[0032] Embodiment one

[0033] The present embodiment provides a modular heat dissipation system, such as Figure 1As shown, the cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5 are connected to each other so as to deliver the cooling liquid prepared by the cooling liquid preparation module 1 to the cooling liquid temperature control circulation module 5, and then realize the energy exchange between the cooling liquid and the load at the cooling liquid temperature control circulation module 5. Specifically, the cooling liquid preparation module 1 includes several cooling liquid preparation modules 1 of different specifications, and the cooling liquid preparation modules 1 of different specifications have different refrigeration capacities. The cooling liquid temperature control circulation module 5 includes a load liquid supply circulation unit 8, and the cooling liquid prepared by the cooling liquid preparation module 1 is delivered to the load liquid supply circulation unit 8 to realize the energy exchange between the cooling liquid and the load at the load liquid supply circulation unit 8. The cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5 are both independent single devices, the cooling liquid preparation module 1 is provided with a preparation liquid supply interface 3 and a preparation liquid return interface 4, the cooling liquid temperature control circulation module 5 includes a temperature control liquid supply interface 6 and a temperature control liquid return interface 7, and the load liquid supply circulation unit 8 is connected between the temperature control liquid supply interface 6 and the temperature control liquid return interface 7. When the cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5 need to be connected, the preparation liquid supply interface 3 is connected to the temperature control liquid supply interface 6, and the preparation liquid return interface 4 is connected to the temperature control liquid return interface 7, so as to deliver the cooling liquid prepared by the cooling liquid preparation module 1 to the load liquid supply circulation unit 8 of the cooling liquid temperature control circulation module 5 through the preparation liquid supply interface 3 and the temperature control liquid supply interface 6 in sequence, so that the cooling liquid exchanges energy with the load at the load liquid supply circulation unit 8. After the energy exchange with the load at the load liquid supply circulation unit 8, the cooling liquid becomes cooling hot liquid, which is delivered to the cooling liquid preparation module 1 through the temperature control liquid return interface 7 and the preparation liquid return interface 4 in sequence, and the cooling hot liquid becomes the cooling liquid again after the energy exchange at the cooling liquid preparation module 1, and then circulates in sequence to realize the heat dissipation of the load. Since the cooling liquid preparation module 1 includes several cooling liquid preparation units 2 with different refrigeration capacities, and the cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5 are quickly connected through the preparation liquid supply interface 3, the temperature control liquid supply interface 6, the preparation liquid return interface 4 and the temperature control liquid return interface 7, the user can match the cooling liquid preparation module 1 with appropriate refrigeration capacity to the cooling liquid temperature control circulation module 5 according to the heat dissipation demand of the load, that is, match the cooling liquid preparation unit 2 with appropriate refrigeration capacity to the load liquid supply circulation unit 8. When the load amount at the load liquid supply circulation unit 8 is reduced and the heat dissipation capacity of the current cooling liquid preparation unit 2 is much larger than the heat dissipation demand of the load, the user can remove the current cooling liquid preparation unit 2, select the cooling liquid preparation unit 2 with smaller refrigeration capacity and matching the heat dissipation demand of the load, and then connect the matching cooling liquid preparation unit 2 to the cooling liquid temperature control circulation module 5.The docking between the liquid supply interface 3 and the temperature-controlled liquid supply interface 6 and the rapid docking between the liquid return interface 4 and the temperature-controlled liquid return interface 7 can be achieved by using a docking hose 110, or the docking between the liquid supply interface 3 and the temperature-controlled liquid supply interface 6 and the rapid docking between the liquid return interface 4 and the temperature-controlled liquid return interface 7 can be achieved by using a male head and a female head. Preferably, the docking hose 110 is used in the present application, and the docking hose 110 has a length, which is convenient for arrangement.

[0034] The cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5 of the modular heat dissipation system of the present application are independent single-machine devices, which realizes the modular docking and separation of the cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5, matches the corresponding cooling liquid preparation unit 2 for the load liquid supply circulation unit 8, matches the cooling capacity of the cooling liquid preparation unit 2 with the heat dissipation demand of the load, improves the heat dissipation adjustment capacity of the heat dissipation system, meets the heat dissipation demand of the load, and avoids the waste of the cooling capacity. In addition, the modular docking and separation of the cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5 realizes the de-engineering design of the liquid cooling system, makes it become an independent single-machine device, avoids a large amount of construction and foundation reconstruction, reduces the construction difficulty and resource investment of the liquid cooling environment, shortens the construction period of the liquid cooling environment, and reduces the operation and maintenance difficulty of the liquid cooling system. Moreover, it can adapt to the modification of the existing air-cooled data center heat dissipation system, without large-scale construction and shutdown of the existing machine room, and can adapt to the scene of small-scale liquid cooling test environment required by scientific research, colleges and universities, and laboratories.

[0035] Since the cooling liquid preparation module 1 and the cooling liquid temperature control circulation module 5 of the modular heat dissipation system of the present application are independent single-machine devices, the modular heat dissipation system of the present application has a self-contained active refrigeration cold source design, avoids the problem that the existing large system liquid cooling product needs to be designed strictly in terms of flow resistance and thermal resistance, solves the problem of low adaptability of large systems, and can realize the best heat dissipation performance adaptation of different liquid cooling products and liquid cooling environments. In addition, the cooling liquid preparation module 1 of the present application is a mobile single-machine device, which can be flexibly moved according to the actual scene and reused in different places.

[0036] In one specific embodiment, a plurality of branches are arranged on the docking hose 110, and each branch can be connected to one cooling liquid temperature control circulation module 5. Therefore, one cooling liquid preparation module 1 can be used to dissipate heat for the loads of a plurality of cooling liquid temperature control circulation modules 5. The cooling liquid flow and the cooling liquid temperature of the plurality of branches are adjusted according to the load demand of the corresponding cooling liquid temperature control circulation module 5.

[0037] In one specific embodiment, as shown in FIG. 6, the docking hose 110 is connected to the liquid supply interface 3 and the temperature-controlled liquid supply interface 6, and the liquid return interface 4 and the temperature-controlled liquid return interface 7 are connected by a plurality of branches. Figure 2 and Figure 3As shown, the cooling liquid preparation unit 2 includes both the refrigerant refrigeration unit 9 and the natural cooling unit 10, and the refrigeration capacity of the refrigerant refrigeration unit 9 is greater than that of the natural cooling unit 10. The refrigerant refrigeration unit 9 or the natural cooling unit 10 can be selected according to the relationship between the required temperature of the cooling liquid supplied by the load liquid circulation unit 8 and the outdoor ambient temperature.

[0038] Specifically, when the required temperature of the cooling liquid supplied by the load liquid circulation unit 8 is lower than the outdoor ambient temperature, the cooling liquid supplied by the load liquid circulation unit 8 cannot be lowered to the required temperature by the outdoor ambient temperature, and therefore, the refrigerant refrigeration unit 9 needs to be used for forced refrigeration to lower the cooling liquid supplied by the load liquid circulation unit 8 to the required temperature. When the required temperature of the cooling liquid supplied by the load liquid circulation unit 8 is higher than or equal to the outdoor ambient temperature, the cooling liquid supplied by the load liquid circulation unit 8 can be cooled by the natural cooling unit 10 to lower the cooling liquid supplied by the load liquid circulation unit 8 to the required temperature.

[0039] The refrigeration capacity of the refrigerant refrigeration unit 9 of the present application is greater than that of the natural cooling unit 10. The refrigerant refrigeration unit 9 and the natural cooling unit 10 can both be connected to the cooling liquid temperature control circulation module 5 to adjust the refrigeration capacity of the cooling liquid preparation unit 2. In addition, the appropriate refrigeration unit can be selected according to the relationship between the outdoor ambient temperature and the required temperature of the cooling liquid, which not only reduces the energy consumption but also improves the energy conversion efficiency (COP) of the system.

[0040] In one specific embodiment, the refrigerant refrigeration unit 9 is a forced refrigeration unit using refrigerant. The refrigerant refrigeration unit 9 includes two operating modes, one is a compressor mode established by using a compressor 13, and the other is a refrigerant pump mode established by using a refrigerant pump 14. The refrigerant refrigeration unit 9 can be placed in the compressor mode or the refrigerant pump mode according to the size of the load and the temperature relationship.

[0041] Specifically, as shown in Figure 4 The refrigerant refrigeration unit 9 includes a gas-liquid separation device 11, a refrigerant heat exchanger 12, a compressor 13, and a refrigerant pump 14. The gas-liquid separation device 11 has a separation inlet 15, a gas outlet 16, and a gas-liquid outlet 17. The refrigerant heat exchanger 12 has a refrigerant primary side 18 and a refrigerant secondary side 19.

[0042] A compressor refrigeration circuit is established between the outlet of the refrigerant primary side 18, the separation inlet 15, the gas outlet 16, the compressor 13, and the inlet of the refrigerant primary side 18. When the refrigerant refrigeration unit 9 operates in the compressor refrigeration circuit, the operating mode of the refrigerant refrigeration unit 9 is in the compressor mode.

[0043] The refrigerant pump refrigeration circuit is established between the outlet of the refrigerant primary side 18, the separation inlet 15, the gas-liquid outlet 17, the refrigerant pump 14 and the inlet of the refrigerant primary side 18. When the refrigerant pump refrigeration circuit is in operation, the working mode of the refrigerant refrigeration unit 9 is in the refrigerant pump mode.

[0044] The inlet of the refrigerant secondary side 19 is connected to the temperature control liquid return interface 7, and the outlet of the refrigerant secondary side 19 is connected to the temperature control liquid supply interface 6. Therefore, the refrigerant of the refrigerant refrigeration unit 9 and the cooling liquid of the load liquid supply circulation unit 8 exchange energy at the refrigerant heat exchanger 12, so that the cooling liquid of the load liquid supply circulation unit 8 is cooled by the low-temperature liquid refrigerant of the refrigerant refrigeration unit 9, and the liquid refrigerant after energy exchange with the cooling liquid absorbs heat and becomes gaseous.

[0045] In the actual operation of the heat dissipation system, the size of the load of the load liquid supply circulation unit 8 changes, and therefore the temperature of the cooling liquid after energy exchange with the load also changes. When the load becomes smaller, the temperature of the cooling liquid after energy exchange with the load is not enough to change the refrigerant into a gaseous state after energy exchange with the refrigerant. At this time, the refrigerant flowing out of the refrigerant primary side 18 exists in a liquid state, and the refrigerant refrigeration unit 9 cannot be placed in the compressor mode, which can only operate in the gaseous state. Therefore, when the load is small, the refrigerant refrigeration unit 9 can be placed in the refrigerant pump mode, which allows the circulation of refrigerant in a gas-liquid state and reduces the minimum load requirement. Therefore, the modular heat dissipation system of the present application includes a controller, which is provided with a preset threshold value for determining whether the refrigerant exists in a liquid state. The preset threshold value can be a temperature value, such as the temperature value of the load, which reflects the heat dissipation capacity of the load. When the temperature value of the load is greater than the preset threshold value, i.e., when the heat dissipation capacity of the load is enough to change the refrigerant into a gaseous state after energy exchange with the cooling liquid, the controller places the refrigerant refrigeration unit 9 in the compressor mode; when the temperature value of the load is less than or equal to the preset threshold value, i.e., when the heat dissipation capacity of the load is not enough to change the refrigerant into a gaseous state after energy exchange with the cooling liquid, the controller places the refrigerant refrigeration unit 9 in the refrigerant pump mode. The preset threshold value can also be the outlet temperature value of the refrigerant primary side 18, or other indicators that can reflect the existence of liquid refrigerant.

[0046] The present application can select the compressor mode and the refrigerant pump mode of the refrigerant refrigeration unit 9 according to the outdoor ambient temperature, which not only reduces energy consumption and improves the energy conversion efficiency of the system, but also matches the refrigeration capacity of the cooling liquid preparation unit 2 with the heat dissipation demand of the load, improves the heat dissipation adjustment range of the heat dissipation system, meets the heat dissipation demand of the load, and avoids waste of refrigeration capacity.

[0047] In addition, since the refrigerant refrigeration unit 9 in the compressor mode can compress the high-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, the temperature difference between the high-temperature and high-pressure gaseous refrigerant and the medium for condensing the same is large, so the refrigeration efficiency of the refrigerant refrigeration unit 9 in the compressor mode is high. Among them, in the refrigerant pump mode, the medium after energy exchange with the gaseous refrigerant is cooled by the heat dissipation fan, and since there is no compressor 13 to compress the gaseous refrigerant, when the outdoor ambient temperature is high, the temperature difference between the gaseous refrigerant in the refrigerant pump mode and the medium for condensing the same is small, resulting in low refrigeration efficiency, or even no refrigeration. Therefore, when the outdoor ambient temperature is high, the refrigerant refrigeration unit 9 automatically switches to the compressor mode to ensure the normal operation of the refrigerant refrigeration unit 9 and ensure the heat dissipation demand of the load.

[0048] In one embodiment, as shown in FIG. 1, the refrigerant refrigeration unit 9 is connected to the heat dissipation device 2 through the refrigerant pump mode and the compressor mode. Figure 4 As shown in FIG. 1, the outlet of the refrigerant primary side 18 is connected with the separation inlet 15 of the gas-liquid separation device 11 through a refrigerant return liquid inlet switch 20, and the outlet of the refrigerant primary side 18 and the refrigerant return liquid inlet switch 20 are provided with a refrigerant inlet temperature sensor 108 and a refrigerant inlet pressure sensor 109. The refrigerant inlet temperature sensor 108 is used to collect the outlet temperature of the refrigerant primary side 18, and the refrigerant inlet pressure sensor 109 is used to collect the outlet pressure of the refrigerant primary side 18.

[0049] The gas outlet 16 of the gas-liquid separation device 11 and the inlet of the condensing mechanism 24 are sequentially provided with a compressor inlet switch 21, a refrigerant return liquid inlet drying filter 22, a compressor 13, and a compressor outlet check valve 23, and the outlet of the compressor outlet check valve 23 and the inlet of the condensing mechanism 24 are provided with a condensing inlet pressure sensor 102 and a condensing inlet temperature sensor 103. The condensing inlet pressure sensor 102 is used to collect the inlet pressure of the condensing mechanism 24, and the condensing inlet temperature sensor 103 is used to collect the inlet temperature of the condensing mechanism 24.

[0050] The outlet of the condensing mechanism 24 is sequentially provided with a condensing outlet filter 25, a condensing outlet switch 26, a refrigerant heat exchange inlet check valve 27 and a throttling mechanism 28 between the inlet of the refrigerant primary side 18, and is provided with a condensing outlet temperature sensor 105 and a condensing outlet pressure sensor 104 between the outlet of the condensing mechanism 24 and the inlet of the refrigerant liquid return inlet dry filter 22, and is provided with a refrigerant heat exchange inlet pressure sensor 107 and a refrigerant heat exchange inlet temperature sensor 106 between the outlet of the throttling mechanism 28 and the inlet of the refrigerant primary side 18, the condensing outlet pressure sensor 104 is used to collect the outlet pressure of the condensing mechanism 24, the condensing outlet temperature sensor 105 is used to collect the outlet temperature of the condensing mechanism 24, the refrigerant heat exchange inlet temperature sensor 106 is used to collect the inlet temperature of the refrigerant primary side 18, and the refrigerant heat exchange inlet pressure sensor 107 is used to collect the inlet pressure of the refrigerant primary side 18.

[0051] The gas-liquid outlet 17 of the gas-liquid separation device 11 is sequentially provided with a refrigerant inlet switch 29 and a refrigerant pump inlet check valve 30 between the inlet of the condensing mechanism 24, and the refrigerant inlet switch 29 and the refrigerant pump inlet check valve 30 are provided in parallel with the compressor inlet switch 21, the refrigerant liquid return inlet dry filter 22, the compressor 13, the compressor outlet check valve 23.

[0052] The outlet of the condensing outlet filter 25 is sequentially provided with a refrigerant pump inlet switch 31 and a refrigerant pump 14 between the inlet of the refrigerant heat exchange inlet check valve 27, and the refrigerant pump inlet switch 31 and the refrigerant pump 14 are provided in parallel with the condensing outlet switch 26.

[0053] As shown in Figure 5 When the controller controls the compressor inlet switch 21 and the condensing outlet switch 26 to be opened, and the refrigerant inlet switch 29 and the refrigerant pump inlet switch 31 to be closed, a compressor refrigeration circuit is formed, and the refrigerant refrigeration unit 9 is placed in the compressor mode, specifically: the outlet of the refrigerant primary side 18, the refrigerant inlet temperature sensor 108, the refrigerant inlet pressure sensor 109, the refrigerant liquid return inlet switch 20, the separation inlet 15, the gas outlet 16, the compressor inlet switch 21, the refrigerant liquid return inlet dry filter 22, the compressor 13, the compressor outlet check valve 23, the condensing inlet pressure sensor 102, the condensing inlet temperature sensor 103, the condensing mechanism 24, the condensing outlet temperature sensor 105, the condensing outlet pressure sensor 104, the condensing outlet filter 25, the condensing outlet switch 26, the refrigerant heat exchange inlet check valve 27, the throttling mechanism 28, the refrigerant heat exchange inlet pressure sensor 107, the refrigerant heat exchange inlet temperature sensor 106, the inlet of the refrigerant primary side 18.

[0054] When the refrigerant refrigeration unit 9 is placed in the compressor mode, the high-temperature and low-pressure gaseous refrigerant that is heat-exchanged at the refrigerant heat exchanger 12 flows along the pipeline through the refrigerant return liquid inlet switch 20 into the gas-liquid separation device 11 through the separation inlet 15, and the high-temperature and low-pressure gaseous refrigerant in the gas-liquid separation device 11 flows out through the gas outlet 16 at the top of the gas-liquid separation device 11 to ensure that the refrigerant entering the compressor 13 is all gaseous refrigerant. The high-temperature and low-pressure gaseous refrigerant enters the refrigerant return liquid inlet drying filter 22 through the compressor inlet switch 21 to perform drying, dehumidifying, and foreign matter removal operations on the high-temperature and low-pressure gaseous refrigerant through the refrigerant return liquid inlet drying filter 22, and the high-temperature and low-pressure gaseous refrigerant that has undergone drying, dehumidifying, and foreign matter removal operations enters the compressor 13, which, under the action of the compressor 13, changes the high-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. To prevent the high-temperature and high-pressure gaseous refrigerant from flowing back to the compressor 13 and affecting the operation of the compressor 13, a compressor outlet check valve 23 is arranged at the outlet of the compressor 13, which ensures the correctness of the refrigerant flow direction. The high-temperature and high-pressure gaseous refrigerant that has passed through the compressor outlet check valve 23 flows to the condensing mechanism 24, which performs heat release and cooling operations on the high-temperature and high-pressure gaseous refrigerant to release the heat of the high-temperature and high-pressure gaseous refrigerant to the external environment, and at the same time, the high-temperature and high-pressure gaseous refrigerant changes into low-temperature and high-pressure liquid refrigerant. The low-temperature and high-pressure liquid refrigerant enters the refrigerant outlet filter to be filtered to remove foreign matter and ensure the cleanliness of the refrigerant. The low-temperature and high-pressure liquid refrigerant flows to the refrigerant heat exchange inlet check valve 27 through the condensing outlet switch 26, which ensures the correctness of the refrigerant flow direction. The low-temperature and high-pressure liquid refrigerant that has passed through the refrigerant heat exchange inlet check valve 27 reaches the throttling mechanism 28, which converts the low-temperature and high-pressure liquid refrigerant into low-temperature and low-pressure liquid refrigerant by utilizing the throttling effect. The low-temperature and low-pressure liquid refrigerant enters the refrigerant heat exchanger 12 through the refrigerant primary side 18 inlet, and the low-temperature and low-pressure liquid refrigerant exchanges energy with the cooling liquid in the load liquid supply circulation unit 8 at the refrigerant heat exchanger 12 to cool the cooling liquid in the load liquid supply circulation unit 8 through the low-temperature and low-pressure liquid refrigerant, and then to cool the load through the cooling liquid in the load liquid supply circulation unit 8, and at the same time, the low-temperature and low-pressure liquid refrigerant changes into high-temperature and low-pressure gaseous refrigerant after exchanging energy with the cooling liquid in the load liquid supply circulation unit 8.

[0055] As Figure 6As shown, when the controller controls the compressor inlet switch 21 and the condenser outlet switch 26 to be closed, and the refrigerant inlet switch 29 and the refrigerant pump inlet switch 31 to be opened, a refrigerant pump refrigeration circuit is formed, and the refrigerant refrigeration unit 9 is placed in the refrigerant pump mode, specifically: the outlet of the refrigerant primary side 18, the refrigerant inlet temperature sensor 108, the refrigerant inlet pressure sensor 109, the refrigerant return inlet switch 20, the separation inlet 15, the gas-liquid outlet 17, the refrigerant inlet switch 29, the refrigerant pump inlet check valve 30, the condenser inlet pressure sensor 102, the condenser inlet temperature sensor 103, the condensing mechanism 24, the condenser outlet temperature sensor 105, the condenser outlet pressure sensor 104, the condenser outlet filter 25, the refrigerant pump inlet switch 31, the refrigerant pump 14, the refrigerant heat exchange inlet check valve 27, the throttling mechanism 28, the refrigerant heat exchange inlet pressure sensor 107, the refrigerant heat exchange inlet temperature sensor 106, and the inlet of the refrigerant primary side 18.

[0056] When the refrigerant refrigeration unit 9 is placed in the refrigerant pump mode, the high-temperature and low-pressure liquid refrigerant (or gas-liquid mixed refrigerant) that has been heat-exchanged at the refrigerant heat exchanger 12 flows into the gas-liquid separation device through the refrigerant inlet switch 29. The high-temperature and low-pressure liquid refrigerant (or gas-liquid mixed refrigerant) flows out of the gas-liquid separation device through the gas-liquid outlet 17, and then enters the condensing mechanism 24 through the refrigerant inlet switch 29 and the refrigerant pump inlet check valve 30 in sequence. The refrigerant pump inlet check valve 30 is used to ensure the correctness of the refrigerant flow direction and prevent the refrigerant from flowing back. The condensing mechanism 24 releases the heat carried by the high-temperature and low-pressure liquid refrigerant (or gas-liquid mixed refrigerant) to the external environment, and at the same time, the high-temperature and low-pressure liquid refrigerant (or gas-liquid mixed refrigerant) becomes low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant enters the refrigerant outlet dry filter for filtering to remove foreign matter and ensure its cleanliness. The low-temperature and low-pressure liquid refrigerant flows to the refrigerant pump 14 through the refrigerant pump inlet switch 31. Under the drive of the refrigerant pump 14, the low-temperature and low-pressure liquid refrigerant reaches the throttling mechanism 28 through the refrigerant heat exchange inlet check valve 27, and further reduces the refrigerant temperature by using the throttling effect. The low-temperature and low-pressure liquid refrigerant finally enters the inlet of the refrigerant primary side 18, and exchanges energy with the cooling liquid of the load liquid supply circulation unit 8 at the refrigerant heat exchanger 12 to cool the cooling liquid of the load liquid supply circulation unit 8, so that the cooled cooling liquid exchanges energy with the load, thereby taking away the heat of the load.

[0057] The controller of the present application controls the switch states of the compressor inlet switch 21, the condenser outlet switch 26, the refrigerant inlet switch 29, and the refrigerant pump inlet switch 31 according to the outdoor ambient temperature, so as to place the refrigerant refrigeration unit 9 in the compressor mode or the refrigerant pump mode. Not only does this reduce energy consumption and improve the energy conversion efficiency of the system, but also matches the refrigeration capacity of the cooling liquid preparation unit 2 with the heat dissipation demand of the load, improves the heat dissipation adjustment range of the heat dissipation system, meets the heat dissipation demand of the load, and avoids waste of refrigeration capacity.

[0058] In one specific embodiment, when the cooling liquid demand temperature of the load liquid supply circulating unit 8 is higher than or equal to the outdoor ambient temperature, the cooling liquid of the load liquid supply circulating unit 8 can be cooled by the natural cooling unit 10 to reduce the cooling liquid of the load liquid supply circulating unit 8 to the demand temperature.

[0059] As shown in Figure 9 , the natural cooling unit 10 comprises a natural cooling return liquid pipeline 33, a natural cooling heat exchanger 34, and a natural cooling liquid supply pipeline 35.

[0060] The natural cooling heat exchanger 34 is provided with a natural cooling primary side 36 and a natural cooling secondary side 37. One end of the natural cooling return liquid pipeline 33 is in communication with the inlet of the natural cooling secondary side 37, and the other end of the natural cooling return liquid pipeline 33 is connected to the prepared return liquid interface 4. The natural cooling return liquid pipeline 33 is provided with a heat dissipation inlet temperature sensor 56 and a heat dissipation inlet pressure sensor 57.

[0061] One end of the natural cooling liquid supply pipeline 35 is in communication with the outlet of the natural cooling secondary side 37, and the other end of the natural cooling liquid supply pipeline 35 is connected to the prepared liquid supply interface 3. The natural cooling liquid supply pipeline 35 is provided with a heat dissipation outlet temperature sensor 58 and a heat dissipation outlet pressure sensor 59.

[0062] The natural cooling primary side 36 is a heat dissipation fan 38 and / or a spray heat dissipation assembly 39, that is, the natural cooling primary side 36 is a heat dissipation fan 38, as shown in Figure 7 ; or the natural cooling primary side 36 is a spray heat dissipation assembly 39, as shown in Figure 8 ; or the natural cooling primary side 36 is a heat dissipation fan 38 and a spray heat dissipation assembly 39, as shown in Figure 9 . Preferably, the natural cooling primary side 36 of the present application is a heat dissipation fan 38 and a spray heat dissipation assembly 39, which reduces the high-temperature cooling liquid to low-temperature cooling liquid of a specified temperature through the double heat dissipation effect of the heat dissipation fan 38 and the spray heat dissipation assembly 39.

[0063] The spray cooling assembly 39 includes a spray tank 60, an electrically operated valve 61, a spray filter 62, a spray drive pump 63, a spray check valve 64, a spray flow sensor 65, and a spray disperser 66. The controller operates the spray drive pump 63 and opens the electrically operated valve 61. The spray solution in the spray tank 60 passes sequentially through the spray filter 62, spray drive pump 63, spray check valve 64, spray flow sensor 65, and spray disperser 66. Finally, under the action of the spray disperser 66, the spray solution is sprayed onto the secondary natural cooling side 37 to cool the coolant on the primary natural cooling side 36. The sprayed solution then flows back to the spray tank 60. The controller automatically adjusts the spray volume and starts / stops the spray cooling assembly 39 according to system requirements.

[0064] Furthermore, the cooling capacity of the natural cooling unit 10 is less than that of the refrigerant cooling unit 9. Therefore, users can choose either the refrigerant cooling unit 9 or the natural cooling unit 10 according to their actual needs, which not only allows for adjustment of cooling capacity but also reduces energy consumption and improves the system's energy conversion efficiency.

[0065] The modular heat dissipation system of this application includes a refrigerant cooling unit 9 and a natural cooling unit. The refrigerant cooling unit 9 includes both compressor and refrigerant pump modes. This modular heat dissipation system provides refrigerant cooling units with different cooling capacities, improving the adjustment range of the heat dissipation system's cooling capacity and covering a wider range of load heat dissipation needs. Appropriate cooling units and operating modes can be flexibly selected according to actual requirements. Furthermore, the refrigerant cooling unit 9 and the natural cooling unit are redundantly designed, improving the reliability of the liquid cooling system.

[0066] like Figure 2 and Figure 3 The diagram shows a refrigerant cooling unit 9 and a natural cooling unit 10. The refrigerant cooling unit 9 uses refrigerant as its circulating medium, which exchanges energy with the coolant in the load supply circulation unit 8 through a refrigerant heat exchanger 12. The natural cooling unit 10 uses the same coolant as the load supply circulation unit 8, flowing directly to it. Therefore, the modular heat dissipation system of this application can not only cool the coolant in the load supply circulation unit 8 through either the refrigerant cooling unit 9 or the natural cooling unit 10, but also cool the coolant in the load supply circulation unit 8 using different media, achieving physical isolation between different cooling media and adapting cooling capacity.

[0067] In one specific embodiment, the coolant temperature control circulation module 5 includes a coolant temperature control unit 40 and a load supply circulation unit 8.

[0068] like Figure 10As shown, the cooling liquid temperature control unit 40 comprises a temperature control liquid supply pipeline 41, one end of the temperature control liquid supply pipeline 41 is in communication with the inlet of the load liquid supply circulating unit 8, the other end of the temperature control liquid supply pipeline 41 is connected to the temperature control liquid supply interface 6, so that the low-temperature cooling liquid flowing out of the refrigerant secondary side 19 flows into the temperature control liquid supply pipeline 41 through the preparation liquid supply interface 3 and the temperature control liquid supply interface 6 in turn, and the low-temperature cooling liquid in the temperature control liquid supply pipeline 41 flows to the inlet of the load liquid supply circulating unit 8, so that the low-temperature cooling liquid exchanges energy with the load at the load liquid supply circulating unit 8 to take away the heat emitted by the load through the low-temperature cooling liquid, and the low-temperature cooling liquid after exchanging energy with the load becomes high-temperature cooling liquid.

[0069] The cooling liquid temperature control unit 40 further comprises a temperature control liquid return pipeline 42, one end of the temperature control liquid return pipeline 42 is in communication with the outlet of the load liquid supply circulating unit 8, the other end of the temperature control liquid return pipeline 42 is connected to the temperature control liquid return interface 7, so that the high-temperature cooling liquid after exchanging energy with the load flows to the temperature control liquid return pipeline 42 through the outlet of the load liquid supply circulating unit 8, and the high-temperature cooling liquid in the temperature control liquid return pipeline 42 flows to the inlet of the refrigerant secondary side 19 through the temperature control liquid return interface 7 and the preparation liquid return interface 4 in turn, and the energy exchange between the refrigerant and the high-temperature cooling liquid is realized at the refrigerant heat exchanger 12 to cool the high-temperature cooling liquid through the low-temperature and low-pressure refrigerant, so that the high-temperature cooling liquid becomes low-temperature cooling liquid, and the low-temperature cooling liquid is transported to the load liquid supply circulating unit 8 through the temperature control liquid supply pipeline 41 to exchange energy with the load, and the cycle is repeated to take away the heat emitted by the load.

[0070] In one specific embodiment, as shown in the figure, Figure 10 The cooling liquid temperature control unit 40 further comprises a cooling capacity distribution adjusting valve 43, a proportional adjusting branch 47 and a cooling liquid temperature control mixing tank 46, and the temperature of the cooling liquid flowing to the load liquid supply circulating unit 8 is adjusted by the cooperation of the cooling capacity distribution adjusting valve 43, the proportional adjusting branch 47 and the cooling liquid temperature control mixing tank 46.

[0071] Specifically, the cooling capacity distribution adjusting valve 43 has an adjusting inlet 44 and a first outlet 45, and the outlet of the load liquid supply circulating unit 8, the adjusting inlet 44, the first outlet 45 and the temperature control liquid return interface 7 are in communication in turn to form the temperature control liquid return pipeline 42. A heat exchange cooling flow sensor 67, a heat exchange cooling pressure sensor 68 and a heat exchange cooling temperature sensor 69 are arranged in turn between the first outlet 45 and the temperature control liquid return interface 7, the heat exchange cooling flow sensor 67 is used to collect the outlet flow of the first outlet 45, the heat exchange cooling pressure sensor 68 is used to collect the outlet pressure of the first outlet 45, and the heat exchange cooling temperature sensor 69 is used to collect the outlet temperature of the first outlet 45.

[0072] The cooling liquid temperature control mixing tank 46 has a first mixing inlet 48, and the cooling capacity distribution adjusting valve 43 also has a second outlet 49, which is connected with the first mixing inlet 48 to form a proportional adjusting branch 47, and the proportional adjusting branch 47 is sequentially provided with a branch flow sensor 70 and a branch one-way valve 50, the branch flow sensor 70 is used to collect the flow of the proportional adjusting branch 47, and the branch one-way valve 50 is used to prevent the backflow of the high-temperature cooling liquid.

[0073] The cooling liquid temperature control mixing tank 46 also has a second mixing inlet 51 and a mixing outlet 52, and the temperature control liquid supply interface 6, the second mixing inlet 51, the mixing outlet 52 and the inlet of the load liquid supply circulating unit 8 are sequentially connected to form a temperature control liquid supply pipeline 41; and the temperature control liquid supply interface 6 and the second mixing inlet 51 are sequentially provided with a heat exchange return liquid temperature sensor 71, a heat exchange return liquid pressure sensor 72 and a heat exchange return liquid one-way valve 73, the heat exchange return liquid temperature sensor 71 is used to collect the outlet temperature of the temperature control liquid supply interface 6, the heat exchange return liquid pressure sensor 72 is used to collect the outlet pressure of the temperature control liquid supply interface 6, and the branch one-way valve 50 is used to prevent the backflow of the low-temperature cooling liquid.

[0074] The cooling liquid temperature control mixing tank 46 is provided with a mixing temperature control pressure sensor 74 and a mixing temperature control temperature sensor 75, the mixing temperature control pressure sensor 74 is used to collect the pressure of the low-temperature cooling liquid in the cooling liquid temperature control mixing tank 46, and the mixing temperature control temperature sensor 75 is used to collect the temperature of the low-temperature cooling liquid in the cooling liquid temperature control mixing tank 46.

[0075] The high-temperature cooling liquid flowing out of the load liquid supply circulating unit 8 flows to the cooling capacity distribution adjusting valve 43 through the adjusting inlet 44, and the high-temperature cooling liquid is divided into two routes at the cooling capacity distribution adjusting valve 43, one route flows to the refrigerant heat exchanger 12 through the first outlet 45, and the other route flows to the cooling liquid temperature control mixing tank 46 through the proportional adjusting branch 47, and the cooling capacity distribution adjusting valve 43 is used to adjust the flow proportion of the two routes of high-temperature cooling liquid. When the temperature of the cooling liquid in the cooling liquid temperature control mixing tank 46 is relatively low, the flow of the high-temperature cooling liquid in the proportional adjusting branch 47 can be increased to increase the temperature of the cooling liquid in the cooling liquid temperature control mixing tank 46, so as to prevent the excessive supply of cooling capacity to the load; when the temperature of the cooling liquid in the cooling liquid temperature control mixing tank 46 is relatively high, the flow of the high-temperature cooling liquid in the proportional adjusting branch 47 can be reduced to reduce the temperature of the cooling liquid in the cooling liquid temperature control mixing tank 46, so as to meet the heat dissipation demand of the load. Therefore, the controller can obtain the data collected by all the temperature sensors, pressure sensors and flow sensors, so as to control the cooling capacity distribution adjusting valve 43 of the cooling liquid temperature control unit 40 according to the obtained temperature data, pressure data and flow data, so as to control the cooling liquid required by the load liquid supply circulating unit 8 to a specified temperature, so as to meet the temperature demand of the cooling liquid of the load liquid supply circulating unit 8, and realize feedback adjustment.

[0076] The coolant temperature-controlled mixing tank 46 is also equipped with a pressure regulating device 76, an automatic coolant venting device 77, a coolant distributor 78, and a coolant collector 79. The pressure regulating device 76 mainly utilizes a built-in gas pressure expansion mechanism to stabilize the system's coolant supply pressure. The automatic coolant venting device 77 is mainly used to separate and discharge gases inside the cooling system to the outside, preventing damage to the water pump and pipelines caused by gas cavitation.

[0077] In one specific implementation, such as Figure 11 As shown, the load supply circulation unit 8 includes a load supply pipeline 53, a load heat exchanger 54, and a load return pipeline 55 connected in sequence.
