, Description:Field of invention

The present invention relates to an evaporative cooling system, and more particularly, the present invention relates to evaporative cooling system which provides cooling effect to operator on a tractor and/or off-road vehicle.

Background of the invention

In most commonly used evaporators, water storage with water circulation mechanism and cooling pads are used. For evaporation to take place, a water pump is used to deliver the water from a storage tank through vertical channel. Then horizontal channels with inbuilt holes are placed such that the water is sprinkled on the top of the cooling pads.

Further, to control and operate the abovementioned mechanisms, other supportive mechanisms are used such as the water float sensors to control the water level, switch to on-off the water pump and the like.

Specifically, the cooling pads are sandwiched between the door and support in order to keep the cooling pads fixed with door. Such doors with this arrangement of cooling pads are used on the cut of the enclosed body so that incoming fresh air should come in direct contact with the water soaked pads then sucked by the fan to deliver the cool, and humid air.

However, the prior art evaporative systems works only for summer season to give cooling effect. Separate heating system is required in winter season for to maintain temperature of surrounding at comfort level.

Specifically, US Patent No. 6895772B2 discloses an evaporative cooler that has multi sided cabinet with individual evaporative cooling pads .These cooling pads are sandwiched between the door and the wire mesh. However, this makes the replacement very difficult. Due to involvement of oscillating and rotatable spout on the top, makes the overall system very complex, heavy and not a standalone system.

Another US Patent No. 2,223,884 shows an evaporative cooling unit used on an automobile. However, there is no driven cooling fan of any kind because stream of the moving automobile creates the air flow through a wetted cooling pad. There is a movable air duct to direct cooled air to a predetermined location.

Yet another Japanese Patent Application JP2006310766A shows indirect type of evaporative cooling device. The device has corrugated boards joined through plastic films such that water supplied to boards is vaporized by supplying dry air through holes in boards. With this cooling pad the direction of air to enter in the pad is specified due to structure of pad restricts the placing of pad in the water sump.

As discussed above, the prior art systems are heavy and bulky hence it’s very difficult to shift them from place to another. Further, it requires desired space to keep the system to work, and modification is required in the required area as per the shape, size of the system.

Furthermore, cooling pad life is very less and has to be replaced very frequently. If not changed then problem of improper cooling starts. Also, due to bulky in size, the evaporative system of the prior art is heavy in weight and is not a standalone system. The prior art system can’t be used for multipurpose location based requirement.

Accordingly, there exists a need to provide an evaporative cooling system, which overcomes above-mentioned drawbacks.

Objects of the present invention

An object of the present is to provide a standalone evaporative cooling system which is portable.

Another object of the present invention is to provide an evaporative cooling system with replaceable cooling pads.

Another object of the present innovation is to provide as evaporative cooling system with heater option.

Summary of the invention

Accordingly, the present invention provides an evaporative cooling system. The evaporative cooling system comprises a weldment base and a top cover capable of being assembled over the weldment base. The evaporative cooling system further comprises a blower assembly configured within the weldment base, and a moist filter casing configured within the weldment base in front of the blower assembly. The moist filter casing includes a moist filter/cooling pads, and a water distributor configured above the moist filter. The water distributor includes water channels/tubes with holes through which water is sprayed on the moist filter making the moist filter soaked with water, and a cover for covering the moist filter and the water distributor. The evaporative cooling system further comprises a grill assembly configured in front of the moist filter casing on a side of the top cover. The grill assembly includes filter papers for restricting entry of heavy particle along with air sucked by blower. The evaporative cooling system also comprises a water pump for supplying water to the water distributor. Wherein, air sucked by the blower comes in contact with water within the moist filter casing, the temperature of the air is dropped and the humid and cool air passed through an air duct.
