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.

System for selectively contacting a cleaning composition with a surface of a turbine engine component is presented. The system includes a cleaning apparatus and a manifold assembly. The cleaning apparatus includes an upper portion and a lower portion defining a cleaning chamber configured to allow selective contact between the cleaning composition and a surface of the first portion of the turbine engine component. The upper portion includes a plurality of fill holes in fluid communication with the cleaning chamber, and the lower portion includes a plurality of drain holes in fluid communication with the cleaning chamber. The manifold assembly is configured to selectively circulate the cleaning composition from a reservoir to the cleaning chamber via the plurality of fill holes, and recirculate the cleaning composition from the cleaning chamber to the reservoir via the plurality of drain holes. Methods for selectively cleaning a turbine engine component is also presented.

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.

The invention relates to a separating device for a turbomachine, comprising at least one housing (12) that has at least one bearing receiving area (24), which defines at least one bearing axis (26), and at least one wheel-side area (28). The separating device also comprises at least one swirling unit (32), which is arranged on the housing (12) in particular, for deflecting and/or swirling at least one fluid and/or particle flow (34), wherein the swirling unit (32) has at least one flow recess (38) which is delimited by a wall (36) of the housing (12) and which extends within the wheel-side area (28) at a distance from the bearing axis (26). According to the invention, the swirling unit (32) comprises at least one seal gap element (40) which is arranged on a wall (36) of the housing (12) and which is designed to deflect and/or swirl at least one fluid and/or particle flow (34) flowing through the flow recess (38) along the bearing axis (26) and/or towards the bearing axis (26).

A non-clogging pump includes a pump casing and an impeller that includes a main plate portion and a vane portion, in which the main plate portion includes a main plate protrusion portion that protrudes in a counter-inflow direction, the vane portion includes a first end face and a second end face and is connected to the main plate protrusion portion at an inner periphery-side end portion, and an inner peripheral wall that forms the suction port of the pump casing includes a suction port protrusion portion that is provided at a portion in a rotation direction of the rotating shaft, is disposed along the second end face with a gap from the second end face, and protrudes toward a center side of the suction port.

A vacuum cleaner assembly configured to be mounted in a vehicle. The vacuum cleaner assembly including a vacuum unit configured to draw a vacuum, a canister assembly configured to collect debris and coupled to the vacuum unit, a hose junction configured to serve as a pathway for debris, and a chassis connecting the hose junction to the canister assembly. A pathway through the vacuum cleaner assembly may turn 180 degrees in the hose junction. A dirty air port of the canister assembly may be disposed at an angle relative to a surface of the chassis to facilitate placement and removal of the canister assembly.

The device includes a substantially cylindrical, oblong, rigid, extension pole having a distal end upon which is formed an articulatable jaw structure head which can be actuated between open and closed positions by the pull of either a medial handle or knob located at the proximal end. A collector sock made from a pliable sheet material can be mounted upon the jaw structure so that the sock enwraps the entire item to be dusted such as a ceiling fan blade. The inner surface of the sock surrounding its open end maw can include asperities and electrostatic, dust adhering fibers to help scrape off and capture fine particles of dust and other debris from the item being dusted. The head can include a pair of parallely separatable cantelevered beams engaging the sock.
