Abstract

1296578 Semi-conductor devices GENERAL ELECTRIC CO 14 Oct 1970 [28 Nov 1969] 48737/70 Heading H1K A heat dissipator comprises a mounting portion joined to a second portion having heat dissipating extensions, the mounting portion being of a material having a higher thermal conductivity than the material of the second portion and the heat transfer between the two portions being improved by a conductive fluid applied to their abutting faces. As shown, Fig. 1, the dissipator comprises a copper plate 15 bolted to an aluminium extrusion 17 having fins 19. The surface between the plate 15 and the extrusion 17 is treated with a conducting fluid 16. An SCR 13 is secured to the centre of the plate 15. In an alternative arrangement, Fig. 2 (not shown), an SCR (25) is sandwiched between the copper plates (15) of two such heat dissipators which are clamped together by means of insulated bolts (33). The copper plates (15) are provided with central projections (31) which enter corresponding recesses (29) in the SCR housing.
