Flat-plate solar water heater capable of generating power

Abstract

The invention discloses a flat-plate solar water heater capable of generating power, which comprises a water tank and a flat-plate heat collector arranged at the lower part of the water tank, wherein the flat-plate heat collector comprises a semi-closed heat insulation framework, metal pipes, refrigerating pieces and finned pipes, and a transparent glass plate is arranged on the semi-closed heat insulation framework; a plurality of communicated metal pipes are arranged in the closed space of the heat insulation framework, and the finned pipes are arranged above evaporation sections of the metal pipes; and the refrigerating pieces are positioned between the metal pipes and the finned pipes, and two ends of the refrigerating pieces are led out by leads to be connected with an external electric power storage device. The solar water heater capable of generating power can not only convert solar energy into heat energy to heat water, but also convert part of heat energy which is not stored timely into electric energy so as to supply additional power to users, the service efficiency of solar energy is improved, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a flat solar water heater capable of generating electricity. Background technique [0002] Solar water heaters are more and more widely used in daily life due to their environmental protection, energy saving, convenience and practicality. Solar water heaters are generally divided into flat plate solar water heaters and vacuum tube solar water heaters. The solar water heaters currently on the market are basically a light-to-heat converter, which directly uses heat-absorbing tubes or vacuum tubes to convert the absorbed solar energy into heat for people to use. In summer, the continuous and sufficient solar energy makes hot water often reach Boiling, the amount of heat generated becomes larger, the heat energy cannot be fully utilized, and most of the heat energy is lost in vain. The most direct way to convert solar energy into electrical energy is to use solar cells. However, solar cell p...

The solar water heaters currently on the market are basically a light-to-heat converter, which directly uses heat-absorbing tubes or vacuum tubes to convert the absorbed solar energy into heat for people to use. In summer, the continuous and sufficient solar energy makes hot water often reach Boiling, the amount of heat generated becomes larger, the heat energy cannot be fully utilized, and most of the heat energy is lost in vain.

The most direct way to convert solar energy into electrical energy is to use solar cells. However, solar cell power generation technology needs to cooperate with control circuits. The energy conversion rate is low, the cost is high, and the cost performance is low. Consumers are difficult to accept and can only be limited to developed areas. sexual use
