This paper aims to analyze the heat transfer characteristics of a double-array helical elastic tube bundle heat exchanger with vibration. The characteristics were investigated by using a bidirectional fluid–solid coupling calculation method with different winding numbers and inlet-flow velocities. Results indicate that in the shell-side fluid, the greater the flow velocity, the more the turbulent energy of fluid, the stronger the turbulence characteristics, and the better the heat transfer effect. In the shell-side fluid, the process of heat exchange is a heat accumulation process: the greater the flow velocity, the more heat absorbed by the fluid in a unit of time, and the better the heat transfer effect. The performance evaluation criteria (PEC) have increased by 2.33%, and the average volume heat transfer coefficient (HTC) has increased by 80.80% when the inlet-flow velocity is constant, as the winding number increases. In addition, PEC has increased by 7.84%, and the average volume HTC has increased by 3.6 times when the winding number is constant, as the inlet-flow velocity increases.

本文旨在分析带振动的双列螺旋弹性管束换热器的传热特性。通过使用具有不同绕组数和入口流速的双向流固耦合计算方法来研究特性。结果表明，在壳程流体中，流速越大，流体的湍流能越多，湍流特性越强，传热效果越好。在壳程流体中，热交换过程是一个蓄热过程：流速越大，单位时间内流体吸收的热量越多，传热效果越好。性能评价标准（PEC）提高了2.33%，平均体积传热系数（HTC）提高了80。当入口流速恒定时，随着绕组数的增加，为 80%。此外，随着入口流速的增加，PEC增加了7.84%，在绕组数不变的情况下，平均体积HTC增加了3.6倍。
