The invention relates to a sensor equipped with a member which selectively absorbs solar energy. This member is constituted by two sheets of a rigid material serving as a support for a layer of material which is sensitive to solar radiation, the two sheets being joined together over their entire length and folded in such a way that the member has a lozenge-shaped cross-section, which can be applied in four contact zones against a tubular wall and can remain in intimate and permanent contact with the latter, no matter what the temperature variations undergone by the assembly.

Solar sensor equipped with solar energy absorbing member and panel

A device for collecting solar energy and conveying it to a zone to be heated. It comprises a tube in two parts, the first part (evaporator) being surrounded by a vacuum and being covered with a heat absorbing material and exposed to the solar radiation. The tube contains a fluid which vaporized in the first part and absorbs heat and condenses in the second part and gives up the previously-stored heat. The fluid in the liquid phase is returned to the first part by a capillary system.
