摘要
本文通过一个实例,详细计算了换热器在产生温度交叉后的传热效果,并由热容量比和温度效率两参数推导出了温度交叉产生的条件,指出在将单程顺流或逆流型换热器改为多程时应充分注意这种温度交叉现象。
The heat transfer effects are described detailly for a exchanger with temperature cross, and the conditions causing temperature cross are derived by heat capacity ratio and temperature efficiency, it is pointed out that this phenominia should be paid close attentions to when a multipass exchanger is used to displace a single-pass parrallel or counterflow one.
