Экспериментальное исследование работы термосифонов, заправленных хладагентами

Abstract

The processes in the chamber of the thermosyphon on the experimental stand created at the Department of Industrial Heat Power Engineering and Ecology of the Educational Institution “Gomel State Technical University named after V.I. P.O.Sukhoi” were studied. The results of an experimental study of the operation of closed two-phase heat transfer devices filled with refrigerants R404A, R407C, R410A are presented. Experiments were carried out at angles of inclination of devices (0º, 90º), which increases the field of application of such heat exchange elements in industry. The range of supplied heat fluxes was 20-128 W, the surface temperature of the device varied within +18 … +63°С. The dependence of the thermal resistance of the thermosyphon on the supplied thermal load is established, and the analysis of the results obtained is carried out.
