Abstract: To narrow the temperature fluctuation of heating elements in domestic heated tobacco products and promote the sensory quality of those products, an alumina ceramic-based heating element with platinum-based resistance paste conductive track and metallic silver welding plate and pins was experimented, and its temperature field distribution characteristic was analyzed with COMSOL Multiphysics software. Based on the temperature control requirements for heating elements, a temperature control circuit was designed to obtain the temperature field modeling parameters. According to the basic physical parameters and control parameters of the heating element, the multi-physics finite element simulation software COMSOL Multiphysics was used to establish a three-dimensional model of the heating element under the action of thermo-electric coupling and to obtain the temperature variations of the heating element under different working conditions. The simulation results were verified on an in-house test platform. The comparison between the simulation data and the testing data showed that:at the highest temperature, the maximum error between the two was 4.8% in preheating mode; it was 7.1% in constant temperature mode. The simulated values well agreed with the test values and the errors were within an acceptable range, which verified the effectiveness of the model and the simulation method. This technology provides a theoretical basis for the development and quality promotion of heating elements.
