Extruded Tube Solutions for CoD2 Heat Exchanger Applications-Materials and Component Design
Published May 18, 2003 by Institution of Mechanical Engineers in United Kingdom
The Automotive Industry is now considering the introduction of CO2 mobile-air-conditioning systems to substitute present R134a systems. One implication of CO2 MAC systems is the increased operating pressure and temperature compared to R-134a systems, leading to different designs and aluminum materials for components making the CO2 system.
By material development, computer simulations and experiment, Hydro Aluminium has optimized some CO2 extruded tube application to ensure that today's components for existing refrigerants can be effectively replaced.
New aluminum alloys will emerge during the next few years with a better combination of functional properties as elevated temperature strength, brazeability and corrosion resistance compared to materials applied in today's solutions.
