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 mounting body for a gas concentrating system comprising:
a plurality of spaces including a compressor space for housing a compressor and a fan space for housing at least one fan; the compressor comprising a motor portion and a head portion; the compressor space comprising at least first and second air inlets and an outlet;
the first air inlet substantially aligned with the compressor head portion;
the second air inlet substantially aligned with the compressor motor portion; and
the outlet substantially aligned with the compressor head portion; and
wherein cooling air is drawn through the at least first and second inlets into the compressor space and out the outlet.

2 . The mounting body of claim 1 , wherein the compressor space includes an air cooling path between the first inlet and the outlet and across the compressor head portion.

3 . The mounting body of claim 1 , wherein the compressor space includes an air cooling path between the second inlet and the outlet and across the compressor motor portion.

4 . The mounting body of claim 1 , wherein the compressor space includes a first air cooling path between the first inlet and the outlet and a second air cooling path between the second inlet and the outlet.

5 . The mounting body of claim 1 , wherein the compressor space includes a at least a third inlet substantially aligned a compressor output duct space.

6 . The mounting body of claim 1 , wherein the plurality of spaces further comprise a valve space having a plurality of walls insulating the valve space from the compressor space.

7 . The mounting body of claim 1 , wherein the plurality of spaces further comprise a sieve bed space for at least partially receiving one or more sieve beds.

8 . The mounting body of claim 1 , wherein the plurality of spaces further comprise a product tank space for at least partially receiving at least one product tank.

9 . The mounting body of claim 1 , wherein the plurality of spaces further comprise a compressor output duct space.

10 . The mounting body of claim 1 , wherein the compressor space comprises a plurality of walls and a gap between the plurality of walls and the compressor.

11 . A gas concentrating system comprising:
a mounting body for a gas concentrating system, the mounting body having a plurality of spaces including:
an internal compressor space for housing a compressor;
an internal valve space for housing at least one valve;
an external sieve bed space for at least partially housing one or more sieve beds; and
an external product tank space for at least partially housing one or more product tanks.

12 . The system of claim 11 , wherein the mounting body comprises a plurality of cooling air inlets and at least one outlet.

13 . The system of claim 11 , wherein the compressor space comprising at least a first air inlet substantially aligned with a compressor head portion and a second air inlet substantially aligned with a compressor motor portion.

14 . The system of claim 11 , wherein the mounting body further comprises at least one air cooling path for cooling a compressor head portion.

15 . The system of claim 11 , wherein the mounting body further comprises at least one air cooling path for cooling a compressor motor portion.

16 . The system of claim 11 , wherein the mounting body further comprises at least a first air cooling path for cooling a compressor head portion and at least one air cooling path for cooling a compressor motor portion.

17 . A method of operating a gas concentrating system comprising:
drawing cooling air into a compressor space through first and second spaced apart air inlets; generating a first air cooling path for cooling a compressor head portion through the first inlet; generating a second air cooling path for cooling a compressor motor through second inlet; and exhausting the cooling air away from the compressor head and motor portions.

18 . The method of claim 17 , wherein generating a first air cooling path for comprises directing cooling air across the compressor head portion.

19 . The method of claim 17 , wherein generating a second air cooling path comprises directing cooling air across the compressor motor portion.

20 . The method of claim 17 further comprising generating a third air cooling path for cooling a compressor output duct portion via a third air inlet.
