DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(7) As discussed above, embodiments of the present invention relate to a pre-evaporative system for use with an evaporative cooling apparatus that utilizes fresh water to control a buildup of mineral deposits in the apparatus. A description of an evaporative cooling apparatus that utilizes fresh water to control a buildup of mineral deposits in the apparatus can be found in U.S. Pat. No. 6,367,277, the disclosure of which is incorporated entirely herein by reference. The pre-evaporative system enhances the function of the evaporative cooling apparatus shown in U.S. Pat. No. 6,367,277, which is incorporated entirely herein by reference.

(8) As shown in FIGS. 1-4, a pre-evaporative system 10 may include a pre-evaporative media 20, a cooling media 30, and a shield 40 with a mounting plate 46. The pre-evaporative media 20 may include a cellulose fiber or synthetic fiber pad 22 with an edge coating 24 and further may include a first distribution plate 26 coupled to the pre-evaporative media 20. The cooling media 30 may include a cellulose fiber or synthetic fiber pad 32 with an edge coating 34 and further may include a second distribution plate 36 coupled to the cooling media 30. The shield 40 with mounting plate 46 operates to retain the pre-evaporative media 20 and the cooling media 30 in a position adjacent one another. The shield 40 also forms a seal with the respective first and second distribution plates 26 and 36. The shield 40 provides these function above, while also shielding a first and second water distribution pipes 42 and 44 respectively. For example, and without limitation, an edge 28 of distribution plate 20 extends at an angle, such as an 80 degree angle, and an edge 38 of distribution plate 30 extend at an angle, such as an 80 degree angle. (See FIG. 2) The shield 40 has an edge 49 that engages the angled edge 38 of the distribution plate 30 and the mounting plate 46 is coupled to the shield 40 on a side opposite the edge 49 with couplers 48 and engages the angled edge 28 of the distribution plate 20, thereby forming a seal along the distribution plates of the pre-evaporative media 20 and the cooling media 30 to divert all water to the pre-evaporative media 20 and the cooling media 30. (See FIG. 2) This configuration of components allows for a smaller air tunnel height saving space and cost.

(9) By splitting the media of an evaporative cooling apparatus into a pre-evaporative media 20 and a cooling media 30, cost for replacement may be reduced by ⅔. Further, having a pre-evaporative media 20 and a cooling media 30 allows for much higher cycles of concentration and less water consumed in flush down.

(10) As shown in FIGS. 1 and 3, the first distribution plate 26 coupled to the pre-evaporative media 20 may be a built-in distribution plate that diverts water evenly over the entire surface of the pre-evaporative media 20 and the second distribution plate 36 coupled to the cooling media 30 may be a built-in distribution plate that diverts water evenly over the entire surface of the cooling media 30. The operation of first and second distribution plates 26 and 36 eliminate the need for a distributer section of the evaporative cooling apparatus.

(11) Referring to FIG. 4, the first and second distribution plates 26 and 36 also operates to engage a removal tool 50 of the pre-evaporative system 10. The mounting plate 48 may be uninstalled from the shield 40, exposing the first distribution plate 26 coupled to the pre-evaporative media 20. The removal tool 50 may include a channel 52 that can engage the edge 28 of the first distribution plate 26 such that the edge 28 is inserted within the channel 52. The removal tool 50 may be pulled and the force applied to the tool pulls the pre-evaporative media 20 away from the cooling media and the shield 40 to be removed. In a similar manner, the cooling media 30 may be removed. The removal tool 50 in combination with the other unique elements of the pre-evaporative media 20, the cooling media 30 and the shield 40 with mounting plate 48 provide a unique pad removal system allowing the quick and efficient replacement of the loaded media 20 and 30.

(12) Referring to FIG. 5, depicted is a method 100 of using a pre-evaporative system used with an evaporative cooling apparatus. The method 100 comprises retaining a pre-evaporative media and a cooling media of the system adjacent each other and between a shield and a mounting plate in response to removably coupling the shield to the mounting plate (Step 101); forming a seal between the first distribution plate and the shield in response to removably coupling the shield to the mounting plate (Step 102); forming a seal between the second distribution plate and the shield in response to removably coupling the shield to the mounting plate (Step 103); and shielding a first water distribution pipe and a second water distribution pipe extending between the shield and the first distribution plate and the second distribution plate in response to removably coupling the shield to the mounting plate (Step 104).

(13) The method may also comprise uncoupling the shield and the mounting plate; engaging a removal tool with one of an edge of the first distribution plate or an edge of the second distribution plate; applying a force to the removal tool away from the pre-evaporative media or the cooling media to apply a force to the first distribution plate or the second distribution plate respectively; and removing the pre-evaporative media or the cooling media from the shield in response to applying the force to the removal tool.
