The invention discloses a liquid hydrogen refrigerating system for a fuel cell cold-chain logistics vehicle. A liquid hydrogen storage tank discharges liquid hydrogen outwards, and the liquid hydrogenenters a heat exchanger and a regenerator through an on-off controllable pipeline. Liquid hydrogen releases cold energy in the heat exchanger and the regenerator, and the cold energy is heated and converted into low-temperature hydrogen. Low-temperature hydrogen can enter a fuel cell using channel to be used by a fuel cell. And a secondary refrigerant flows out of a cold plate and is led to the heat exchanger or the regenerator. The secondary refrigerant completing cold transfer in the heat exchanger and the regenerator returns to the cold plate through the on-off controllable pipe, and the cold is transferred to a refrigerated truck carriage. On the basis that conversion from liquid hydrogen to hydrogen is completed and the hydrogen supply requirement of the fuel cell is met, liquid hydrogen cold energy utilization is achieved, the energy utilization efficiency is improved, the energy-saving and environment-friendly development requirement is met, and wide development prospects are achieved.

    本发明公开了一种本发明公开了一种用于燃料电池冷链物流车的液氢制冷系统。本发明的液氢储罐向外排放液氢,分别通过通断可控管路进入换热器和蓄冷器。液氢在换热器和蓄冷器中释放冷量,升温转化为低温氢气。低温氢气可进入燃料电池使用通道供燃料电池使用。载冷剂从冷板中流出,通往换热器或蓄冷器。在换热器和蓄冷器中完成冷量传递的载冷剂,经过通断可控的管回到冷板,将冷量传递给冷藏车厢。本发明在完成液氢到氢气的转变,达到燃料电池供氢要求的基础上,实现液氢冷能利用,提高能量利用效率,符合节能环保的发展要求,具有广阔的发展前景。
