抄録

This paper analytically treats of the heat-flow through the periodically varying thermal-resistance thin layer lain between conductors or the heat-flow between two periodically contacting conductors. During one cycle of the period, p, thermal-conductance of the thin layer temporally changes in a stepwise profile, and takes two different values, Rc and Rd over the time spans, φp and (1-φ) p, respectively. Analytical solution for the effective thermal-conductance, Re, of the thin layer was algebraically approximated using Rc, Rd, φ and the harmonic mean, Rab, of the characteristic thermal-conductances of the two conductors. Algebraical approximation was also made for the maximum temperature amplitude, Δθ*max, arising at the joint ends of conductors. This approximation suggests the following features of Δθ*max, Δθ*max takes the maximum value, (Δθ*max)max, at specified value of φ, φmax, φmax depends only single parameter Rc/Rd, and becomes large with increase of this parameter. On the other hand, (Δθ*max)max depends not only Rc/Rd but also Rd.
