Research on Structure Optimization Based on Solid Heating Elements

Abstract

Heating elements are found to be prone to structural and functional problems such as adhesion and short circuit in engineering practice, which is due to illogical structural design and spatial arrangement of electric heating components. To overcome the foregoing difficulties, the structural parameters of the electric heating element are optimized using the finite element method, and the heat transfer properties of the device are studied. By varying the structure, diameter, and surface load of the heated wire, the heat transmission effects are compared. The experimental findings reveal that by reducing the surface temperature of the corrugated linear wire over the same surface area, the surface load of the heating system may be effectively lowered. The experimental results show that, for the same surface area, the corrugated linear band can effectively reduce the surface temperature; increasing the diameter of the linear heating wire can reduce the surface load and improve the service life of the heating wire, and the temperature decrease is not obvious when the linear heating wire diameter exceeds 8mm; increasing the heating wire power or surface load can increase the heating wire surface temperature;
