【 摘 要 】

Reliability of power electronic modules is a key characteristic of existing and innovative modules. An increasing quantity of these modules is used in a large range of applications and addresses from annex up to vital functions, especially with the more electronic aircraft and recent developments in transport applications. To propose a solution to this lifetime issue, Microsemi and EHP have designed, manufactured and tested an improved flat heat pipe to fulfil aeronautic requirements. The frame of this development is based on the existing SP3 power module of Microsemi and significant decrease of thermal resistance is demonstrated by thermal tests.
