Highest temperature of heating body: 123 ℃ (for reference only, please use actual measurement)

  IGBT heat sink thermal analysis result(fin close)

Flow model : Turbulent (zero-equation) 

The heatsink temperature distribution is up to 119 ℃  

Conclusion:  

Ambient temperature : 40℃

Maximum temperature of  IGBT heat sink (fin open)：121 ℃

Maximum temperature of  IGBT heat sink (fin close)：119 ℃

Heat pipe suitable for above 100 ℃ high temperature should be selected, otherwise the heat pipe may burn out.

The highest temperature below 125 ℃ is required by the customer.
