Patent ID: 7775062

Claim:
A modular cooling system comprising: a positive displacement compressor for pressurizing a gas to a pressure of about 0.5 to 14 pounds-force per square inch gauge pressure (psig), said positive displacement compressor having a circumferential wall; a compressor hub having an axis of rotation arranged eccentrically with respect to said circumferential wall; the hub coupled to a plurality of blades with respective blade roots; the distance between the root end of each blade and the hub axis remaining substantially constant during compressor operation; the distance between each blade tip and the hub axis cyclically changing in a substantially oscillatory fashion during compressor operation; a heat exchanger physically coupled to a semiconductor device; the heat exchanger incorporating a plurality of channels suitable for transporting the pressurized gas; each channel having an inlet, an outlet and at least one inside dimension in the range of about 5 to 50 one thousandths of an inch; a manifold in fluid communication with the channel inlets; and, the manifold operative to supply pressurized gas from the compressor to the channel inlets.
