ABSTRACT:
A cooling unit for a number of power semiconductors is formed by a quadrangular tube to which the power semiconductors are secured at an exterior with good thermal conductivity, in an equipping region of the tube. The quadrangular tube has a coolant inlet and a coolant outlet. The quadrangular tube contains a laminarization unit disposed in a region following the coolant inlet, this region overlapping the equipping region. The laminarization unit produces a substantially laminar flow of the coolant in the tube within the aforementioned region. In a region between the laminarization unit and the coolant outlet, the quadrangular tube contains a number of turbulence-producing elements for introducing turbulence into the coolant flow.
