As a core component of aircraft thermal management systems, the plate-fin heat exchanger (PFHE) plays a decisive role in determining the system’s thermal safety limits. Local temperature non-uniformity within PFHEs is a key factor that degrades heat transfer efficiency. To overcome limitations of traditional performance evaluation models and localized thermal monitoring techniques, this study develops a comprehensive evaluation model incorporating non-uniformity parameters and implements a localized temperature monitoring system using fiber Br...
