摘要：
The heat transfer in plate heat exchangers with cross flows of heat-transfer media is considered. At constant values of thermophysical parameters using a model of a one-dimensional flow in cach channel, analytical expressions for the temperature and heat flux distributions are obtained. The efficiency of heat exchangers at different values of dimensionless parameters is estimated. A model is proposed to take into account the two-dimensional flow of heat-transfer media in channels on the basis of empirical relations for the flow resistance and the heat transfer in flat channels.
