AI Technical Summary
When the hydrogen fuel truck is driving in a cold and low-temperature environment in winter, the hydrogen base is prone to freezing, which increases the time and difficulty of hydrogen replacement and affects efficiency.
A centralized hydrogen refueling distributed hydrogen exchange system is designed, using a combination of a warm air nozzle and an ice knocking assembly. The deicing seat is placed on the hydrogen tank module, and the servo motor drives the gears and torsion springs to achieve all-round knocking on the ice and the warm air blowing, reducing the bonding strength between the hydrogen exchange base and the hydrogen tank module.
It effectively reduces the time and difficulty of changing hydrogen, improves the efficiency of changing hydrogen, and ensures that the hydrogen tank replacement is quickly and safely completed in cold environments.
