Abstract: An apparatus and method for cooling the interior of an aviation crash helmet without incorporation of any mechanically moving components or fluids. The said system can cool or warm the head of the user through the use of thermoelectric cooling elements, solid state fans or electro-aerodynamic pumps, heat exchangers, and a customized ventilation system. None of the components in the present invention contain mechanically moving parts, fluids, or chemicals. The preferred embodiment was designed for aircraft crash helmets, but this invention can be incorporated into any existing crash helmet which can accommodate incorporating thermoelectric pumping modules and provide a steady power supply to the said components. This present invention can be incorporated into any existing crash helmet through customization of helmet inserts. It can also be incorporated into the design of new crash helmets which would facilitate the maximization of the efficiency of the said cooling system.
