Thermal analysis of induction heating roll with heat pipes

Abstract

This paper deals with temperature performance of induction heating roll with or without heat pipes. The focus of this paper is to improve nonuniformity of the outer surface temperature of the roll by inserting heat pipes with very high thermal conductivity. In our work, the coupled magneto-thermal finite-element analysis considering skin effect is employed for evaluating the surface temperature. The predicted results are verified with experimental data.Index Terms-Coupled magneto-thermal finite-element analysis (FEA), heat pipe, induction heating, temperature performance.
