A device and method for enhancing heat transfer of mist droplet evaporation

Abstract

The invention discloses a device and method for strengthening fog droplet evaporation heat transfer, which comprises a liquid storage tank, a controllable flow valve, a centrifugal pump, a booster fan, a feedback thermometer, an electric control cabinet and a heat transfer generator. The heat exchange generator includes a thermal insulation shell, an oscillating atomizing nozzle, a fixed plate and a bionic deflector. The liquid storage tank stores high-temperature liquid, and the liquid inlet pipe of the liquid storage tank guides the high-temperature liquid into the liquid storage tank. wherein, the outlet pipe of the liquid storage tank is connected to the oscillating atomizing nozzle through a centrifugal pump, and the controllable flow valve is arranged on the liquid outlet pipe between the liquid storage tank and the centrifugal pump to control the atomized liquid; The interior of the heat preservation shell is sealed, and the inside of the heat preservation shell is installed with a fixed plate and a bionic deflector in sequence from top to bottom. The bionic deflector is a thin plate with a spiral structure, and the surface of the bionic deflector is a bionic surface. ; The present invention is temperature-controllable, low resistance, fast heat transfer rate, small volume, small footprint and high gas evaporation efficiency.

Description

technical field [0001] The invention relates to the field of thermal energy engineering, and more specifically, to a device and method for enhancing evaporation and heat transfer of mist droplets. Background technique [0002] A heat exchanger (also known as a heat exchanger) is a device used to exchange heat between cold and hot media, and is widely used in many fields such as chemical industry, petroleum, power and food. In the field of thermal energy engineering, the exchange efficiency of heat exchanger directly affects the efficiency of thermal system or thermodynamic cycle system, thus affecting the utilization rate of energy. Energy shortage and environmental pollution have become one of the main problems restricting the sustainable development of human beings. Among them, how to improve the efficiency of energy utilization, heat exchangers have naturally become one of the equipment that people pay attention to. [0003] Heat exchangers include condensers, intercoole...
