[0001] Preamble to the Description
[0002] The following specification particularly describes the invention and the manner in which it is to be performed:
[0003] Description of the invention:
[0004] Technical field of the invention
[0005] The present invention relates to an apparatus to integrate the water pump and fan with the motor. More particularly, the present invention uses a single electric motor to drive both the water pump and the fan in cooler applications.
[0006] Background of the invention
[0007] Generally, evaporative cooling improves workplace productivity by keeping workers cool in the workplace which, in turn, reduces heat-related illness, particularly in the summer months and/or in hotter climates. It also improves performance of sports players by keeping players cool or preventing heat exhaustion in sports that demand extended periods of physical exertion.
[0008] In cooler applications, the water pumps and fans are provided in association with the cooling system of the motor. Generally, electric motors are used for driving the water pump and fan in the cooler applications. The cooling fan device is driven for drawing and blowing the air across the air or desert cooler. The water pump is driven to generate and circulate the flow of water through the cooler. In air or desert cooler, the air flowing through the cooler cools the water as it flows therein. Ideally, the relationship of the water flow and air flow through the cooler should be such as to provide the optimum desired cooling throughout. The air and water flow is dependent upon the speed of operation of the fan device and water pump.
[0009] Various types conventional coolers are in the prior arts. The United States Patent document 3272188 A describes a combination fan and water pump drive.

In the cited document, the fan device is associated with an internal combustion engine from the engine through a viscous fluid coupling, and the water pump impeller is commonly driven directly from the engine. A viscous fluid coupling is desirable for driving the fan device, as is well known, because its output speed falls off at high input speeds. Since the water pump impeller is driven directly from the engine, at high engine speeds, the speed of the pump impeller is substantially greater than the speed of the fan device.
[0010] The United States Patent document 2678031 A describes a radiator fan and coolant impeller speed control mechanism. In the cited document, the mechanism comprises a fan element, a casing having an intake and outlet connected in a coolant liquid circulating system, a pump or impeller element in the casing, an engine actuated drive wheel rotatable relatively to both elements, and a releasable friction clutch means including friction clutch shoes carried by and rotatable with at least one of said elements, and a clutch surface on the drive wheel with which the shoes frictionally engage, the clutch shoes being spring pressed and movable centrifugally outward to reduce the friction pressure on the friction surface, or surfaces, of the wheel as the speed of the elements carrying the friction shoes increases above a predetermined R. P. M., whereby both the speed of the fan element and the speed of the impeller element remain at predetermined maximums at all engine R. P. M. above a predetermined R. P. M. of the engine.
[0011] Typical, the claimed conventional coolers use two different motors for controlling the water pump and fan i.e. one motor is used to control the water pump and other motor is used to control the fan. Typically, in conventional coolers, both water pump and the fan are not integrated with the motor in the motor casing i.e. the water pump, the fan and the motor are not integrated and housed in the single motor casing. Conventional coolers require two different controllers to control speed of the water pump and the fan. Conventional air cooler uses a submersible water pumps and gets fail when water pump runs at empty conditions. Typically, the conventional coolers do not use the single

rotating shaft which is extended on either side of the motor to mount the water pump and the fan on either side of it.
[0012] Hence, there is a need for an apparatus to integrate the water pump and fan with the motor. More particularly, the present invention uses a single electric motor to drive both the water pump and the fan in cooler applications.

[0017] In preferred embodiment of the invention, the rotating shaft is further extended on either side of the motor, wherein one side of the rotating shaft is mounted with the water pump and other side of the rotating shaft is mounted with the fan.
[0018] In preferred embodiment of the invention, the motor controls the water flow and air flow at the rated speed by driving both the water pump and the fan simultaneously.
