装甲车辆绝大部分由金属材料制成。由于金属比热小、导热快 ,故受环境温度影响较大 ;加上车内空间狭窄 ,关窗行驶时舱室密闭 ,空气对流差 ,散热困难 ;车内热源多 ,如发动机、车载电子设备、枪炮射击等 ,特别是在高温环境下行驶 ,装甲车辆舱内的高温将直接影响乘员的身心健康及 The vast majority of armored vehicles made of metal. Due to the small specific heat of metal, fast heat conduction, it is greatly affected by the ambient temperature; plus a narrow space inside the car, close the window when the compartment closed, poor air convection, cooling difficulties; Gunshots, etc., especially at high temperatures, the high temperatures in the armored vehicles compartment will directly affect the physical and mental health of the occupants and
