摘要：

Because the high performance of avionics equipment is required, the heat dissipation design of electronic devices has become necessary. If the heating value of electronic devices is not adequately controlled, malfunction and degradation might occur during operation. In this study, we produced, analyzed, and tested cooling devices of avionics equipment for heat dissipation and compared them. In addition, we used the heat transfer block made of a heat pipe, aluminum, and copper. From the test results, the maximum temperature of the heat pipe was 142.3 degrees C, which was 18.0 degrees C and 12.7 degrees C lower than those of aluminum and copper, respectively. The temperature deviation was lower than that of aluminum and copper at 27.2 degrees C and 17.0 degrees C, respectively. Hence, the heat pipe exhibited the best heat transfer performance. Furthermore, we verified the safety of the working fluid inside the heat pipe.
