Detailed Description of the Preferred Embodiments

[0027] The present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0028] The technical solution of the present utility model provides a cabinet-type air-liquid cooling capacity distribution unit.

[0029] Referring to Figures 1 to 3 , in this embodiment, it includes:

[0030] Cabinet;

[0031] A heat exchange module disposed in the cabinet, the heat exchange module includes a housing 11, a heat exchanger 12, a power supply device 13, a fan assembly 14 and a control assembly 15. The heat exchanger 12 is disposed above the control assembly 15, and the heat exchanger 12 is used for heat exchange with a liquid cooling medium; the power supply device 13 is disposed above the inner wall of the housing 11, and the power supply device 13 is electrically connected to the fan assembly 14. The fan assembly 14 is disposed opposite to the heat exchanger 12, and the fan assembly 14 is used for extracting cold air for heat dissipation;

[0032] A heat load 2 connected to the heat exchange module, and the heat load 2 is connected to the heat exchange module through a pipeline, and a liquid cooling medium flows in the pipeline;

[0033] A filtering module connected to the pipeline, and the filtering module is used for purifying the liquid cooling medium;

[0034] A driving pump 16 disposed at the bottom end of the cabinet, and the driving pump 16 is communicated with the pipeline to drive the liquid cooling medium to circulate in the pipeline.

[0035] Optionally, in this embodiment, the cabinet-type air-liquid cooling capacity distribution unit includes a cabinet body, a heat exchange module, a heat load 2, a filtration module, and a driving pump 16. The heat exchange module, the heat load 2, the filtration module, and the driving pump 16 are all arranged in the cabinet body. The heat exchange module includes a housing 11, a heat exchanger 12, a power supply device 13, a fan assembly 14, and a control assembly 15. The heat exchanger 12 is arranged above the control assembly 15. The heat exchanger 12 is used for heat exchange with a liquid cooling medium. The power supply device 13 is arranged above the inner wall of the housing 11, and the power supply device 13 is electrically connected to the fan assembly 14, that is, the power supply device 13 is used to supply power to the fan assembly 14. When the heat exchanger 12 exchanges heat with the liquid cooling medium, the temperature of the heat exchanger 12 rises, and the temperature of the liquid cooling medium drops. The fan assembly 14 operates, and the fan assembly 14 draws cold air into the housing 11. That is, after the cold air enters the housing 11, it exchanges heat with the heat exchanger 12 to complete the cooling of the heat exchanger 12. After the cold air absorbs the heat of the heat exchanger 12, it becomes hot air and is discharged to the external environment, realizing the heat exchange between the liquid cooling medium and the heat exchanger 12. The heat exchanger 12, the power supply device 13, the fan assembly 14, and the control assembly 15 are all electrically connected to the control assembly 15. The heat load 2 is connected to the heat exchange module. The heat load 2 and the heat exchange module are connected through a pipeline, and a liquid cooling medium flows in the pipeline. That is, when the liquid cooling medium flows through the heat load 2 through the pipeline, the liquid cooling medium exchanges heat with the heat load 2, and the heat load 2 is cooled. The temperature of the liquid cooling medium rises. The liquid cooling medium continues to flow through the heat exchange module through the pipeline. The heat exchanger 12 exchanges heat with the liquid cooling medium, causing the temperature of the liquid cooling medium to drop, and flows back to the heat load 2 along the pipeline to circulate heat exchange with the heat load 2. At the same time, the temperature of the heat exchanger 12 rises, and the control assembly 15 controls the fan assembly 14 to work. The fan assembly 14 located on the housing 11 operates, drawing cold air into the housing 11 to dissipate heat with the heat exchanger 12, thereby reducing the temperature of the liquid cooling medium. The exchanged hot air is discharged outdoors. The filtration module is used to purify the liquid cooling medium, and the driving pump 16 drives the liquid cooling medium to circulate in the pipeline. Through the setting of the above modules and components, by using the method of air-assisted liquid cooling medium, the cyclic heat dissipation of the heating element is realized, enabling the chip and electronic components to be at a suitable working temperature and reducing the risk of electronic component failure due to excessive temperature.

[0036] In this embodiment, the filtering module includes a filter 31 and an exhaust valve 32. The filter 31 can effectively remove solid particles and impurities in the liquid cooling medium, ensuring the purity of the cooling medium, maintaining the stable operation of the CDU system and improving its working efficiency. The exhaust valve 32 is connected to the heat exchange module. During the operation of the air-liquid cabinet type cooling capacity distribution unit, due to the circulation of the fluid and the change of temperature, a certain amount of gas may be generated or mixed in the system. These gases will affect the fluidity and heat transfer efficiency of the fluid, and may even lead to a decline in system performance or failure. The main function of the exhaust valve 32 is to timely remove these gases, keeping the fluid inside the system pure and smooth. At the same time, when the gas accumulates to a certain extent in the system, it may form a gas resistance or gas lock phenomenon, hindering the normal flow of the fluid. The regular or automatic exhaust function of the exhaust valve 32 can effectively prevent this situation from occurring, ensuring that the system is always in the best operation state.

[0037] In this embodiment, a temperature sensor 33 and a pressure transmitter 34 are provided between the liquid inlet of the heat load 2 and the filter 31. The temperature sensor 33 is used to monitor the temperature change in the system, and the pressure transmitter 34 is used to monitor the pressure change in the system, ensuring that the system operates within a safe range. Both the temperature sensor 33 and the pressure transmitter 34 are electrically connected to the control component 15, that is, the temperature sensor 33 and the pressure transmitter 34 can real-time feedback the temperature and pressure information in the system. When a certain value exceeds the set value, the control component 15 can close the valve or adjust the operating speed of the drive pump 16, thereby avoiding the occurrence of safety accidents. Further, a pressure transmitter 34, a temperature sensor 33 and a flow transmitter 35 are provided between the liquid outlet of the heat load 2 and the heat exchange module. The flow transmitter 35 is used to monitor the flow change in the system.

[0038] In this embodiment, a drain valve 36 is further connected to the output end of the heat exchange module. The drain valve 36 is used for liquid replacement and draining of the system during maintenance. Further, a check valve 37 is provided on the pipeline of the filter 31 to prevent the reverse flow of the liquid cooling medium, which helps to reduce the energy loss in the system and improve the operating efficiency of the entire air-liquid cabinet type cooling capacity distribution unit.

[0039] In this embodiment, multiple groups of heat exchangers 12 and multiple groups of fan assemblies 14 are provided inside the housing 11, and multiple groups of sockets are provided on the housing 11. Both the fan assemblies 14 and the heat exchangers 12 are detachably connected to the inside of the housing 11 through the sockets. The number of groups of the fan assemblies 14 and the heat exchangers 12 is adjusted according to the power and number of the heating elements. That is, when the amount of heat to be exchanged is large, the number of groups of the fan assemblies 14 and the heat exchangers 12 can be increased for adjustment. Further, when the heat exchanger 12 is set as one group, it can be horizontally or inclinedly arranged inside the housing 11. When the heat exchanger 12 is set as two groups, it can be set in a V shape, which is not limited here.

[0040] In this embodiment, an expansion tank 38 is further provided on the pipeline. The expansion tank 38 is connected to the input end of the heat exchange module. Due to the temperature change of the liquid cooling medium, its volume will also change accordingly. The expansion tank 38 absorbs the expansion amount generated by this temperature change, preventing the system from being damaged due to a sharp change in pressure.
