FIELD: engineering of sun-powered heating plants, possible use for heating, for instance, providing hot water to inhabited and industrial structures and other objects, and also for other technological goals. ^ SUBSTANCE: collector-receiver has body, absorber, made with mirroring absorbing surface in form of corrugated plate with curvilinear profile, transparent wall and heat exchanger. Transparent wall abuts on combs of absorber, space between which and wall is vacuumized. End walls of body are connected to end edges of absorber and sheet of transparent wall, and heat exchanger is formed by back surface of absorber and body walls. Transparent wall has clarifying layers one the side of absorber, decreasing reflection of beams falling from outside from inner surface of wall with maintained full reflection from external surface of wall from beams, reflected by absorber towards wall, while to combs and sharp bends of absorber recesses black absorbing cover is applied. ^ EFFECT: realization of collector with increased efficiency, absorbing both direct sun emission and dissipated or reflected emission and compatible with any type of heat carrier. ^ 3 dwg |
