Abstract

ventilador/difusor com admissão circular e saída de simetria não rotacional a presente invenção refere-se a um difusor (3) para um ventilador (2) em forma de construção axial radial ou diagonal, com uma abertura de entrada (10) e com uma abertura de saída (20) para um produto gasoso que flui desde a abertura da admissão (10) em uma direção de fluxo principal direcionado axialmente (s) de um compartimento interno do difusor (i) fechado por um alojamento externo (30), até a abertura de saída (20), sendo que a seção transversal (21) da abwertura de saída (20) é maior do que a seção transversal (11) da abertura de entrada (10) e a seção transversal do compartimento interno do difusor (i), partindo do corte (11) da abertura de entrada aumenta para o corte (21) da abertura de saída (20), sendo que o alojamento externo (30) forma um componente difusor externo (ad) que limita externamente o compartimento difusor interno (i), sendo que o alojamento externo (30) forma um componente difusor externo (ad) que limita o compartimento interno difusor (i) na parte externa. para conseguir de uma forma construtiva pouco complexa aprimoramentos do comportamento operacional relativo ao grau de ação e ruído e proposto que a seção transversal do componente difusor externo (ad) ao longo da direção de fluxo principal (s) converge de uma seção transversal (31) circular na abertura de entrada (10) para uma seção transversal (32) não circular na abertura de saída (20).
