摘要

PROBLEM TO BE SOLVED: To provide an equivalent thermal conductivity calculation device and method, capable of performing calculation with high accuracy.;SOLUTION: This equivalent thermal conductivity calculation device for a composite material has: an input means inputting conditions; and an output means outputting equivalent thermal conductivity regarded as thermal conductivity equivalent to thermal conduction from a conducting boundary to a conducted boundary when configuring by a single member. The equivalent thermal conductivity calculation device has: a physical property input means having a model allowing condition determination by specification of a size, a shape and a physical property value, and prompting input of a size, a shape and a physical property value; an element division means performing element division after fitting the inputted shape to the model; a boundary condition input means prompting input of boundary conditions; a node temperature determination means calculating a temperature of a node; and a thermal conduction calculation means calculating the equivalent thermal conductivity on the basis of the temperature of the node.;COPYRIGHT: (C)2005,JPO&NCIPI
