A server rack with a plurality of compute nodes is positioned in a facility that includes a spine and the server rack includes a middle of rack (MOR) switch located near the middle of the server rack, vertically speaking. The MOR switch includes a plurality of ports that are connected via passive cables to the compute nodes provided in the server rack. In an embodiment the passive cables are configured to function at 56. Gbps using non-return to zero (NRZ) encoding and each cable may be about or less than 1.5 meters long. An electrical to optical panel (EOP) can be positioned adjacent a top of the server rack and the EOP includes connections to the MOR switch and to the spine, thus the EOP helps connect the MOR switch to the spine.

A plenum for processing one or more byproducts output from a generator, and systems and methods thereof, can have the plenum in the form of a hollow elongate rectangular box having a first end and a second end opposite the first end. The plenum can have a frame and a sidewall fixed to the frame, and can be adapted to be oriented vertically when operatively coupled to receive the one or more byproducts from the generator. The sidewall can include an opening adapted to receive heated air from the generator as one of the byproducts from the generator.

A telecommunication cabinet includes a first and a second cabinet bodies, an internal fan, a partition board, multiple heat dissipation pipes and an external fan. The first cabinet body includes an upper slot and a lower slot. The second cabinet body covers the first cabinet body and includes an air inlet and an air outlet. The internal fan is arranged in the first cabinet body. The partition board is connected with the second cabinet body and includes multiple air vents and multiple air intakes. The heat dissipation pipes are disposed in the second cabinet body and include multiple upper nozzles and multiple lower nozzles. Multiple heat dissipation channels are disposed between the heat dissipation pipes. The external fan is disposed on a bottom inside the second cabinet body.

A ventilation and heat dissipation apparatus and an electromechanical device is provided. The apparatus includes: a main frame configured to connect to a device to be ventilated and cooled, and a ventilation and heat dissipation assembly located inside the main frame. The ventilation and heat dissipation assembly includes a waterproof unit, an external ventilation unit, and an internal ventilation unit. The waterproof unit is located between the external ventilation unit and the internal ventilation unit, and the external ventilation unit and the internal ventilation unit are arranged in a staggered manner. A bottom of the waterproof unit is provided with a drainage hole. External rainwater is prevented from entering the device, outside air enters the main frame through the external ventilation unit, and heat generated during operation of the device enters the main frame through the internal ventilation unit, for heat exchange.

A computing system includes a cabinet, an inlet temperature sensor, a cooling device, an environmental sensor, and at least one processor. The cabinet houses at least one computing device. The inlet temperature sensor is configured to detect inlet temperature data for the at least one computing device. The inlet temperature data represents internal temperature within the cabinet. The cooling device is coupled to the cabinet for maintaining temperature within the cabinet. The environmental sensor is configured to detect environmental temperature data external to the cabinet. The environmental temperature data represents external temperature outside the cabinet. The at least one processor is configured to: (a) determine if one or more of the inlet temperature data and the environmental temperature data exceeds a temperature range; and (b) in response to the temperature range being exceeded, generate a first warning signal indicating a temperature problem.

A network switch device includes cooling fans to remove heat generated by its electronic circuitry during operation. Multiple cooling zones are provided in a network switch device to enable reduced cooling fan power consumption. The switch device includes a baffle positioned between a first zone and a second zone and across a circuit board. A first cooling fan provides a first airflow through the first zone and across a first portion of the circuit board positioned within the first zone. A second cooling fan provides a second airflow through a second zone of the housing and across a second portion of the circuit board positioned within the second zone. The baffle directs the first airflow away from the second zone and directs the second airflow away from the first zone. Fan speeds of fans in a cooling zone may be adjusted based on temperature sensors positioned in that zone.

An assembly includes a lower sub-assembly containing a first fan, a middle sub-assembly supported above the lower sub-assembly, a bottom air flow control plane supported in the middle sub-assembly and having openings sized to fit multiple computers having vertical cooling air paths, and a top air flow control plane supported in the middle sub-assembly above the bottom air flow control plane and having openings sized to fit the multiple computers such that air is forced through the vertical cooling air paths.

A system for storing data includes a rack, one or more data storage modules coupled to the rack, and one or more data control modules coupled to the rack. The data storage modules may include a chassis, two or more backplanes coupled to the chassis, and one or more mass storage devices (for example, hard disk drives) coupled to the backplanes. The data control modules may access the mass storage devices in the data storage modules.

A control cabinet for at least one electrical drive controller includes a control cabinet housing a first cabinet compartment formed in the control cabinet housing and having at least one inlet opening for fresh air, at least one first transfer opening and a fresh air duct flow-connecting the inlet opening to the first transfer opening. A second cabinet compartment is formed in the control cabinet housing and has at least one outlet opening for exhaust air, at least one second transfer opening, and an exhaust air duct flow-connecting the outlet opening to the second transfer opening. A third cabinet compartment is formed in the control cabinet housing and is sealed off in terms of flow from the first cabinet compartment, the second cabinet compartment, and the environment outside the control cabinet. A partition delimits the third cabinet compartment in terms of flow from the first cabinet compartment and the second cabinet compartment, and has the at least one first transfer opening and the at least one second transfer opening. The third cabinet compartment is in the form of a rack with at least one drawer, wherein each drawer is designed to receive an insertable control device.

The invention concerns a helicopter ventilation architecture, said helicopter comprising at least two avionics bays (112a, 112b) comprising electronic equipment (116a, 116b) to be ventilated, said architecture comprising, for each avionics bay, an air inlet (120a, 120b) allowing outside air to enter the avionics bay in order to ventilate said avionics bay, and an air outlet (124a, 124b), allowing the air ventilating the avionics bay to exit the avionics bay, characterised in that the ventilation architecture further comprises a mixing chamber (134), connected to the air outlets, configured to receive the air originating from all the avionics bays, at least one air duct (138a, 138b), connected to the mixing chamber and to an outlet (130a, 130b) for discharging the air to the outside, and at least two fans (128a, 128b), arranged and distributed in the air duct or ducts.
