COMPRESSORS

摘要

Disclosed compressor embodiments can prevent or substantially reduce the inefficient upwardly spiraling heat buildup found in typical compressors by significantly increasing the surface area of mating piston and chamber walls, using the meshing and undulating geometry of the piston/chamber walls to create increased air turbulence in the chamber and generate more air flow against the cooling walls, promoting turbulence even more by varying the axial path of the piston head so that it is not simply linear, using fluid to cool the non-working side of the piston, and/or providing additional cooling features (such as fins) on the non-working side of the piston to provide still further cooling means for the piston head. Analogous principles can also be included in wobble-plate compressors, scroll compressors, blowers, and other compressor types.

1. A fluid compressor, which comprises:
a housing; one or more compression chambers that comprise both stationary and non-stationary walls that define the compression chambers; wherein the walls of the compression chambers are formed and structured to have at least twice the surface area that the compression chamber walls of a conventional compressor of the type has, and the stationary and non-stationary walls of the compression chambers partially or perfectly interleave or nest, or both, such that the volume of the compression chambers can be reduced sufficiently to effect a desired level of compression; wherein the walls of the compression chambers are formed and structured such that a larger portion of the fluid, compared to a conventional compressor of the type, is close to one or more walls of the compression chambers for most of the time during which the fluid is being compressed, such that said portion of the fluid is in better thermal contact with one or more walls of the compression chamber than in a conventional compressor of the type; wherein at least some of the stationary compression chamber walls are cooled by extraction of heat from said walls by, or to, one or more external heat sinks, such that said walls remain near or below the ambient temperature of the fluid to be compressed prior to entering the compressor; wherein at least some of the non-stationary compression chamber walls are cooled by extraction of heat from said non-stationary walls by fluid cooling, the extracted heat being conveyed by the cooling fluid to one or more heat sinks, which heat sinks may be external to the compressor, such that at least some of the non-stationary walls of the compressor remain near or below the ambient temperature of the fluid prior to entering the compressor; one or more compressing features that reduce the volume of the fluid that is to be compressed and thereby effect the compression of said fluid, which compressing features may be the non-stationary walls of the compression chambers, which non-stationary walls reduce the volume of the compression chambers through their motion and thereby effect the compression of the fluid wherein the one or more compressing features are cooled by extraction of heat from said compressing features by, or to, one or more heat sinks, such that said compressing features, remain near or below the ambient temperature of the fluid to be compressed prior to entering the compressor.
