摘要

Effective thermal management is a key to ensure the normal operation and long-term stability of high-power equipment. Spray cooling technology demonstrates robust thermal management performance and enables efficient utilization of coolant. This study proposes a spray cooling system that integrated with color identification. Hardware and software design of a color distinguish device based on STM32F407 microcontroller is presented. The impact of different spray pressures and different nozzles of various size on heat transfer characteristics is evaluated. The result reveals that, as spray pressure increasing, the average temperature of heating surface decreases significantly. The results show that the maximum temperature is reduced by 5%, when spray pressure ranges from 3.0 MPa to 4.5 MPa. However, at the same cooling duration, higher pressure requires more injection cycles than lower pressure to avoid the emergence of dry-out points. The injection cycle is shortened by 18 s. The cooling effect of three aperture nozzles are compared. It was observed that increasing nozzle aperture size substantially improves cooling performance, while reducing injection interval time. With the increase of nozzle aperture, the maximum temperature is reduced by 18% and the injection cycle is shortened by 27 s.
