Abstract

A heat dissipation device (1) includes a chassis (10) and a fin member (20). The chassis is formed as a single unit by extrusion, and includes a top surface (11). Four parallel ribs (13) are formed on the top surface. A pair of slots (14) is difined in the top surface, adjacent the two outermost ribs. The slots are adapted for connection to a conventional fan frame (50). The fin member defines four grooves (21) and a channel (22) therethrough. The channel is between the innermost grooves, and is adapted to interferentially receive a conventional heat sink clip (60). The four grooves interferentially receive the ribs of the chassis, thereby securely attaching the fin member to the chassis.
