摘要： The devices (1) for heat exchange intended for a temperature range of 0-200 C comprise pipes (3) which form windings or coils. The adjacent pipes are jointed together by means of a metal coasting so as to form a tight wall (4). A heat exchanger liquid, preferably water, circulates through the pipes (3). To increase the heat exchanging surface, the wall (4), which is in contact with a gas, comprises heat conductive grooves (5).
