FIELD: power engineering.SUBSTANCE: solar collector for water heating consists of two welded to each other metal sheets, top and bottom stamped with corrugations or with round dents for point welding of sheets to each other, and four threaded hollow bars, welded to the bottom sheet, that allows to pump through slit-like cavities between sheets the sufficient amount of water, for connection with pipelines in the hot water supply system. The sheets are point welded to each other along contour and corrugations or round dents, and the top sheet along edges has wave profiles; that provides a possibility to use each collector as a roofing module, meanwhile the screen (top sheet) of each collector is coated with a selective coating.EFFECT: given invention will allow to decrease expenses for purchase of roofing material, and also will allow to erect modular solar collectors on building roofs.4 dwg |
