Patent ID: 8591206

Claim:
An apparatus, comprising: a stack of compressor vanes, wherein: said compressor vanes are responsive to electrical stimulus, and one end of each of said compressor vanes contact, and said compressor vanes are separated from each other by, thermally conductive vane spacers so that a fluid at least partially occupies a space between adjacent pairs of said compressor vanes; a heat exchanger thermally coupled to said thermally conductive vane spacers; and an electrical circuit that provides said electrical stimulus, wherein said compressor vanes: respond to said electrical stimulus by compressing and releasing said fluid between said adjacent pairs of said compressor vanes, and have a structure, contour, or geometry at one or more edges such that when said compression occurs, two or more adjacent vanes make contact, isolating a portion of the fluid that is compressed, and at least some heat of said compression is thereby transferred to said thermally conductive vane spacers.
