基于液体冷却的综合热能管理系统设计与仿真

Design and simulation of thermal management system based on liquid cooling

在新一代飞行器高性能的需求下,高功率电子设备产生的高热量给飞机冷却系统提出了新的挑战。然而传统的机载机电系统相互独立发展,热量不能互补和有效利用。国外在上世纪已开展综合热能管理系统的研究,但国内发展较为缓慢,鲜有成熟报道。提出了一种基于液体冷却的综合热能管理系统设计方案,将飞机全飞行过程中的不同任务阶段和相应机载子系统的热载荷综合考虑,实现热量的有效利用。AMESim仿真结果表明,设计的系统可以满足飞机机载系统在不同飞行阶段甚至特殊大机动飞行任务下的冷却需求,同时降低了飞机的代偿损失,使飞机性能得到较大提升。

Under the demand of next-generation high-performance aircraft, great heat produced by high-power electronic equipment poses a challenge to the aircraft cooling system. However, traditional air-cycle refrigeration systems are distributed in individual electromechanical subsystem, heat cannot be utilized effectively. Foreign researchers started the research of thermal management system(TMS) in the last century, while relevant research was rarely reported in domestic. In this paper, a TMS design scheme based on liquid cooling was proposed considering various flying stages and subsystems. AMESim simulation results manifest the effectiveness of the proposed scheme.
