In the basis of algorithm of the program there is used. the designed two dimensional mathematical model of calculation of heat transfer in the cross-precise compact plate-ribbed heat exchanger, consisting of a system of differential equations of energy for hot and cold heat carriers and equations of heat transfer. The solution of system is implemented by the numerical method, for what the system of differential equations was exchanged with the help of method of finite differences by grid equations on a grid 10x10… 40x40 of clusters. The calculation of heat transfer thus was executed sequentially for each elementary site ⊿x⊿y before obtaining with given accuracy in 0.01℃ of values of temperatures of a wall, cold and hot heat carrier. The model allows heat and mass transfer in cold and hot channels (with allowance for heat and mass transfer in a boundary layer) and feature of heat transfer on initial segments of channels, according to designed earlier to techniques [4]. As a result of calculations the two dimensional. fields of temperatures of hot,cold heat carrier and heat-transport surface on a grid with demanded accuracy were determined.
