The growing demand for energy and the necessity to enhance the efficiency of heat exchangers have triggered numerous studies aimed at improving convective heat transfer rates while simultaneously reducing the size and investment costs of industrial devices. In this comprehensive review, a thorough analysis of recent literature has been undertaken to explore the latest advancements in tubular, plate, and extended surface heat exchangers, considering factors such as geometry, materials, and heat transfer fluids. The review comprehensively covers passive, and combined approaches to convective heat transfer (CHT) enhancement in these heat exchangers. Consideration is afforded to research studies exploring passive techniques in double pipe heat exchangers (DPHEXs), plate heat exchangers, and extended surface heat exchangers. The review extensively explores surface modifications such as corrugated surfaces, twisted tapes, and rough surfaces in heat exchangers. It provides detailed insights into the impact of these modifications on CHT rates and overall heat exchanger performance. The review also encompasses an examination of different chevron angles and the use of various refrigerants in plate heat exchangers. It offers a comprehensive overview of the effect of these factors on the performance of plate heat exchangers. Furthermore, the review examines an analysis of various types of fins utilized in different heat exchangers, exploring their effectiveness in conjunction with different heat transfer fluids. This examination provides insights into the interactions between fin configurations and heat transfer fluids, contributing to a comprehensive understanding of their impact on heat exchanger performance. Moreover, the review comprehensively covers the utilization of different nanoparticles and nanomaterial sizes in car radiators, highlighting advancements in real-time application. Additionally, it explores the use of various types of extended surfaces and nanofluids in different heat exchangers, providing a detailed analysis of their impact on heat transfer enhancement. The examination also includes a review of water-based nanofluids and their diverse applications in various heat exchangers, shedding light on the evolving landscape of nanofluid technology in the field.
