Description

This is a model for transport of heat without storing it. It may be used for complicated geometries where the thermal conductance G (= inverse of thermal resistance) is determined by measurements and is assumed to be constant over the range of operations. If the component consists mainly of one type of material and a regular geometry, it may be calculated, e.g., with one of the following equations:

  - Box Geometry (flow along length axis):

ThermalConductor_equation1

        k: Thermal conductivity (material constant)

        A: Area of box

        L: Length of box

  - Cylindrical Geometry (radial flow):

ThermalConductor_equation2

        k    : Thermal conductivity (material constant)

        L    : Length of cylinder

        r_out: Outer radius of cylinder

        r_in : Inner radius of cylinder

Typical Values for K at 20 degC in W/(m.K):
