Research on Maintenance Method of Typical Aircraft Electronic Equipment Based on Thermal Analysis Technology

With the development of aircraft manufacturing technology, more and more aircraft types make maintenance more difficult. With the accumulation of maintenance experience, the maintenance level of related technicians is also improving. In recent years, the number of civilian aircraft has been increasing. Not only the number of civilian aircraft is increasing, but also the design and technology are becoming more and more advanced, which requires the continuous improvement of aircraft maintenance technology. The operating temperature of aircraft components is an important factor affecting the service life and reliability of electronic products. This paper mainly analyzes the thermal design method of electronic equipment, expounds the necessity of thermal design in the process of product development, and puts forward some ideas and structural schemes of heat dissipation design, hoping to provide reference for the future design work.
