PHOTO-ACOUSTIC MEASUREMENT OF THERMAL CONTACT RESISTANCE BETWEEN SOLID PLATES
Аннотация
Recently, in thermal design which has become complicated, it is important to estimate the thermal contact resistance correctly. In the present study, the application of a photo-acoustic method, which is one of the non-contact and non-destructive methods for the thermal properties of various materials, to the measurement of the thermal contact resistance between solids was examined experimentally. As a result, it was turn out to be able to understand the thermal contact resistance based on the data of maximum phase lag of the photo-acoustic signal to the modulated irradiation light. Compared with the measured result by a steady-state method, a similar tendency was recognized, and the thermal contact resistance of the same order could be obtained quantitatively.
