INDUCTION HEATING TYPE HEATER

摘要

An induction heater is disclosed. According to one aspect of the present invention, an induction heater is provided to be inserted into a hollow of a body to be heated to induction heat the body to be heated. The induction heater includes: a first coil formed to extend in a longitudinal direction from a first terminal at one end; a first coil formed to extend in a longitudinal direction from a second terminal at one end, and arranged to adjacent to the first coil; and a connecting portion configured to connect the other end of the first coil with the other end of the second coil. The first coil, the second coil and the connecting portion are connected to one another to form a flow path of a refrigerant from the first terminal to the second terminal, and are made of an electrical conductor. The first and second coils are arranged at a first interval in a partial section in the longitudinal direction to form a non-heating section, and are arranged at a second interval greater than the first interval in another partial section in the longitudinal direction to form a heating section.
