Analysis of the convection limited and conduction limited：

l  In the case of external convection is limited, the lower heat conduction coefficient plastics can replace the aluminum radiator without increasing the temperature.

l  In the case of heat conduction is limited, the higher heat conduction coefficient plastics can be significantly lower the temperature than common plastics.
