Title: Mechanical heat exchange joint

Abstract: A heat-conducting joint suitable for solar heat collectors. A tubular metal member carries heat-transfer fluid. A sheet metal member is in thermal contact with said tubular member and one of the members is pre-curved in a plane perpendicular to the surface of the sheet into a wave shape substantially consisting of a plurality of long radius arches joined by short radius cusps. Means are provided for first securing the other member while straight to the one member near its ends in a manner to prevent sliding of the other member on the one member. Means are provided for then securing said other member against the one member at the short radius cusps, whereby the two members are pressed together elastically along at least one line of contact for efficient heat conduction between them.
