Description

TECHNICAL FIELD

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

[0002] A server is a high-performance computer that stores and processes 80% of the data and information on the network as a node of the network. Its structure includes processors, hard disks, memories, system buses, etc., and is similar to the architecture of a general-purpose computer. However, due to the need to provide high-reliability services, it has higher requirements in terms of processing capacity, stability, reliability, security, scalability, and manageability. With the development of information technology, cloud computing and big data are gradually entering people's lives, and the improvement of server computing processing capacity and the heat dissipation of chips are also increasing at an alarming rate.

[0003] In the traditional technology, the heat dissipation of the server is generally achieved by air cooling or water cooling plus air cooling. However, the water cooling system occupies a large space and is prone to leakage when installed carelessly or with poor materials, thereby damaging the internal parts of the server. In order to solve the above problems, a supercomputer cooling system is disclosed in Chinese Patent No. CN201820092164.5, which includes an evaporator, a compressor, a condenser, an expansion valve, an intermediate heat exchanger, a liquid metal pump, and a heat collector attached to the components to be cooled in the supercomputer.

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

[0005] The above cooling system cools the components to be cooled in the supercomputer 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, the heat dissipation circuit of the system is relatively simple, resulting in poor heat dissipation effect and low energy consumption. On the other hand, the above cooling system does not have a heating circuit, and for equipment whose cooling temperature should not be too low, the above system cannot accurately control the temperature of the cooling liquid entering the components to be cooled to achieve effective protection mechanism, i.e., the universality of the equipment usage environment is poor.

[0006] Therefore, there is an urgent need for a heat dissipation system that has good heat dissipation effect, low energy consumption, and can adapt to different usage environments of equipment. Invention content

[0027] Compared with the prior art, the present disclosure has at least the following advantages:

[0028] 1. The aforementioned liquid cooling source system, capable of heating, energy storage, and heat dissipation, uses a compressor to compress the refrigerant into a high-temperature, high-pressure gas. This gas then passes through a first heat exchanger for condensation and heat release, and a throttling expansion device for pressure reduction, ensuring that the refrigerant entering the second heat exchanger is at a low temperature and low pressure. Since the second heat exchanger is connected to both the first pressure pump and the cold storage energy storage device, the coolant in the cooling mechanism exchanges heat with the refrigerant in the second heat exchanger. The cooled liquid then flows into the equipment to dissipate heat. Furthermore, because the cold storage energy storage device contains a cold storage medium, based on the phase change principle of the cold storage medium, the absorption or dissipation of heat by the cold storage medium can raise or lower the temperature of the coolant. This ensures that the coolant entering the equipment from the cold storage energy storage device remains within a certain temperature range, guaranteeing the efficient and reliable operation of the heat dissipation system, resulting in better heat dissipation and reduced system energy consumption.

When the ambient temperature is too low and the temperature of the coolant entering the equipment is too low, the heating mechanism can be activated to heat the cooling circuit of the cooling mechanism, so as to raise the temperature of the coolant entering the equipment, thereby quickly realizing the heating function of the system and making it more suitable for different operating environments of the equipment.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0038] The 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. The compression mechanism comprises a compressor, a first heat exchanger, a throttling expander and a second heat exchanger, which are sequentially connected end to end. The compressor is used to compress 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 storage energy storage member. The first pressure pump, the second heat exchanger and the cold storage energy storage member are sequentially connected. The first pressure pump is also used to communicate with the liquid outlet end of the equipment. The cold storage energy storage member is also used to communicate with the liquid inlet end of the equipment to form a cooling circuit through which the cooling liquid passes. The cold storage energy storage member is provided with a cold storage energy storage medium. When the cooling liquid flows into the cold storage energy storage member after heat exchange with the refrigerant in the second heat exchanger, the cold storage energy storage medium keeps the temperature of the cooling liquid constant. The heating mechanism corresponds to the cooling mechanism. The heating mechanism is used to heat the cooling liquid of the cooling mechanism to increase the temperature of the cooling liquid entering the equipment.

[0039] The liquid cooling source system capable of realizing heating, energy storage and heat dissipation can realize the heat dissipation of the equipment through the cooling mechanism. The compressor compresses the refrigerant to form a high-temperature and high-pressure gas, and the refrigerant sequentially passes through the first heat exchanger to be condensed and heat-dissipated and passes through the throttling expander to be throttled and pressure-reduced, so that the refrigerant entering the second heat exchanger is low-temperature and low-pressure. Since the second heat exchanger is in communication with the first pressure pump and the energy storage device respectively, the cooling liquid of the cooling mechanism exchanges heat with the refrigerant of the second heat exchanger, and the cooling liquid after heat exchange flows into the equipment to dissipate heat. Further, the energy storage device is provided with the energy storage medium. According to the phase change principle of the energy storage medium, the heat absorption or heat dissipation of the energy storage medium can increase or decrease the temperature of the cooling liquid, so as to ensure that the cooling liquid entering the equipment from the energy storage device is kept within a certain temperature range, to ensure the efficient and reliable operation of the heat dissipation system, to make the heat dissipation effect better, and to reduce the energy consumption of the system. For the equipment whose cooling temperature should not be too low, when the temperature of the cooling liquid 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 cooling liquid entering the equipment is increased, to quickly realize the heating function of the system, and to be more suitable for different use environments of the equipment.

[0040] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

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

[0042] The cooling mechanism 200 comprises a first pressure pump 210 and a cold storage energy storage member 220, the first pressure pump 210, the second heat exchanger 140 and the cold storage energy storage member 220 are sequentially communicated, that is, the first pressure pump 210 and the cold storage energy storage member 220 are respectively communicated with the second heat exchange box 142 of the second heat exchanger 140, the first pressure pump 210 is also used for being communicated with the liquid outlet end of the device 10a, and the cold storage energy storage member 220 is also used for being communicated with the liquid inlet end of the device 10a, so as to form a cooling circuit through which the cooling liquid passes, and the cold storage energy storage member 220 is provided with a cold storage energy storage medium, when the cooling liquid flows into the cold storage energy storage member 220 after being exchanged with the refrigerant in the second heat exchanger 140, the cold storage energy storage medium keeps the temperature of the cooling liquid constant. Specifically, the cold storage energy storage medium absorbs or releases heat in the phase change process, so that the cooling liquid flowing into the device 10a is kept in a certain temperature range, so as to ensure the stable and reliable operation of the system.

[0043] The heating mechanism 300 corresponds to the cooling mechanism 200, and is used for heating the cooling liquid of the cooling mechanism 200, so that the temperature of the cooling liquid entering the device 10a is increased, and then the temperature of the cooling liquid is increased at a high speed, so as to adapt to different use environments of the device 10a.

[0044] In the embodiment, the heat dissipation system mainly comprises the coupling of three mechanisms, the outer system is the compression refrigeration mechanism, the inner system is the cooling mechanism 200 connected with the device 10a box, and the heating mechanism 300 is arranged in parallel with the cooling mechanism 200, the device 10a is cooled through multiple circuits, so that the heat dissipation effect is better and the energy consumption is low, and the temperature of the cooling liquid entering the device 10a can be accurately controlled, and an effective protection mechanism is realized. Specifically, the compressor 110 of the compression mechanism 100 compresses the refrigerant into a high-temperature and high-pressure gas, which is condensed through the first heat exchanger 120 and then enters the throttling expander 130 to be throttled and decompressed, so that the low-temperature and low-pressure refrigerant enters the second heat exchanger 140 to exchange heat with the cooling liquid of the cooling mechanism 200, and the refrigerant is evaporated after absorbing heat and returns to the compressor 110 to enter the next refrigeration cycle. Synchronously, the cooling liquid in the cooling mechanism 200 enters the second heat exchanger 140 under the action of the first pressure pump 210, the cooling liquid and the refrigerant exchange heat in the second heat exchanger 140, so that the temperature of the cooling liquid is reduced and the cooling liquid flows through the device 10a and cools the device 10a, and the temperature of the cooling liquid after exchanging heat with the device 10a is increased and finally returns to the second heat exchanger 140 to exchange heat with the refrigerant again.

[0045] Further, the circuit between the device 10a and the second heat exchanger 140 is also provided with a cold storage energy storage member 220, and the cold storage energy storage member 220 is provided with a cold storage energy storage medium, which is a phase change material (such as wax, fatty acid, paraffin, polyethylene glycol, etc.). When the cold storage energy storage medium changes phase, it can release or absorb heat, so that the cooling liquid flowing through the cold storage energy storage member 220 is kept within a certain range, so as to ensure the stability of the cooling system in different environmental temperatures entering the device 10a, and ensure the efficient and reliable operation of the system.

[0046] Further, when the device 10a is in a harsh environment with a lower temperature, the cooling liquid in the cooling circuit has a lower temperature, and the cooling temperature of the device 10a should not be too low, because the temperature of the device 10a is too low, which will affect its performance. It takes a long time 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 cooling liquid by phase change of the cold storage energy storage member 220, which may even take several hours, so that the efficiency of the device 10a during this period is relatively slow. Therefore, the cooling liquid in the cooling circuit needs to be heated by the heating mechanism 300. When the temperature of the cooling liquid entering the device 10a is too low, the compression mechanism 100 is closed, and the heating mechanism 300 and the cooling mechanism 200 are started at this time. The heating mechanism 300 heats the cooling liquid in the cooling circuit, so that the cooling liquid has a higher temperature when flowing through the device 10a, so as to realize the function of rapid heating of the system, and further make the device 10a operate in a suitable temperature range, and improve the compatibility of the heat dissipation system for the device 10a in different environments.

[0047] The liquid cooling source system 10 can realize heating, energy storage and heat dissipation. The compressor 110 compresses the refrigerant to form a high-temperature and high-pressure gas, and then the refrigerant sequentially passes through the first heat exchanger 120 to be condensed and heat dissipated and passes through the throttling expander 130 to be throttled and depressurized, so that the refrigerant entering the second heat exchanger 140 is low-temperature and low-pressure. Since the second heat exchanger 140 is in communication with the first pressure pump 210 and the energy storage and energy storage member 220 respectively, the cooling liquid of the cooling mechanism 200 exchanges heat with the refrigerant of the second heat exchanger 140, and the cooled cooling liquid flows into the equipment 10a to dissipate heat. Further, since the energy storage and energy storage member 220 is provided with an energy storage and energy storage medium, according to the phase change principle of the energy storage and energy storage medium, the heat absorption or heat dissipation of the energy storage and energy storage medium can increase or decrease the temperature of the cooling liquid, so as to ensure that the cooling liquid entering the equipment 10a from the energy storage and energy storage device is kept in a certain temperature range, guaranteeing the efficient and reliable operation of the heat dissipation system, making the heat dissipation effect better, and reducing the energy consumption of the system. For the equipment 10a whose cooling temperature should not be too low, when the temperature of the cooling liquid entering the equipment 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 cooling liquid entering the equipment 10a is increased, so as to quickly realize the heating function of the system, and be more suitable for different use environments of the equipment 10a.

[0048] It should be noted that in one of the embodiments, the energy storage and energy storage member can be cancelled, and the energy storage and energy storage medium is retained. The energy storage and energy storage medium operates with the cooling circuit of the cooling mechanism, which can not only guarantee the efficient operation of the heat dissipation system, but also reduce the space occupied by the energy storage and energy storage member.

[0049] As shown in Figure 2 In one of the embodiments, 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 for heating the second heat exchanger 140 to increase the temperature of the cooling liquid entering the equipment 10a. In this embodiment, the heating mechanism 300 is a heating water tank, the second heat exchanger 140 is a wire tube heat exchanger, and when the cooling liquid in the cooling circuit flows through the second heat exchanger 140, the heating water tank heats the second heat exchanger 140, so that the temperature of the cooling liquid in the cooling mechanism 200 is increased when the cooling liquid passes through the wire tube heat exchanger, and then the temperature of the cooling liquid entering the equipment 10a is higher, so as to ensure that the equipment 10a operates in a normal temperature range.

[0050] As shown in Figure 1 and Figure 3As shown, in one embodiment, the heating mechanism 300 comprises a third heat exchanger 310, a second pressure pump 320 and a first heater 330, the third heat exchanger 310 is in communication with the first pressure pump 210 and the second heat exchanger 140 respectively, the second pressure pump 320 is in communication with the first heater 330, the first heater 330 is also in communication with the pipeline between the first pressure pump 210 and the third heat exchanger 310, the second pressure pump 320 is also in communication with 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 cooling liquid entering the device 10a is too low, the compression mechanism 100 is closed, the heating mechanism 300 and the cooling mechanism 200 are started, and the first heater 330 is used to heat the third heat exchanger 310. Specifically, the first heater 330 heats the heat exchange box of the third heat exchanger, so that the temperature of the cooling liquid increases when flowing through the third heat exchanger 310, and then the temperature of the cooling liquid entering the device 10a is higher, which ensures that the device 10a operates in a suitable range. Further, the first heater 330 is a PTC heater, and the second pressure pump 320 is a water pump, which provides power for the heating mechanism 300, so that the cooling liquid can pass through the third heat exchanger 310.

[0051] As shown, Figure 3 in one embodiment, the heating mechanism 300 further comprises a second heater 340, the second heater 340 is connected with 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 comprises the first heater 330 and the second heater 340, and the second heater 340 is used to heat the second heat exchanger 140, i.e. the second heater 340 heats the second heat exchange box 142 of the second heat exchanger 140, so that the temperature of the cooling liquid increases when flowing through the second heat exchanger 140, and the temperature increasing rate of the cooling liquid in the cooling circuit is faster through the cooperation of the first heater 330 and the second heater 340. Further, the second heater 340 is a PTC heater.

[0052] As shown, Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the liquid cooling source system 10 capable of heating, storing energy, and dissipating heat further includes a waste heat recovery mechanism 400. 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 connected to the first flow valve 410 and the first heat exchanger 120, respectively. The second recovery pipe 440 is connected to the first heat exchanger 120 and the cooling circuit of the cooling mechanism 200, respectively. 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 coolant is running in the cooling circuit, it passes through the first flow valve 410, which divides the coolant. Part of the coolant enters the device 10a to dissipate heat from the device 10a, while the other part flows through the first recovery pipe 430 into the first heat exchanger 120, that is, into the first heat exchange box 122 of the first heat exchanger 120, where it exchanges heat with the high-temperature and high-pressure gas from the compressor 110 that enters the condenser box 121 of the first heat exchanger 120. 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 effectively meet the cooling capacity requirements of the second heat exchanger 140 and the cold storage device 220, as well as the heat requirements of the device 10a and the first heat exchanger 120, 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 to control the flow rate of coolant entering the cooling circuit.

[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 equipment. In this embodiment, the second flow valve is installed on the pipeline between the first pressure pump and the equipment, 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 equipment, and flows into the first pressure pump together for the next cycle.

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

[0056] As shown in one of the embodiments, the cooling mechanism 200 further comprises a second liquid storage 230, which is in communication with the first pressure pump 210 and the second heat exchanger 140, respectively. Figure 1 As shown in one of the embodiments, the first flow valve 410 is a three-way valve, which is installed on the pipeline between the device 10a and the cold storage energy storage 220. In this embodiment, the first flow valve 410 is installed on the pipeline between the device 10a and the cold storage energy storage 220, and the first flow valve 410 is a three-way valve. The cooling liquid flowing out of the cold storage energy storage 220 is divided by the first flow valve 410, part of which enters the device 10a to cool the device 10a, and the other part flows into the first heat exchanger 120 to exchange heat with the high-temperature and high-pressure refrigerant of the first heat exchanger 120.

[0057] As shown in one of the embodiments, the cooling mechanism 200 further comprises a second liquid storage 230, which is in communication with the first pressure pump 210 and the second heat exchanger 140, respectively. Figure 1 As shown in one of the embodiments, the cooling mechanism 200 further comprises a second liquid storage 230, which is in communication with the first pressure pump 210 and the second heat exchanger 140, respectively. In this embodiment, the second liquid storage 230 stores the cooling liquid. When the cooling mechanism 200 lacks cooling liquid due to leakage or other reasons, the second liquid storage 230 can be used to supplement the cooling liquid to ensure the normal operation of the cooling mechanism 200. On the other hand, the volume of the cooling liquid changes with temperature, i.e. thermal expansion and contraction. The second liquid storage 230 can absorb and buffer the volume change of the cooling liquid caused by temperature change, thereby maintaining the stability and reliability of the cooling mechanism 200.

[0058] As shown in one of the embodiments, the cooling mechanism 200 further comprises a second liquid storage 230, which is in communication with the first pressure pump 210 and the second heat exchanger 140, respectively. Figure 1 As shown in one of the embodiments, the cooling mechanism 200 further comprises a second liquid storage 230, which is in communication with the first pressure pump 210 and the second heat exchanger 140, respectively. In this embodiment, the second liquid storage 230 stores the cooling liquid. When the cooling mechanism 200 lacks cooling liquid due to leakage or other reasons, the second liquid storage 230 can be used to supplement the cooling liquid to ensure the normal operation of the cooling mechanism 200. On the other hand, the volume of the cooling liquid changes with temperature, i.e. thermal expansion and contraction. The second liquid storage 230 can absorb and buffer the volume change of the cooling liquid caused by temperature change, thereby maintaining the stability and reliability of the cooling mechanism 200.

[0059] As shown in one of the embodiments, the cooling mechanism 200 further comprises a second liquid storage 230, which is in communication with the first pressure pump 210 and the second heat exchanger 140, respectively. Figure 1As shown in the drawings, in one of the embodiments, the cooling mechanism 200 further comprises a filter 250, which is connected with the first pressure pump 210 and the second heat exchanger 140 respectively. In this embodiment, the filter 250 is communicated with the first pressure pump 210 and the second heat exchanger 140 respectively, so as to filter the impurities generated in the cooling circuit.

[0060] As shown in the drawings, Figure 4 As shown in the drawings, in one of the embodiments, the cooling mechanism 200 further comprises a condensing fan 260, which 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 amount between the cooling liquid in the cooling circuit and the refrigerant at the second heat exchanger 140, so that the system heat exchange efficiency is higher.

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

[0062] The application further provides a server comprising the liquid cooling source system 10 capable of realizing heating, energy storage and heat dissipation according to any one of the above embodiments.

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

[0064] The liquid cooling source system 10 capable of realizing heating, energy storage and heat dissipation, the compressor 110 compresses the refrigerant to form a high-temperature and high-pressure gas, and then passes through the first heat exchanger 120 to condense and release heat and the throttling expander 130 to throttle and reduce pressure, so that the refrigerant entering the second heat exchanger 140 is low-temperature and low-pressure. Since the second heat exchanger 140 is communicated with the first pressure pump 210 and the cold storage energy storage member 220 respectively, the cooling liquid of the cooling mechanism 200 exchanges heat with the refrigerant of the second heat exchanger 140, and the cooled cooling liquid flows into the equipment 10a to dissipate heat. Further, since the cold storage energy storage medium is arranged in the cold storage energy storage member 220, according to the phase change principle of the cold storage energy storage medium, the heat absorption or heat release of the cold storage energy storage medium can increase or decrease the temperature of the cooling liquid, so as to ensure that the cooling liquid entering the equipment 10a from the cold storage energy storage device is kept in a certain temperature range, guaranteeing the efficient and reliable operation of the heat dissipation system, making the heat dissipation effect better, and reducing the energy consumption of the system. For the equipment 10a whose cooling temperature should not be too low, when the temperature of the cooling liquid entering the equipment 10a is too low due to the too 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 cooling liquid entering the equipment 10a is increased, so as to quickly realize the heating function of the system, and be more suitable for different use environments of the equipment 10a.
