線形化法による矩形放射放熱フィンの温度分布計算

抄録

An infinite series solution presented for a thin rectangular fin is developed for the steady temperature distribution in a two-dimensional rectangular sandwich panel fin heated within a rectangular footprint region, and losing energy to environment by linearized radiation. The solutions approximate a spacecraft application where a heat dissipating electronic component is mounted to a heat-sink plate or a equipment panel. The comparison of numerical results obtained from the proposed method and the lumped nodal method shows that the formulations will be useful in evaluating heat-sink designs where geometry, heat loads, thermal properties, and environmental parameters change frequently.
