Abstract

The present disclosure relates to improved placement, positioning, and/or orientation of radiators and baffles on a vehicle to improve and/or optimize air flow, radiator, and fuel cell performance.

First claim

What is claimed is:

1. A vehicle radiator integration system to improve fuel cell performance, comprising:
a tank storage region having one or more tanks stored therein;
one or more radiators associated with the tank storage region,
one or more baffles extending between the one or more radiators and the tank storage region,
wherein the one or more radiators and the one or more baffles are disposed above a chassis of a vehicle in an orientation that reduces hot air recirculation and air restriction,
wherein the one or more radiators or the one or more baffles are located in a gap that is located between adjacent tanks within the tank storage region.

2. The system of claim 1 , wherein the orientation of the one or more radiators is vertically parallel or is angled relative to the tank storage region.

3. The system of claim 2 , wherein an angle of the orientation of the one or more radiators is in a range of approximately 2 degrees to approximately 45 degrees.

4. The system of claim 1 , wherein the one or more baffles are disposed at a top end of the one or more radiators, a bottom end of the one or more radiators, or between the one or more radiators.

5. The system of claim 1 , wherein the orientation of the one or more baffles is substantially perpendicular or is angled relative to the tank storage region.

6. The system of claim 5 , wherein an angle of the orientation of the one or more baffles is in a range of approximately 15 degrees to approximately 75 degrees.

7. The system of claim 6 , wherein the angle of the orientation of the one or more baffles is approximately 45 degrees.

8. The system of claim 1 , wherein the one or more baffles are disposed above the tank storage region.

9. The system of claim 1 , wherein an area of the gap may extend beyond a length or a width of the chassis of the vehicle.

10. The system of claim 1 , wherein the one or more radiators are disposed or located in the gap between adjacent tanks within the tank storage region without blocking one or more valves of the one or more tanks.

11. The system of claim 1 , wherein the one or more radiators abut the tank storage region.

12. The system of claim 1 , wherein the one or more radiators are positioned in an orientation comprising an outward orientation angle or an upward orientation angle.

13. The system of claim 12 , wherein the outward orientation angle or the upward orientation angle ranges from about zero (0) degrees to about 90 degrees.

14. A vehicle radiator integration system to improve fuel cell performance, comprising:
a tank storage region disposed above a chassis of a vehicle having one or more fuel tanks stored therein;
a gap located behind or within the tank storage region comprising one or more radiators or one or more baffles,
wherein the one or more radiators are positioned at an orientation angle formed between the tank storage region and a back face of the one or more radiators that faces the tank storage region,
wherein an entirety of a top end of the one or more radiators is a first distance from the tank storage region and an entirety of a bottom end of the one or more radiators is a second distance from the tank storage region, the second distance being greater than the first distance,
wherein the one or more baffles are positioned at a baffle angle, and
wherein the orientation angle of the one or more radiators or the baffle angle of the one or more baffles improves air flow movement and heat ejection.

15. The system of claim 14 , wherein the orientation angle of the one or more radiators ranges from approximately 5 degrees to approximately 90 degrees.

16. The system of claim 14 , wherein the orientation angle of the one or more radiators is about 45 degrees.

17. The system of claim 14 , wherein the baffle angle of the one or more baffles or the orientation angle of the one or more radiators is approximately 45 degrees.

18. The system of claim 14 , wherein the one or more radiators do not abut the tank storage region.

19. The system of claim 18 , wherein the one or more baffles connect the one or more radiators with the tank storage region.

20. The system of claim 14 , wherein the one or more baffles are positioned at the top end and at the bottom end of the one or more radiators.
