Patent ID: 7147043

Claim:
A liquid cooling system for dissipating heat generated by an electrical component, the liquid cooling system comprising: a cooling body defining a passageway filled with liquid coolant, and an inlet and an outlet both in communication with the passageway, the cooling body comprising a cylinder with a hollow portion therein and a plurality of first mounting tabs extending from opposite first and second ends thereof, and first and second lids being hermetically attached to the first and second ends, respectively, and having a plurality of second mounting tabs engaged with the first mounting tabs of the cylinder; a pump located at the hollow portion, the pump defining an exit connected to the inlet by a tube, and an entrance connected to the outlet by another tube, thereby forming a cycle loop together with the passageway; and a plurality of cooling fins arranged at the hollow portion; wherein the coolant is capable of transferring the heat from the contact portion to other portions of the cooling body via flowing in the passageway, and the heat is then conducted to the cooling fins for dissipation.
