DETAILED DESCRIPTION
[009] In conventional vehicles, a higher efficiency and a better performance is achieved by cooling all the vehicle components efficiently. Furthermore, a conventional vehicle incorporates expensive natural air cooling or liquid cooling mechanisms for an internal combustion engine in a vehicle.
[010] In order to combat with increasing global warming, the automobile manufacturers have started to manufacture electric vehicles and hybrid electric vehicles. In such electric and hybrid electric vehicles, a cooling system is installed focused on cooling a battery and a traction motor.
[011] Although one or more electric components in the electric and hybrid electric vehicle have higher efficiency, however these electric components generates a lot of heat due to regular working. Further, these higher temperatures of the electric components due to high heat further reduces the performance of the vehicle. Therefore, an efficient cooling system to cool the electric components and further increase the durability of the powertrain components is required.
[012] In order to prevent overheating of the electric components in vehicles, natural cooling through natural air is incorporated to dissipate heat away from the electrical components. The natural air cooling is comparatively cheaper, however naturally air cooling is slow and does not adequately dissipate heat from all the electrical components, rather it only dissipates heat away from a surface of the electrical component.
[013] In some vehicles, a forced air cooling through an inbuilt fan is also introduced for effective cooling of the vehicle. However, forced air cooling through the fan is not efficient with vehicles with higher performance due to rapidity required in cooling of the vehicle, which the fan is incapable to provide. Further, forced air cooling through a fan also generates noise which further interrupts with the vehicle operation.
[014] In some vehicles, liquid cooling is introduced to provide effective cooling of the vehicles. In some conventional designs, a three-way valve is introduced for heat exchange from an engine and other electrical components to two separate cooling circuits. The first cooling circuit uses a water pump to circulate water and cool the engine, and the second cooling circuit uses an oil pump to circulate oil to cool motor and other electrical components. This design effectively cools down the vehicle components, however it consumes a lot of space. Further, a separate water pump and an oil pump requires a separation requirement to prevent mixing of the oil and water with each which in turn will affect the functioning of the vehicle.
[015] In another related art, a valve is used to control flow of the coolant to an engine and the other electrical components based on temperature of the engine and other electrical components as well as the coolant. However, this method uses a single valve to provide supply of coolant to the vehicle components, which burdens the valve. Further, during any delay or fault if the valve is unable to operate or it remains closed, then no coolant will be circulated and the vehicle components will not be cooled.
[016] In another related art, two separate coolant pumps are used to cool an engine and other electrical components of the vehicle such as a motor, which further exchanges heats from respective cooling areas where the coolant reaches to note down a temperature difference between the engine and the motor and thereby cool the components according to the temperature difference.
[017] In another related art, a liquid cooling system includes a radiator, a chiller, a cooler, a heater and a plurality of coolant pump to cool the vehicle. Though this arrangement cools the vehicle, however it increases the part count, cost and space acquired by the cooling system in the vehicle. Hence, this arrangement incidentally also increases the cost of the vehicle.
[018] Hence, it is an object of the present invention to overcome all the above stated and other related problems existing in the prior arts, with respect to a liquid cooling system of a vehicle for rapid cooling of the vehicle components as well as other problems of known art.
[019] It is further an object of the present invention to provide a liquid cooling mechanism to cool one or more vehicle components.
[020] It is further an object of the present invention to provide a mechanism to cool the coolant for prevention of regular change of the coolant.
[021] It is further an object of the present invention to increase efficiency of the vehicle by rapid cooling of the vehicle components through a coolant.

[046] The cooling system (100) comprises of a coolant being stored inside a coolant tank (104). The coolant stored inside the coolant tank (104) is of a low temperature and therefore the coolant being a cold coolant. The coolant tank (104) is connected to a coolant pump (106).

In one embodiment, the plurality of vehicle components (110, 112, 114, 116, 118) also includes an internal combustion engine. The coolant pump (106) is further connected with a plurality of valves (120, 122, 124, 126, 128). The plurality of valves (120, 122, 124, 126, 128) are individually connected with one of the pluralities of vehicle components (110, 112, 114, 116, 118) and opens to supply the cold coolant to each of the plurality of vehicle components (110, 112, 114, 116, 118).

The one or more predetermined parameters are temperature of each of the plurality of vehicle components (110, 112, 114, 116, 118) determined by one or more temperature sensors installed on the vehicle (400), temperature of the cold coolant. Further, the coolant of higher temperature is passed a plurality of thin tubes and provided by natural air circulation when the vehicle (400) is running. This cools the coolant of higher temperature to an ambient temperature. In another embodiment, the fan (108) is connected to the radiator (102) for enabling forced cooling. The fan (108) forcibly cools the coolant of higher temperature when it crosses an average operating temperature.

Further, an inlet of the radiator (102) is connected with the each of said plurality of vehicle components (110, 112, 114, 116, 118). In one embodiment, the radiator (102) cooling surface is placed perpendicular to an air velocity for effective natural cooling of the vehicle (400) in the running condition of the vehicle (400).

The vehicle control unit (110) is electrically connected to the plurality of vehicle components (112, 114, 116, 118). The vehicle control unit (110) is connected electrically with the traction motor (112), the motor control unit (114), the battery (118), and the charger (116) in an input side and. Further, the vehicle control unit (110) is connected with the fan (108), the coolant pump (106), and the plurality of valves (120, 122, 124, 126, 128) in an output side. Further, the battery (118) of the traction motor (112) is electrically connected with both the fan (108) and the coolant pump (106).
[052] The vehicle control unit (110) controls an amount of power which is to be provided to the coolant pump (106) based on predefined factors. The predefined factors are total number of valves being open among the plurality of valves (120, 122, 124, 126, 128), a real-time temperature of each of the plurality of vehicle components (110, 112, 114, 116, 118) detected through the one or more temperature sensors, and an ambient temperature of the vehicle (400), for regulating flow of the coolant from the coolant pump (106) to at least one of the plurality of valves (120, 122, 124, 126, 128).

The vehicle control unit (110) starts the coolant pump (106) and opens a control valve of the plurality of valves (120, 122, 124, 126, 128) attached to the one of the plurality of vehicle components (110, 112, 114, 116, 118), for allowing the cold coolant to flow through at least one of the plurality of vehicle components (110, 112, 114, 116, 118) and keep other control valves of the plurality of valves (120, 122, 124, 126, 128) in close condition. This enables cooling of individual vehicle components without affecting the overall efficiency of the vehicle (400).
[054] In one embodiment, the battery (118) supplies current to the coolant fan (106) and the fan (108) and thereby eradicates requirement of an additional power source.

[055] Figure 3a illustrates a method (300) of cooling a plurality of vehicle components by the cooling system (100), in accordance with an embodiment of the present subject matter. Figure 3b illustrates the method (300) of cooling the plurality of vehicle components by the cooling system (100), in accordance with an embodiment of the present subject matter. For brevity figures 3a and 3b will be discussed together. A method (300) for cooling the plurality of vehicle components (110, 112, 114, 116, 118) through the cooling system (100) in the vehicle (400) comprising the following steps. The vehicle control unit (110) in step 302 determines a temperature of at least one of the pluralities of vehicle components (110,112,114,116,118). In step 304, the vehicle control unit (110) analyzes when the temperature of at least one of the pluralities of vehicle components (110,112,114,116,118) is greater than a critical temperature of at least one of the pluralities of vehicle components (110, 112, 114, 116,118). If the temperature of at least one of the pluralities of vehicle components (110,112,114,116,118) is greater than a critical temperature of at least one of the pluralities of vehicle components (110, 112, 114, 116,118), then the vehicle control unit (110) opens a control valve of the plurality of control valves (120, 122, 124, 126, 128) to allow the coolant to flow to at least one of the plurality of vehicle components (110, 112, 114, 116, 118) as shown in step 308. In step 310, the vehicle control unit (110) controls the coolant flow by controlling the coolant pump (106). In step 306, the vehicle control unit (110) keeps the control valve of the plurality of control valves (120, 122, 124, 126, 128) in closed condition when the temperature of at least one of the plurality of vehicle components (110, 112, 114, 116, 118) is not greater than the critical temperature of at least one of the plurality of vehicle components (110, 112, 114, 116, 118).
[056] Further, in step 312, the vehicle control unit (110) determines the temperature of the cold coolant, and in step 314, the vehicle control unit (110) determines the ambient temperature of the vehicle (400). Thereafter, the vehicle control unit (110) further determines the temperature of at least one of the components of the plurality of vehicle components (110, 112, 114, 116, 118) and thereafter controls the flow of the coolant by the coolant pump (106) as shown in step 310.

Further, in step 318, the vehicle control unit (110) analyzes if the temperature of the coolant of higher temperature is greater than a critical temperature of the coolant, and then switching on the fan (108) as shown in step 324. If the temperature of the coolant of higher temperature is not greater than the critical temperature of the coolant, then the vehicle control unit (110) switches off the fan (108).
[058] In step 312, once the vehicle control unit (110) determines the temperature of the coolant, the vehicle control unit (110) further monitors a temperature difference between the temperature of the coolant and the ambient temperature of the vehicle (400) as shown in step 316. Thereafter, the vehicle control unit (110) analyzes the temperature difference between the temperature of the coolant and the ambient temperature is greater than a critical temperature difference between the temperature of the coolant and the ambient temperature as shown in step 320, then the vehicle control unit (110) switches on the fan (108) as shown in step 324. If the temperature difference between the temperature of the coolant and the ambient temperature is not greater than the critical temperature difference between the temperature of the coolant and the ambient temperature, then the vehicle control unit (110) switches off the fan (108) as shown in step 322.
