Abstract
A cooling device for power electrical components which have electrodes includes a heatsink including a circuit in which a cooling fluid can flow and having a first side for exchange of heat with the component to be cooled. An electrically insulative and good heat conductor material plate is disposed between the first side of the heatsink and a first side of an electrical connection. A second side of this electrical connection makes thermal and electrical contact with one electrode of a component. The heatsink and the electrical connection are mechanically joined so that the device forms a compact assembly.
