Patent ID: 7472743

Claim:
A liquid cooling system comprising: a heat-absorbing member defining therein a fluid flow channel for passage of a coolant; a heat-dissipating member; a pump being in fluid communication with the heat-absorbing member and the heat-dissipating member for driving the coolant to circulate between the heat-absorbing member and the heat-dissipating member; an air duct including a bottom portion and a top portion cooperating with the bottom portion to define therebetween a receiving space, said heat-dissipating member and pump being received in the receiving space and are mounted to the air duct, wherein the bottom portion of the air duct has a plate-type configuration and the top portion of the air duct has an inverted U-shaped configuration, and the air duct has a pair of through openings located at two opposite lateral sides thereof, respectively; and a cooling fan located adjacent to the heat dissipating member for producing an airflow from one of said through openings towards the other of said through openings; wherein the heat-absorbing member includes an upper portion and a lower portion hermetically connected to the upper portion, and the fluid flow channel is defined in one of the upper portion and the lower portion; and wherein one of the upper and lower portions of the heat-absorbing member is integrally formed with the bottom portion of the air duct.
