Abstract

In the present study, a computer program is developed which can be used for thermal analysis of Radiators with corrugated Louvered Fin and flat tube. This program is able to capture all the geometry-dependent aspects of heat transfer regarding these Radiators. It also gains the capability of capturing the air flow non-uniformity through the Radiator. The program showed a good agreement when it was tested against experimental data. The maximum error in the experimented range of Cooling flowrate and air velocity is 5%. Two important parametric studies have been performed on air mal-distribution and Radiator aspect ratio effects on the Radiator thermal performance. Results show that air mal-distribution reduces thermal performance by 20%. Increasement of aspect ratio introduces up to 45% performance improvement. Finally, a novel efficient geometry for fin profiles has been introduced and its improving effect on thermal performance is shown using the program.
