In this paper, the effect of conventional nanofluids including Al2O3, CNC and TiO2 and hybrid nanofluids including Al2O3/CNC and Al2O3/TiO2 on the cooling rate of an automobile radiator was investigated. Hydrodynamic-Thermal simulation was performed using ANSYS Fluent software. The flow rate of the nanofluid solution was in the range of 10 to 100 g/s and the volume concentration of the nanofluid was between 0.1 and 0.9%. The flow temperature of the hot fluid was 45 °C and the temperature of the radiator cooling air was 30 °C. The results showed that hybrid nanofluids, despite increasing the heat transfer coefficient (CHTC), also increased the pressure drop of the system. At 0.9%, The thermal performance efficiency (TPE) parameter analysis showed that hybrid nanofluids including Al2O3/CNC and Al2O3/TiO2 (values 1.5 and 1.42) had better performance than conventional nanofluids including Al2O3, CNC and TiO2 (values 1.30, 1.32 and 1.09). It was also observed that TiO2 nanofluid had a low effect on increasing the thermal performance of the radiator.
