Induction heaters are a type of non-contact heating that uses electromagnetic induction to heat electrically conductive materials. The induction heater consists of an induction coil that creates a rapidly changing magnetic field. When the material to be heated is placed in the magnetic field, eddy currents are induced in the material. These eddy currents cause the material to heat up by Joule heating.
Induction heaters are used in a variety of applications, including:
- Metalworking: Induction heaters are used to heat metal for a variety of purposes, including welding, brazing, soldering, and hardening.
- Plastics processing: Induction heaters are used to heat plastics for a variety of purposes, including forming, welding, and curing.
- Food processing: Induction heaters are used to heat food for a variety of purposes, including cooking, pasteurisation, and sterilisation.
- Medical applications: Induction heaters are used in medical applications, such as cancer treatment and hyperthermia.
Induction heaters offer a number of advantages over traditional heating methods, including:
As a result of these advantages, induction heaters are becoming increasingly popular in a variety of industries.
