Abstract
A solar heat collecting device of the flat panel type, a process for its manufacture and parts thereof, made of extruded profiles in particular of aluminum or aluminum alloys. The device comprises a casing accommodating a heat collector assembly comprising a plurality of elongate extruded heat collector bodies, side by side, each having a tube co-axial with its axis of extrusion, flanked on each of its opposite sides integrally by an extruded web and further comprising a manifold at each end to which the respective tube ends are sealingly and communicatingly brazed. The edges of the adjoining webs of adjoining elongate bodies overlap slightly but are movable free of mechanical constraint or mutual attachment in relation to one another. Together the elongate bodies present the incoming solar radiation with a substantially plane uninterrupted area for absorption.
