The high quality and the relevance of Anne’s thesis contributed to get significant results as a part of INTEGRATION project.
About this thesis
This kind of plane would be lighter than a usual one. To be sure of this, it is necessary to reduce weight of embedded equipment’s dedicated to management, conversion and distribution of electrical energy.
The sizing and the optimization of embedded equipment’s weight is a critical issue in the development of more electrical aircraft. This weight is mostly defined by heat transfer systems, when we consider the sizing of energy conversion system
A lot of heat transfer system exists and are dedicated to the cooling of power converters. We selected two of these heat transfer system, in order to produce models of them. These models will be used in optimization routines.
Plate fin heat sink in forced convection, and system assembly, combining heat pipe and plate fin heat sink, will be modelled during this thesis. Analytical models of these heat transfer systems will be developed, to optimize their weight and ensure a good cooling of electrical systems.
Even if lots of dimensioning and optimization methods exists, dedicated to heat transfer systems, we choose to use analytical modelling.
This kind of models gives an exact solution to the heat equation, to describe simple geometric and thermic configurations. Selected heat transfer systems can be simply described.
The main advantage of these models is that it represents the thermal behavior of the system as a function of its geometrical parameters, materials and environmental conditions. Execution of these models is very fast and gives a precise solution of the thermal parameters of the described configuration.
There is then a real interest to use this type of models to optimize weight of heat transfer systems, and then power converter.
