Solar water heater manufacturing materials
Flat panel collector in the development of the solar energy industry is unstoppable, not rely on some manufacturers can be strangled misleading. Now many designers of the water supply and drainage designers have been aware of this problem.All glass evacuated solar collector tubes are generally made of high borosilicate 3.3 hard glass, vacuum sputtering process. It can be divided into aluminum nitrogen single target coating process and copper, aluminum, stainless steel three target coating process.
At present, China's market is the universal glass solar heat collection vacuum tube. The structure is divided into the outer tube, inner tube, selective absorbing coating, getter, stainless steel clip, vacuum jacketed etc.. The collector of foreign mature are flat plate collector, flat plate collector has the advantages of long service life, high stability, Recyclable advantages, but because of serious ATM collector cost slightly higher, a lot of domestic production of low price flat collector performance is not good, so it is the main performance of domestic solar energy flow manufacturers distorted flat plate collector.
The utility model relates to a solar water heater, which is composed of a vacuum heat collecting pipe, a thermal insulation water tank, a bracket and a connecting pipe. The collector: the heat collecting component in the system. The utility model is equivalent to an electric heating tube in an electric water heater. And electric water heater, gas water heater is different, the solar collector is the use of solar radiation heat, so the heating time can only be in the sun
