This invention discloses an electronic apparatus comprising a soleplate, a row of fans fixed on the soleplate, a wind scooper and a circuit board. The wind inlet of the wind scooper formed by a rotation cover and two extension parts faces and is close to the fans. The circuit board is provided with a plurality of electronic members which are arranged in the wind scooper and vertical cards which are positioned behind the wind scooper, the vertical cards are provided with expansion cards which are higher than base body. The wind scooper comprises a base body, a rotation cover and a positioning member. The base bodycomprises a framework body and two extension parts. The framework body comprises a top plate and two side plates extending downwardly from the two sides of the top plate; the rotation cover comprises a top cover and two side covers extending downwardly from two sides of the top cover and abutting against the inner sides of the two extension parts; and the back end of the rotation cover is connected to the framework body in a rotation manner. The electronic device can rotate the rotation cover according to the radiation requirement of the expansion cards on the vertical cards of the circuit board in order to ensure that the expansion card obtains appropriate wind flow, and the wind flow distribution of the fans can be arranged properly.
