Simulation of High Thermal Conductivity Polyurethane DC Support Capacitor

In the field of energy storage, capacitors are receiving more and more attention due to their high power density, long life cycle, lack of maintenance, etc. We have developed a thermoelectric coupling model to simulate the temperature rise of DC support capacitors under normal operating conditions at room temperature and to obtain accurate results. Boundary conditions are established under this model and the temperature rise of the capacitor is shown by iteration as well as solving the partial differential equation. The temperature rise condition of the capacitor is shown by iteration and solving partial differential equations and the actual situation is predicted and investigated. The results show that the capacitor can operate steadily under normal working conditions.
