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.

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 appropriate liquid pump 8 is selected to ensure the appropriate flow rate of the cooling liquid 3, so as to control the height of the liquid level of the cooling liquid 3 in the server housing 9, so that the heating elements of the server 2 are completely immersed in the cooling liquid 3 to fully dissipate heat.

The cryogenic cooling liquid 3 in the cabinet body 1 is under the suction effect of liquid pump 8, carry to the 2 upper portions of server on top layer through spray piping 7, rethread shower head 6 sprays on server 2 and is full of whole server housing 9, heating element submergence contacts the heat transfer in the coolant liquid 3 in server housing 9 on server 2, coolant liquid 3 after the intensification flows to heat exchanger 4 surface and carries out the heat transfer cooling with the low temperature medium in the heat exchanger 4 through the drain hole, cryogenic cooling liquid 3 after the cooling flows out through fretwork runner 11 of buckled plate lower extreme under the effect of gravity, continue to be the heat transfer cooling of next floor server 2.
