An equipment chassis includes a rear-mountable fan tray assembly (FTA) having a plurality of fans arranged into two or more FTA housing portions, the rear-mountable fan tray assembly being slidably insertable into and retractable from the equipment chassis for facilitating front-to-back airflow while providing ease of access. The FTA housing portions are articulatably coupled to each other and are arranged to follow a smooth motion path when traveling from a horizontal position to a vertical position and vice versa when the rear-mountable fan tray assembly is either inserted into or retracted from the equipment chassis, wherein a top FTA housing portion is guided by a top curvilinear tracking path and a bottom FTA housing portion is guided by a bottom curvilinear tracking path.

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.

A cooling device includes a fan; an intake-side intrusion-preventing member that is provided on an intake side of the fan and prevents an object from entering the fan; an exhaust-side intrusion-preventing member that is provided on an exhaust side of the fan and prevents an object from entering the fan. The intake-side intrusion-preventing member and the exhaust-side intrusion-preventing member have different shapes.

A shelf apparatus includes a body that includes a first opening provided in a top surface, a second opening provided in a bottom surface, and a back plane that includes a first and a second terminals; a first air-cooling device that is attachable to the top surface and includes a first substrate, a first fan, and a first connector configured to couple the first substrate to the back plane, wherein the first terminal is coupled to the first connector inserted into the first opening; a second air-cooling device that is attachable to the bottom surface and includes a second substrate, a second fan, and a second connector configured to couple the second substrate to the back plane, wherein the second terminal is coupled to the second connector inserted into the second opening; and an air guide device that is attachable to a bottom surface of the second air-cooling device.

Power entry and distribution for network communication systems are disclosed. For certain embodiments depicted, a power distribution board with an open-grid configuration receives power feed/return lines from a power entry connector and distributes the power feed/return lines for a network processing system. The open-grid configuration facilitates airflow through a chassis and thereby provides improved cooling. Further, a modular power entry connector can be used to facilitate connection of power feed/return cables to the chassis for the network processing systems while improving safety for high power implementations.

The heat dissipation cabinet includes a cabinet body, a cabinet door, and a baffle. The cabinet body includes a top wall and a bottom wall that are oppositely disposed, and a side wall connected between the top wall and the bottom wall. The cabinet door is installed at a position of the side wall in the cabinet body, and an air outlet passage is disposed in the cabinet body that is close to a position of the top wall. An air inlet component and an air outlet component are disposed in the cabinet door, and the air outlet component is located between the air inlet component and the top wall, and is located at one end of the air outlet passage. An electronic apparatus placement area is disposed in the cabinet body, and the baffle is disposed between the electronic apparatus placement area and the cabinet door.

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.

A device for use with a fan. The device includes a shaft mounted at opposite ends via brackets to a housing of the fan, a curtain for blocking airflow through the fan in a closed position, the curtain being wound onto the shaft in an open position, a closing mechanism for unwinding the curtain to the closed position, and a locking mechanism for locking the curtain in the open position. In response to detection of malfunction of the fan the locking mechanism is released and the closing mechanism unwinds the curtain to the closed position.

An information handling system includes a front door having a first frame, a main portion, and a rear portion. The main portion includes a second frame, a component node having multiple components, and a first channel. The rear portion includes a third frame, a cooling coil, a cooling fan, and a second channel. The information handling system is airtight when the first frame is in physical communication with a first end of the second frame and the third frame is in physical communication with a second end of the second frame. An airflow circulates within the information handling system to cool the components in the component node. The airflow circulates from the cooling coil to the cooling fan, through the second channel, through the first channel, through the component node, and back through the cooling coil.
