“…The usage of fins is an effective technique in natural convection heat dissipation engineering applications. Rath et al [40] conducted numerical simulations to explore the implications and performance of wavy longitudinal fins over straight longitudinal fins for heat dissipation augmentation in natural convection; the structure is shown in Figure 7d. It was noted that wavy fins intensified the thermo-buoyant flow and augmented the heat dissipation from the fin surface at certain ranges of the pertinent parameters.…”

Heat sinks are vital components that dissipate thermal energy from high temperature systems, such as aero-space vehicles, electronic chips, and turbine engines. In the last few decades, considerable research efforts have been devoted to heat sinks to enhance heat dissipation, minimize temperature in the hot spot region, and reduce the temperature of hot section components. At present, the improvement of the thermal performance of heat sinks encounters many bottlenecks and demands the implementation of new designs, new materials, and flexible manufacturing. This study summarized the recent development of heat sinks over five years with a major review of heat transfer aspects, i.e., conduction, convection, radiation, phase change, and nanofluids technology, as well as perspectives in the aspect of structural design. The purpose of this work is to provide an overview of the existing studies that elevate the thermal performance of heat sinks and propose prospectives and suggestions for future studies.

“…He concluded that heat flux strongly influences the heat transfer rate and, more so, HS with perforated fins performed better than others. Rath et al [7] numerically examined the thermal characteristics of radial HS consisting of longitudinal corrugated fin with three different number of cycles (one cycle, two cycles, and three cycles). They revealed that the highest value of fin effectiveness and Nusselt number was obtained in corrugated fins with three cycles, followed by two cycles and one cycle.…”

“…Heat dissipation has become a critical issue in the development of electronic devices and equipment and has a significant impact on their performance, service lifetime, and reliability. [1][2][3][4] To resolve this issue, thermal interface materials (TIMs) are employed to prepare electronic packaging for heat conduction improvement. [5][6][7][8] Polymers have been widely used as a matrix to fabricate TIMs owing to their low cost, electrical insulation, and easy processability.…”
