Thermal Analysis of Inductive Coils Array against Cylindrical Material Steel for Induction Heating Applications

摘要

This paper presented the heating of inductive coil which is 3 elements array. The induction heating coil improve the variations heating that it is increased the system efficiency. By means of the inductive coil has the diameter of 2, 3 and 4 cm and divide the coil as 2 types. There are the inverses and reverse inductive coil arrays, with heating test by cylindrical steel material. Then, this paper considers the heating efficiency simulation of 2 types by CST EM studio 2009. In addition, the experimental of the inductor heating is use the full bridge inverter circuit, the power of 200 W at 28 kHz resonant frequency. Moreover, the distance between coils is coincided of simulation and experimental results, the inverse type at the diameter of 2 cm can be provide the maximum heater.
