Abstract


In developing heaters typically and induction heater in specific temperature limits can be a key issue disturbing the efficiency of the overall policy. Since typical loading of induction heater is commonly costly. The estimation of temperature rise by tools of mathematical modelling becomes a lot of and a lot of  necessary. Excepting for providing an additional correct illustration of the matter. The projected model might in addition cut back computing prices. The paper develops a two dimensional steady state thermal model in polar co-ordinates by means of finite element formulation and arch shaped components. A temperature time methodology is utilized to calculate the distribution of loss in various elements of the induction heater. Overwhelming these loss distributions as input for finite element analysis. Additional precise temperature distributions are obtained. The projected model is applied to predict the temperature rise within the coil of the induction heater 3200 W totally encircled fan-cooled induction heater. The temperature distribution has been determined considering convection from the outer air gap surface and circular finish surface for each entirely encircled and semi encircled structures.
