Heat-pipe type solar energy photoelectric and optothermal comprehensive utilization system

Abstract

The invention relates to a heat-pipe type solar energy photoelectric and optothermal comprehensive utilization system, which comprises a storage tank and a photovoltaic / hot water panel which are communicated with each other through a water channel, wherein the photovoltaic / hot water panel comprises heat pipes, photovoltaic cells and a heat-conductive metal plate; the photovoltaic cells are connected in series into a strip and uniformly distributed on the upper surface of the heat-conductive metal plate; a gap is reserved between two adjacent rows of the photovoltaic cells; evaporation sections of the heat pipes are uniformly distributed on the rearward of the heat-conductive metal plate; an evaporation section of each heat pipe is positioned on the gap between the two adjacent rows of the photovoltaic cells; a heat-insulating layer is also arranged on the rearward of the heat-conductive metal plate; the heat pipes are enveloped by the heat-insulating layer; copper sleeves are uniformly distributed on a heat-collecting flow channel pipe and are perpendicular to the heat-collecting flow channel pipe; and a condensation section of each heat pipe is inserted into a copper sleeve. The heat-pipe type solar energy photoelectric and optothermal comprehensive utilization system has the advantages that the solar energy comprehensive utilization efficiency of the system is greatly improved; as the system can be used in cold regions with high latitudes, the territorial scope of the use of the system is enlarged; and as the system achieves the indirect heat conducting through the heat pipes, the corrosion degree of running water on solar panel cores is greatly reduced and the service life of the solar panel cores is prolonged.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and in particular relates to a heat pipe-type solar photoelectric, photothermal comprehensive utilization system. Background technique [0002] At present, my country has launched a low-carbon economic strategic economic policy to change the situation that my country's low energy utilization efficiency and the excessive use of coal and other fossil energy have led to more severe energy problems and increasingly serious environmental damage in my country. Solar energy is an important alternative to traditional energy because of its renewable and environmentally friendly advantages. At present, the utilization methods of solar energy mainly include photothermal conversion utilization and photoelectric conversion utilization. [0003] A single photoelectric or photothermal system can only get one kind of benefit. The solar photovoltaic / hot water (PV / T) system belongs to a solar ph...
