ABSTRACT:
A back-to-back double-flow bi-directional thrust-balanced micro-impeller for use in optimized compression cycles of small volumetric flow rates is provided. The back-to-back micro-impeller is a component of a compressor capable of generating a pressure head suitable for maintaining the flow rate needed for dissipating heat, such as produced by an electronic component. The back-to-back micro-impeller provides a fluid path on both sides of the micro-impeller, imparting an equal momentum (or velocity) to the fluid. The left and right compressor sections provide a balancing of forces generated by high-pressure fluid against the two sides of the micro-impeller. This reduces vibrational forces and provides a balancing force on the shaft which reduces the thrust on the shaft in a direction away from the gas flow path. Also, the approximately equally distributed mass about the rotation axis X, provides for a balanced impeller which is desirable when operated at high rotation speeds.
