Anodizing AL....thermal conductivity?
Anodizing AL....thermal conductivity?
(OP)
as the topic states, im interested in how anodizing AL effects its thermal properties. the application in mind is a front mount intercooler or heat exchanger used on high performance automotive applications. does the anodization reduce the thermal conductivity? does it change for different types, such as normal or hard anodizing?
thanks
thanks

I don't recall the specific figures.

The difference is only the thickness of this layer and it is interesting for the area of direct heat transfer. Here i expect better results with not anodized surfaces.
The other parts of the cooler, in contact with air(?), might have even an advantage if anodized. The alumina increases the "active area" of the surface due to the porosity - one reason that you get the higher emissivity of IR and maybe a better convection, too. The better mechanical properties of the anodized surface should be known.
Keep in mind that copper is mostly used in high performance thermal systems.
