“…It is interesting to note that the dissipation area in the W-type fins was 10% less than that of parallel plate fins. Park and Lee, 2017;Sahoo et al, 2018)] studied the effectiveness of an inclined cross-cut cylindrical heat sink for LED bulbs. They summarized that by varying the operating angles, the thermal efficiency could be improved.…”

This article provides an in-depth overview of thermal heat sink design and optimization. Heat transfer enhancement strategies are discussed in detail, followed by fin design trends and geometries, and a discussion on different fin configurations and their merits is also presented. Important results and findings of experiments concerning the design and optimization of fin geometries have been summarized. For complex heat dissipation applications, researchers have been studying different fin arrangements especially, inclined fins, to maximize the performance of the heat sinks. Along with innovative fin designs, microchannels for heat dissipation are gaining attention due to their. Recent advances in this domain have been discussed. New components are becoming more compact and advanced as a result of technological breakthroughs in electronics and control systems; hence, the use and optimization of heat sinks for modern applications are also discussed in this article.

“…Sahoo et al 10 investigated the natural laminar convection heat enhancement augmentation from the square-sized conductive horizontal and inclined extended surface arrays. They also numerically explained the heat transfer enhancement with extended surfaces or fins; and also found a correlation to predict the average Nusselt number.…”

The present study includes computational fluid dynamics analysis and comparison of heat enhancement through different extended surfaces, especially in rectangular and square conductive and nonconductive fins. Computational and numerical analysis of heat transfer from a rectangular extended surface and a pin-finned plate studied to calculate the average Nusselt number in parallel, vertical direction placed along the sidewall. The total rise of the mean Nusselt number is noticed around 36% in pin-finned plate with respect to a plain plate. This is examined with optimal fin spacing of S v with L ratio equals to 0.2 and S h with W ratio equals to 0.25, height of extended surfaces 24 mm with 45°angle of inclination. The mean Nusselt number reduces with a rise in the angle of inclination and also increases with a rise in aspect ratio. The present study reveals that inline and staggered arrangements do not yield appreciably different results. The maximum average Nusselt number difference between conductive and nonconductive fins is around 5% for S h per W ratio 0.33 and S v per L ratio 0.2 at an angle of inclination 45°, fin height of 6 mm (height to thickness ratio 2).
