FIELD: heating.SUBSTANCE: solar collector includes two side profiles, each of which is made in the form of a vertical wall provided on its ends with bulges with slots perpendicular to the wall, a transparent enclosure made from glass fixed on lateral sides in upper slots of side profiles, a rear wall fixed on lateral sides in lower slots of side profiles, an absorber with heat carrier flow tubes, which is located between glass and rear wall, and heat insulation arranged between the absorber and rear wall. Cavities of side profiles between slots are filled with side heat insulation. Collector is provided with transparent heat insulation of capillary type, two end "?"-shaped profiles and two end cover plates. In addition, glass is fixed on end surfaces between end cover plates and upper flanges of end "?"-shaped profiles. In addition, rear wall is fixed on end surfaces between end cover plates and lower flanges of end "?"-shaped profiles. Cavities of end "?"-shaped profiles between flanges are filled with end heat insulation. Upper slots of side profiles have width that exceeds thickness of glass fixed in them, and upper flanges of upper slots are provided with a projection on the end.EFFECT: simpler manufacture of a solar collector and improvement of its reliability.5 cl, 6 dwg |
