FAN DIFFUSER HAVING A CIRCULAR INLET AND A ROTATIONALLY ASYMMETRICAL OUTLET. |
摘要 |
The invention relates to a diffuser (3) for a fan (2) of axial, radial, or diagonal construction, having an inlet opening (10) and an outlet opening (20) for a gaseous medium flowing through a diffuser interior (I) enclosed by an outer housing (30) in an axially directed main flow direction (S) from the inlet opening (10) to the outlet opening (20), wherein the cross section (21) of the outlet opening (20) is greater than the cross section (11) of the inlet opening (10) and the cross section of the diffuser interior (I) increases from the cross section (11) of the inlet opening to the cross section (21) of the outlet opening (20), wherein the outer housing (30) forms an outer diffuser part (AD) bounding the diffuser interior (I) on the outside. In order to achieve improvement of the operating behavior with respect to efficiency and noise, according to the invention the cross section of the outer diffuser part (AD) transitions along the main flow direction (S) from a circular cross section (31) at the inlet opening (10) to a non-circular cross section (32) at the outlet opening (20). |
