The aim of this paper is to present a simulation to optimization the structure of radiator, in this paper the spacing of radiation fin and goose neck height are considered. The simulation is designed to predict their influence on the heat transfer efficiency based on CFD software. A best structure of radiator can be developed according to the simulation results and provide guidance for the practical application of engineering.

The author used CFD software to simulate when group panel-type radiator quantity, space, height of gooseneck have changed, how temperature distribute on the radiator. To obtain when group panel-type radiator quantity, space, height of gooseneck and other factors have changed, the laws of heat transfer efficiency changed and analyzed the reasons for emergence of such laws in theory. The optimal group of panel-type radiator improvement program is explored, to provide guidance for the practical application of engineering.
