Description

Technical Field

[0001] The utility model belongs to the technical field of data center refrigeration, and in particular relates to an immersion liquid cooling cabinet. Background Art

[0002] In current data center cooling technology, immersion liquid cooling has been widely adopted in cabinets to efficiently dissipate heat from heat-loaded equipment such as servers. However, existing technologies largely focus on optimizing server installation, layout, and cabling paths, while neglecting the cooling needs of switches, an equally important communications device within the data center. As an indispensable and critical component in data centers, the stable operation of switches is crucial to ensuring efficient and reliable data transmission.

[0003] Currently, most immersion-type liquid-cooled air conditioning cabinets have a large sealed box (tank). Inside the tank are arranged liquid inlet and outlet pipes, server mounting points, and other functions. All servers or heat-generating electronic components are also placed within this large tank. Current liquid-cooled cabinet technology has disadvantages such as difficulty in processing, manufacturing, and leak detection, as well as high manufacturing costs. Furthermore, in actual use, a large amount of coolant must be filled regardless of whether the tank is fully populated with servers. This large amount of coolant leads to high costs for immersion-type liquid cooling, making it unfavorable for pilot applications of immersion-type liquid cooling cabinets. Furthermore, large tanks also have disadvantages such as low internal coolant flow rate, difficulty in flow field control, and slow cooling response to local hot spots. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an immersion liquid cooling cabinet which can increase the flow rate of the cooling liquid and make the flow field more uniform.

[0005] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0006] An immersion liquid cooling cabinet, comprising:

[0007] The housing is provided with a mounting cavity and a liquid inlet manifold and a liquid outlet manifold for conveying the coolant;

[0008] At least one liquid storage box is installed in the installation cavity, and a sealed cavity for installing a heating device is provided in the liquid storage box; the sealed cavity is connected to the liquid inlet manifold and the liquid outlet manifold;

[0009] A flow channel is installed in the sealed cavity, and the flow channel is communicated with the liquid inlet manifold and the liquid outlet manifold.

[0010] Furthermore, the installation position of the flow channel corresponds to the heating device, and the flow channel is closer to the heating device, which significantly improves the heat dissipation efficiency.

[0011] Furthermore, the flow channel is provided with a liquid inlet and at least one liquid outlet, the liquid inlet is connected to the liquid inlet manifold; the liquid outlet corresponds to the heating element, and the flow channel guides the coolant with higher cooling capacity to the heating element, thereby significantly improving the heat dissipation efficiency.

[0012] Furthermore, the liquid storage box is provided with a first liquid inlet joint for communicating with the liquid inlet manifold, and a first liquid outlet joint for communicating with the liquid outlet manifold.

[0013] Furthermore, the first liquid inlet connector and the first liquid outlet connector are one-way quick-plug connectors, which can realize blind plug connection between the liquid inlet manifold and the liquid outlet manifold.

[0014] Furthermore, the liquid inlet manifold is arranged at the bottom of the installation cavity and is detachably connected to the first liquid inlet joint; the liquid outlet manifold is arranged at the top of the installation cavity and is detachably connected to the first liquid outlet joint. The coolant enters from the bottom and exits from the top, and can fully exchange heat with the heating device.

[0015] Furthermore, a fixing structure for fixing the heating element is provided on the inner side wall of the top of the liquid storage box.

[0016] Furthermore, an installation structure for installing the liquid storage box into the installation cavity is provided on the outer side wall of the top of the liquid storage box.

[0017] Furthermore, a hoisting hole for hoisting is provided on the outer side wall of the top of the liquid storage box, which makes it easy to take the liquid storage box.

[0018] Furthermore, a liquid level sensor and a temperature sensor are installed on the top of the sealed cavity to facilitate regulating the flow of the coolant.

[0019] Beneficial effects of the utility model:

[0020] This immersion-type liquid-cooling cabinet utilizes a common, non-sealed mounting cavity, coupled with multiple small liquid-holding boxes. Compared to a single, large mounting cavity, the smaller liquid-holding boxes increase the coolant flow rate and achieve a more uniform flow field. The liquid-holding boxes are arranged with flow channels, whose specific shape and position correspond to the heat-generating components, improving heat dissipation efficiency. Furthermore, the smaller liquid-holding boxes reduce the difficulty of manufacturing and leak detection. Coolant can also be filled based on the number of heat-generating components, significantly improving coolant utilization and reducing costs. This immersion-type liquid-cooling cabinet addresses the technical shortcomings of most current immersion-type liquid-cooling cabinets. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Please refer to Figure 1 and Figure 2 , which is a preferred embodiment of the present invention, the immersion liquid cooling cabinet includes: a shell 100, which is provided with an installation cavity 110 and a liquid inlet manifold 140 and a liquid outlet manifold 150 for conveying cooling liquid; at least one liquid storage box 200, which is installed in the installation cavity 110, and the liquid storage box 200 is provided with a sealed cavity 210 for installing a heating device 300 (such as a server); the sealed cavity 210 is connected to the liquid inlet manifold 140 and the liquid outlet manifold 150; a flow channel 250 is installed in the sealed cavity 210, and the flow channel 250 is connected to the liquid inlet manifold 140 and the liquid outlet manifold 150.

[0038] The immersion liquid cooling cabinet uses a common, non-sealed installation cavity 110, combined with a plurality of small liquid storage boxes 200. Compared with a large installation cavity 110, the small liquid storage boxes 200 can increase the flow rate of the coolant and make the flow field more uniform. The liquid storage boxes 200 are internally arranged with flow channels 250, and the specific shape and position of the flow channels 250 can correspond to the heating components 300, thereby improving the heat dissipation efficiency. Furthermore, the small liquid storage boxes 200 can reduce the difficulty of manufacturing and leak detection. The coolant can also be filled according to the number of heating components 300, which greatly improves the utilization rate of the coolant and reduces the cost. The immersion liquid cooling air conditioner in this article effectively solves the technical deficiencies of most current immersion liquid cooling air conditioner cabinets.

[0039] The immersion liquid cooling cabinet mainly includes a housing 100 and a liquid storage box 200. The following is a further detailed introduction to each of the above components.

[0040] like Figure 1As shown, the housing 100 is generally in the shape of a rectangular box, including a box body 130 and a top cover 120. The top cover 120 is hinged to the top of the box body 130 so that the box body 130 can be opened. The interior of the box body 130 is provided with a mounting cavity 110 for accommodating the liquid container 200 and the heating element 300. Figure 2 As shown, the bottom of the installation cavity 110 is provided with the liquid inlet manifold 140, which is used to transport the coolant with higher cooling capacity into the liquid storage box 200. The top of the installation cavity 110 is provided with a liquid outlet manifold 150, which is used to transport the coolant with higher heat content within the installation cavity 110 out. The liquid inlet manifold 140 is provided with a plurality of second liquid inlet joints 141, which are arranged at intervals along the liquid inlet manifold 140. The liquid outlet manifold 150 is provided with a plurality of second liquid outlet joints 151, which are arranged at intervals along the liquid outlet manifold 150.

[0041] like Figure 1 As shown, at least one liquid storage box 200 is installed in the installation cavity 110. Figure 3 As shown, a sealed cavity 210 for mounting a heating device 300 (e.g., a server) and containing coolant is formed within the liquid storage box 200. The liquid storage box 200 is generally in the shape of a rectangular box, and the size and shape of the sealed cavity 210 are adapted to the heating device 300. In other words, the heating device 300 is immersed in the coolant within the sealed cavity 210. In one embodiment of the present application, multiple liquid storage boxes 200 are stacked and installed side by side in the middle of the installation cavity 110, with an opening (not numbered in the figure) at the top.

[0042] like Figure 4 As shown, a flow channel 250 is also installed in the sealed cavity 210, and the flow channel 250 is connected to the liquid inlet manifold 140 and the liquid outlet manifold 150. The installation position of the flow channel 250 corresponds to the heating device 300. Specifically, the flow channel 250 is provided with a liquid inlet 251 and at least one liquid outlet 252. The liquid inlet 251 is connected to the liquid inlet manifold 140; the liquid outlet 252 corresponds to the heating device 300. The setting of the flow channel 250 can preferentially guide the coolant with higher cooling capacity to the heating device 300, further improving the heat dissipation efficiency.

[0043] like Figure 4As shown, the liquid storage box 200 is provided with a first liquid inlet connector 260 for communicating with the liquid inlet manifold 140, and the first liquid inlet connector 260 can be plugged into and matched with the second liquid inlet connector 141. The liquid storage box 200 is also provided with a first liquid outlet connector 270 for communicating with the liquid outlet manifold 150, and the first liquid outlet connector 270 can be plugged into and matched with the second liquid outlet connector 151. Specifically, the first liquid inlet connector 260 is arranged at the bottom of the liquid storage box 200, close to the liquid inlet manifold 140, so as to facilitate communication with the liquid inlet manifold 140. Preferably, the first liquid inlet connector 260 is detachably connected to the liquid inlet manifold 140; and the first liquid outlet connector 270 is detachably connected to the liquid outlet manifold 150. More preferably, the first liquid inlet connector 260 and the first liquid outlet connector 270 are one-way quick-connect connectors, which can realize blind plug connection between the liquid inlet manifold 140 and the liquid outlet manifold 150. The liquid storage box 200 is provided with a flow channel 250 , and the liquid outlet 252 of the flow channel 250 can be closer to the heating element 300 , thereby significantly improving the heat dissipation efficiency.

[0044] like Figure 3 and Figure 4 As shown, a fixing structure 240 for fixing the heating device 300 is provided on the inner side wall of the top of the liquid holding box 200. A mounting structure 230 for mounting the liquid holding box 200 in the mounting cavity 110 is provided on the outer side wall of the top of the liquid holding box 200. Specifically, both the fixing structure 240 and the mounting structure 230 are "I" plate structures. After the heating device 300 is placed in the liquid holding box 200, it can be overlapped on the fixing structure 240. Similarly, the liquid holding box 200 can be overlapped and fixed in the mounting cavity 110 through the mounting structure 230.

[0045] Further, if Figure 4 As shown, a lifting hole 220 for lifting is further provided on the outer side wall of the top of the liquid storage box 200. A liquid level sensor 280 and a temperature sensor 290 are installed on the top of the sealed cavity 210, that is, on the inner side wall of the top of the liquid storage box 200, to facilitate regulating the flow of the coolant.

[0046] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the concept of the present invention. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of the present invention.
