Description

Technical Field

[0001] The present disclosure relates to the field of computer heat dissipation, and in particular to a liquid cooling source system and a server capable of realizing heating, energy storage and heat dissipation. Background Art

[0002] A server is a high-performance computer that acts as a node in a network and stores and processes 80% of the data and information on the network. Its components include processors, hard disks, memory, system buses, etc., which are similar to general computer architectures. However, due to the need to provide highly reliable services, it has higher requirements in terms of processing power, stability, reliability, security, scalability, and manageability. With the development of information technology, cloud computing and big data are gradually entering people's lives, and with the improvement of server computing and processing capabilities, the heat generated by chips is also increasing at an alarming rate.

[0003] In traditional technology, air cooling or water cooling plus air cooling is generally used for heat dissipation of servers. However, the water cooling system takes up a large space and is prone to water leakage when installed carelessly or with poor materials, thereby damaging the internal parts of the server. In order to solve the above problems, a Chinese patent application numbered CN201820092164.5 discloses a supercomputer cooling system, which includes an evaporator, a compressor, a condenser, an expansion valve, an intermediate heat exchanger, a liquid metal pump, and a collector attached to the cooling component of the supercomputer.

[0004] However, the structural design of the above cooling system has the following problems during use:

[0005] The above-mentioned cooling system cools the components to be cooled in the computer through a liquid metal circulation loop, and cools the liquid metal in the liquid metal circulation loop through a refrigerant circulation loop. However, since the liquid metal circulation loop of the system is directly connected in series with the components to be cooled, that is, the heat dissipation loop of the system is relatively single, the heat dissipation effect is poor and the energy consumption is low. On the other hand, the above-mentioned cooling system has no heating loop. For equipment where the cooling temperature should not be too low, the above-mentioned system cannot precisely control the temperature of the coolant entering the components to be cooled in a targeted manner to achieve an effective protection mechanism, that is, the compatibility with the equipment use environment is poor.

[0006] Therefore, there is an urgent need for a heat dissipation system with better heat dissipation effect, low energy consumption, and adaptability to different usage environments of the equipment. Summary of the invention

[0038] The present disclosure provides a liquid cooling source system capable of realizing heating, energy storage and heat dissipation, comprising a compression mechanism, a cooling mechanism and a heating mechanism, wherein the compression mechanism comprises a compressor, a first heat exchanger, a throttling expander and a second heat exchanger, wherein the compressor, the first heat exchanger, the throttling expander and the second heat exchanger are sequentially connected end to end, and the compressor is used to compress the refrigerant and make the refrigerant pass through the first heat exchanger, the throttling expander and the second heat exchanger in sequence; the cooling mechanism comprises a first pressure pump and a cold energy storage component, wherein the first pressure pump, the second heat exchanger The first pressure pump is also used to communicate with the liquid outlet of the device, and the cold energy storage component is also used to communicate with the liquid inlet of the device to form a cooling circuit through which the coolant passes. A cold energy storage medium is arranged in the cold energy storage component.

Furthermore, since a cold energy storage medium is provided in the cold energy storage component, according to the phase change principle of the cold energy storage medium, the heat absorption or heat dissipation of the cold energy storage medium can increase or decrease the temperature of the coolant, so as to ensure that the coolant entering the equipment from the cold energy storage device is maintained in a certain temperature range, and the efficient and reliable operation of the heat dissipation system is ensured, so that the heat dissipation effect is better and the energy consumption of the system is reduced; for equipment where the cooling temperature should not be too low, when the temperature of the coolant entering the equipment is too low due to the low ambient temperature, the heating mechanism can be started to heat the cooling circuit of the cooling mechanism, so that the temperature of the coolant entering the equipment is increased, so as to quickly realize the heating function of the system, which is more suitable for different use environments of the equipment.

[0040] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0041] like Figure 1 and Figure 2 As shown, a liquid cooling source system 10 capable of realizing heating, energy storage and heat dissipation in one embodiment includes a compression mechanism 100, a cooling mechanism 200 and a heating mechanism 300, wherein the compression mechanism 100 includes a compressor 110, a first heat exchanger 120, a throttling expander 130 and a second heat exchanger 140, wherein the compressor 110, the first heat exchanger 120, the throttling expander 130 and the second heat exchanger 140 are connected end to end in sequence, and the compressor 110 is used to compress the refrigerant and pass the refrigerant through the first heat exchanger 120, the throttling expander 130 and the second heat exchanger 140 in sequence, so that the refrigerant of the compression mechanism 100 exchanges heat with the coolant of the cooling mechanism 200 at the second heat exchanger 140. Specifically, the first heat exchanger 120 includes a condensing tank 121 and a first heat exchange tank 122. The condensing tank 121 is used to release heat by condensing the refrigerant, and the first heat exchange tank 122 is used to exchange heat between the coolant passing through the first heat exchange tank 122 and the refrigerant in the condensing tank 121. The second heat exchanger 140 includes an evaporating tank 141 and a second heat exchange tank 142. The evaporating tank 141 is used to absorb heat by evaporating the refrigerant, and the second heat exchange tank 142 is used to exchange heat between the coolant in the second heat exchange tank 142 and the refrigerant in the evaporating tank 141.

[0042] The cooling mechanism 200 includes a first pressure pump 210 and a cold energy storage component 220. The first pressure pump 210, the second heat exchanger 140 and the cold energy storage component 220 are connected in sequence, that is, the first pressure pump 210 and the cold energy storage component 220 are connected to the second heat exchange box 142 of the second heat exchanger 140, respectively. The first pressure pump 210 is also used to communicate with the liquid outlet of the device 10a, and the cold energy storage component 220 is also used to communicate with the liquid inlet of the device 10a to form a cooling circuit through which the coolant passes. The cold energy storage component 220 is provided with a cold energy storage medium. When the coolant flows into the cold energy storage component 220 after heat exchange with the refrigerant in the second heat exchanger 140, the cold energy storage medium keeps the temperature of the coolant constant. Specifically, the cold energy storage medium absorbs or releases heat during the phase change process, thereby keeping the coolant flowing into the device 10a within a certain temperature range to ensure stable and reliable operation of the system.

[0043] The heating mechanism 300 corresponds to the cooling mechanism 200. The heating mechanism 300 is used to heat the coolant of the cooling mechanism 200 to increase the temperature of the coolant entering the device 10a, thereby increasing the temperature of the coolant at a high speed to adapt to different use environments of the device 10a.

[0044] In this embodiment, the heat dissipation system mainly includes the coupling of three mechanisms, the external system is a compression refrigeration mechanism, the internal system is a cooling mechanism 200 connected to the device 10a box, and the heating mechanism 300 is arranged in parallel with the cooling mechanism 200. The device 10a is cooled by multiple loops, so that the heat dissipation effect is better and the energy consumption is low. At the same time, the temperature of the coolant entering the device 10a can be accurately controlled to achieve an effective protection mechanism. Specifically, the compressor 110 of the compression mechanism 100 compresses the refrigerant into a high-temperature and high-pressure gas, which enters the throttling expander 130 for throttling and reducing the pressure after being condensed by the first heat exchanger 120, forming a low-temperature and low-pressure refrigerant that enters the second heat exchanger 140 to exchange heat with the coolant of the cooling mechanism 200. The refrigerant absorbs heat and evaporates, and then returns to the compressor 110 to enter the next refrigeration cycle. Synchronously, the coolant in the cooling mechanism 200 enters the second heat exchanger 140 under the action of the first pressure pump 210, and the coolant and the refrigerant exchange heat in the second heat exchanger 140, so that the coolant temperature is reduced and then flows through the device 10a and dissipates heat to the device 10a. After the heat exchange with the device 10a, the coolant temperature increases and finally returns to the second heat exchanger 140 for a new round of heat exchange with the refrigerant.

[0045] Furthermore, a cold energy storage component 220 is further provided in the circuit between the device 10a and the second heat exchanger 140. A cold energy storage medium is provided in the cold energy storage component 220. The cold energy storage medium is a phase change material (such as wax, fatty acid, paraffin, polyethylene glycol, etc.). The cold energy storage medium can release heat or absorb heat during phase change, so that the coolant flowing through the cold energy storage component 220 is maintained within a certain range, so as to ensure the stability of the coolant temperature entering the device 10a of the cooling system at different ambient temperatures, and ensure efficient and reliable operation of the system.

[0046] Furthermore, when the device 10a is in a harsh environment with low temperature, the temperature of the coolant in the cooling circuit is low, and the cooling temperature of the device 10a should not be too low. This is because if the temperature of the device 10a is too low, it will affect its performance. The time required to simply rely on the operation of the device 10a to make the internal temperature of the device 10a reach a suitable range, or to increase the temperature of the coolant through the phase change of the cold storage energy storage component 220, is relatively long, and may even take several hours, so that the efficiency of the device 10a in this time period is relatively slow. Therefore, it is necessary to directly heat the coolant in the cooling circuit through the heating mechanism 300. When the temperature of the coolant entering the device 10a is too low, the compression mechanism 100 is turned off and the heating mechanism 300 and the cooling mechanism 200 are started at this time. The heating mechanism 300 heats the coolant in the cooling circuit so that the coolant has a higher temperature when flowing through the device 10a. In this way, the rapid heating function of the system is realized, so that the device 10a can operate within a suitable temperature range, and the compatibility of the heat dissipation system for the device 10a in different environments is improved.

[0047] In the above-mentioned liquid cooling source system 10 that can realize heating, energy storage and heat dissipation, the compressor 110 compresses the refrigerant to form a high-temperature and high-pressure gas, and sequentially passes through the first heat exchanger 120 for condensation and heat release and the throttling expander 130 for throttling and pressure reduction, so that the refrigerant entering the second heat exchanger 140 is low-temperature and low-pressure. Since the second heat exchanger 140 is respectively connected to the first pressure pump 210 and the cold storage and energy storage component 220, the coolant of the cooling mechanism 200 exchanges heat with the refrigerant of the second heat exchanger 140, and the coolant after heat exchange flows into the device 10a to dissipate heat from the device 10a. Furthermore, since a cold energy storage medium is provided in the cold energy storage component 220, according to the phase change principle of the cold energy storage medium, the heat absorption or heat dissipation of the cold energy storage medium can increase or decrease the temperature of the coolant, so as to ensure that the coolant entering the device 10a from the cold energy storage device is kept within a certain temperature range, and the efficient and reliable operation of the heat dissipation system is ensured, so that the heat dissipation effect is better and the energy consumption of the system is reduced; for the device 10a whose cooling temperature should not be too low, when the temperature of the coolant entering the device 10a is too low due to the low ambient temperature, the heating mechanism 300 can be started to heat the cooling circuit of the cooling mechanism 200, so that the temperature of the coolant entering the device 10a is increased, so as to quickly realize the heating function of the system, which is more suitable for different use environments of the device 10a.

[0048] It should be noted that in one of the embodiments, the cold energy storage component can be eliminated and the cold energy storage medium can be retained. The cold energy storage medium runs with the cooling circuit of the cooling mechanism, which can reduce the space occupied by the cold energy storage component while ensuring the efficient operation of the heat dissipation system.

[0049] like Figure 2 As shown, in one embodiment, the heating mechanism 300 is a heating water tank, the second heat exchanger 140 is a wire tube heat exchanger, the heating mechanism 300 corresponds to the second heat exchanger 140, and the heating mechanism 300 is used to heat the second heat exchanger 140 to increase the temperature of the coolant entering the device 10a. In this embodiment, the heating mechanism 300 adopts a heating water tank, the second heat exchanger 140 is a wire tube heat exchanger, and when the coolant in the cooling circuit flows through the second heat exchange box 142 of the second heat exchanger 140, the heating water tank heats the second heat exchange box 142, so that the temperature of the coolant in the cooling mechanism 200 increases when passing through the wire tube heat exchanger, thereby making the temperature of the coolant higher when entering the device 10a, so as to ensure that the device 10a operates within a normal temperature range.

[0050] like Figure 1 and Figure 3As shown, in one embodiment, the heating mechanism 300 includes a third heat exchanger 310, a second pressure pump 320 and a first heater 330, the third heat exchanger 310 is respectively connected to the first pressure pump 210 and the second heat exchanger 140, the second pressure pump 320 is connected to the first heater 330, the first heater 330 is also connected to the pipeline between the first pressure pump 210 and the third heat exchanger 310, the second pressure pump 320 is also connected to the pipeline between the third heat exchanger 310 and the second heat exchanger 140, and the first heater 330 is used to heat the third heat exchanger 310. In this embodiment, the heating mechanism 300 is connected in parallel with the cooling mechanism 200. When the temperature of the coolant entering the device 10a is too low, the compression mechanism 100 is turned off, the heating mechanism 300 and the cooling mechanism 200 are started, and the third heat exchanger 310 is heated by the first heater 330. Specifically, the first heater 330 heats the heat exchange box of the third heat exchanger so that the temperature of the coolant increases when it flows through the third heat exchanger 310, thereby making the temperature of the coolant higher when it enters the device 10a, ensuring that the device 10a operates within a suitable range. Furthermore, the first heater 330 uses a PTC heater, and the second pressure pump 320 is a water pump, which provides power for the heating mechanism 300 so that the coolant can pass through the third heat exchanger 310.

[0051] like Figure 3 As shown, in one embodiment, the heating mechanism 300 further includes a second heater 340, the second heater 340 is connected to the second heat exchanger 140, and the second heater 340 is used to heat the second heat exchanger 140. In this embodiment, the heating mechanism 300 includes a first heater 330 and a second heater 340, and the second heater 340 is used to heat the second heat exchanger 140, that is, the second heater 340 heats the second heat exchange box 142 of the second heat exchanger 140, so that the temperature of the coolant increases when flowing through the second heat exchanger 140. Through the cooperation of the first heater 330 and the second heater 340, the temperature of the coolant in the cooling circuit increases faster. Further, the second heater 340 is a PTC heater.

[0052] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the liquid cooling source system 10 that can realize heating, energy storage and heat dissipation also includes a waste heat recovery mechanism 400, and the waste heat recovery mechanism 400 includes a first flow valve 410, a second flow valve 420, a first recovery pipe 430 and a second recovery pipe 440. The first flow valve 410 is installed in the cooling circuit of the cooling mechanism 200, the first recovery pipe 430 is respectively connected to the first flow valve 410 and the first heat exchanger 120, the second recovery pipe 440 is respectively connected to the first heat exchanger 120 and the cooling circuit of the cooling mechanism 200, and the second flow valve 420 is installed on the second recovery pipe 440 or the cooling circuit of the cooling mechanism 200. In this embodiment, when the cooling circuit is running, the coolant passes through the first flow valve 410, and the first flow valve 410 diverts the coolant. A part of the coolant enters the device 10a to dissipate the heat of the device 10a, and the other part flows into the first heat exchanger 120 through the first recovery pipe 430, that is, enters the first heat exchange box 122 of the first heat exchanger 120, and exchanges heat with the high-temperature and high-pressure gas of the condenser box 121 of the first heat exchanger 120 passed by the compressor 110. Then the coolant returns to the cooling circuit through the second recovery pipe 440 and the second flow valve 420 for the next cycle. In this way, the flow distribution of the coolant by the waste heat recovery mechanism 400 can meet the cooling capacity of the second heat exchanger 140 and the cold and energy storage component 220 and the heat of the device 10a and the first heat exchanger 120 for effective heat exchange, thereby reducing energy consumption.

[0053] like Figure 1 and Figure 3 As shown, in one embodiment, the second flow valve 420 is a two-way valve, and the second flow valve 420 is installed in the second recovery pipe 440. In this embodiment, the second flow valve 420 is a two-way valve, and the second flow valve 420 is installed in the second recovery pipe 440, and the flow rate of the coolant entering the cooling circuit is controlled by the second flow valve 420.

[0054] In one embodiment, the second flow valve is a three-way valve, and the second flow valve is installed on the pipeline between the first pressure pump and the device. In this embodiment, the second flow valve is installed on the pipeline between the first pressure pump and the device, and the second flow valve is a three-way valve, so that the coolant flowing out of the second recovery pipeline passes through the second flow valve, merges with the coolant flowing out of the device, and then flows into the first pressure pump together for the next cycle.

[0055] like Figure 1 and Figure 3As shown, in one embodiment, the first flow valve 410 is a three-way valve, and the first flow valve 410 is installed on the pipeline between the device 10a and the cold energy storage component 220. In this embodiment, the first flow valve 410 is installed on the pipeline between the device 10a and the cold energy storage component 220, and the first flow valve 410 is a three-way valve. The coolant flowing out of the cold energy storage component 220 is split through the first flow valve 410, a part of which enters the device 10a to dissipate the heat of the device 10a, and the other part flows into the first heat exchanger 120 through the first pipeline to exchange heat with the high-temperature and high-pressure refrigerant of the first heat exchanger 120.

[0056] like Figure 1 As shown, in one embodiment, the compression mechanism 100 further includes a first liquid reservoir 150, and the first liquid reservoir 150 is respectively connected to the first heat exchanger 120 and the throttling expander 130. In this embodiment, the compressor 110 compresses the refrigerant into a high-temperature and high-pressure gas, and the refrigerant enters the first heat exchanger 120 and condenses to form a low-temperature and high-pressure liquid, and then passes through the throttling expander 130 for throttling and depressurization, so that the refrigerant forms a low-temperature and low-pressure liquid. In this process, the first liquid reservoir 150 stores excess liquid refrigerant for the next cycle.

[0057] like Figure 1 As shown, in one embodiment, the cooling mechanism 200 further includes a second liquid reservoir 230, and the second liquid reservoir 230 is respectively connected to the first pressure pump 210 and the second heat exchanger 140. In this embodiment, the second liquid reservoir 230 stores the coolant. When the cooling mechanism 200 lacks the coolant due to leakage or other reasons, the coolant can be replenished from the second liquid reservoir 230 to ensure the normal operation of the cooling mechanism 200. On the other hand, the coolant will change in volume due to temperature changes, that is, thermal expansion and contraction. The second liquid reservoir 230 can absorb and buffer the change in the volume of the coolant caused by temperature changes, thereby maintaining the stability and reliability of the cooling mechanism 200.

[0058] like Figure 1 As shown, in one embodiment, the cooling mechanism 200 further includes an anti-reverse protection member 240, and the anti-reverse protection member 240 is used to be arranged between the first pressure pump 210 and the device 10a. In this embodiment, the anti-reverse protection member 240 is an anti-reverse valve. When the coolant flows forward in the cooling mechanism 200, the valve flap automatically opens under the action of the pressure difference, allowing the coolant to pass smoothly. When the coolant flows in the reverse direction, the valve flap is closed by the spring force, thereby preventing the coolant from flowing back.

[0059] like Figure 1As shown, in one embodiment, the cooling mechanism 200 further includes a filter 250, and the filter 250 is respectively connected to the first pressure pump 210 and the second heat exchanger 140. In this embodiment, the filter 250 is respectively connected to the first pressure pump 210 and the second heat exchanger 140 to filter impurities generated in the cooling circuit.

[0060] like Figure 4 As shown, in one embodiment, the cooling mechanism 200 further includes a condensing fan 260, and the condensing fan 260 is arranged opposite to the second heat exchanger 140. In this embodiment, the condensing fan 260 is arranged at the second heat exchanger 140, and the condensing fan 260 increases the heat exchange between the coolant in the cooling circuit and the refrigerant in the second heat exchanger 140, so that the system heat exchange efficiency is higher.

[0061] like Figure 1 As shown, in one embodiment, the liquid cooling source system 10 capable of realizing heating, energy storage and heat dissipation further includes a flow meter 500, which is installed in the cooling circuit of the cooling mechanism 200, and the flow meter 500 is used to detect the flow of the coolant passing through the cooling circuit. In this embodiment, the coolant flow of the cooling circuit is detected by the flow meter 500 to ensure that the coolant circulation amount in the cooling mechanism 200 is in a normal state, which helps to improve the overall performance and stability of the system.

[0062] The present application also provides a server, comprising the liquid cooling source system 10 capable of realizing heating, energy storage and heat dissipation as described in any of the above embodiments.

[0063] Compared with the prior art, the present invention has at least the following advantages:

[0064] In the above-mentioned liquid cooling source system 10 that can realize heating, energy storage and heat dissipation, the compressor 110 compresses the refrigerant to form a high-temperature and high-pressure gas, and sequentially passes through the first heat exchanger 120 for condensation and heat release and the throttling expander 130 for throttling and pressure reduction, so that the refrigerant entering the second heat exchanger 140 is low-temperature and low-pressure. Since the second heat exchanger 140 is respectively connected to the first pressure pump 210 and the cold storage and energy storage component 220, the coolant of the cooling mechanism 200 exchanges heat with the refrigerant of the second heat exchanger 140, and the coolant after heat exchange flows into the device 10a to dissipate heat from the device 10a. Furthermore, since a cold energy storage medium is provided in the cold energy storage component 220, according to the phase change principle of the cold energy storage medium, the heat absorption or heat dissipation of the cold energy storage medium can increase or decrease the temperature of the coolant, so as to ensure that the coolant entering the device 10a from the cold energy storage device is kept within a certain temperature range, and the efficient and reliable operation of the heat dissipation system is ensured, so that the heat dissipation effect is better and the energy consumption of the system is reduced; for the device 10a whose cooling temperature should not be too low, when the temperature of the coolant entering the device 10a is too low due to the low ambient temperature, the heating mechanism 300 can be started to heat the cooling circuit of the cooling mechanism 200, so that the temperature of the coolant entering the device 10a is increased, so as to quickly realize the heating function of the system, which is more suitable for different use environments of the device 10a.

[0065] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the attached claims.
