Abstract
Abstract A spray cooling system employing a pump and spray heads in a flowing stream of water. Baffles are provided in the stream to insure that the hot surface water will not flow past the pump without being forced through the spray heads. Openings are provided through the lower portions of the baffles well below the level of the pump intake.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
A system for cooling water in a continually flowing stream having a layer of relatively hotter water at the surface of said stream, said system comprising: a plurality of pumps having their intakes located in said stream in spaced relation to one another; a plurality of water spray heads connected to the discharge of said pumps to receive the hotter water therefrom and spray said water into the atmosphere above the stream to cool same; and baffle means positioned in said stream defining a pump area and a spray head area, said baffle means prohibiting the flow of said hotter surface water from bypassing said pump intakes.
Claim 2
Independent Claim
107 words
A system for cooling water in a continually flowing stream having a layer of relatively hotter water at the surface of said stream, said system comprising: a plurality of pumps having their intakes located in said stream in spaced relation to one another; a plurality of water spray heads connected to the discharge of said pumps to receive the hotter water therefrom and spray said water into the atmosphere above the stream to cool same; and baffle means positioned in said stream defining a pump area and a spray head area, said baffle means prohibiting the flow of said hotter surface water from bypassing said pump intakes.
Claim 3
Dependent Claim
45 words
The system set forth in claim 1 and further comprising walls defining an opening through said baffle means to connect said pump and spray head areas in water communication and wherein the intakes to said pumps are located above said openings through said baffle means.
Claim 4
Dependent Claim
30 words
The system set forth in claim 2 wherein the intakes to said pumps are located closer to the surface of said water than to said openings through said baffle means.
Claim 5
Dependent Claim
41 words
The system set forth in claim 2 wherein the capacities of said pumps are greater than the flow of hotter water thereto thereby insuring a recirculation of said water from said spray head area through said opening to said pump area.
Claim 6
Independent Claim
129 words
A system for cooling water in a continually flowing stream having a layer of relatively hotter water at the surface of said stream, said system comprising: a pump having its intake located in said stream; at least one water spray head connected to the discharge of said pump to receive hotter water therefrom and spray said water into the atmosphere above the stream to cool same; and baffle means positioned in said stream defining a pump area and a spray area, said baffle means prohibiting the flow of said hotter surface water from bypassing said pump intake, said baffle means including walls defining an opening therethrough connecting said pump and spray head areas in water communication said intake to said pump being located above said opening through said baffle.
Claim 7
Independent Claim
129 words
A system for cooling water in a continually flowing stream having a layer of relatively hotter water at the surface of said stream, said system comprising: a pump having its intake located in said stream; at least one water spray head connected to the discharge of said pump to receive hotter water therefrom and spray said water into the atmosphere above the stream to cool same; and baffle means positioned in said stream defining a pump area and a spray area, said baffle means prohibiting the flow of said hotter surface water from bypassing said pump intake, said baffle means including walls defining an opening therethrough connecting said pump and spray head areas in water communication said intake to said pump being located above said opening through said baffle.
Claim 8
Dependent Claim
29 words
The system set forth in claim 5 wherein said pump inlet is located as close as possible to the surface of said stream without drawing air into said pump.
