Abstract

A heating system configured to be mounted on a motorcycle may include a food container. The heating system may further include a first coiled pipe mounted within the food container configured to heat the food container and a second coiled pipe coiled around an exhaust pipe of the motorcycle connected in fluid communication with the first coiled pipe. A working fluid may be circulated within a closed loop formed by first coiled pipe and the second coiled pipe utilizing a pumping mechanism. The working fluid may absorb heat from the exhaust pipe of the motorcycle as the working fluid flows through the second coiled pipe, and the working fluid may release the absorbed heat to the food container as the working fluid flows through the first coiled pipe.

Claims (19)

1 . A heating system for food transportation, the system comprising:

a food container configured to be mounted on a motorcycle, the food container comprising at least one inner chamber;

a first heat exchanger configured to heat the at least one inner chamber, the first heat exchanger comprising a first coiled pipe mounted within the food container;

a second heat exchanger connected in fluid communication with the first heat exchanger, the second heat exchanger comprising a second coiled pipe coiled around an exhaust pipe of the motorcycle;

a working fluid contained within the first coiled pipe and the second coiled pipe; and

a pumping mechanism configured to urge the working fluid to flow through the first coiled pipe and the second coiled pipe in a closed circulation loop,

wherein the working fluid is configured to absorb heat from the exhaust pipe of the motorcycle as the working fluid flows through the second coiled pipe, and

wherein the working fluid is further configured to release the absorbed heat to the at least one inner chamber as the working fluid flows through the first coiled pipe.

2 . The heating system of claim 1 , wherein a first end of the first coiled pipe is connected to a first end of the second coiled pipe, and a second end of the first coiled pipe is connected to a second end of the second coiled pipe via the pumping mechanism.

3 . The heating system of claim 1 , wherein the pumping mechanism is configured to urge the working fluid to flow though the first coiled pipe from the first end of the first coiled pipe toward the second end of the first coiled pipe, the pumping mechanism further configured to pump the working fluid from the second end of the first coiled pipe to the second end of the second coiled pipe, the pumping mechanism further configured to urge the working fluid to flow within the second coiled pipe from the second end of the second coiled pipe toward the first end of the second coiled pipe.

4 . The heating system of claim 3 , further comprising reservoir mounted between the second end of the first coiled pipe and the pumping mechanism, the reservoir configured to accumulate the working fluid upstream from the pumping mechanism.

5 . The heating system of claim 4 , wherein the first coiled pipe and the second coiled pipe are made of heat conducting materials.

6 . The heating system of claim 5 , wherein the second coiled pipe is coiled around a portion of the exhaust pipe between an engine of the motorcycle and a muffler of the exhaust pipe of the motorcycle.

7 . The heating system of claim 6 , wherein the second coiled pipe is in direct contact with an outer surface of the exhaust pipe of the motorcycle, and the second coiled pipe is insulated from the environment.

8 . The heating system of claim 6 , wherein the food container further comprises a first divider, the first divider configured to divide an inner volume of the food container into an exchanger housing and the at least one inner chamber, the exchanger housing configured to house the first heat exchanger.

9 . The heating system of claim 8 , wherein the food container further comprises a fan, the fan configured to circulate the air between the at least one inner chamber and the exchanger housing.

10 . The heating system of claim 9 , the at least one inner chamber comprises a heated chamber and a cold chamber, the heated chamber is in fluid communication with the exchanger housing via the fan, the cold chamber isolated from the heated chamber utilizing a second divider, the second divider comprising a heat isolating material.

11 . The heating system of claim 9 , wherein the working fluid comprises water.

12 . The heating system of claim 9 , wherein the at least one inner chamber further comprises at least one ultraviolet light source, the at least one ultraviolet light source configured to shine ultraviolet light within the at least one inner chamber.
