The air cooling apparatus 100 comprises an air circulation unit 101, a liquid reservoir 103 having a pump unit 104, and an ultrasonic liquid atomization system 102. The ultrasonic liquid atomization system 102 is being positioned below the air circulation unit 101 and above the liquid reservoir 103. The ultrasonic liquid atomization system 102 and the liquid reservoir 103 is positioned along the height of adjustable height pipe of the pedestal fan or table fan.
[0038] The ultrasonic liquid atomization system 102 comprises a mist generating chamber 102a 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. Here the liquid is water, however, any other liquid can be used which can generate mist particles. The plurality of piezo electric ultrasonic atomizers 106 are positioned on bottom surface of the mist generating chamber 102a. The mist generating chamber 102a is coupled with the pump unit 104 of the liquid reservoir 103 to receive the liquid via a connecting pipe 105. A drain valve 109 provided in the mist generating chamber 102a to maintain level of the liquid in the mist generating chamber 102a over the plurality of piezo electric ultrasonic atomizers 106. When there is access of liquid in the mist generating chamber 102a, the drain valve 109 drain out the excess liquid from the mist generating chamber 102a for effective mist generation by the plurality of piezo electric ultrasonic atomizers 106. The drain valve 109 drain out the excess liquid into the liquid reservoir 103 by means of a drain pipe.
[0039] The plurality of piezo electric ultrasonic atomizers 106 generates mist effectively when there is liquid upto some level on the surface of the plurality of piezo electric ultrasonic atomizers 106. Further, a gap is provided in between the mist generating surface and the outlet of the generated mist from the mist generating chamber 102a so that heavy particles settle down with effect of gravity and only fine liquid particles having size less than 8 microns further travel through to a mist transportation pipe 108 to a mist outlet unit 107.
[0040] The mist outlet unit 107 is being positioned in front of the air circulation unit 101 to release the mist of the fine liquid particles. The mist of the fine liquid particles is sprayed out by means of air pressure from the air circulation unit 101 and mix unanimously with blow air 111. The mist outlet unit 107 is coupled with upper portion of the mist generation chamber 102a with the mist transportation pipe 108. As shown in fig. 2, the mist outlet unit 107 has a plurality of holes 110, where each hole from the plurality of holes 110 is angularly positioned at an equidistant from each other. The mist outlet unit 107 is defined in a circular shape to distribute the generated mist in all direction along with the flow of blown air by the air circulation unit 101. The air circulation unit 101 comprises a blade unit and a motor coupled with the blade unit by means of a shaft to blow air. The motor may be an induction motor or Brush Less Direct Current (BLDC) motor. The air circulation unit 101 is positioned on the adjustable height pipe along which the ultrasonic liquid atomization system 102 and the liquid reservoir 103 is being mounted or positioned. Further, the ultrasonic liquid atomization system 102 and the liquid reservoir 103 are mounted in such a way that it enhances the aesthetic appeal.
[0041] In an embodiment, the mist generating chamber 102a is in a cylindrical structure shape extended in heightwise direction along the height adjustable pipe of the air circulation unit 101.
[0042] In another embodiment, the mist generating chamber 102a may be in box shape having a predefined height.
[0043] To achieve the effective cooling by mixing the generated mist with blow air, the mist generating chamber 102a is preferably positioned in proximity of the air circulation unit 101 to avoid losses due to gravity.
[0044] In an embodiment, the liquid reservoir 103 is a portable reservoir. The pump unit 105 is a submersible pump.
[0045] In an embodiment, the ultrasonic liquid atomization system 102 and the liquid reservoir 103 can be provided as a single unit 200 which is being disposed along the height of the pipe. Further, the pipe can be extended in height/length or fixed.
[0046] In an embodiment, number of piezo electric ultrasonic atomizers 106 depends on the capacity of air circulation unit 101 and area to be covered for cooling effect.
