the heat dissipation fin 421 can also transfer the heat received by the soaking plate 41 until it is transferred into the liquid storage member 44, and the liquid storage member 44 stores the cooling liquid, so that the cooling liquid is absorbed by the cooling liquid in the liquid storage member 44, and part of the cooling liquid in the liquid storage member 44 can flow into the heat absorption pipe 45 through the liquid outlet pipe 452 and the liquid guiding pipe 451;
