Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 , the solar panels 1 are spliced ​​into a square array and installed on the sunny facade of the building, usually the south facade, west facade or east facade.

[0025] Such as figure 2 , the solid wall 6 is made up of a concrete structure 6-1 pasted with a class A fireproof and thermal insulation material 6-2.

[0026] Such as image 3 , the solar panel 1 is fixed in the concrete structure 6-1 through the angle steel 2.

[0027] Such as Figure 4 , the solar panel 1 and the exterior wall concrete structure 6-1 are connected and fixed by the chemical anchor 3, which is set in the concrete load-bearing member and avoids the position of the steel bar. The effective anchoring depth of the chemical anchor is not less than 8d (eight times the diameter ).

[0028] Such as Figure 4 , There is a cavity 5 between the out...

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...
