Black Anodizing Aluminum Profile Heat Sink With Surface Treatment

Black Anodizing Heat Sink Aluminum Extrusion Profiles With Surface Treatment Anodizing Black

DONGGUAN FODOR TECHNOLOGY COMAPNY PROFILE-2021(1)....

Quick Detail

Description

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:

• Improved Corrosion Resistance
• Improved Wear Resistance
• Increased Electrical Isolation
• Improved Surface Emissivity

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.

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:

1. Thermal Resistance
2. Airflow
3. Volumetric resistance
4. Fin density
5. Fin spacing
6. Width
7. Length

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:

• Power transistors, thyristors and other switching devices
• Diodes
• Integrated circuits
• CPU Processors
• Graphic processors
• LEDs
