ABSTRACT:
A heat exchanger of the type in which multiple layers of helically coiled tubes surround a core tube, has spacers between the layers which are constituted by elongated bodies provided with seats receiving successive tubes of each layer and having dovetail formations enabling the bodies of each layer to be connected to those of the adjoining layers. The bodies thus act as spacers for the successive turns in each layer and for the successive layers and retain the turns specifically at the ends of the coils to facilitate positioning thereof with respect to the core tube and/or the housing.
