ABSTRACT:
The heat exchanger (1) comprises a plurality of coils (6.sup.1 -6.sup.5) of tubing of a flexible plastics material, the coils being of cylindrical conformation and of differing diameters each coil being mounted coaxially about the coil of next smaller diameter on an array of longitudinally arranged slat members (10) lying in spaced radial planes about the coil axis. The coils may be supported on the slat members by being received within recesses (11) in the slat edges and the slat members in turn are supported in similar manner on the coil of next smaller diameter. The tubing may be clipped into the recesses, and held therein, by virtue of the tubing or the slat members, or both being made of resiliently deformable material. Suitable material is a polyolefin or a polyvinyl material suitably a polyhalocarbon material where corrosion resistance is required. In use the flow of heat exchange fluid longitudinally through the coils is preferably countercurrent to the flow of fluid over the coils.
