A heat sink (10) for semiconductor components is made of extruded aluminium and has cooling ribs (26) which extend upwards from a baseplate (12) at a distance from one another. The cooling ribs (26) are hollow profiled sections with two mutually parallel side walls (28) and transverse walls (30, 31, 32) which interconnect the latter. The rib ratio can therefore be increased further without increasing the labour expended on manufacturing the heat sink. <IMAGE> |
