Electronic component e.g. power transistor, cooling unit, has base unit, with which component to be cooled is thermally connected, and cooling units that are pencil-shaped and are material-conclusively connected with base unit by soldering

摘要

The unit has a base unit (14), with which a component or a module to be cooled is thermally connected. A set of cooling units (22) is connected with the base unit and stays away from the base unit. The cooling units are pencil-shaped and are material-conclusively connected with the base unit by soldering. The cooling units are different or same in its length, its diameter, its geometry and its material.
