Abstract

1439365 Heat sinks; electric component assemblies ROBAND ELECTRONICS Ltd 21 June 1973 29553/73 Headings H1K and H1R A heat sink assembly comprises a metal member thermally coupled to a heat dissipating electrical or electronic component, e.g. a transistor mounted on it and at least one sheet metal heat dissipating member of rectangular outline releasably secured to it with one edge engaging a rectilinear groove therein and another edge engaging a similar groove in the same or in another member. In the Fig. 1 arrangement sheet metal members 4 engage opposed grooves in members 1, 5 and a printed circuit board 3 is attached to portions 1a, 5a of the members and electrically contacts pins 2a extending from transistor 2 mounted on portion la, the assembly being held together by the nut and bolt on which spacers 7, 8 are threaded. A modified assembly comprises a member similar to 1 carrying the transistor and a channel form member the opposed edges of which fit into grooves 1c where they are held by grub screws. Another assembly of box form consists of four metal bars arranged at the corners of a rectangle and joined by sheet metal members constituting walls of the box. The sheet forming the bottom of the box carries the components and is bolted to or formed integral with two of the bars, three other sheets, which may carry switches and other controls, have flanged edges which engage grooves in the bars and are clamped thereto by screws, and_optional sheet metal members which may be perforated and form the ends of the box are screwed to the end faces of the bars.
