Abstract

Results of studies of heat transfer in flat long-run channels in transient conditions of liquidflow are considered. Methods of the experiments and generalization of experimental data are described. Based on the obtained calculation relationship an easily knock-down liquid heat exchanger with heat load up to 40kW was designed. The design of the compact system of refrigeration of powerful gas lasers as used in scientific research, in holographic installations and also in medical apparatuses for diagnostics and photodynamic therapy of some oncological diseases is presented.
