本文对带散热片的散热器作为一种复杂形状的试件进行了无损评价研究。采用涡流测试方法，即多频激励和频谱图法，检测散热器散热片的去除，实验结果表明，当散热片被去除时，信号显著。此外，作者还讨论了翅片信号与试件厚度之间的关系，得出了估算散热器结构厚度的有效性。
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.
