Abstract

The invention discloses a blade of a louver, and further discloses the louver comprising the blade. The blade of the louver comprises a blade body, a plurality of vortex generators are arranged on theair flow surface of the blade body, each vortex generator comprises flow dividing plates, the bottom ends of the flow dividing plates are mounted on the air flow surface and extend outward, and the front ends in the length extension directions of the flow dividing plates face the direction of air advancement on the air flow surface. The pressure loss of the entire louver is small, the noise pollution caused by airflow is reduced, the thickness of the blade body is increased, and low frequency attenuation is improved; and moreover, the blade body can be arranged at a higher angle to improve the high frequency performance, and the aerodynamic performance of the louver is improved through lower cost.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a blade of a shutter. In addition, the present invention also relates to a shutter comprising the above blade. Background technique [0002] Louvres are widely used in construction to prevent rainwater from penetrating into interior spaces while maintaining ventilation. When installing louvers in ventilation and air conditioning systems, minimizing rainwater infiltration while reducing noise pollution also needs to be considered. Due to application requirements and space constraints, ventilation and airflow systems have very high airflow velocities, none of the existing louvers can meet the above requirements. [0003] Existing louvers, mainly using aerodynamically shaped blades to improve performance, require longer spans, resulting in increased manufacturing costs and installation space. At the same time, the ideal state of the gas flow in the boundary layer of the ga...
