太阳能原理（Solar energy principle） 1, working principle and structure composition Split bearing balcony wall type solar water heater solar collector installed on the outer side of the balcony, the hot water storage tank is installed on the balcony inside or indoor, the electric heating device is arranged in the water tank, so that you can use solar water heaters and electric water heaters organically, not only meet the installation requirements of high-rise buildings, but also can ensure all-weather hot water supply. For the solar water heater, the structural parts of the solar water heater are mainly composed of 6 parts, namely, a solar water heater and a solar water heater: Solar collector. It mainly completes the reception and conversion of solar energy from light energy to thermal energy. The solar collectors used in the balcony wall hanging are mainly flat type, U type, vacuum tube type and heat pipe, vacuum tube type three kinds. Flat plate solar collectors are widely used in Europe and America, and the proportion of flat heat collectors in our country is low because of the large-scale development of all glass vacuum tubes. The utility model has the advantages of high thermal efficiency, good pressure bearing, no hidden danger of overheating, and the like, and is a very ideal solar energy collector combined with building. U vacuum tube type solar collector is inserted into a U tube in all glass vacuum tube, and there is a metal fin which is in close contact with U and glass vacuum tube, as the heat transfer between the two. The vacuum tube has two forms, one is the selective absorbing coating on a glass tube, vacuum tube heat absorbing fin through the heat transfer to the U type pipe in the medium, the other is a metal fin type U tube in selective absorption coating on the U tube directly to medium heat. Heat pipe type vacuum tube solar collector heat pipe installed in all glass vacuum tube, hot metal fin close contact tube, directly by the fin endothermic, and the
