Abstract
1361566 Making heat dissipators STAVER CO Inc 10 March 1972 11416/72 Heading B3A [Also in Division H1] A heat dissipator (Figs. 1 and 2) for an integrated circuit or other semi-conductor device having L-shaped heat conductive tabs extending from opposite sides of its, e.g. moulded plastics casing is fabricated from a single metal sheet by cutting and bending. It comprises a base portion 26 from which two pairs of fingers are bent down to form a cradle for the device, one pair 46, 48 resiliently clamping the device while the other pair 52, 54 are in heat conductive contact with the mating conductive tabs of the device. Heat is dissipated via two wings 24, 28 bent up from the base. Parallel pairs of cuts may be made in the wings and the intervening strips pushed out of the general plane of the wings to increase convective cooling. Radiation from the dissipator, which may be of beryllium copper or aluminium, may be increased by anodizing or by painting it matte black.
