Ventilation structure for BIPV modules

A novel ventilation structure for building integrated photovoltaic (BIPV) modules, comprising photovoltaic modules matched with a building wall, an air inlet passage, and an air outlet chimney, wherein:

• a back of the photovoltaic modules is installed on a facade of the building wall in parallel through a plurality of steel columns;
• the photovoltaic modules and the building wall cooperatively define a ventilation gap, wherein the air inlet passage is disposed out of the ventilation gap and mounted to a bottom of the ventilation gap, the air outlet chimney is disposed out of the ventilation gap and mounted to a top of the ventilation gap, and the air inlet passage, the ventilation gap, and the air outlet chimney are in communication with one another to enable an airflow to flow through the air inlet passage, the ventilation gap, and the air outlet chimney in sequence;
• and
• a length L of a top surface of the air inlet passage is 0.5 m to 2 m, a height H of an opening of the air inlet passage is 0.2 m to 0.8 m, a width of the ventilation gap is less than 0.08 m, and a ratio of the height of the opening of the air inlet passage to the width of the ventilation gap is 2.5 to 10.
