Temperature-adjusting hat

Abstract

A temperature-adjusting hat, having a hat having an inside for accommodating a head and an outside, a thermoelectric couple having a first side and a second side having a temperature differential between the first and second sides, and wherein the first side is positioned near the inside of the hat, a power source connected to the thermoelectric couple, and one or more heat pipes connected to the second side, extending over the outside of the hat, wherein the one or more heat pipes has a constant temperature along a length. The hat may have a heat wicking layer in communication with the one or more heat pipes, configured to distribute a temperature from the heat pipes across the outside of the hat. The heat-wicking layer may be graphene or pyrolitic graphite. The heat-wicking layer may be copper sheeting or aluminum, and the first side is positioned to contact a forehead.
