[0018] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0019] To address the problems mentioned in the background art, this utility model provides a more compact rack-mounted air-liquid cooling device for scenarios where server space is limited, such as... Figure 1 The device includes a rack-mount enclosure 1. A first fan unit 6 and a second fan unit 7 are located at the rear end of the rack-mount enclosure 1. The first fan unit 6 and the second fan unit 7 are arranged vertically and alternately to accommodate limited height space, and each is equipped with a fan 10 (model EC-20572-22BU1-026). The second fan unit 7 is connected to the rack-mount enclosure 1 via a fan mounting plate 71, while the first fan unit 6 is directly connected to the rack-mount enclosure 1. An air guide bracket 8 is installed between the first fan unit 6 and the second fan unit 7, physically separating the upper and lower fan airflow channels and guiding the airflow evenly through the fins of the condenser 3. The condenser 3 is installed at the front end of the rack-mount enclosure 1. The condenser 3 is L-shaped and its outer surface is attached to the inner wall of the rack-mount enclosure 1. The condenser 3 serves as the core heat exchange unit, where the high-temperature coolant from the server exchanges heat with the airflow from the fan 10, achieving liquid-to-gas heat dissipation. The condenser inlet 31 connects to the return liquid line 2, and the condenser outlet 32 ​​connects to the supply liquid line 4. The return liquid line 2, supply liquid line 4, water replenishment circuit 9, and electrical control box 5 are arranged in the space between the fan mounting bracket and the condenser 3. The electrical control box 5 is equipped with an independent cover. The return liquid line 2 includes a return liquid port 21, an expansion tank 23, and a water pump 24 connected in sequence. A first pressure sensor 22 and a first temperature sensor 29 are installed between the return liquid port 21 and the expansion tank 23. The water pump 24 is connected to the condenser 3 through a one-way valve 25, and a second pressure sensor 26 is installed at the front end of the condenser 3 inlet. The electrical control box is located above the expansion tank 23 and connected to the inner wall of the rack-type housing 1.

[0020] The water replenishment circuit 9 includes an injection port 91, a water replenishment tank 92, and a water replenishment pump 93; the water replenishment tank 92 is connected to the expansion tank 23 via a one-way valve 94. When the water replenishment circuit 9 and the expansion tank 23 are at low liquid levels, the water replenishment pump 93 is activated to replenish the expansion tank 23. The liquid supply pipeline 4 includes a liquid supply port 41 and a Y-type filter 42; a second temperature sensor 43 and a third pressure sensor 44 are installed between the Y-type filter 42 and the liquid supply port 41.

[0021] The condenser inlet 31 is connected to the water pump 24, and the condenser outlet 32 ​​is connected to the liquid supply line 4. The Y-type filter 42 in the liquid supply line 4 is responsible for intercepting impurities and filtering particulate matter from the coolant. The second pressure sensor 26 and the third pressure sensor 44 are used to check the pressure value, and the pressure difference between the two sensors determines whether the Y-type filter 42 is clogged. The condenser 3 also includes a condenser exhaust port 33 and a condenser drain port 34, with the condenser exhaust port 33 positioned higher than the condenser drain port 34.

[0022] like Figure 1 As shown, the condenser exhaust port 33, condenser liquid drain port 34, liquid return port 21, liquid supply port 41, liquid injection port 91, power socket 13, and network port 14 are all centrally located at the rear end of the rack-mounted housing 1. The liquid return port 21 and liquid supply port 41 adopt a chuck-type quick-connect structure, and the liquid drain port and exhaust port adopt a needle valve leak-proof design. Figure 5 As shown, the water tank drain pipe 27 and the water tank vent pipe 28 are located on the front panel 11 of the tank body. Figure 4 The front panel 11 of the enclosure shown is also equipped with a touch screen 15, which makes it convenient for staff to operate the equipment.

[0023] The embodiment of this utility model is as follows: The frame-type housing 1 has dimensions of 444×445×1050mm. The front panel 11 of the housing is equipped with a touch screen 15, a network port 14, a power socket 13, a condenser exhaust port 33, a condenser drain port 34, a return port 21, a supply port 41, and an injection port 91. The cooling circuit includes a return pipe 2 and a supply pipe 4. The return pipe 2 is sequentially connected to the return port 21, the expansion tank 23, the water pump 24, and the one-way valve 25 to the condenser inlet 31; as shown... Figure 3As shown, there are two parallel water pumps 24, each with a check valve 25 at its outlet. The liquid supply pipeline 4 runs from the condenser outlet 32 ​​through the Y-type filter 42 to the liquid supply port 41. The air-cooled unit is located at the rear of the equipment, with the front panel 11 of the housing serving as the air inlet cover. The air entering from the front of the equipment passes through the condenser 3 and is then separated by the air guide bracket 8, which effectively guides the airflow. Finally, the air is discharged by the fan 10. The first fan group 6 and the second fan group 7 each have two fans 10 installed. The liquid flow direction of the water replenishment circuit 9 is: injection port 91, water replenishment tank 92, water replenishment pump 93, check valve 24 to expansion tank 23. The water replenishment circuit 9 injects liquid into the water replenishment tank 92 through the injection port 91. The water replenishment tank 92 is equipped with a water level switch sensor for low liquid level alarm. Then, the liquid flows through the water replenishment pump 93 and the check valve 24 to the expansion tank 23.

[0024] Cooling water enters the condenser 3 via the return pipe 2. Specifically, the cooling water enters the expansion tank 23 through the return port 21, then passes through the water pump 24 and the one-way valve 25 before entering the condenser 3 for cooling. After cooling, the water is discharged from the condenser 3 through the supply pipe 4. There are two water pumps 24 connected in parallel. Both water pumps 24 can be started simultaneously or one can be started at a time. The Y-type filter 42 has a second pressure sensor 26 and a third pressure sensor 44 at its front and rear ends to monitor the pressure values. The pressure difference is used to determine whether the Y-type filter 42 is clogged.

[0025] This utility model's equipment boasts a heat dissipation capacity of up to 16kW, with a compact cabinet size of only 444×445×1050mm. The return port 21, supply port 41, drain port, vent port, replenishment port, mesh port, and power socket are all located at the front and rear of the cabinet, facilitating modular installation and operation. The return port 21 and supply port 41 utilize a chuck design for quick and efficient pipe connection. The vent ports of the condenser 3 and expansion tank 23 employ needle valves to effectively prevent leakage. The entire unit's exterior fasteners are countersunk screws, which are aesthetically pleasing and effectively prevent collisions between the device and the frame. The compact internal space effectively saves space, allowing for a more streamlined design that maximizes space utilization while maintaining product functionality and efficiency. This utility model has a 16kW heat dissipation capacity, yet all structures are integrated within a 0.2m... 3 Within its volume, it boasts a space efficiency far exceeding that of traditional equipment, with a high heat dissipation density; the interfaces are centrally and modularly arranged at both ends for convenient maintenance; the fans are installed in a vertically staggered stacking manner, saving space while ensuring air-cooling efficiency; the condenser is designed in an L-shape to increase the cooling area while saving space, freeing up more space for other circuits.

[0026] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
