Abstract
(EN)
Disclosed is a wind guiding structure (200) capable of generating a wind field with three-dimensional rotational airflow. The wind guiding structure (200) comprises a plurality of air sub-channels. The air inlet (201) of an air sub-channel faces a wind source body (100), and the air outlet (202) of the air sub-channel faces an action wind area. The inner wind guiding molded line of the air sub-channel at least near the air outlet (202) is in arc shape. The wind guiding structure (200) does not need an oscillating mechanism, can form, with the blow of the wind source body (100), a flow field having straight airflows, a single airflow direction and a concentrated airflow effect, can markedly enhance the action wind area of the blow of the wind source body (100) and gentle the blow-off airflow of the wind source body (100), and can cover up one end of the wind source body (100) facing a target action wind area so that rotating blades of the wind source body (100) become an internal-mounted structure, thus eliminating the long-standing safety hazards of rotating blades and achieving a qualitative improvement of fan performances.

L'invention concerne une structure de guidage de vent (200) apte à générer un champ de vent avec un flux d'air rotatif tridimensionnel. La structure de guidage de vent (200) comprend une pluralité de sous-canaux d'air. L'entrée d'air (201) d'un sous-canal d'air fait face à un corps de source de vent (100), et la sortie d'air (202) du sous-canal d'air fait face à une zone de vent d'action. La ligne moulée de guidage de vent interne du sous-canal d'air au moins à proximité de la sortie d'air (202) est en forme d'arc. La structure de guidage de vent (200) n'a pas besoin d'un mécanisme oscillant, peut former, avec le soufflage du corps de source de vent (100), un champ d'écoulement ayant des écoulements d'air droits, une direction d'écoulement d'air unique et un effet d'écoulement d'air concentré, peut améliorer considérablement la zone de vent d'action du souffle du corps de source de vent (100) et adoucir le flux d'air de soufflage du corps de source de vent (100), et peut recouvrir une extrémité du corps de source de vent (100) faisant face à une zone de vent d'action cible de telle sorte que des pales rotatives du corps de source de vent (100) deviennent une structure à montage interne, ce qui permet d'éliminer les risques de sécurité à longue portée des pales rotatives et d'obtenir une amélioration qualitative des performances d'un ventilateur.

一种可致立体旋流风场的导风结构(200),导风结构(200)包括若干子风道;子风道的进风口(201)朝向风源体(100),子风道的出风口(202)朝向作用风域;子风道至少在靠近出风口(202)部分的内部导风型线呈弧线。该导风结构(200)无需摇头机构,可将风源体(100)的吹风建立起气流直行、气流方向单一、气流作用集中的流场,将风源体(100)吹风的作用风域显著放大和使风源体(100)的吹送气流柔化,并通过导风结构(200)对风源体(100)对于目的作用风域一端的掩盖,使得风源体(100)的旋转扇叶成为内藏结构而消除风扇旋转扇叶一贯存在的安全隐患,实现风扇性能质的提升。
