对不同翅片间距、不同管排数的9个正弦波纹翅片管换热器元件进行了试验研究,给出了工业常用雷诺数范围内各元件翅片侧空气的换热和阻力性能关联式。文中还给出了包括翅片间距及管排数影响的通用关联式,为设计和选用正弦波纹大套片换热器提供了依据。
The experimental results of nine sinusoidal corrugated fin tube heat exchangers with different fin pitch and tube row number are given. The correlations between the heat transfer and the resistance performance of the air in the finned side of each component are given in the range of common Reynolds numbers. . The paper also gives a general correlation including the influence of the fin pitch and tube row number, which provides the basis for the design and selection of large sinusoidal corrugated heat exchanger.
