Claim 0:
1. A high pressure, high temperature spray cooling system for heat transfer, the system comprising:
a supply tank having a heater and a high pressure pump;
a spray chamber spaced apart from the supply tank, the spray chamber having a workpiece receiving bed and a nozzle spaced apart from the workpiece receiving bed;
a supply line having a first supply line end and a second supply line end, the first supply line end connected to the supply tank and the second supply line end connected to the nozzle such that contents within the supply tank are supplied to the nozzle through the supply line at a high pressure to cool a workpiece on the workpiece receiving bed; and
a gas supply tank, a gas line having a first gas line end connected to the gas supply tank and a second gas line end connected to the nozzle,
wherein the gas supply tank contains nitrogen gas,
wherein the supply tank contains a liquid and nano-particles,
wherein the liquid is water, the nano-particles are copper nano-particles (CuNPs) or aluminum nano-particles (AlNPs), and the nano-particles are mixed in the liquid to form a homogenous suspension, and
wherein the workpiece is heated to a temperature of 600° C. to 1,100° C. and the high pressure pump that reaches pressures of up to 2.5 MPa.
