This aluminum profile housing heat sink is based aluminum profile 6063-T5 material to processing, first of all, we check the raw material dimension is fine or not, the second is that according to the drawing, cutting right length, the third is that accroding to the drawing, use the wood machine to cut the outline dimension, the forth is that use the CNC to do exact dimension, the fifth is do anodizing clear, the last step is riveting, and then inspection/packing. First inspection and patrol inspection are done in processing .

What are the Benefits of Anodizing Heat Sinks?
There are a number of general benefits to anodizing aluminum extrusions. Some of the key benefits of anodized heat sinks are:
Corrosion resistance, wear resistance, and electrical isolation improve because of the thickness of the oxide layer.
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.
This is a significant difference. But the improved radiation heat transfer will have a more pronounced effect (percentage-wise) on heat sinks that are smaller. It will also have less overall impact on active heat sinks (which utilize a fan).
Anodized Aluminum Heatsinks: What You Need to Know
Heat sinks play an important role in electronic and mechanical devices. They act as passive heat exchangers, transferring heat from hot components to a fluid medium (usually air).
There are different types of heat sinks. Some are made from copper and some are made from aluminum. But, most commonly, heatsinks are made through the process of aluminum extrusion. And those extruded heat sinks are also commonly anodized.
Why is this the case? What benefits does anodization offer? Let’s first talk about how anodization works and then the benefits it offers.
Does Color Impact Heat Sink Performance?
Another benefit to anodizing aluminum extrusions is the ability to add colored dyes.
The porous oxide layer can be filled with dye that gets locked in and is resistant to fading.
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.
Metals with excellent thermal conductivity such as diamond, copper and aluminum make the most efficient heat sinks. However aluminum is more commonly used due to its lower costs.
Other factors that affect a heat sink’s performance include:
Heat sinks are used to cool various electronics components whose heat dissipation abilities are is insufficient to dissipate all the excess heat. These devices include:
