A ventilation unit for an electrical cabinet, comprising a fan, a casing that comprises a plinth and a cover assembled on the plinth, wherein: the casing has a straight slab form having a square base, four lateral faces and an upper face; and the plinth comprises a lower wall forming the base of the casing and a lateral wall following the four lateral faces of the casing, an opening made through the lower wall thereof and a seat made around the opening thereof and receiving the fan, and wherein following each lateral face, the lateral wall of the plinth comprises a first grid and the ventilation unit comprises a second grid mounted pivotably and covering the first grid.

An apparatus for dynamic thermal control is provided. The apparatus includes a fan module with multiple fan units, a deflection member configured to direct airflow received from the fan module, and a system component. The apparatus also includes a chassis management controller (CMC). The CMC is coupled to the fan module, deflection member, and the system component. The CMC is configured to dynamically control the deflection member to direct airflow from the fan module to the system component by accounting for at least one environmental element within the apparatus.

A modular cable backplane assembly for high-speed interconnection of digital electrical components in Field Replaceable Units, FRUs, (12) mounted in an equipment rack (10). A vertical stack of a plurality of parallel horizontal cable connector carrying trays (51) is mounted within a rigid chassis (32). The trays provide electrical component connector pins on a front side and high-speed data and power cable connectors on a back side thereof. At least one enclosed vertical channel (21) is attached to the vertical stack of horizontal plates (51) for protectively routing cables to the cable connector carrying trays. Vertical spacing of the cable connector carrying trays enables cooling fans (41) mounted on the rigid chassis to provide unimpeded front-to-back airflow over the FRUs (12). The cable backplane assembly may be removed and replaced as a unit, and may be upgraded, in situ, from copper to optical connections.

The application relates to an electrical apparatus such as an inverter or other electrical apparatus. The apparatus includes a cabinet having multiple cabinet sections, each cabinet section enclosing cabinet-specific electrical arrangement. The apparatus further includes cooling arrangement cooling, the cooling arrangement includes at least one air intake for external air, at least one primary element for filtering the incoming air, at least one fan and at least one air outlet, wherein the fan is arranged cause airflow towards the air outlet. The cooling arrangement includes a cooling air flowpath from a first cabinet section to a second cabinet section, and a secondary element for filtering the cooling air entering the second cabinet section, and an additional fan for creating cooling air airflow into and out from the second cabinet section.

An apparatus, such as a transformer cabinet, includes a housing (e.g., a sheet metal enclosure) having electrical equipment (e.g., a transformer) disposed therein. A duct in the housing is configured to direct a first airflow in the housing to create a vortex that entrains a second airflow that passes over the electrical equipment. The housing may have a first opening configured to provide the first airflow and a second opening configured to provide the second airflow. The first opening may be in a side wall of the housing and the second opening may be proximate a bottom of the housing. The side wall may include a first side wall and the duct may be configured to direct the first airflow upwards and towards a second side wall of the housing.

Aspects of the disclosure generally relate to at least one device for heat transfer or dissipation. The at least one device for heat transfer or dissipation can include an air-to-air heat exchanger. The air-to-air heat exchanger can include an air flow inlet and various slots to establish a flow-through air path.

In some implementations, a network device is provided. The network device includes a housing and a set of switch cards, mounted within the housing. The set of switch cards includes a first set of connectors. The network device also includes a set of line cards having a second set of connectors. The set of line cards are oriented parallel to each other and oriented orthogonally to the set of switch cards. The second set of connectors is coupled to the first set of connectors to couple the set of switch cards to the set of line cards. The network device further includes a first set of power supplies disposed along a left side of the housing and a second set of power supplies disposed along a right side of the housing.
