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 (26), and a cooling device that acts by means of a
coolant, on a second side of the printed circuit board (26), 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.
