Abstract

A finned heat sink is constructed from a base having parallel grooves with a latching lip. The fins are individually formed with a retaining boss adjacent one edge which is adapted to mate with the latching lip to secure the fin in the groove. Spacing tabs are formed on the fins to assure uniform parallel spacing between the fins when assembled.
