AI Technical Summary
Existing hydrogen refueling machines lack effective hydrogen cooling devices, which leads to excessively high temperatures in the hydrogen storage cylinders during filling, posing safety hazards. Furthermore, the hydrogen density decreases, resulting in incomplete filling and affecting refueling efficiency.
It adopts a built-in dual-channel hydrogen cooler, which achieves efficient cooling through heat exchange with the coolant. The parallel hydrogen filling branch integrates components such as maintenance valve, filter, solenoid valve, check valve, and mass flow meter to ensure safe, continuous and accurate filling.
Effectively controlling the temperature rise of hydrogen storage cylinders improves filling quality, ensures operational safety, reduces equipment costs and space occupation, and enhances the service continuity and operational efficiency of hydrogen refueling stations.
