Abstract

A fire suppressing device including a torus container with a main body defining an interior chamber and a discharge port, the interior chamber configured to receive and retain metal organic framework materials. The fire suppressing device also includes an inductor coil extending through the interior chamber of the torus container and surrounding the metal organic framework materials. The inductor coil is configured to heat the metal organic framework materials to form a fire suppressing substance that is conveyed through the discharge port.

First claim

The invention claimed is:

1. A fire suppressing device comprising:
a torus container including a main body defining an interior chamber and a discharge port;
metal organic framework materials disposed within the interior chamber of the torus container; and
an inductor coil extending through the interior chamber of the torus container and surrounding the metal organic framework materials;
wherein the inductor coil is configured to heat the metal organic framework materials to form a fire suppressing substance that is conveyed through the discharge port.

2. The fire suppressing device of claim 1 , wherein the discharge port is configured to couple to a fire suppressing system.

3. The fire suppressing device of claim 1 , wherein the metal organic framework materials include ferromagnetic materials and carbon dioxide pellets.

4. The fire suppressing device of claim 1 , further comprising an insulative barrier disposed within the interior chamber of the torus container between the inductor coil and the metal organic framework materials and configured to prevent shorting between the metal organic framework materials and the inductor coil.

5. The fire suppressing device of claim 4 , wherein the insulative barrier is formed from a polytetrafluoroethylene (PTFE) based material.

6. The fire suppressing device of claim 1 , wherein the torus container surrounds a central opening housing a power supply assembly coupled to the inductor coil and configured to provide current to the inductor coil.

7. The fire suppressing device of claim 6 , wherein the power supply assembly includes a battery.

8. The fire suppressing device of claim 1 , wherein the inductor coil is a toroidal coil wrapped to provide a uniform magnetic flux within the interior chamber of the torus container.

9. The fire suppressing device of claim 1 , wherein the torus container is portable.

10. A fire suppressing assembly comprising:
a flow conduit including at least one discharge nozzle;
at least one fire suppressing device coupled to the flow conduit and configured to discharge a fire suppressing substance into the flow conduit, comprising:
a torus container including a main body defining an interior chamber and a discharge port;
metal organic framework materials disposed within the interior chamber of the torus container; and
an inductor coil extending through the interior chamber of the torus container;
wherein the inductor coil is configured to heat the metal organic framework materials to form the fire suppressing substance that is discharged into the flow conduit.

11. The fire suppressing assembly of claim 10 , wherein the at least one fire suppressing device further comprises:
an insulative barrier disposed within the interior chamber of the torus container between the inductor coil and metal organic framework materials and configured to prevent shorting between the inductor coil and the metal organic framework materials.

12. The fire suppressing assembly of claim 10 , further comprising a control system configured to control the current through the inductor coil of the fire suppressing device.

13. The fire suppressing assembly of claim 12 , wherein the control system is manually controlled.

14. The fire suppressing assembly of claim 10 , wherein the inductor coil is a toroidal coil.

15. The fire suppressing assembly of claim 10 , wherein the torus container is made from a carbon fiber composite material.

16. The fire suppressing assembly of claim 10 , wherein a uniform magnetic flux is formed in the interior chamber of the torus container.

17. The fire suppressing assembly of claim 10 , further comprising a sensor assembly electrically connected to a control system configured to heat the inductor coil of the at least one fire suppressing device to heat the metal organic framework materials when smoke is detected.

18. The fire suppressing assembly of claim 10 , wherein the at least one fire suppressing device is configured to couple to an aircraft.

19. A fire suppressing device comprising:
a container including a main body defining an interior chamber;
metal organic framework materials disposed within the interior chamber of the container;
a toroidal coil extending through the interior chamber of the container and surrounding the metal organic framework materials, wherein the toroidal coil is configured to provide a uniform magnetic flux within the interior chamber when receiving current to heat the metal organic framework materials; and
an insulative barrier disposed between the toroidal coil and metal organic framework materials;
wherein the metal organic framework materials form a fire suppressing substance when heated by the toroidal coil.

20. The fire suppressing device of claim 19 , wherein the container is shaped as a torus.
