[Abstract]:Based on the study of the influence of the heat dissipation on the heat dissipation performance, a three-dimensional model of the shutter radiator is established, and the coupled heat transfer principle is applied to simulate the heat transfer process. The inlet and outlet pressure drop, fin heat transfer coefficient and heat transfer quantity of the radiator under different wind speeds are obtained. The influence of the waist-closing tube on the fluid structure and distribution of the air passage of the shutter radiator is summarized. By comparing and analyzing the performance difference of many kinds of tube radiators through wind tunnel test, it is found that the radiator of the take-up tube has better heat dissipation performance and can meet the cooling requirements of various types of engine cooling system.
