Solar photovoltaic and photo-thermal composite heat collection device

Abstract

The application discloses a solar photovoltaic and photo-thermal composite heat collection device, wherein a heat collection panel is arranged under a photovoltaic panel; the heat collection panel andthe photovoltaic panel are adhered by a thermal dissolution method; the heat collection panel is an evaporation zone of a separated panel heat collection pipe and is constituted through combination of two aluminum plates; a semi-circular micro-channel gravity assisted heat pipe structure is processed by a gas expansion method; a heat storage tank is installed above the heat collection panel, is equivalent to a condensation section and has a horizontal three-layer casing structure, and a small cylinder is formed in the center for flowing of working medium steam; a cylinder outside a steam cylinder is filled with water as a heat storage material, and the heat storage material is used for heat exchange of the steam in the steam cylinder; and the outmost cylinder of the casing is filled withparaffin as a supplementary heat storage materials, and the outer surface of the steam cylinder is closely winded with a copper spiral pipe used as a cold water pipe. In this way, efficiency of heat collection and heat storage is high; an extra power pump is not needed during system running; the heat exchange working medium can flow by a tap water pipe system or a high water tank, so energy consumption is reduced and heat exchange effects can be improved significantly; and commercial application prospect is broad.

Description

technical field

[0001] The invention belongs to the new energy technology field of using solar energy for photovoltaic power generation and waste heat collection. Specifically, it relates to the design of a composite heat collecting device composed of a photovoltaic power generation board-separated flat heat pipe type heat collecting plate and a heat storage box with paraffin heat storage material. Background technique

[0002] The consumption of traditional energy such as coal, oil, and natural gas has exacerbated the world's environmental problems, and with the reduction of the total amount of non-renewable energy such as coal, oil, and natural gas, energy issues have gradually become a bottleneck restricting the development of the international society and economy. The use of renewable energy to replace traditional energy has undoubtedly become the best way to solve these problems. Renewable energy includes wind energy, water energy, geothermal energy, tidal energy and s...
