Title (EN) AXIAL-FLOW TYPE ELECTRONIC RADIATOR FAN
(FR) VENTILATEUR DE RADIATEUR ÉLECTRONIQUE DE TYPE FLUX AXIAL
(ZH) 轴流式电子散热风扇
Abstract:
(EN) An axial-flow type electronic radiator fan includes a fan blade (5) and a motor. The fan blade (5) is formed in multi-stage blade structure or single-stage blade structure. The single-stage blade structure is that all of the fan blades are formed into an integral component, or that the blades are axially cut into two sections, or that the blades are respectively arranged on several integral components. Due to the structure of the fan blade, the cascade solidity and the rated bending angle of the fan blade could be improved, the eddy current loss caused by the air flow separation on the back of the blade could be decreased, and the performance of the fan could be improved.
(FR) Un ventilateur de radiateur électronique de type flux axial comprend une ailette de ventilateur (5) et un moteur. L'ailette de ventilateur (5) est formée selon une structure d'ailette à étages multiples ou selon une structure d'ailette à un seul étage. La structure d'ailette à un seul étage se caractérise en ce que toutes les ailettes de ventilateur sont formées en un composant d'un seul tenant, ou que les ailettes sont axialement découpées en deux sections, ou que les ailettes sont respectivement agencées sur plusieurs composants d'un seul tenant. En raison de la structure de l'ailette de ventilateur, la solidité de cascade et l'angle de pliage nominal de l'ailette de ventilateur peuvent être améliorés, la perte de courant de Foucault entraînée par la séparation d'écoulement d'air sur l'arrière de l'ailette peut être diminuée, et les performances du ventilateur peuvent être améliorées.
