<p>A low-frequency electromagnetic induction heater which applies a low voltage-high current performance transformer is disclosed. In the present heater, any space or vacancies between an induction coil (2) and a metal heating pipe (3) is excluded. This invention provides a high performance heater with the small temperature difference between the heating part and the material to be heated, high thermal efficiency, high reliability, high durability, and steady operation during a long period.</p> |
