Abstract

The invention discloses a narrow-channel double-layer ventilation external wall utilizing photovoltaic power generation, and belongs to the technical field of solar power generation BIPV (building integrated photovoltaics). The external wall comprises a solid wall (6) and a solar cell panel (1) which is fixedly connected with the outer side of the solid wall (6) through a chemical anchor bolt (3), wherein a cavity (5) is reserved between the solid wall (6) and the solar cell panel (1); an air outlet is formed above the cavity (5) and is provided with an air outlet valve (7); and an air inlet is formed below the cavity (5) and is provided with an air inlet valve (8). Aiming at the BIPV manner combining the solar cell panel and the external solid wall, one cavity is reserved between the solar cell panel and the external solid wall, and the heat yield in a power generation process of the solar cell panel is taken away through forced ventilation of a direct current fan, so that the heat radiation effect on external walls of buildings is reduced.

Description

technical field

[0001] The invention belongs to the technical field of building integrated solar power generation (BIPV for short), and in particular relates to a double-layer ventilated exterior wall which uses forced ventilation to reduce the temperature of the backboard 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 genera...
