Скачать или смотреть How Does a Hair Dryer Work? Inside the Heat & High-Speed Airflow Engineering

Ever wondered what’s really happening inside your hair dryer every time you switch it on?
In this Knowledge Hub deep dive, we break down exactly how hair dryers work, how they convert electricity into intense heat and high-speed airflow using nichrome heating coils, universal motors, and clever airflow design. If you’ve ever asked “How does a hair dryer work?” this video takes you far beyond the basic answer and shows you the real engineering inside.

A modern hair dryer is a compact thermodynamic machine. Electrical energy flows into a coiled nichrome heating element, which heats up through electrical resistance. A high-RPM universal motor drives an axial fan that pulls in cool room air, forces it across the red-hot heating coil, and blasts it out as focused, hot, high-velocity air. Along the way, the dryer uses forced convection, ceramic or tourmaline coatings, ionic technology, and safety cut-offs to control temperature, protect your hair, and prevent overheating.

In this video, we unpack the full system: the electric circuit, the heating element, the motor and fan, airflow channels, temperature controls, and safety systems, all explained in clear, simple language with solid engineering detail. Perfect for students, engineering enthusiasts, or anyone who just loves understanding how everyday technology really works.
