目的 以同位素热源产品贮存任务剖面为背景，研究在贮存状态下含热源自发热产品的传热特性。方法 搭建含热源自发热产品热试验平台，对不同贮存状态下含热源自发热产品的热状态进行实验研究，分析有、无风，有、无包装箱条件下产品的传热特性。结果 裸球状态有风条件下传热性能较好，加厚包装箱内的发热球体和球壳组件温度比常规包装箱高。结论 2种状态下各测点温度随着离热源距离的增加而下降，裸球和常规包装箱状态下各测点温度随测点相对位置的增大，其下降趋势逐渐减小。研究结果可为产品热设计及后期环境热考核试验作理论支撑。

The paper aims to research the heat transfer characteristics of spontaneous heating products containing heat source under storage conditions based on the background of the storage task profile of radioisotope heat source product. The experiment platform of spontaneous heating product including heat source was built. The thermal state of product containing heat source under different storage conditions was studied experimentally. And the heat transfer characteristics of product with or without packaging box in or not in the wind were analyzed. The heat transfer ability of product without packaging box under windless conditions had good performance. Furthermore, the temperature of the hot sphere and spherical shells in the thicker packaging box was higher than that in the common one. The temperature of measuring points under the two conditions decreases with the increase of distance from the heat source. And the downtrend of the temperature of measuring points of the product without packaging box or with the common one decreases with the increase of the relative distance. The research results can be used as theoretic support for thermal design and later environmental thermal testing of product.
