[0021] Please see Figures 1 to 3 A liquid-cooled unit includes a first cabinet 10 and a second cabinet 20; the first cabinet 10 includes a first mounting cavity 101 and a second mounting cavity 102 vertically arranged; the first mounting cavity 101 is equipped with a water pump 103, a heat exchanger 104 and a heater 105; the second mounting cavity 102 is equipped with a compressor 106, a dryer filter 107, a frequency converter 108 and a water tank 109; the second cabinet 20 is provided with a third mounting cavity 201; the third mounting cavity 201 is equipped with a condenser 202.

[0022] The water tank 109, water pump 103, heat exchanger 104 and heater 105 are connected in sequence to form a coolant circulation loop; the coolant circulation loop also includes a first connecting pipe 110 connected to the output end of the heater 105 and external electronic equipment, and a second connecting pipe 111 connected to the water tank 109 and external electronic equipment.

[0023] The heat exchanger 104, compressor 106, dryer filter 107, frequency converter 108 and condenser 202 are connected in sequence to form a cooling medium circulation loop.

[0024] Specifically, in this embodiment, the coolant circulation loop is connected to external electronic equipment through a first pipe and a second pipe. The coolant in the loop regulates the temperature of the external electronic equipment. The electronic equipment may include heat-generating devices such as air conditioners, battery cabinets, and machinery; in this embodiment, it is a battery module. The coolant is antifreeze, and can be an aqueous solution of ethanol, ethylene glycol, or glycerol as the mother liquor. The water tank 109 is used to replenish the coolant circulation loop, and the water pump 103 is used to realize the power circulation of the coolant in the coolant circulation loop. The heat exchanger 104 is used to realize the heat exchange between the coolant in the coolant circulation loop and the cooling medium in the cooling medium circulation loop. The cooling medium in the cooling medium circulation loop is Freon, etc. Specifically, the heat exchanger 104 is a plate heat exchanger 104, and the heater 105 is a PCT heater 105.

[0025] Furthermore, in this embodiment, the liquid cooling unit involved in this utility model includes the following three operating modes:

[0026] Cooling Mode: Utilizing the principle of compression refrigeration, coolant cooling is achieved through heat exchanger 104. Water pump 103 drives coolant circulation to cool the battery, effectively addressing issues such as excessive temperature rise caused by high-temperature environments or charging / discharging. When the ambient temperature is high and the battery releases a large amount of heat, compressor 106 can start / stop in stages and adjust its output power according to temperature control conditions, ensuring the temperature of the cooling medium is always maintained within a suitable range. Heating Mode: When the ambient temperature is too low, the battery's charging / discharging efficiency decreases. In this case, if the user detects that the temperature is too low, they can control the liquid cooling unit to start the heating mode, heating the cooling medium through heater 105.

[0027] Self-circulation mode: The compressor 106 does not start, and the water pump 103 drives the coolant circulation to meet the battery cooling under low heat load conditions.

[0028] The liquid cooling unit involved in this utility model has a compact structure due to the arrangement of the first cabinet 10 and the second cabinet 20; and it can efficiently adjust the temperature of external electronic equipment as needed by setting up a coolant circulation loop and a cooling medium circulation loop, thereby improving the user experience.

[0029] In one specific embodiment, there are two compressors 106 and two condensers 202; one end of each compressor 106 is connected to a heat exchanger 104, and the other end is connected to the two condensers 202.

[0030] In this embodiment, the arrangement of two compressors 106 and two condensers 202 greatly improves cooling efficiency, making it suitable for industrial applications. Furthermore, two condensers 202 are arranged side-by-side in the third mounting cavity 201, and a fan 203 is mounted on them. The two compressors 106 are arranged side-by-side in the second mounting cavity 102.

[0031] In one specific embodiment, three heaters are arranged side by side, and the two ends of each heater are connected by a connecting pipe 112; one connecting pipe 112 is connected to the first connecting pipe 110, and the other connecting pipe 112 is connected to the heat exchanger 104. In this embodiment, the arrangement of three heaters 105 can effectively improve the heating efficiency of the coolant.

[0032] In one specific embodiment, temperature sensors for temperature detection are installed inside the first connecting pipe 110 and the second connecting pipe 111. In this embodiment, the temperature sensors effectively monitor the temperature of the coolant in the coolant circulation loop, thereby enabling effective temperature control of external electronic equipment.

[0033] In one specific embodiment, a liquid level sensor is installed inside the water tank 109. In this embodiment, the liquid level sensor can effectively monitor the coolant storage status inside the water tank 109, thereby replenishing the coolant in the water tank 109. Furthermore, the water tank 109 is equipped with a filling valve and an venting valve. The filling valve can replenish the coolant in the water tank 109, and the venting valve can effectively expel excess gas from the water tank 109, thereby ensuring the pressure balance of the water tank 109.

[0034] In one specific embodiment, the pump 103 is connected to a hand valve and a check valve at both ends.

[0035] In one specific embodiment, an electronic expansion valve is provided between the dryer filter 107 and the heat exchanger 104.

[0036] The liquid cooling unit involved in this utility model has a compact structure due to the arrangement of the first cabinet 10 and the second cabinet 20; and it can efficiently adjust the temperature of external electronic equipment as needed by setting up a coolant circulation loop and a cooling medium circulation loop, thereby improving the user experience.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
