Abstract
Abstract A water cooling system wherein collapsible cooling towers are supported above the body of water to be cooled. The cooling towers are composed of collapsible side walls which extend under the influence of the pressurized water being supplied thereto. A plurality of baffles are provided about the upper end of the extended towers and the water supplied to the towers flows over the baffles which divides the water into droplets thereby cooling the water.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
A system for cooling a body of liquid, comprising in combination: a liquid discharge member including an inlet end and an outlet end wall, selectively extendable and collapsible side walls joining said ends constructed and arranged such that the weight of said side walls and said outlet end wall will cause said member to collapse; means supporting said liquid discharge member above said body of liquid; liquid Pressurizing means; means connecting said liquid pressurizing means to said inlet end of said liquid discharge member; and walls defining a liquid discharge opening through said outlet end wall, said discharge opening being of a predetermined size such that said liquid cooling member will extend substantially vertically above said body of liquid under the influence of the pressurized liquid supplied thereto and the liquid will flow from said discharge opening and fall back to said body of liquid and in the process be cooled.
Claim 2
Independent Claim
151 words
A system for cooling a body of liquid, comprising in combination: a liquid discharge member including an inlet end and an outlet end wall, selectively extendable and collapsible side walls joining said ends constructed and arranged such that the weight of said side walls and said outlet end wall will cause said member to collapse; means supporting said liquid discharge member above said body of liquid; liquid Pressurizing means; means connecting said liquid pressurizing means to said inlet end of said liquid discharge member; and walls defining a liquid discharge opening through said outlet end wall, said discharge opening being of a predetermined size such that said liquid cooling member will extend substantially vertically above said body of liquid under the influence of the pressurized liquid supplied thereto and the liquid will flow from said discharge opening and fall back to said body of liquid and in the process be cooled.
Claim 3
Dependent Claim
46 words
The system set forth in claim 1 and further comprising baffles connected to said discharge member constructed and arranged to cause the liquid flowing from said discharge opening to flow over said baffles and divide same into droplets to aid in the cooling of said liquid.
Claim 4
Dependent Claim
26 words
The system set forth in claim 1 wherein the surface area of said outlet end wall is substantially larger than the cross-sectional area of said inlet.
Claim 5
Dependent Claim
19 words
The system set forth in claim 3 wherein said member is hyperbolic in shape when in the extended position.
