摘要 采用集总参数法,基于"微元段"方法,推导了单个"微元段"换热器内参数的变化。建立了1,4,9,100"微元段"空气叉流换热器仿真模型,并对模型稳态计算误差及其影响因素进行了分析。为了简化叉流换热器仿真计算算法,提高仿真计算速度,同时改善模型计算精度,提出了一种简化的换热计算模型,并基于该模型进行仿真研究。研究结果发现:简化的换热计算模型准确度高,模型算法简单,可广泛应用于叉流换热器仿真计算。 Based on cell concept, the lumped parameter method was applied and the parameters in single heat exchanger cell were deduced. Thereafter 1, 4, 9,100 cells heat exchanger simulation model was set up and the simulation error and its influencing factors were analyzed. To simplify the algorithm and increase the calculation speed, as well as improve the accuracy of cross flow heat exchanger, the simplified heat exchanger model was proposed and reviewed. The research results show that the calculation of simplified heat exchanger is precise and the algorithm is simple. The model could be widely applied in cross flow heat exchanger computation.
