In one embodiment, a modular electronic system includes a front panel comprising openings for receiving a plurality of modules, a removable fan tray comprising a plurality of fans for cooling one or more of the modules with airflow entering the modular electronic system at the front panel when the plurality of fans are operating, and a fan tray channel for receiving the fan tray and positioning the fans in a row generally parallel to the front panel. The channel extends from one of the openings in the front panel and is contained within a horizontal plane in the modular electronic system.

A subrack assembly can be configured for use with a subrack that includes an installation space for electronic circuit boards, an air distribution duct, an air collecting duct, and a slot. A fan tray can be configured to be slidably and removably received in the slot and can include panel and support one or more electric fans. The panel of the fan tray can at least partly define a first air chamber within the fan tray, and, in cooperation with the subrack, can define a second air chamber within the subrack, with the panel separating the second air chamber from the first air chamber. The one or more electric fans can be configured to drive an air flow through the first and second air chambers, the air collecting duct, and the air distribution duct, to cool the electronic circuit boards within the installation space.

A fan assembly includes a fan module having a plurality of mounting openings, a housing partially surrounding the fan module, and a plurality of dampers that extend through the plurality of mounting openings to couple the fan module to the housing.

A modular fan assembly for use in a multi-device storage enclosure. In some embodiments, the fan assembly has a rigid open frame with opposing first and second ends. A first fan is connected to the first end and a second fan is connected to the second end. The first and second fans are configured to establish a fluidic airflow through the frame. An airflow diverter positioned in an intermediate portion of the frame between the first and second ends divert at least a portion of the fluidic airflow through a first aperture of the frame to cool an active element outside the frame.

The inventive subject matter discloses a handle, a pluggable module, and an electronic apparatus. The electronic apparatus includes a frame body and a plurality of pluggable modules. Each of the pluggable modules includes a rack and a handle, wherein the rack is adapted to receive an electronic module. The handle includes two elastic arms and a force-bearing arm, wherein each of the two elastic arms includes a hook section, and the two hook sections are adapted to be engaged with positioning structures of the frame body respectively. The force-bearing arm is connected between the two elastic arms, and the two elastic arms shift toward each other to enable the two hook sections to be detached from the positioning structures when a force is applied to the force-bearing arm. With the aforementioned design, the pluggable module could be instinctively inserted into or removed from the electronic apparatus.

A shutter unit includes a plurality of shutters that are grouped into groups corresponding to one of a plurality of fans, the grouped shutters being arranged beside one another and positioned on a leeward side or a windward side of the corresponding one of the plurality of fans, the grouped shutters being capable of pivoting between an open position and a closed position, the plurality of fans being for sending wind to an inside of an electronic apparatus casing; a coupling member that couples the grouped shutters together so that the grouped shutters are pivotable; and a retaining member that retains the grouped shutters in a state of being in the open position and inclined with respect to a flow direction of returning wind returning from the inside of the electronic apparatus casing toward a side of the plurality of fans.

Methods, systems, and apparatus, including a housing defining a top surface, a bottom surface, and first and second side surfaces. Also included is a first rail extending from the first side surface and a second rail extending from the second surface such that when the first and second rails are slidably engaged with a third surface. A blower device is included that is axially disposed between the top and bottom surface, wherein a first end of the housing defines a first plenum outlet, the top surface defines a plenum inlet, the bottom surface defines a second plenum outlet that is positioned on a second side of the blower device and that fluidly couples the first plenum chamber to the second plenum chamber. Further, the second plenum chamber is formed by the first and second rails, the bottom surface and the third surface has a third plenum outlet.

Apparatuses and methods are provided for protectively covering an air inlet or outlet of an air-moving assembly. The apparatus includes a protective cover assembly, which includes a retractable cover and a spring-biasing mechanism. The retractable cover transitions between a retracted state, when the air-moving assembly is operatively positioned within the chassis, and in extended state, when the air-moving assembly is withdrawn from the chassis. In retracted state, the retractable cover is retracted away from the air inlet or outlet, and in extended state, the retractable cover covers, at least partially, the air inlet or outlet. The spring-biasing mechanism is coupled to the retractable cover and biases the retractable cover in the extended state when the air-moving assembly is withdrawn from the chassis, and compresses to allow transition of the retractable cover to the retracted state as the air-moving assembly is inserted into operative position within the chassis.
