ABSTRACT:
To produce a heater or heat exchange element, a wire coil is wound around a pipe, in a stressed condition. When the pipe is pressed on to a heat-transfer and support element, the projections formed by the wire coil penetrate into the support element and are anchored therein. Suitable selection in respect of the hardness of the materials used makes it possible for the portions of the wire coil which are remote from the support element to be pressed flat until they come into at least approximately contact with each other, producing a form of protective shell which also improves heat transfer between the pipe and the support element.
