Prediction of thermal contact resistance between polished surfaces

Continuous-wave laser particle conditioning: Thresholds and time scales

“…Using a 10 µm hemisphere for the model particle, the contact conductance is estimated at 46 kWm −2 K −1 . This value initially seems high in comparison to metal-metal contacts which have a conductance on the order of a few kWm −2 K −1 [9], however the contact conductance of graphene and highly ordered graphite can easily be tens of MWm −2 K −1 [10]. The loose bonding of the graphite with the surface of the optic and the agglomerated nature of the graphite flakes may explain the lower value calculated.…”

Nanoclay Paste as a Thermal Interface Material for Smooth Surfaces

“…A typical thermal solution for a microelectronic system utilizes a thermal interface material (TIM) [1][2][3][4][5][6] between the die and the heat spreader, and between the heat spreader and the heat sink. The TIM is used to reduce the contact resistance arising from the incomplete contact between two solid surfaces.…”

The Parameters Affecting on Thermal Contact Conductance-a Review

“…Numerical results show that the long wavelength cut-off has an important effect on the contact conductance, whereas the sampling interval and the fractal dimension are less important. [25] In this study guarded hot plate method for thermal conductivity measurements was choosen to determine temperature drops across interfaces. It was shown that a general theory can be modified to give a good estimation of the thermal resistance with a variety of interface materials.…”
