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 server casing 9, 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 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 upper corrugation part of the corrugated plate is used for supporting the heat exchanger 4, and the lower corrugation part is provided with a hollow runner 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 heat exchanger 4 is horizontally placed on the upper side of the supporting plate 5, and a plurality of sliding grooves are formed in the upper side of the heat exchanger 4, so that the server shell 9 can be conveniently placed and drawn out.
The server casing 9 is vertically placed in a chute on the upper side of the heat exchanger 4, and the server 2 is vertically placed inside the server casing 9. The cooling liquid 3 is filled in the whole server shell 9, and the server 2 is immersed in the cooling liquid 3 for heat dissipation and temperature reduction. 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 number of the layers of the server 2 can be one, two or more; the number of the heat exchangers 4 is the same as the number of layers of the servers 2; the number of the support plates 5 is the same as the number of the heat exchangers 4.
