Improvement of the Radiator Structure based on CFD Analysis
Abstract：The flow and heat transfer performance analysis of a radiator under design has been proceeded by the software STAR - CCM +. The results indicate that the air side convection heat transfer coefficient at the front part of the radiator is far above the latter part. And it suggests the utilization ratio of the front part is higher than the latter part. After the thickness of the radiator is reduced, three simulations at air speed at 5m/s, 10m/s and 15m/s were conducted, the single core heat duty of the thinner one is about 75% of the thicker one when the air speed is at 15m/s. And as the speed of air become lower, the ratio becomes higher. So in the same cooling demand, the new radiator can reduce material cost greatly.
