The heat exchanger has a hollow coil through which a liquid is to flow, having a series of adjacent, essentially parallel turns, between which turns members having apertures for the flow of a fluid therethrough, elongated heat conducting paths and in compressed and deformed condition are disposed, for clamping contact with the turns and pressure contact with each other. Examples of such members are woven mesh having strands and expanded metal foil. The members extend across the space encompassed by the turns and thus conduct heat between the turns and a fluid passed through the mesh members in the direction of the axis of the coil, i.e. perpendicular to the planes of the coil turns. The members and coil turns are maintained in compressing contact by a perforated plate at each end of the coil, which plates engage the adjacent members. These plates are held in position by a housing which extends laterally around the members and coil, the housing conveniently being formed of a pair of angular member which may be moved toward each other, to compress the members laterally and the abutting edges then welded, after which the perforated plates may be welded to the angular members.
