Several Problems in the Thermal Contact Resistance Research of Solid Interfaces at Low Temperature

摘要

According to our experiences in the research of the thermal resistance between solid interfaces at low temperature, some modeling problems such as surface topography, the interface deformation and the improvement of thermal contact of the solid surfaces are introduced in this article. A new thermal contact fractal model is developed. The novel measure equipment is developed which is capable to measure the thermal conductivity and the thermal contact resistance between solid surfaces simultaneously and the test error is analyzed. The experimental results were compared with the prediction data.
