixed to the first plate 22 and the second plate 23 at the same time by the above-mentioned method or other suitable method, so as to obtain an excellent fixing effect. For example, the plurality of heat sinks 21 may be connected to the first plate 22 and the second plate 23 by fastening. Alternatively, the plurality of heat dissipation fins 21 may be connected to the first plate 22 by fastening, and connected to the second plate 23 by bonding.

In some embodiments, a thermally conductive coating may be provided on the plurality of fins 21. For example, pure metal, alloy, ceramic, or composite materials including the above materials, or other suitable materials with good heat conduction can be disposed on the heat dissipation surface 210 of the plurality of heat dissipation fins 21 by electroplating, sputtering, vapor deposition, coating, etc. to further improve the heat conduction effect of the plurality of heat dissipation fins 21.

Referring to fig. 6 and 7, fig. 7 is a schematic diagram of a fluid path according to an embodiment of the application. As shown, the heat-dissipating coil assembly 20 is disposed on a side of the first plate 22 adjacent to the cabinet body 2B, and the heat-dissipating coil assembly 20 includes a water inlet 200, a water outlet 201, and a plurality of heat-dissipating coils 202. One end of the water inlet 200 is in fluid communication with the first circulation tube 100. One end of the water outlet 201 is in fluid communication with the first circulation tube 100.

In the present application, the positions of the water outlet 201 and the water inlet 200 may be determined according to the position of the heat radiation door panel 2A. In order to reduce the length/volume of the first circulation tube 100 in the heat exchange system, the water outlet 201 and the water inlet 200 are preferably provided at one side of the heat radiation door panel 2A adjacent to the ceiling or the floor so that the first circulation tube 100 disposed along the ceiling or the floor in the heat exchange system may be as close to the water outlet 201 and the water inlet 200 as possible.

In some embodiments, when the first circulation tube 100 is disposed along the ground, the water outlet 201 and the water inlet 200 are located at a side of the first plate 22 adjacent to the ground. More specifically, the openings of the water outlet 201 and the water inlet 200 may be orthogonal to the ground. By disposing the water outlet 201 and the water inlet 200 adjacent to and orthogonal to the ground, the total length of the first circulation tube 100 connected to the heat radiating coil assembly 20 can be effectively reduced. Based on the above configuration, the present application can further improve the space utilization of the whole device.

In some embodiments, when the first circulation tube 100 is disposed along the ceiling, the water outlet 201 and the water inlet 200 are located at a side of the first plate 22 remote from the ground. More specifically, the openings of the water outlet 201 and the water inlet 200 may be adjacent to the ceiling of the machine room to effectively reduce the total length of the first circulation tube 100 connected to the heat radiating coil assembly 20.

Two ends of each of the plurality of heat dissipating coils 202 are respectively in fluid communication with the water inlet 200 and the water outlet 201, and each of the plurality of heat dissipating coils 202 has a plurality of extension sections 2020 and at least one connection section 2021, wherein the plurality of extension sections 2020 sequentially penetrate through the plurality of heat dissipating surfaces 210, and the at least one connection section 2021 is connected to one end of two adjacent ones of the plurality of extension sections 2020 on the same side. More specifically, the number of the plurality of extension sections 2020 may be N, and the number of the connection sections 2021 may be N-1. For example, the number of the plurality of extension sections 2020 may be 3, and the number of the connection sections 2021 may be 2. Alternatively, the number of the plurality of extension sections 2020 may be 5, and the number of the connection sections 2021 may be 4.

In some embodiments, the heat dissipation surface 210 is orthogonal to the plurality of extension segments 2020. In other words, the plurality of extension segments 2020 each subtend an angle of 90 degrees with the heat dissipation surface 210. However, the present application is not limited thereto. In other embodiments, the plurality of extension segments 2020 may each be angled at a specific angle other than 90 degrees with respect to the heat dissipation surface 210.

In some embodiments, the plurality of fins 21 directly contact the plurality of cooling coils 202. In the case where the plurality of fins 21 and the plurality of heat radiating coils 202 are in contact with each other, the rate of heat conduction can be made faster. In some embodiments, each fin 21 may be provided with a plurality of perforations 211 in advance, each perforation 211 corresponding to one extension 2020 in the heat dissipating coil 202. Further, the peripheral edge of the through hole 211 and the extension 2020 are in contact with each other, and the contact area between the heat sink 21 and the extension 2020 is proportional to the thickness T of the heat sink 21 (i.e. the thickness of the peripheral edge). Therefore, by increasing the thickness T of the fin 21 to increase the area of the peripheral edge of the through hole 211 that contacts each other with the extension 2020, the heat conduction rate can be more effectively increased.

In some embodiments, the plurality of heat dissipating coils 202 are disposed on the first plate 22 sequentially along the vertical direction. By providing a plurality of heat radiating coils 202 in sequence, the heat radiating door panel 2A can be divided into a plurality of heat radiating sections B. When more heat dissipation sections B are formed, the temperature of the entire heat dissipation door panel 2A may exhibit frequent periodic changes. For example, it presents: low temperature (the extension 2020 of the first cooling coil 202 near the water inlet 200), medium temperature (the extension 2020 of the first cooling coil 202 near the water outlet 201), low temperature (the extension 2020 of the second cooling coil 202 near the water inlet 200), medium temperature (the extension 2020 of the second cooling coil 202 near the water outlet 201) ….

In contrast, the entire heat-dissipating door panel 2A of the prior art has only one heat-dissipating section B, which generates a significant temperature gradient. For example, it presents: low temperature (extension 2020 of the cooling coil 202 near the water inlet 200), medium temperature (extension 2020 of the cooling coil 202 near the water inlet 200), high temperature (extension 2020 of the cooling coil 202 near the water outlet 201), and ultra high temperature (extension 2020 of the cooling coil 202 near the water outlet 201). In contrast, the heat radiation door panel 2A having the plurality of heat radiation sections B of the present application can effectively alleviate the significant temperature gradient.

As shown in fig. 6, in some embodiments, the heat radiation door panel 2A further includes a plurality of fans 24, and the plurality of fans 24 are disposed between the heat radiation fins 21 and the cabinet main body 2B and correspond to the plurality of heat radiation fins 21. That is, a plurality of fans 24 may be provided in the interior of the cabinet 2. Specifically, the fan 24 is configured to suck the hot air inside the cabinet main body 2B out of the heat radiation door panel 2A. In this way, the hot air in the cabinet 2 is cooled while passing through the heat dissipating coil 202 and the heat dissipating fins 21, and leaves the heat dissipating door 2A at a low temperature. Further, the gas outside the heat radiation door panel 2A is pushed to move in a direction away from the heat radiation door panel 2A. In addition, after the air in the cabinet 2 leaves from the heat-dissipating door 2A and moves in a direction away from the heat-dissipating door 2A, the air in the external environment can enter into the cabinet body 2B from the side of the cabinet body 2B away from the heat-dissipating door 2A, so as to form a good heat-dissipating cycle.

In some embodiments, the plurality of fans 24 are disposed outside the first plate 22 and correspond to the plurality of heat sinks 21. That is, the fans 24 may be externally hung on the cabinet 2. In other embodiments, a plurality of fans 24 may be disposed between the heat sink 21 and the cabinet body 2B and outside the first plate 22 at the same time, so as to obtain a better air suction effect. The operation of the fans 24 is similar or identical to that described above, and will not be repeated here.

In some embodiments, when the heat dissipating door panel 2A of the cabinet 2 further includes a plurality of fans 24, the first plate 22 and the second plate 23 have a plurality of air holes, respectively. By providing the air holes, the hot air in the cabinet 2 is more easily carried by the fan 24 and leaves the cabinet 2 by the heat radiation door panel 2A. In some embodiments, the plurality of air holes are spaced apart from each other by a fixed distance in order to improve stability of the intake air. In some embodiments, the plurality of air holes are spaced apart from each other by different distances in order to enhance the local heat dissipation effect. For example, the area where the heat dissipation effect needs to be improved may correspond to more air holes.

In some embodiments, the heat-dissipating door panel 2A of the cabinet 2 further includes a roller 25, and the roller 25 is disposed on a side of the first plate 22 adjacent to the ground. Since a large number of heat radiating components such as the heat radiating coil 202, the heat radiating fins 21 are provided in the heat radiating door panel 2A of the present application, it is necessary to have a certain weight. Therefore, by providing the roller 25, the heat radiation door panel 2A of the present application can be easily opened or closed. It should be noted that although one roller 25 is shown in the drawings of the present application, the present application is not limited thereto. In other embodiments, the number of the rollers 25 may be two, three or more than three, which may be determined according to actual use.

In summary, the heat exchange system conducts the heat in the cabinet out through the first circulation pipe and conducts the heat to the ice water machine through the second circulation pipe, so that the heat is effectively dissipated. Wherein only heat is transferred between the first circulation tube and the second circulation tube, and not in fluid communication. Therefore, the second fluid flowing between the second circulating pipe and the ice water machine can not pollute the first fluid flowing between the first circulating pipe and the cabinet, so that the service life of the whole heat exchange system is effectively prolonged. Therefore, the application realizes the heat exchange system which can effectively dissipate heat and can continuously and stably run.
