Detailed Embodiments

[0020] The technical solution of the present utility model will be further described below through embodiments:

[0021] The present utility model provides a liquid cooling unit for testing, in combination with Figures 1-2 As shown, the liquid cooling unit includes: a chassis 100 and a liquid cooling component, and the liquid cooling component is located inside the chassis 100. When using the liquid cooling unit to test the liquid cooling plate, the chassis 100 is moved to the position of the cabinet, and the channels of the liquid cooling component are connected to those of the liquid cooling plate. By utilizing the refrigeration and heating functions of the liquid cooling component, the uniform temperature test of the liquid cooling plate under refrigeration and heating conditions is cooperatively achieved.

[0022] Specifically, please continue to refer to Figure 1 As shown, the chassis 100 is provided with a chassis cover 101, four matrix-distributed universal wheels 102 and a handle 103. The chassis cover 101 covers an opening on the top wall of the chassis 100, all four universal wheels 102 are located on the bottom wall of the chassis 100, and the handle 103 is located on the top wall of the chassis 100.

[0023] When using this liquid cooling unit, the user can replenish the liquid cooling component after opening the chassis cover 101, and a funnel can be used to assist in the liquid replenishment operation; the user can move the chassis 100 by pulling the handle 103 so that the chassis 100 rolls on the casters 102.

[0024] It is worth mentioning that although in this embodiment, the chassis cover 101 and the handle 103 are provided on the top wall of the chassis 100, in other embodiments, the chassis cover 101 and the handle 103 can also be provided on the side wall of the chassis 100.

[0025] Specifically, as shown in Figures 2-3 This liquid cooling component includes: a water system component 200, a refrigerant system component 300, and a heat exchanger 400; the water system component 200 includes: a liquid inlet interface 201, a liquid outlet interface 202, a water tank 203, a water pump 204, a heater 205, and two ball valves 206. The liquid inlet interface 201, the water tank 203, the water pump 204, the heat exchanger 400, the heater 205, and the liquid outlet interface 202 are connected in sequence. Ball valves 206 are provided between the liquid inlet interface 201 and the water tank 203, and between the heater 205 and the liquid outlet interface 202; the refrigerant system component 300 includes: a compressor 301, a radiator 302, an expansion valve 303, a pressure switch 304, a fan 305, and two needle valves 306. The compressor 301, the radiator 302, the expansion valve 303, and the heat exchanger 400 are connected in sequence and form a loop. A pressure switch 304 is provided between the compressor 301 and the radiator 302. The fan 305 is arranged facing the radiator 302. Needle valves 306 are provided between the heat exchanger 400 and the compressor 301, and between the radiator 302 and the expansion valve 303.

[0026] When the liquid cooling component is refrigerating, open the two ball valves 206 and the two needle valves 306. The refrigerant (usually fluorine) in the loop of the refrigerant system component 300 forms a high-temperature and high-pressure gas after passing through the compressor 301. The pressure switch 304 monitors the pressure of the refrigerant. The refrigerant forms a low-temperature and high-pressure liquid after passing through the radiator 302. The fan 305 extracts the heat dissipated by the radiator 302. The refrigerant forms a low-temperature and low-pressure fog-like gas after passing through the expansion valve 303. The water pump 204 of the water system component 200 extracts the coolant from the water tank 203 and conveys it to the heat exchanger 400. The refrigerant of the refrigerant system component 300 exchanges heat with the coolant of the water system component 200 at the heat exchanger 400. After the heat exchange, the refrigerant in the loop of the refrigerant system component 300 returns to the compressor 301 again. The coolant of the water system component 200 flows into the liquid cooling plate to be tested through the liquid outlet interface 202, and the coolant in the liquid cooling plate returns to the water tank 203 through the liquid inlet interface 201, and circulates in this way.

[0027] When the liquid cooling component is heating, the refrigerant system component 300 does not work. The water pump 204 of the water system component 200 pumps out the coolant from the water tank 203, and after passing through the heat exchanger 400, it is transmitted to the heater 205. The coolant is heated by the heater 205 and then flows into the liquid cooling plate to be tested through the liquid outlet interface 202. The coolant in the liquid cooling plate then returns to the water tank 203 through the liquid inlet interface 201, and this cycle repeats.

[0028] It is worth mentioning that the water system component 200 also has the function of storing coolant. Specifically, when the liquid cooling component is not working, the ball valve 206 at the liquid outlet interface 202 can be closed first, and the water pump 204 is used to pump the coolant in the liquid cooling plate to be tested into the water tank 203 until the water tank 203 is filled, and finally the ball valve 206 at the liquid inlet interface 201 is closed.

[0029] In this embodiment, the heat exchanger 400 is a plate heat exchanger; the expansion valve 303 is an electronic expansion valve. Of course, in other embodiments, the heat exchanger 400 can also adopt other types of heat exchangers, and the expansion valve 303 can also adopt other types of expansion valves, as long as the refrigeration and heating functions of the liquid cooling component can be satisfied.

[0030] More specifically, the liquid cooling component further includes: an electrical system component 500. The expansion valve 303, the pressure switch 304, and the fan 305 are all electrically connected to the electrical system component 500. When the refrigerant system component 300 is working, the electrical system component 500 can be used to control the expansion valve 303, the pressure switch 304, and the fan 305. The control principle of the electrical system component 500 is the same as that of the electrical system component of the existing liquid cooling unit, and will not be elaborated here.

[0031] More specifically, the water tank 203 is provided with a liquid filling cover 2031, a liquid level gauge 2032, and a liquid level sensor 2033. The liquid filling cover 2031 covers a liquid filling port on the top wall of the water tank 203, and the liquid filling cover 2031 is directly opposite to the chassis cover 101 in the up and down direction. The liquid level gauge 2032 is located inside the water tank 203, and the liquid level sensor 2033 passes through the top wall of the water tank 203. Both the liquid level gauge 2032 and the liquid level sensor 2033 are electrically connected to the electrical system component 500.

[0032] During use, the user can open the liquid filling cover 2031 and then fill the water tank 203; the liquid level gauge 2032 is used to monitor the liquid volume inside the water tank 203; the liquid level sensor 2033 is used to monitor whether the liquid volume inside the water tank 203 exceeds the upper limit.

[0033] It is worth mentioning that although in this embodiment, the liquid filling cover 2031 is provided on the top wall of the water tank 203, in other embodiments, the liquid filling cover 2031 can also be provided on the side wall of the water tank 203.

[0034] More specifically, the liquid cooling assembly further includes: four pressure sensors 600, five temperature sensors 700, and two filters 800. Pressure sensors 600 are provided between the liquid inlet interface 201 and the water tank 203, between the heater 205 and the liquid outlet interface 202, between the heat exchanger 400 and the compressor 301, and between the radiator 302 and the expansion valve 303; temperature sensors 700 are provided between the liquid inlet interface 201 and the water tank 203, between the heater 205 and the liquid outlet interface 202, between the heat exchanger 400 and the compressor 301, between the compressor 301 and the radiator 302, and between the radiator 302 and the expansion valve 303; filters 800 are provided between the water tank 203 and the water pump 204, and between the radiator 302 and the expansion valve 303; the four pressure sensors 600 and the five temperature sensors 700 are both electrically connected to the electrical system assembly 500.

[0035] During use, the pressure sensor 600 is used to monitor the pressure value in the pipeline; the temperature sensor 700 is used to monitor the temperature value in the pipeline; the two filters 800 are respectively used to filter the refrigerant of the refrigerant system assembly 300 and the coolant of the water system assembly 200.
