Abstract
Abstract This invention provides various personalized cooling systems in which heat relief is achieved by Peltier cooling. In one embodiment Peltier cells are attached to a garment with the cold plate of the Peltier cell in intimate thermal contact with the skin of the wearer of the garment. Heat generated by the Peltier cell is dissipated to the ambient from cooling fins. Heat pipes are used to conduct the heat to the fins, or to distribute the cooling across the skin.In another embodiment, personalized cooling in a closed environment such as a room, tent, or car is provided by selective Peltier cooling of garments or accessories in close thermal contact with the person to be cooled. The Peltier cells are powered from stationary power sources, where available, such as room electrical outlets or car batteries. In other embodiments the Peltier cells are powered by portable rechargeable batteries, or by solar cells carried by the person to be cooled. The rechargeable batteries are charged by portable solar cells.
