Plate-shaped heat-sink module for capacitor, comprises edge structures that allow coupling to similar modules in defined orientation

摘要

The module is polygon-shaped, e.g. square-shaped, with a heat-generating element fixed to its top side, and cooling fins arranged on its underside. The outer edges have complementary surface structures that care sued to assemble several similar modules in one plane. The surface structures allow one module to be inserted in only one orientation w.r.t another module.
