ABSTRACT:
A cooling device that achieves longitudinal vortex formation, thereby reducing downstream wake, without significantly increased pressure. The device also conducts heat from the electronic component to be cooled, and includes at least one heat-conductive plate having a plurality of evenly distributed pairs of vanes that depend from the edge of the plate and flare in alternating, transverse directions. A post depends from the bottom-most plate (if the device contains more than one) and mounts directly to the component to be cooled.
