Abstract

An inexpensive method is described of generating a heat sink for thermal conduction modules (TCMs), wherein aluminum plates, provided with spacers, are electrowelded to each other to form a heat sink, through which cooling air is blown. The aluminum plates may be contoured or have ribs to prevent a whistling effect between the aluminum plates. The method is described below with reference to the figure. Aluminum plates 1, having a thickness of 1 mm, are bent at two facing edges. The bent portions 2, 3 serve as spacers. A number of aluminum plates thus treated are stacked and interconnected along the spacer edges by electrowelding in a protective gas atmosphere. The face of the heat sink, that is placed on the TCM and that is increased by having four aluminum ribs 4 welded to it, is subsequently ground.

Heat Sink for Thermal Conduction Module

An inexpensive method is described of generating a heat sink for thermal conduction modules (TCMs), wherein aluminum plates, provided with spacers, are electrowelded to each other to form a heat sink, through which cooling air is blown. The aluminum plates may be contoured or have ribs to prevent a whistling effect between the aluminum plates. The method is described below with reference to the figure. Aluminum plates 1, having a thickness of 1 mm, are bent at two facing edges. The bent portions 2, 3 serve as spacers. A number of aluminum plates thus treated are stacked and interconnected along the spacer edges by electrowelding in a protective gas atmosphere. The face of the heat sink, that is placed on the TCM and that is increased by having four aluminum ribs 4 welded to it, is subsequently ground. The heat sink is fixed to the TCM by means of screws (not shown). For cooling the TCM, air is blown through the spaces between the aluminum blocks.
