Abstract

The invention relates to the technical field of strengthened heat transfer, in particular to a device for controlling the dropwise condensing heat transfer performance of a superhydrophobic surface bymeans of a sound field. The device comprises a shell; a dropwise condensing heat exchanger is arranged in the shell, a steam inlet is formed in the upper end of the shell, a condensed water outlet isformed in the lower end of the shell, a cooling water inlet and a cooling water outlet are formed in one side of the shell, the cooling water inlet is located above the cooling water outlet, and a sound is arranged on the other side of the shell and fixedly connected with the side wall of the shell; and the device further comprises a control module, an adjusting unit and a heat transfer performance detection unit, the control unit is connected with the adjusting unit, the adjusting unit is connected with the sound to enable the sound to generate a vibration which has the corresponding frequency and amplitude with a signal generated by the control unit, the vibration is loaded to the dropwise condensing heat exchanger, the heat transfer performance detected by the heat transfer performance detection unit is transmitted to the control unit in a signal mode, and the control unit adjusts the vibration signal frequency and amplitude of the sound.

Description

technical field [0001] The invention relates to the technical field of heat transfer enhancement, in particular to a device for controlling the heat transfer performance of droplet condensation on a superhydrophobic surface by using an acoustic field. Background technique [0002] Droplet condensation has aroused the interest of many researchers due to its high heat transfer coefficient, and has conducted extensive research on heat transfer mechanism, realization methods, and industrial applications (reducing equipment scale and reducing production costs). . However, most of the commonly used industrial equipment are metal materials with high surface free energy, which can be wetted by most liquids. To form droplet condensation on the metal surface, the metal surface must be modified (such as plating gold on the surface, Silver, rhodium, palladium and other precious metals) or use appropriate accelerators (hydrophobic organic accelerators such as oleic acid, mercaptan, mont...
