Generally, a hydrogenation station carries out hydrogenation by filling under three pressures of low pressure, medium pressure and high pressure, and due to the coke-soup effect of hydrogen, when a hydrogenation machine of the hydrogenation station is filled at a high flow rate, a hydrogen storage cylinder of a vehicle-mounted hydrogen supply system cannot radiate heat in time, so that the temperature of the hydrogen rises. At present, the 35MPa vehicle-mounted bottle in China is a high-pressure hydrogen storage bottle with an aluminum liner and carbon fiber fully wound, and the use environment temperature is-40-85 ℃. In order to ensure that the temperature of the bottle does not exceed the service temperature of the bottle after the whole filling is finished even when the environmental temperature is higher in summer. Therefore, the temperature rise in the filling process needs to be controlled, and how to prevent the hydrogen temperature from continuously rising is one of the key performances of the hydrogenation machine. At present, the main domestic 35MPA hydrogenation machine manufacturers mainly adopt a pre-cooling mode before hydrogenation in the aspect of hydrogen temperature rise during filling. Before hydrogen enters the hydrogenation gun, heat exchange is carried out through an external heat exchanger, so that the temperature of the hydrogen is reduced, and then the hydrogen is filled into the vehicle-mounted bottle through the hydrogenation gun. The cooling medium of the heat exchanger is low-temperature circulating cooling water, and a high-power water chilling unit needs to be arranged outside to reduce the temperature of the cooling water to 5-10 ℃, so that the energy consumption is high.
