Novel ventilation structure for building integrated photovoltaics (BIPV) module
The invention relates to a new ventilation structure for a building integrated photovoltaics (BIPV) module, which comprises a photovoltaic module matched with a building wall body, the back surface of the photovoltaic module is installed on the outer vertical surface of the building wall body in parallel through a plurality of steel columns, and a ventilation gap is formed between the photovoltaic module and the building wall body. An air inlet channel used for forming a contraction air inlet is transversely inserted into the bottom of the ventilation gap, and an exhaust chimney serving as an air outlet is longitudinally inserted into the top of the ventilation gap. According to the invention, the air duct between the photovoltaic module and the building wall is modified in a simple way, so that natural convection in the ventilation gap can be accelerated to a high wind speed level similar to the condition of forced convection, but no mechanical fan device is needed, and the ventilation cooling of the BIPV module can be enhanced under the condition that the power consumption is not increased; in addition, the improved ventilation structure can be easily achieved, a large amount of installation work is not needed, and the related fixing cost is far lower than that of modification of a single solar cell panel.
本发明涉及一种用于BIPV模块的新通风结构，包括与建筑物墙体相适配的光伏组件，所述光伏组件的背面通过多个钢柱平行安装于所述建筑物墙体的外立面上，所述光伏组件与建筑物墙体之间形成有通风间隙，所述通风间隙的底部横向插设有用于构成收缩进风口的进气通道，其顶部纵向插设有作为出风口的排气烟囱。本发明以一种简单的方式修改了光伏组件和建筑物墙体之间的风道，这样通风间隙中的自然对流可以被加速到与强制对流的情况类似的高风速水平，但无需任何机械风扇装置，可以在不增加电力消耗的情况下增强BIPV模块的通风冷却；此外，本发明改进的通风结构可以很容易地实现，而无需大量的安装工作，相关的固定成本也远低于单个太阳能电池板的修改。
