Coating that is both reflective and thermally conductive

[artengn]

I have an electrical enclosure that sits in direct sunlight and must use passive cooling. Does anyone know of or have ideas on where to find information about a finish for aluminum (380A) that is both reflective of sun radiation while allowing thermal energy generated within the enclosure to efficiently pass through for convective cooling?

Googling "IR reflective coating" nets quite a few results. ZEFFLE made by Daikin is one. Just find one with a low heat transfer coefficient.

Though, I would find a more durable solution - maybe have a sheet/s of Al on stand-offs to shade the enclosure. probably cheaper and definitely more effective and hard wearing than a high tech paint. They could also double as weather proofing for air vents.
