BACKGROUND
[002] Background description includes information that may be useful in understanding the present subject matter.
[003] Existing table top coolers are working on the principle to generate vapours of water for generating cooling effect which requires cooling pad for evaporation of water and a water pump to supply water to all cooling pads. The evaporative coolers work efficiently during hot conditions and have bad impact on health during humidity conditions.
[004] Technical problem associated with existing table top generally referred as personal coolers which are small in size and require efficient cooling which is not possible in the existing table top evaporative coolers.
[005] Another technical problem associated with the existing table top evaporative cooler is size of water droplets which is large that create moisture in the environment and threat of corrosion to surrounding components prone to rust.
[006] Another technical problem associated with the existing table top evaporative cooler during humid days is that water droplets remain on the human body to increase discomfort and increase heat index. The impact of humidity is discomfort which can result in to fatigue, dehydration, muscle cramp, etc., to humans.
[007] Another technical problem associated with the existing table top evaporative cooler is wastage of water or liquid.
[008] With the big size of water vapours or water droplets in the existing fan unit and the evaporative cooler, the water vapours or water droplets gets settle down in short span of time which reduces the cooling effect.
[009] Accordingly, the existing table top evaporative coolers are not efficient in terms of cooling for long time and comfortable cooling to human beings.
[0010] There is need in the art to provide a table top evaporative cooler that can eliminate the above mentioned technical problems with less manufacturing and operational cost.

[0041] Referring to fig. 1, 2, and 3 the present subject matter illustrates air cooling apparatus in accordance with embodiments of the present subject matter. As shown in fig. 1, 2 and 3, the present air cooling apparatus 100 is a table top cooler. The air cooling apparatus 100 comprising a fan blower 101 which is a centrifugal fan or blower coupled with an air duct 102 (shown in fig. 3) to throw air in predefined direction and a liquid reservoir 104 having a pump unit. The liquid reservoir 104 is being positioned below the fan blower 101. The air cooling apparatus 100 further comprises an ultrasonic liquid atomization system which is being positioned below the fan blower 101 and below the air duct 102. The ultrasonic liquid atomization system generates mist of fine liquid particles. The ultrasonic liquid atomization system comprising a mist generating chamber 105 having a plurality of piezo electric ultrasonic atomizers 106 to pass ultrasonic wave through the liquid to facilitate generation of mist of fine liquid particles. The mist generating chamber 105 is coupled with the pump unit of the liquid reservoir 104 to receive the liquid via a connecting pipe 104a. The mist generating chamber 105 is positioned below the air duct 102 and coupled with a mist channel 106.
[0042] The mist channel 106 is connected with the mist generating chamber 105 at one end and with mist outlet channel 107 at other end. The mist outlet channel 107 having a mist outlet portion 107a at each side. The mist outlet channel 107 can be of any shape such as rectangular, square, circle, oval. The mist outlet channel 107 is positioned at outlet of the air duct 102 so that the mist coming out from the mist outlet portion 107a can mix with the air thrown by the fan blower 101 and coming out through the air duct 102. The mist from the mist outlet portions 107a released by pressure of the thrown air from the fan blower 101.
[0043] In an embodiment, a drain valve is provided in the mist generating chamber 105 to maintain level of the liquid in the mist generating chamber 105 over the plurality of piezo electric ultrasonic atomizers 106.
[0044] As shown in fig. 1 and 2, where the mist generating chamber 105 is connected with a mist channel to allow passage of generated mist. As shown in fig. 2 and 3, the air cooling apparatus 100 comprises the fan blower 101 that is coupled with an air duct housing 102 to throw air in predefined direction. The fan blower 101 is coupled with a motor to suck air from a plurality of holes (not shown in the figures) and direct the sucked air with pressure towards outlet 103 of the air duct housing 102. The fan blower 101 is positioned in the blower housing to throw air in centrifugal direction. Further, a liquid reservoir 104 having a pump unit and positioned below the fan blower 101.
[0045] As the mist generating chamber 105 is coupled with the pump unit of the liquid reservoir 104 to receive the liquid via an inlet connecting pipe 104a. The mist generating chamber 105 comprises a drain valve (not shown) which is positioned below inlet point of the inlet connecting pipe 104a to maintain level of the liquid in the mist generating chamber 105 over the plurality of piezo electric ultrasonic atomizers 106 to achieve effective generation of the mist. If the liquid level is high, the plurality of piezo electric ultrasonic atomizers 106 have high pressure due to more liquid. To achieve the effective generation of mist, a predefined level of liquid is maintained over the plurality of piezo electric ultrasonic atomizers 106.
[0046] As shown in Fig. 2, the mist generating chamber 105 of the air cooling apparatus 100 is provided with a blower or secondary blower 108. The blower 108 is positioned over the mist generating chamber 105 to create air pressure inside the mist generating chamber 105 so that generated mist can move in the mist channel 106 with pace and reaches each mist outlet portion 107a of the mist outlet channel 107.
[0047] As explained with reference to figure, the fan blower 201 is centrifugal fan. Further, the blower 108 can be a centrifugal fan or axial fan, preferably, centrifugal fan.
[0048] In an embodiment as shown in fig. 1, the blower may not be present as it is not the limiting feature of the present subject matter but can be seen as the optional feature as the mist generated can itself traverse towards the mist outlet channel by virtue of its low weight or obeying the law of equilibrium which states that to attain an equilibrium a gas moves from a high pressure side to the low pressure side. But with the help of the external blower 108 mist can be pressurized to move at a faster pace towards the mist outlet channel 107.
[0049] The blower 108 takes electric supply from the main electric unit 110 of the air cooling apparatus 100. The blower 108 takes less power as compared to the main fan blower 101 as shown in the figure.
[0050] As explained with reference to figures 1-3, the air cooling apparatus 100 is a table top cooler with water cooling pads.
[0051] As explained with reference to figures 1-3, the air cooling apparatus 100is a table top cooler without water cooling pads.
