Abstract
In the course of the work for experiments and efficiency studies, the previously developed unit was modified and experimental studies were carried out in the flow range from 0,4 to 1,15 l/s for heating and heated media for the design boiling point of the intermediate coolant in closed two-phase evacuated water-filled thermosiphons equal to 60 °C. It has . been established that the use of a thermal siphon in an inclined position is more effective for heat transfer. It is shown that the effect of inclination on the power of a thermosiphon heat exchanger depends on the boiling mode of the working £ fluid, maximum when operating in bubble boiling and minimum when operating in projectile and hypershell modes
