  • Heat dissipation device
    Patent number: 6926071
    Abstract: A heat dissipation device (10) includes a base (12) and a plurality of fins (14). Each fin includes a heat dissipating post (14) and a heat conducting tab (18). Each heat dissipating post is made by rolling up a metallic slice and thereby defines a through hole therein. Each heat conducting tab includes an engaging part (18a) attached on the base and a medial part (18b) extending from the corresponding heat dissipating post. The medial parts thermally connect the engaging parts and the heat dissipating posts, and mechanically separate the engaging parts from the heat dissipating posts; thereby the through holes are allowed to be exposed at opposite ends of the heat dissipating posts.
