Solar energy collector - has heat transfer tubes integral with receptor screen and glass shutters and double-faced mirrors, maximising collecting power

摘要

Solar collector allows transport of a heat transfer fluid which has received the sun's radiations and transforms them into heat or motive energy. It comprises in its interior a self-deformable ensemble of receptor screen and heat transfer tubes made integral with one another by a number of bands cut out from the mass of the screen, and in front a set of glass shutters and double faced mirrors orientable in their vertical supports. Problems associated with ruptures at the weld points of the heat transfer tubes or the attachments of the whole to the case are avoided. The calorific power is greater than in the case of existing collectors in which the heat transfer tubes are sepd. from their reflective screens by bosses or adjunct to materials of which the coefft. of expansion is different.
