Thermal management systems play a crucial role in not only reducing energy losses but also optimizing thermal performance, extending system lifespan, and enhancing energy efficiency. Integrated thermal management systems (TMS) differ from conventional cooling systems by combining active and passive cooling components into a single, unified system, offering a more efficient and sustainable thermal management solution. These systems aim to maximize performance and reliability by ensuring the operation of electronic components, power units, and various industrial equipment within their optimal temperature ranges. In the design of integrated TMS, the influence of different geographical regions and varying climatic conditions emerges as a significant factor. Thus, in addition to current system configurations, the development of customized integrated TMS designs that account for regional climate variations can contribute to improved system performance. In this study, the thermal responses of the radiator, a primary cooling system component of integrated TMS, to transitional seasonal climate conditions were experimentally investigated for two different scenarios. The applied heat fluxes in the scenarios were q''= 9.06 W/cm² and q''= 18.12 W/cm². The thermal behavior of the heat transfer fluid (HTF) and the phase change material (PCM) with latent heat storage capacity was evaluated within the system. The findings revealed that even under a challenging scenario with a 42% increase in HTF inlet temperature, the PCM maintained the system within its optimal temperature range. Moreover, a 25% reduction in thermal load was observed in the system. These results demonstrate that the use of materials like PCM in integrated TMS designs significantly contributes to thermal balance and energy efficiency.
