Patent ID: 7379301

Claim:
A liquid cooling system for a heat-generating electronic component comprising: a base defining therein a center opening and slots, and channels communicating the opening with the slots; a heat-dissipating member mounted to the base, and defining therein a plurality of fluid flow channels for passage of a coolant; a pump having a chamber receiving the coolant therein, and being mounted in the opening and being in fluid communication with the slots of the base and the channels of the heat-dissipating member via the slots, the pump comprising a bottom plate having a top surface and a bottom surface, and a rotor received in the chamber and engaging with the bottom plate, the rotor having a cylindrical wall and a substrate connecting with a bottom end of the wall, wherein the top surface of the bottom plate of the pump contacts with the coolant in the chamber, the bottom surface of the bottom plate contacts with the heat-generating electronic component for absorbing heat generated by the electronic component.
