<p>6414 INVENTORS: PETER KNAPP and XAVER VOGEL CAN INVENTION: COOLING APPARATUS FOR SEMICONDUCTOR ELEMENTS A cooling apparatus for high-power semiconductors with fluid cooling, especially for track-bound vehicles or railroads and for generator excitation. The disk-shaped semiconductor elements to be cooled are in pressure contact with metallic cooling elements and are arranged, in conjunction therewith, in flow channels. The flow of the cooling agent predominantly is conducted through such cooling elements. Within the cooling elements there are arranged, perpendicular to their contact surface with the semiconductor elements, heat conducting elements in a plug or plate configuration. These heat conducting or dissipation elements produce a turbulent fluid flow. The cooling element base or floor can have a nonuniform or irregular wall thickness. Two substantially identical cooling elements can be in heat conducting contact with one another by means of their heat conducting elements, and a flow conducting plate, arranged between such cooling elements, simultaneously can be employed as electrical contact.</p> |
