More Than Complex Mold Aluminum Heat Sink For Led Lighting With CNC Machining

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 is the most effective heat sink?

Copper is one of the best materials to choose for heat sinks as it has a high thermal conductivity. But aluminum is most commonly used due to it's lower cost and relatively high thermal conductivity.

A custom heatsink is a good choice for the for the most challenging applications. In the simplest form, Fodor can use one of our wide range of standard heatsinks, and then modify to meet the thermal application requirements. Customizing a standard heatsink helps reduce a heatsink cost, and also can reduce the prototype time dramatically. For larger heatsinks, we can also look an existing extrusion before it has been cut for a standard heatsink. Where a standard heatsink can not be modified, our engineering team will then design a custom heatsink solution using the most appropriate manufacturing process.

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

The heat sinks can further be classified by their physical designs and shapes, material used and more. Typical heat sinks are:

• Stamped
• Machining
• Bonded-fin
• Folded-fin
• Forged Heat Sinks
• Single Fin Assembly Heat Sinks
• Swaged Heat Sinks
• Skived Heat Sinks

Notes

What does an aluminum heat sink do?
An Aluminum heatsink is an excellent conductor of heat. Although the thermal properties are less than copper, An aluminum heatsink weighs approximately half as much as a copper conductor having the same conductivity, and is also less expensive.

What are the disadvantages of aluminium heat sink?
Disadvantages of heat sink made with aluminium
Aluminium is not suitable for high-power equipment where heat conductivity is more important than weight-saving. To dissipate heat faster than 95W, copper heat sink is preferred to aluminium heat sink. For example, gaming computers generate lots of heat.

Is ceramic or aluminum better for heat sink?
Even though the thermal resistance of the Ceramic is much higher than Aluminium because of the micro porous structure it provides excellent heat dissipation and heat convection. It also provides low thermal capacity in unit volume compared to Copper and Aluminium Heat Sinks.

What is the cheapest heat sink material?
aluminum alloy
The most affordable heat sinks are generally made ofaluminum alloy. Copper heat sinks offer excellent thermal conductivity — it is twice as conductive as aluminum — as well as corrosion resistance, antimicrobial resistance, and other desirable properties
