[0001] The present disclosure relates generally to a field of cooling device for agricultural vehicle. More specifically, it pertains to a simple and effective cooling device which provides high fluid flow rate, high fluid static pressure, and low sound level.

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] For cooling various components of an agricultural vehicle, such as tractor, liquid flow among components is required. A water pump is coupled with various components and radiator enables liquid to extract heat from components. A hot liquid flows into a radiator for lowering down temperature, such that low temperature liquid again flows into various components for extracting heat, thus continuing liquid flow cycle in agricultural vehicle.
[0004] A fan configured with a radiator distributes forced fluid on radiator for lowering down temperature of liquid flow in an optimum time period. A belt pulley arrangement is mutually coupled with a fan and a water pump, such that a fan and a water pump is operated using belt pulley arrangement. Liquid inlet and liquid outlet of water pump is coupled with a radiator, and the fan is coupled between water pump and radiator such that fan enables forced cooling of liquid flowing inside a radiator of an agricultural vehicle.
[0005] A fan used in an agricultural vehicle generally includes more than six vanes. Vanes of fan rotates at very high speed, revolutions per minute (RPM), which increases eddy formation, thus contributing to increase sound level of a fan. Moreover, an increase in sound level of fan contributes to overall sound level of an agricultural vehicle. The sound level of an agricultural vehicle thus increases above a threshold limit of sound level as prescribed by the Bi standard limit sound (BSL), which enables failure of an agricultural vehicle in test of BSL.
[0006] As water pump and fan are mutually coupled with a belt pulley arrangement, such that reducing RPM of fan, simultaneously, lowers operation of water pump, which enables decreasing fluid flow in various components of an agricultural vehicle thus leading to failure of an agricultural vehicle.
[0007] In an existing technology, an axially designed vanes of fan having similar angle of approach and angle of discharge generates less volume of fluid flow rate and less fluid static pressure. Thus, fan is unable to provide optimum cooling of liquid inside a radiator within a time frame which decreases overall efficiency of a radiator, and increase in consumption of an engine power. Moreover, decrease in performance of a radiator leads to deterioration of various components, such as engine components, of an agricultural vehicle.
[0008] There is, therefore, a need in the art to provide a simple, compact, and cost effective cooling device for an agricultural vehicle which provides high static pressure, high fluid flow rate, and low sound level.

OBJECTS OF THE INVENTION
[0009] A general object of the present disclosure is to provide an efficient and economical solution for providing high fluid flow rate, high static pressure, and low sound.

[0011] Another object of the present disclosure is to provide a cooling device for agriculture vehicle which provides effective cooling at low RPM.

In preferred embodiment, the profile of the plurality of vanes surface 110 extending from the vane tip 106 to the vane root 108 can be configured as convex-concave shape.
[0057] In an embodiment, the vane root 108 of the plurality of vanes 104 can be coupled with the hub 102, such that the rotation of the hub 102 enables rotation the plurality of vanes 104 in same direction. The vane root 108 can be coupled with hub 102 such that the plurality of vanes 104 can be extended in radial direction outward from the hub 102. In an exemplary embodiment, the hub rotating in a clockwise direction enables the plurality of vanes to rotate in a clockwise direction.

Moreover, the cooling device 100 at 3000 RPM can generate 1.8085 kg/s, which represents a substantial increase in efficiency of the cooling device 100 when compared to the prior arts.

[0064] FIG. 2 illustrates a cross-sectional representation for implementation of the cooling device 100 in an agricultural vehicle, in accordance with an embodiment of the present disclosure.
[0065] In an exemplary embodiment, an agricultural vehicle can include a water pump unit 202, a belt pulley arrangement, a cooling device 100, a radiator 204, and the like. The belt pulley arrangement can be coupled with the water pump 202, and the belt pulley arrangement can be coupled with the cooling device 100, such that the belt pulley arrangement enables operation of the water pump 202 and the cooling device 100. The radiator 204 can be configured on front of the cooling device 100, and the cooling device 100 can be configured between the water pump 202 and the radiator 204. The cooling device 100 receives the fluid from rear of the plurality of vanes 100 and with high fluid flow rate distributes the fluid at the radiator 204, such that the fluid flow of the cooling device 100 enables cooling of a liquid flow inside the radiator 204. As the belt pulley arrangement can be mutually coupled with the water pump 202 and the cooling device 100, so the cooling device 100 can be designed such that the cooling device 100 with predefined RPM can distribute more fluid with large fluid flow rate and high static pressure with low sound on the radiator 204, thus decreasing temperature of the liquid flow inside the radiator 204.
[0066] FIG. 3 illustrates an exemplary sound level analysis of the cooling device 100 in an agricultural vehicle, in accordance with an embodiment of the present disclosure.
[0067] In an exemplary embodiment, the graph shows a comparison analysis of sound level between the cooling device 100, existing device (prior art), and an engine unit without existing device. The graph represents the sound level which can be measured in decibel db(A), and frequency can be measured in Hertz (Hz). A sound hearing capacity of human can be sensitive between 500 to 2000 Hz. The existing device operating at 2700 rpm can produce maximum sound level of 105 db(A), and the cooling device 100 operating at 2700 rpm can produce maximum sound level of 93 db(A). In another embodiment, the sound level difference between the existing device (prior art) and the cooling device 100 can be 12 db(A), which can be a substantially low sound level for the cooling device 100 for passing stipulated sound norms of bi - standard level sound (BSL). In yet another exemplary embodiment, an average sound level difference of cooling device 100 and existing device (prior art) operating between frequency range of 50 to 6300 Hz can be substantially decreased to 4 db(A).
[0068] In an exemplary embodiment, the engine unit without installing an existing device (prior art) can generate low sound level compared to the existing device (prior art), which can represent that the existing device (prior art) contributes in increasing sound level of the engine unit of the agricultural vehicle.
