Study of jet cooling on disk laser

In order to analyze the effect of jet cooling technology on thin disk laser, starting from the turbulent heat transfer theory, we define two parameters ha and the average maximum temperature difference for evaluation of jet cooling heat transfer capacity and cooling uniformity. Using the ANSYS CFX fluid dynamics simulation software, a physical model of jet cooling was built, and the multiple jet plate structure was calculated. Furthermore, the entire jet cooling experimental device was designed, and heat source jet cooling was simulated. The results show that jet cooling heat transfer capacity and cooling uniformity are mainly affected by the structural parameters of jet plate, and ANSYS CFX calculation results can be used to guide the optimization design of the structure parameters of jet plate.
