Riassunto
The design and development of Pure Electric Vehicles (PEVs), Hybrid Electric Vehicles (HEVs) and Fuel Cell Electric Vehicles (FCEVs) have received more and more attention and become a major focus area of the automotive industry due to their high energy efficiency and eco-friendliness in comparison to conventional vehicles.
In all electric vehicles the battery pack is the main constituent and key to enabling and increasing cost-effective fuel economy. It is one of the most expensive components of the vehicle and its temperature represents one of the most significant factors impacting both performance and lifespan.
In addition, HEVs require the conversion of electric power typically achieved by an Insulated Gate Bipolar Transistor (IGBT) module, which generates a lot of heat. Both heat and thermal dissipation are critical to the reliability of the the electronic equipment but unfortunately the thermal environment of a motor compartment is not suitable for electronics.
It is therefore important to design and implement effective batteries and IGBT thermal management systems.
This thesis will investigate the experimental study performed through the visualisation of flow patterns inside a Flat Plate Pulsating Heat Pipe (FP-PHP) properly designed, seeing as an innovative cooling system in a forward-looking (future-oriented) perspective on its application for thermal management of HEVs components such as batteries and IGBTs. The influence of the FP-PHP’s hydraulic behaviour on the thermal performance will be thoroughly discussed, and in addition some “Automotive Tests” will be proposed.
The whole research has been carried out in Poitiers at the “Laboratoire d’Etudes Thermiques” of ISAE-ESMA (École nationale supérieure de mécanique et d’aérotechnique) during my internship as an indipendent researcher under the supervision of Prof. Vincent Ayel between February and June 2013.
A working paper in regard to this study has also been also presented at the 17th International Heat Pipe Conference (October 13-17,2013) in Kanpur, India
