What is the difference between a fan that pumps hot air and one that pumps cold air?


the role of different: hot wind gear is mainly used to dry hair, while the cold wind gear is mainly used for styling.

1, the role of different: hot wind gear is mainly used to dry hair, while the cold wind gear is mainly used for styling.

2, hair softness is different: the use of cold air dry hair, generally to soft a little. Drying hair with hot air is equivalent to drying the hair, the moisture on the hair is all evaporated, it will look very frizzy and dry.

A hair dryer is a combination of a set of electric filaments and a small, high speed fan. When energized, the electric filaments generate heat, and the wind from the fan passes through the electric filaments and becomes hot air. If only the small fan rotates and the filament is not hot, then the wind blown is just wind and not hot. The wind blown out by a hair dryer is dry wind, and if it is used for too long, it can easily cause moisture loss and heat damage. The secret to minimizing the damage is to use a towel to pat dry the moisture on your hair first, and gently comb your hair with your hands, and then use a hair dryer.

Hair dryers rely directly on an electric motor to drive the rotor to drive the wind blades to rotate, when the wind blades rotate, the air is sucked in from the air inlet, and the resulting centrifugal airflow is then blown out from the front nozzle of the air blower. When the air passes through, if the heating wire on the heating support installed in the nozzle has been energized to become hot, it is blown out of the hot air, if the selector switch does not make the heating wire energized to become hot, it is blown out of the cold air. Hair dryer is this to realize the purpose of drying and shaping.
