Design of Electromagnetic Heating Molten Salt Thermal Storage Device and the Distribution Strategy of Thermal Storage Metering Sensors

Thermal energy is essential in both daily life and industrial applications. Molten salt phase‐change thermal storage technology provides an effective solution for improving thermal energy utilization. However, traditional thermal storage systems face several challenges, including low heat transfer efficiency and difficulties in measuring thermal storage. These limitations hinder the widespread adoption of molten salt thermal storage technology. To address these issues, this article presents the design of an electromagnetic heating molten salt thermal storage device. The study simulates and analyzes the thermal behavior of the device under various heating conditions. Based on the simulation results, this article compares and analyzes the heat distribution patterns of molten salt at different cross sections. This article also investigates the heat density distribution in the thermal storage device. By selecting the optimal temperature sensor location, the study proposes a heat metering scheme for the molten salt thermal storage device, achieving accurate measurement of the device's thermal storage capacity.
