Abstract:	To enhance the heat transfer performance of louver radiators in all-terrain vehicles (ATVs) and reduce operational noise, numerical simulations were conducted using Fluent to analyze the heat transfer and noise characteristics of the radiator with varying louver angles under different operating conditions. The results indicate that the heat transfer and noise performance of the louver radiator are lower under high-load conditions compared to low-load conditions. For the same operating conditions, a larger louver angle corresponds to reduced heat transfer performance; specifically, the JF evaluation index for a 15° louver is 66.4% higher than that for a 40° louver. The noise performance decreases as the shutter angle increases, reaching its peak at 15 °, which is 42.45% higher than the lowest performance observed at 40 °. The comprehensive evaluation reveals that the optimal balance between noise and heat dissipation efficiency is achieved with a louver angle of 20 °, which is 25% higher than the lowest evaluation at 40°. These findings provide valuable engineering insights for the design and optimization of ATV radiators. [ABSTRACT FROM AUTHOR]
