Description

The invention relates to railway transport and can be used in the design of battery cabins of passenger cars.

The purpose of the invention is to increase explosion safety by increasing ventilation by the stool.

FIG. 1 image-agen battery box of the car from the side of the box cover; in fig. 2 shows section A-A in FIG. one; in fig. 3 — casing of the ventilation device, general view; in fig. 4 - the same, top view; in fig. 5 is a section BB in FIG. 3. The battery box of the car contains the top 1, bottom 2, side 3, rear 4, front 5 walls and cover 6. Inside the battery box on the withdrawable carriage 7, batteries 8 are installed. In the bottom wall of the battery box there are ventilation openings suction vent nozzles 9. In the upper zone of the front wall 5, an exhaust vent hole 10 is provided, which is closed by a casing 11 comprising the upper 12, the lower 13 and the front 14 wall. The ventilation channels 15 of the casing 11 are located perpendicular to the side walls of the box 3. On the inner side of the side walls of the casing 11, parallel to the front wall of the box 5, ribs 16 are installed. On the top 12 and bottom 13 walls of the casing 11, holes 17 and 18 are made. The battery box works as follows

shimm way.

Due to the elevated temperature inside the battery case, the weight of the outdoor air column exceeds the weight of the gas column.

VOY mixtures in the box. Under the influence of the weight of these pillars, the mixture enters the exhaust vent hole 10, the vent channel 15 of the casing 11 and outside of the phika. Thus, batteries, being a heat source, are likened to a fan in the sense that, in accordance with their thermal capacity and hydraulic resistance in the path of the air, they exchange air in the car battery pack. In addition, hydrogen, as the lightest gas of a gas mixture, tends to fall into the highest point of the internal cavity of the box, also enters the air vent 10, channel 15 and aperture 17. The passage of the gas mixture with elevated temperature and hydrogen contributes to the slope of the upper wall to the opposite side of the exhaust vent 10, as well as the fact that the upper wall 12 of the housing is a continuation of the inner surface of the upper wall. Simultaneously with the exit of the gas mixture from the air inlet 10 to the air intake pipe 9, air is drawn from the car space.

The front wall of the casing and the fins 16 of the ventilation casing 11 prevent the exhaust vent 10 from being exposed to water, dirt, dust and other particles. When water enters the vent channel 15 by tilting the bottom wall 13 of the casing and the openings 18, it is removed.
