Abstract

A cooling system for an outdoor electronic enclosure, with separate compartments for electronics and batteries, includes separate cooling devices for each compartment so that optimal temperatures are provided to each compartment. The batteries are cooled by a thermo-electric type air-conditioner, while the electronics are cooled by direct air cooling device or a heat exchanger.

Claims

1. An outdoor electronics enclosure, comprising:

a housing;

a divider within said housing, dividing said housing into two compartments, one of said compartments being a battery compartment;

a door attached to said housing for entry into said housing; and

a cooling system for said housing, including separate cooling devices for said compartments, said cooling devices being mounted in said door and being of different types, the cooling device for the battery compartment being an air conditioner.

2. The outdoor electronics enclosure of claim 1, wherein another of said compartments houses electronics.

3. The outdoor electronics enclosure of claim 2, wherein said cooling device for the electronics compartment is a direct air cooling device.

4. The outdoor electronics enclosure of claim 3, wherein said direct air cooling device includes at least one fan.

5. The outdoor electronics enclosure of claim 3, wherein said direct air cooling device includes a filter.

6. The outdoor electronics enclosure of claim 2, wherein said cooling device for the electronics compartment is a heat exchanger.

7. The outdoor electronics enclosure of claim 1, wherein said air conditioner is a thermoelectric type air conditioner.

8. The outdoor electronics enclosure of claim 1, wherein said cooling devices are powered by direct current.

9. A hybrid cooling system for an enclosure having a plurality of compartments including a battery compartment, comprising:

a plurality of separate cooling devices having no shared components;

each of said plurality of cooling devices providing cooling to a single compartment; and

each of said cooling devices being mounted in a door to said enclosure and being of a different type, the cooling device for said battery compartment being an air conditioner.

10. The hybrid cooling system of claim 9, wherein one of said plurality of cooling devices is a direct air cooling device.

11. The hybrid cooling system of claim 9, wherein one of said plurality of cooling devices is a heat exchanger.

12. The hybrid cooling system of claim 9, wherein said air conditioner is a thermo-electric type air conditioner.

18. The hybrid cooling system of claim 9, wherein each of said plurality of cooling device cools the corresponding compartment to an optimal temperature for contents of the compartment, regardless of the temperature of other compartments.

13. A hybrid cooling system for an enclosure having a plurality of compartments including a battery compartment, comprising:

a plurality of separate cooling devices having no shared components, said plurality of cooling devices being powered by direct current;

each of said plurality of cooling devices providing cooling to a single compartment; and

each of said cooling devices being of a different type, the cooling device for said battery compartment being an air conditioner.

14. The hybrid cooling system of claim 13, wherein said air conditioner is a thermoelectric type air conditioner.

15. The hybrid cooling system of claim 13, wherein another of said compartments houses electronics, and wherein said cooling device for the electronics compartment is a direct air cooling device.

16. The hybrid cooling system of claim 15, wherein said direct air cooling device includes at least one fan and a filter.

17. The hybrid cooling system of claim 13, wherein another of said compartments houses electronics, and wherein said cooling device for the electronics compartment is a heat exchanger.
