为确定环路热管用于机载电子设备散热的适用性,讨论了应用于航空电子设备冷却的环路热管冷凝器可用热沉,提出将机翼蒙皮作为环路热管冷凝器的热沉.通过机翼蒙皮的传热分析,计算了飞行任务包线下机翼蒙皮内表面温度,以确定环路热管冷凝器热沉温度范围.理论计算表明,利用环路热管将机载电子设备的热量耗散于飞机蒙皮是一种可行的热管理技术. In order to determine the applicability of the loop heat pipe for the heat dissipation of airborne electronic equipment, the available heat sink for the loop heat pipe condenser used in the cooling of avionics is discussed. The wing skin is proposed as the heat sink for the loop heat pipe condenser. Based on the heat transfer analysis of wing skin, the temperature of the inner surface of wing skin of flight envelope was calculated to determine the temperature range of loop heat pipe condenser.The theoretical calculations show that the use of loop heat pipe to airborne electronic equipment The heat dissipation in aircraft skin is a viable thermal management technique.
