Cooling device for electrical or electronic devices

In a cooling device for electrical or electronic components, wherein the rib-like cooling elements (3) of thermally highly conductive material are thereby connected to the components to be cooled (1a, 1b, 1c) supporting base plate (2) that the web-like feet (3a ) of the cooling elements (3) in slot-like longitudinal grooves (4) of the base plate (2) are anchored, the anchoring is improved in that the groove-shaped recess (4a) in the Längsnutenseitenwand (4c) in the free cross section is formed and dimensioned such that the permanent indentation of the side part of the profile foot (3a) without substantial bending deformation of the longitudinal groove (4) projecting profile leg of the cooling elements (3).
