Abstract
This paper proposes a new methodology for microchannel heat exchangers design. It uses the basic principle of minimize flow resistance, stated by the Constructal Theory, to build the internal channels geometry. Unlikely the usual design methodologies where channel form is a predefined parameter, in this work its geometry is constructed. Flow and heat transfer problems are solved and an internal (to the channel) fin is make to evolve such as heat exchange between fluid and solid is maximized. This extended abstract presents the problem and validates the CFD solution by direct comparison with literature data. Contructal form for the heat exchange will be presented on the final version of the paper.
