Detailed ways

In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings.

With the development of computer and network technology, the functions embodied in the cabinet are becoming more and more powerful. The cabinet can be used in network wiring room, central computer room, data computer room, control center, monitoring center, etc. to accommodate electronic equipment, so as to realize dustproof and waterproof protection for electronic equipment and ensure the normal operation of electronic equipment. With the continuous increase of the power of high-performance electronic equipment, the integration of the cabinet is getting higher and higher, and thus the power density of the cabinet is getting higher and higher. Because electronic equipment generates heat when it is working, high-power cabinets will cause excessive heat load on the cabinet, and continuous high temperature will seriously affect the performance of electronic equipment, and even cause damage to electronic equipment. Therefore, in order to ensure the reliable operation of electronic equipment, the cabinet often needs to have a good heat dissipation capability. At present, the heat dissipation of the cabinet is mainly realized by configuring the heat dissipation system.

Referring to FIG. 1 , FIG. 1 is a schematic structural diagram of a heat dissipation system provided by an embodiment of the present application. The cooling system 1 generally includes a cooling module 100 , a cooled module 200 and a connecting pipeline 300 , and the cooling module 100 and the cooled module 200 are connected through the connecting pipeline 300 to form a closed circulation loop. A working medium is set in the connecting pipeline 300. When the heat dissipation system 1 is working, the working medium can exchange heat with the outside to cool down in the cooling module 100, and then flow through the connecting pipeline 300 to the cooled module 200. 200 exchanges heat with the electronic equipment and absorbs the heat generated during the working process of the electronic equipment, thereby cooling the electronic equipment. After the heat exchange heats up, the working fluid returns to the cooling module 100 through the connecting pipeline 300 to complete a cycle.

In the embodiment of the present application, the cooling module 100 can be a liquid-assisted air cooling unit (liquid-assisted air cooling, LAAC) that adopts air cooling and heat dissipation, or can also be a cooling distribution unit (coolant distribution unit) that adopts liquid cooling and heat dissipation. units, CDU), this application does not make specific restrictions on this, and the two cooling modules are introduced separately below.

Referring to FIG. 2 , FIG. 2 is a schematic structural diagram of a liquid-cooled auxiliary air-cooled unit. The liquid-cooled auxiliary air-cooling unit may include a circulation pump 110, an air-cooled heat exchanger 120, and a fan 130. The circulation pump 110, the air-cooled heat exchanger 120, and the cooled module 200 are connected in sequence through connecting pipelines. One side of the cold heat exchanger 120 . The circulating pump 110 can drive the working medium to flow in the circulation loop. After the cooled module 200 exchanges heat with the electronic equipment and heats up, the working medium enters the inner channel of the air-cooled heat exchanger 120; at the same time, the fan 130 rotates to drive the air flow. The air around the cold heat exchanger 120 flows, and the cold air outside the air-cooled heat exchanger 120 exchanges heat with the high-temperature working medium in the internal flow channel and takes away the heat, thereby cooling the working medium, and the cooled working medium circulates Driven by the pump 110 , it enters the cooled module 200 again, so as to reciprocate and realize continuous heat dissipation of the electronic equipment.

Referring to FIG. 3 , FIG. 3 is a schematic structural diagram of the cooling distribution unit. The cold distribution unit may include a circulation pump 110 and a liquid-cooled heat exchanger 140 , and the circulation pump 110 , the liquid-cooled heat exchanger 140 and the cooled module 200 are connected in sequence through connecting pipelines. The liquid-cooled heat exchanger 140 can be a double-channel heat exchanger, including an isolated working medium flow channel 141 and a chilled water flow channel 142. The working medium flow channel 141 and the chilled water flow channel 142 can perform heat exchange. Specifically, the cooling module 200 may be connected to the working medium channel 141 , and the chilled water channel 142 may communicate with an external chilled water supply pipeline. The circulating pump 110 can drive the working fluid to flow in the circulation loop. The working fluid enters the liquid cooling heat exchanger 140 after heat exchange between the cooled module 200 and the electronic equipment to heat up, and exchanges heat with the chilled water in the chilled water channel 142. After that, The cooled working medium enters the cooled module 200 again under the drive of the circulating pump 110 , so as to reciprocate and realize the continuous heat dissipation of the electronic equipment.

Please refer to FIG. 1 again. In the embodiment of the present application, the cooled module 200 may include a cold plate 211 , and the cold plate 211 is in thermal contact with an electronic device that needs to dissipate heat. It is worth mentioning that the heat conduction contact can be understood as heat exchange between the cold plate 211 and the electronic device through direct contact or indirect contact. The cold plate 211 is provided with flow passages, and the two ends of the flow passages of the cold plate 211 communicate with the cooling module 100 respectively. The other end of the flow channel of the plate 211 flows out of the cold plate 211 and returns to the cooling module 100 for cooling.

It should be understood that there are usually several subracks installed in the cabinet. In order to dissipate heat for the electronic equipment or modules carried by each subrack, for each subrack that needs heat dissipation, the cooled modules 200 can be separately The cooled units 210 corresponding thereto are provided. At this time, the heat dissipation system 1 can also include a first liquid distributor 400, which is connected between the cooling module 100 and the cooled module 200, and can be used for The cryogenic working fluid output from the cooling module 100 can be distributed to the cooled unit 210 corresponding to each subrack.

During specific implementation, the first liquid separator 400 may be provided with an isolated first flow channel and a second flow channel, wherein the first flow channel may include a liquid inlet 411 and a plurality of liquid outlets 412, the first flow channel The liquid inlet 411 communicates with the circulation pump 110 of the cooling module 100, and each liquid outlet 412 of the first flow channel is connected with the liquid inlet of each cooled unit 210 respectively; the second flow channel may include a plurality of liquid inlets 421 and One liquid outlet 422, each liquid inlet 421 of the second flow path is connected with the liquid outlet of each cooled unit 210 respectively, the liquid outlet 422 of the second flow path is connected with the heat exchanger (air-cooled) of the cooling module 100 heat exchanger 120 or liquid-cooled heat exchanger) communicates. Wherein, the number of liquid outlets 412 of the first flow channel and the number of liquid inlets 421 of the second flow channel may not be less than the number of cooled units 210, so as to ensure the cooling effect of each subframe inside the cabinet. When connecting with the cooled unit 210, the extra liquid outlet 412 of the first flow channel and the extra liquid inlet 421 of the second flow channel can be closed by valves, or can be blocked by some sealing structures to avoid the first The working medium in a liquid separator 400 leaks.

When the heat dissipation system 1 is working, the circulation pump 110 drives the low-temperature working medium to enter the first liquid distributor 400 through the liquid inlet 411 of the first flow channel, and then distributes it to each cooled unit 210 through each liquid outlet 412 of the first flow channel. After the cooled unit 210 exchanges heat with the electronic equipment in the corresponding subframe, it returns to the first liquid distributor 400 through the liquid inlets 421 of the second flow channel, and then returns to the first liquid distributor 400 through the liquid outlet 422 of the second flow channel. Enter the heat exchanger of the cooling module 100 for cooling. It can be seen that the working fluid flowing in the first flow channel is a low temperature working fluid, and the working fluid flowing in the second flow channel is a high temperature working fluid. In order to reduce the heat conduction between the high temperature working fluid in the second flow channel and the low temperature working fluid in the first flow channel , The first flow channel and the second flow channel can be heat-insulated, for example, a heat insulating material can be arranged between the two, or the outer peripheries of the first flow channel and the second flow channel can be respectively provided with thermal insulation materials. It can be understood that when the first flow channel and the second flow channel are respectively cavities opened inside the first liquid distributor 400 , the first liquid distributor 400 can be made of materials with relatively poor thermal conductivity.

In addition, in some cases, in order to improve the integration of the cabinet, multiple electronic devices can also be arranged on the subrack. There are two cold plates 211, and these cold plates 211 can be in thermal contact with each electronic device in one-to-one correspondence. At this time, the cooled unit 210 may further include a second liquid distributor 212, and the second liquid distributor 212 may be used to redistribute the working fluid in the cooled unit 210 from the first liquid distributor 400, so that the working fluid It can enter into each cold plate 211 to dissipate heat for corresponding electronic equipment.

Similar to the first liquid distributor 400, the second liquid distributor 212 may also include two isolated flow channels, namely a third flow channel and a fourth flow channel, wherein the third flow channel may include a liquid inlet 2121 and a plurality of liquid outlets 2122, the liquid inlet 2121 of the third channel communicates with one of the liquid outlets 412 of the first channel of the first liquid separator 400, and each liquid outlet 2122 of the third channel communicates with each One end of the flow channel of the cold plate 211 is respectively connected; the fourth flow channel may include a plurality of liquid inlets 2123 and one liquid outlet 2124, and each liquid inlet 2123 of the fourth flow channel is connected to the other end of each cold plate 211 flow channel respectively. Connected, the liquid outlet 2124 of the fourth channel communicates with one of the liquid inlets 421 of the second channel of the first liquid separator 400 . It can be understood that the liquid inlet of the cooled unit 210 is the liquid inlet 2121 of the third flow channel, and the liquid outlet of the cooled unit is the liquid outlet 2124 of the fourth flow channel. Wherein, the number of liquid outlets 2122 of the third channel and the number of liquid inlets 2123 of the fourth channel may not be less than the number of internal cold plates 211 of the cooled unit 210, so as to ensure the heat dissipation effect of each electronic device . When connecting with the cold plate 211, the extra liquid outlet 2122 of the third flow channel and the extra liquid inlet 2123 of the fourth flow channel can be closed by valves, or can be blocked by some sealing structural parts, so as to avoid the The working fluid in the secondary liquid separator 212 leaks.

The working medium in the first flow channel of the first liquid distributor 400 is distributed to the second liquid distributor 212 of each cooled unit 210 through its respective liquid outlets 412, and then distributed to each of the liquid outlets 2123 of the third flow channel. The cold plate 211 returns to the second liquid distributor 212 through each liquid inlet 2123 of the fourth flow channel after the heat exchange between the cold plate 211 and the corresponding electronic equipment, and then returns to the second liquid distributor 212 through the liquid outlet 2124 of the fourth flow channel. To the second flow channel of the first dispenser 400. Similarly, since the working fluid flowing in the third flow channel is low temperature working fluid, the working fluid flowing in the fourth flow channel is high temperature working fluid, in order to reduce the high temperature working fluid in the fourth flow channel and the low temperature working fluid in the third flow channel For heat conduction, the third flow channel and the fourth flow channel can be heat-insulated, and the specific setting method can refer to the above description of the first liquid distributor 400, which will not be repeated here.

It should be noted that during the installation, use and maintenance of the heat dissipation system 1, it includes the installation of the initial working fluid injection, the plugging and unplugging of various connection joints in the mid-term use, the aging and damage of the later circulation loop, and the maintenance process. In scenarios such as refilling of the working fluid, the existing working fluid in the heat dissipation system 1 will leak slowly due to tiny gaps caused by incomplete process sealing, and will also evaporate due to the long-term operation of the heat dissipation system 1 . When the working medium in the heat dissipation system 1 is not replenished in time, the heat dissipation performance of the entire heat dissipation system 1 will be significantly reduced. In addition, the lack of working fluid will also cause the circulation pump of the cooling module 100 to run idly, which will not only reduce the efficiency of the circulation pump 110, but also generate relatively large noise, which will affect the service life of the circulation pump 110. Therefore, in order to maintain the heat dissipation performance of the heat dissipation system 1 and the normal operation of the circulation pump 110 , it is a realistic requirement to replenish the working medium in the heat dissipation system 1 in time.

Based on this, in the embodiment of the present application, the heat dissipation system may also include a liquid replenishment device for replenishing the working medium, and the liquid replenishment device can make up for the shortage of the working medium caused by the evaporation and leakage of the working medium, thereby improving the heat dissipation of the heat dissipation system Performance, to achieve good heat dissipation of electronic equipment, to ensure the normal operation of electronic equipment.
