Revolutionizing Automotive Cooling: A Comprehensive Review on Enhancing Radiator Performance through Nanofluid-Based Heat Transfer Augmentation and Pipeline Integration of Phase Change Materials

Abstract

Abstract: This review explores cutting-edge advancements in automotive cooling systems, specifically focusing on enhancing radiator performance through a dual approach: the utilization of nanofluids for improved heat transfer and the incorporation of phase change materials (PCMs) within radiator pipelines. Nanofluids, engineered colloidal suspensions of nanoparticles in traditional coolants, exhibit enhanced thermal conductivity, leading to improved heat dissipation. The paper provides an overview of various nanofluid synthesis methods and reviews experimental studies showcasing their efficacy in augmenting thermal performance within automotive radiators. In parallel, the integration of PCMs into radiator pipelines introduces a novel dimension to heat management. Phase change materials, with their ability to store and release latent heat during phase transitions, contribute to temperature regulation and energy efficiency. The review explores different types of PCMs, their selection criteria, and summarizes experimental findings related to their incorporation in automotive cooling systems. A significant portion of the paper delves into the synergies and challenges associated with combining nanofluid-based heat transfer enhancement and PCM integration. The discussion underscores the potential for a holistic approach to radiator design, leveraging the complementary benefits of both nanofluids and PCMs. The findings presented in this review offer insights into the evol
