摘要
基于MATLAB 7.6开发了管壳式换热器,充分利用压降优化设计软件。通过改变换热器结构,充分利用管壳程压降,提高传热系数,减少换热面积。通过案例分析表明,充分利用压降后,换热器的传热系数提高了21%,换热面积减小了20%,大大减少了换热器的投资费用。
Making best use of pressure drop, the paper developed an optimizing design software for shell and tube heat exchanger based on MATLAB 7.6. By wtrying the structures of heat exchanger, fully u,ing of pressure drop between shell and tube gap can improve heat transfer coefficient and reduce heat exchange area. By analysis of the designed case, the results prove that the heat transter coefficient increases by 21% and the heat exchange area reduces by 20% thus the cost of heat-exchanger can be decreased greatly.
