摘要: 利用参数集结法建立了板翅式热交换器的动态数学模型,特点是引入平衡面“连续法”分析热交换器静、动态特性.通过与试验及数值法计算结果的比较,验证了参数集结法的准确性,并说明了平衡面“连续法”分析热交换器特性的特点.

Abstract: A dynamic model of plate - fin heat exchangers was studied. The dynamic mathematical model of heat exchangers was established by using the lumped parameter method, especially the theory of the equilibrium surface "continuous method" of analysing the static and dynamic characteristics of heat exchangers was introduced. The accuracy of the lumped parameter method was verified by comparing the results of the lumped parameter method and the numerical method and the test. The characteristics of the equilibrium surface "continuous method" of analysing heat exchangers were thus demonstrated.
