Detailed Description

Fig. 1 and fig. 2 show a schematic structural diagram of a first embodiment of the liquid cooling server cabinet of the present invention, which includes a cabinet body 1, and a server 2, a heat exchanger 4, a cooling liquid 3, a spraying device and a supporting plate 5 which are arranged in the cabinet body 1. The supporting plate 5 is horizontally arranged in the cabinet body 1 and divides the space in the cabinet body 1; the server 2 is placed on the support plate 5; a hollow runner is arranged on the supporting plate 5; the cooling liquid 3 is arranged at the bottom of the cabinet body 1; the heat exchanger 4 is horizontally placed in the cooling liquid 3 in the cabinet body 1 to exchange heat and reduce temperature of the cooling liquid 3 at the bottom of the cabinet body 1, and the cooling liquid can be completely immersed or partially immersed. The spraying device comprises a spraying pipeline 7, a spraying head 6 and a liquid pump 8; the input end of the liquid pump 8 is connected with the cooling liquid 3 through a spray pipeline 7, and the output end of the liquid pump is connected with the spray header 6 through the spray pipeline 7; the spray header 6 is arranged at the upper part of the server 2.

The supporting plate 5 is a corrugated plate, the left side and the right side of which are fixedly connected with the cabinet body 1, and the space in the cabinet body 1 is divided into a plurality of layers. The corrugated plate is provided with a sliding groove 12, which is convenient for placing and drawing in and out the server 2. Hollow flow channels are reserved at the lower corrugations so as to facilitate the outflow of the cooling liquid 3. This backup pad 5 adopts the ripple shape can play the effect of converging coolant liquid 3, prevents that coolant liquid 3 from splashing at the downflow in-process, reduces the cooling effect.

The server 2 is placed vertically at the chute 12 of the corrugated plate. The server 2 comprises a server mainboard, a hard disk group, a power pack and a panel; the server mainboard and the power pack are respectively arranged on the panel; the panel is provided with an I/O port, a power supply port and a hard disk connecting port, and hard disks in the hard disk group are electrically connected with the main board through the hard disk connecting port. In order to facilitate heat dissipation, the server 2 is not provided with a sealed shell, so that the cooling liquid 3 can be directly subjected to heat exchange with the heating elements on the server 2, and the heat exchange efficiency is improved. The hard disks in the hard disk group are solid state hard disks or helium gas hard disks, and both the solid state hard disks and the helium gas hard disks can work normally in the cooling liquid 3. The servers 2 may be two or more layers.

When the number of the servers 2 is two-layer, the low-temperature cooling liquid 3 in the cabinet body 1 is conveyed to the upper part of the server 2 on the top layer through the spray pipeline 7 under the action of the pumping force of the liquid pump 8, is sprayed on the server 2 through the spray head 6, is in contact heat exchange with the heating element on the server 2, then flows out through the hollow runner 11 at the lower end of the corrugated plate under the action of gravity, and continues to cool the server 2 on the next layer. The high-temperature cooling liquid 3 after the two heat exchanges flows downwards under the action of gravity, and exchanges heat with the low-temperature medium in the heat exchanger 4 to cool, and the cooled low-temperature cooling liquid 3 continues to perform the next cooling circulation.
