The following specification particularly describes the invention and the manner in which it is to be performed

BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to an air-cooling device, and more particularly to an air cooler especially a desert cooler.
Description of Related Art
[002] Air cooler is typically designed with water circulation through perforated pads around a body of the air cooler. Further, a fan is installed within the air cooler that is powered by an electric motor fixed in a center of the body of the air cooler. Air gets cooled by a process of evaporation of water droplets and delivers cool air to a surrounding environment through the fan connected to a motor shaft. However, depending on a capacity of the electric motor, heat is generated by the electric motor and dissipated to the air circulating around the electric motor. In such scenario, some amount of the heat is further added to the cool air, which causes reduction in cooling capacity of the air cooler. To overcome the aforementioned issue, various types of air coolers have been disclosed.
[003] In a conventional air cooler, the heat is removed from the electric motor by providing forced air cooling. This is commonly done by providing the fan to blow the air over the electric motor. However, such method of removing the heat from the air cooler is not efficient and consumes more electricity.
[004] Thus, there is a need for a technical solution that overcomes the aforementioned problems of the conventional air cooler.
SUMMARY
[005] Embodiments in accordance with the present invention provide an air cooler comprising: a motor. The motor comprises a first shaft and a second shaft. The air cooler further comprising: a first fan coupled to the first shaft of the motor. The first fan is adapted to blow cool air in an outward direction from the air cooler. The air cooler further comprising a second fan coupled to the second shaft of the motor. The second fan is adapted to blow air towards the motor. The air cooler further comprising a cooling duct substantially encloses the motor and the second fan. The cooling duct comprises a first end to exhaust hot air from the air cooler.
[006] Embodiments of the present invention may provide a number of advantages depending on its particular configuration. First, embodiments of the present application may provide an air cooler that may restrict heat generated by a motor of the air cooler from getting mixed with cool air blown in an outward direction from the air cooler.
[007] Next, embodiments of the present invention may provide an air cooler that may be provided with a cooling duct to make a provision for cooling a motor to avoid overheating of the motor during working, thus improving a cooling efficiency of the air cooler.
