Abstract
Abstract A cooling means for dispensing the heat generated by atomic power plants or by any type of power generating unit using fossil fuel. Hot water (110*F) from a standard condenser is first put through a hydrojet device which mixes cool air (up to 80*F) with the water to form a type of emulsion. This mixture is then applied to a plurality of strip plates which are positioned in line with a stream of pre-cooled air (about 70*F). The water which drains from the strip plates (75*F) is recycled. The remainder of the water mixture is picked up by the air stream and blown through an exponential throat by power blowers and finally applied to a plurality of condensation vanes which are internally cooled by a liquid refrigerant. Normal air of 60 percent humidity and 90*F to 95*F temperature (wet bulb) is expelled into the ambient space and the condensed water is also recycled and sent back to the condenser unit.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
160 words
A heat exchanger for disposing of the heat present in water derived from a power plant condenser comprising: a hydrojet mixer for mixing the hot water from the condenser with ambient air to produce an emulsion-like mixture and for saturating the air in the mixture; a separation chamber adjoining the mixer for separating the water from the air in said mixture, said chamber including a set of strip plates for collecting the water in said mixture and for diverting it to a recycling trough, and a set of blowers for applying a stream of ambient air to the plates and for blowing saturated air from the chamber; and a condensation chamber including a plurality of refrigerated vanes for receiving the saturated air and for condensing the water in the air, a return water trough for collecting the water from the vanes for recycling in the condenser, and an exit port for directing the cooled and dehumidified air into the atmosphere.
Claim 2
Dependent Claim
160 words
A heat exchanger for disposing of the heat present in water derived from a power plant condenser comprising: a hydrojet mixer for mixing the hot water from the condenser with ambient air to produce an emulsion-like mixture and for saturating the air in the mixture; a separation chamber adjoining the mixer for separating the water from the air in said mixture, said chamber including a set of strip plates for collecting the water in said mixture and for diverting it to a recycling trough, and a set of blowers for applying a stream of ambient air to the plates and for blowing saturated air from the chamber; and a condensation chamber including a plurality of refrigerated vanes for receiving the saturated air and for condensing the water in the air, a return water trough for collecting the water from the vanes for recycling in the condenser, and an exit port for directing the cooled and dehumidified air into the atmosphere.
Claim 3
Dependent Claim
21 words
A heat exchanger according to claim 1 wherein said mixer is mounted under a reservoir containing hot water from the condenser.
Claim 4
Dependent Claim
50 words
A heat exchanger according to claim 1 wherein said mixer comprises a motorized rotary fan, positioned in a cylindrical casing, a conduit for introducing air into the casing, a plurality of holes in the conduit for the entrance of ambient air, and means for supplying hot water to the casing.
Claim 5
Dependent Claim
32 words
A heat exchanger according to claim 1 wherein said blowers each comprise a streamlined casing, a motor within the casing and a revolving head including a plurality of propeller blades secured thereto.
Claim 6
Dependent Claim
26 words
A heat exchanger according to claim 1 wherein said strip plates are mounted vertically and perpendicular to the flow of the ambient air from the blowers.
Claim 7
Dependent Claim
39 words
A heat exchanger according to claim 1 wherein said condensation vanes in the condensation chamber are mounted vertically, have a generally flat cross section and are positioned so that their widest dimension is parallel to the surrounding air flow.
Claim 8
Dependent Claim
36 words
A heat exchanger according to claim 1 wherein the water draining from the strip plates and the water draining from the condensation vanes are joined in a common conduit and returned to the power plant condenser.
Claim 9
Dependent Claim
33 words
A heat exchanger according to claim 7 wherein the water collected in said common conduit is cleaned in a water filter and then delivered to a water pump for delivery to the condenser.
Claim 10
Dependent Claim
46 words
A heat exchanger according to claim 1 wherein the separation chamber and the condensation chamber are joined by an exponential throat for expanding the cross sectional area of the saturated air moving between said chambers to aid in condensing the water vapor in the moving air.
Claim 11
Dependent Claim
43 words
A heat exchanger according to claim 1 wherein the ambient air drawn into the separation chamber by the blowers is first passed through an air filter and then through an air conditioner to reduce its temperature and to eliminate some of its moisture.
Claim 12
Dependent Claim
25 words
A heat exchanger according to claim 10 wherein the air applied to said hydrojet is also drawn through the air filter and the air conditioner.
Claim 13
Dependent Claim
51 words
A heat exchanger according to claim 1 wherein said hydrojet includeS an axial chamber for the mixing of air into the casing containing the hot water, said axial chamber connected to a source of dry cool air and formed with a plurality of spaced holes for the discharge of air streams.
