The present invention relates to a power car for a high-speed train, including: a body; a traction motor; a rheostatic brake; a first ventilation device of said rheostatic brake; electrical control equipment; and a second ventilation device for said electrical equipment. The first ventilation device comprises a first air intake sheath, the inlet and outlet of which are located on the roof of the body. The second ventilation device comprises a second sheath, the inlet and outlet of which are respectively located on the roof of the body and below the body. Each ventilation device comprises a fan arranged in one of the sheaths.

An end carriage that extends between a first free end and a second end intended to be connected to another carriage of the railway vehicle, the end carriage including a lower housing for a bogie made in proximity to the first end. The end carriage further includes at least one conduit, opening on the one hand into the lower housing, and opening on the other hand into the first end of the end carriage, and means for circulating air in the conduit.

An electrically operated vehicle includes a braking resistor in a heat sink cover. The heat sink cover has an air throughflow body having vent openings and an air throughflow direction perpendicular to a direction of travel of the vehicle. The heat sink cover includes an inlet flap on an air inflow side and an outlet flap on an air outflow side. An opening mechanism opens and closes the flaps. In the closed state, the flaps are oriented along the direction of travel and obliquely to the air throughflow direction. In a plan view of the vent openings, the vent openings are at least 90% covered by the flaps in the closed state and at most 60% covered by the flaps in the opened state. The flaps are disposed symmetrically to a vehicle center axis, and the vent openings are oriented parallel to side surfaces of the vehicle.

A waste exhaust ventilation door automatic control device comprises a core body (8), an inner door body (2) and an outer door body (1); wherein the core body is fixed on a ventilation opening of the waste exhaust ventilation door, a top of the outer door body is movably hinged on an outer side of the core body, and a bottom of the inner door body is movably hinged on an inner side of the core body; when there is no pressure fluctuation outside the core body, the outer door body and inner door body will open, and when there is pressure fluctuation outside the core body, the outer door body and/or the inner door body will be closed automatically due to a pressure difference between inside and outside the core body. A vehicle body comprising the waste exhaust ventilation door automatic control device is also provided.

The article transport vehicle travels with its wheel rolling on the travel surface provided on the upper surface of the travel rail. The travel rail has a peripheral wall that includes a surface on which the travel surface is formed, and an internal space that is enclosed by the peripheral wall, and extends along the travel path. The travel surface has a through hole that passes through the peripheral wall, and brings the internal space into communication with an external space. The travel rail is provided with a suction device that is in communication with the internal space, and is configured to suck air in the internal space. The internal space is closed except for the through hole, and a connection portion for the suction device.

A car air-conditioning duct guides air to a suction side of an air conditioner mounted on a car or guides the air flowing from a blow-off side of the air conditioner. The car air-conditioning duct includes a duct wall having a tubular shape and forming a duct outer surface and a duct inner surface. The duct wall is made of a composite foamed resin material containing polystyrene resin and polyolefin resin.

A health protection system and a method for passengers on a train in a polluted indoor environment are provided. The health protection system includes a basic data acquisition module, an outdoor air quality prediction module, an indoor air quality prediction module, and a ventilation strategy generation module, wherein the basic data acquisition module acquires basic data; the outdoor air quality prediction module predicts outdoor air quality of the train; the indoor air quality prediction module predicts indoor air quality of the train; and the ventilation strategy generation module generates a ventilation strategy and achieves health protection of the passengers on the train. The method includes: predicting indoor and outdoor air quality data information of the train according to the acquired indoor and outdoor air quality data of the train; and generating a corresponding ventilation strategy according to the indoor and outdoor air quality data of the train.

Provided is an air flow regulator for a railway vehicle, which is configured so that the rattling of bars can be prevented without using welding, an affixation member, etc. An intake grill is provided at an intake opening for sucking air from an interior of a railway vehicle. The intake grill comprises a frame, bars (40), and a deformation means. The frame defines an outer edge of the intake opening. The bars (40) are plate-shaped members spanned between portions of the frame to connect the portions to each other. The deformation means elastically deforms the bars (40) to generate reaction force therein.

Embodiments of the disclosure can relate to a ceiling mounted air distribution system for a railcar. According to one embodiment of the disclosure, a ceiling-mounted air distribution plenum may include: a diffuser configured to transmit air to at least one first air channel, the at least one first air channel having a first end configured to couple to the diffuser, a second end distal from the first end; at least one second air channel disposed proximate to and longitudinally with the at least one first air channel, the at least one second air channel having a first end configured to couple to the diffuser, a second end distal from the first end, and at least one air distribution hole, and at least one channel divider disposed to separate the at least one first air channel and the at least one second air channel.

The cooling device (12) according to the disclosure includes a case (20), designed to be arranged on a roof (16) of the vehicle, said case (20) comprising two side walls (22) and one upper wall (24) together delimiting a housing for each component. Each housing forms an air guiding duct in which the corresponding component is housed, said duct extending between at least one side air inlet opening (32) arranged in one of the side walls (22) and one upper air outlet opening (34), arranged in the upper wall (24).
