Thermal contact resistance (TCR) is a key factor in thermal engineering which affects the thermal-structural design of precision instruments. To reveal the influence of turning morphology on the TCR between potassium dihydrogen phosphate (KDP) crystal and aluminum alloy, a novel simplified model considering two parameters of wavelength and slope is proposed. Meanwhile, the TCR of KDP crystal and aluminum alloy are experimentally investigated to validate this two-parameter model, where the effects of different wavelengths and slopes on Mises stress distribution, temperature distribution, heat flux and TCR can be analyzed. By incorporating the theory of plane turning, the TCR can be reduced by controlling the feed rate and cutting thickness under a certain roughness. This research provides a theoretical basis for the thermal-structural design of crystal modules and the turning of aluminum alloy.

The thermal contact resistance between polymer composites and aluminum alloy is the main parameters of thermal control design in the field of space and its heat transfer mechanism is very complex. This work is to combine experimental and numerical approaches to evaluate the nature of thermal contact between polymer composites and aluminum alloy. Thermal contact resistance between carbon fiber reinforced epoxy composites and aluminum alloy 380 was measured experimentally. And based on the finite element method, the simulations on heat transfer between polymer composites and aluminum alloy have been performed and compared with experiment results. The results show that the thermal contact resistance between carbon fiber reinforced epoxy composites and aluminum alloy is not negligible and strongly correlated with pressure.
