1. A power converter arrangement, comprising:
a housing in which an electronic power converter is arranged;
a cooling duct for cooling the power converter with a cooling liquid is arranged inside the housing;
the cooling duct has a connection respectively for supplying the cooling liquid to the cooling duct and for discharging the cooling liquid from the cooling duct;
the housing has two mating connections which are connected to in each case one of the connections of the cooling duct;
the connections and the mating connections have sealing surfaces which face each other;
the interior of the housing and the cooling duct are sealed liquidtightly via respective sealing devices arranged in the region of the respective sealing surfaces;
wherein
the sealing devices each have two sealing rings;
the two sealing rings of a respective sealing device are spaced apart from each other geometrically;
one sealing ring of a respective sealing device seals the cooling duct liquidtightly and the other sealing ring of a respective sealing device seals the housing liquidtightly; and
wherein a respective annular groove is introduced into the sealing surfaces in the region between the respective sealing rings of the respective sealing device from which a respective outflow duct introduced into the housing leads off and opens out on the outside of the housing.
