A heat exchanger in which the main component is formed of a plurality of elongated strips of rigid heat conductive material. The strips are generally transversely aligned and wound into a coil formation in which each of the surfaces of each strip is disposed in facing relation to the opposite surface of an adjacent strip in the coil. Each pair of facing surfaces is ridged to provide passage defining portions and force transmitting portions with certain of the strips having both end edges thereof sealingly secured to the corresponding end edges of an adjacent strip so as to define a longitudinal fluid passage having a coil formation other of the strips have both end edges thereof disposed out of sealing engagement with corresponding end edges of the adjacent strip so as to define a transverse fluid passage. The force transmitting portions of each pair of facing surfaces are disposed in force transmitting relation with respect to one another so that forces created by the fluid pressure and temperature conditions within the fluid passages tending to deform the strips are resisted to thereby prevent deformation which would otherwise occur in the absence of the force transmitting relationship and permit the utilization of wall thicknesses less than that required to be self-sustaining in order to prevent such deformation. By providing a cyclical fluid infeed, a peristaltic action through the coil formation fluid passage is achieved.
