Abstract[English]
A fan blade having an air-funnel structure. By providing a plurality of embedded air funnels on the blade, and on the basis of the effect of the increase in flow velocity due to the change in the cross-section of an airflow channel, the cooling capability of the fan is significantly enhanced. The fan blade can not only provide a more comfortable use experience, but also achieve good energy saving and noise reduction effects, and meets the air circulation and temperature regulation requirements under various environmental conditions.[French]
L'invention concerne une pale de ventilateur ayant une structure d'entonnoir à air. En fournissant une pluralité d'entonnoirs à air intégrés sur la pale, et sur la base de l'effet de l'augmentation de la vitesse d'écoulement due au changement de la section transversale d'un canal d'écoulement d'air, la capacité de refroidissement du ventilateur est significativement améliorée. La pale de ventilateur peut non seulement fournir une expérience d'utilisation plus confortable, mais également parvenir à de bons effets d'économie d'énergie et de réduction du bruit, et satisfait aux exigences de circulation d'air et de régulation de température sous diverses conditions environnementales.[Chinese]
一种具有风漏斗结构的风扇扇叶，通过在扇叶上设置多个嵌入式风漏斗，利用气流通道截面变化引起的流速增加效应，显著提高了风扇的降温能力，其不仅能够提供更加舒适的使用体验，而且具备良好的节能降噪特性，适用于多种环境条件下的空气流通与温度调节需求。
