METHOD OF MANUFACTURING COOLING DEVICES MADE UP OF SEVERAL METAL SHAPED-SECTION ELEMENTS FOR MOUNTING ON SEMICONDUCTOR COMPONENTS, SHAPED-SECTION ELEMENTS FOR USE IN THE MANUFACTURE OF SUCH COOLING DEVICES AND COOLING DEVICES MANUFACTURED BY THE METHOD

摘要

Proposed is a method of manufacturing cooling devices made up of several metal shaped-section elements (1, 2), the method calling for grooves (112, 122, 212, 232) and beads (111, 211, 231) on each of the shaped-section elements to be fitted into each other and connected by the application of pressure in the transverse direction. The outwards-protruding groove walls, designed as beads (121, 223, 233), on one element (1, 2) are pushed into suitably located grooves (122, 212, 232) in a neighbouring section (1, 2), bending inwards and/or deforming plastically, so that each bead entering its associated groove is physically locked in place.
