本文在风洞实验台上,对椭圆矩形翅片管束和圆管圆形翅片管束进行了对比性实验,归纳出了换热与阻力的无因次经验公式,对于管内蒸汽冷凝,管外空气横掠管来的工况,椭圆矩形翅片管具有较优的换热与阻力性能。最后,讨论了一些有关椭圆矩形翅片管冷凝器的优化问题。 In this paper, wind tunnel experiment platform, the elliptical rectangular finned tube bundles and circular tube finned tubes were compared, the inductive heat transfer and resistance of the non-dimensional empirical formula for the tube vapor condensation, outside the tube air Horizontal swept pipe to the conditions, the elliptical rectangular fin tube has excellent heat transfer and resistance properties. Finally, some optimization problems related to elliptic rectangular finned tube condenser are discussed.
