PURPOSE: An electric heater using high frequency induction heating is provided to prevent heat loss using radiant heat emitted to the outside of a glass tube. CONSTITUTION: An electric heater using high frequency induction heating comprises a heating element and a glass tube. The heating element is made of a steel plate, a silicon plate(30), and a stainless plate. The glass tube is made of thermal conductivity material. Induction coil is rolled with the back side of the glass tube. A heat film is formed on the rear surface of the induction coil and prevents heat dissipation. |
