A magnetically attracted fan set comprises N+1 fans, the N≥1, and each of the N+1 fans has a fan frame and an airflow generating component disposed on the fan frame. Any two adjacent fans of the N+1 fans respectively have a joint surface, each of the joint surfaces has at least one fixing member capable of forming magnetic attraction, when the joint surface is close to the other joint surface at a distance sufficient for the two fixing members on the two joint surfaces to form magnetic attraction, two of the N+1 fans are joined together. Accordingly, the invention is capable of directly and quickly joining the N+1 fans without requiring complicated assembly gestures or other external components.

A ceiling fan with a ceiling projection function includes a ceiling fan body and a ceiling fan housing. The ceiling fan body includes a plurality of blades, a motor that drives the blades to rotate, and a hanging rod. The ceiling fan housing is provided with a pattern hole unit and a light-emitting unit. The pattern hole unit has at least one pattern hole. The pattern hole of the pattern hole unit passes through the ceiling fan housing. The light-emitting unit has at least one light-emitting member. When in use, the light-emitting member of the light-emitting unit projects a light beam passing through the pattern hole of the pattern hole unit to project a pattern of the pattern hole of the pattern hole unit outside the ceiling fan housing and above the blades.

Turbine engine assembly comprising: an external casing (28) of a low-pressure compressor (4), an annular wall (30) and an oil tank (46) with a circular chamber (48) around an axis (14) of the compressor. The wall (30) comprises an inner surface (38) delimiting an primary guide path for the flow of the compressor, and an external surface (40) radially opposite the inner surface and delimiting the internal chamber (48) of the tank (46).

A temperature destratification assembly can include an outer housing. An impeller can be positioned within the outer housing between the inlet and outlet of the outer housing. The impeller can have an impeller hub and a plurality of impeller blades extending radially outward from the impeller hub. The assembly can include an impeller motor configured to rotate the impeller blades about an axis of rotation. A stator can be positioned within the outer housing between the impeller and the outlet of the outer housing. The stator can include a plurality of vanes. The stator vanes can include an upstream edge at the upstream end of the stator, a first surface extending from the upstream edge to the downstream edge of the vane, and a second surface opposite the first surface and extending from the upstream edge to the downstream edge of vane. A plurality of the vanes can have a downstream edge at the outlet of the outer housing.

A fan carrier is to be placed in physical communication with a fan-side connector of an information handling system. The fan carrier includes a plunger assembly and multiple isolators. The plunger assembly is biased toward an at-rest position. The plunger assembly is in physical communication with the fan-side connector when the plunger assembly is in a deformed position. The isolators are mounted on the fan carrier, and dampen vibration energy in the fan carrier and prevent the vibration energy from being transferred to the fan-side connector. The isolators enable the fan-side connector to float within the fan carrier.

A waterproof fan according to an embodiment of the present invention includes: a blade module configured to be operated by a motor; and a frame having an accommodation hole that accommodates the blade module, the frame being formed to surround the accommodation hole, and the frame includes an opening that opens a part of the accommodation hole.

A waterproof fan includes: a rotor including a rotating blade capable of rotating about a rotation axis; a stator including a plurality of stator cores extending in a radial direction relative to the rotation axis, and a winding wound around each of the stator cores; a frame including a housing space opening toward one side of the rotation axis; a circuit board electrically connected to the winding and housed in the housing space; a waterproofing resin portion covering the stator and the circuit board to block the opening of the housing space; and a positioning member provided in the housing space and configured to position the circuit board at a position away from an inner wall of the housing space.

Provided is a reversible fan including: a fin configured to produce a current of air in both of a normal direction and a reverse direction; an impeller configured to be rotatable about a rotation axis; a motor configured to rotate the impeller; and a tubular frame housing the impeller and the motor, wherein the fin has a shape that allows producing louder noise upon producing the current of air in the normal direction than upon producing the current of air in the reverse direction, and protrudes inward in a radial direction from an inner peripheral surface of the frame.

An un-ducted turbofan engine defining a radial direction and an axial direction that includes a core engine, a fan, a plurality of variable outlet guide vanes, and a pitch change mechanism. Each of the plurality of variable outlet guide vanes are attached in a rotatable manner to the core engine of the un-ducted turbofan engine. The pitch change mechanism is positioned radially between the engine air flowpath and the plurality of variable outlet guide vanes and coupled to at least one variable outlet guide vane of the plurality of variable outlet guide vanes for changing a pitch of the at least one variable outlet guide vane.

A clip-on fan includes a specialized clamping clip that is attached to rectangular or cylindrical tent poles that are commonly used for grow tents; wherein fans are essential components for growing in tents and the current designs clip-on fans do not meet the needs of indoor growers; the clip-on fan comprising a fan assemblage and clip clasp assemblage arranged at the base of the complete product, wherein the clip is able to grasp to the vertical tubular structure of a grow tent; the grasping clasp assembly consisting of: a left clip plate, a right clip plate, a clip plate rotation shaft, a clip spring, a fan connection hole and, a clip clamp opening; the left and right clip plates are connected in a bilateral symmetry through the clip plate rotation shaft at the central connection position.
