Power Inverter with Conjugate Heat Transfer: Overview

The objective of this simulation is to study the air flow inside a power inverter (air-cooled). Air enters the inlet at a specified pressure of 101325 Pa and exits with a volumetric flux of 0.001 m3/s. You can see the geometry and conditions for the simulation in the figure below:

1. Inlet

2. Inflow Direction

3. Outflow Direction

4. Outlet

Air Density = 1.1614 kg/m3

Air Viscosity = 1.846e-05 Pa.s

Heat Source

• Transformer = 3 W

• Chip Thermal = 2 W

• Transistors(1,2,3,4) = 1 W
