AI Technical Summary
When existing electric heating air curtains are in use, the fan draws cold air into the air duct, but it cannot guide the cold air to flow over a large area on the surface of the heating wires. As a result, some heating wires fail to come into contact with the cold air, leading to poor heating effect.
The system employs an air guiding mechanism, including components such as a rotating shaft, guide plate, double-groove pulley, and belt. Driven by a motor, it ensures that cold air is evenly distributed on the surface of the heating wire, guaranteeing that every part of the heating wire can come into contact with the cold air and improving the heating effect.
This allows for large-area contact between cold air and the surface of the heating wire, improving the heating effect and making the heating effect of the heating wire more uniform and efficient.
