A structure of a split-discharge hydrogen cylinder for a vehicle

Abstract

The invention discloses a divertable discharge type hydrogen cylinder for vehicles, which belongs to the technical field of gas cylinders. The outlet of the channel is arranged on the side wall of the raised part of the hydrogen cylinder to reduce the layout space of the hydrogen cylinder itself, and the tail of the hydrogen cylinder is used to arrange the diversion flow. The device is used to release hydrogen in different situations, including: a bottle body with channels at both ends of the bottle body. The channels at both ends of the bottle body are different in shape and have multiple outlets connected to the outside world. Bifurcated mouth; diversion device, located at the bifurcation of the channel at the end of the bottle body, and the radius of the diversion device is greater than the cross-sectional radius of the channel at the end of the bottle body, the diversion device is hollow and has multiple openings, and the temperature control device is provided in the diversion device Switch, the temperature control switch can selectively block the outlet at the rear end of the bottle, so that the airflow in the bottle can be discharged from the set outlet.

Description

technical field [0001] The invention belongs to the technical field of gas cylinders, and in particular relates to a structure of a split-discharge-discharging hydrogen cylinder for a vehicle. Background technique [0002] Although hydrogen is a flammable and explosive gas, hydrogen is also an important component of fuel cells, so its storage technology is directly related to the battery life, cost and safety of hydrogen fuel cell vehicles. Hydrogen is usually stored in special hydrogen cylinders. Due to the high internal pressure, if the temperature and pressure in the hydrogen cylinders are too high due to environmental and other factors and cannot be released in time, it will often cause an explosion and a safety accident. [0003] The inventor believes that at present, the front end of the hydrogen cylinder is usually connected to a separate integrated valve. This method increases the layout space of the hydrogen cylinder on the vehicle. If the vehicle is bumpy, there wi...

Hydrogen is usually stored in a special hydrogen cylinder, because of its high internal pressure, if the temperature and pressure in the hydrogen cylinder are too high due to environmental and other factors and cannot be released in time, it will often cause an explosion and a safety accident

[0003] The inventor believes that at present, the front end of the hydrogen cylinder is usually connected to a separate integrated valve. This method increases the layout space of the hydrogen cylinder on the vehicle. If the vehicle is bumpy, there will be a problem of collision between the integrated valve and the side wall of the vehicle body; At the same time, a thermal fuse is installed at the tail of the hydrogen cylinder to ensure that when the hydrogen temperature in the bottle is too high, the thermal fuse will be blown to release the hydrogen from the tail of the bottle. In this way, after the thermal fuse is blown once, it needs to be replaced, greatly Affect the use efficiency of hydrogen cylinders
