| 摘 要： | 目的研究烧结多孔管表面多孔层的制造工艺,并对铜粉烧结多孔层表面的传热性能进行测定。方法利用烧结模具在铜管外面烧结铜粉层,并通过实验计算出多孔烧结管的热通量和强化换热系数。结果铜粉烧结后的铜管在酒精中的强化传热效果达到了光管的10倍左右。结论烧结铜粉粒径越小,烧结管的热通量越大,其传热性能越好。

| Abstract: | Objective To study the manufacturing process of porous surface coating of sintered porous tube, and the heat transfer properties of copper sintered porous layer surface were measured. Methods Copper powder was sintered on the outside layer of brass using sintering mold, and the heat flux and enhanced heat transfer coefficient of the porous sintered tube were calculated through experiments. Results The obtained results showed that the enhanced heat transfer effect of the brass after sintering copper reached about 10 times as high as that of the light pipe in alcohol. Conclusion The smaller the particle size of sintered copper powder, the greater the heat flux of sintered tube and the better the heat transfer performance. |
