Thermal Conductivity After Coating Aluminium

Thermal Conductivity After Coating Aluminium

Thermal Conductivity After Coating Aluminium

(OP)
Hi,

If the coating has a higher thermal conductivity than the base material of a radiator, does the coating "attract the heat out from the base material"? It would be conduction as the material is coated which I understand on the radiator which is exposed to air flow but how would that compare to a non coated radiator that is also exposed to air flow?

Or would be a case because it is a coating factor, compared with air flow alone, the heat exchange process on the radiator is more concentrated?

Thank You

RE: Thermal Conductivity After Coating Aluminium

A coating has negligible convection affect,but the surface might affect the radiative mode of heat transfer.
