Abstract
A Karman vortex street generator including a shell (), permanent magnets (), a vortex generating body (), and a metal winding (). Both ends of the shell () are respectively provided with an inlet end () and an outlet end (). The permanent magnets () are respectively located on two corresponding surfaces inside the shell (), and the N pole of the permanent magnet on one surface corresponds to the S pole of the permanent magnet on the other surface so as to form a magnet field in the shell (). The vortex generating body () is provided in the vertical center position near the inlet end () in the shell () so as to generate a Karman vortex when a fluid flows. The metal winding () located in the magnet field is able to regularly cut magnetic lines of force under the action of the Karman vortex and makes magnetic flux passing through the metal winding () change so as to generate an induction current.
