Example 1

1, 2 and 3, an embodiment of the present application provides a cold storage and cold supply system for a cold storage 10, including:

Refrigeration equipment 100, used to provide cold storage 10;

A temperature sensor 500, which is connected to the control device 200 by signal; used to collect the real-time temperature in the cold storage;

A control device 200, the control device 200 is electrically connected to the refrigeration device 100, and is configured to control the refrigeration device 100 to provide a first cooling capacity during the peak power period based on the real-time temperature during the peak power period, to control the refrigeration device 100 to provide a second cooling capacity during the valley power period based on the real-time temperature during the valley power period, and to control the refrigeration device 100 to provide a third cooling capacity during the valley power period based on the real-time temperature during the normal power period; wherein the first cooling capacity is less than the third cooling capacity, and the third cooling capacity is less than the second cooling capacity;

A cold storage module 300 is disposed in the cold storage 10; the cold storage module 300 includes a support assembly and a plurality of cold storage boxes 310; a plurality of the cold storage boxes 310 are mounted on the support assembly; each of the cold storage boxes 310 is filled with a phase change material; wherein the phase change material provides cold air to the cold storage 10 during the peak power period and stores cold air during the valley power period.

In the technical solution of the embodiment of the present application, a cold storage module 300 is arranged in the cold storage 10 , and the cold storage module 300 includes a plurality of cold storage boxes 310 ; the cold storage boxes 310 are filled with phase change materials. By controlling the real-time temperature of the control device 200 during the peak power, valley power and flat power periods, the refrigeration device 100 operates with different cooling capacities during the peak power, valley power and flat power periods; wherein, the cooling capacity corresponding to the peak power is the smallest, and the cooling capacity corresponding to the valley power is the largest; when the refrigeration device 100 operates to provide a larger second cooling capacity during the valley power period, while maintaining the low temperature environment of the cold storage 10, the excess cooling capacity is absorbed by the phase change material to store cold, and the cold storage 10 enters the cold storage mode for maintaining the low temperature environment; when the refrigeration device 100 operates to provide a third cooling capacity less than the second cooling capacity during the flat power period, the cooling capacity provided by the refrigeration device 100 decreases, and the cold storage 10 enters the maintenance mode for maintaining the low temperature environment; when the refrigeration device 100 operates with a smaller cooling capacity or provides 0 cooling capacity during the peak power period, the phase change material can release cooling capacity to the cold storage 10, and the cold storage 10 enters the cold release mode for maintaining the low temperature environment. Therefore, the technical solution provided by the embodiment of the present application can control the peak power consumption of the cold storage 10, reduce power loss, improve the utilization rate of the cooling capacity provided by the refrigeration device 100, and achieve energy conservation and emission reduction.

In the implementation of this application, the cold storage and cooling system also includes a management device 700, which is signal-connected to the control device 200; the management device 700 is used to obtain the temperature of the cold storage 10 and/or the operating parameters of the refrigeration device 100 through the control device 200.

In an embodiment, the management device 700 may be a PC terminal, an APP applet, etc. The manager may obtain the temperature of the cold storage 10 and/or the operating parameters of the refrigeration device 100 by operating the management device 700. The control device 200 has a memory for storing operating parameter data of the refrigeration device 100, the temperature of the cold storage 10 and other parameters. The operating parameters of the refrigeration device 100 mainly include: the start and shut down time of the refrigeration device 100, the adjustment history of the operating parameters of the refrigeration device 100, the speed of the compressor and the speed of the fan in the refrigeration device 100, the power consumption of the refrigeration device 100, the electricity fee, the power saving ratio, etc. The temperature of the cold storage 10 includes the real-time temperature, the temperature change, etc.

Generally, the refrigeration device 100 includes a refrigerator and a fan. The refrigerator includes a compressor, a heat exchanger, a throttle valve and a pipeline. The refrigerator generates cold air under the action of the compressor, the heat exchanger and the throttle valve. The fan is generally arranged on the wall of the cold storage 10 to send the cold air into the cold storage 10 to provide cold capacity in the cold storage 10.

In the embodiment, the control device 200 adjusts the cooling capacity of the refrigeration device 100 during peak power, valley power and flat power periods by controlling the speed of the fan and the speed of the compressor. For example, during peak power, the fan and the compressor can stop running, and the speed of the fan and the speed of the compressor can be 0; of course, the speed of the fan and the speed of the compressor can run at a lower speed respectively. During flat power, the speed of the fan and the compressor can be increased relative to the peak power to provide cooling. The cold storage 10 provides a certain amount of cooling capacity. During off-peak hours, the speed of the fan and the compressor can be further increased relative to the off-peak hours to provide sufficient cooling capacity for the cold storage 10.

It should be noted that after the cold storage 10 enters the stable operation stage, the fan and the compressor are shut down during the peak power period or the shutdown time is long enough to reduce the power consumption during the peak power period and reduce the pressure on the power grid. The fan and the compressor can run at a sufficiently large speed during the valley power period to provide sufficient cooling capacity to the cold storage 10 during the valley power period, so that the phase change material can accumulate cooling capacity to maintain the low temperature environment of the cold storage 10 during the peak power period. The fan and the compressor run at the smallest possible speed during the flat power period to provide the cold storage 10 with cooling capacity to maintain its low temperature.

Further, it should be noted that the control device 200 includes at least one processor, at least one memory, and a control program of the cold storage and cooling system stored in the memory and executable on the processor, and the control program of the cold storage and cooling system is configured to implement the steps of the control method as described above. As shown in FIG18 , the control method specifically includes:

S100, based on the real-time temperature during the peak power period, controlling the refrigeration device 100 to provide a first refrigeration capacity during the peak power period;

S200, based on the real-time temperature during the off-peak period, controlling the refrigeration device 100 to provide a second refrigeration capacity during the off-peak period;

S300, based on the real-time temperature during the flat-time period, controlling the refrigeration device 100 to provide a third cooling capacity during the flat-time period; wherein the first cooling capacity is smaller than the third cooling capacity, and the third cooling capacity is smaller than the second cooling capacity.

In the embodiment, a temperature to be maintained is set in the cold storage; the real-time temperature and the maintained temperature in different time periods are compared to control the refrigeration capacity provided by the refrigeration device 100 in different time periods.

The processor may include one or more processing cores, such as a 4-core processor, an 8-core processor, etc. The memory may include one or more computer-readable storage media, which may be non-transitory. The memory may also include a high-speed random access memory, and a non-volatile memory, such as one or more disk storage devices, flash memory storage devices. In some embodiments, the non-transitory computer-readable storage medium in the memory is used to store at least one instruction, which is used to be executed by the processor to implement the control method of the cold storage and cooling system provided in the method embodiment of the present application.

It should be noted that the cold storage box 310 of the embodiment of the present application can be made of HDPE material or metal material. Phase change material is a commonly used material in this field. When the cold storage box 310 is made of HDPE material, the phase change material can be a phase change material with a phase change point between -70°C and 50°C. When the cold storage box 310 is made of metal material, the phase change material can have a wider range of phase change points. Generally speaking, in the cold storage 10, the cold storage box 310 is generally made of HDPE material, and the phase change material can be a phase change material with a phase change point between -15°C and 20°C, which can meet the construction of the commonly used cold storage 10. In other different application fields, the material of the cold storage box 310 and the type of phase change material can be specifically set according to the temperature range that needs to be maintained, and no further details will be given here.

In the embodiment, the volume of the phase change material filled in each cold storage box 310 is between 80% and 90% of the internal volume of the cold storage box 310 , preferably 85%.

As an optional implementation of the above embodiment, in combination with FIG. 4 and FIG. 5 , the cold storage box 310 includes a main body 311 and a raised portion 312; the raised portion 312 is protruding from the main body 311 and has an internal cavity; the phase change material is filled in the internal cavity; the main body 311 is provided with a perforation H; the support assembly includes a connector 320, and the connector 320 cooperates with the perforation H. Specifically, the main body 311 has an outer surface; the raised portion 312 is protruding from the outer surface and defines the internal cavity of the cold storage box 310, and the internal cavity is used to fill the phase change material, The main body 311 is provided with a through hole H that is not connected to the internal cavity. In the technical solution of the embodiment of the present application, the raised portion 312 is provided on the outer surface of the main body 311 and is defined for filling the phase change material to improve the cold storage capacity of the cold storage box 310; and the main body 311 is provided with a through hole H that is not connected to the internal cavity, so as to be connected to the external connector 320, so as to facilitate the installation of the cold storage box 310. Therefore, the technical solution of the present application can make the cold storage box 310 have good cold storage capacity and can be installed quickly.

In some specific embodiments, the cold storage box 310 has a length direction and a width direction. There are multiple protrusions 312, and the multiple protrusions 312 extend along the width direction and are arranged at intervals in the length direction; a heat dissipation gap is defined between two adjacent protrusions 312. By arranging the protrusions 312 at intervals to define a heat dissipation gap between the protrusions 312, the heat exchange area is increased to improve the heat exchange efficiency of the cold storage box 310. For example, the first part of the protrusion 312 extends along the width direction and is arranged at intervals in the length direction; and the second part of the protrusion 312 extends along the length direction and is arranged at intervals in the width direction. The two ends of the first part of the protrusion 312 extending along the width direction are connected to the second part of the protrusion 312 extending along the length direction, so that the protrusion 312 defines the internal cavity of the cold storage box 310.

Generally speaking, there are multiple first raised portions 312 extending in the width direction. The number and spacing of the first raised portions 312 are specifically set by the implementer mainly according to the heat exchange capacity required by the cold storage box 310. However, there are two second raised portions 312 extending in the width direction, which are respectively located at the two edges of the cold storage box 310 in the width direction.

In some other embodiments, the outer surface includes a first outer surface and a second outer surface that are arranged opposite to each other in the thickness direction of the cold storage box 310; the raised portion 312 includes a first raised portion and a second raised portion, the first raised portion is arranged protruding from the first outer surface, and the second raised portion is arranged protruding from the second outer surface. In order to increase the cold storage capacity of the cold storage box 310, in the technical solution of the embodiment of the present application, the first raised portion and the second raised portion are respectively arranged on opposite sides of the main body 311 in the thickness direction, and the specific structures of the first raised portion and the second raised portion are arranged with reference to the above embodiment. Generally speaking, the first raised portion and the second raised portion are arranged symmetrically.

Further, as shown in FIG. 4 and FIG. 5 , the cold storage box 310 has a filling port 313, and the filling port 313 is used to fill the phase change material. The filling port 313 is arranged at a corner of the cold storage box 310. In the cold storage module 300, the filling port 313 is arranged on the upper side of the cold storage box 310, which can prevent the phase change material in the cold storage box 310 from leaking. Usually, the filling ports 313 of multiple cold storage boxes 310 are arranged along a linear array, and the filling port 313 is arranged at a corner position of the cold storage box. For example, the cold storage box has multiple corners, and the filling port 313 is arranged at one of the multiple corners. Generally, the cold storage box is roughly square, and the filling port 313 is arranged at any corner of the four corners of the cold storage box. When the cold storage box is assembled into a cold storage module, the filling port 313 is arranged at the upper corner, such as the upper left corner or the upper right corner, to prevent the phase change material from leaking.

As an optional implementation of the above embodiment, the cold storage box also includes a sealing plug, which is embedded in the filling port 313. The cold storage box includes a box body, and the box body includes the main body 311 and the raised portion 312. The sealing plug is welded to the box body by ultrasonic welding, so that the plug body and the cold storage box 310 are welded together to prevent liquid leakage.

In the technical solution of the present application, the cold storage module 300 has a variety of different implementations, see Example 2 and Example 3 for details. Example 2 mainly provides a cold storage module 300 installed on a shelf to be applied in the cold storage and cooling system.

In addition, the implementer can apply the cold storage modules 300 of different structural forms provided in Embodiments 2 and 3 to the cold storage cooling system according to the space size of the cold storage 10, as shown in Embodiment 4 for details.

Example 2

6 to 10 , embodiment 2 provides a layer-net type cold storage module that can be installed on a shelf based on embodiment 1. The layer-net type cold storage module is arranged on a shelf frame 350 in a cold storage 10 when used, so as to facilitate storage of refrigerated goods in the cold storage 10 .

In an embodiment, as shown in Figures 6 and 7, the support assembly also includes: a layer grid shelf 330, the layer grid shelf 330 has a support side S1 for supporting goods; the multiple cold storage boxes 310 are located on the opposite side S2 of the support side S1; wherein the perforation H includes a first perforation H1; and the connecting member 320 is a slender member.

In an embodiment, as shown in FIG8 and FIG9, the connecting member 320 includes a penetration section 321 and a first connecting section 325 and a second connecting section 323 located at both ends of the penetration section 321, the penetration section 321 is penetrated in the perforation H, and the first connecting section 325 and the second connecting section 323 are respectively connected to different positions of the layer network shelf 330. In an embodiment, the penetration section 321 is adapted to the size of the first perforation H1 so as to be able to pass through the first perforation H1. The two ends of the penetration section 321 are the first connecting section 325 and the second connecting section 323, respectively. The first connecting section 325 and the second connecting section 323 are respectively connected to different positions of the layer network shelf 330, and then the cold storage box 310 is set between these two different positions.

In the technical solution of the embodiment of the present application, the connecting member 320 is generally a slender structure, such as a steel wire or a thin rope, etc. Taking the steel wire as an example, the steel wire has a penetration section 321 penetrated through the first through hole H1, and also has a first connection section 325 and a second connection section 323 located at both ends of the penetration section 321 and connected to the layer network shelf 330.

In the technical solution of the present application, the connecting member 320 is passed through the first through hole H1 of the cold storage box 310, connected to the layer grid shelf 330 and has a first connection position and a second connection position, so that the cold storage box 310 is connected to the layer grid shelf 330; the cold storage box 310 is arranged on the opposite side S2 of the supporting side S1 of the layer grid shelf 330; that is: the cold storage box 310 is suspended on the lower side of the layer grid shelf 330 without interfering with the placement of goods; a phase change material is arranged in the cold storage box 310 to release cold energy into the cold storage to maintain the temperature of the cold storage for at least a period of time when the refrigeration system stops or fails, thereby extending the refrigeration time.

In a specific embodiment, as shown in FIG. 7 , the layer net shelf 330 has at least two first rods 331 spaced apart along the thickness direction of the cold storage box 310, and the first connecting section 325 and the second connecting section 323 are respectively connected to the first rods 331 at different positions. In a specific embodiment, a plurality of first rods 331 are spaced apart along the thickness direction of the cold storage box 310 to form the basic structure of the layer net shelf 330. In some embodiments, the layer net shelf 330 further includes a plurality of second rods 332, which are spaced apart along the length direction of the cold storage box 310, and each second rod 332 is connected to the first rod 331 to form a grid structure that can be used to carry goods. The first connecting section 325 and the second connecting section 323 of the connecting member 320 are fixed on the first rods 331 spaced apart after the penetration section 321 is penetrated through the first perforation H1, so that the cold storage box 310 can be hung on the opposite side S2 of the supporting side S1 of the layer net shelf 330.

In the technical solution of the embodiment of the present application, the layer net shelf 330 can be constructed as a standard part, which is convenient for improving the manufacturing efficiency of the layer net shelf 330. Of course, the layer net shelf 330 can also be customized according to the load-bearing requirements and refrigeration requirements. In general, in order to improve the efficiency of installing the cold storage module 300, the connector 320 usually has a plurality of penetration sections 321, a first connection section 325 and a second connection section 323. Taking two adjacent cold storage boxes 310 as the research object, the second connection section 323 corresponding to one cold storage box 310 is connected to the first connection section 325 of the other cold storage box 310. That is: the two adjacent penetration sections 321 in the connector 320 are respectively penetrated in the first perforations H1 of the two adjacent cold storage boxes 310, wherein the first connection section 325 connected to the penetration section 321 penetrated in one of the cold storage boxes 310 is connected to the second connection section 323 connected to the penetration section 321 penetrated in the other cold storage box 310.

Further, as shown in FIG. 9 , the connecting member 320 further includes a first bending section 324 and a second bending section 322, wherein the first bending section 324 and the second bending section 322 are respectively disposed at opposite ends of the penetration section 321. The folded section 324 is connected to the first connecting section 325, and the second bent section 322 is connected to the second connecting section 323; wherein the spacing between the first bent section 324 and the second bent section 322 is greater than the thickness of the cold storage box 310. When installing a group of cold storage units, multiple cold storage boxes 310 can be connected in series through the connector 320. Then, the portion outside the first perforation H1 of the connector 320 is bent twice to form multiple bent sections and multiple connecting sections, respectively. The multiple connecting sections are connected to the layer network shelf 330, and then the group of cold storage units is installed on the layer network shelf 330. The cold storage box 310 is between two adjacent bent sections.

In the technical solution of the present application, since the connecting member 320 is inserted into the first through hole H1, the cold storage box 310 and the connecting member 320 are loosely matched, allowing the cold storage box 310 to move. For a cold storage box 310, it is restricted by the adjacent first bending section 324 and the second bending section 322; therefore, when the cold storage box 310 is allowed to move, its range of movement is restricted by the first bending section 324 and the second bending section 322 to avoid contact with the adjacent cold storage box 310. On the one hand, the adjacent cold storage boxes 310 have an appropriate spacing to facilitate their absorption or release of cold, and on the other hand, it can prevent the cold storage box 310 from being damaged by collision.

It should be further explained that, in order to improve the stability of the cold storage box 310, each cold storage box 310 is usually provided with a plurality of first perforations H1. Generally speaking, the number of connectors 320 is consistent with the number of first perforations H1. For example, if the number of first perforations H1 of the cold storage box 310 is two, then generally speaking, the number of connectors 320 is two. For example, two steel wires are respectively inserted into the first perforations H1 distributed along different axes to connect the cold storage boxes 310 in series.

As an optional implementation of the above embodiment, the layer-net type cold storage module 300 includes at least two groups of cold storage units. Each group of the cold storage units includes a plurality of the cold storage boxes 310, and the plurality of the cold storage boxes 310 are spaced apart along the thickness direction thereof. Generally speaking, the first direction of the layer-net type cold storage module 300 is parallel to the thickness direction of the cold storage box 310 and the axial direction of the first rod 331, and the second direction is parallel to the length direction of the cold storage box 310 and the axial direction of the second rod 332. That is: the cold storage boxes 310 of each group are spaced apart in the axial direction of the first rod 331 to form a group of cold storage units. At least two groups of the cold storage units are spaced apart along the length direction of the cold storage box 310. For example, the layer-net type cold storage module 300 includes two groups of cold storage units. The two groups of cold storage units are spaced apart in the length direction of the cold storage box 310.

In a specific implementation, at least two groups of cold storage units are connected to the same layer-net shelf 330.

11 to 17 , Example 3, based on Example 1, provides a pipe rack type cold storage module that can be installed on the ceiling, side walls, and near the ceiling of the cold storage 10 to facilitate storage of refrigerated goods in the cold storage 10 .

In order to enable the cold storage box to be used in more application scenarios, the cold storage box is generally provided with perforations H of different shapes and/or sizes. As an optional implementation of the above embodiment, the perforation H includes a second perforation H2. The second perforation H2 and the first perforation H1 have different shapes and/or sizes. The implementer can select different perforations H to assemble the cold storage box into different cold storage modules according to the installation position of the cold storage box. In some embodiments, the second perforation H2 is circular.

As an optional implementation of the above embodiment, as shown in Figures 11 and 12, the connecting member 320 includes: a fixed main pipe 326, which is passed through the through hole H of each of the cold storage boxes 310; a plurality of fixed sub-pipes 327, which are sleeved on the fixed main pipe 326, and the opposite ends of each of the fixed sub-pipes 327 abut against two adjacent cold storage boxes 310; and a limiting pipe 328, which is passed through the fixed main pipe 326 and abuts against the outermost cold storage box 310 among the plurality of cold storage boxes 310. In the embodiment, different from the embodiment 2, the technical solution adopted in the present embodiment is to connect a plurality of cold storage boxes 310 in series through a fixed main pipe 326; a fixed auxiliary pipe 327 is sleeved on the fixed main pipe 326 and abuts against two adjacent cold storage boxes 310, so that an appropriate distance is maintained between the cold storage boxes 310, so that the phase change material therein can absorb and release cold energy; a limiting pipe 328 is sleeved on the fixed main pipe and abuts against the outermost cold storage box 310 to relatively fix the cold storage box 310, so as to form the tube rack type energy storage module, so that when in use, the cold storage module 300 can be installed on an external structure to provide cold energy to the environment.

In an embodiment, the fixed main pipe 326 can be made of a glass fiber tube. The fixed auxiliary pipe 327 can be made of a PVC short pipe. The limit pipe 328 can be made of a stainless steel tee with a glass fiber tube. Of course, the implementer can specifically select the materials of the fixed main pipe 326, the fixed auxiliary pipe 327 and the limit pipe 328 according to the specific application environment, and no further examples are given here. The two axial end faces of each of the fixed auxiliary pipes 327 are respectively abutted against the main body 311 of the two adjacent cold storage boxes 310. In an embodiment, the outer diameter of the fixed auxiliary pipe 327 is greater than the fixed diameter, so that the fixed auxiliary pipe 327 abuts against the main body 311 of the cold storage box 310 when it is sleeved on the fixed main pipe 326, thereby separating the multiple cold storage boxes 310. The opposite sides of the main body 311 of the cold storage box 310 located in the middle are respectively abutted by two adjacent fixed auxiliary pipes 327.

As an optional implementation of the above embodiment, in order to improve the stability of the cold storage box 310 installed as the cold storage module 300; each of the cold storage boxes 310 has at least two second perforations H2. The at least two second perforations H2 are generally arranged to be spaced apart in the length direction of the cold storage box 310. The number of the fixed main pipes 326 is consistent with the number of the second perforations H2, and the fixed main pipes 326 match the second perforations H2 one by one.

For example, in the embodiment, each cold storage box 310 has two second through holes H2, and the fixed main pipes 326 have two. In the same cold storage box 310, the two fixed main pipes 326 are respectively inserted into different second through holes H2. During assembly, the two second through holes H2 on one cold storage box 310 are first matched with the two fixed main pipes 326, and then the two fixed sub-pipes 327 are sequentially sleeved on the sleeved fixed main pipes 326, and then the next cold storage box 310 is assembled; the above steps are executed cyclically to complete the assembly of the cold storage box 310.

As an optional implementation of the above embodiment, the limiting pipe 328 includes a first pipe joint, a cross pipe, and a second pipe joint. The first pipe joint is connected to the second pipe joint through the cross pipe. The joints are respectively sleeved on different fixed main pipes 326 and abut against the outermost cold storage box 310 among the plurality of cold storage boxes 310. Generally speaking, the first pipe joint and the second pipe joint are both three-way structures. The two ends of the horizontal pipe are respectively inserted into the first pipe joint and the second pipe joint. The first pipe joint and the second pipe joint abut against the outermost cold storage box 310, thereby preventing the cold storage box 310 from slipping out.

In the embodiment, since the cold storage module 300 has two cold storage boxes 310 located at the outermost sides, the cold storage module 300 generally has two limit tubes 328 to limit the cold storage boxes 310 from sliding out from both ends of the fixed main tube 326 .

In some embodiments, when the number of the fixed main pipe 326 is one, the limiting pipe 328 can be set only as a limiting pipe head; a limiting pipe head is respectively provided at both ends of the fixed main pipe 326 to limit the axial movement of the cold storage box 120.

As an optional implementation of the above embodiment, the fixed main pipe 326 and the second through hole H2 have a clearance fit or a transition fit. In the embodiment, the fixed main pipe 326 and the second through hole H2 have a clearance fit or a transition fit, which is conducive to the disassembly and assembly of the fixed main pipe 326 and the cold storage box 310.

In an embodiment, a part of the plurality of protrusions 312 is a load-bearing protrusion 3121, and another part is a heat dissipation protrusion 3122. In the width direction of the cold storage box 310, the size of the plurality of load-bearing protrusions 3121 is smaller than the size of the plurality of heat dissipation protrusions 3122. That is, the extension length of the load-bearing protrusion 3121 in the width direction is smaller than the extension length of the heat dissipation protrusion 3122 in the width direction. Among them, the load-bearing protrusion 3121 is arranged around the second perforation H2. In assembling the cold storage box 310 into a tube rack type cold storage module, the second perforation H2 cooperates with the fixed main pipe 326. The area where the second perforation H2 is located is subjected to assembly force. Therefore, in order to improve the assembly capacity of the cold storage box 310, a part of the protrusion 312 near the second perforation H2 (the load-bearing protrusion 3121) is designed to be reduced in the extension length in the width direction, and its strength is increased to have a reinforcing effect, thereby improving the load-bearing capacity of the cold storage box 310.

The extension length of the protrusion 312 around the second through hole H2 is reduced to form four bearing protrusions 3121 ; the four bearing protrusions 3121 are shorter than the heat dissipation protrusions 3122 and are arranged around the second through hole H2 .

As an optional implementation of the above embodiment, the perforation H is arranged corresponding to the heat dissipation gap. For example, in a projection plane perpendicular to the thickness direction, the perforation H is located in the interval between the protrusions 312. For another example, the first perforation H1 is located in the interval area between the bearing protrusion 3121 and the heat dissipation protrusion 3122; the second perforation H2 is located in the interval area defined by the bearing protrusion 3121.
