摘　　要：基于模拟正交试验法并通过Fluent软件分析,开发出新型等弦波形强化换热管(D=10 mm,L=45 mm,R=50 mm),分析得出了较大的法向分速度冲刷壁面是影响其对流换热的主要因素;利用场协同理论分析了等弦波形管的强化换热原理,计算出协同角,通过与直管对比发现,协同角有明显减小,局部达10°以上;最后从泵功耗指标出发,计算得出与直管相比,换热效率提高47.6%,验证了新型等弦波形强化换热管具有较优越的热工性能。The equal chord waveform heat tansfer tube（D=10 mm,L=45 mm,R=50 mm）are devel-oped by simulation orthogonal experimental method and field synergy principle.The large normal velocity to wall is the primary factors of affecting convective heat transfer performance are analysed.Then the en-hanced heat transfer theory of the equal chord waveform heat transfer tube is studied by using the field synergy principle,and the synergy angle is calculated.Compared with straight tube,the synergy angle de-creased significantly,local up to more than 10°.Finally the predominant thermal performance of the equal chord waveform heat tansfer tube is proved in accordance with the power of pump.
