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.
