Radiators are used to transfer thermal energy from one medium to another for the purpose of cooling and heating. In this work an attempt is made to find out the coupled temp-displacement analysis of a radiator tube element at 615°C in operating condition of a Brazing process to prevent the leakage, which is the major problem facing in the heat exchanger at header and tube joints. A coupled temp-displacement analysis is carried out to find out the temperature, heat flux, stress strain and thermal expansion of radiator tubes (consider 10 different tube dimensions). And based on the expansion of the tubes suggesting the perfect tube expander tool which is used to expands the tube and helps out the preventing the leakage which is occurring at header & tube joint. Present study uses the coupled temp-displacement analysis tool ABAQUS/CAE edition 6.10-2 to perform an expansion study on a radiator tubes.
