Abstract
The numerical methods of the determination of dynamic and static characteristics of the plate-type heat exchangers with the back-stream circuit of the motion of heat carriers have been considered. The numerical method was developed on the basis of implicit difference scheme. The data of multivariant computations of transient processes of the heat exchanger module are given taking into consideration the longitudinal heat conduction of the separation wall made of aluminum and steel. The stationary state of the heat exchanger and its performances are considered as the completion of the transient process. In the range of adopted values of the velocity and temperature of the flows and partition wall thickness the longitudinal heat conduction affects the parameters of the transient modes of heat exchanger operation; for the stationary states this influence is insignificant.
