Abstract
A heating element includes a plurality of folded surfaces which can be resistively heating using electrical current. The heating element can advantageously function both as a heating source and a heat transfer device, as the need for separate fins or other heat dissipation members is eliminated. In some embodiments, the heating element can be included in a fluid heating system. The fluid heating system can include a fluid transfer device configured to deliver a volume or ambient air or other fluid through the heating element. As air moves past the heated folded surface of the heating element, it is heated. Heated air can then be discharged to one or more desired locations.
