Systems and methods for controlling airflow through a casing or shelf assembly are provided. An apparatus, according to one implementation, includes a mount plate configured to be attached to a side panel of a casing for housing network equipment. For example, the mount plate may include a window. The apparatus also includes one or more hinges arranged at an edge of the window of the mount plate and a baffle pivotably attached to the one or more hinges. The baffle can be arranged within a range of positions with respect to the mount plate to control an amount of airflow through the window. Within these range of positions, the baffle is configured to redirect the airflow in a front-to-back direction through the casing.

A converter includes a housing having a first interior and a second interior. The first interior is arranged separately from the second interior. Part of the first interior protrudes into the second interior and forms a heat-exchanger duct. A gaseous heat flow circuit is established within the first interior and flows in through an inlet opening of the heat-exchanger duct and flows out through an outlet opening of the heat-exchanger duct. The second interior forms a cooling duct. A gaseous cooling flow flowing through the cooling duct is established and flows around the heat-exchanger duct. The cooling duct is arranged in a region of overlap with the heat-exchanger duct in such a way that a first flow direction of the gaseous heat flow circuit runs substantially perpendicularly or parallel to a second flow direction of the gaseous cooling flow.

A fan assembly includes a socket to receive a fan module, a fan flap coupled to a first side wall of the socket, and an anti-reflow device coupled to a second side wall of the socket. The fan flap moves in a curved path between a first position and a second position. The anti-reflow device has an attachment feature, an embossed feature, and a stopping feature. The attachment feature attaches the anti-reflow device to the second side wall. The embossed feature extends through a first aperture in the second side wall. The stopping feature extends through a second aperture in the second side wall and contacts the fan flap. When the fan module is removed, the stopping feature retains the fan flap in the first position to block the socket and prevent air from reflowing through the socket.

An actuating breathable material structure is disclosed and includes a supporting main body, a plurality of actuating breathable units and a plurality of micro processing chips. The supporting main body is made of a supporting matrix. The plurality of actuating breathable units and the plurality of micro processing chips are compounded and are integrally formed with the supporting matrix into one piece. By controlling the actuation of the plurality of actuating breathable units through the plurality of micro processing chips, a breathing effect resulting from gas transportation in a specific direction is performed.

Several transportable datacenters are described. The transportable datacenters include transport systems allowing them to be transported between an assembly location and an operating location. The transportable datacenters also include a ventilation system for cooling processors positioned in racks in the datacenters. The ventilation system draws cold air from the environment, through processor bays containing the processors and then exhausts the air back to the environment.

The invention provides a sounding device. The sounding device comprises a housing body with an accommodating space, a one-way inlet valve and a one-way outlet valve. A speaker unit partitions the accommodating space into a front cavity and a back cavity. The one-way inlet valve communicates the outside and the back cavity and is used for introducing air into the back cavity. The one-way outlet valve communicates the back cavity and the outside and is used for discharging the air in the back cavity outside. A first through hole communicating the outside and the back cavity is formed in the housing body. The invention also provides a mobile terminal. Compared with the related art, the sounding device and the mobile terminal of the invention have better reliability and better performance.

The disclosure provides a network equipment power supply and a heat dissipation system therefor. The heat dissipation system includes a liquid-cooling heat dissipation device and an air-cooling heat dissipation device. The liquid-cooling heat dissipation device includes a liquid inlet, a liquid outlet, and a liquid-cooling pipe between them, wherein liquid-cooling medium flows inside the liquid-cooling pipe and takes away heat generated by components arranged around the liquid-cooling pipe; The air-cooling heat dissipation device includes an air inlet, an air outlet, and an air-cooling channel between them, wherein airflow passes through the air-cooling channel and takes away heat generated by components arranged around the air-cooling channel. The disclosure conducts hybrid heat dissipation combining characteristics of liquid-cooling heat dissipation and air-cooling heat dissipation to effectively enhance heat dissipation efficiency, and provides a new choice for design of a power supply unit with high power density.

A heat exchanger package for a dry-type transformer is provided. The heat exchanger package includes a package housing including an air inlet and an air outlet and adapted to fix to the dry-type transformer; and a first heat exchanger located in the package housing and between the air inlet and the air outlet, the first heat exchanger arranged at a first angle of inclination with respect to a first inner surface of the package housing.

An electronic device includes a substrate which is provided in a housing and on which a heat generating member is mounted, a cooling member configured to cool the heat generating member, a first tube including one end connected to the cooling member and configured to supply a cooling medium to the cooling member or discharge the cooling medium from the cooling member, a joint member including a first connection portion extending in a tube axial direction of the first tube and connected to another end of the first tube, a support member fixed to the housing or the substrate, and a tube fixing portion configured to fix the first tube to the support member.

Cooling systems of one or more electronic racks in a cluster or point of deliver (PoD) are disclosed. A data center system includes an array of electronic racks. Each electronic rack contains a number of server chassis. The system further includes a number of rear cooling doors respectively connected to the electronic racks. Each rear cooling door cools warm/hot air exhaust from a corresponding electronic rack. The system further includes a number of airflow distributors. Each airflow distributor attaches to a side of an electronic rack to supply and distribute a cool/cold airflow to the electronic rack. The distributor either assembled in the PoD or pre-attached with the racks. The system further includes a containment to direct the cooled air towards the airflow distributors.
