Energy-saving device

Technical Field

The utility model relates to a heat pipe type photovoltaic and photothermal integrated cogeneration device, belonging to the technical field of solar energy application; and relates to the technical field of energy conservation and consumption reduction of power plants, in particular to an energy-saving device.

Background

Solar energy is more and more widely regarded as clean energy, particularly, photovoltaic power generation is rapidly developed, but researches show that the conversion efficiency of a common solar panel is below 30%, about 70% of solar radiation received by the surface of a battery cannot be converted into electric energy, most of the solar radiation is converted into heat energy, and the photoelectric efficiency of the battery is reduced by about 0.4% when the temperature of the photovoltaic battery rises by 1 ℃, so that the temperature of the photovoltaic battery is increased, and the photoelectric conversion efficiency is reduced to some extent. If set up the cooling passageway at the battery back, take away the heat through the heat-absorbing medium, can improve the generating efficiency. If the absorbed heat is stored and utilized, the system can provide heat energy while performing photovoltaic power generation, which can be called a photovoltaic/thermal (PV/T) system. The solar photovoltaic photo-thermal integrated (PV/T) system simultaneously generates electric energy and heat energy by simultaneously using a Photovoltaic (PV) system and a heat collecting system, and although the integrated (PV/T) device can improve the photovoltaic power generation efficiency and simultaneously generate partial heat, the specific application of the cooperation work of the PV/T and a heat pump, a heat storage device and an electricity storage device is less at present, and most of the integrated (PV/T) system is in an experimental research stage.

In general, cogeneration converts chemical energy into electric energy and provides heat energy required by external users by burning coal, and since water has good heat transfer performance and high heat capacity, it is widely used by thermal power plants, and cogeneration uses heated water to realize power generation and external heat supply. The amount of coal used is reduced if the water temperature is increased by using other heat energy.

The water in the water pipe is increased in volume due to icing, so that the internal pressure is enhanced, and the water pipe is easy to burst.
