Cooling fan structure, constant pressure characteristic of airflow, and thermal protection
Overheating devices can cause a number of problems, including shortening of the product life, parts being worn out quickly, malfunctions, and other safety risks. Cooling fans and blowers are essential for use in hot environments. To avoid these problems The appropriate cooling device must be selected for these systems.
Cooling fan specifications vary according to the ventilation system. The following describes the structures of the axial fan, crossflow fans and blower fans as well as their constant pressure-flow characteristics. It also mentions overheating protection (Thermal Protector) by means of an alarm when the speed falls below a certain point.
