Summary of mini air compressor
An air supply system having a multi-cylinder, two-stage mini air compressor including a pair of low pressure cylinders and a high pressure cylinder. A first intercooler interconnected between the outlet of one of the pair of low pressure cylinders and the inlet of the high pressure cylinder and a second intercooler interconnected between the outlet of the other of the pair of low pressure cylinders. An aftercooler connected to the outlet of the high pressure cylinder for effectively reducing the temperature of the compressed air supplied to a storage reservoir to near or at ambient temperature. A protective housing including a frontal screened opening for permitting a rotary fan to draw cooling air into the housing and including an internal shroud for directing the cooling air over the intercoolers and aftercooler.
1. A multi-cylinder, two-stage, mini air compressor comprising, at least one low pressure cylinder and at least one high pressure cylinder, an intercooler connected between said low and high pressure cylinders, an aftercooler connected to the outlet of said high pressure cylinder, a cooling fan having blades and a hub connected to and driven by the shaft of the mini air compressor, a protective housing, a screened opening and a shroud, said screened opening and shroud directing air through said intercooler and said aftercooler for effectively cooling the compressed air so that the temperature of the delivered air approaches that of the atmospheric ambient temperature, the diameter of said fan blades is substantially equal to that of said screened opening and the tips of said fan blades coming within a fraction of an inch of the inner periphery of said shroud in order to minimize air turbulance and maximize air flow.
2. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein said shroud is a cylindrical member secured to the inside of said protective cover.
3. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein said protective housing is a metallic box-like structure placed over the exposed end of the mini air compressor.
4. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein the mini air compressor includes a pair of low pressure cylinders and a single high pressure cylinder.
5. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein said aftercooler includes an inlet header and an outlet header interconnected by a plurality of finned core tubes.
6. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein said protective housing is a fabricated sheet metal structure.
7. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein the cooled compressed air is supplied to a storage reservoir.
8. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein said intercooler includes an inlet header interconnected to a common header by a first plurality of finned core tubes and includes an outlet header interconnected to said common header by a second plurality of finned core tubes.
9. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein said shroud is a flanged, cylindrical member which is bolted to the inside of said protective cover.
10. The multi-cylinder, two-stage mini air compressor as defined in claim 1, wherein said intercooler and said aftercooler are fabricated of fin core of aluminum structure.
11. An mini air compressor comprising, a first and second low pressure cylinder and a high pressure cylinder, a first intercooler interconnected from the outlet of said first low pressure cylinder to the inlet of said high pressure cylinder, a second intercooler interconnected from the outlet of said second low pressure cylinder to the inlet of said high pressure cylinder, a bladed cooling fan driven by the crankshaft of the mini air compressor, an aftercooler interconnected from the outlet of said high pressure cylinder to the inlet of an air storage reservoir, a protective enclosure covering said fan and having an intake opening, a screen and a cylindrical shroud encompassing said screened opening for directing cooling air over said first and second intercoolers and said aftercooler for effectively dissipating the heat of the compressed air so that the temperature of air supplied to said air storage reservoir is near atmospheric ambient temperature, said screened opening having a diameter substantially equal to the diameter of said fan and the tips of the fan blades extending within a fraction of an inch of the inner periphery of said cylindrical shroud to minimize air turbulance and maximize air flow.
12. The mini air compressor as defined in claim 11, wherein said protective enclosure is a skirted sheet metal box-like structure.
13. The mini air compressor as defined in claim 11, wherein said first and second inner cooler each include an inlet header interconnected to a common header by a first fin core structure and include an outlet header interconnected to said common header by a second fin core structure.
14. The mini air compressor as defined in claim 13, wherein said aftercooler includes an inlet header interconnected to an outlet header by a fin core structure.
15. The mini air compressor as defined in claim 11, wherein said fan draws the air through said intake opening, said screen, and said inner cylindrical shroud for directing the air over said intercoolers and said aftercooler.
16. The mini air compressor as defined in claim 11, wherein said fan includes a hub bolted to said crankshaft and a circular plate having a plurality of blades attached to the periphery thereof.
17. The mini air compressor as defined in claim 11, wherein said first and second intercoolers are disposed in side-by-side relationship with each other and said aftercooler is disposed below said first and second intercoolers.
18. The mini air compressor as defined in claim 11, wherein said cylindrical shroud includes a flat circular flange welded to one end thereof.
19. The mini air compressor as defined in claim 18, said screen is sandwiched between said flat circular flange and the inside surface of said protective enclosure for covering said intake opening.
20. The mini air compressor as defined in claim 11, wherein said protective enclosure includes a plurality of gridded outlets to allow for the dissipation of heat.
