Abstract

An evaporative cooler that includes a frame, a plurality of pads attached to the frame so that the pads substantially enclose an air space to be cooled, a water delivery device positioned at or near the top of the pads to wet the pads, a plurality of drain pans positioned at or near the bottom of the pads to collect water from the pads, and a fan to draw air through the wetted pads, thereby cooling the air by evaporation.

Claims

AMENDED CLAIMS received by the International Bureau on 08 May 2013 (08.05.2013) WHAT IS CLAIMED IS:
1. An evaporative cooler connected to an oil producing facility, comprising: a frame; a plurality of pads attached to the frame so that the pads substantially enclose an air space to be cooled, wherein the plurality of pads include a bottom pad and intermediate pads positioned above the bottom pad; a water delivery device for receiving water comprising oil from an oil production process and wherein said device positioned at or near the top of the pads to wet the pads; a plurality of drain pans positioned at or near the bottom of the pads to collect water from the pads, wherein drain pans associated with the intermediate pads are configured to deliver the collected water to a lower pad; and a fan to draw air through one or more of the wetted pads, thereby cooling the air by evaporation.
2. The evaporative cooler of claim 1, wherein the cooler is configured to recycle the collected water for reuse.
3. The evaporative cooler of claim 1, wherein the frame has a horizontal face, and the fan is configured to expel the cooled air through the face and out of the cooler.
4. An air cooling bank comprising a plurality of evaporative coolers wherein one or more coolers is as claimed in claim 1, wherein the evaporative coolers are connected together and configured to run simultaneously, thereby increasing the amount of air cooled.
5. The evaporative cooler of claim 1, wherein the water delivery device is a plurality of pipes positioned adjacent the top of the pads.
6. The evaporative cooler of claims 1 or 5, wherein the pipes have apertures configured to release water from the pipes onto the pads.
7. The evaporative cooler of claim 1, wherein the water is contaminated with at least 2 percent oil.
8. The evaporative cooler of claim 1, wherein the drain pans associated with intermediate pans are configured to collect water that drains from the bottom of the intermediate pad directly above each drain pan, and deliver that water to the top of the next lower pad.
9. The evaporative cooler of claim 1, wherein the drain pans associated with bottom and intermediate pads comprise: raised sides to enclose a trough; a raised first end that slopes to a depressed second end; and an aperture that permits water to exit the trough of the drain pan, wherein the water enters the top of the next lower pad.
10. The evaporative cooler of claim 1, wherein the plurality of pads are removable from the frame.
11. A method of cooling air, comprising: providing a plurality of cooling pads stacked one on top of the other and substantially enclosing an air space to be cooled; receiving water extracted with oil during an oil production process; wetting the cooling pads with the water at an upper portion thereof; and pulling ambient air through the wetted cooling pads and into the air space to be cooled.
12. The method of claim 11, further comprising collecting excess water for reuse after it passes through the cooling pads.
13. The method of claim 11, further comprising receiving water contaminated with at least 2% oil.

Claims 1 and 9 are amended to better claim the invention by adding features of the use of the evaporative cooler in connection with an oil producing facility.

Claims 16-20 are added. New claims 16-19 depend from independent claim 1. New claim 20 depends from independent claim 9.

Claims 1-4 and 6-10 are rejected as lacking novelty over US 2011/074051 (hereinafter "Dl"), FR 2,641,853, (hereinafter "D2"), US 5,289,696 (hereinafter "D3"), US 4,045,523 (hereinafter "D4") and EP 1,541,932 (hereinafter "D5"). Applicant submits that D1-D5 do not anticipate or render obvious the combination of features of amended claims 1- 4 and 6-10 as described above.

In view of the amendments to claims 1-15, Applicant believes the amended claims to be novel and unobvious. Therefore, a favorable preliminary written examination report is respectfully requested.
