摘要

电动垂直起降飞行汽车（eVTOL）是未来城市空中交通发展的可选择技术路线之一，但其动力电池高散热功率需求和应用场景的多变性对热管理系统发起巨大挑战。为解决该难题，设计了多场景eVTOL集成热管理框架，能够同时满足电池和乘员舱的热管理目标。基于Amesim仿真软件搭建了eVTOL热管理仿真平台，研究飞行条件对热管理和续航里程的影响。仿真结果表明：地面温度较高时，提高巡航高度可以减少热管理能耗，巡航温度在10~26 ℃时最大减少4 kW的热管理能耗；执行紧急救援任务时，悬停救援时间超过150 s会造成电池内部温差过大；低有效载荷有利于提升续航里程，空载是满载续航里程的1.33倍。

Abstract

An electric vertical take-off and landing flying vehicle (eVTOL) is a potential technology for future urban air mobility. A major challenge for thermal management systems is the high cooling requirement and the variable application scenarios. To overcome this challenge

a multi-scene eVTOL-integrated thermal management system was developed. In this study

an eVTOL thermal management simulation platform based on Amesim simulation software was developed to investigate the effects of flight conditions on thermal management and range. The simulation results show that increasing the cruise altitude can reduce the thermal management energy consumption when the ground temperature is high. The maximum reduction of energy consumption for thermal management energy is 4 kW when the cruising temperature ranges from 10 ℃ to 26 ℃. When the hovering rescue duration is more than 150 s during the emergency rescue operation

the temperature difference inside the battery becomes too pronounced. A reduced payload improves the range

with the unloaded range being 1.33 times greater than the fully loaded range.
