Patent ID: 7907407

Claim:
A heat dissipating device includes a housing ( 1 ) is formed with an exhaust ( 10 ) and an intake ( 33 ); a fan ( 4 ) disposed inside the housing ( 1 ) is corresponding to the intake ( 33 ); a set of fins ( 6 ) disposed inside the housing ( 1 ) is corresponding to the exhaust ( 10 ); said fan ( 4 ) is rotated to circulate cooling air into the set of fins ( 6 ) and expel hot air absorbed by the fins ( 6 ) from the exhaust ( 10 ); wherein an inner wall of the housing relative to the fan ( 4 ) is installed with a first heat pipe ( 5 ) with one end as one condensing portion encircles most of the fan ( 4 ) and the other end as the other condensing portion kept at an end of the housing distant from the fan ( 4 ) and thermally connected to the set of fins ( 6 ); while a middle portion of the heat pipe ( 5 ) served as an evaporating portion is placed on the inner wall of the housing ( 1 ), where a heat-generating electronic component is located, the middle portion of the heat pipe ( 5 ) is also thermally connected to the set of fins ( 6 ).
