Experimental and Theoretical Analysis of Headlight Surface Temperature in an Infrared Heated Stress Relieving Oven

Öz

In this study, the IR heated stress relieve oven was experimentally and theoretically examined. In experimental measurements, temperature was measured on headlight surface, placed in IR oven at various conveyor speeds and various distances between IR lamps and headlight surface. In theoretical study, a mathematical model was developed for the headlights surface temperature by using heat transfer theory. The results obtained by the mathematical model and the measurement showed very good agreement with a 6.5 % average error. It is shown that mathematical models can be used to estimate the surface temperatures when the oven is operated under different conditions.

INFRARED ISITMALI GERİLİM GİDERME FIRININDA FAR YÜZEY SICAKLIĞININ DENEYSEL VE TEORİK ANALİZİ

Öz

Bu çalışmada, infrared (IR) lambalar ile çalışan bir gerilim giderme fırını deneysel ve teorik olarak incelenmiştir. Deneysel çalışmada, farklı konveyör hızları ve ısıtıcı mesafeleri için far yüzeyindeki sıcaklıklar ölçülmüştür. Teorik çalışmada ise ısı transfer ifadeleri kullanılarak bir far yüzeyindeki sıcaklıkların tahmini için bir model oluşturulmuştur. Matematik modelden elde edilen sonuçlar deneysel veriler birbirine benzerlik göstermiş ve deneysel veriler ile karşılaştırıldığında ortalama % 6.5’ lik bir fark bulunmaktadır. Matematik modelin farklı çalışma şartlarında far yüzeyinin sıcaklığını tahmin etmede kullanılabileceği gösterilmiştir.
