| Abstract: | In this paper, exergy analysis method is presented for assessing the performance of automotive radiator with corresponding analysis model set up. The exergy efficiency is put forward as an assessment indicator for thermal performance of automotive radiator. Through the thermodynamics analysis on the irreversible exergy loss of radiator caused by temperature differences and viscous friction resistance, the calculation formula of exergy efficiency is derived. And the related computation and analysis are conducted based on test data of a specific tube- and- fin automotive radiator. |
