【Abstract】 The small channel technology was used to design and develop a new kind of steel-aluminum column-wing-type radiator. A mathematical model of the steel-aluminum column-wing-type radiator was constructed. The theoretical analysis was carried out and the size of the new radiator was decided by the heat dissipation of 700 W. Simultaneously, the heat dissipation of the traditional radiator was calculated on the basis of mathematical model. At the same time the experimental study of the traditional radiator’s heat dissipation was carried out to confirm the precision and accuracy of the mathematical model. The numerical simulation of the temperature field, velocity field and pressure field of the new kind of steel-aluminum column-wing-type radiator and the traditional one were also made. Finally,the economic efficiency of the two kinds of radiators was also analyzed. It was concluded that the new steel-aluminum column-wing-type radiator excells in heat dissipation and economic efficiency compared with the traditional one.更多还原
