Liquid hydrogen refrigerating system for fuel cell cold-chain logistics vehicle

Abstract

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.

Description

technical field [0001] The invention belongs to the field of refrigeration systems for refrigerated transport goods vehicles, and in particular relates to a liquid hydrogen refrigeration system for fuel cell cold chain logistics vehicles. Background technique [0002] With the rapid development of my country's economy and the gradual improvement of people's living standards, the demand for food diversity continues to increase. When food is stored at room temperature, the color, aroma, taste and nutritional quality will change and the quality will decrease. If it is stored at room temperature for a long time, food deterioration and spoilage will occur. Therefore, it needs to be transported at a relatively low temperature to ensure that the food is in a fresh state. In recent years, the number of cold chain logistics vehicles has been increasing. At present, the refrigeration system of traditional cold chain logistics vehicles is usually a mechanical refrigeration system, w...
