1.Product Overview

1.1 Overview

Liquid boiling has different boiling modes according to the difference in heat flux density of the process. The membrane boiling that weakens the evaporation and the nucleate boiling that accelerates the evaporation, how to limit the heat flux density, and accurately control the boundary of the transition from membrane boiling to nucleate boiling, Preventing damage to the heating surface is an important issue faced in the experiment. The ZT0014 boiling heat transfer test bench is a training and teaching device for directly observing the process of liquid boiling and evaporation. The whole process is carried out in a transparent tank, and a condenser in the form of a water-cooled coil is set for temperature control of a closed loop. R1233ZD is used as the experimental liquid. Compared with water, its boiling point is lower, about 18°C, so that the entire experimental process can be carried out at a lower temperature and lower heating power. The cooling water flow, heating power, pressure and temperature of all relevant points are recorded through the sensors set in the closed circuit. The measured value is directly displayed on the display in digital form.
