Isothermalised heat sink

摘要

The aim is to provide an isothermal heat sink, which is simple and inexpensive to produce, for cooling components which generate waste heat, in particular power semiconductors. For this purpose, the heat sink (1) has on its mounting side a groove (2) on top of which a semi-finished heat tube constructed as an elongated cover (6) is laid and welded to the groove (2) to form a complete heat tube. The groove (2) and cover (6) respectively have suitable internal surface structures (5a, 5b). <IMAGE>
