Abstract

Aluminum heat sink cooling fin which are especially used for cooling electronic circuits,
are directly related to their heat transfer capability and design. In heat transfer, the most important
factors are the surface area where the heat is taken, the fin length, the distance between the fins, the
airflow rate, and the thermal conductivity. In this study, the effects of the width between the fins on
the heat transfer were investigated. In the study, the dimensions of the rectangular finned cooling
plate were 200 mm in width, 200 mm in length, 25 mm in fin height, fin spacing between 4 and
2.5 mm, fin thickness of 0.5 mm and the number of fins between 100 and 66 pieces. The plate surface
dimensions were kept constant, the fin spacing was narrowed, and the number of fins was increased.
It was measured that the total heat wool transferred from the fins on the plate surface increased. The
airflow rate was increased from the side surface of the plate and it was observed that the total heat
load ejected from the rectangular fins increased.

Keyphrases: 'fin heat sinks', Finned surfaces, heat transfer
