A device and method that exchanges heat is described, which includes intaking air into a chamber and then forcing air from holes of a heat conducting surface that fluidly communicate with the chamber to create a toroidal mass of air resulting from vortex shedding. A pump, for example a flexible diaphragm, is employed to increase and decrease a volume of the chamber in communication with the holes. When the volume of the chamber is increased (air intake), a boundary layer of heat breaks up by the heat conducting surface which helps to improve cooling. When the volume of the chamber is decreased, jets of air are discharged from the holes to create vortices of air that cause vortex shedding and can also help disrupt the boundary layer of heat.

The invention claimed is: 1. A heat exchange device comprising:a heat conducting surface, the heat conducting surface configured to have a boundary layer of heat therearound, the heat conducting surface including at least one hole extending therethrough generally perpendicular to the heat conducting surface;a pump connected to the heat conducting surface;a chamber between the heat conducting surface and the pump, the chamber having a volume which can increase and decrease to cause a jet of air to be discharged through the hole when the pump is moved; anda driver mechanism configured to move the pump to cause increases and decreases in the volume of the chamber as the pump moves;the hole, pump, chamber, and driver mechanism are configured to cooperate to draw air into the chamber which disrupts the boundary layer of heat and are configured to cooperate to expel air from the hole to further disrupt the boundary layer and to dissipate heat by vortex shedding through the boundary layer of heat.
