| 20090180251 | MULTI-POSITION HOUSING MADE OF METAL EXTRUDED SECTION MEMBER FOR MANUFACTURING A WATERPROOF POWER ELECTRONIC DEVICE - The extruded section forms a tunnel that is substantially rectangular and is provided with fins on at least one side of the rectangle. The fins allow air to flow outside the housing by natural convection in the extrusion directions. A side without fins serves as a base for fastening the housing and as a support for power electronic components of the power electronic device. The fins are machined transversely to the extrusion direction to form notches in the fins. The notches being aligned in succession to allow air to flow outside the housing by natural convection in the optimum direction. | 07-16-2009 |
