[0035] When the immersion liquid cooling device of this embodiment is in use, first, place the server inside the liquid pool 20, inject low-temperature coolant into the liquid pool 20 through the liquid inlet 203 on the liquid pool 20. The low-temperature coolant is injected through the liquid distribution pipe 205 at the bottom of the liquid pool 20 and flows upward through the server to take away the heat energy generated by the server. The high-temperature coolant after absorbing the heat energy generated by the server flows from the upper end of the liquid pool 20 to the liquid return tank 208 and flows out of the liquid pool 20 through the liquid outlet 204 communicated with the liquid return tank 208. Therefore, the heat exchange efficiency of the immersion liquid cooling device of this embodiment is higher, and the overall temperature difference control is more uniform.
