HOT BLAST GENERATOR BY INDUCTION HEATING

摘要

PROBLEM TO BE SOLVED: To provide a hot blast generator which can remove heat generated in an induction coil by a compact constitution. SOLUTION: This device is constituted so that cooling water pipes 13 made of resin are wound between electric wires 1a of neighbored induction coils to be wound around the outer peripheral face of a cylindrical heater case 6, and that generated heat by the electric wires 1a and heat-transferred heat via the heater case 6 are made to be cooled by the cooling water to circulate in the cooling water pipes 13.
