Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen storage bottle accessories for a vehicle-mounted hydrogen system, and in particular to a cooling device for a hydrogen storage bottle. Background Art

[0002] The onboard hydrogen system is an important component of fuel cell vehicles. It provides fuel for the fuel cell engine, which is equivalent to the fuel tank of a traditional gasoline vehicle. The hydrogen storage bottle is the core component for storing hydrogen fuel for fuel cell vehicles. The quality of hydrogen stored in the hydrogen storage bottle is related to the vehicle's endurance performance and is one of the important indicators of fuel cell vehicles.

[0003] However, the existing on-board hydrogen system is prone to heat up during the refueling process, which causes the internal pressure of the hydrogen storage bottle to be too high, which in turn causes the gas to be filled less than the standard value, affecting the vehicle's range.
