Abstract
Spray cooling offers the ability to remove high heat fluxes. In this paper, experimental investigations on heat transfer in spray cooling with ammonia were conducted, using single pressure atomized nozzle in 2.5 cm × 1.2 cm test surface. Results demonstrate that ammonia is one of the best working fluid in spray cooling. It is exhibited that the heat fluxes could exceed 400 W/cm2 at the surface temperature of heat sink below 15°, and it is also shown that an increased CHF as the spray distance decreased. The maximum heat transfer coefficient values can reach up to 95000 W/(m2 · K).
