“…The interfaces between the fluid and the cooler body, including the nozzle plate, inlet and outlet tubes, are assumed to be adiabatic. Previous work has demonstrated that the heat transfer through the solid cooler, which is denoted as ‘Jet cooler’ in figure 1( a ), is negligible as the convection between fluids and the porous medium dominates in this scheme (Wei et al. 2020 a ).…”

“…Sridhar (2013) compared the performances of different cooling solutions and found that the HTC of single-phase impingement jets is at least one order of magnitude larger than that of forced convection. Additionally, recent research by Wei et al (2020a) demonstrated that single-phase water impingement jets can achieve an average HTC of up to 6 × 10 4 W (K • m 2 ) −1 on the targeted surface. However, the non-uniformity of the HTC on the targeted surface remains a significant drawback of impingement single jet cooling (Bhunia, Chandrasekaran & Chen 2007), leading to a substantial temperature gradient along the chip surface and affecting device performance.…”

“…2018; Patil & Hotta, 2018; Wei et al. 2019 a , b , 2020 a , b , 2022). Due to the thin hydrodynamic and thermal boundary layers generated by the impingement jet, single-phase liquid impingement jet cooling can achieve a much higher heat transfer coefficient (HTC) than conventional cooling schemes, particularly in the stagnation region.…”

In this study, we propose a novel cooling scheme that utilizes copper inverse opals (CIOs) for surface enhancement in a single-phase impingement jet cooling system. We perform computational fluid dynamics simulations to evaluate the cooling performance of the CIO jet coolers. Our modelling results indicate that the proposed CIO-coated cooler can significantly reduce the average temperature and improve the temperature uniformity across the entire chip surface. The average Nusselt number of the CIO-coated cooler can reach up to 2.8 times that of the flat surface jet cooler. However, the porous structure of the CIO-coated cooler increases the total pressure drop. To determine designs with high cooling performance and low energy consumption, we investigate two crucial design factors, namely the inlet velocity and the nozzle-to-CIO distance. Our analysis reveals that increasing the inlet velocity further enhances the heat transfer, but at the expense of high pressure drop. On the other hand, a larger nozzle-to-CIO distance results in a lower pressure drop but also reduces the heat transfer coefficient. The effects of nozzle-to-CIO distance are further understood by studying the flow resistance network. Furthermore, we present a reduced-order model that accurately captures the thermofluidic characteristics of the proposed design.

View full text Add to dashboard Cite

This review provides a brief literature survey on enhanced heat transfer research published in the English language journals in 2020. A topic search containing either "heat transfer" or "heat transport" or "thermal transport" in the Web of Science resulted in over 28,000 papers published in 2020 and nearly 30% were relevant to heat transfer intensification, which indicates the importance and rapid development of heat transfer enhancement technologies. The chosen studies focus on various heat transfer enhancement research categorized into conduction, convection, radiation, boiling and condensation, energy storage, thermal management, and cross research involving two or more categories. Heat conduction papers are selected from the micro/nanoscale areas with a focus on interfacial phenomena. Important active, passive, and compound techniques for enhancing convective heat transfer are incorporated. Thermal radiation is concentrated on near-2 field radiation and solar energy. Heat transfer enhancement in boiling and condensation as well as in thermal energy storage, renewable and sustainable energy, and thermal management of electronics and high-end equipment is critical in many engineering applications. From the selected literature published in 2020, significant attempts have been made to research and development on heat transfer enhancement technology covering both conventional and emerging techniques. The prospects of the heat transfer enhancement research are reflected according to the literature survey.Research of innovative heat transfer enhancement techniques is immense, encompassing every aspect from understanding the fundamental theory and physical mechanisms of various heat transfer enhancement techniques to their applications. Research of emerging techniques using new interfacial materials, nanofluids, micro-and nano-structures, microchannels, and new compound enhancement techniques incorporating conventional and new techniques becomes popular.However, there are big challenges in understanding the mechanisms, engineering design methodology and applications with these emerging techniques. Many aspects are urgently needed to be investigated and developed to achieve systematic theory, mechanisms and design methodology for applications in thermal processes, energy storage, renewable energy, decarbonized heating and cooling and many industrial and civil sectors.
