| 摘 要： | 对一种空间实验装置中电子箱热控制系统的关键热控元件——散热板内嵌热管的传热能力进行了热分析计算.采用热容热阻网络法,建立了非规则截面槽道热管的传热模型,在传热网络分析的基础上,以热管No.21和热管No.22为例,选取空间实验装置在最热工况下稳定运行和最冷工况下从启动到稳定运行两种实验边界条件,计算了热管的传热能力,并与西班牙IberEspacio热管公司提供的传热极限数据进行了比较.结果表明,全部内嵌热管都能在传热极限范围内可靠运行,其中最热工况和最冷工况下热管的最大传热能力分别为工作温度41.7℃时的74.9W·m和-9.3℃时的69.6W·m. |

| Abstract: | To secure the reliability of a thermal control system for an electronics system of a space experiment system,a thermal analysis of heat transport capacity was performed for the embedded heat pipes,which are the key thermal control devices for a wake radiator.A heat pipe thermal model was created based on the non-regular cross section applying the method of thermal capacitor-resistor network.After clarifying the thermal network of the heat pipe,No.21 and No.22 heat pipes served as examples to illustrate the ... |
