Title: Cooling device

Description:
BACKGROUND 
     Building spaces, such as office spaces, restaurants, auditoriums, warehouse areas, and manufacturing shop floors may require cooling systems to provide comfortable temperature and humidity levels to individuals who are occupying those particular building spaces. However, these existing systems may not be able to provide sufficient cooling and may require multiple cooling systems or a combination of cooling systems to provide a comfortable environment. 
     Outdoor areas, such as patio areas for restaurants, may also use cooling systems such as fans and evaporative coolers. However, these existing systems may not be able to provide sufficient cooling and may require multiple cooling systems or a combination of cooling systems to provide a comfortable environment.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. 
     Systems, devices, and/or methods described herein may allow for a cooling device (e.g., a device or a collection of devices) to provide a reduction to air temperature within a particular area/space. In embodiments, the device may include a fan which operates with an evaporating cooling system to reduce air temperature. In embodiments, the installation of the cooling device may reduce the need for multiple cooling systems to condition the same amount of area. For example, a patio area of a restaurant may require a single cooling device, instead of multiple cooling devices, to reduce the air temperature level and allow restaurant customers to sit in an area with a cooler temperature level. 
       FIG. 1A  describes an example of an individual sitting in an outside (e.g., an exterior area outside a building) patio area. To provide the comfortable temperature levels desired by the restaurant customers, the restaurant may have to install an outdoor ceiling fan  101  which circulates air from above the fan. However, since the ceiling fan only moves air, the ceiling fan is limited in how much cooling it can provide to the restaurant customers sitting in the patio area. Thus, the restaurant owners may also have to install evaporative cooling systems  102  which can be placed on ground. Evaporative cooling systems  102  may be able to cool the air temperature in the patio area, but they generate an airstream that includes a mist (e.g., haze, fog like appearance, etc.) into the patio area. While the comfort level in the patio area may be improved, the additional systems take up additional space on the patio area floor. As such, the restaurant owners are spending additional money on the evaporative coolers and also losing money because there is less patio space for additional customers. Furthermore, as the additional evaporative coolers are mechanical devices, the evaporative coolers are not aesthetically pleasing to view and, thus, reduce the enjoyment experience of the restaurant customers. 
     In contrast, the device and/or systems described herein overcome the deficiencies shown in  FIG. 1A . As shown in  FIG. 1B , cooling device  200  is attached to the ceiling of the patio area and provides cooling to the patio area. Since cooling device  200  incorporates evaporative cooling systems, it is unnecessary to install the multiple cooling systems described in  FIG. 1A . As shown in  FIG. 1B , air initially enters cooling device  200  from the sides of cooling device  200  and not from above cooling device  200 . In contrast, in this example, ceiling fan  101  obtains air from above ceiling fan  101 . Thus, as shown in  FIG. 1B , there are no evaporative coolers taking up valuable patio flooring space. Instead, the restaurant owner, in this example, can now place decorative plants that improve the visual experience of the patio area. Furthermore, the air that is supplied by cooling device  200  does not include any visible mist, hazy, or fog-like appearance.  FIG. 1C  shows cooling device  200  as attached to a side wall instead of the ceiling. While not shown, instead of connecting directly to a ceiling or wall, cooling device  200  may connect from a structure that connects to a ceiling or wall. Furthermore, cooling device  200  may connect at an angle to a part of a building structure (e.g., ceiling, wall, etc.). 
     Thus, restaurant customers are able to enjoy the experience of eating in a temperature controlled patio area without the need to place multiple mechanical devices within the restaurant customer&#39;s surroundings. Furthermore, the restaurant owner, another type of business, or a residential user, does not have to: (i) purchase and use different types of cooling systems at the same time, (ii) maintain different types of cooling systems, and/or (iii) sacrifice valuable commercial or residential space for mechanical equipment. While the cooling device, or systems, have been described within the context of a restaurant, the cooling device (e.g. cooling device  200 ) may be used in other types of settings, such as in a residential home, interior spaces, other types of exterior spaces (e.g., picnic areas, outside work areas—farming activities, etc.), and/or any other space that may require a cooling device. 
     As a result, cooling device  200 , provides desired temperature levels without having to install multiple different devices, such as fans, evaporative coolers, and/or other types of cooling devices for the same area to be cooled. Furthermore, cooling device  200  does not generate any supplied air with mist, haze, a fog-like appearance, etc. Because multiple different types of devices are not installed, there is a reduction in costs associated with purchasing and maintenance. Instead, one or more cooling devices  200  can be purchased and used to provide the desired temperature levels. Furthermore, the reduction in other types of devices may also increase the flooring area to install decorative products (e.g., plants, statues), tables, barbeque system, manufacturing machines, and/or other items. 
       FIG. 2  is a diagram of example cooling device  200 .  FIG. 2  shows fan  202 , cover  204 , trough  206 , connector  208 , and pad  302  which is described in later figures. 
     Fan  202  may be a device that rotates in a circular or elliptical fashion. In embodiments, fan  202  may have one or more blades, which extend from a central hub of fan  202 , that rotate when mechanical power is provided to fan  202  via the central hub which may include a motor (e.g., electrical, mechanical, etc.) to rotate the one or more blades. While blades are described, the blades may also be known as paddles or by any other name. In embodiments, fan  202  may force, i.e., push, air in a particular direction. For example, if cooling device  200  is mounted from a ceiling, fan  202  may push air downwards and across the area below the ceiling. Alternatively, for example, if cooling device  200  is mounted on a side wall (e.g., a vertical wall of a building), fan  2002  may push air across a particular area. In embodiments, fan  202  may push air (as shown as “incoming air” in  FIG. 2 ) that has initially passed through pads, such as pads  302 . In embodiments, fan  202  may be a variable speed driven fan or may be a constant speed driven fan. In embodiments, the blades of fan  202  may be manufactured from a metal material, a plastic material, or a hybrid material. In embodiments, fan  202  may have a motor size and blade dimensions that allow for minimizing noise, power requirements, vibration effects, and sizing of cover  204 , trough  206 , and pads  302  (as described in further drawings). 
     Cover  204  may be a cover that prevents air from being drawn in by the fan from across the surface upon which cover  204  is placed upon. In embodiments, cover  204  may be made from a metal material (e.g., aluminum, steel, copper, bronze, etc.), a plastic material, or a hybrid material. In embodiments, cover  204  may be non-transparent (as shown in  FIG. 2 ) or may be transparent (as shown in  FIG. 3 ). In embodiments, cover  204  may be octagonal, circular, rectangular, square, hexagonal, and/or any other shape. In embodiments, as shown in  FIG. 2 , an octagonal shape may allow for rectangular cuboid shaped pads  204  to be used. In alternate embodiments, a circular shaped cover  204  may allow for curved-shaped pads. In further alternate embodiments, cover  204  may include openings, passageways, slots of any shape, etc., that allow for air to enter from cover  204  and into circulation by fan  202  inside cooling device  200 . 
     Trough  206  may be structure that may store liquid and may also provide for ducting of air exiting cooling device  200 . In embodiments, trough  206  may be made from a metal material (e.g., aluminum, steel, galvanized steel, copper, bronze, etc.), a plastic material, or a hybrid material. In embodiments, trough  206  may be created by connecting multiple trough-shaped components (as further described in  FIGS. 15 and 16 ). In alternate embodiments, trough  206  may be manufactured as one continuous structure. In embodiments, trough  206  may hold any liquid that may drip/move from pad  302  that has not evaporated. In embodiments, trough  206  may be used as a duct for incoming air to be forced through cooling device  200 . In further embodiments, the shape of trough  206  (as further described in  FIGS. 15 and 16 ) allows for the dimension “S,” as shown in  FIG. 2 , of cooling device  200  to be reduced and, thus, reducing the amount of space taken up by cooling device  200 . While cover  204  and trough  206  may be separate manufactured components that connect together (as described in further figures), in alternate embodiments, cover  204  and trough  206  may be a single manufactured component. Connector  208  may connect cover  204  to trough  206 . 
     In embodiments, connector  208  may be a t-slotted bar (e.g., 80/20 long or short) that fits into apertures (e.g., holes, openings, etc.) within cover  204  and trough  206 . In alternate embodiments, connector  208  may be a non-slotted bar. 
       FIG. 3  shows another example diagram of cooling device  200 . In  FIG. 3 , cover  204  may be manufactured from a transparent material and allows for the internal components that make up cooling device  200  to be visible from a particular perspective view. As shown in  FIG. 3 , cooling device  200  includes fan  202 , bracket  203 , piping  214 , cover  204 , and pad  302  which is further described in  FIG. 12 . In embodiments, piping  214  is also described in further figures. In embodiments, bracket  203  may be used to connect cover  204  to trough  206  by using connectors, such as connector  306  (shown in  FIG. 11 ). 
       FIG. 4  shows a view of cooling device  200  when being viewed from the side of cooling device  200  where cover  204  is located. From this view, the central hub of fan  202  is visible. In embodiments and from this view, connector  208  is also visible. 
       FIG. 5  shows another view of cooling device  200  when being viewed from the area to which fan  202  will be forcing conditioned air. From this view, the blades of fan  202  are visible and a portion of cover  204  is visible when viewing from the side that shows the blades of the fan  202  that can circulate in a space created by trough  206  within cooling device  200 .  FIG. 5  also shows connecting rods  207 . In embodiments, connecting rods  207  connect fan  202  to trough  206  to provide stability to fan  202  during rotation. In alternate embodiments, cooling device  200  may not have any connecting rods  207   
       FIG. 6  shows another view of cooling device  200  when being viewed from the sides of cooling device  200  from where air will enter cooling device  200 . In embodiments,  FIG. 6  shows fan  202 , cover  204 , trough  206 , connector  208 , pad cover  210 , and pad  302 . In embodiments, there may one or more pad covers  210  as there may be one or more pads  302 . In embodiments, pad cover  210  may be a sheet of material, connected to cover  204  (e.g., welded, via a hinge, bolted on, etc.), that may be used to keep pad  302  within trough  206 . In alternate embodiments, pad cover  210  may be used to conceal part or all of pad  302  from external view. Thus, for example, if cooling device  200  is attached from a ceiling and cover  204  is closest to the ceiling, pad cover  210  may conceal a portion of pad  302  that is furthest from the ground. In alternate embodiments, pad cover  210  may be attached to trough  206  instead of being connected to cover  204 . Thus, for example, if cooling device  200  is attached from a ceiling and cover  204  is closest to the ceiling, pad cover  210  may conceal the portion of pad  302  that is closest to the ground. In embodiments, pad cover  210  may be cover about 20 to 100% of the surface of a particular pad  302 . 
     In embodiments, the blades of fan  202  may extend below trough  206 . For example, if cooling device  200  is mounted from a ceiling, the blades of fan  202  will be closer to the floor than the lower portion of trough  206 . In alternate embodiments, the blades of fan  202  may be at the same level as the lower portion of trough  206 . For example, if cooling device  200  is mounted from a ceiling, the lower portion of trough  206  will be at the same level as the blades of fan  202 . In further embodiments, the blades of fan  202  may be less than the level of the lower portion of trough  206 . For example, if cooling device  200  is mounted from a ceiling, the lower portion of trough  206  will be closer to the floor than the blades of fan  202 . 
       FIG. 7  shows a view of cover  204  when being viewed from a particular view (e.g., a top view as if viewing from a room ceiling).  FIG. 8  shows another view of cover  204  when being viewed from another particular view (e.g., as if looking up towards a ceiling). In embodiments,  FIG. 8  shows pad covers  210 , pump cover  212 , and piping  214 . In embodiments, piping  214  provide liquid (e.g., water) to each pad  302  that is within cooling device  200 . In embodiments, piping  214  may be traverse along one or more of the sides of cover  204  and may be attached to cover  204  via one or more connection devices. In embodiments, piping  214  may have a portion that is connected to a liquid supply device (e.g., a pump) that may be a part of cooling device  200  or may be a separate device from cooling device  200 . In embodiments, piping  214  may release liquid as a spray, jet, or sprinkle, from one or more openings, across the surface of piping  214 , over one or more surfaces of pad  302 . In embodiments, liquid openings on the surface of piping  214  may have nozzles or another device that can adjust the amount of liquid being transferred to each pad  302 . In embodiments, piping  214  may be tubes that are connected with each other (e.g., using elbow connectors). In alternate embodiments, piping  214  may be manufactured as a single device without the need for connectors. In alternate embodiments, piping  214  may be attached to sections of trough  206  that are closest to cover  204 . In further alternate embodiments, pad cover  210  and pump cover  212  may be attached to trough  206  instead of being connected to cover  204 . In embodiments, piping  214  may be connected to a pump system. In embodiments, the pump system may be controlled by a computing device, as described in  FIG. 24 . In embodiments, the pump system may be a dry pump system. In embodiments, some of the liquid that is supplied to pads  302  may be transfer to trough  206 . In embodiments, trough  206  may include a float valve, or other device, that detects the amount of liquid in trough  206 . In embodiments, if the amount of liquid in trough  206  exceeds a certain threshold (e.g., by weight, by water level, by cubic feet, etc.), the pump may operate and provide liquid supply, via piping  214 , to pads  302 . In embodiments, the threshold may be determined by a measuring instrument attached to trough  206  and controlled by a computing device as described in  FIG. 25 . In embodiments, some of the liquid in trough  206  may be pumped out of trough  206  and redistributed back to pads  302 . In embodiments, when the amount of liquid does not exceed a threshold, the pump may not operate and, accordingly, may not provide liquid to pads  302  via piping  214 . 
       FIG. 9  shows another view of cover  204  (e.g., a side view). In embodiments,  FIG. 9  shows cover  204  with connector  208 , pad covers  210 , pump cover  212 , and piping  214 .  FIG. 10  also shows another view of cover  204 . In embodiments,  FIG. 10  shows cover  204  with connector  208 , pad covers  210 , pump cover  212 , and piping  214 . As shown in  FIGS. 9 and 10 , pad covers  210  have a smaller height than pump cover  212 . In alternate embodiments, pad cover  210  may be the same height as pump cover  212  or may be of greater height than pump cover  212 . 
       FIG. 11  shows a perspective view of cooling device  200  without cover  204 . In embodiments,  FIG. 11  shows fan  202 , trough  206 , connector  208 , pad  302 , corner  304 , connector  306 , connector  308 , and pump connector  310 .  FIG. 12  shows the same perspective view of cooling device  200  as  FIG. 11 ; however,  FIG. 12  further shows connector  312 , and washer plate  314 . 
     In embodiments, pad  302  may be made from a cellulose material, fiberglass, or grass material, that allows for receiving liquid (e.g., water). In embodiments, pad  302  may be made from a rigid material or a flexible material. In embodiments, pad  302  may sit in trough  206  without any connecting device being inserted into pad  302 . In embodiments, pad  302  may be a shape with all linear sides, with some linear sides and some curved sides, and/or with all curved sides. In embodiments, fan  202  forces air through each pad  302 . As such, evaporation of the liquid in each pad  302  occurs based on the forced air from fan  202 . Accordingly, the evaporation of the liquid results in air that has passed over and through the pads to be cooler than when they entered cooling device  200 . In embodiments, liquid, such as water, may evaporate from each pad  302  at a particular range. As such, the evaporation of liquid from each pad  302  prevents any issues with mist. Furthermore, the change in temperature of air moved over pad  302  is less than when the air temperature prior to moving over pad  302  based on the evaporation of liquid from pad  302 . Thus, for example, if air enters pad  302  at 85 degrees Fahrenheit, the air may exit pad  302  at 77 to 78 degrees Fahrenheit. 
     In embodiments, corner  304  may be used to create an area within trough  206  to place a pad  302 . In embodiments, corner  304  may be attached to trough  206  with connectors, as further described in other figures. 
     In embodiments, connector  306  may be used to connect trough  206  with cover  204 . In embodiments, connector  308  may also be used to connect trough  206  with cover  204 . In embodiments, connectors  306  and  308  may both be types of a t-slotted bar (80/20). 
     In embodiments, pump connector  310  may be used to connect water piping with a pump. While not shown in the figures, a pump may be a part of cooling device  200  and may be located totally or partially within trough  206 . Alternatively, the pump may be a separate device that is not located within cooling device  200  and may operate based on receiving measurement information from one or more measuring devices located within trough  206 . 
     In embodiments, connector  312  may be used to maintain pad  302 &#39;s position within trough  206 . In embodiments, connector  312  may be made of metal, plastic, or a hybrid material. 
     In embodiments, washer plates  314  may be used to connect corner  304  to trough  206  and also may be used to connect connectors  306  and  308  to trough  206 . 
       FIG. 13  shows a perspective view of how connectors  306 , connectors  308 , and connectors  312  are located around trough  206 .  FIG. 14  shows another view of how connectors  306  and connectors  312  are located around trough  206  and their relationship to each other. In embodiments, the distance between connectors  312  provide a length sufficient to fit pad  302  so that  302  will not fall out of trough  206 . For example, if the length of pad  302  is 14 inches, the connectors  312  may be located about 14 to 14.1 inches. In embodiments, connectors  306  and  308  are located throughout trough  206   
       FIG. 15  shows another example of trough  206 . As shown in  FIG. 15 , this example of trough  206  shows trough  206  as being made up of multiple parts, such as part  206 A and  206 B. In embodiments, each part, such as part  206 A and  206 B may be connected to each other (e.g., by welding, soldering, gluing, etc.) to create trough  206 . In embodiments, trough  206  may include illuminating devices (e.g., lights, reflectors, etc.) that may be located on the portion of trough  206  that is furthest from cover  204 . Thus, if cooling device  200  is used when there is little or no sunlight present, cooling device  200  can also provide illumination in an area, such as an outside patio area. 
       FIG. 16  shows a view of a part of trough  206 , such as part  206 A. In embodiments, part  206 A has portions  206 AA,  206 AB, and  206 AC. In embodiments, portion  206 AA and  206 AC connect to portion  206 AB, each at an angle, such that the length “N” is less than length “M.” In embodiments, “N” may range from about 3 to 4 inches and “M” may range from 4.5 to 5.5 inches. However, in alternate embodiments, different dimension values may exist outside of these ranges. In embodiments, each part of trough  206 , such as part  206 A, may hold a pad  302 . In embodiments, portion  206 AA may be viewed as the exterior of part  206 A from outside cooling device  200  and, as such, the exterior of trough  206 . 
       FIG. 17  shows an example view of piping  214 . As shown in  FIG. 17 , piping  214  includes elbow  214 A, pipes  214 B, supply pipe  214 C, adaptor  214 D, and fitting  214 E. In embodiments, pipes  214 B are connected to each other with elbows  214 A. In embodiments, supply pipe  214 C is connected to pipes  214 B via elbows  214 A. 
       FIG. 18  shows an example pipe  214 B. In embodiments, pipe  214 B may be made of polyvinyl chloride (PVC), rubber, another type of plastic material, a metal material, or a hybrid material. In embodiments, pipe  214 B may have entry-ways (e.g., holes) that allow a liquid (e.g., water) to be exerted over each pad  302  located within cooling device  200 . In embodiments, the liquid may be pressurized from an external source that pumps water into pipe  214 B. In embodiments, each entry-way may be equally spaced or may not be equally spaced. 
       FIG. 19  shows different views of pad  302 . As shown in  FIG. 19 , pad  302  may have sides  302 A and  302 B. In embodiments, side  302 A has a dimension measurement “Z.” In embodiments, “Z” may range from about 10 inches to 16 inches. In embodiments, side  302 B has dimension measurements of “X” and “W.” In embodiments, “X” and “W” may range from about 4 inches to 8 inches. In alternate embodiments, the dimensions may be different and outside the above noted ranges. 
       FIG. 20  shows an exploded view of corner  304 . In embodiments,  FIG. 20  shows center  304 A, plates  304 B, and connectors  304 C. In embodiments, center  304 A may have a shape of a trapezoidal prism. In embodiments, corner  304  may be made of wood, metal, plastic, or of a hybrid material. In embodiments, plates  304 B may be attached to sides of center  304 A by using connectors  304 C through apertures within plates  304 B and center  304 A. In embodiments, connectors  304 C may be pins, screws, bolts, welding, and/or any other type of device for connecting two components. 
       FIG. 21  shows another exploded view of corner  304 .  FIG. 21  shows center  304 A, plates  304 B, and connectors  304 C. 
       FIG. 22  shows a schematic drawing of a pad, such as pad  302 . As shown in  FIG. 22 , the pad has a pad thickness (P), a pad medium, an incoming air velocity (u in ), an outgoing air velocity (u out ), incoming air temperature (T in ), incoming air relative humidity (RH in ), outgoing air relative humidity (RH out ), incoming liquid flowrate (Q in ), outgoing liquid flowrate (Q out ), evaporation rate (m evap ), and saturation of water (saturation water ). 
     In embodiments, the pad may be used in cooling device  200  and the particular components of cooling device  200  as described in  FIGS. 1B and 2-21 . In embodiments, the pad may utilize a cellulose material. In embodiments, the pad medium and the pad thickness (P) may have particular dimensions that allow for the pad to provide for (1) a temperature decrease in air, such that T out  is less than T in , (2) an increase in relative humidity, such that RH out  is greater than RH in , (3) a particular level of water saturation in the pad so that the pad does not dry out and also does not cause liquid mist to exit the pad, (4) an evaporation rate (m evap ) that ensures that T out  is less than T in  while maintaining a level of water saturation that prevents the pad from drying out, (5) an incoming liquid flowrate (Q in ) that ensures that the pad is saturated with a level of liquid, such as water, while providing for a particular evaporation rate (m evap ) and an outgoing liquid flowrate (Q out ) which ensures that T out  is less than T in  without resulting in (i) the pad from drying out, and/or (ii) mist from exiting the pad, and/or (6) a relationship between the change in temperature, from T out  and T in , and the amount of liquid saturation (e.g., saturation water ). 
     In embodiments, the thickness (P) of the pad may determine the size of cover  204  and trough  206 , as described in previous drawings. In embodiments, the thickness (P) of the pad may determine the quantity liquid provided by piping, such as piping  214  as described in previous drawings. In embodiments, the amount of liquid that flows from piping  214  may determine the incoming liquid flowrate (Q in ). In embodiments, the outgoing air velocity (u out ) may be the same or similar to the incoming air flow (u in ). In embodiments, the outgoing air velocity (u out ) may be air, once passed across the pad, which circulates within trough  206  and then being pushed down by fan  202  as described in the previous figures. In embodiments, the incoming air velocity (u in ) may determine that evaporation of liquid occurs without “over carry.” “Over carry” occurs when a liquid leaves the pad, and is pushed by fan  202 , before there is evaporation of the liquid and which results in mist. In embodiments, liquid that does not evaporate will be outgoing liquid flowrate (Q out ) which will flow into trough  206 . 
       FIG. 23  is a schematic drawing of cooling device  200  and fan  202 . In embodiments,  FIG. 23  describes the incoming airflow velocity (u 2in ), which is the air velocity that is exiting from a pad, such as the pad described in  FIG. 22 , and outgoing airflow (u 2out ) which is airflow velocity that is blown by fan  202  into an area. In embodiments, fan  202  may rotate at a given rotations per minute (RPM), input fan power (E in ), and at a given fan pitch to provide the desired outgoing airflow from fan  202 . In embodiments, the shape of cover  204  and trough  206 , described in earlier figures, may affect the incoming airflow velocity into fan  202  and the outgoing airflow velocity exiting from fan  202 . 
     In embodiments, each incoming airflow associated with each incoming airflow velocity combines together (U TOTAL ) near or above fan  202 , within the space created by combining cover  204  and trough  206 , before then exiting fan  202  as an outgoing airflow (u 2out ) associated with outgoing airflow velocity. In embodiments, the fan motor may be controlled by a computing device, as described in  FIG. 25 . 
     While the previous figures show pads  302 , alternate embodiments of cooling device  200  may not include any pads. Instead, cooling device  200  may use an atomization process to distribute liquid within and around fan  202  within  FIG. 2 . In embodiments, atomization may be considered as a process of converting a liquid into very fine particles or droplets. Accordingly, in alternate embodiments, cooling device  200  may not include corners  304 . Instead, cooling device  200  may have piping  214  to include particularly sized nozzles that receive liquid (e.g. via a pump or other device) that, when exerted through openings in piping  214 , result in the liquid being atomized. In embodiments, this results in atomized liquid being sprayed across fan  202 . As a result, trough  206  may not hold any water as the liquid is atomized and transferred away from cooling device  200  by fan  202 . 
     Also while the previous figures and embodiments show fan  202  operating at the same time as a pump is providing liquid to pads  302 , embodiments may have fan  202  operating only and no pump providing liquid to pads  302 . In embodiments, an electronic switch (e.g., on cooling device  200 , on a remote wireless controller to cooling device  200 , etc.) may switch the operation of cooling device  200  so that it is only uses fan  202  and the pump is not operating to provide liquid to pads  302 . In alternate embodiments, another electronic switch may open and close cover  204 . Thus, for example, if only fan  202  is operating, and not the pump, cover  204  may be opened for additional air supply. 
       FIGS. 24A and 24B  are diagrams of an alternate embodiment of cooling device  200 , cooling device  2400 . As shown in  FIGS. 24A and 24B , cooling device  2400  may a ceiling rod  2402 , shield  2404 , pad  2406 , float valve  2408 , and diffuser  2410 . In embodiments, ceiling rod  2402  may allow for cooling device  2400  to be connected to a ceiling directly or indirectly. In embodiments, shield  2404  may cover pad  2406  in a manner similar to pad cover  210  as described in previous figures. 
     In embodiments, pad  2406  may provide liquid to airflow in a manner similar to pad  302  as described in previous figures. In embodiments, float valve  2408  may be located in a trough-like structure, such as trough  206 , as described in previous figures. In embodiments, diffuser  2410  may connect to the bottom of cooling device  2400  and provide a particular type of airflow distribution from cooling device  2400  to the area surrounding cooling device  2400 . 
       FIG. 25  is a diagram of example components of a cooling device  200 . Device  2500  may correspond to computing devices that are part of cooling device  200  and/or a control system associated with cooling device  200 . Alternatively, or additionally, fan  202  and/or the pump may include one or more devices  2500  and/or one or more components of device  2500 . 
     As shown in  FIG. 25 , device  2500  may include a bus  2510 , a processor  2520 , a memory  2530 , an input component  2540 , an output component  2550 , and a communications interface  2560 . In other implementations, device  2500  may contain fewer components, additional components, different components, or differently arranged components than depicted in  FIG. 24 . Additionally, or alternatively, one or more components of device  2500  may perform one or more tasks described as being performed by one or more other components of device  2500 . 
     Bus  2510  may include a path that permits communications among the components of device  2500 . Processor  2520  may include one or more processors, microprocessors, or processing logic (e.g., a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC)) that interprets and executes instructions. Memory  2530  may include any type of dynamic storage device that stores information and instructions, for execution by processor  2520 , and/or any type of non-volatile storage device that stores information for use by processor  2520 . 
     Input component  2540  may include a mechanism that permits a user to input information to device  2500 , such as a keyboard, a keypad, a button, a switch, etc. Output component  2550  may include a mechanism that outputs information to the user, such as a display, a speaker, one or more light emitting diodes (LEDs), etc. 
     Communications interface  2560  may include any transceiver-like mechanism that enables device  2500  to communicate with other devices and/or systems. For example, communications interface  2560  may include an Ethernet interface, an optical interface, a coaxial interface, a wireless interface, or the like. 
     In another implementation, communications interface  2560  may include, for example, a transmitter that may convert baseband signals from processor  2520  to radio frequency (RF) signals and/or a receiver that may convert RF signals to baseband signals. Alternatively, communications interface  2560  may include a transceiver to perform functions of both a transmitter and a receiver of wireless communications (e.g., radio frequency, infrared, visual optics, etc.), wired communications (e.g., conductive wire, twisted pair cable, coaxial cable, transmission line, fiber optic cable, waveguide, etc.), or a combination of wireless and wired communications. 
     Communications interface  2560  may connect to an antenna assembly (not shown in  FIG. 3 ) for transmission and/or reception of the RF signals. The antenna assembly may include one or more antennas to transmit and/or receive RF signals over the air. The antenna assembly may, for example, receive RF signals from communications interface  2560  and transmit the RF signals over the air, and receive RF signals over the air and provide the RF signals to communications interface  2560 . In one implementation, for example, communications interface  2560  may communicate with a network (e.g., wireless network, Internet, Intranet, etc.). 
     As will be described in detail below, device  2500  may perform certain operations. Device  2500  may perform these operations in response to processor  2520  executing software instructions (e.g., computer program(s)) contained in a computer-readable medium, such as memory  2530 , a secondary storage device (e.g., hard disk, CD-ROM, etc.), or other forms of RAM or ROM. A computer-readable medium may be defined as a non-transitory memory device. A memory device may include space within a single physical memory device or spread across multiple physical memory devices. The software instructions may be read into memory  2530  from another computer-readable medium or from another device. The software instructions contained in memory  2530  may cause processor  2520  to perform processes described herein. Alternatively, hardwired circuitry may be used in place of or in combination with software instructions to implement processes described herein. Thus, implementations described herein are not limited to any specific combination of hardware circuitry and software.
