BS>The heat exchanger comprises a plurality of ducts parallelly positioned and connected at the ends by headers. Each duct encloses at least one helical coil tube, the helicoidal axis is aligned with the duct axis and the ends of this coil tube passes directly through the wall of the duct. In another form one end of each coil tube passes directly through the duct wall, while the other is connected to the end of a tube that passes axially back through the coil and then directly through the duct wall. The ducts are formed by tubular pieces welded together in such a way that each coil end is held in place by two adjacent tubular pieces, which are provided at the ends with semi-circular slots for this purpose.
