The Study of the Influence of Louver Structure on Flow and Heat Transfer Characteristics of the Corrugated Radiator
Abstract：A 3 D thermal - solid coupling model is established for air side of a corrugated radiator in CFD software star ccm ＋. The influence of different parameters of air velocity and louver structure on radiator flow and heat exchange characteristics is analyzed. It is found that most of the air resistance loss is at the inlet area of louvers, that the front part of louvers transfers heat well and that there is stagnation region at the last half of computational domain. With the increase of louver inclination angle, transfer j factor first increases and then decreases, which reaches peak value at 24°, and friction f factor continues increasing. Heat transfer becomes bad with the increase of louver thickness, while fraction f factor increases at the beginning and then decreases. When the louver pitch increases to some extent, heat transfer j factor and friction f factor increase slowly, even decrease.
