In this study, heat transfer enhancement occurred from turbulence of flow by fin was considered. Fins were arranged in in-line form, and longitudinal pitch Sp and lateral pitch Sn were varied. Cool air flows through the slant fin array to take away heat from the heated plane. Visualization of temperature distribution image was processed by color image processing to determine the quantitative temperature distribution by a hue angle-temperature correlation curve. The flow around the fin array was visualized using talc powder. Average Nusselt number on the heated plane was calculated from the quantitative temperature distribution. Coefficient of pressure of flow passage loss was also calculated by pressure loss.
