Abstract
A device for generating a flow of air, particularly for cooling electronic components, with an annular piezo element and an emitter element, wherein the annular piezo element can be vibrated radially by applying an alternating voltage, the emitter element is coupled radially to the annular piezo element, and wherein the radial vibration of the annular piezo element is configured so as to set the emitter element into axial vibration to generate the air flow which thereby permits a device of small dimensions for generating the an air flow to be created that is simultaneously characterized by low energy consumption and a long service life.
