Abstract

In the study, a numerical analysis is conducted to investigate the heat transfer characteristics of an inverter system inside a panel for three locations (bottom, middle and top). A conjugate heat transfer is simulated using a CFD (computational fluid dynamics) code since the heat transfer through the surrounding panel walls is important. It is shown that the heat flux through the left wall, which is important for the safety of the electronic equipment, is the biggest when the inverter is located at bottom. On the other hand, the heat flux through the left wall is negligible when the inverter at middle or top. It is also found that the heat flux to the surrounding walls is the lowest when the inverter is at middle.
