The invention relates to a flat, reversible solar collector comprising protection against damage caused by freezing, incrustation and problems associated with the use of hard water and insulation that deteriorates under humid conditions. For damage caused by freezing, the invention comprises flexible plastic tubing sealed at the ends thereof or along the entire length of same and positioned within the two heads and the absorber is built with flexible crossbars, allowing the increase in the volume of water when it freezes to be attenuated by said elements, preventing the fracturing of the tubing. In order to avoid problems of obstruction in the conduits caused by hard water (with high salt contents), the collector is formed by a large quantity of crossbar, using materials that have a high resistance to the adherence of salts compared with metal tubing. In order to prevent the degradation of the plastic absorber in high temperatures and as a result of the materials used to construct the collector, vents have been added to dissipate the heat. Said collector is advantageous in that it is reversible given that the cover and the rear are built from the same material. |
