Abstract:
A heat dissipating device comprising:a heat dissipating fin unit made of a heat-conductive material; a heat dissipating fan unit mounted on said fin unit and operable so as to generate cooling air for cooling said fin unit; a heat exchanger including a hollow contact body that is made of a heat-conductive material, that is disposed adjacent to said fin unit, and that contains an amount of working fluid therein, said contact body being adapted to be disposed in contact with a heat generating component, said heat exchanger further including a delivery pipe that is connected to said contact body to permit exit of the working fluid from said contact body, and a supply pipe that is connected to said contact body to permit entry of the working fluid into said contact body, said supply pipe being mounted to said heat dissipating fin unit to permit cooling of the working fluid in said supply pipe; and a pump connected to said delivery pipe and said supply pipe and operable so as to draw the working fluid from said contact body via said delivery pipe and to supply the working fluid into said contact body via said supply pipe; whereby, the working fluid is cooled by said fin unit while passing through said supply pipe, wherein said pump is coupled to and is driven by said fan unit, wherein said fan unit is mounted on top of said fin unit, said pump being mounted on top of said fan unit.
