Study on Heat Transfer Problems of Gas Pendulum Inclination Sensor

Abstract

According to different mechanisms of thermal conduction, natural convection and heat radiation, relevant physical models are established for the heat transfer of the sensing organ. Based on these models, the heat transfers of conduction, convection and radiation of the sensing organ in the hermetic chamber are calculated. The results indicated that radiation of the sensing organ is very small and can be neglected for the analysis of heat transfer. Heat transfer of conduction is equal to convection in the hermetic chamber; so simplified heat transfer analysis can be made by analysis of conduction in the hermetic chamber.
