Simulation and Optimization of Heat Transfer Characteristics in Two-phase Region of Small Spray Cooling Unit

Long Huang, Yujiao Wang

Abstract


In this paper, the working principle and structure of the spray cooling device are introduced, and the Influence of spray height and flow rate on the heat transfer coefficient is discussed. The spray cooling device achieves the purpose of heat transfer and cooling by converting the liquid into small droplets and spraying on the surface to be cooled. The increase of spray height can enhance the heat transfer Effect, improve the contact time between the droplet and the surface, and increase the heat transfer coefficient. The increase of spray flow can increase the contact area between the droplet and the heat source, increase the heat transfer surface area, and then increase the heat fl ux. Spray cooling devices have wide application prospects in the fi elds of electronic equipment cooling and industrial production.
