An air-cooling mechanism. An electric fan has a fan motor and fan blades. A front grill covers the fan blades. A removably attached ice pack holder holds an ice pack. The ice pack holder has an ice pack holder grill and attachment brackets. The ice pack holder also includes a holding mechanism for receiving and holding the ice pack. Connection straps are used to connect the attachment brackets to the electric fan's front grill. In a preferred embodiment the connection straps are Velcro® straps. In a preferred embodiment, the ice pack includes ice pack holes for allowing air flow.

The present disclosure relates to a portable air purifier and the fan module provided therin. In the disclosed invention, the portable air purifier includes a fan module that is disposed between a discharge surface and a filter, and suctions air having passed through the filter, in an axial direction, and discharges the air in a direction between the axial direction and a radial direction.

The disclosure relates to an asymmetrical double-outlet blower, including an upper case, a lower case and an impeller. The upper case includes an inlet. The lower case and the upper case are assembled to form a housing having an accommodation space, and form a first outlet and a second outlet. The accommodation space is in fluid communication with the first outlet, the second outlet and the inlet. The first outlet and the second outlet are disposed on a lateral periphery of the housing and face two opposite directions, respectively. An opening cross-sectional area of the first outlet is less than an opening cross-sectional area of the second outlet. The impeller is accommodated within the accommodation space of the housing, spatially corresponding to the inlet, and rotated around a rotation axis. An airflow is inhaled through the inlet and transported to the first outlet and the second outlet, respectively.

Airflow from a blower fan can be adjusted between a cooling air mode where cooling air flows freely to the ambient surroundings and a noise mode where the airflow is partially or fully restricted in order to produce different levels of soothing background noise. The airflow from the fan can be split or divided between varying degrees and combinations of unrestricted airflow, partially restricted airflow and fully restricted airflow to produce a wide range of cooling airflows into the ambient with or without the production of additional background noise. A perforated drum surrounds the fan to form a chamber within which airflow can resonate at various frequencies and amplify noise levels selected by rotating the drum around the fan.

An electric motor includes a fan guard and rotor shaft mounted rotatably relative to the fan guard and angle sensor. A housing of the angle sensor is connected to a torque support, which is connected to the fan guard, the torque support having members having a meandering shape.

The present application discloses a flow guide cover and a server having the same. The flow guide cover includes an annular frame, a flow directing member, an air collecting ring, a plurality of first air guide vanes and a plurality of second air guide vanes. The flow directing member is arranged inside the annular frame and comprises a first surface and a second surface which are arranged opposite to each other, the first surface having an area greater than that of the second surface. The air collecting ring is arranged surrounding an outer periphery of the flow directing member, located between the flow directing member and the annular frame, and spaced apart from the flow directing member and the annular frame respectively. When the flow guide cover of the present application is used in conjunction with a fan, heat can be dissipated more evenly.

There is provided a radiator fan configured to introduce outside air into a radiator in front of an engine. The radiator fan includes: a propeller disposed behind the radiator; a fan motor configured to drive the propeller to rotate; and a fan shroud covering the propeller from behind. The fan shroud is formed with a plurality of hoods whose exhaust air ports are directed in any directions in a range from a lateral direction to a downward direction.

A humidification and air cleaning apparatus is provided that may include a water tank having a discharge port which is open toward an upper side, and a discharge grill disposed at the water tank and covering the discharge port. The discharge grill may have a plurality of vanes disposed at the discharge port and spaced apart from each other, and when viewed from a top, overlap each other to cover the discharge port. An edge of a vane may overlap an edge of an adjacent vane, thereby minimizing scattering of droplets to an indoor space while minimizing resistance of discharged air.

Embodiments disclosed herein may provide an air conditioner having a case and a cover coupled to the case. A cover separation unit may separate the cover from the case at upper and lower sides. The cover separation unit may include a lever that slides along an outer surface of the case and a pusher rotatably coupled to the lever to rotate to push the cover. A guide may guide the pusher to rotate as the pusher is moved along an outer surface of the case.

A motor assembly having a rotational axis includes a motor housing comprising a plurality of cooling openings extending therethrough and defining a chamber. The motor assembly also includes a stator fixedly coupled to the motor housing and positioned within the chamber. A rotor is coupled to at least one of the motor housing and the stator, wherein the rotor is configured to rotate about the axis and is positioned within the chamber. The motor assembly includes a fan having a first inlet side on a first axial side of the fan and a second inlet side on a second, opposing, axial side of the fan. The fan is configured to draw cooling air in a first direction through the at least one cooling opening into the first inlet side, and the fan is also configured to draw cooling air in a second, opposite direction into the second inlet side.
