Description

Technical Field

[0001] This invention relates to the field of server heat dissipation technology, and more specifically to a cooling system for an integrated heat pipe cooling cabinet. Background Technology

[0002] Currently, servers are installed in racks, which are located in computer rooms. During operation, servers generate a lot of heat. In related technologies, to avoid localized overheating in the racks, air conditioning equipment is usually used to cool the servers at high power consumption, which results in energy waste. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, this invention proposes a cooling system for an integrated heat pipe cooling cabinet.

[0005] In view of this, a first aspect of the present invention provides a cooling system for a heat pipe cooling integrated cabinet for a server. The cooling system includes a first cabinet, a first heat exchange component, at least two second heat exchange components, and a third heat exchange component. The first cabinet is used to install the server; the first heat exchange component is disposed inside the first cabinet and located on a first side of the first cabinet in the height direction; at least two second heat exchange components are disposed along the height direction of the first cabinet and located on both sides of the first cabinet in the length direction; the third heat exchange component is located outside the first cabinet, and the drain end of the third heat exchange component is connected to one end of the first heat exchange component and one end of the at least two second heat exchange components, respectively, and the inlet end of the third heat exchange component is connected to the other end of the first heat exchange component and the other end of the at least two second heat exchange components, respectively; wherein a first medium can flow between the first heat exchange component, the at least two second heat exchange components, and the third heat exchange component.

[0006] In this technical solution, the cooling system of the integrated heat pipe cooling cabinet is used for the server, thereby dissipating heat from the server. The cooling system of the integrated heat pipe cooling cabinet includes a first cabinet, a first heat exchange component, at least two second heat exchange components, and a third heat exchange component. The first cabinet is used to install the server. The first heat exchange component is located within the first cabinet, on the first side of the first cabinet in the height direction. That is, after the server is installed in the first cabinet, the first heat exchange component is located on one side of the server, close to the server for cooling, so that the first heat exchange component can absorb the heat generated by the server and avoid localized hot spots within the first cabinet. The at least two second heat exchange components are arranged along the height direction of the first cabinet, located on both sides of the first cabinet in the length direction. The at least two second heat exchange components can be located on both sides of the server along the length direction of the first cabinet, thereby absorbing the heat dissipated by the server and further dissipating heat from the server. The third heat exchange component is located outside the first cabinet. Its drain end is connected to one end of the first heat exchange component and one end of at least two second heat exchange components. Its inlet end is connected to the other end of the first heat exchange component and the other end of at least two second heat exchange components, thus establishing communication between the first, at least two, and third heat exchange components. A first medium can flow between these components, allowing it to absorb heat generated by the server within the first and at least two second heat exchange components. After absorbing heat and evaporating, the medium can flow into the third heat exchange component and condense into a low-temperature liquid form. After condensation in the third heat exchange component, the medium can flow back into the first and at least two second heat exchange components to continue evaporating and absorbing heat. This circulating flow of the first medium enables cyclical heat exchange for the server. By setting a first heat exchange component, at least two second heat exchange components, and a third heat exchange component on the first cabinet, the server can be directly cooled, avoiding the generation of local hot spots. Compared with using air conditioning equipment to cool the server with high power consumption, this method not only avoids the generation of local hot spots, but also avoids energy waste because it eliminates the need to use air conditioning equipment to cool the server with high power consumption, thereby improving the heat dissipation efficiency of the server.

[0007] In addition, the cooling system of the heat pipe cooling integrated cabinet in the above-mentioned technical solution provided by the present invention may also have the following additional technical features:

[0008] In some technical solutions of the present invention, optionally, at least two second heat exchange components include a first sub-heat exchanger and a second sub-heat exchanger. The first sub-heat exchanger is located on a first side of the first cabinet in the length direction and is connected to the first cabinet; the second sub-heat exchanger is located on a second side of the first cabinet in the length direction and is connected to the first cabinet.

[0009] In this technical solution, at least two second heat exchange components include a first sub-heat exchanger and a second sub-heat exchanger. The first sub-heat exchanger is located on a first side of the first cabinet along its length and is connected to the first cabinet to enable installation of the first cabinet and improve the stability of the first cabinet after installation. The second sub-heat exchanger is located on a second side of the first cabinet along its length and is connected to the first cabinet to enable installation of the first cabinet and improve the stability of the second cabinet after installation. By setting up the first and second sub-heat exchangers, heat dissipated from the server to the outside of the first cabinet can be cooled.

[0010] Optionally, in some technical solutions of the present invention, the first heat exchange component includes a first heat exchange tube, which is located on one side of the server along the length of the first cabinet.

[0011] In this technical solution, the first heat exchange component includes a first heat exchange tube, which is located on one side of the server along the length of the first cabinet to realize the installation of the first heat exchange tube, thereby cooling the server through the heat exchange tube, which can increase the heat dissipation area and improve the heat exchange efficiency.

[0012] In some technical solutions of the present invention, optionally, the installation direction of the first heat exchange tube is the same as the installation direction of the server.

[0013] In this technical solution, the installation direction of the first heat exchanger tube is the same as that of the server, ensuring that the server and the first heat exchanger tube are arranged in parallel after installation. This facilitates the installation of both the server and the first heat exchanger tube and avoids interference between them during installation. The parallel arrangement also ensures that the first heat exchanger tube provides uniform heat dissipation to the server from all locations.

[0014] Optionally, in some technical solutions of the present invention, the third heat exchange assembly includes a first inlet pipe, a first outlet pipe, and a first condenser. One end of the first inlet pipe is connected to the outlet of the first heat exchange assembly and the outlets of at least two second heat exchange assemblies; one end of the first outlet pipe is connected to the inlet of the first heat exchange assembly and the inlet of at least two second heat exchange assemblies; one end of the first condenser is connected to the other end of the first inlet pipe, and the other end of the first condenser is connected to the other end of the first outlet pipe.

[0015] In this technical solution, the third heat exchange component includes a first inlet pipe, a first outlet pipe, and a first condenser. One end of the first inlet pipe is connected to the outlet of the first heat exchange component and the outlets of at least two second heat exchange components, thereby connecting the first inlet pipe to the first and second heat exchange components. One end of the first outlet pipe is connected to the inlet of the first heat exchange component and the inlet of at least two second heat exchange components, thereby connecting the first outlet pipe to the first and second heat exchange components. One end of the first condenser is connected to the other end of the first inlet pipe, and the other end of the first condenser is connected to the other end of the first outlet pipe. By connecting the first inlet pipe and the first outlet pipe through the first condenser, the first condenser can condense the high-temperature gaseous first medium after heat exchange in the first heat exchange component and at least two second heat exchange components. After condensation in the first condenser, the first medium can flow back into the first and at least two second heat exchange components under the action of gravity to continue heat exchange, thereby achieving cyclic heat dissipation for the server and improving heat dissipation efficiency.

[0016] Optionally, in some technical solutions of the present invention, the third heat exchange component further includes a first heat exchanger, which is arranged in parallel with the first drain pipe and is capable of exchanging heat with the first medium in the first drain pipe.

[0017] In this technical solution, by setting the first heat exchanger and the first drain pipe side by side, the first heat exchanger can exchange heat with the first medium inside the first drain pipe. This allows the first heat exchanger to lower the temperature of the first medium inside the first drain pipe, ensuring that the first medium is completely cooled before entering the second pipeline and the second heat exchange assembly to dissipate heat from the server, thus ensuring the stability of server cooling. By using the first heat exchanger to supplement the cooling of the first medium inside the first drain pipe, the first medium inside the first drain pipe can be completely cooled even when the outside temperature of the computer room is high.

[0018] In some technical solutions of the present invention, optionally, the first heat exchanger includes a second condenser, a compressor, an expansion valve, and a first evaporator. One end of the compressor is connected to one end of the second condenser; one end of the expansion valve is connected to the other end of the second condenser; the first evaporator is located near the first drain pipe, one end of the first evaporator is connected to one end of the expansion valve, and the other end of the first evaporator is connected to the other end of the compressor; the second medium can flow between the compressor, the second condenser, the expansion valve, and the first evaporator.

[0019] In this technical solution, the third heat exchanger includes a second condenser, a compressor, an expansion valve, and a first evaporator. One end of the compressor is connected to one end of the second condenser; one end of the expansion valve is connected to the other end of the second condenser; one end of the first evaporator is connected to one end of the expansion valve, and the other end of the first evaporator is connected to the other end of the compressor, thus connecting the compressor, the second condenser, the expansion valve, and the first evaporator. This allows the second medium to flow between the compressor, the second condenser, the expansion valve, and the first evaporator. The low-pressure second medium is compressed into a high-temperature, high-pressure gas by the compressor, then condensed into a high-pressure liquid in the second condenser. After being throttled into a low-pressure liquid by the expansion valve, it evaporates and absorbs heat in the first evaporator. Since the first evaporator is located close to the first drain pipe, the evaporation and heat absorption process of the second medium in the first evaporator can cool the first medium in the first drain pipe, thus providing supplemental cooling for the first medium and ensuring the stability of the server's heat dissipation.

[0020] In some technical solutions of the present invention, optionally, the third heat exchange assembly further includes a second inlet pipe, a first switching valve, and a second switching valve. One end of the second inlet pipe is connected to the first inlet pipe, and the other end of the second inlet pipe is connected to the first drain pipe; the first switching valve is disposed in the second inlet pipe; the second switching valve is disposed in the first inlet pipe, located between one end of the first condenser and one end of the second inlet pipe.

[0021] In this technical solution, the third heat exchange component also includes a second inlet pipe, a first switching valve, and a second switching valve. One end of the second inlet pipe is connected to the first inlet pipe, and the other end is connected to the first outlet pipe, thus enabling the installation of the second inlet pipe and allowing the first medium in the first inlet pipe to enter the first outlet pipe through the second inlet pipe. The first switching valve is located on the second inlet pipe, allowing it to control the opening and closing of the second inlet pipe. The second switching valve is located on the first inlet pipe, between one end of the first condenser and one end of the second inlet pipe, allowing it to control the opening and closing of the pipeline between the first inlet pipe and the first condenser. By setting the first and second switching valves, the flow of the first medium into the second inlet pipe or the first condenser can be controlled, thereby allowing different methods to be used to dissipate heat from the first medium flowing out of the first inlet pipe.

[0022] In some technical solutions of the present invention, optionally, the third heat exchange component includes a first sub-heat exchange component and a second sub-heat exchange component. The inlet of the first sub-heat exchange component is connected to the outlet of at least two second heat exchange components, and the outlet of the first sub-heat exchange component is connected to the inlet of at least two second heat exchange components. The inlet of the second sub-heat exchange component is connected to the outlet of the first heat exchange component, and the outlet of the second sub-heat exchange component is connected to the inlet of the first heat exchange component.

[0023] In this technical solution, the third heat exchange component includes a first sub-heat exchange component and a second sub-heat exchange component. The inlet of the first sub-heat exchange component is connected to the outlets of at least two second heat exchange components, and the outlet of the first sub-heat exchange component is connected to the inlet of at least two second heat exchange components. This allows the first sub-heat exchange component to condense the gaseous first medium flowing out of the at least two second heat exchange components and transport the condensed liquid first medium into the at least two second heat exchange components for heat exchange. Similarly, the inlet of the second sub-heat exchange component is connected to the outlet of the first heat exchange component, and the outlet of the second sub-heat exchange component is connected to the inlet of the first heat exchange component. This allows the second sub-heat exchange component to condense the gaseous first medium flowing out of the first heat exchange component and transport the condensed liquid first medium into the first heat exchange component for heat exchange. By setting up the first and second sub-heat exchange components, each heat exchange component is connected to an independent system for cooling, and each adjusts the evaporation temperature of the first medium to adapt to various operating conditions.

[0024] In some technical solutions of the present invention, optionally, the second heat exchange assembly further includes a third switching valve, a fourth switching valve, and a fifth switching valve. The third switching valve is located between one end of the first drain pipe and the inlet of one of the at least two second heat exchange assemblies; the fourth switching valve is located between one end of the first drain pipe and the inlet of the other of the at least two second heat exchange assemblies; and the fifth switching valve is located between one end of the first drain pipe and the inlet of the first heat exchange assembly.

[0025] In this technical solution, the second heat exchange assembly further includes a third, a fourth, and a fifth switching valve. The third switching valve is located between one end of the first drain pipe and the inlet of one of the at least two second heat exchange assemblies, allowing the third switching valve to regulate the flow rate of the first medium entering one of the at least two second heat exchange assemblies by controlling its opening. The fourth switching valve is located between one end of the first drain pipe and the inlet of another of the at least two second heat exchange assemblies, allowing the fourth switching valve to regulate the flow rate of the first medium entering the other of the at least two second heat exchange assemblies by controlling its opening. The fifth switching valve is located between one end of the first drain pipe and the inlet of the first heat exchange assembly, allowing the fifth switching valve to regulate the flow rate of the first medium entering the first heat exchange assembly by controlling its opening. This regulates the heat dissipation effect of the server.

Detailed Implementation

[0034] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0036] The following reference Figures 1 to 4 A cooling system 100 for an integrated heat pipe cooling cabinet according to some embodiments of the present invention is described.

[0037] like Figure 1 and Figure 2 As shown, the first aspect of the present invention provides a cooling system 100 for a heat pipe cooling integrated cabinet for a server 200. The cooling system 100 includes a first cabinet 102, a first heat exchange component 104, at least two second heat exchange components 114 and a third heat exchange component 120. The first cabinet 102 is used to install the server 200; the first heat exchange component 104 is disposed inside the first cabinet 102 and located on the first side of the first cabinet 102 in the height direction; at least two second heat exchange components 114 are disposed along the height direction of the first cabinet 102 and located on both sides of the first cabinet 102 in the length direction; the third heat exchange component 120 is located outside the first cabinet 102, the drain end of the third heat exchange component 120 is connected to one end of the first heat exchange component 104 and one end of the at least two second heat exchange components 114 respectively, and the inlet end of the third heat exchange component 120 is connected to the other end of the first heat exchange component 104 and the other end of the at least two second heat exchange components 114 respectively; wherein, the first medium can flow between the first heat exchange component 104, the at least two second heat exchange components 114 and the third heat exchange component 120.

[0038] In this technical solution, the cooling system 100 of the heat pipe cooling integrated cabinet is used for the server 200, thereby dissipating heat from the server 200. The cooling system 100 of the heat pipe cooling integrated cabinet includes a first cabinet 102, a first heat exchange component 104, at least two second heat exchange components 114, and a third heat exchange component 120. The first cabinet 102 is used to install the server 200. The first heat exchange component 104 is disposed inside the first cabinet 102, located on the first side of the first cabinet 102 in the height direction. That is, after the server 200 is installed inside the first cabinet 102, the first heat exchange component 104 is located on one side of the server 200, close to the server 200 for cooling, so that the first heat exchange component 104 can absorb the heat generated by the server 200 and avoid local hot spots within the first cabinet 102. At least two second heat exchange components 114 are arranged along the height direction of the first cabinet 102, located on both sides of the first cabinet 102 in the length direction. The at least two second heat exchange components 114 can be located on both sides of the server 200 along the length direction of the first cabinet 102, thereby absorbing the heat dissipated by the server 200 and further dissipating heat from the server 200. The third heat exchange component 120 is located outside the first cabinet 102. The drain end of the third heat exchange component 120 is connected to one end of the first heat exchange component 104 and one end of the at least two second heat exchange components 114, respectively. The inlet end of the third heat exchange component 120 is connected to the other end of the first heat exchange component 104 and the other end of the at least two second heat exchange components 114, respectively, so as to realize the communication between the first heat exchange component 104, the at least two second heat exchange components 114 and the third heat exchange component 120. The first medium can flow between the first heat exchange component 104, at least two second heat exchange components 114 and the third heat exchange component 120, so that the first medium can absorb the heat generated by the server 200 in the first heat exchange component 104 and at least two second heat exchange components 114. After absorbing heat and evaporating, it can flow into the third heat exchange component 120 and condense into a low-temperature liquid form. After condensing in the third heat exchange component 120, the first medium can flow back into the first heat exchange component 104 and at least two second heat exchange components 114 to continue evaporating and absorbing heat. The first medium can perform circulating heat exchange on the server 200 through circulating flow. By setting a first heat exchange component 104, at least two second heat exchange components 114, and a third heat exchange component 120 on the first cabinet 102, the server 200 can be directly cooled, avoiding the generation of local hot spots. Compared with using air conditioning equipment to cool the server 200 with high power consumption, not only can the generation of local hot spots be avoided, but also energy waste can be avoided since there is no need to use air conditioning equipment to cool the server 200 with high power consumption, thereby improving the heat dissipation efficiency of the server 200.

[0039] Specifically, the data center is a computer room, the first cabinet 102 is located inside the computer room, the third heat exchange component 120 is located outside the computer room, inside the second cabinet 156, and the second cabinet 156 is located outside the computer room.

[0040] Specifically, the first medium and the second medium are refrigerants, which can be Freon.

[0041] Specifically, after the first medium condenses in the third heat exchange component 120, it can flow back to the first heat exchange component 104 and the second heat exchange component 114 under the action of gravity to cool the server 200.

[0042] Specifically, in Figure 1 In the diagram, arrow A represents the height direction of the first cabinet 102, which is the direction from the bottom wall to the top wall of the first cabinet 102. Arrow B represents the length direction of the first cabinet 102, which is the direction from one opening side of the first cabinet 102 to the other side.

[0043] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0044] like Figure 1 and Figure 2 As shown, at least two second heat exchange assemblies 114 include a first sub-heat exchanger 116 and a second sub-heat exchanger 118.

[0045] In this technical solution, at least two second heat exchange components 114 include a first sub-heat exchanger 116 and a second sub-heat exchanger 118. The first sub-heat exchanger 116 is located on a first side of the first cabinet 102 along its length and is connected to the first cabinet 102 to enable installation of the first cabinet 102 and improve the stability of the first cabinet 102 after installation. The second sub-heat exchanger 118 is located on a second side of the first cabinet 102 along its length and is connected to the first cabinet 102 to enable installation of the first cabinet 102 and improve the stability of the second cabinet 156 after installation. By setting the first sub-heat exchanger 116 and the second sub-heat exchanger 118, heat dissipated from the server 200 to the outside of the first cabinet 102 can be cooled.

[0046] Specifically, the number of the first sub-heat exchanger 116 and the second sub-heat exchanger 118 can be adjusted according to the heat exchange area of ​​the rack load. Multiple servers 200 can be installed inside the first rack 102. These servers 200 generate significant heat during operation. Therefore, based on the number of servers 200, the heat exchange area at the locations of the first sub-heat exchanger 116 and the second sub-heat exchanger 118 can be determined, thereby selecting the appropriate number of first sub-heat exchangers 116 and the second sub-heat exchanger 118, or adjusting the area of ​​the first sub-heat exchanger 116 and the second sub-heat exchanger 118.

[0047] Specifically, there are multiple first sub-heat exchangers 116 and multiple second sub-heat exchangers 118.

[0048] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0049] like Figure 1 and Figure 2 As shown, the first heat exchange component 104 includes a first heat exchange tube 106, which is located on one side of the server 200 along the length of the first cabinet 102.

[0050] In this technical solution, the first heat exchange component 104 includes a first heat exchange pipe 106, which is located on one side of the server 200 along the length of the first cabinet 102, so as to realize the installation of the first heat exchange pipe 106, and then cool the server 200 through the heat exchange pipe, thereby increasing the heat dissipation area and improving the heat exchange efficiency.

[0051] Specifically, a first distribution pipe 108 is provided at one end of the first heat exchange tube 106, and the first distribution pipe 108 is connected to the drain end of the third heat exchange component 120, so that the first medium can flow into the first heat exchange tube 106. A first collecting pipe 110 is provided at the other end of the first heat exchange tube 106, and the first collecting pipe 110 is connected to the inlet end of the third heat exchange component 120, so that the first medium can flow back into the third heat exchange component 120 for condensation after heat exchange in the first heat exchange tube 106.

[0052] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0053] like Figure 1 and Figure 2 As shown, the installation direction of the first heat exchange tube 106 is the same as the installation direction of the server 200.

[0054] In this technical solution, the installation direction of the first heat exchanger pipe 106 is the same as the installation direction of the server 200, so that the server 200 and the first heat exchanger pipe 106 are arranged in parallel after installation. This facilitates the installation of the server 200 and the first heat exchanger pipe 106 and avoids interference between them during installation. The parallel arrangement also ensures that the first heat exchanger pipe 106 dissipates heat evenly to the server 200 at all locations.

[0055] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0056] like Figure 1 and Figure 2 As shown, the third heat exchange assembly 120 includes a first inlet pipe 122, a first outlet pipe 124, and a first condenser 126. One end of the first inlet pipe 122 is connected to the outlet of the first heat exchange assembly 104 and the outlets of at least two second heat exchange assemblies 114; one end of the first outlet pipe 124 is connected to the inlet of the first heat exchange assembly 104 and the inlet of at least two second heat exchange assemblies 114; one end of the first condenser 126 is connected to the other end of the first inlet pipe 122, and the other end of the first condenser 126 is connected to the other end of the first outlet pipe 124.

[0057] In this technical solution, the third heat exchange assembly 120 includes a first inlet pipe 122, a first outlet pipe 124, and a first condenser 126. One end of the first inlet pipe 122 is connected to the outlet of the first heat exchange assembly 104 and the outlets of at least two second heat exchange assemblies 114, thereby connecting the first inlet pipe 122 with the first heat exchange assembly 104 and the second heat exchange assemblies 114. One end of the first outlet pipe 124 is connected to the inlet of the first heat exchange assembly 104 and the inlets of at least two second heat exchange assemblies 114, thereby connecting the first outlet pipe 124 with the first heat exchange assembly 104 and the second heat exchange assemblies 114. One end of the first condenser 126 is connected to the other end of the first liquid inlet pipe 122, and the other end of the first condenser 126 is connected to the other end of the first liquid outlet pipe 124. The first liquid inlet pipe 122 and the first liquid outlet pipe 124 are connected through the first condenser 126, so that the first condenser 126 can condense the high-temperature gaseous first medium after heat exchange in the first heat exchange component 104 and at least two second heat exchange components 114. After the first medium is condensed in the first condenser 126, it can flow back to the first heat exchange component 104 and at least two second heat exchange components 114 under the action of gravity to continue heat exchange, so as to realize the circulating heat dissipation of the server 200, thereby improving the heat dissipation efficiency.

[0058] Specifically, when the temperature outside the computer room is low, the first condenser 126 can be used to cool the first medium outdoors, thereby removing the heat generated by the server 200.

[0059] Specifically, the third heat exchange component 120 also includes a first drive pump 112, which is located in the second drain pipe. The first drive pump 112 can be a refrigerant pump, which provides circulation power in scenarios where the refrigerant gravity return slope is not met.

[0060] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0061] like Figure 1 and Figure 2 As shown, the third heat exchange assembly 120 also includes a first heat exchanger 128, which is arranged in parallel with the first drain pipe 124 and is capable of exchanging heat with the first medium in the first drain pipe 124.

[0062] In this technical solution, by setting the first heat exchanger 128 and the first drain pipe 124 side by side, the first heat exchanger 128 is located on one side of the first drain pipe 124, allowing the first heat exchanger 128 to exchange heat with the first medium inside the first drain pipe 124. This allows the first heat exchanger 128 to lower the temperature of the first medium inside the first drain pipe 124, ensuring that the first medium inside the first drain pipe 124 is completely cooled before entering the second pipeline and the second heat exchange assembly 114 to dissipate heat from the server 200, thus ensuring the stability of heat dissipation for the server 200. By using the first heat exchanger 128 to supplement the cooling of the first medium inside the first drain pipe 124, the first medium inside the first drain pipe 124 can be completely cooled even when the outside temperature of the computer room is high.

[0063] When the outdoor temperature is relatively high, i.e., T1≤outdoor temperature<T2, since the first condenser 126 cannot completely condense the first medium, the first heat exchanger 128 can be operated to exchange heat with the first medium in the first drain pipe 124, thereby achieving supplemental cooling of the first medium and ensuring the heat dissipation effect of the server 200.

[0064] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0065] like Figure 1 and Figure 2As shown, the first heat exchanger 128 includes a second condenser 130, a compressor 132, an expansion valve 134, and a first evaporator 136. One end of the compressor 132 is connected to one end of the second condenser 130; one end of the expansion valve 134 is connected to the other end of the second condenser 130; the first evaporator 136 is located near the first drain pipe 124, one end of the first evaporator 136 is connected to one end of the expansion valve 134, and the other end of the first evaporator 136 is connected to the other end of the compressor 132; the second medium can flow between the compressor 132, the second condenser 130, the expansion valve 134, and the first evaporator 136.

[0066] In this technical solution, the third heat exchanger includes a second condenser 130, a compressor 132, an expansion valve 134, and a first evaporator 136. One end of the compressor 132 is connected to one end of the second condenser 130; one end of the expansion valve 134 is connected to the other end of the second condenser 130; one end of the first evaporator 136 is connected to one end of the expansion valve 134, and the other end of the first evaporator 136 is connected to the other end of the compressor 132, thereby achieving the connection between the compressor 132, the second condenser 130, the expansion valve 134, and the first evaporator 136, and allowing the second medium to flow between the compressor 132, the second condenser 130, the expansion valve 134, and the first evaporator 136. The low-pressure second medium is compressed into a high-temperature, high-pressure gas by the compressor 132 and then condensed into a high-pressure liquid at the second condenser 130. After being throttled into a low-pressure liquid by the expansion valve 134, it evaporates and absorbs heat in the first evaporator 136. Since the first evaporator 136 is located close to the first drain pipe 124, the second medium can cool the first medium in the first drain pipe 124 during the evaporation and heat absorption process in the first evaporator 136. This allows for the circulation and replenishment of cooling for the first medium, thereby ensuring the stability of heat dissipation for the server 200.

[0067] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0068] like Figure 1 and Figure 2 As shown, the third heat exchange assembly 120 also includes a second inlet pipe 138, a first switching valve 140, and a second switching valve 142. One end of the second inlet pipe 138 is connected to the first inlet pipe 122, and the other end of the second inlet pipe 138 is connected to the first drain pipe 124; the first switching valve 140 is disposed in the second inlet pipe 138; the second switching valve 142 is disposed in the first inlet pipe 122, located between one end of the first condenser 126 and one end of the second inlet pipe 138.

[0069] In this technical solution, the third heat exchange assembly 120 further includes a second inlet pipe 138, a first switching valve 140, and a second switching valve 142. One end of the second inlet pipe 138 is connected to the first inlet pipe 122, and the other end of the second inlet pipe 138 is connected to the first drain pipe 124, thereby enabling the installation of the second inlet pipe 138 so that the first medium in the first inlet pipe 122 can enter the first drain pipe 124 through the second inlet pipe 138. The first switching valve 140 is disposed on the second inlet pipe 138 so that it can control the opening and closing of the second inlet pipe 138. The second switching valve 142 is disposed on the first inlet pipe 122, located between one end of the first condenser 126 and one end of the second inlet pipe 138, so that it can control the opening and closing of the pipeline between the first inlet pipe 122 and the first condenser 126. By setting the first switching valve 140 and the second switching valve 142, the flow of the first medium into the second inlet pipe 138 or the first condenser 126 can be controlled, thereby allowing the first medium flowing out of the first inlet pipe 122 to be cooled in different ways.

[0070] When the temperature outside the computer room is very high, i.e., when the outdoor temperature T≥T2, the first condenser 126 cannot provide cooling capacity. The liquid inlet of the first condenser 126 can be closed, allowing the first medium to enter the first drain pipe 124 through the second liquid inlet pipe 138. Only the third heat exchanger is used to cool the first medium, and then the heat in the computer room is removed through the third heat exchanger.

[0071] Specifically, the first switching valve 140 is a first electric valve, and the second switching valve 142 is a second electric valve. The use of electric valves facilitates the control of the pipeline's on / off state.

[0072] Specifically, the first heat exchange tube 106 is a plate heat exchanger. The first heat exchange component 104, at least two second heat exchange components 114 and the first cabinet 102 form an integrated cabinet on the indoor side of the computer room. At least two second heat exchange components 114 are arranged in parallel on the top of each server 200, without affecting the installation and disassembly of the server 200. The first medium enters each distributed plate heat exchanger through the first drain pipe 124, absorbs heat and vaporizes close to the server 200, and then goes to the outside for cooling through the first inlet pipe 122.

[0073] The following three cooling modes are included in the process of cooling the server 200:

[0074] In pure heat pipe mode, the first condenser 126 is a heat pipe condenser. When the temperature outside the computer room is low, i.e., when the outdoor temperature T < T1, the first switch valve 140 is closed and the second switch valve 142 is opened. At this time, the outdoor temperature is relatively low, and the heat in the computer room is completely removed through the cooling cycle of the first condenser 126. There is no need to start the third heat exchanger to make up for the cooling cycle. The overall energy consumption unit is small and the system has extremely high energy efficiency. T1 can be adjusted according to specific needs.

[0075] In the mechanical compression cooling mode, i.e., the first heat exchanger 128 provides cooling for the first medium, when the outdoor temperature is relatively high (i.e., T1 ≤ outdoor temperature T < T2), the first switch valve 140 is closed and the second switch valve 142 is opened. At this time, the outdoor temperature is relatively high, and the heat in the machine room is pre-cooled by the first condenser 126. The first heat exchanger 128 then circulates to provide cooling. Since the compressor 132, which has the highest energy consumption, does not need to run at full load at this time, the heat dissipation system still has good energy efficiency. T1 and T2 are temperature thresholds that can be adjusted according to specific needs.

[0076] The mechanical compression full-cooling supplement mode utilizes only the first heat exchanger 128 for cooling. When the outside temperature is high (T ≥ T2), the first switching valve 140 opens and the second switching valve 142 closes. At this point, the high outdoor temperature means the first condenser 126 can no longer provide cooling, and the heat inside the computer room needs to be completely removed by the first heat exchanger 128's cooling supplement cycle. Because the system cools close to the heat load, the refrigerant evaporation temperature inside the computer room is significantly higher than in a typical air-cooled system, thus increasing T2 accordingly. This greatly reduces the operating time of this mode, resulting in a limited increase in overall energy consumption. T2 can be adjusted according to specific needs.

[0077] Specifically, a first evaporation spray module is provided on one side of the first condenser 126, so that the first evaporation spray module can spray coolant onto the first condenser 126, thereby shortening the cooling time of the first medium and improving the condensation efficiency.

[0078] Specifically, a second evaporation spray module is provided on one side of the second condenser 130, which can spray coolant onto the second condenser 130, thereby shortening the cooling time of the first medium and improving the condensation efficiency.

[0079] Specifically, the first condenser 126 and the second condenser 130 are arranged in a "V" shape, so that the first condenser 126 and the second condenser 130 can share a fan for cooling. The first evaporation spray module and the second evaporation spray module are the same evaporation spray module, which can reduce costs and reduce the space occupied.

[0080] The heat pipe compression refrigeration unit consists of a heat pipe refrigeration cycle and a mechanical compression supplementary cooling cycle. The heat pipe refrigeration cycle mainly includes the first condenser 126 and corresponding piping. When the outdoor temperature is low, the high-temperature gaseous refrigerant evaporated from the indoor unit is condensed into a low-temperature liquid by the heat pipe condenser and then flows back to the indoor cabinet side by gravity. The mechanical compression refrigeration cycle mainly includes the compressor 132, the second condenser 130, the expansion valve 134, the first evaporator 136, and corresponding piping. When the outdoor temperature is high, the low-pressure refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 132 and then condensed into a high-pressure liquid at the second condenser 130. After being throttled into a low-pressure liquid by the expansion valve 134, it evaporates and absorbs heat in the first evaporator 136, providing supplementary cooling for the first medium circulation in the first drain pipe 124.

[0081] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0082] like Figure 3 and Figure 4 As shown, the third heat exchange assembly 120 includes a first sub-heat exchange assembly 150 and a second sub-heat exchange assembly 152. The inlet of the first sub-heat exchange assembly 150 is connected to the outlet of at least two second heat exchange assemblies 114, and the outlet of the first sub-heat exchange assembly 150 is connected to the inlet of at least two second heat exchange assemblies 114. The inlet of the second sub-heat exchange assembly 152 is connected to the outlet of the first heat exchange assembly 104, and the outlet of the second sub-heat exchange assembly 152 is connected to the inlet of the first heat exchange assembly 104.

[0083] In this technical solution, the third heat exchange component 120 includes a first sub-heat exchange component 150 and a second sub-heat exchange component 152. The inlet of the first sub-heat exchange component 150 is connected to the outlet of at least two second heat exchange components 114, and the outlet of the first sub-heat exchange component 150 is connected to the inlet of at least two second heat exchange components 114, so as to realize the installation of the first sub-heat exchange component 150, so that the first sub-heat exchange component 150 can condense the gaseous first medium flowing out of at least two second heat exchange components 114, and transport the condensed liquid first medium into at least two second heat exchange components 114 for heat exchange. The inlet of the second sub-heat exchanger 152 is connected to the outlet of the first heat exchanger 104, and the outlet of the second sub-heat exchanger 152 is connected to the inlet of the first heat exchanger 104. This allows the installation of the second sub-heat exchanger 152, which can condense the gaseous first medium flowing out of the first heat exchanger 104 and transport the condensed liquid first medium into the first heat exchanger 104 for heat exchange. By setting up the first sub-heat exchanger 150 and the second sub-heat exchanger 152, the first heat exchanger 104 and the second heat exchanger 114 are respectively connected to independent systems for cooling, and each adjusts the evaporation temperature of the first medium to adapt to various operating conditions.

[0084] Specifically, the second sub-heat exchanger 118 is a pure heat pipe main unit system, and the first sub-heat exchanger 116 is a heat pipe compression refrigeration integrated system. For scenarios where the first cabinet 102 has been installed in the computer room, the first heat exchange component 104 and at least two second heat exchange components 114 can be connected to different main unit systems for heat dissipation. The first heat exchange component 104, which is close to the server 200 and has a high evaporation temperature, is connected to the pure heat pipe main unit system, i.e., a system that only uses the evaporator to dissipate heat from the refrigerant. At least two second heat exchange components 114 are connected to the heat pipe compression refrigeration integrated system, which consists of a heat pipe refrigeration cycle and a mechanical compression cooling cycle. Compared to the heat pipe compression refrigeration integrated system, the pure heat pipe main unit eliminates the mechanical compression cooling cycle and mainly consists of a heat pipe condenser, providing natural cooling throughout the year with extremely high efficiency. A refrigerant pump can be selected for scenarios where the refrigerant gravity return slope is not met.

[0085] Specifically, there are multiple first sub-heat exchangers 116 and multiple second sub-heat exchangers 118, multiple first cabinets 102, multiple servers 200, multiple first heat exchange components 104, and multiple at least two second heat exchange components 114 installed in multiple first cabinets 102. The multiple first sub-heat exchangers 116 and multiple second sub-heat exchangers 118 are connected to the multiple first heat exchange components 104 and multiple at least two second heat exchange components 114, thereby realizing heat dissipation for the multiple servers 200 in the multiple first cabinets 102.

[0086] Specifically, the second sub-heat exchanger 118 includes a third condenser 158. The two ends of the third condenser 158 are connected to the two ends of the first heat exchange component 104 through which the first medium flows, so that the first medium in the first heat exchange component 104 can flow into the third condenser 158 for heat exchange. A second drive pump 154 ​​is provided on the pipeline between the third condenser 158 and the second pipeline. The second drive pump 154 ​​is a fluorine pump. The second drive pump 154 ​​can drive the flow of the first medium, thereby improving the heat dissipation efficiency.

[0087] Specifically, in Figure 4 In the image, the arrow indicates the direction of the first medium circulation within the second sub-heat exchanger 118.

[0088] This embodiment provides a cooling system 100 for an integrated heat pipe cooling cabinet. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0089] like Figure 1 and Figure 2 As shown, the second heat exchange assembly 114 further includes a third switching valve 144, a fourth switching valve 146, and a fifth switching valve 148. The third switching valve 144 is located between one end of the first drain pipe 124 and the inlet of one of the at least two second heat exchange assemblies 114; the fourth switching valve 146 is located between one end of the first drain pipe 124 and the inlet of the other of the at least two second heat exchange assemblies 114; and the fifth switching valve 148 is located between one end of the first drain pipe 124 and the inlet of the first heat exchange assembly 104.

[0090] In this technical solution, the second heat exchange assembly 114 further includes a third switching valve 144, a fourth switching valve 146, and a fifth switching valve 148. The third switching valve 144 is located between one end of the first drain pipe 124 and the inlet of one of the at least two second heat exchange assemblies 114, allowing the installation of the third switching valve 144. This enables the third switching valve 144 to regulate the flow rate of the first medium entering one of the at least two second heat exchange assemblies 114 by controlling the opening degree of the control valve. The fourth switching valve 146 is located between one end of the first drain pipe 124 and the inlet of the other of the at least two second heat exchange assemblies 114, allowing the fourth switching valve 146 to regulate the flow rate of the first medium entering the other of the at least two second heat exchange assemblies 114 by controlling the opening degree of the control valve. The fifth switching valve 148 is located between one end of the first drain pipe 124 and the inlet of the first heat exchange component 104. This allows the fifth switching valve 148 to regulate the flow rate of the first medium entering the first heat exchange component 104 through the first drain pipe 124 by controlling its opening. This, in turn, regulates the heat dissipation effect of the server 200.
