ABSTRACT:
In order to improve the function and to simplify the manufacture of a cooling device for electrical or electronic components, rib-like cooling elements are positioned parallel and at a predetermined distance from one another and are connected to a base plate in heat-transmitting contact. At least two cooling elements are combined into a unitary ribbon-shaped package having a U-shaped profile in cross-section and a web portion which connects the cooling elements. The cooling elements being fixed to the base plate in corresponding longitudinal slots.
