设计了一种新型的传热元件-弹性管束，它具有良好的流体激振响应特性。传热表面的振动可以提高传热系数，同时，管的振动也可以很容易地去除附着在管表面的污垢。对弹性管束在汽水换热器中的传热特性进行了实验研究。建立了弹性管束外表面换热系数的无量纲方程。
A novel heat transfer element called elastic tube bundles has been designed which has excellent response characteristics of vibration induced by the flow. The vibration of the heat transfer surface can increase the heat transfer coefficient, meantime, the vibration of the tubes can also remove the fouling adhered to the tube surface easily. Experiments were carried out on the heat transfer characteristics of the elastic tube bundles used in steam-water heat exchanger. The non-dimensional equations of the outside heat transfer coefficient for the elastic tube bundles were obtained.
