Zusammenfassung:	A cooling element for cooling a plurality of power semiconductor modules including power semiconductor units including a plate made of thermally conductive material. The plate includes channels for carrying a flow of a cooling liquid. The channels include a main supply channel converging in a direction of the flow of the liquid, a main discharge channel diverging in the direction of the flow of the liquid, a plurality of supply channel branches branching from the main input channel, a plurality of discharge channel branches merging to the main discharge channel, and a plurality of power semiconductor unit cooling channels connecting the supply channel branches and the discharge channel branches. Each power semiconductor unit cooling channel is arranged to cool one power semiconductor unit. The plate includes openings for thermally separating the power semiconductor modules from each other.
