ABSTRACT:
A fan shroud for an outdoor unit of an air conditioner is positioned between an axial fan and a grill. The axial fan has multiple fan blades and is designed to pull air through a heat exchanger toward the grill. The fan shroud includes an inflow portion and an outflow portion diverging outwardly. The inflow portion has substantially an inwardly U-bent section for generating a primary vortex. The U-bent section has two generally parallel legs connected at one end to define a closed end further from the grill and disconnected at another end to define an open end closer to the grill. The U-bent section extends along the entire circumference of the inflow portion. The open end and the closed end of the U-bent section are positioned between a front edge and a rear edge of each fan blade.
