Cross Connect Thermal Conductor

Cross Connect Thermal Conductor connecting two Node or Shape components with contact area of each node, input from real vector signals.

  

Description

The Cross Connect Thermal Conductor component is used for connecting two Node or Shape components with all combinations of heat path.

This component can also take account of normalized contact area ratio between two Node or node of the Shape from two real vector signals, Ac_ai and Ac_bi.

The order of coefficients of normalized contact area ratio Ac_a and Ac_b are as follows:

a1b1, ... ,a1bm,a2b1, ... ,a2bm, ...... ,anb1, ... ,anbm

For example, when Nodes_a = 2 and Nodes_b =3, Ac_b4 means a2b1,the coefficient of normalized area ratio of port_b side between port_a2 and port_b1.

When using this component, connect port_a and port_b to port_center of Node or Shape components, and input two real vector signals of coefficient of normalized contact area ratio (0 to 1).

The following image illustrates the behavior of the Cross Connect Thermal Conductor component in the case of numNode_a=2 and numNode_b=3. There are 2×3=6

Equations
Heat conductance G__off is used for the heat path without heat flow.
