AI Technical Summary
Existing polypropylene film capacitors have low heat dissipation efficiency and insufficient high-temperature resistance in high-temperature environments, leading to performance degradation or damage.
A dual heat dissipation mechanism is adopted, which combines phase change material and insulating cooling oil to increase the heat transfer area and improve the high temperature resistance through metallized polypropylene film. At the same time, a high temperature resistant jacket structure is designed to enhance the heat dissipation effect.
This technology enables rapid heat dissipation and stability of capacitors in high-temperature environments, reducing performance degradation or damage and ensuring long-term stable operation of capacitors at high temperatures.
