Paragraph Number

79

Preferably, the graphite element 804 converts electric energy to thermal energy in a substantially consistent manner throughout the graphite element. In such an embodiment, a heat spreading element 210 may be omitted from the thermal cover 800 since the graphite 810 serves the purposes of conveying current, producing heat due to resistance, and evenly distributing the heat. Advantageously, the graphite 810, substrate 812, and protective layer are very thin and light weight. In one embodiment, the combination of graphite 810, substrate 812, and protective layer forming the graphite element 804 may be between about 3 and about 20 thousandths of an inch thick. Preferably, the graphite 810 is between about one inch wide and about 10 inches wide and and between about 1 thousandths of an inch thick and about 40 thousandths of an inch thick. In a more preferred embodiment, the graphite 810 is about 9 inches wide and about five thousandths of an inch thick.
