Publication number: 20130340974Abstract: A cooling apparatus for a helmet is provided for cooling air in an interior space of a helmet to cool a wearer's head. The cooling apparatus maximizes the volume of air moving across an evaporator and minimizes the speed at which the air passes through cooling fins of the evaporator, thereby achieving air temperatures substantially below the outside ambient temperature. A narrow opening is provided between a first chamber of intake air and a second chamber which houses the evaporator, such that air passing through the narrow opening increases in velocity and pressure. Upon entering the second chamber which is a large open space, the highly pressurized and high velocity air immediately slows down and expands into the large second chamber, where it then passes across a large surface area of the evaporator and outward through a collection chamber and a blower to the inside of the helmet.Type: ApplicationFiled: June 24, 2013Publication date: December 26, 2013Inventor: Marc Christian Billen
