摘    要:
为获取某航天器运输包装箱在典型高温天气下的极限热控能力,设计了主动控温和被动保温状态试验方案,并开展试验研究。结果表明:太阳辐射是影响包装箱温度的主要因素,环境温度是次要因素;在环境温度为40 ℃、内部航天器初始温度为30 ℃左右的主动制冷工况,该包装箱能将内部航天器温度控制在40 ℃以下要求范围内,且有近7 ℃余量;在环境温度为35 ℃、内部航天器初始温度为25 ℃左右的被动保温工况下,内部航天器温度保持在40 ℃以下的时间约为2 h 15 min。为进一步降低运输过程控温风险、增强包装箱的热控能力,提出了尽量避免阳光直接照射箱体以及增加风扇强迫空气对流等一系列措施和建议。

关 键 词:航天器   运输包装箱   试验研究   主动控温   被动保温   极限热控能力

Abstract:
In order to determine the ultimate thermal control capacity of a certain spacecraft transport package at the typical high temperature, the test schemes about the active heat control and the passive heat preservation are designed, respectively, and the related experimental research is carried out. The results show that the solar radiation is the primary factor affecting the temperature of the transport package; the ambient temperature is the secondary factor. Under the active refrigeration condition where the ambient temperature is about 40 ℃ and the initial temperature of the internal spacecraft is about 30 ℃, the transport package is capable of controlling the spacecraft temperature in the required range below 40 ℃ with a margin of nearly 7 ℃. Under the passive heat preservation condition where the ambient temperature is about 35 ℃ and the initial temperature of the internal spacecraft is about 25 ℃, the transport package can keep the internal spacecraft temperature below 40 ℃ for about 2 h 15 min. A series of measures and suggestions are put forward for avoiding the direct sunlight exposure and increasing the forced air convection of the transport package for further reducing the risk of the temperature control during transportation and thus enhancing the thermal control capacity.
Keywords:spacecraft  transport package  experimental study  active heat control  passive heat preservation  ultimate thermal control capacity
