Heat sink for an electronic power component
First Claim
1. A heat sink (10) comprising a body (12) made of a metallic material having a surface intended to support an electronic power component (14), the body comprising a plurality of openings (22) axially crossed by tubes (24) of circulation of a cooling liquid, each tube being formed of a material with a good thermal conductivity and being separated from the body by a ring-shaped electric isolation layer formed of a compressed powder of at least one material with good electric isolation and thermal conduction properties.

Abstract
A heat sink comprising a body made of a metallic material with good thermal and electricity conduction properties having a surface intended to support an electronic power component forming a heat source. The body comprises a plurality of openings axially crossed by tubes of circulation of a cooling liquid. Each tube being formed of a material with a good thermal conductivity and being separated from the body by a ring-shaped electric isolation layer formed of a compressed powder of at least one material with good electric isolation and thermal conduction properties.
