초록 ▼

A direct drive cooling fan employs a specially configured, X-shaped mounting chassis to securely mount the drive motor. The preferred fan comprises a parallelepiped housing protectively enclosing an internal subframe securing a drive motor and a propeller. A reinforcing edge circumscribes the housing front and rear to facilitate guard coupling. The subframe comprises two parallel elongated brackets, each formed of channel material. Each strut comprises several regularly spaced apart follower slots to which the X-shaped mounting chassis is mounted. The preferred mounting chassis comprises a pair of complimentary brackets welded to opposite sides the drive motor shell. The brackets comprise a curved, interior cradle that flushly mates with the circumferential periphery of the drive motor. The brackets have wings at either end of the cradle terminating in tabs laying parallel with the subframe brackets. An attachment hole on each tab allows for the attachment of the mounting chassis to the subframe brackets. This attachment creates increased internal strength and allows for the torsional forces generated by the drive fan to be dissipated evenly throughout the fan housing. The diametrically aligned cradle wings form an X-shaped profile with the motor at the center.
