Description

Technical Field

[0002] With the trend of lightweight photovoltaic modules, thinner tempered glass is required, and the flatness requirements of photovoltaic glass are becoming increasingly stringent. When the glass is heated in the deep processing tempering furnace, the airflow and temperature distribution in the furnace are uneven, which will cause the glass to have problems such as large flatness and corrugated bends.

[0003] In addition, the gas balance of the existing glass tempering furnace is achieved by blowing compressed air directly into the furnace body, which can only adjust the air flow and the air pressure balance in the furnace, but cannot achieve the control of uniform temperature distribution in the furnace. Moreover, blowing unheated compressed air into the furnace will cause a large amount of heat loss in the furnace, thereby increasing the energy consumption of the equipment.
