Résumé

In a wind tunnel it is executed carefully planned regular and an experimental research of influence on heat aerodynamic characteristics of the basic geometrical parameters of rectangular ducts of plate-fin (PFT) exchange surfaces (HTS) with high value of finning f = 14. Criteria and graphic dependences are recommended for calculation of heat transfer and aerodynamic resistance of heat exchangers. The graphic method of definition and supervision of continuous change of values of the current estimations of a rational enhancement of convective heat exchange (RECH) and necessary at designing of heat exchanger duct values PFT HTS is offered within the limits of all area of realization of process RECH. The opportunity of reduction practically up to 2.78 times of volume and weights of a core of heat exchangers with interrupted ducts instead of smooth ones is proved.
