Solar thermal collector specially designed for fabricated building

Abstract

The invention relates to the technical field of solar water heaters, in particular to a solar thermal collector specially designed for a fabricated building. A heat storage medium is heated through exposure of the sun to a glass vacuum pipe, and when hot water needs to be used, the water is guided into a spiral heat exchange coil through a water inlet pipe for heat exchange and then enters a hot water storage tank. The solar water heater is discharged for used through a drainage pipe, and is high in convenience; and meanwhile, the inclination angle of the glass vacuum pipe can be finely adjusted through a screw pipe and a screw rod, so that the utilization effect of the glass vacuum pipe on solar energy is improved. The solar thermal collector comprises a heat storage tank, the heat storage medium, a bottom pipe support, the glass vacuum pipe, the water inlet pipe, the spiral heat exchange coil, the drainage pipe, a heat storage water tank exhaust valve, the hot water storage tank, a heat storage medium tank exhaust valve, a heat storage water tank blow-down valve, a heat storage medium tank blow-down valve, a base, an underframe, a rotating shaft, fixing seats, supporting columns,the screw pipe, the screw rod, a hinge seat, a bracket, connecting rods, a bracket, an expansion box, a communicating pipe and an oil filling pipe. An inner cavity is formed in the heat storage tank.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a solar collector specially designed for prefabricated buildings. Background technique [0002] As we all know, solar energy, wind energy, and geothermal energy are three renewable energy sources that have been recognized by mankind as clean energy for future economic development. Traditional solar water heaters directly heat water through solar vacuum glass tubes, thereby utilizing solar energy. Water heaters have many disadvantages. Most traditional water heaters are only used in summer or spring and autumn when the temperature is high. When used in a low temperature environment, the water in the glass vacuum tube is easy to freeze and cause the glass tube to burst. And the traditional water heater Solar water heaters are difficult to heat water quickly, have low efficiency, cannot use a large amount of hot water, and have relatively large limitations.
