摘要

A cooling device includes a heat sink ( 10 ), a fan ( 30 ), and a fan duct ( 50 ) covering the heat sink and fan therein. The heat sink includes a base ( 12 ) defining at least a through hole ( 18 ) at each of two opposite sides thereof. The fan duct comprises a top wall ( 52 ) and two side walls ( 54 ). A mounting portion ( 60 ) extends outwardly from a bottom of each side wall and has at least a tube ( 64 ) defining a mounting hole ( 640 ) in an outer wall thereof. A plurality of pins ( 70 ) extends through the through holes into the tubes. The pins have retaining rings ( 74 ) abutting against a bottom surface ( 120 ) of the base of the heat sink, and hooks ( 76 ) locked in the mounting holes.
