  • Patent number: 12245394
    Abstract: An electronic power converter is in a housing of a power converter arrangement. A cooling duct for cooling the power converter with a cooling liquid is inside the housing. The cooling duct has a connection supplying the cooling liquid to the cooling duct and for discharging. Mating connections are connected to 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 is sealed via sealing devices each have two sealing rings spaced apart from each other. First sealing rings seal the cooling duct and the other sealing rings seal the housing. Annular grooves as outflow ducts in the housing lead off and open out on the outside of the housing and are introduced into the sealing surfaces in the region between the sealing rings.

  • Patent number: 12096577
    Abstract: A power semiconductor arrangement has a switching facility, a housing, having a load connection facility for connecting in an electrically conductive manner to an external supply line and having a first plug-in connecting facility for plug-in connecting to an external second plug-in connecting facility. The housing has a first opening through which a connecting facility for connecting the load connection facility and the associated external supply line is accessible. A cover facility for covering the first opening is on the housing so as to be mechanically movable from a first end position into a second end position and has a first locking facility which cooperates with the external second plug-in connecting facility, whereby the first opening is closed with the cover facility as long as it is in its first end position, as long as the external second plug-in connecting facility is inserted into the first plug-in connecting facility.
