Research of heat transfer in the compact heat exchanger working on twophase heat carriers

The analytical investigation is executed by a numerical modeling pf the heat and mass transfer in the heat exchanger - condenser. For this purpose the two dimensional model of calculation of heat transfer ii! the cross - precise compact plate-ribbed heat exchanger designed. The model allows the heat and mass transfer in cold and hot channels and heat rejection on initial segments of channels. The reliability of model is checked by matching the computational mean and local data with the experimental heat exchanger. The qualitative and quanti exchanger. The qualitative and quantitative consent with experiment is obtained. The numerical research is executed in more broad band of parameters. The pacing factors influential in increase of heat transfer in the heat exchanger are installed. The fields of temperatures of a heat-transport surface and heat transfer mediums are researched at different regime parameters. Are offered anti-iceing measures averting freezing of the condenser.
