Benefits of technology

The present invention provides a cooling arrangement for a portable air compressor that offers several advantages. The components of the air compressor and power unit are arranged in a compact way, and the cooling flow is increased by providing two fans. A ducted cover with inner and outer grill areas directs the air flow from the power unit fan towards the compressor head. An opposed pair of curved walls and an air scoop smoothly transition the air flow and discharge it towards the compressor head area. Duct portions efficiently distribute the air flow and smoothly transition towards the discharge end. The technical effects of the invention include improved cooling efficiency, compact arrangement of components, and improved air flow distribution.

Problems solved by technology

Several drawbacks exist for common portable air compressor cooling assemblies.
One drawback is that common cooling configurations may not supply dedicated cooling air to the head area of the compressor.
Another drawback is that common cooling configurations have duct portions that extend over the head area of the compressor.
Another drawback with some current compressor cooling designs is that only a single fan is used and the air ducting configuration(s) is are not optimized to control the distribution of all the air flow.

Embodiment Construction

[0021] The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

[0022]FIG. 1 identifies an air compressor assembly 10 according to one preferred embodiment of the present invention. The air compressor assembly 10 includes a frame 12, a component group 14, and a pressurized fluid containment tank 16. A first wheel 18 and a second wheel 20 are rotatably supported from the frame 12 at an aft end of the air compressor assembly 10. The frame 12 includes a first side 22 and a second side 24. The first side 22 and the second side 24 are generally tubular shaped frame members substantially formed in a parallelogram configuration having rounded corners. A support plate 26 is provided at a lower portion of the frame 12 and is mechanically joined to the first side 22 and the second side 24, respectively. A pair of support feet 28 are mechanically joined to a forward end of the frame 12 at an...

Abstract

A portable air compressor assembly includes a tubular frame having side sections and an assembly longitudinal axis. A support plate between the side sections supports a power unit having a longitudinal axis arranged perpendicular to the assembly longitudinal axis. A compressor having a compressor head and longitudinal axis is mounted to the support plate with the compressor longitudinal axis parallel to the power unit longitudinal axis and perpendicular to the assembly longitudinal axis. A fan connected to the power unit generates an air flow. A ducted cover enclosing the fan includes an air passage directing the air flow from the fan to the compressor head. The ducted cover includes inner and outer covers each including a portion of the air passage. An air scoop extends into the outer cover portion of the air passage to redirect the air flow.

Description

FIELD OF THE INVENTION [0001] The present invention relates in general to air compressors and more specifically to an apparatus and method for cooling a compressor of a portable air compressor. BACKGROUND OF THE INVENTION [0002] Air compressors normally provide a source of pressurized air which is temporarily stored under pressure in a tank. A motor, typically an electric motor or a combustion engine, is connected to a compressor unit. The compressor unit typically includes a piston assembly having a piston slidably mounted in a cylinder, the piston compressing air from the atmosphere and forcing it into the fluid pressure tank for temporary storage. The work involved in compressing atmospheric air and the friction of the moving piston within the cylinder generate heat which must be dissipated. Cooling fins are commonly provided on the cylinder for air near the cylinder to convectively cool the piston assembly. Fans are also known which force air toward and about the piston assembly...
