Every type of heat sink manufacturing process contains its benefits and flaws.
Besides, there are several ways you can manufacture large aluminum heat sinks.
Here are some common types of large aluminum heat sinks:
Extruded Large Aluminum Heat Sink
Extruded aluminum heat sink
Most heat sinks are commonly made from extruded aluminum heat sinks.
Besides, this process is vital for several applications.
Extruded large aluminum heat sinks are cost-effective and you can easily customize the specifications.
Also, the performance of extruded large aluminum heat sinks can range from high to low.
However, the limitation of these heat sinks is that you are limited by the dimension.
This is because there is a limit to the maximum width of the extrusion.
Bonded Large Aluminum Heat Sink
Bonded finned aluminum heat sink
These types of aluminum heat sinks are popular in applications requiring large-sized heat sinks.
Bonded aluminum heat sinks have the advantage of having different materials for the base and the fin.
Besides, you can use both aluminum fins and copper fins instead of using a single material for the fins.
This will enable you to enhance the thermal performance of the large aluminum heat sink.
Also, you will only add a small amount of weight to the entire system.
However, the bonded large aluminum heat sink will provide moderate performance and they are costly.
Skived Large Aluminum Heat Sink
The heat sinks that you will make using this method normally use copper.
Skived aluminum heat sink comes from a solid block of aluminum metal.
Besides, this type of large aluminum heat sink will provide more flexibility in the design process.
Also, it allows you to achieve a high fin density that forms a high surface area for more heat to dissipate.
The performance of skived large aluminum heat sink ranges from medium to high.
They have the limitation of having more weigh and directional sensitivity.

Stamped Large Aluminum Heat Sink
Stamped aluminum heat sink
When you use this process, you will stamp the metal fins of large aluminum heat sinks then solder them to a base.
This type of large aluminum heat sink is suitable for low-power usages.
The stamped large aluminum heat sink has the benefit of being cost-effective since the production is automatic.
However, they have the limitation of providing low performance.
Forged Large Aluminum Heat Sink
Forged aluminum heat sink
This type of large aluminum heat sink comes about by compressing aluminum material.
The forged aluminum heat sink has several applications.
Besides, you can choose to either hot forge or cold forge this heat sink.
Also, they will provide a minimum level of performance, and you can manufacture them in high volumes at low costs.
However, a forged large aluminum heat sink will provide minimal design capabilities.
CNC Machined Large Aluminum Heat Sink
CNC machined aluminum heat sink
This type of large aluminum heat sink will provide high thermal conductivity.
It also enables you to design complex geometries using this process.
This allows you to have several flexibility options within your design.
However, they are costly to produce and it takes a lot of time to produce every piece.
This makes it not suitable when making high volumes of CNC machined large aluminum heat sinks.
Die Cast Large Aluminum Heat Sink
This type of large aluminum heat sink comes through the process of die-casting.
Besides, the production efficiency of this process is high, making it suitable to produce high volumes.
Also, die cast aluminum heat sink has a high heat dissipation effect and is cost-effective.

Pin Fin Large Aluminum Heat Sink
Pin fin aluminum heat sink is produced through the process of cold forging.
They are also known as cold forging large aluminum heat sinks.
Besides, the cost of conducting cold forging is not high, making the production process cost-effective.
