ABSTRACT:
An exemplary encapsulated high-voltage switch is disclosed which contains a heat-generating current conductor, a metal encapsulation surrounding the current conductor, and a cooling element. A cooler of the cooling element is fixed on a part of the encapsulation that is embodied as a mounting plate, and has cooling ribs arranged outside the encapsulation. In a section of the cooler that is embodied as a cooling block, at least a portion of the cooling ribs is arranged parallel to the mounting plate and is held on a heat distributor fixed to the mounting plate in such a way that on both sides of the heat distributor in each case one of two groups of cooling channels arises, in which the cooling channels are in each case arranged in the manner of a sandwich. The cooling channels can, for example, be oriented in a manner inclined relative to a horizontal axis of the switch.
