An assembly including a wearable blower having a fan, a motor, an air duct having a duct housing thereof, a handle attached to the duct housing, and a hanger disposed on the duct housing. The hanger has an attachment part attached to the duct housing and adjacent to the handle and a hanger part connected to the attachment part for holding an accessory attached to the blower. The hanger part rotates with respect to the duct housing at a first hanging position whereat the hanger part is unfolded with an opening mouth for holding the accessory of the blower and the hanger part rotates with respect to the duct housing at a second folded position. Thus, the arrangement of the hanger can help the user to hold the accessory of the blower at the work states.

An apparatus includes a pipeline-transport compressor configured to receive, in use, a product stream from a pipeline. The cooler unit is configured to receive, in use, a cooler air intake from the pipeline-transport compressor. This is done in such a way that removal of the cooler air intake by the cooler unit, in use, moves the cool air across the cooler bundles and out through the cooler unit, and cools the pipeline-transport compressor. An air exhaust power generation unit is configured to generate, in use, electric power in response to the cooler unit, in use, urging, at least in part, the cooler air intake toward, at least in part, the air exhaust power generation unit.

A fan wheel with a hub is centrally supported with respect to a drive and coaxially rotatable with the hub between stops relative to the hub. The fan wheel having fan blades extending radially from the hub are rotatable about their axes in a range delimited by the stops. Overlaying the rotational support between the stops of the hub, a rotational support between the hub and the drive is provided including a planetary drive in operative arrangement with an adjustment control ring of the driven hub. The fan blades are rotatable in the hub about their blade axes, and adjustment of the blade angles of the fan blades via drive connections to the adjustment control ring, which connections operate in a manner superimposed on one another starting from the drive of the fan wheel.

A fan blade (1) has a front inflow edge (2) and a rear outflow edge (3). The fan blade (1) has an at least partially wavy inflow edge (4). The wavy inflow edge (4) forms a wave (W) with a specific three-dimensional waveform.

A motor comprising a casing, rotating shaft, magnetic ring, three-phase hollow cup coil winding and insulation end cover, is provided. The casing includes a sleeve and inner core arranged coaxially with the sleeve and air guide plates connected to the sleeve and inner core, the sleeve, inner core and two adjacent air guide plates are surrounded to form an air guide channel, the inner core is provided with a mounting hole, the bearing is installed in the mounting hole, and a rotating shaft passes through the bearing, a magnetic ring is sleeved outside one end of the rotating shaft, the three-phase hollow cup coil winding is sleeved outside the magnetic ring. A rotating gap is set between the three-phase hollow cup coil winding and the magnetic ring, and insulating end cover is installed on the outlet of the sleeve. A wind end fixes the three-phase hollow cup coil winding in the sleeve, and the inner core is provided with heat dissipation holes that are all connected with installation holes.

A cooling fan and an electronic device are provided. The cooling fan comprises a plurality of blades disposed in a circumferential direction of a rotating shaft. The plurality of blades includes a first blade and a second blade. A windward surface of the first blade includes a first alignment part and a first offset part. The first alignment part is aligned with a windward surface of the second blade, and the first offset part and the windward surface of the second blade are arranged in a staggered manner.

A turbofan engine includes a propulsor section that has a propulsor shaft in driving engagement with a propulsor. An epicyclic gear system has a gear mesh lateral stiffness and a gear mesh transverse stiffness. A gear system input defines a gear system input lateral stiffness and a gear system input transverse stiffness. The gear system input lateral stiffness is less than 5% of the gear mesh lateral stiffness. A first turbine section rotates at a first speed, and a second turbine rotates at a second speed that is faster than the first speed. A first performance quantity is defined as the product of the first speed squared and the first area of the first turbine, a second performance quantity is defined as the product of the second speed squared and the second area of the second turbine, and a performance quantity ratio is between 0.5 and 1.5.

A handheld fan includes a housing, a fan assembly mounted in the housing and close to a rear portion of the housing, a semiconductor chilling plate mounted in the housing and arranged in front of the fan assembly, and a cold conducting piece arranged on a front end of the housing. A front end surface of the semiconductor chilling plate is a cooling surface. The cold conducting piece is attached to the front end surface of the semiconductor chilling plate. An air outlet is defined between the cold conducting piece and the housing.

An air moving device includes a housing member, an impeller assembly, and a nozzle assembly. The nozzle assembly can include one or more angled vanes set an angle with respect to a central axis of the air moving device. The air moving device can output a column of moving air having an oblong and/or rectangular cross-section. A dispersion pattern of the column of moving air upon the floor of an enclosure in which the air moving device is installed can have an oblong and/or rectangular shape. The dimensions of the dispersion pattern may be varied by moving the air moving device toward or away from the floor, and/or by changing the angles of the stator vanes within the nozzle assembly.

A fan assembly and an inverter are provided. The fan assembly includes a fan guard, a fan body and a noise reduction mounting member. The fan body directly faces an air inlet, the air inlet is covered by a fan guard, and the noise reduction mounting member is arranged on the fan body, to provide a preset distance between the fan body and the fan guard, and the noise reduction mounting member is configured to mount the fan body on a to-be-mounted component in a buffered manner. The distance between the fan body and the fan guard can reach the preset distance due to the noise reduction mounting member. In addition, the noise reduction mounting member plays a vibration isolation function between the fan body and the to-be-mounted component, which improves the sound quality.
