Improved Thermal Management of Telecommunications Cabinets using Surface Treatments
Keywords: telecommunications OSP, thermal emittance, solar reflectance
TAG Technology is a coating product that selectively increases the infrared reflectance and thermal emittance (TE) of a surface. Independent testing has shown the ability to reduce incident eergy absorbtion by 15% compared to an ultra-bright white surface and increase the TE by 7% compared to a a black surface. TAG can be used in colored coatings and is less sensitive to dust than paints. Once of the most interesting applications for TAG is in exterior enclosures subject to both solar heat loads and internally generated heat from electronics. The use of TAG on the exterior surface or heat sinks can be enough to achieve a 3-7C reduction in internal temperature. These reductions may enable the designer to use passive cooling, eliminate solar shields, use steel rather than aluminum enclosures, or create more compact designs. This presentation will describe independent tests and case study data.
