Wide channel double-layer ventilating outer wall utilizing photovoltaic power generation

Abstract

The invention discloses a wide channel double-layer ventilating outer wall utilizing photovoltaic power generation, and belongs to the technical field of solar power generation building integration. The wide channel double-layer ventilating outer wall utilizing the photovoltaic power generation comprises a solid wall (6) and a solar cell panel (1) which is fixedly connected to the outer side of the solid wall (6) through a chemical anchor bolt (3). The wide channel double-layer ventilating outer wall utilizing the photovoltaic power generation is characterized in that a cavity (5) is reserved between the solid wall (6) and the solar cell panel (1). The width of the cavity (5) is controlled between 150mm and 200mm, an air outlet is formed in the upper portion of the cavity (5) and is provided with an air outlet valve (7), and an air inlet is formed in the lower portion of the cavity (5) and is provided with an air inlet valve (8). According to the BIPV method that the solar cell panel is combined with the solid outer wall, the cavity is reserved between the solar cell panel and the solid outer wall, the heat produced when the solar cell panel generates the electricity is brought away through the chimney effect, and the thermal radiation effect on building outer walls is reduced.

Description

technical field [0001] The invention belongs to the technical field of building-integrated solar power generation (BIPV for short), and particularly relates to a double-layer ventilated exterior wall that can reduce the temperature of the backplane of a solar photovoltaic module. Background technique [0002] Solar energy resources are abundant, and the use of solar energy is an effective way to alleviate energy shortages. Among them, building integrated solar power generation (BIPV for short) is the current mainstream trend of solar energy use. The solar panel and the building are effectively integrated, no additional space is required, and the energy generated is used locally, reducing energy consumption for transmission. There are many ways to combine BIPV, such as photovoltaic roof, photovoltaic exterior wall, photovoltaic curtain wall, photovoltaic sunshade components, etc. [0003] However, the thermal effect generated during the power generation process of solar pane...
