摘　　要：操作型换热器计算在换热器的设计中历来都是难点,其解决办法一般都采用试差法或传热单元法(图表法),缺点是计算过程繁锁、精度低。通过理论分析,推导出流体出口温度。结合计算机技术,其计算过程简捷,且精度高。The computation of the fluid outlet temperature in the operational heat exchanger has always been the thorny point in the design of the heat exchanger. The most commonly used solutions to this point are known as the trial and error method and the heat transfer unit method （charts）, which have the shortcomings in complex computation and low precision. Based on the theoretical analysis, the fluid outlet temperature has been inferred with the combination of the computer technology. The new computation is simple and direct, having high degree of precision.
