| description | Circuit parameters are the decisive factors for the heating performance of graphite heating elements，and the research on the influence of circuit parameters is the basis for the design of high-performance and high-reliability graphite heaters. The failure process of graphite heating device is investigated，and the reliability quantitative indexes of heating element，temperature uniformity are determined. Four circuit parameters to quantify the output performance are advanced，including the thickness，width of the strip，gap between the strips and radius of the gap rounding. The mechanism of influence of circuit parameters on heating capability and reliability is investigated through coupled thermal electric finite element method analysis. The results show that the thickness can determine the heat output capability，while the remaining three circuit parameters can determine the reliability. The advancements in this paper play an important role in the development of high performance graphite heating device. |
