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.

Abstract: A cooling element and connector comprises a metallic body formed by a good heat and electricity conducting material. Ceramic tubes are housed axially in orifices of the body, and are connected to manifolds for circulation of a cooling fluid. The tubes contain turbulating devices designed to channel the fluid according to a turbulent flow with a helicoidal trajectory. The heat exchange is optimum due to a metallic alloy with a low melting point inserted into the annular gaps arranged between the tubes and the corresponding orifices of the body. Assembly of the manifolds on the body is performed by means of screws inserted into the opposite ends of the turbulating devices.
