Title (EN) SOLAR RADIATION COLLECTOR
(FR) CAPTEUR DE RAYONNEMENT SOLAIRE
Abstract: front page image
(EN)Solar radiation collector of the plane and fixed type. It employs a heat absorbing panel of which the active surface is formed by heat conductive thin plate (2) deeply rippled with ripplings of trapezoidal section and coated with smoky black. A second plate (3) preferably flat is welded to the first one and forms small channels where the heat carrier fluid circulates vertically. Hence, losses due to radiation emission and reflection are reduced and other losses due to radiation emission are avoided because of the absence of spots on the panel having a higher temperature than that of heat carrier fluid. The absorbing panel is inserted into a light coffer containing a block of insulating rigid foam (5) and is protected on the front by a thin, light transparent plate (6); the cost, the difficulty of transportation and the weight of the complete solar radiation collector are thus considerably reduced while the thermal efficiency is increased.
(FR)Capteur de rayonnement solaire du type plan et fixe. Il utilise un panneau absorbeur de chaleur dont la surface active est formee par une plaque mince (2) thermiquement conductrice profondement ondulee suivant des ondulations a section trapezoidale et recouverte de noir de fumee. Une seconde plaque (3) de preference plane est soudee a la premiere et forme de petits canaux que le fluide caloporteur parcourt verticalement. On reduit ainsi les pertes par emission de rayonnement et par reflexion et on evite d"autres pertes par emission de rayonnement grace a l"absence de points du panneau a une temperature plus elevee que celle du fluide caloporteur. Le panneau absorbeur est insere dans un caisson leger contenant un bloc de mousse rigide isolante (5) et est protege a l"avant par une plaque transparente mince et legere (6); le cout, la difficulte de transport et le poids du capteur de rayonnement solaire complet sont ainsi notablement re et le rendement thermique est augmente.
