Abstract

A heater comprising: (a) a film; (b) one or more coverings that extends along one or more sides of the film; and (c) one or more power application portions that apply power to the film so that the film heats up; wherein the film is a graphite film.

Description

technical field [0001] The present teachings relate generally to film heaters, and preferably to synthetic graphite film heaters and methods of making the same. Background technique [0002] The present teachings aim to provide an improved heater, and more preferably, an improved heater for use in a vehicle. Typically, the heater includes lines formed in a pattern. When electricity is applied to the wire, the wire generates heat. It is also possible to place the wire in the carbonaceous material so that when the wire is heated, the heat diffuses into the carbonaceous material, thereby heating a larger area. However, achieving uniform heating in these devices may not always be possible and hot spots may occur around the heating wire. Also, if the heater wire breaks, the heater may stop heating. The heater may also include electrodes connected by a positive temperature coefficient material such that electricity is conducted from one electrode to the other through the posit...
