Title Spray cooling system of high-temperature parts design
Abstract
Due to the higher demand for cooling heat exchanger in various sectors, the heat transfer problem has become Key bottlenecks in some sectors. Therefore people urgently need to find a new type of heat exchanger to address the demand for high heat flux heat transfer. One of the most potential in the new heat exchanger is the spray cooling heat exchanger way. In addition, people gradually pay attention to some of the advantages of the spray in the infrared stealth.
According to the rapid spray cooling requirements, experimental setup is designed and built. The experiment focuses on spray height and angle of the nozzles, entrance pressure, flow, and other major factor in the experimental analysis, and a simple analysis of the heat transfer mechanism. In the experiment, the effect of the infrared stealth about spray cooling and the shelter of spray is analyzed .Compared the spray cooling to the shelter of spray, simple spray shelter is difficult to quickly reach Infrared Stealth effect on the surface of about 80 ℃.But the combination of spray cooling and the shelter of spray can achieve a good stealth effect.
