摘要/Abstract

摘要： 建立了基于分排参数模型的数字化设计算法，以实现圆柱型直通表冷器的数字化设计与计算分析.模型在热力学、传热学的基础上，采用二分法进行迭代计算.利用建立的算法模型对不同制冷工况下的圆柱型直通表冷器进行设计计算，并与平面翅片管表冷器(总换热面积相等)的试验数据进行了比对分析.结果表明，对于循环风量和进出水温差一定的设计模式，标准工况下的圆柱型直通表冷器能提供更大的冷量；减小进水温度对换热影响作用不明显，而当提高进风温度，平面翅片管表冷器有更好的换热效果.计算同时得到了各排换热管的冷量分布规律，靠近进风、圆弧直径较小的换热管其换热性能更好，冷量更大.

Abstract: For the purpose of digital design and calculation of cylindrical straight-through heat exchanger, design model based on sub-row-parameter model is established. The dichotomy iteration, based on thermodynamics and heat transfer theory, is employed. Model calculated results of cylindrical heat exchanger in different cooling conditions were compared with the experimental data of fin-tube heat exchanger. The results show that total cooling capacity of cylindrical heat exchanger is higher in standard condition. The reduction of water inlet temperature don’t have obvious impact on heat transfer while fin-tube heat exchanger will provide larger cooling capacity with the increase of air inlet temperature. The cooling capacity distribution of each row of tubes is also studied through calculation: the tubes with smaller diameter, which are closer to the air inlet, have better heat exchange performance and higher cooling capacity.

Key words: cylindrical straight-through heat exchanger; sub-row-parameter model; digital design
