Abstract: A switching device has a housing with an air duct extending between a ventilation opening in a bottom wall and a ventilation opening in a top wall. A rotary shaft extends from a front wall to a rear wall and is rotatably mounted for rotating a coupling device in order to fasten the switching device to a corresponding receiving device. The rotary shaft, which is formed as a hollow shaft, has a middle portion between a first and a second end portion. The middle portion which extends through the ventilation air duct has an outer diameter d. A ratio D/d of a clear width of the air duct and the outer diameter d of the middle portion of the hollow shaft is greater than 1.5.

Abstract: An electronic assembly has a circuit board and two or more heat sinks arranged on the printed circuit board, each having a straight air duct section from an air inlet opening of the heat sink to an air outlet opening of the heat sink. The heat sinks are spaced apart from each other one behind another in a row by intervening spaces, with their air duct sections lying in a straight line and forming an air duct. Through-hole-mounted THT components, which in each case rest against an outside surface of one of the heat sinks, have connecting pins secured in the printed circuit board. A fan generates an air stream that enters the air inlet opening of the heat sink that is located at the beginning of the row and flows through the air duct.

Abstract: An electronics arrangement contains a printed circuit board (PCB), a semiconductor device and a heat sink. A first side of the semiconductor device points toward the PCB and a second side, opposite the first side, bears the heat sink, which is thermally connected to the semiconductor device. A fan is provided for producing an airflow flowing around the heat sink. An air guide device is mounted on the PCB and is configured such that, together with the PCB, it forms an air duct having an air duct inlet and an air duct outlet. The airflow flowing into the air duct flows through the air duct inlet and leaves through the air duct outlet. The air guide device has an air guide ramp that is arranged in the area of the air duct inlet such that the airflow flowing into the air duct inlet is deflected toward the heat sink.

Abstract: Automated deployment of a public cloud is disclosed. The technology accesses, via a user interface, a cloud provider pod designer including a plurality of cloud provider platform components. Instructions comprising a plurality of public cloud requirements are received via the user interface. In addition, optimization suggestions for a cloud provider platform and based on the public cloud requirements are provided via the user interface. The cloud provider pod designer then designs a cloud provider platform. The cloud provider platform is then deployed.

Abstract: A switch is disclosed, in particular a switch disconnector for low voltages, including at least one cuboid pole housing; a switching shaft which runs transversely with respect to the side walls and disconnects contact elements which are resting on one another in order to open the switch; and an aperture opening formed in one wall of the pole housing. In order to prevent the risk of an electrical flashover to the rear wall, it is proposed in at least one embodiment, that the aperture opening is formed in a side wall, to which a channel is connected, which dissipates any overpressure that occurs in the pole housing in an end-face outlet direction.
