Feb 16, 2008It's easy for me to understand why a black surface absorbs heat. Simply said, because it doesn't reflect incoming radiation. But it's very hard for me visualize why a heat-sink, for a power transistor for instance, dissipates better if anodized black. How does the internal heat within the heat-sink "sees" the black external surface? Can anodized heat sinks be dyed?Can anodized heat sinks be dyed?Anodized heat sinks can be dyed in colors like blue, green, black, and so on. It is important to note, however, that the only real impact of color is a visual one. Regardless of the color, heat transfer will not be affected.Anodized Aluminum Heatsinks What You Need to Know - Gabrian What are the benefits of Anodizing aluminum extrusions?What are the benefits of Anodizing aluminum extrusions?Your extrusions are placed in an electrolytic bath. A low-voltage, high-amperage direct current passes through them. The oxide layer thickens and a porous surface develops. Thickening the oxide layer has its benefits. What are the Benefits of Anodizing Heat Sinks? There are a number of general benefits to anodizing aluminum extrusions.Anodized Aluminum Heatsinks What You Need to Know - Gabrian

This extruded heat sink is designed for power modules and IGBTs and features 101 x 139mm base mounting area with 6 mounting holes.Anodized Aluminum Heatsinks What You Need to KnowBlack Anodized Aluminum Heatsink Emissivity improves as a result of its microscopic texturing and increased surface area. The unfinished surface of aluminum can be measured at an emissivity of approximately 0.05. The emissivity of an anodized aluminum surface can be measured at around 0.85.
Anodized heat sink can be dyed in colors like black, blue, green, and so on. It is important to note, however, that the only real impact of color is a visual one. Regardless of the color, heat transfer will not be affected. The clear anodized surface has the same emission characteristics as the black anodized Black Anodized Extruded Aluminum Heatsink Extrusion black anodized heatsinkBlack Anodized Extruded Aluminum Heatsink Extrusion Housing Aluminum extrusions are cost-effective solutions for the majority of electronic cooling applications. Extrusion profiles enable engineers to either select or start their design from a pre-tooled extrusion profile for the cooling solution.Black anodized heat-sinks, why do they disipate heat black anodized heatsinkFeb 16, 2008It's easy for me to understand why a black surface absorbs heat.

imagesThe performance of a heatsink with a black surface - Page 1Jun 20, 2011Black heat sinks are normally anodized black. This is an electrochemical process that builds a very thin (several micrometers) of aluminum oxide (which is clear). The initial anodization produces a porous surface structure.Kx32 Ultimate Heatsink Kit for the Elecraft KX3 - Pro black anodized heatsinkThe other reason PAE employs a Type III hard coat anodize on our heatsinks is to render the heatsinks far more resistant to damage, since a Type III anodized surface has a hardness of 60-70 on the Rockwell C scale. 2) I have a new KX3 with the stock Elecraft enhanced heatsink.
