    摘要: A device for dissipation of the thermal power loss of an electronic or electromechanical component (10) is proposed, in which an adequate cooling surface area is available. To obtain the largest possible cooling surface area at low assembly outlay, the components (1) have a heat-conducting connection with a metal-coated surface of a printed circuit board (2). The coated surface parts (5, 7) protrude as far as a connecting segment (10; 10a, 10b, 10c) of a housing (8, 9) that entirely or partially surrounds the printed circuit board (2). At least one connecting segment (10, 10a, 10b, 10c) of the housing (8, 9) is embodied in crowned fashion on its surface such, that upon fastening of the housing (8, 9) to the printed circuit board (2), a durable contact pressure between the housing (8, 9) and the printed circuit board (2) is exerted by the deformation of the crowned surface.
