摘要 提出了海生物通流能力强的二壳程二管程管壳式换热器方案,为了增强管壳式换热器的换热能力,降低流致振动风险,在多个维度上对其具体结构进行了设计分析。基于管壳式的结构方案,针对其热工设计工况参数进行了热工水力计算分析,结果表明,该管壳式换热器的换热、压降和流致振动均满足设计要求。 A two-shell-pass and two-tube-pass shell-and-tube heat exchanger with strong flow capacity of marine organisms was proposed.In order to enhance heat exchange capacity of the shell-and-tube heat exchanger and reduce the risk of flow-induced vibration,the specific structure of this two-shell-pass and two-tube heat exchanger was analyzed and designed in multiple dimensions.In addition,based on the shell-and-tube structure,thermal-hydraulic calculation and analysis were carried out for its thermal design parameters.The calculation results show that,the heat transfer,pressure drop and flow-induced vibration of the shell-and-tube heat exchanger proposed can meet design requirements.
