摘 要: 介绍了管翅式换热器管外翅片强化传热的措施及其最新研究进展 ,总结了不同翅片形式强化传热的机理及翅片参数对传热与流阻的影响规律。提出了翅片尺度的新概念 ,并指出了今后的研究方向。 The measurements and up to datestudy advances for the heat transfer enhancement of outer fins in tube-fin heatexchangers are reviewed, the mechanism of heat transfer enhancement and effectof fin parameters on heat transfer and flow resistance are summarized. Meanwhile, the novel concept of fin scale is proposed and further research direction is given.
