Abstract

An electrical enclosure is disclosed for use with a mobile machine having a cabin. The electric enclosure may have a plurality of compartments configured to house a plurality of different electrical components. The electrical enclosure may also have a duct formed within a first of the plurality of compartments located below a floor of the cabin. The duct may be configured to receive conditioned air from the cabin and to direct the conditioned air from a second of the plurality of compartments into the first of the plurality of compartments.

First claim

What is claimed is:

1. An electrical enclosure for a mobile machine having a cabin, the electrical enclosure comprising:
a plurality of compartments configured to house a plurality of different electrical components; and
a duct formed within a first of the plurality of compartments located below a floor of the cabin, the duct configured to receive conditioned air from the cabin and to direct the conditioned air from a second of the plurality of compartments into the first of the plurality of compartments,
wherein the second of the plurality of compartments includes a ventilated door configured to allow the flow of conditioned air to exit the cabin and enter the electrical enclosure.

2. The electrical enclosure of claim 1 , wherein the duct includes:
an opening formed in a door of the first of the plurality of compartments; and
a passage located at the floor of the cabin and connecting the first and second of the plurality of compartments.

3. The electrical enclosure of claim 1 , wherein the plurality of different electrical components includes at least one of a signal conditioner, an electric power supply, communication equipment, and a control board located within the second of the plurality of compartments.

4. The electrical enclosure of claim 1 , further including a filter disposed within the ventilated door, in a flow path of the conditioned air.

5. The electrical enclosure of claim 1 , wherein the filter is disposed at an angle relative to a flow direction of the conditioned air.

6. The electrical enclosure of claim 1 , wherein:
the plurality of compartments includes a ventilated third compartment; and
the plurality of different electrical components includes a resistor grid mounted within the third compartment that is configured to transfer heat with an ambient atmosphere below the floor of the cabin.

7. The electrical enclosure of claim 6 , wherein the third compartment is located adjacent the first of the plurality of compartments.

8. The electrical enclosure of claim 7 , wherein:
the plurality of compartments includes a fourth compartment stacked on top of the third compartment and located adjacent the second of the plurality of compartments;
the plurality of different electrical components includes at least one of a multiplex connector, a power distribution connector, a circuit module, a relay, and a TDP board mounted within the fourth compartment; and
the fourth compartment is fluidly connected with the second of the plurality of compartments.

9. The electrical enclosure of claim 8 , wherein:
the plurality of compartments includes a fifth compartment stacked on top of the second of the plurality of compartments and horizontally adjacent the fourth compartment;
the plurality of different electrical components includes a panel of circuit breakers mounted within the fifth compartment; and
the fifth compartment is substantially isolated from the remaining of the plurality of compartments.

10. The electrical enclosure of claim 1 , wherein:
the second of the plurality of compartments is about twice as big as each of the remaining of the plurality of compartments; and
the remaining of the plurality of compartments are all about the same size.

11. The electrical enclosure of claim 1 , wherein:
each of the plurality of compartments includes a door; and
the plurality of different electrical components includes an operator interface device mounted within the door.

12. The electrical enclosure of claim 1 , further including an opening in a back wall forming a conduit for an electrical wire.

13. A cabin for a mobile machine, comprising:
a floor;
a ceiling;
a front wall connecting the floor to the ceiling;
a left side wall connecting the floor to the ceiling;
a right side wall connecting the floor to the ceiling; and
an electrical enclosure forming a back wall that connects the floor to the ceiling and the left side wall to the right side wall, the electrical enclosure having at least a first compartment located below the floor and at least a second compartment located above the floor,
wherein the at least a second compartment includes a ventilated door configured to direct conditioned air from the cabin into the at least a second compartment.

14. The cabin of claim 13 , wherein the floor, ceiling, front wall, left side wall, right side wall, and electrical enclosure are welded together.

15. The cabin of claim 14 , wherein the at least a first compartment forms a duct configured to direct conditioned air from the at least a second compartment to below the floor.

16. The cabin of claim 14 , further including a filter disposed within the at least a second compartment.

17. The cabin of claim 14 , wherein the electrical enclosure includes a third compartment configured to house a resistor grid and being ventilated to a space below the floor.

18. A locomotive, comprising:
a plurality of wheels configured to engage a track;
a base platform supported by the plurality of wheels;
a power module mounted to the base platform; and
a cabin located forward of the power module and having an electrical enclosure that forms a back wall of the cabin and spaces the cabin away from the base platform, wherein the electrical enclosure includes:
a first compartment forming a duct and being configured to receive conditioned air from a space above a floor of the cabin and above the base platform;

a second compartment located above the floor and in fluid communication with the first compartment, the second compartment having a ventilated door in the cabin; and
a filter disposed within the first compartment.
