Heat preservation and heat collection photovoltaic cell panel heating system

Abstract

The invention relates to a heat preservation and heat collection photovoltaic cell panel heating system which is formed by connecting a heat collecting photovoltaic cell heat preservation panel and heat exchange equipment. The heat collecting photovoltaic cell heat preservation panel structurally comprises a heat preservation layer and a glass cover plate. Photovoltaic cell panels are arranged in the heat preservation layer, and back plates of the photovoltaic cell panels are closely attached to microchannel heat exchange flat pipes. The microchannel heat exchange flat pipes are arranged side by side. Channels of the microchannel heat exchange flat pipes communicate with an upper collecting pipe and a lower collecting pipe which are arranged in a heat preservation frame. The upper collecting pipe communicates with a water inlet pipe of the heat exchange equipment. The lower collecting pipe communicates with a water return pipe of the heat exchange equipment. According to the heat preservation and heat collection photovoltaic cell panel heating system, the heat preservation panel, the photovoltaic cell panels and a microchannel radiator are integrated, a heat preservation, power generation and heating integrated fabricated wallboard is formed, and mounted on an outer wall or a roof during outer wall construction, the appearance of the wallboard is the same as that of a common heat preservation and decoration board, the manner of mounting the wallboard on the building outer wall is also the same as that of the common heat preservation and decoration board, and the integrated seamless connection can be formed with a building.

Description

technical field [0001] The invention relates to a heat preservation and heat collection photovoltaic battery panel heating system, which belongs to the technical field of solar power generation, solar heat utilization and building integration. Background technique [0002] At present, ordinary photovoltaic panels directly collect solar radiation energy, and convert solar radiation energy into electrical energy output through the semiconductor PN junction in the panel. When the photovoltaic cell panel receives solar radiation and works normally, the surface temperature of the back plate can reach above 70°C, and at this time the temperature of the PN junction of the battery can exceed 100°C. [0003] Usually, as the temperature of the PN junction increases, the output power of the photovoltaic panel will decrease. Therefore, the cooling of photovoltaic panels has always been a key problem to be solved in the process of photovoltaic power generation. Someone once proposed a ...
