General

The theory is explained in the document Interleaved Fin Connectors.


Inputs

Length
Is the length of the connector.

Width
Is the width of the connector.

Overlapping
Is the portion of the fin height enclosed by the gap.

Fin cond
Is the thermal conductivity of the fin material.
For various materials see: Tools from Maya

Fin height
Is the height of the fins.

Fin thickness
Is the thickness of the fins.

Fin count
Is the fin count for the bottom part.

Gap width
Is the fin-to-fin distance. This input is not edible. The value is adjusted on mouse exit from on of the fin count, fin thickness and width inputs.

Gap cond
Is the thermal conductivity for the gap material.
