Heat produced inside internal combustion engines can become the cause of engine damage and failure. The engine cooling system in vehicles plays a crucial role to avoid damage as a result of internal heating. Thus, the role of radiators in removing excessive heat from the engine is important. Nanofluids are used in this regard to improve the heat transfer performance of radiators. Among different nanofluids, Al₂O₃/water and ZnO/water nanofluids have been proven better heat transfer coolants for automobile cooling systems. Therefore, in this study, we developed the automotive radiator test rig to compare the performance of ZnO/water and Al₂O₃/water nanofluids. The radiator test rig was modified to find accurate results. The overall comparison between both nanofluids showed that Al₂O₃ nanoparticles are more effective as compared to ZnO nanoparticles in the coolant.

内燃机内部产生的热量会成为发动机损坏和故障的原因。车辆的发动机冷却系统在避免因内部加热而造成损坏方面起着至关重要的作用。因此，散热器在去除发动机过多热量方面的作用非常重要。纳米流体在这方面被用于改善散热器的传热性能。在不同的纳米流体中，Al ₂ O ₃ /水和ZnO /水纳米流体已被证明是用于汽车冷却系统的更好的传热冷却剂。因此，在这项研究中，我们开发了汽车散热器试验台来比较 ZnO/水和 Al ₂ O _3的性能/水纳米流体。修改了散热器试验台以找到准确的结果。两种纳米流体之间的总体比较表明，与冷却剂中的 ZnO 纳米颗粒相比，Al ₂ O ₃纳米颗粒更有效。
