Abstract: The present disclosure generally relates to a mounting device for mounting a fan unit. The mounting device may include a reference plane and a reference axis normal to the reference plane, the fan unit in a disengaged orientation being receivable towards the reference plane along the reference axis. The device may also include a set of engagement members radially disposed around the reference axis and arranged to surround the fan unit in the disengaged orientation at the reference plane, the engagement members engageable with the fan unit upon actuation of the fan unit planarly along the reference plane from the disengaged orientation to an engaged orientation. The dice may also include a set of engagement elements disposed on the engagement members, the engagement elements engageable with a set of mounting holes of the fan unit upon actuation of the fan unit to the engaged orientation.
