计算了不同条件下多孔铝的对流换热系数。结果表明,随着孔径的减小,多孔铝呈现比表面积增加,流通性能降低的趋势。随着风速的增加,多孔铝的换热系数变大。风机功率相同时,多孔铝的孔隙率增加,换热系数提高。 The convective heat transfer coefficients of porous aluminum under different conditions were calculated. The results showed that with the decrease of the pore size, the specific surface area increased and the flowability decreased. As the wind speed increases, the heat transfer coefficient of porous aluminum becomes larger. When the fan power is the same, the porosity of porous aluminum increases and the heat transfer coefficient increases.
