The fan 410 drives the air flow to dissipate heat from the heat exchanger 400, thereby improving the heat exchange efficiency of the heat exchanger 400.

[0030] In some embodiments, as shown in Figures 2 to 4As shown, the heat exchanger 400 is provided as a plate heat exchanger, including a liquid inlet and a liquid outlet, and a plurality of liquid flow channels are arranged in the heat exchanger 400 to communicate the liquid inlet and the liquid outlet. Specifically, the heat exchanger 400 is provided as a micro-channel plate heat exchanger, and a plurality of liquid flow channels for the cooling liquid to flow through are arranged in the heat exchanger 400. The plurality of liquid flow channels with small cross-sectional areas are arranged to increase the contact area between the cooling liquid and the heat exchanger 400, thereby increasing the heat exchange efficiency of the heat exchanger 400 and improving the heat dissipation effect.

[0031] In some embodiments, as shown in Figure 1 As shown, the air outlet is further provided with a filter screen 420. The filter screen 420 is used to filter dust and reduce dust pollution.

[0032] In some embodiments, as shown in Figure 1 As shown, the shell 100 includes a base 130, a middle shell 120, and an upper cover 110.

By arranging the shell 100 as the detachably connected base 130, middle shell 120, and upper cover 110, the shell 100 is convenient to disassemble and maintain. By arranging the mounting bracket 140 on the base 130 to install the liquid pool 200, the heat exchanger 400, and the air cooling device in different regions, the components in the liquid cooling cabinet are more reasonably distributed, and the heat dissipation effect is better. Specifically, the base 130 and the middle shell 120 are connected by buckles and / or threads. The middle shell 120 and the upper cover 110 are connected by a hinge to enable the upper cover 110 to be flipped open to one side. The mounting bracket 140 is formed by welding hollow steel materials to ensure that the mounting bracket 140 can bear the components and separate the components. In some embodiments, the bottom of the base 130 is further provided with moving wheels to make the liquid cooling cabinet convenient to move.

[0033] In some embodiments, as shown in Figure 1 As shown, the upper cover 110 is hinged to the middle shell 120, and a gas strut 150 is arranged between the upper cover 110 and the middle shell 120 to support the upper cover 110. The hinge between the upper cover 110 and the middle shell 120 enables the upper cover 110 to be flipped open to one side.

[0034] In some embodiments, asFigure 2 As shown, the base 130 comprises a bottom plate, and an air inlet 131 is arranged on the bottom plate. The air inlet 131, the air outlet, and the fan 410 cooperate to form an air flow channel passing through the surface of the heat exchanger 400 in the shell 100. Under the driving of the fan 410, room temperature air enters the liquid cooling cabinet from the air inlet 131 and flows through the surface of the heat exchanger 400 to cool the heat exchanger 400, and then high-temperature gas is discharged from the air outlet to the outside of the shell 100. The heat exchanger 400 is cooled by air cooling, which improves the heat dissipation efficiency of the liquid cooling cabinet.

[0035] In some embodiments, as shown in Figures 2 to 4 As shown, the liquid cooling cabinet is also provided with a control device 500, and the control device 500 is electrically connected to the fan 410 and the liquid pump 300 and is used to control the working of the fan 410 and the liquid pump 300. Specifically, the control device 500 is a control box, and a power module and a control module are arranged in the control box. The power module and the control module are electrically connected to the fan 410 and the liquid pump 300 to control the working state of the fan 410 and the liquid pump 300. In addition, the power module and the control module can also be electrically connected to other elements such as sensors to detect the internal state of the liquid cooling cabinet.

[0036] In some embodiments, as shown in Figure 1 As shown, the shell 100 is also provided with a man-machine interaction device 600, and the man-machine interaction device 600 is electrically connected to the control device 500. Specifically, the man-machine interaction device 600 can be a display screen or a touch screen with keys.

[0037] In some embodiments, as shown in Figure 4 As shown, the liquid injection pipe 220 is arranged between the liquid injection port of the liquid pool 200 and the liquid pump 300, and the liquid discharge pipe 210 is arranged between the liquid discharge port of the liquid pool 200 and the heat exchanger 400. Control valves are arranged on the liquid injection pipe 220 and the liquid discharge pipe 210. By arranging the control valves on the liquid injection pipe 220 and the liquid discharge pipe 210, the circulation flow rate of the cooling liquid can be controlled. By controlling the output power of the liquid pump 300, the circulation flow rate of the cooling liquid can be controlled. By controlling the flow rate and flow rate of the cooling liquid, the cooling efficiency of the liquid cooling cabinet to the cooling device in the liquid pool 200 can be controlled, so that the cooling efficiency of the liquid cooling cabinet matches the demand of the cooling device, and the system energy consumption of the liquid cooling cabinet is reduced.

[0038] In some embodiments, such as Figure 4 As shown, the liquid inlet of the liquid pool 200 is located at the upper end of the side wall of the liquid pool 200, and the liquid outlet of the liquid pool 200 is located at the bottom of the liquid pool 200. That is, low-temperature coolant is injected into the liquid pool 200 from the upper end of the liquid pool 200, and high-temperature coolant is discharged from the bottom of the liquid pool 200. The height difference is used to make the coolant flow from top to bottom over the surface of the device to be cooled, so as to achieve the cooling of the device.

[0039] In summary, the immersion liquid cooling cabinet of this embodiment has the advantages of high heat dissipation efficiency, low system energy consumption, reasonable space distribution, and high reliability. Moreover, it adopts an integrated design, occupies little space, and is easy to move, making it especially suitable for small-sized equipment to be cooled.
