Abstract
A housing for an axial flow heat-dissipating fan includes an annular wall including an air inlet in a first end thereof and an air outlet in a second end thereof. A motor of an axial flow heat-dissipating fan is received in the annular wall. A plurality of axially extending slits are defined in a circumference of the annular wall. Each axially extending slit has a first end adjacent to the air outlet and a second end adjacent to the air inlet. A width of the first end of each axially extending slit is smaller than that of the second end of each axially extending slit.
