The helmet has an Integral Thermoelectric/Pelzer Device with attached External Heat sink and an Internal Cold sink. Small quiet internal fans or Internal Blower force air over the cold sink into internal Duct work to cool the riders head as the Heat Sink draws off hot air outside. The Helmet plugs into a standard 12V power supply. It has a reversible plug attachment that allows reverse 12V polarity. The Integral Thermoelectric/Pelzer Device then runs in reverse, this allows the helmet to be in Heat mode. Everything, heat, cooling, fan/blower speed is controlled electronically.
MOTORCYCLE HELMET COOLING DEVICE: A motorcycle
