Abstract
Abstract A semiconductor device comprises semiconductor elements arranged side by side and provided with hollow cooling bodies. The cooling bodies are joined to each other by a connection conduit for the coolant which is flexible and which insulates the cooling bodies from each other electrically. The connection conduit comprises a tube of insulating inorganic material and a bellows of metallic material fixed to each end of the tube.
