Patent ID: 8020399

Claim:
A flash evaporation cooling system, comprising: a conventional fan of the type having a power source, a frame and having fan blades carried on a rotatable shaft of a motor; an eccentric attached to the rotatable shaft, wherein the eccentric rotates as the shaft rotates; a fluid loop including a water pump, a water pump high pressure water outlet, at least one mister nozzle, a high pressure relief valve for receiving recycled water from the at least one mister nozzle and an inlet pressure relief valve said water pump mounted on the frame in proximity to the rotatable shaft and comprising a pump body housing a pump bore, a pump piston and a spring carried within the bore, a seal between the pump piston and the bore, and a pump piston shaft extending from the bore and exiting externally from the pump body, wherein the externally protruding aspect of the pump piston shaft is in continuous contact against a bearing on the outer surface of the eccentric, the pump shaft and piston reciprocating in an eccentric manner as the fan shaft rotates, and wherein said pump body further comprises a water inlet/outlet, wherein the water inlet/outlet pressure and the spring provide force to hold the piston against the bearing on the down stroke; said at least one mister nozzle coupled to the water pump high pressure water outlet, and positioned to emit atomized water mist near the fan blades; said inlet pressure relief valve in the pump body having a first water inlet in communication with a water supply, a second inlet in communication with the high pressure relief valve and a water outlet in fluid communication with the pump bore to supply the pump with water and to recycle excess water back to the pump.
