Abstract: A circuit carrier for holding at least one electrical power component is disclosed. The circuit carrier including a heat sink for holding and for cooling the power component. The heat sink having a surface. The circuit carrier includes a copper layer for mechanically connecting the heat sink to at least one copper plate, where the copper layer includes copper or a copper alloy and is cold-gas-sprayed or sintered on the surface of the heat sink. The circuit carrier also includes at least one copper plate for mechanically and electrically connecting the power component to the copper layer. The copper plate includes copper or a copper alloy and is arranged directly on a surface of the copper layer facing away from the heat sink and is areally, mechanically and electrically conductively connected to the copper layer.

Abstract: A cooling device includes an aluminum heat sink and at least one nickel sheet segment. The nickel sheet segment is connected to the aluminum heat sink by a solder layer. The cooling device includes a securing surface for securing and for heat absorption. The securing surface being formed by that side of the nickel sheet segment which faces away from aluminum heat sink. The aluminum heat sink is formed from a plurality of aluminum sheets which are stacked one above another and are connected to one another. At least one aluminum sheet includes cutouts which form a cooling channel covered by at least one of the aluminum sheets. Furthermore, a method for producing a cooling device and also a power circuit comprising a heat sink as described here are presented.
