1. A method of cooling electronic components within a cabinet comprising the steps of:

  • enclosing at least one predetermined heat generating electronic component inside a cabinet to isolate it from other electronic components in the cabinet;

    providing an isolated air flow pathway to conduct air from the cabinet exterior, across the enclosed heat generating electronic component, and exhaust the air to the cabinet exterior, said isolated air flow pathway being isolated from ambient air inside the cabinet;

    providing turbulence inducing means in said isolated air flow pathway at one end of the enclosed heat generating electronic component, andconducting air through said isolated air flow pathway and across said turbulence inducing means such that the turbulent air flows across the enclosed heat generating electronic component, wherebythe enclosed heat generating electronic component is cooled independently of the non-isolated components and the heat generated by the enclosed heat generating electronic component and the non-isolated components is not mixed within the cabinet to maximize cooling of all components within the cabinet, andthe turbulent air flow prevents the formation of a laminar boundary layer of air on the surface of the enclosed heat generating electronic component to maximize heat transfer.
