IGBT Introduction

An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch. An IGBT generates significant heat and can be affected by excess thermal energy. Using air cooling or liquid cooling techniques, e.g. heat sinks, this excessive heat can be removed, which can lead to improved performances, thus enabling much higher power densities and more compact modules.

Project description

In this project, the cooling of an IGBT heat sink is simulated by ANSYS Fluent software. The heat sink is in contact with a heat source (with the heat flux of 14583 W/m2) on one side and the air flows on the other side with a mass-flow of 0.25Kg/s. The air-flow is responsible for cooling the heat sink.  Energy model is activated to analyze the heat transfer rate and the Laminar viscous model is activated to solve the air-flow.

IGBT Heat Sink Geometry and mesh

The geometry for analyzing this simulation consists of a heat source and a heat sink. The geometry is designed and meshed in Gambit®. The mesh type used for this geometry is unstructured and the element number is 11872367.


CFD Simulation Settings

The key assumptions considered in this project are:

  • Simulation is using pressure-based solver.
  • The present simulation and its results are considered to be steady and do not change as a function time.
  • The effect of gravity has not been taken into account.

The applied settings are summarized in the following table.
