For decades, researchers have been considering the possibility of using high-speed air jet to cool thermal electronic equipment. However, nowadays, air jet cooling system is not widely used. The two obstacles to its application are its complexity and heaviness. The air injection system must be made of metal in order to withstand the pressure of air injection at a speed of more than 200 mph. Moreover, the air treatment system is very complex, which is composed of many discrete components that manage the air flow and guide the air to the high temperature points that need to be cooled.

Using additive manufacturing technology, the researchers built an air jet cooling system in a single component that can guide high-speed air to high temperature points of multiple electronic devices. The researchers also built the cooling system out of solid polymer materials that can withstand the harsh conditions associated with high-speed air injection. The focus of this research is to heat the high-power electronic equipment. "High power electronic devices have serious thermal management problems and are used in many applications, especially in data centers, electric vehicles, aircraft, automobiles and off-road vehicles," said nenad Miljkovic, associate professor of mechanical science and engineering at the University of Illinois However, the application of high-power electronic equipment in electric vehicles, solar power generation systems, 5g communication and high-power computing systems using GPU is growing rapidly. The heat generated by electronic equipment in such systems must be dissipated so that the entire equipment can operate efficiently and reliably. Generally speaking, the higher the power is, the better the performance is. However, the higher the power is, the more difficult it is to dissipate heat. New cooling technology is needed to support the development of power system.
