Heat transfer will worsen if structure parameters of the spring inserts are not fit. The paper think that the mechanism of heat transfer enhances of the spring inserts is the laminar flow lining is thinner because of librating of the spring inserts, accordingly the part of convection is enhanced. But the part of boil is not influenced.

通过弹簧插入物的各个参数对传热性能的影响分析，认为弹簧插入物对竖管降膜蒸发传热强化的机理主要是弹簧的振动加强了液膜的湍动，减薄了层流内层，从而强化了对流传热分量，但对沸腾传热分量没有影响。
