A new flat solar collector features a heat-absorbing surface that equals the heat-transferring surface, resulting in high-heat performance and efficiency. There is no mediatory unit between the heat-transferring surface of the absorber and the heating agent. This means no galvanic corrosion, which would work as insulation. The main unit of this system is a hot-pressed and alloyed aluminum plate. The plate has shallow channels for liquid that run parallel and are connected to each other. The tips of the plate lead into the distributing or collecting pipes supplying them with a capacity of 1.7 liters, and the two necessary inputs and outputs.
This design is made from homogenous alloyed aluminum. It has good heat conductivity (235 W/m°C) and is weatherproof, non-corrosive, light, and easy to assemble. Surface treatment used on the alloyed aluminum plate is unglazed black elox coating. Special alloyed aluminum frame profiles are used for the collector house, reducing the mass.
