Abstract: An electronic device is provided. The electronic device includes a first body, a second body, and a baffle structure. The first body includes a first edge. The second body includes a second edge. The first edge is pivotally connected to the second edge, and an air outlet is provided on the second edge. An air duct is formed between the first edge and the second edge. The baffle structure is disposed in the air duct and located at a position corresponding to the air outlet. The baffle structure selectively closes the air duct according to a temperature of the air outlet, to avoid a rising temperature inside the electronic device due to hot air backflow.

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 fan module is disclosed. The fan module comprises a casing, a fan and a plurality of fins. The casing has a mounting space, an air inlet and an air outlet. The air inlet and the air outlet are linked through the mounting space. The fan is installed inside the mounting space. The fins are installed across the air outlet with each fins aligned in parallel to each other. The fins have a plurality of protruding sections protruding from a surface of the fins. Neighboring fins are separated from each other through the protruding sections so that the fins altogether divide the air outlet into a plurality of slots whose width is less than or equal to 1 mm.

Abstract: A fan module comprising a housing, a fan and a plurality of fins is provided. The housing has a mounting space, an air inlet and a corresponding air outlet. The mounting space links the air inlet to the air outlet. The fan is installed within the mounting space. The fins are aligned in parallel and fitted inside the air outlet. The fins divide the air outlet into a plurality of parallel slots, each of which has width less than or equal to 1 mm.
