Abstract

The present invention provides a cost effective and efficient air circulation system for a rotomolded vehicle body, comprising: at least one inlet vent disposed at the lower front of the rotomolded body assembly for receiving the air; an outlet vents comprising at least one venting vane disposed at floor of the rotomolded body assembly for receiving the air from inlet vent and disposing the air to underside of the floor for cooling of the power train system located beneath the floor. A roof of the rotomolded body assembly receiving the air from inlet vents and disposing in the void of the rotomolded body assembly for cooling the passenger area, wherein the air is forced-in from inlet vents and forced-out through the outlet vents. A high volumetric throughput pressure is maintained between inlet and outlet vents comprising the said venting vane due to position thereof.

Claims

1. Vehicle air circulation system for rotomolded body assembly (100), the system comprising;

a) a lower body frame (10) having at least one air inlet vent (6) positioned at front of the lower body frame (10) and an air channel (14) having an air outlet vent (5) comprising at least one venting vane disposed on the lower body frame (10);

b) an upper body frame (30) mounted on the lower body frame (10) having an exterior side and an interior side, an air outlet vents (5) comprising the said venting vane characterized in that the high volumetric throughput pressure is maintained between at least one air inlet vent (6) and the air outlet vent (5) by virtue of the position thereof; and

c) an air vent integrally located inside the upper body frame sandwiched between the exterior side and the interior side.

2. The Vehicle air circulation system in accordance with claim 1, wherein the air channel (14) is positioned centrally from a front side of the lower body to a rear side of the lower body.

3. The air circulation system in accordance with claim 1, wherein the air channel (14) comprises an outlet vent (5) comprising the said venting vane for underside air distribution for aid of cooling of power train system.

4. The Vehicle air circulation system in accordance with claim 1, wherein a draft of air is circulated in a passenger cabin from an underside of the air vent through the outlets having the said venting vane disposed on the upper body frame.

5. The Vehicle air circulation system in accordance with claim 1, wherein the rotomolded body assembly is made of polyethylene or polypropylene or polyamide.
