Abstract

A vehicle including a vehicle body, an air conditioning unit, and a fairing. The vehicle body includes a roof having a front portion and a rear portion. The air conditioning unit is disposed within the vehicle body and includes a condenser configured to receive air from outside the vehicle body through an opening in the rear portion of the roof. The fairing is disposed over the rear portion of the roof and the opening thereby defining an interior volume between the fairing and the rear portion of the roof. The fairing includes a leading portion oriented toward the front portion of the roof. The leading portion has an air inlet such that when the vehicle moves in a forward direction air from outside the vehicle body enters the interior volume through the air inlet, passes through the opening, and passes through the condenser.

First claim

What is claimed is:

1. A fairing for a vehicle including a vehicle body having a roof, the vehicle including an air conditioning unit disposed within the vehicle body, the air conditioning unit including a condenser configured to receive air from outside the vehicle body through an opening of the roof, the fairing comprising:
a top portion including a front edge, a rear edge opposing the front edge, and two opposing side edges, wherein the top portion has a curved arc shape extending from the front edge to the rear edge,
a leading portion including a first portion and a second portion, the first portion extending from one of the two opposing side edges of the top portion past the front edge of the top portion, and the second portion extending from the other of the two opposing side edges of the top portion past the front edge of the top portion, wherein
the first portion, the second portion, and the front edge define an air inlet configured to allow air to pass into an interior volume under the top portion, the air inlet is located along a front portion of the fairing, and
wherein the fairing is configured to be disposed over the opening in the roof of the vehicle body to direct at least a portion of the air passing into the interior volume into the opening in the roof of the vehicle body when the fairing is disposed over the roof of the vehicle body.

2. The fairing of claim 1 , wherein the fairing is configured to be disposed over a rear portion of the roof such that the interior volume is located between the fairing and the rear portion of the roof, each of the first portion and the second portion extends from a respective one of the two opposing side edges of the top portion towards a front portion of the roof, and when the vehicle moves in a forward direction air from outside the vehicle body enters the interior volume through the air inlet, passes through the opening in the roof, and passes through the condenser.

3. The fairing of claim 1 , wherein the top portion includes an air outlet such that when the vehicle moves in a forward direction air from outside the vehicle body enters the interior volume through the air inlet and a portion of the air exits the fairing through the air outlet.

4. The fairing of claim 1 , wherein
the area of the air inlet is greater than the area of an air outlet, and
the air inlet is a single opening defined by the front edge, the first portion and the second portion.

5. The fairing of claim 1 , wherein the curved arc shape includes a front up-slope portion starting from the front edge, the front up-slope portion extending upwardly as it extends from the front edge in a direction towards the rear edge.

6. The fairing of claim 1 , wherein the curved arc shape includes a rear up-slope portion starting from the rear edge, the rear up-slope portion extending upwardly as it extends from the rear edge in a direction towards the front edge.

7. The fairing of claim 5 , wherein the air inlet is positioned entirely on the front up-slope portion.

8. The fairing of claim 3 , wherein
the curved arc shape includes:
a front up-slope portion starting from the front edge, the front up-slope portion extending upwardly as it extends from the front edge in a direction towards the rear edge, and
a rear up-slope portion starting from the rear edge, the rear up-slope portion extending upwardly as it extends from the rear edge in a direction towards the rear edge, and

the air outlet is positioned on the front up-slope portion and the rear up-slope portion.

9. The fairing of claim 1 , wherein the first portion and the second portion are separated by the air inlet.

10. The fairing of claim 1 , wherein the fairing has a front leading edge, the front leading edge comprising an edge of the first portion, an edge of the second portion, and the front edge of the top portion.
