Thermal Solution for 5000W IGBT cooling project.

The design requirements

CASE2:IGBT x 9PCS=5022W;

CASE4:IGBT x 9PCS=5040W;

Fans :700m3/H ，at intake temperature 50℃

Heat sink: Skived fin heat sink with heat pipes

Environment temperature:50℃

The heat sink surface maximum temperature is below 95℃

Design model in Ansys16.0

Meshing Num nodes

Heat sink temperature distribution
