摘要：
This paper presents a non-destructive evaluation study on a radiator with cooling fins as a kind of complex shaped specimen. An eddy current testing method, namely multi-frequency excitation and spectrogram method, was employed to detect a removal of radiator cooling fin. Experimental results brought remarkable signal when a fin was removed. Furthermore, the authors discuss the relation between the fin signal and specimen thickness, and concludes the availability for the estimation of thickness of radiator structures.
