Heat sink assembly having a fan mounting device

摘要

A heat sink assembly ( 100 ) includes a heat sink ( 10 ) having a plurality of fins ( 14 ), a fan handle ( 24 ) buckled with the fins and a fan ( 30 ) mounted on the heat sink ( 10 ) via the fan handle. The fan handle includes a retaining body ( 26 ) clasping two adjacent fins having a space therebetween. A screw ( 22 ) is extended through the fan and into the space of the two adjacent fins. The retaining body includes a pair of opposite lateral walls ( 260 ) clamping opposite sides of the two adjacent fins, for preventing the two adjacent fins from being over expanded outwardly during the insertion of the screw into the space.
