Problems solved by technology

Yet another defect that exists in some common compressor cooling structures is that only a single fan is used and the design of the air duct structure (one or more) cannot control the entire airflow distribution to an optimum state

Embodiment Construction

[0022] The following description of preferred embodiments is merely exemplary in nature and not limiting of the invention and its application or uses.

[0023] figure 1 An air compressor unit 10 of a preferred embodiment of the present invention is shown. The air compressor assembly 10 includes a frame 12 , a component group 14 , and a pressurized fluid container 16 . A first wheel 18 and a second wheel 20 are rotatably supported on the frame 12 at the aft end of the air compressor unit 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 frame members in the form of a substantially rounded parallelogram configuration. Support plates 26 are provided at the lower portion of the frame 12 and are mechanically connected to the first side 22 and the second side 24, respectively. A pair of legs 28 are mechanically connected to the front end of frame 12 at the underside of support plate 26 . Frame 12 is ...

Abstract

The invention discloses 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. Every parts can be assembled compactly according to the structure in the invention. More cooling air is provided to the compressor by setting the two fans. The ducted cover can induct and keep the air flow to the compressor head invariable basically.

Description

technical field [0001] The present invention relates generally to air compressors and, more particularly, to an apparatus and method for cooling the compressor in a portable air compressor. Background technique [0002] Air compressors typically provide a source of pressurized air that is temporarily stored in a pressure vessel. An engine, usually an electric motor or an internal combustion engine, is connected to the compressor unit. Compressor units typically include a piston assembly having a piston slidably mounted within a cylinder that compresses air from the environment and forces the compressed air into a fluid pressure vessel for temporary storage. Both the work done in compressing the ambient air and the friction caused by the piston moving within the cylinder generate heat that must be dissipated. There are generally cooling fins on the cylinder, which use the air convection around the cylinder to cool the piston assembly. To enhance convective cooling, fans ar...
