Abstract

L'invention concerne un dispositif de régulation de volume d'air et de pression d'air à base de ventilateur. Un ventilateur comprend un boîtier (1), une roue (2), une entrée d'air (3), une sortie d'air (4), un dispositif de régulation d'évacuation d'air (6), un moteur à fréquence variable et un dispositif de commande, l'entrée d'air étant disposée dans la direction verticale, la sortie d'air étant disposée dans la direction horizontale, et le dispositif de régulation d'évacuation d'air étant disposé dans la sortie d'air. Le dispositif de régulation d'évacuation d'air comprend une première plaque plate (61), une seconde plaque plate (62) et un arbre de régulation pivotant (63). La première plaque plate et la seconde plaque plate sont disposées en parallèle, et ont deux extrémités dans la direction longitudinale reliées par une plaque verticale, l'arbre de régulation pivotant étant relié à la plaque verticale, et l'arbre de régulation pivotant étant relié à un mécanisme d'entraînement. L'arbre de régulation pivotant peut se déplacer linéairement par rapport à une première structure de translation. Selon la température réelle d'un transformateur, le dispositif peut réguler le volume d'air et la pression d'air du ventilateur dans une large plage de régulation de volume d'air et de pression d'air, et réalise une performance de régulation de ventilateur élevée, réduisant ainsi la consommation d'énergie du ventilateur tout en garantissant l'effet de dissipation de chaleur.
