CLAIMS

WHAT IS CLAIMED IS:

1. A fuel tank comprising:

a fuel storage chamber having a fuel storage chamber wall defining an interior volume; and

a heatsink coupled to the fuel storage chamber wall, the heatsink comprising an interior heatsink portion disposed within the interior volume of the fuel storage chamber and an exterior heatsink portion exposed to an exterior of the fuel storage chamber wall to facilitate heat transfer between the interior volume and the exterior of the fuel storage chamber wall;

a fuel inlet coupled to the fuel storage chamber wall; and

a flow modification element coupled to the fuel inlet,

wherein the flow modification element and the heatsink combine to reduce heat generated by filling of the fuel tank.

2. The fuel tank of claim 1, wherein the fuel inlet is disposed on a first side of the fuel storage chamber wall and the heatsink is disposed on a second side of the fuel storage chamber wall.

3. The fuel tank of claim 1, wherein the flow modification is disposed at least partially within the interior volume of the fuel storage chamber when coupled to the fuel inlet.

4. The fuel tank of claim 3, wherein the flow modification element is configured to outlet the fluid into a middle portion of the interior volume of the fuel storage chamber when the fuel storage chamber is filled with the fuel.

5. The fuel tank of claim 1, wherein the flow modification element is removably attached to the fuel inlet.

6. The fuel tank of claim 5, wherein the flow modification element is configured to direct the fuel to flow in a vortex manner within the interior volume of the fuel storage chamber.

7. The fuel tank of claim 1, wherein the interior heat sink portion is integral with the exterior heat sink portion.

8. The fuel tank of claim 1, wherein the heatsink further comprises a heatsink wall portion coupling the interior heatsink portion with the exterior heatsink portion, the heatsink wall portion being coupled to the fuel storage chamber wall.

9. The fuel tank of claim 1, wherein the interior heatsink portion comprises at least one interior fin.

10. The fuel tank of claim 1, wherein the exterior heatsink portion comprises at least one exterior fin.

11. The fuel tank of claim 1, wherein the fuel storage chamber is configured to store and maintain pressure for compressed natural gas (CNG).

12. A system for storing fuel, the system comprising:

the fuel tank of claim 1 ; and

an active cooling element for cooling the exterior heatsink portion, wherein the active cooling element comprises at least one of a fluid bath, a fan, or a coolant system.

13. A method of filling a fuel tank with fuel, the method comprising:

providing a fuel tank comprising a fuel inlet, a fuel storage chamber having a wall defining an interior volume, and a heatsink coupled to the wall, the heatsink being disposed within the interior volume and exposed to an exterior of the wall;

introducing fuel into the interior volume through the fuel inlet, wherein introducing the fuel generates a heat of compression; and

directing, with the heatsink, at least a portion of the generated heat of compression from the interior volume to the exterior of the wall of the fuel storage chamber, wherein introducing fuel into the interior volume comprises channeling the fuel through a flow modification element,

wherein the heatsink and the flow modification element combine to reduce heat generated by filling of the fuel tank.

14. The method of claim 13, wherein channeling the fuel through the flow modification element causes the fuel to flow into the interior volume in a vortex manner.

15. The method of claim 13, wherein channeling the fuel through the flow modification element comprises introducing the fuel into a middle portion of the interior volume.

16. The method of claim 13, further comprising coupling the flow modification element to the fuel inlet.

17. A method of filling a fuel tank with fuel, the method comprising:

providing a fuel tank comprising a fuel storage chamber having a wall defining an interior volume and a fuel inlet positioned at least partially within the interior volume; and introducing fuel into the interior volume through the fuel inlet,

wherein the fuel is directed through a plurality of outlet perforations of the fuel insert into the interior volume, the plurality of outlet perforations reducing noise generated by the introduction of the fuel into the interior volume, and

wherein introducing fuel through the fuel inlet modifies the flow of the fuel to reduce heat generated by filling of the fuel tank.

18. The method of claim 17, wherein the fuel inlet comprises an elongate tube positioned within the interior volume of the fuel tank.

19. The method of claim 18, wherein the plurality of perforations is distributed at least one of axially along a length of the elongate tube or circumferentially about a longitudinal axis of the elongate tube.

20. The method of claim 18, wherein the fuel storage chamber is configured to store and maintain pressure for compressed natural gas (CNG).
