Device for cooling an electrical component and production method thereof
First Claim
1. A device for cooling an exothermic electrical component, of the type comprising a metal member forming a radiator thermally coupled to a metal mass of the component forming a heat dissipating mass of the component, wherein the radiator is thermally coupled to the dissipating mass by at least one heat sink formed by an autogenous weld between one face of the dissipating mass, called the dissipating face, and one face of the radiator, opposite each other.

Abstract
In a device for cooling an electrical component and to the production method thereof, the inventive device includes a metallic radiator-forming member which is thermally connected to a metallic mass of the component that forms a heat-dissipating mass. The radiator is thermally connected to the dissipating mass by at least one heat sink which is formed by an autogenous weld between one face of the dissipating mass, known as the dissipating face, and one face of the radiator, which are facing one another. The invention can be used to cool electronic components, for example, in power electronic modules.
