La recherche et l'optimisation d'outillage de brasage destiné a la fabrication d'échangeurs de chaleur en inconel et super alliage

Abstract : This internship carried out from 15 March to 15 September 2013 and held between the research and development department of the company Fives Cryogenics and technology hall of the European School of Engineering in Materials Engineering "EEIGM" was subject to: Optimization of soldering tool for the manufacture of heat exchangers and super alloy inconel. For optimizing reliability and manufacturing of plate heat exchangers and brazed inconel waves or super alloy, a solution of insulation to limit the operating temperature of the compression elements is necessary, therefore, my first task, process modeling brazing in vacuum furnace has enabled me to have the temperature profiles in the heart of a brazing cycle commonly used in the manufacture of this type of device, then I validated my digital model with experience exchanger prototype. My second task, the integration of the insulation solution clamping tools in the numerical model that I made in two steps allowed me to have satisfying results, which motivated me to do an experiment to see the results of this solution on reality. Finally, I made three standard digital models for the company, which will provide a gains in terms of time and cost for future projects.
