With the development of computer and network technologies, the functions embodied by the cabinet become more and more powerful. The cabinet can be used in places such as network wiring, data centers, monitoring centers and the like, and is used for accommodating and protecting electronic equipment and ensuring the normal operation of the electronic equipment.

When the working medium in the circulation loop can not be supplemented in time, the heat dissipation performance of the whole heat dissipation system is obviously reduced. Therefore, in order to maintain the heat dissipation performance of the heat dissipation system and ensure the normal operation of the electronic equipment, the working medium in the heat dissipation system is supplemented in time, which is a practical requirement.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

With the development of computer and network technologies, the functions embodied by the cabinet become more and more powerful. The cabinet can be used among network wiring lines, a central machine room, a data machine room, a control center, a monitoring center and the like, and is used for accommodating electronic equipment, so that the electronic equipment is protected from dust and water, and the normal operation of the electronic equipment is ensured. With the continuous increase of power of high-performance electronic equipment, the integration level of the cabinet is higher and higher, and therefore, the power density of the cabinet is higher and higher. Because the electronic equipment can generate heat during operation, the high-power cabinet can cause overlarge heat load of the cabinet, and the performance of the electronic equipment can be seriously influenced by continuous high temperature, even the electronic equipment is damaged. Therefore, in order to ensure reliable operation of the electronic device, the cabinet often needs to have good heat dissipation capability. At present, heat dissipation of a cabinet is mainly realized by configuring a heat dissipation system.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a heat dissipation system according to an embodiment of the present disclosure. The heat dissipation system 1 may generally include a cooling module 100, a cooled module 200, and a connecting pipe 300, wherein the cooling module 100 and the cooled module 200 are connected by the connecting pipe 300 to form a closed circulation loop. Set up the working medium in connecting line 300, cooling system 1 is at the during operation, and the working medium can be in cooling module 100 with external heat transfer cooling, then flow to by cooling module 200 through connecting line 300, is being cooled off module 200 and electronic equipment heat transfer, absorbs the heat that produces in the electronic equipment course of operation to for the electronic equipment cooling, the working medium is after the heat transfer intensifies and is returned to cooling module 100 through connecting line 300 once more, accomplishes a circulation.

In this embodiment of the application, the cooling module 100 may be a liquid-cooled auxiliary air cooling unit (LAAC) using air-cooled heat dissipation, or may also be a Cold Distribution Unit (CDU) using liquid-cooled heat dissipation, and this application does not specifically limit this, and these two cooling modules are introduced below respectively.

Referring to fig. 2, fig. 2 is a schematic structural view of the liquid-cooling auxiliary air-cooling unit. The liquid cooling 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 sequentially communicated through a connection pipeline, and the fan 130 is disposed on one side of the air-cooled heat exchanger 120. The circulating pump 110 can drive the working medium to flow in the circulating loop, and the working medium enters the internal flow channel of the air-cooled heat exchanger 120 after being subjected to heat exchange and temperature rise between the cooling module 200 and the electronic equipment; meanwhile, the fan 130 rotates to drive the air around the air-cooled heat exchanger 120 to flow, the cold air outside the air-cooled heat exchanger 120 exchanges heat with the high-temperature working medium in the internal flow channel of the air-cooled heat exchanger and takes away heat, so that the working medium is cooled, and the cooled working medium enters the cooled module 200 again under the driving of the circulating pump 110, so that the electronic equipment is continuously cooled through the reciprocating circulation.

Referring to fig. 3, fig. 3 is a schematic view of the structure of the refrigeration capacity distribution unit. The cold energy distribution unit may include a circulation pump 110 and a liquid cooling heat exchanger 140, and the circulation pump 110, the liquid cooling heat exchanger 140 and the module to be cooled 200 are sequentially communicated through a connection pipeline. The liquid cooling heat exchanger 140 may be a double-flow heat exchanger, and includes a working medium flow channel 141 and a chilled water flow channel 142, which are isolated from each other, the working medium flow channel 141 and the chilled water flow channel 142 may perform heat exchange, the working medium flow channel 141 may be specifically connected to the circulation pump 110 and the cooled module 200, and the chilled water flow channel 142 may be communicated with an external chilled water supply pipeline. The circulating pump 110 can drive the working medium to flow in the circulating loop, the working medium enters the liquid-cooling heat exchanger 140 after being heated by the heat exchange between the cooling module 200 and the electronic device, and exchanges heat with the chilled water in the chilled water flow channel 142, and then the cooled working medium enters the cooled module 200 again under the driving of the circulating pump 110, so that the reciprocating circulation is realized, and the continuous heat dissipation of the electronic device is realized.

Referring again to fig. 1, in the embodiment of the present disclosure, the cooled module 200 may include a cold plate 211, and the cold plate 211 is in thermal contact with the electronic device requiring heat dissipation. It is worth mentioning that the heat conducting contact may be understood as the heat exchange between the cold plate 211 and the electronic device, either by direct contact or indirect contact. Be provided with the runner in the cold plate 211, the both ends of cold plate 211 runner communicate with cooling module 100 respectively, and the working medium can get into in the cold plate 211 by the one end of cold plate 211 runner and carry out the heat transfer with electronic equipment, later flows out cold plate 211 and gets back to cooling module 100 and in the cooling by the other end of cold plate 211 runner.

It should be understood that, a plurality of insert frames are usually disposed in the cabinet, in order to dissipate heat of electronic devices or modules carried by each insert frame, for each insert frame that needs to dissipate heat, the cooled module 200 may be respectively disposed with the cooled units 210 corresponding to the insert frame one by one, in this case, the heat dissipation system 1 may further include a first liquid distributor 400, where the first liquid distributor 400 is connected between the cooling module 100 and the cooled module 200, and may be configured to distribute the low-temperature working medium output by the cooling module 100 to the cooled units 210 corresponding to each insert frame.

In a specific implementation, a first flow channel and a second flow channel separated from each other may be disposed in the first liquid separator 400, where the first flow channel may include a liquid inlet 411 and a plurality of liquid outlets 412, the liquid inlet 411 of the first flow channel is communicated with the circulating pump 110 of the cooling module 100, and each liquid outlet 412 of the first flow channel is connected to a liquid inlet of each cooled unit 210; the second flow channel may include a plurality of liquid inlets 421 and a liquid outlet 422, each liquid inlet 421 of the second flow channel is connected to a liquid outlet of each cooled unit 210, and the liquid outlet 422 of the second flow channel is communicated with the heat exchanger (the air-cooled heat exchanger 120 or the liquid-cooled heat exchanger) of the cooling module 100. The number of the liquid outlets 412 of the first flow channel and the number of the liquid inlets 421 of the second flow channel may be not less than the number of the cooled units 210, so as to ensure the heat dissipation effect of each insert frame inside the cabinet. When the cooled unit 210 is connected, the outlet 412 of the first flow path and the inlet 421 of the second flow path may be closed by valves, or may be blocked by some sealing structures, so as to prevent the working medium in the first liquid separator 400 from leaking.

When the heat dissipation system 1 is in operation, the circulation pump 110 drives the low-temperature working medium to enter the first liquid separator 400 from the liquid inlet 411 of the first flow channel, and then the low-temperature working medium is distributed to each cooled unit 210 from each liquid outlet 412 of the first flow channel, and after the cooled unit 210 exchanges heat with the corresponding electronic device in the insert frame, the low-temperature working medium returns to the first liquid separator 400 through each liquid inlet 421 of the second flow channel, and then enters the heat exchanger of the cooling module 100 from the liquid outlet 422 of the second flow channel for cooling. It can be seen that the working medium flowing in the first flow channel is a low-temperature working medium, the working medium flowing in the second flow channel is a high-temperature working medium, and in order to reduce the heat conduction between the high-temperature working medium in the second flow channel and the low-temperature working medium in the first flow channel, the first flow channel and the second flow channel can be arranged in a heat insulation manner, for example, a heat insulation material can be arranged between the first flow channel and the second flow channel, or the peripheries of the first flow channel and the second flow channel can be respectively provided with a heat insulation material. It is understood that, when the first flow channel and the second flow channel are cavities opened inside the first liquid separator 400, the first liquid separator 400 may be made of a material having relatively poor thermal conductivity.

In addition, in some cases, in order to improve the integration of the cabinet, a plurality of electronic devices may be disposed on the insertion frame, and therefore, in order to achieve heat dissipation of each electronic device disposed on the insertion frame, the cooled unit 210 may include a plurality of cold plates 211, and the cold plates 211 may be in one-to-one heat conductive contact with each electronic device. At this time, the cooled unit 210 may further include a second liquid separator 212, and the second liquid separator 212 may be used to distribute the working medium distributed into the cooled unit 210 by the first liquid separator 400, so that the working medium can enter each cold plate 211 to dissipate heat of the corresponding electronic device.

Similar to the first liquid separator 400, the second liquid separator 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 flow channel communicates with one of the liquid outlets 412 of the first flow channel of the first liquid separator 400, and each liquid outlet 2122 of the third flow channel is connected to one end of each flow channel of the cold plates 211; the fourth flow passage may include a plurality of liquid inlets 2123 and a liquid outlet 2124, each liquid inlet 2123 of the fourth flow passage is connected to the other end of each flow passage of the cold plate 211, and the liquid outlet 2124 of the fourth flow passage is connected to one of the liquid inlets 421 of the second flow passage of the first liquid separator 400. It is 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. The number of the liquid outlets 2122 of the third flow passage and the number of the liquid inlets 2123 of the fourth flow passage may be not less than the number of the cooling plates 211 in the unit 210 to ensure the heat dissipation effect for each electronic device. When the cold plate 211 is connected, the liquid outlet 2122 with the multiple third flow channels and the liquid inlet 2123 with the multiple fourth flow channels may be closed by valves, or may be blocked by some sealing structures, so as to prevent the working medium in the second liquid separator 212 from leaking.

The working fluid in the first flow channel of the first liquid separator 400 is distributed to the second liquid separator 212 of each cooled unit 210 through each liquid outlet 412, then distributed to each cold plate 211 through each liquid outlet 2123 of the third flow channel, and after the cold plate 211 exchanges heat with the corresponding electronic device, returns to the second liquid separator 212 through each liquid inlet 2123 of the fourth flow channel, and then returns to the second flow channel of the first liquid separator 400 through the liquid outlet 2124 of the fourth flow channel. Similarly, since the working medium flowing in the third flow channel is a low-temperature working medium, and the working medium flowing in the fourth flow channel is a high-temperature working medium, in order to reduce the heat conduction between the high-temperature working medium in the fourth flow channel and the low-temperature working medium in the third flow channel, the third flow channel and the fourth flow channel may be arranged in a heat-insulating manner, and the specific arrangement manner may refer to the description of the first liquid separator 400, which is not described herein again.

It should be noted that, during the installation, use and maintenance of the heat dissipation system 1, the fluid injection installation of the initial working medium, the plugging and unplugging of various connection joints during the middle use, the aging and damage of the later-stage circulation loop, the refilling of the working medium during the maintenance, and other scenes, the existing working medium in the heat dissipation system 1 may leak slowly due to the small gap caused by the incomplete process sealing, and may also evaporate due to the long-term operation of the heat dissipation system 1. When the working medium in the heat dissipation system 1 cannot be supplemented in time, the heat dissipation performance of the whole heat dissipation system 1 is remarkably reduced. In addition, the shortage of the working medium can also cause the idle running phenomenon of the circulating pump of the cooling module 100, so that the efficiency of the circulating pump 110 can be reduced, and the service life of the circulating pump 110 can be affected due to the generation of large noise. 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 real requirement to supplement the working medium in the heat dissipation system 1 in time.

Based on this, in this application embodiment, the cooling system can also include the fluid infusion device that is used for supplementing working medium, utilizes this fluid infusion device can compensate because working medium evaporates the working medium and evaporates, the working medium that causes is not enough to improve cooling system's heat dispersion, realize the good heat dissipation to electronic equipment, ensure electronic equipment's normal work. The fluid replacement device will be specifically described below.

The fluid infusion device 500 may include a fluid infusion tank 510 and a quick coupling 520, wherein the quick coupling 520 may include a female head 521 and a male head (not shown in the figure) that are engaged with each other, the female head 521 of the quick coupling 520 may be connected to the fluid infusion tank 510, and the male head of the quick coupling 520 may be connected to a circulation loop of a heat dissipation system, so that the fluid infusion tank 510 may be connected to the circulation loop of the heat dissipation system by engaging the male head with the female head 521, so that the fluid infusion tank may supplement a working medium to the heat dissipation system in time.
