Based on the above description in the background art, in the prior art, when a computing service device, such as a server, is subjected to heat dissipation processing, the server is immersed in a cooling liquid, and heat dissipated by the server is taken away by the cooling liquid, so that the server can be ensured to operate in a normal temperature range, and abnormal faults caused by high temperature of the server are avoided. However, at least two or more servers can be placed in the existing immersion cooling cabinet, and at this time, the cooling liquid flowing into the cabinet has a condition of disordered liquid flow field in a partial area, so that the temperature of the partial area is overhigh. Therefore, in view of the problem, the present application provides a cabinet, which can ensure that after the cooling liquid enters the cabinet, the positions of different areas in the cabinet can all form a uniform flow field. The following will describe the cabinet provided in the present application in detail, please refer to fig. 1, where fig. 1 is a schematic structural diagram of an embodiment of the cabinet provided in the present application, and the embodiment of the cabinet includes:
the device comprises a cabinet body 101, a liquid outlet 106, a liquid inlet 105 and a flow guide plate 103 arranged at the bottom of the cabinet body. The cabinet body is internally provided with an accommodating space 102 which can accommodate a cooling device needing cooling; the liquid inlet 105 is arranged at the bottom of the cabinet body 101 and is positioned between the guide plate 103 and the bottom of the cabinet body 101; the liquid outlet 106 is located at the top region of the cabinet 101; the flow guide plate 103 is positioned above the liquid inlet 105, and the plate surface of the flow guide plate 103 covers the bottom of the cabinet body 101; the guide channel 104 arranged on the guide plate 103 can uniformly guide the liquid 1010 entering the guide plate 103 and the cabinet body 101 between the bottom through the liquid inlet 105 to the space above the guide plate 103 and the top of the cabinet body 101 in the accommodating space 102 and form a whole flow field, the liquid 1010 in the accommodating space 102 refrigerates the cooling device in the accommodating space, and when the liquid level reaches the liquid outlet 106, the liquid 1010 is discharged through the liquid outlet.
In this embodiment, the air deflector 103 and the bottom of the cabinet 101 may be disposed in a parallel covering manner, and the specific arrangement manner of the air deflector 103 may be determined according to the actual usage environment structure, for example, the structure of the cabinet or the structure of the cooling device or the cooling requirement. The present embodiment is mainly illustrated in a parallel arrangement.
It should be noted that, when the cabinet provided in the present application is applied in an immersion liquid cooling scenario, the cabinet 101 may be the cabinet 101 of the immersion liquid cooling cabinet, and a device that needs to dissipate heat, such as a server, may be placed in an accommodating space in the cabinet 101. The cooling liquid passes through the inlet enters into the bottom of the cabinet body, the rethread the even water conservancy diversion of water conservancy diversion passageway on the guide plate is to the guide plate top to can be at the guide plate with form even flow field between the cabinet body top, it is right the server refrigerates, and the cooling liquid after being heated can be discharged through the liquid outlet, thereby can guarantee form even flow field and carry out refrigeration treatment to the server all the time in the cabinet, avoid making because the cooling liquid flows to the confusion form chaotic flow field in the accommodation space, lead to local region high temperature in the accommodation space reduces the refrigeration efficiency of server.
