本文对急冷换热器各换热管中的气体分配机理作了较完整的分析. 各换热管的流量分配不均匀性决定于换热管的阻力系数不均匀性和进口分配器的分配性能.当换热管的阻力压降远大于分配空间的动压时,进口分配器的分配性能就没有多大影响. 最后提出了根据模型试验数据来予测换热器原型上各换热管分配不均匀性的方法.
In this paper, the gas distribution mechanism in each heat exchanger of quench heat exchanger is analyzed more completely.The non-uniform flow distribution of each heat exchanger depends on the inhomogeneity of the resistance coefficient of the heat exchanger and the distribution performance of the inlet distributor When the pressure drop of the heat exchange tube is much larger than the dynamic pressure of the distribution space, the distribution performance of the inlet distributor has little effect.Finally, the distribution of the heat exchangers in the prototype of the heat exchanger based on the model test data is proposed. Method of uniformity.
