Prediction of interfacial filler thickness for minimum thermal contact resistance
Abstract
A theoretical optimization procedure to establish the appropriate filler thickness for minimizing thermal contact resistance between flat non-wavy surfaces is developed and demonstrated. The analysis is founded upon the assumption of ideal plastic asperity deformation at the interface formed between randomly rough surfaces separated by the softer filler material. Experimental measurements of the thermal contact resistance for various contact assemblies are presented to verify the prediction.
