P -N Junction Cooling Helmet Using Peltier Effect

Human life is so precious and valuable, that it should not be compromised under any cost. The concern over the safety of Motorcyclist drivers has pushed for the invention of the equipment that can save lives. According to Statistics from the Insurance Institute for Highway Safety (2010),it is mentioned that nearly 70% of mortality in road accident occurred due to head injury. It is not that people are very negligent about their lives on road, but that they experience dozens of discomforts by wearing helmet. The most common discomfort is that, heavy sweat occurs due to excessive heat formation. This project deals with the development of cooling system for biker’s helmet using thermoelectric technology using Peltier module. This system consists mainly of a heat sink, aluminium passageway and Peltier coil. The prototype is fabricated and mounted onto biker’s head. Experiments are conducted on the prototype to analyze the performance of the cooling system during different intervals of time.
