Abstract

Le présent modèle de l'invention concerne une porte à air d'un module de climatisation et un module de climatisation. La porte à air comprend une surface de paroi qui est utilisée pour guider le flux d'air et une pluralité de nervures saillantes qui sont prévues sur la surface de paroi et qui sont disposées dans une première direction, chaque deux nervures saillantes adjacentes définissant un canal sur la surface de paroi ; le canal permet au flux d'air de s'écouler ; les nervures en saillie s'étendent sur la surface de la paroi le long d'une seconde direction, et les nervures en saillie comprennent chacune une pluralité de saillies qui sont disposées séparément sur la surface de la paroi, et dans la même nervure en saillie, un espace étant défini par chaque deux saillies adjacentes sur la surface de la paroi ; et l'espace communique avec le canal. Du fait de l'espace communiquant avec le canal, lorsque le flux d'air dans le canal s'écoule vers l'espace, une partie du flux d'air s'écoule dans l'espace, et un tourbillon est généré dans l'espace, réduisant ainsi la vitesse d'écoulement du flux d'air, et réduisant ainsi le bruit généré par frottement entre le flux d'air et la surface de paroi de la porte à air. Par conséquent, la porte à air du module de climatisation prévue dans le présent modèle de l'invention présente l'avantage de générer un faible bruit. Le module de climatisation prévu dans le présent modèle de l'invention comprend la porte à air décrite.
