FIELD: computer engineering.
SUBSTANCE: invention is designed for use in ventilation with forced circulation of air, for instance, to cool heated elements of computer, in particular, microprocessor. Proposed device contains electric motor, axial-flow fan, ribbed radiator, and it is furnished additionally with axial-flow fan located on elongated axle under existing fan and fairing. Ribs of radiator are rectangular or cylindrical, or flat, or trapezium-like in form of truncated pyramid or truncated cone. Ribs in form of truncated cone are provided with thread. Ribs of radiator are provided with longitudinal slots in height. Blades of both axial-flow fans are made to turn through 180°.
EFFECT: increased velocity of air flow in central zone along axis.
