Based on the heat exchanger model with uneven distribution of fluid on one side, a mathematical model of the effect of non-uniformity of distribution on the performance of heat exchanger was established. Through theoretical analysis and calculation, in order to study the uneven distribution of the internal heat exchanger, Which provides an analytical method.This theoretical model includes two kinds of continuous models and discrete models, the former provides an analytical method for studying the drop of the heat exchanger performance caused by the uneven distribution of the logistics, and the latter provides a method for the control experiment The accuracy of the study provides a theoretical basis.The conclusions of the study on the optimal design of the heat exchanger is of great significance.
