Design and Optimization of Double-pipe Heat Exchanger for Cold Energy Recovery in Liquid Hydrogen Refueling Stations
摘要
Abstract
To achieve fast filling times for fuel cell electric vehicles,it is necessary to precool the hydrogen before dispensing.Traditional precooling systems rely on external refrigeration cycles,significantly increasing the energy consumption and operating costs of hydrogen refueling stations.This work proposes integrating thermal management system into liquid hydrogen refueling stations,utilizing a double-pipe heat exchanger and the refrigerant R1233zd(E)to recover cryogenic cold energy from liquid hydrogen,enabling hydrogen precooling without external cooling input.A numerical model of the double-pipe heat exchanger was developed to analyze the heat exchange process,the effects of fluid and material temperature variations on heat transfer,refrigerant freezing risks,pressure drop,and pump energy consumption was considered,thereby optimizing the heat exchanger design.Results indicate that the system achieves a cold energy recovery rate of 1 800 to 2 000 kJ·kg-1 with a pump power consumption of approximately 2 500 W,aiding in designing of cold energy recovery in liquid hydrogen refueling stations.关键词
