Abstract: A design of finned units, intended for example for thermal regenerators, heat exchangers or burners for liquid fuel. The finned units are manufactured by simultaneous spiral winding of a strip forming fins and a spacer element forming a distance between the fins. The spacer elements are wholly or partially removed when fixing elements have been introduced in a number of holes distributed about the circumference. The cross-sectional area of each fixing element is equal to or smaller than the cross-sectional area of the corresponding holes in the fins. As a consequence thereof each fixing element prevents movement of the fins exclusively in a plane perpendicular to said fixing element.

Abstract: A cover assembly is used for retaining members such as the heat exchanger elements of a heat exchanger in clamping engagement with a diaphragm which is interposed therebetween. The cover assembly has an inner plate and an outer plate which form a chamber within which a fluid medium is contained. The fluid is pressurized to provide force distributed uniformly over the surface of the inner plate, thereby enabling this plate to resist forces which would otherwise tend to cause it to buckle, and assuring clamping pressure to clamp the members together over their entire contact area to enable good thermal transfer therebetween.
