ABSTRACT:
The solar heater comprises an elongate concave reflector having a reflecting surface consisting of two interconnecting portions which are substantially symmetrical about a longitudinal plane of the reflector. Each portion in section is of substantially compound parabolic curvature. A heat absorbing device is disposed within the space defined by the reflector substantially symmetrically about said longitudinal place. The heat absorbing device includes a duct for receiving and conveying a heat transfer medium, said duct having surfaces in the form of plates extending laterally of said plane towards side regions of the two portions. Side plates extend downwardly from the distal edges of the laterally extending plates.
The heat absorbing device is so positioned in relation to said reflecting surface and the curvature of the reflecting surface is so dimensioned that substantially the whole of the energy radiation entering through the spaces between the device and the side regions is reflected onto that part of the surface of the absorbing device not receiving direct energy radiation irrespective of the angle of incidence of the energy radiation on the reflector.
