摘要
Indium tin oxide(ITO)heating film is primarily used as the defogging component of an instrument observation window.Conventionally,a constant current is used to heat the film.Through the feedback of the temperature sensing component,the output current is adjusted to achieve a set temperature.However,the temperature of the heating film is nonuniformly distributed,and determining the correct output current is time-consuming.This study adopted finite element heat transfer analysis to determine a heating method(such as heat power and heat flux)for an ITO conductive heating film system.The results of the analysis may serve as a reference for temperature compensation in ITO conductive heating films.
