Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of hydrogen energy logistics vehicles, in particular to a hydrogen bottle heat insulation structure of a hydrogen energy logistics vehicle. BACKGROUND

[0002] The working temperature of the fuel cell stack in the hydrogen energy automobile is relatively high, and is generally required to be controlled between 75-85 DEG C. Therefore, the fan exhaust temperature of the radiator assembly of the hydrogen fuel cell stack is close to 80 DEG C under extreme working conditions. According to the professional requirements of the hydrogen supply system, the hydrogen bottle group needs to be as far away from the heat source as possible. Due to the limitation of the space layout of the whole vehicle, the relative position of the radiator assembly and the hydrogen bottle group of the hydrogen energy logistics vehicle is relatively close, and the heat discharged by the radiator assembly will affect the hydrogen bottle.

[0003] The existing patent (application number: CN202121462874.0) proposes a hydrogen energy logistics vehicle hydrogen bottle heat insulation structure and hydrogen energy logistics vehicle, which comprises a heat insulation cover. The heat insulation cover is arranged in the same direction as the hydrogen bottle and is arranged in an inverted U shape in the cross section. The heat insulation cover is matched with the hydrogen bottle and is installed on the periphery of the hydrogen bottle. The lower end of the heat insulation cover is used for connecting with the hydrogen bottle frame, and one side is used for installing between the hydrogen bottle and the radiator assembly. The material of the heat insulation cover is heat insulation material. The heat insulation cover is arranged between the radiator assembly and the hydrogen bottle group, which can protect the hydrogen bottle and effectively block the influence of the heat discharged by the radiator assembly on the hydrogen bottle, thereby effectively improving the problem of reduction of hydrogen carrying capacity of the hydrogen bottle after being heated.

Under complex automobile driving conditions, the hydrogen cylinder is prone to vibration, rotation and slipping. At the same time, the high temperature environment and sudden impact of the outside world will have a great impact on the whole hydrogen supply device, which is easy to cause damage to the hydrogen cylinder, even explosion, and there is a great safety hazard.
