摘要

A method of manufacturing cooling devices made up of several metal shaped-section elements. The method calls for grooves and beads 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, on one element are pushed into suitably located grooves in a neighboring section, bending inwards and/or deforming plastically so that each bead entering its associated groove is, physically locked in place. Also proposed are shaped-section elements for us in the cooling device and cooling devices manufactured by the method of such elements.
