Conduction Heat Study of Different Coil Design of Electric Iron

Abstract

Electric iron pulls energy from the mains supply and heats a coil within then the heat is transferred to the bottom plate through conduction process which is placed against the wrinkled garment. The problem of existing dry iron is the heating element continues to get hotter until the power source is continuously drawn from electricity, do not heat up sufficiently, needed a continual charge from its platform every few minutes for prolonged use, cannot be heat up rapidly and fast aging problem. Hence, it is necessary to run the finite element analysis on electric iron part model. The simulation focusses on thermal analysis as it can ease the study related to the heat path and thermal design of simulated product that can be used to improve the efficiency of existing product. The 3D part models of electric iron and five different type of heating coil were designed. Rheological data and important properties of the electric irons were imported as a parameter database in the software to create the meshing on the model. The input parameters are heat power, heat flux and convection while the variable for the simulation process are design of heating coil, power supply, thickness of heating coil and material of soleplate. Based on the simulated part model, the features recommended is design coil 4 with power supply 1900W, coil thickness 0.0015m and ceramic soleplate as these variables has highest temperature and shortest steady state time.
