Boiling Heat Transfer Unit

The Boiling Heat Transfer test bench is a training and teaching device for directly observing the process of liquid boiling and evaporation. 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 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. Liquid boiling has different boiling modes according to the difference in heat flux density of the process. 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 measured value is directly displayed on the display in digital form. The cooling water flow, heating power, pressure and temperature of all relevant points are recorded through the sensors set in the closed circuit.

 

Features: 

The transient data during the change of the workbench is directly displayed on the display in digital form.

The test bench is equipped with a condenser in the form of a water-cooled coil to control the surface temperature of the closed loop temperature.

The whole experiment process of boiling heat transfer test bench is carried out in a transparent experiment tank, and the process is clear and easy to observe.

The various physical quantity data of the workbench change process can also be transmitted to the PC through the USB interface for further processing.
