Cooler for a power semiconductor, has fan blowing onto at least two heat exchange surfaces, at least one of which is thermally connected to the semiconductor

摘要

A cooler (14) for a power semiconductor comprises a fan (26) blowing air onto at least two angled heat exchange surfaces (15,20) of which at least one thermally contacts a power semiconductor (30). The fan is held (22) to at one of the surfaces so that the fan extends into the internal space.
