Modular cooling system

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;
• the manifold operative to supply pressurized gas from the compressor to the channel inlets;
• a compressor mounted filter frame and a filter coupled to the frame;
• the filter operative to restrict passage of contaminants with a mean diameter of at least 25 one thousandths of an inch;
• a collector in fluid communication with the channel outlets;
• a conduit in fluid communication with the collector;
• and,
• the conduit operative to transport gas exhausted from the heat exchanger across a physical boundary separating two spaces, one of which spaces is a temperature controlled space suited for human occupancy.
