Claim:
1. A water-cooling module comprising a main body, the main body having a receiving space and a water room partitioning hoard, the receiving space being partitioned by the water room partitioning board into a pump chamber and a heat exchange chamber, the pump chamber and the heat exchange chamber communicating with each other through at least one communication section, a submersible pump unit being disposed in the pump chamber, a heat transfer unit being disposed in the heat exchange chamber, a cooling fluid being filled up in the main body to circulate within the pump chamber and the heat exchange chamber such that the bottom and sides of the pump chamber or the heat exchange chamber are within the cooling fluid; wherein the submersible pump unit is entirely immersed in the cooling fluid, and the submersible pump unit has a rotor assembly and a stator assembly being received together in the pump chamber so that the stator assembly is cooled by the cooling fluid, the stator assembly being enclosed in a waterproof layer, the stator assembly and waterproof layer being immersed in the cooling fluid with the rotor assembly; wherein the stator assembly has multiple silicon steel sheets, multiple windings and a circuit board, the silicon steel sheets and the windings and the circuit board being enclosed in the waterproof layer and cooled by the cooling fluid.
