Concluding
In activity the criterions and algorithms for realization of complex optimization of a design of compact heat exchangers are set up, designed ground of perennial researches. The designed problem software package allows to conduct of projecting and verifying calculation of the compact laminated-ribbed heat exchanger. In particular, the algorithm of calculations allows to execute optimization of a design of the heat exchanger on three independent conditions: technological, thermal and exploitational efficiency. The experimental check affirming satisfactory functionability of the heat exchanger condenser is held the experimental data for calculation of thermal values and processes of heat and mass transfer are obtained at negative temperatures of a "cold" channel. The activity is of interest for the specialists engaging designing of compact laminated-ribbed heat exchangers, working on two phase heat carriers or hyperthermal heat-stressed conditions.
