摘要
Abstract
The introduction of a large number of multi-electric devices in hydrogen hybrid airplanes leads to the prob-lems of heat sink mismatch of insufficient heat sink in the climb condition and redundant heat sink in the cruise condi-tion,making it hard to meet the cooling demand.To solve these thermal management problems,this paper carries out research on the multi-heat sink matching scheme and control strategy by modelling the distributed thermal manage-ment system of mainline airliner hydrogen hybrid power system.Firstly,according to the distributed thermal manage-ment system architecture,the solution for middle and final heat sink matching by increasing tank capacity is proposed.Secondly,a simulation model for the distributed thermal management system is established using MATLAB-Simulink software,and the relationship between the middle heat sink capacity and the maximum temperature of the fuel cell is analyzed.Finally,an on-off control strategy is designed based on the enlarged tank.The results show that the distrib-uted thermal management system based on the proposed multi-heat sink matching scheme can meet the cooling de-mands of the hydrogen hybrid power system equipment by increasing tank capacity.The on-off control strategy can re-duce the maximum power of the thermal management system by 16.7%,the energy consumption during the flight pro-file by 55.7%,and the fuel temperature by up to 4.6 ℃,as well as fuel compensation.关键词
