FIELD OF THE INVENTION:
[001] The present invention relates to a radiator of a vehicle and a cooling system of a vehicle incorporating the same.

BACKGROUND OF THE INVENTION:
[002] Vehicle such as a two-wheeled vehicle comprises a radiator for dissipating heat produced during operation of the vehicle. The amount of heat generated by the vehicle depends on capacity of the vehicle, speed of the vehicle, load onthe vehicle and other parameters. In one example, a vehicle with higher capacity produces a larger amount of heat in comparison to a vehicle with lower capacity. Similarly, a vehicle running at higher speed produces a large amount of heat in comparison to the same vehicle running at lower speed. Since, the rate of heat dissipation by the radiator is proportional to its size, there is a requirement of a large size radiator in case of the vehicle generating large amount of heat.

[003] Although, large size of the radiator may enhances rate of dissipation of the heat from the vehicle. But, the larger size of the radiator also affects the performance of the vehicle by increasing a drag experienced by the vehicle while in motion. In addition to that, other problems related to an increased size of the radiator includes a decreasing in overall maneuverability of the motorcycle, especially in tight spaces or when making sharp turns, a compromise in the aesthetic appeal of the vehicle, and other problems known to a person skilled in the art.

[004] Thus, there is a requirement of providing a solution to one or more than one of the aforesaid problems.

Further, upon a value of the primary parameter, a value of the secondary parameters, and a value of both the primary parameter and the secondary parameter comes below the threshold limit, the electronic control unit (203) provides a signal to the auxiliary body (104) to come to the first state i.e. the retracted state with respect to the main body (102) leading to decrease in the heat transfer area of the radiator (100) to attain its original value.

[0052] Now referring to Figure 5, the main body (102) comprises a first port (108) and a second port (110). Further, the at least one auxiliary body (104) comprises a first auxiliary body (112) and a second auxiliary body (118).

[0056] Now coming to operation of the cooling medium communication circuit (206), in the first state of the at least one auxiliary body (104), the electronic control unit (203) allows flow of the cooling medium from the drive source (12) to the main body (102) via the first cooling medium communication path (208) and the flow of the cooling medium from the main body (102) to the drive source (12) via the fourth cooling medium communication path (216).

[0057] In a similar way, in the second state of the at least one auxiliary body (104), the electronic control unit (203) allows flow of the cooling medium from the drive source (12) to the radiator (100) via the first cooling medium communication path (208), the second cooling medium communication path (212) and the third cooling medium communication path (214), and the flow of the cooling medium from the radiator (100) to the drive source (12) via the fourth cooling medium communication path (216), the fifth cooling medium communication path (220) and the sixth cooling medium communication path (222).

[0058] Since, the auxiliary body (104) of the radiator can be temporally brought to the extended state with respect to the main body (102) upon requirement of a larger heat transfer area and can be brought back to the retracted state with respect to the main body (102) after there is no requirement of the larger heat transfer area. One of the advantages of the present invention includes, efficiently removing the heat produced by the vehicle during movement without compromising on vehicular performance, vehicular aesthetics and maneuverability of the vehicle (10).

[0059] Further, as the radiator is foldable in nature i.e. adaptable to attain the first state and the second state. Based on the vehicle running condition, the radiator can be brought to the first state i.e. retracted state, so, that air drag experienced by the vehicle gets reduced leading to an enhancement in efficiency of the engine.

[0060] Since, the movement of the auxiliary body allows easier access to other components of the motorcycle for routine checks or repairs. One advantage of the present invention includes an increase in serviceability simplify and a reduction in time and effort required forthe service of the vehicle.

[0061] Since, the rider can also adjust the radiator configuration as pre-emptive measurement based on factors such as temperature, speed, or the type of terrain. One of the advantages of the present invention includes an increase in adaptation of the vehicle.
