COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it is to be performed.

BACKGROUND
Technical Field
The embodiments herein generally relate to a floor board of a vehicle, and more particularly, to a floor board with a plurality of predetermined shape projections to cool one or more components of the vehicle without compromising the structural strength.
Description of the Related Art
Nowadays, a battery pack, and a powertrain are manufactured in such a way which will work in an efficient manner under certain parameters. The certain parameters include, but not limited to, temperature, and pressure. Thermal explosion may occur if the battery pack, and the powertrain doesn’t meet above mentioned parameters. While travelling, the battery pack, and the powertrain are exposed to a hot atmosphere which increases the temperature of the battery pack, and the powertrain. Overheating of the battery pack, and the powertrain may lead to explosion.
In one approach, to avoid fire accidents, vehicle manufacturers use built-in cooling system to control temperature of the battery pack and the powertrain. In this approach, the built-in cooling systems uses a liquid coolant (E.g., ethylene glycol) to cool the battery pack and the powertrain. In the built-in cooling systems, a pump circulates a coolant which is a liquid through the batteries, and the powertrain, but built-in cooling makes a system complicated, and increase load of a vehicle. The built-in cooling systems are expensive so that which may affect gross price of the vehicle. In this approach, there is no way to reduce temperature of other parts of the vehicle.
Further there is need for an alternate approach to control temperature of the battery pack, the powertrain, and a controller, so that the vehicle manufacturers decided to go with a floor board with a design.
FIG. 1A illustrates an arrangement of an existing floor board 100 according to an embodiment herein. The arrangement 102 of the existing floor board 100 includes a plurality of projections 104. An air supplying arrangement provides air flow to the arrangement 102 of the existing floor board 100. The plurality of projections 104 presents to increase structural integrity of the existing floor board 100. The plurality of projections 104 reduces a flow rate of air. A reduced air flow rate fails to cool the battery pack, the powertrain, and one or more components of the vehicle.
FIG. 1B illustrates a prospective view of the existing floor board 100 with a center passage arrangement 106 according to an embodiment herein. In the existing floorboard arrangement 102, space between a battery pack and the floorboard 100 was mostly covered for structural integrity. In the existing floorboard arrangement 102, kept in the floor deck for air circulation towards the powertrain and the one or more components of the vehicle.
In the existing floor board 100, the air flow is allowed to pass through the center passage arrangement 106. Due to the center passage arrangement 106, the flow rate of air is less which fails to cool the battery pack, the powertrain, and the one or more components of the vehicle so that there remains a need for an efficient floor board arrangement to cool the battery pack, the powertrain and one or more components of the vehicle.
