An air blower according to an embodiment of the present invention comprises: a support body through which a suction part is formed; a tower coupling part which is formed above the support body and in which a rotation module is installed; a dual discharge part which is coupled to the rotation module and includes a first discharge tower and a second discharge tower extending upward from the support body to be symmetrical to each other; and a control part which individually controls the rotation of the dual discharge part, wherein the control part can control the rotation angles of the first discharge tower and the second discharge tower so that air discharged from the first discharge tower and air from the second discharge tower is mixed, and the mixed air has an air volume larger than that of the air discharged from any one discharge tower among the first discharge tower and the second discharge tower.

The embodiments of the present disclosure provide a rotational electric fan including a fan head and a fan holder, wherein the fan head and the fan holder are connected through a rotational structure. The rotational structure includes: a fitting structure, including a circular cover fitting groove disposed on the fan head and a circular fitting head disposed on the fan holder and cooperating with the circular cover fitting groove, so as to fit the fan head and the fan holder together; a circular spacer, fixed on a surface of the circular fitting head facing toward the fan head and being in interference contact with a surface of the circular cover fitting groove facing toward the circular fitting head, so as to support rotational movement of the fan head relative to the fan holder.

A component carrier includes a baseboard, two sidewalls, and an ejector. The two sidewalls extend from opposite sides of the baseboard. The ejector includes a side plate, a handle, and a tab. The side plate is positioned in proximity to a first sidewall of the two sidewalls of the component carrier. The handle extends from a first end of the side plate in a first direction that is generally perpendicular to the side plate. The tab is positioned in proximity to the baseboard, and extends from a second opposing end of the side plate in a second direction that is generally perpendicular to the side plate and opposite to the first direction, the tab coupled to a first connector extending from the baseboard. The baseboard includes a first opening such that a portion of the tab of the ejector is configured to directly contact the electronic component therethrough.

A fluid heat exchanger with pump, adapted to drive a fluid for heat transfer, comprises a heat conduction unit, a diversion unit, and a housing unit. The heat conduction unit includes a heat conductor. The diversion unit includes a cover and a diversion plate. A cooling chamber is defined by the cover and the heat conductor. The cover is provided with a fluid stopper. The diversion plate is disposed in the cooling chamber, and one end of the diversion plate abuts against the fluid stopper, so that the cooling chamber is divided into an upper passage and a lower passage. The housing unit includes a housing and a pump module. The fluid in the housing is driven by the pump module to flow through the upper passage to the lower passage, and then the fluid returns to the housing to carry the heat from the heat conductor.

First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.

A fan includes a central hub defining an inlet, a motor positioned within the central hub, and an impeller positioned within the central hub. The impeller is operable to be rotated by the motor to generate air movement. The fan also includes a nozzle defining a channel that receives the airflow from the central hub. The nozzle also defines an outlet in communication with the channel to direct air out of the nozzle. The fan further includes a plurality of conduits connecting the nozzle to the central hub to direct air from the central hub to the channel and through the outlet of the nozzle. The nozzle defines a projection aligned with each conduit to divide air movement through the nozzle.

A blowing system includes: a first blowing unit including a first body that houses a first fan and includes a first air outlet for blowing-out wind from the first fan; a second blowing unit including a second body that houses a second fan, includes a second air outlet for blowing-out wind from the second fan, and has a shape that is in two-fold symmetry with the first body; and a first connection that rotatably-connects an edge on a back face-side of a first side face of the first body and an edge on a back face-side of a second side face of the second body so that an angle formed by the first and second bodies is variable. The first and second blowing units come into contact at three or more points, and the directions of respective rotation axes of the first and second fans cross at a predetermined angle.

A blower includes: a fan; a lower body having an inner space to receive the fan, and a suction hole; a first upper body communicating with the inner space and having a surface with a first discharge hole; a first damper movably coupled to the first upper body and penetrating the surface; the first damper having a first end facing an outside of the first upper body and a second end opposite to the first end; and a first bar extending along and coupled to the second end of the first damper.

Disclosed is a covering of a fan unit of an information handling system. The covering contains a bottom covering and a top covering. The bottom covering contains i) copper and an first aluminum alloy, or ii) 10 wt. % to 50 wt. % of a thermally conductive plastic, and 50 wt. % to 90 wt. % of a post-consumer-recycled (PCR) plastic and/or biodegradable plastic. The top covering contains copper and a second aluminum alloy. The bottom covering houses a motor and blades of a fan of the fan unit, the top covering abuts against the bottom covering, and the fan is positioned in a space formed between the bottom and top covering. Fan unit containing the covering, and an information handling system containing the fan unit is also disclosed.

A centrifugal fan assembly including fan wheel, a primary inlet bell, a secondary inlet bell, and a flow grid. The primary inlet bell and secondary inlet bell direct air into an inlet of the fan wheel of the centrifugal fan. Also disclosed is a sound reduction assembly for reducing the sound produced by a centrifugal fan or centrifugal compressor. A method of directing air flowing into a centrifugal fan or a centrifugal compressor is also disclosed.
