Abstract
The invention discloses a draught fan for heat dissipation. The draught fan comprises a body, fan blades and supporting parts. The body comprises a protruding part and a plane part. The fan blades are of a stereoscopic structure, the lower surfaces of the fan blades are in a paddle shape, the narrow ends of the fan blades are close to the protruding part, and two opposite inclined surfaces forming a 4-degree included angle with the vertical surface are arranged at the end, close to the protruding part, of the upper surface of each fan blade. The supporting parts cover the plane part away from the protruding part and are connected to the side surface of the protruding part in an abutting mode. According to the draught fan for heat dissipation, the supporting parts are used for supporting the draught fan and do not completely cover the body, and thus the fan blades arranged on the side surface of the protruding part are not covered by the supporting parts so that hot air can be discharged from all sides with the cooperation of the fan blades distributed on the side surface of the protruding part in a radiation mode in the circumferential direction, the air mobility is enhanced, and the heat dissipating performance of the draught fan is improved.
