An Analytical Approach to Solving Induction Ring Heat Dissipation Problem

The paper first introduces the working principle of induction vibration table, then establishes a simplified transformer equivalent circuit, and derives the mathematical model of the induction vibration stable. When the current density on the surface of the induction ring is high, the temperature of the induction ring will continue to rise if relying solely on air cooling for heat dissipation. Therefore, this article presents the spray cooling method, which is formed by spraying pure water with a high-pressure gas, and spray evenly on the surface of the induction ring through a plurality of nozzles. Thus, the steam fog is formed on the surface of the induction ring, thereby achieving the purpose of cooling effect. The thermal deformation and stress distribution of the induction ring at 100 ℃ and 200 ℃ are analyzed by thermal simulation. Finally, the surface temperature of the induction ring is measured in 80G random vibration test to verify the effectiveness of the spray cooling method.
