We measured the steady contact thermal resistance between two aluminum plates by changing parameters: surface roughness, contact pressure, fluid in the space, and distance of the space. We found that effective ways to change the contact thermal resistance are to change distance of the space and to change fluid in the space. Then we experimented on the dynamic change of contact thermal resistance by changing distance of the space using vacuum or non-vacuum conditions in the space. The results show that the contact thermal resistance can be changed every 5 s with the changing rate of 30%.
