ABSTRACT:
A spiral heat exchanger composed of two separate pipe systems, wherein each heat exchange medium runs in its own pipe system. The heat-emitting and the heat-absorbing pipe sytems are arranged in a tight, intermeshing fashion, in order to improve the heat exchange between the separate spirals, these are interconnected by employing a medium metal. The medium metal is applied by soldering, by dipping the heat exchanger into molten metal or by casting the molten metal on top of the exchanger.
