Abstract: An apparatus cools electronic circuitry. An enclosure surrounds the electronic circuitry and has plural surfaces. Air intake holes are disposed in at least one surface and face at least one first direction. Air exhaust holes are disposed in at least another surface and face at least one second direction different than the first direction. A heat sink is in thermal contact with the circuitry and conducts heat generated by the circuitry. When a fan operates, air is drawn from an exterior of the enclosure through the air intake holes, absorbs heat from the heat sink, and then is directed through the air exhaust holes into the exterior of the enclosure. The heat sink is further in thermal contact with the enclosure so that when the fan does not operate, heat is drawn from the circuitry to the enclosure via the heat sink and is dissipated from the exterior.

Abstract: A process and apparatus for regulating the quantity of fresh air in high-speed trains by means of pressure-wave valves. A signal for adjusting a drive unit is determined from the passenger count and outside temperature. This drive unit causes a stop fork to move into a flap stop position of the valve in the "open" operating mode so that the required amount of fresh air can be supplied. The process according to the invention results in a considerable saving on energy, since only the absolutely necessary amount of fresh air need be heated or cooled and the period of time in which ventilation can be used rather than cooling is lengthened.

Abstract: A ventilation control device for a high-speed train carriage is operable in conjunction with a ventilating blower. A deflectable spring flap is mounted to extend across the ventilation duct in the air flow path. When deflection of the flap reaches a threshold level corresponding to possible passenger discomfort, the flap operates a limit switch positioned behind it. This activates a driving solenoid to close a shutter which shuts off the flow through the duct. A timer holds the shutter closed for a predetermined period, after which it is re-opened. Use of a microprocessor-controlled continuous sensor and damper can thereby be avoided, while cutting out very large pressure fluctuations.

Abstract: Ventilating equipment for railway rolling stock including a low-pressure supply air blower, a high-pressure supply air blower, a low-pressure exhaust air blower, and a high-pressure exhaust air blower. This ventilating equipment ventilates car interior during travel of a train outside of tunnels by the low-pressure supply air blower and the low-pressure exhaust air blower, and also ventilates the car interior during travel in tunnels by the high-pressure supply air blower and the high-pressure exhaust air blower. The high-pressure supply air blower and the high-pressure exhaust air blower produce a higher discharge pressure than a changing external pressure during a high-speed travel in tunnels, thereby preventing the propagation of an influence of the changing external pressure into the car interior.
