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.
Claims10
A cooling element and connector comprising a body made of a good heat and electricity conducting metallic material, and forming a heat sink through which a cooling fluid flows, said body having a support face of an electronic power component constituting the heat source, and comprising:
- a plurality of orifices through which fluid circulation tubes pass axially, each tube having a diameter slightly smaller than that of the orifice, and being made of an electrical insulating and good heat conducting material,
- an annular gap arranged between each tube and the corresponding orifice, said gap being filled with a metallic alloy enabling an optimum heat exchange between the heat source and the cooling fluid, insertion of the alloy being performed via a filling orifice arranged in the body.
