Experimental Analysis of the Cooling of a Motorcycle Helmet by Using Phase Change Material with Forced Convection

This paper presents an experimental analysis of the cooling of a motorcycle helmet with the help of phase change material (PCM) and using air flow circulation through the surface of the phase change material. The heat produced by the head of the wearer is absorbed and stored by phase change material and stored heat is thrown out with the help of air circulation in the helmet. In this PCM is placed between the head of the wearer and helmet metal shell. Thus the heat produced by head of the wearer and heat in the helmet metal shell due to atmospheric high temperature and expanded polystyrene foam (EPF) will be absorbed by the PCM but to increase the duration of working of the PCM, here we implement the method of forced convection by the installing two fan which removed the inside heat of the helmet and extend the working time of the PCM. This maintains the wearer head temperature nearly melting point of PCM temperature and protects the wearer head from discomfort and hot environment. If only PCM will be used then the cooling is achieved for few hours only when the PCM is completely melted.
