Wärmeableitendes Gehäuse zur Aufnahme von elektrischen oder elektronischen Bauteilen

摘要

The invention relates to a housing designed to accommodate at one printed board (12) having at least one electrical or electronic component (13) with a heat contact element (14). The housing consists of a light metal extruded section (1) forming a single piece and having accommodating contours (10, 11) in its interior for the printed board (12) and a contact surface (15) to support the heat contact element (14) of the appropriate component (13). In order to produce automatic heat contact between the heat contact element (14) and the contact surface (15) in the interior of the housing once the latter has been equipped, at least one of the sides (3, 4) can be expanded or is expanded in relation to the base side (2) and/or the opposite side of the extruded section in a starting position. By plastically deforming and directing said side (2) to its final position in its connection zone, pressure is automatically exerted upon the component (13) to be cooled, whose heat contact surface (14) is thus pressed against the contact surface (15) in the housing.
