[0044] The working process in this embodiment is as follows:

[0045] During installation and use, the detachable module is taken out through the auxiliary disassembly part 3, and the power supply is installed in the power supply installation position 17, with the power switch facing upwards.

Remove the mainboard I / O interface baffle 7, fix the mainboard to the mainboard installation position 16 with screws, and the mainboard and power supply are conventionally connected. The lines involved in the connection can be immersed in mineral oil. Close the drain port 15, pour mineral oil into the box body 1, covering the liquid outlet 9, connect the mainboard and the chassis power supply and USB and other button integrated parts 8 through conventional wires, and then reassemble the detachable module. Turn on the host power supply, the heat dissipation device fan and the volume pump 13 to determine whether the equipment is operating normally.
