An effective thermal capacitor is achieved by minimizing conduction length through the PCM by more than 50 times and maximizing surface area with the use of a finned heat pipe structure embedded in the PCM.
On the basis of reasonable simplifications and assumptions for capacitor structure, a 3-D temperature field numerical simulation model for a self-healing power capacitor is formulated in Fluent 15.0. The ambient temperature is set to 55 °C, and the applied voltage is ac 400 V.
The ambient temperature is set to 55 °C, and the applied voltage is ac 400 V. The temperature distributions of the shell and core of the self-healing capacitor are obtained. The results reveal that the temperature of the core is 2 °C-3 °C higher than that of the shell.
For every 10 °C increase in operating 772 temperature, the life of the electrolytic capacitor reduces by half , . But, there is a 773 temperature range where the theory of lifetime is not applicable. Indeed, for a temperature higher 774 than 100 °C, the temperature acceleration factor is different.
Every 10° C increase in internal temperature halves the component lifetime. The structure and materials used in the capacitor make heat dissipation more difficult. To operate properly, the case must be electrically isolated from the core where heat is generated. The voltage breakdown of the insulation materials is often in excess of 350 volts DC.
Concerning the self-healing of polymer-based capacitors, they have a polymer playing 576 the role of an electrolyte. There is also the phenomenon of self-healing for this type of electrolytic 577 capacitor. As seen previously, the leakage current will generate a rise in temperature.
