Fabrication and Analysis of Motorbike Helmet Using PCM for Temperature Control

It is estimated that 40 - 50% of the total heat produced within the body is released through the head. This dissipated heat from our head gets trapped inside the helmet resulting in increased internal temperature along with the addition of external heat from the surrounding, making it uncomfortable for the user. This work discloses on the designing and fabrication of a cooling system implemented in a motorbike helmet with the use of PCM (Phase Change Material) and mechanically constructed Fins fixed onto the shell surface, to prolong the thermal comfort period compared to a normal helmet. The PCM material is packed in pouches and placed between the Expanded Polystyrene Styrofoam (EPS) and Outer Shell of the helmet. As heat is generated inside the helmet, the PCM absorbs the heat, which is then transferred to the fins. Fins are provided to help in a faster heat transfer rate from the helmet to the surrounding. This hence helps in maintaining the internal temperature for the user by preventing the excess heat from accumulating inside the helmet and thereby removing a major cause of discomfort to the rider.
