Effects of Spray Angle on Spray Cooling of Extruded Aluminum Alloy Plate

Spray cooling technology relying on phase-change mechanism has a notable ability to remove high heat fluxes. Spray cooling can be used to transfer large amounts of energy through the latent heat of evaporation. Heat transfer rates much higher than can be attained in pool boiling are possible with spray cooling since the vapor can be removed from the surface more easily. Therefore, spray cooling has a number of applications in the various fields such as continuous casting process, electronics thermal control and metal quenching process which require a high flux cooling technique [1–3]. One important area which would benefit from spray cooling to improve heat removal is press quenching of extruded aluminum alloy plate.
