In
order to improve the performance of vehicle radiators, a two-dimensional heat
transfer steady-state model of the radiator was set up. The influence of the
structural parameters (axial ratio) of the heat exchange tube on the windward
side on the heat transfer performance of the radiator was studied. With the
increase of the axial ratio of the heat exchange tube on the windward side, the
heat exchange capacity of the heat exchange tube surface slightly decreases. The
heat exchange area increases significantly, which increases the total heat
exchange of the radiator and improves the heat transfer performance of the
radiator. When the axial ratio increases from 1.0 to 2.0, the average surface
heat transfer capacity decreases from 5664.16W/m2 to 5623.57W/m2.
