  • Abstract The purpose of this experiment is to use the piezoelectric atomizer film as a nozzle, set up a high-power electronic devices (≥ 100W COB LED) based micro-spray cooling system to study the different experimental parameters under the conditions of this micro-spray cooling system of various physical phenomenon. In this experiment, the spray velocity, spray particle size and temperature were measured, and the advanced optical measurement system (μPIV, μIPI, LIF and IR detector) was used as the main measurement tool. The experimental parameters of the micro-spray cooling system were changed during the measurement, such as porcelain diameter, mass flow rate, heat flux and spray distance, to discuss the effect of heat dissipation on electronic devices, while observing the change of trajectory and particle size of atomized droplets during flight and study their physical phenomena.
