摘　　要：新能源汽车目前使用最多的区域是我国西北、东北及国外的中亚、南亚、西亚等自然环境干热及干冷的环境。在自然环境干热干冷的条件下,易熔合金会发生变化甚至失效,导致各类汽车泄漏甚至自燃事故。通过研究自然干热干冷环境下的易熔合金性能变化,调整其熔化温度,可以有效减少相关事故发生。At present, the regions where new energy vehicles are most used are the dry hot and dry cold nat-ural environments in the northwest and northeast of China, as well as in Central Asia, South Asia and West Asia abroad. Under the condition of dry heat and cold in the natural environment, fusible alloys will change or even fail, leading to various types of automobile leakage and even spontaneous combustion accidents. By studying the performance changes of fusible alloys under natural dry heat and cold environment and adjusting their melting temperature, the occurrence of related accidents can be effectively reduced.
