Abstract
Abstract A mounting arrangement for an axial fan, wherein the axial fan is used for moving air through a cabinet or enclosure for heat generating electrical components. The axial fan is housed in a cylindrical housing having a flange and air inlet at one end and a flange and air outlet at the other end. The mounting arrangement also includes a support having a base with an air opening and two parallel walls. The parallel walls including catches for attaching the housing to the support. The support is mounted in an enclosure or formed as an integral part of the enclosure.
