Experimental study of heat transfer characteristics and energy consumption of spray cooling

Spray cooling has been widely used to dissipate heat in high heat flux situations such as electronic chips. In this study, a spray cooling experimental system was built to study the spray cooling characteristics and energy consumption in the two-phase region. The experimental results show that the critical heat flux can reach 300.2 W/cm2 at a height of 28 mm; reducing the spray height can increase the critical heat flux, but the system energy consumption also increases. The obtained results have certain guiding significance for the optimization of spray cooling applications.
