Abstract
The invention relates to a power semiconductor module comprising a plurality of power semiconductors that are fixed to a first side of a printed circuit board (), and a cooling device that acts by means of a coolant, on a second side of the printed circuit board (), opposite the first side, the cooling device comprising a plurality of cells through which the coolant is guided. The aim of the invention is to minimise the risk of failure of one such power semiconductor module. To this end, a non-cooled region (d, e, f) is arranged between at least two cells.
