Patent ID: 7746650

Claim:
A cooling system for an electrical component, comprising: a board-shaped mounting substrate on which the electrical component is mounted on a side of the substrate; a heat sink configured as bent sheet-metal part assigned to the electrical component disposed on the same side of the substrate as the electrical component, wherein the bent sheet-metal part has at least one heat sink element extending in a longitudinal direction oriented obliquely to a plane of the substrate; a thermally conductive layer implemented on the substrate to thermally connect the heat sink with the electrical component; and a solder joint between the bent sheet-metal part and the thermally conductive layer, wherein the bent sheet-metal part has a U-shaped section with legs and ends of legs are connected to the thermally conductive layer based upon the solder joint, wherein the U-shaped section has end faces, and wherein the at least one heat sink element is formed by upwardly bent sheet-metal sections on a horizontal portion of each end face of the U-shaped section.
