ABSTRACT:
A solar heating panel provides for improved heat transfer between an absorber plate, which receives solar radiation, and tubes, which carry water to be heated, by clamping the tubes into channels formed in the absorber plate. The clamping is effected through upper bar members acting on the top of the absorber plate, and thermally insulating material supporting the tubes and itself supported by lower bar members below the absorber plate. The lower bar members do not contact either the tubes or the absorber plate. Advantageously, the upper bar members which contact the absorber plate, the absorber plate itself, and the metal frame members to which the upper bar members are secured are all made of corrosion resistant aluminium alloy. The tubes used for carrying the water to be heated may also be made of a similar alloy.
