N2 - The possibility is shown of measuring the temperature field, the droplets sizes, and the irrigation pattern of an impact surface during spray cooling with the use of high-speed IR thermography, video visualization, and a transparent design of the heating element. New experimental data on the heat transfer intensity are obtained. In particular, it is shown that the heat transfer coefficients during spray cooling are 1.5 times higher than the maximal heat transfer under multijet cooling regime. The liquid flow rate for the spray nozzle is lower by almost 5 times compared to the multijet nozzle.
