Abstract
Abstract A portable auxiliary cooling tower which is transportable over-the-highway for temporary or permanent use at a desired site. The tower is typically constructed on a trailer frame and is designed to provide maximum air flow for maximum cooling to temporarily replace or supplement larger fixed cooling tower cells. Another use of the portable cooling tower is to aerate stock ponds, chemical holding ponds and the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
193 words
A portable auxiliary cooling tower for performing cooling and aerating of liquids comprising: (a) a housing having shape and size compatible for movement with traffic along the highways without disassembly, air intake ports along each side of the housing, air outlet ports along the top of the housing, a frame member for supporting the housing and a plurality of wheels axially supported by the frame suitable for movement along the highways; (b) a plurality of closely spaced blowers carried within an upper portion of the housing for pulling outside air through the intake ports and expelling the air through the outlet ports; (c) packing provided within the housing between the inlet and outlet ports for filming the liquid being cooled and aerated; (d) a liquid distribution system for pulling liquid into the housing and distributing the liquid to the packing; (e) drift eliminator means provided in the outlet ports for stripping liquid from the air after it has passed through the packing; (f) liquid expulsion system for removing the cooled aerated liquid; and (g) leveling means carried by the frame and contactable with the ground for leveling and adjusting elevation at the site.
Claim 2
Dependent Claim
193 words
A portable auxiliary cooling tower for performing cooling and aerating of liquids comprising: (a) a housing having shape and size compatible for movement with traffic along the highways without disassembly, air intake ports along each side of the housing, air outlet ports along the top of the housing, a frame member for supporting the housing and a plurality of wheels axially supported by the frame suitable for movement along the highways; (b) a plurality of closely spaced blowers carried within an upper portion of the housing for pulling outside air through the intake ports and expelling the air through the outlet ports; (c) packing provided within the housing between the inlet and outlet ports for filming the liquid being cooled and aerated; (d) a liquid distribution system for pulling liquid into the housing and distributing the liquid to the packing; (e) drift eliminator means provided in the outlet ports for stripping liquid from the air after it has passed through the packing; (f) liquid expulsion system for removing the cooled aerated liquid; and (g) leveling means carried by the frame and contactable with the ground for leveling and adjusting elevation at the site.
Claim 3
Dependent Claim
64 words
An auxiliary cooling tower as set forth in claim 1 wherein the air intake ports comprise at least one louver panel along each side of a lower portion of the housing, each said louver panel being hinged for selected outward opening when in use and being retractable against the housing to form a part of the housing when the tower is not in use.
Claim 4
Dependent Claim
46 words
An auxiliary cooling tower as set forth in claim 2 wherein each louver panel is hinged along the bottom thereof, said panel being openable to a selected desired position to shield against the introduction of dust and debris from the ground around the auxiliary cooling tower.
Claim 5
Dependent Claim
30 words
An auxiliary cooling tower as set forth in claim 3 wherein the louver panels are shorter than the height of the air intake ports to leave a gap when closed.
Claim 6
Dependent Claim
65 words
An auxiliary cooling tower as set forth in claim 2 and including a plenum chamber in communication with the air intake ports through said louver panel and an elongated vertically disposed windbreak panel extending the entire length of said plenum chamber and being centrally located therein for eliminating loss of water and cooling efficiency by preventing high cross winds from traveling through said plenum chamber.
Claim 7
Dependent Claim
66 words
An auxiliary cooling tower as set forth in claim 1 and including a pair of oppositely disposed sidewall front and rear extension panels carried by the top of the housing and hinged around the periphery of the top of the housing to prevent re-circulation of the outlet air back into the intake ports and for effectively extending the height of the cooling tower while in use.
Claim 8
Dependent Claim
35 words
An auxiliary cooling tower as set forth in claim 6 wherein the extension panels are foldable to cover the entire top of the housing when not in use and when the tower is being transported.
Claim 9
Dependent Claim
66 words
An auxiliary cooling tower as set forth in claim 1 wherein the liquid expulsion system comprises a basin in the bottom of the housing and at least one gravity outlet sump located in the lowest most part of the basin and wherein said leveling means comprise a plurality of vertically movable locks for positioning the elevation of the housing and outlet sump to a liquid source.
Claim 10
Dependent Claim
50 words
An auxiliary cooling tower as set forth in claim 8 wherein the gravity outlet sump comprises a recessed cavity located at each end of the basin and being connectable to flexible liquid outlet hoses, said outlet sump comprising one or more outlet ports in the bottom of the recessed cavity.
Claim 11
Dependent Claim
78 words
An auxiliary cooling tower as set forth in claim 1 wherein the liquid distribution system comprises a liquid pump, flexible inlet hose, means for connecting the hose to a source of liquid to be cooled and aerated, a plurality of spray nozzles above the packing, and distribution header means for routing the liquid to the nozzles, said distribution header being longitudinally positioned below the packing for effecting precooling of the liquid prior to movement thereof to the nozzles.
Claim 12
Dependent Claim
64 words
An auxiliary cooling tower as set forth in claim 1 wherein the drift eliminator means comprises a plurality of longitudinally arranged blades, the upper portion of each of the blades being transversely offset from the lower portion so that the air flow is directed to one side off the vertical for directing the exhaust air from the outlet ports upwardly and to one side.
