摘要： A misting fan includes a nozzle, a fan assembly, and a support assembly. The nozzle is configured to spray water. The support assembly is formed with a coupling portion for detachably coupling a battery pack. The nozzle is disposed on the fan assembly or the support assembly and includes a nozzle body and a second part. The nozzle body includes a first part formed with a first surface and the second part is detachably installed to the nozzle body and formed with a second surface. When the second part is installed to the nozzle body, a water flow channel is formed between the second surface and the first surface. When the second part is detached from the nozzle body, the first surface is at least partially exposed for cleaning access.

摘要： A fixed blade has a chord line inclined downstream in a rotation direction of a rotor vane throughout a radial direction. An average of an installation angle on an outer peripheral side of the fixed blade from a midpoint of a straight line extending in the radial direction from an outer peripheral end of an upstream edge of the fixed blade to an outer peripheral surface of the fixed hub is less than an average of the installation angle on an inner peripheral side of the fixed blade from the midpoint of the straight line, where the installation angle is formed by the chord line of the fixed blade with respect to a plane perpendicular to an axis.

摘要： A network-controllable cooling fan can have a recessed connector port with an internal tongue that defines an edge connector having a plurality of electrical contacts. The tongue can also define a plurality of electrically conductive tracks that electrically couple with the electrical contacts. Control logic can have a plurality of electrical connections and a logic bus that electrically couples the electrical connections of the control logic with the electrically conductive tracks defined by the tongue. An electrical biscuit-connector with internal electrical interconnections can join the network-controllable cooling fan with another network-controllable cooling fan, extending the logic bus while obscuring the electrical interconnections from a user's view.
