本文对空气流过镍、铜材料泡沫金属结构和2种板翅结构的对流换热进行了实验研究。结果表明:在本文实验参数范围内,与空槽道相比,两种板翅结构分别使空气的对流换热系数增加了3～5倍和7～9倍;相同的实验条件下镍、铜材料的泡沫金属结构分别使空气的对流换热系数增加了9～11倍和10～12倍;与相近孔隙率的板翅结构相比,泡沫金属结构的流动阻力更大些。本文还对泡沫金属与板翅结构内的对流换热进行了数值模拟,得到较好的模拟结果。 In this paper, convection heat transfer of air through the foam metal structure of nickel, copper and two kinds of plate-fin structures were experimentally studied. The results show that the air convection heat transfer coefficient increases by 3 ~ 5 times and 7 ~ 9 times respectively compared with the empty channel in the range of experimental parameters. Under the same experimental conditions, The foam metal structure of the material increases the air convection heat transfer coefficient by 9 to 11 times and 10 to 12 times, respectively. Compared with the plate-fin structure with similar porosity, the flow resistance of the foam metal structure is larger. In this paper, numerical simulation of convective heat transfer in foam metal and plate fin structure is also carried out, and good simulation results are obtained.
