Abstract

Gas concentrating systems and methods are provided. In one embodiment, a gas concentrating system and method is provided that includes component heat management. The heat management system can include, for example, one or more air cooling paths. The air cooling paths direct cooling air into and out of component spaces having heat-generating mechanisms. In other embodiments, the heat management system can also include component spaces that are insulated against the heat of heat-generating components. By cooling heat-generating components and insulating other components from heat, reduced wear and extended component life can be achieved. This reduces component failure and costly service to repair or replace failed or worn components. Also, gas concentrating systems and methods are provided for mounting system components with or without the use fasteners and in combination with or without component heat management.

First claim

What is claimed:

1. A method of operating a gas concentrating system comprising:
providing cooling air into a compressor space through first and second spaced apart air inlets;
generating a first air cooling path for cooling an external portion of a compressor head portion through the first inlet;
generating a second air cooling path for cooling a compressor motor portion through second inlet;
generating a third air cooling path for cooling a compressor output duct portion via a third air inlet; and
exhausting the cooling air away from the compressor head and motor portions.

2. The method of claim 1 , wherein generating a first air cooling path comprises directing cooling air across the compressor head portion.

3. The method of claim 1 , wherein generating a second air cooling path comprises directing cooling air across the compressor motor portion.

4. The method of claim 1 wherein generating the first air cooling path for cooling the compressor head portion through the first inlet comprises generating the first air cooling path closer to the compressor head portion than the motor portion.

5. The method of claim 1 wherein generating the second air cooling path for cooling the compressor motor through the second inlet comprises generating the second air cooling path closer to the compressor motor portion than the head portion.

6. The method of claim 1 wherein generating the third air cooling path for cooling the compressor output duct portion via the third air inlet comprises generating the third air cooling path closer to the compressor output duct portion than the head portion.

7. The method of claim 1 wherein exhausting the cooling air away from the compressor head and motor portions comprises directing the air along an exhaust path that is insulated from the compressor space.

8. The method of claim 1 wherein exhausting the cooling air away from the compressor head and motor portion comprises directing the cooling air along an exhaust path exiting away from a front portion of the gas concentrating system.

9. The method of claim 1 wherein exhausting the cooling air away from the compressor head and motor portion comprises directing the cooling air along an insulated exhaust path exiting away from a top portion of the gas concentrating system.

10. A method of cooling a gas concentrating system comprising:
providing a cooling airstream from at least one air intake;
directing at least a first portion of the cooling airstream into at least a first inlet of a compressor space and to an external portion of a head portion of a compressor;
directing at least a second portion of the cooling airstream into at least a second inlet of the compressor space and to a motor portion of the compressor;
directing at least a third portion of the cooling airstream into at least a third inlet of the compressor space and to a compressor output duct space; and
exhausting the first and second portions of the cooling airstream away from the head and motor portions of the compressor.

11. The method of claim 10 wherein exhausting the first and second portions of the airstream away from the head and motor portions of the compressor comprises directing the airstream along an exhaust path that is insulated from the compressor space.

12. The method of claim 10 wherein directing the third portion of the airstream into the compressor output duct space comprises directing the third portion of the cooling airstream into a compressor duct space that is isolated from the compressor space.

13. A method of cooling a gas concentrating system comprising:
providing an internal mounting body and an external housing;
providing an airstream from at least one air intake and into first and second passageways between the internal mounting body and external housing;
directing a portion of the airstream in the first passageway into at least a first inlet of the mounting body and into the second passageway;
directing another portion of the airstream in the second passageway into at least a second inlet of the mounting body;
directing portions of the airstream in the second passageway into at least a third passageway and a third inlet of the mounting body; and
exhausting portions of the airstream from the mounting body.

14. The method of claim 13 wherein directing the portion of the airstream in the first passageway into at least the first inlet of the mounting body comprises directing the portion of the airstream in the first passageway closer to a head portion of a compressor than a motor portion.

15. The method of claim 13 wherein directing the portion of the airstream in the second passageway into at least the second inlet of the mounting body comprises directing the portion of the airstream in the second passageway closer to a motor portion of a compressor than a head portion.

16. The method of claim 13 wherein directing portions of the airstream in the second passageway into at least the third passageway and the third inlet of the mounting body comprises directing portions of the airstream from the third inlet to at least one output duct of a compressor.

17. The method of claim 13 further comprising directing portions of the airstream entering the third inlet into an output duct space that is insulated from a compressor space.
