摘要

The effects of inclined angle on the heat transfer of radiators under natural convection are analyzed with experiment and numerical simulation, there are three radiators with straight fin. oblique fin and pin fin respectively (based on 150×l50×45mm). The numerical simulation could agree with the experiment. The straight fin radiator could provide the best heat dissipation performance under experimental conditions and normal installation angle. The pin fin radiator has the largest heat transfer coefficient, around 7 W/m~2 ・ K . The influence of deflection angle is discussed on the heat dissipation capability of the radiator. The heat dissipation of the pin fin radiator is less sensitive to the gravity direction than the straight fin and oblique fin ones.
