Patent ID: 7600558

Claim:
A cooler, comprising: a cooler ( 3 ) comprises a base ( 32 ), a set of radiator fins ( 33 ) and a plurality of heat pipes ( 31 ); wherein the base ( 32 ) has a multitude of retaining slots ( 322 ) on a top surface thereof for respectively retaining the radiator fins ( 33 ) and enlarging the heat conducting areas; the fins are wider upwards for heat dissipation; the base ( 32 ) has a recess ( 324 ) on a bottom surface thereof; the bottom surface has a shape corresponding to a shape of an upper side of a predetermined heat-generating element ( 5 ); the base ( 32 ) has a plurality of holes ( 325 ); the heat pipes ( 31 ) pass through the base ( 32 ) horizontally through the holes ( 325 ) so that parts of the heat pipes ( 31 ) are exposed in the recess ( 324 ); the parts of the heat pipes ( 31 ) exposed in the recess ( 324 ) have flat bottom surfaces for contacting the heat-generating element ( 5 ); Lower ends ( 31 a ) of lower terminals of the heat pipes ( 31 ) are exposed out of the holes ( 325 ) of the base ( 32 ) for heat dissipation, connecting the heat pipes ( 31 ) and the base ( 32 ); the heat pipes ( 31 ) are bent and folded so that the other terminals ( 31 b ) thereof pass through the set of radiator fins ( 33 ) in the wider upper ends thereof in the same horizontal direction; whereby the heat pipes ( 31 ) and the radiator fins ( 33 ) are connected; since parts of the heat pipes ( 31 ) are exposed within the recess ( 324 ), the heat-generating element ( 5 ) embedded therein will contact the heat pipes ( 31 ) directly, whereby the heat generated in the element ( 5 ) will be conducted quickly through the heat pipes ( 31 ) to the radiator fins ( 33 ); therefore, the heat-dissipation efficiency is enhanced.
