摘要：

Thermal control is one of the most crucial problems for electronic devices on nuclear emergency rescue robot due to the harsh operating conditions. Phase change material (PCM) based heat sink and heat insulation layers, serving as a passive thermal control system, were applied for motor driver as a case for electronics protection on nuclear rescue robot. Two types of PCM based thermal control systems for both room temperature and elevated temperature environments were proposed considering the nuclear accident condition. The anti-irradiation property of an organic commercial PCM OP44E was studied. Experiments were conducted to investigate effects of system structure and heat source power on the temperature control. Results showed that the system can greatly prolong the motor driver's safe running time for more than 1 hour without any power consumption. The best working time was almost linearly decreased with the increase of the input power. High temperature test at 100 degrees C indicated that the motor driver could safely operate for more than 98 min. The PCM based support frame increased 54% of the best working time.
