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。
目的：研究燒結多孔管錶麵多孔層的製造工藝，併對銅粉燒結多孔層錶麵的傳熱性能進行測定。方法利用燒結模具在銅管外麵燒結銅粉層，併通過實驗計算齣多孔燒結管的熱通量和彊化換熱繫數。結果銅粉燒結後的銅管在酒精中的彊化傳熱效果達到瞭光管的10倍左右。結論燒結銅粉粒徑越小，燒結管的熱通量越大，其傳熱性能越好。

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 cal-culated through experiments. Results The obtained results showed that the enhanced heat transfer effect of the brass after sin-tering 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.
