Abstract: A fan blade structure applied to a centrifugal fan is provided. The fan blade structure includes a wheel hub and an annular vane. The wheel hub includes a plurality of connecting brackets, and the annular vane includes multiple crests and troughs which interlace to form a continuous curved surface. The continuous curved surface has an outer ring surface and an inner ring surface. The connecting brackets are connected to the inner ring surface and drive the annular vane to rotate.

Abstract: A heat dissipation component includes a first film, a second film, and a working fluid. The second film is connected with a part of the first film to form a plurality of vein channels. The vein channels include a main vein channel and a plurality of branch vein channels, and the main vein channel is connected with the branch vein channels. The working fluid is disposed in the vein channels. The heat dissipation component is bendable to be easily assembled with an electronic device. The working fluid may flow in the vein channels via a pressure difference generated by a phase transition, gravity, and a capillary effect, or via a pressure difference generated, by a pulse generator to transfer the heat to the whole heat dissipation component. The first film and the second film may have heat conduction material to improve the heat transfer rate.
