Heat Transfer Coefficient of coatings?
Heat Transfer Coefficient of coatings?
(OP)
Hi All
I have an application, with mostly aluminum parts. I have a central block that is water cooled. I have exterior parts that are bolted to the central block. I do not want to impede the heat transfer from the outside block to the inside cooling block. However, I would like to plate the parts so that I can increase reflectivity. I want to reflect as much heat as possible. This is a welding head, so close proximity to the heat source.
I was going to use an electroles Nickel coating for reflectivity but I haven't been able to find any info on thermal conductivity? I want to make sure I don't insulate the mating surfaces. I would have to mask the plating if the plating hurts the transfer.
Any suggestions or comments appreciated.

Here is a another coating from Alumiplate that may meet your requirements. We used this as a front surface mirror in the near infra-red and few other things.
I would give them a call to get specific data for your requirements.

The reason for plating is heat reflection and easy surface cleanup. I keep going back and forth with the tradeoff of heat transfer with the plating. Any thoughts?
