  • Patent number: 7891410
    Abstract: 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.
