1. What is a heatsink profile?
A heatsink profile is usually an extrusion piece or can be formed from other methods to help remove heat from devices or equipment.
There will generally be a base and fins on the heatsink profile.
The base is where heat is introduced to the heatsink.
While the fins are used to expand the surface area for cooling.
So when using a heatsink profile you are able to expand your cooling efficiency while taking up less space.
Most heatsink profiles are made out of aluminum due to its ability to be extruded into many different shapes.
You can have many different variations of extruded shapes.
From straight fins to pins and even curves. You can also add grooves or even brackets into your heatsink profile.
Check out our 【Heatsink Extrusion Profiles】 and 【Heat Sink Extrusion】 page to learn more.
2. How does a heatsink profile work?
A heatsink profile allows heat to be transferred in different ways.
When a device introduces heat to a heatsink profile the heat will be dispersed through the base of the heatsink.
Then the heat will travel to the fins which then transfer the heat away from the heatsink.
Depending on the shape of your profile can allow you to transfer heat faster or slower.
For instance having taller fins will allow you to dissipate heat at a greater rate.
But if you fins are too tall it can hinder your air flow which can slow down your cooling process.
By adding forced air to your heatsink profile you can improve cooling rates even more.
You can also use natural convection if your heat output isn’t as high.
It all depends on your situation.
3. Types of Heatsink Profiles
There are many different types of heatsink profiles that can be used for your applications.
3.1 Straight Fin Heatsink Profiles
Straight fins are a great way to cool your equipment.
They are a simple design that can be extruded very easily.
These are commonly found in industrial applications and electronics.
3.2 Pin Fin Heatsink Profiles
Pin fin heatsink profiles can consist of pins that are round or any other shape.
By using pin fins you are able to dissipate heat from all directions.
Which is beneficial if your air flow can change directions.
3.3 Skived Fin Heatsink Profiles
Skived fins are produced from a block of metal.
They can be made with thinner fins and closer together to give you more surface area.
Check out our 【Skived Fin Heat Sink】 to learn more.
3.4 Extruded Heatsink Profiles
Extruded heatsink profiles can be used for many applications.
They can be created to almost any shape you want.
Which makes them one of the most used methods when producing heatsinks.
Check out our 【Extruded Heat Sink】 to learn more.
3.5 Zipper Fin Heatsink Profiles
Zipper fin heatsink profiles can be used to get more surface area in a smaller space.
They are a very thin fin that can be packed tight together.
Learn more about our 【Zipper Fin Heat Sink】.
3.6 Bonded Fin Heatsink Profiles
Bonded fin heatsink profiles can allow you to create any dimension of fin you want.
By bonding the fins to your base you are not restricted by an extrusion die.
Check out our 【Bonded Fin Heat Sink】 to learn more.
3.7 Heat Pipe Heatsink Profiles
You can also add heat pipes to your heatsink profile.
Heat pipes can transfer heat to certain areas of your heatsink.
This can be useful if you have one area that produces more heat than others.
Check out our 【Heat Pipe Heat Sink】 to learn more.
4. Materials Used In Heatsink Profiles
When selecting what material to use for your heatsink profile there are many factors to consider.
4.1 Aluminum
As stated earlier most heatsink profiles are made out of aluminum.
There are many benefits to using aluminum:
- Great conductivity
- Lightweight
- Corrosion resistant
- Can be extruded easily
- Affordable
- Can be machined easily
There are many types of aluminum that can be used to make your heatsink profile.
Each have their own pros and cons.
Learn more about our 【Aluminium Heat Sink Material】.
4.2 Copper

Copper is a great conductor of heat but it is heavier than aluminum.
And can be difficult to extrude or form into certain shapes.
Learn more about our 【Copper Heatsinks】.
4.3 Copper Aluminum
You can also use both copper and aluminum to make your heatsinks.
This will allow you to use copper where you need more conductivity and aluminum for lighter areas.

5. Design Considerations For Heatsink Profiles
There are many things to think about when designing your heatsink profile.
5.1 Base Thickness
How thick your base is will depend on how much heat you are trying to dissipate.
Thicker base will spread heat out over a wider area but will take more material.
So make sure your base is optimized for your needs.
5.2 Fin Height
Your fins can be as tall as you want but you want to make sure that they don’t obstruct your air flow.
Make sure your fin height is optimized for your cooling method.
5.3 Fin Thickness
Your fin thickness can be as thin as you want.
But you will want to make sure they are easy to manufacture and will not bend.
5.4 Fin Spacing
How far apart your fins are will also affect your cooling.
Having fins that are closer together will allow you to have more fins but could restrict your air flow.
You will want to find a happy medium that will work for your situation.
5.5 Length
You can make your heatsink profiles as long as you want when they are being extruded.
Then cut them to your desired length.
So you can design your profile to fit your needs.
5.6 Mounting
You can also add features to your profile to allow for mounting.
Such as grooves for screws or other brackets.
6. How To Make A Heatsink Profile
When making a heatsink profile you can use an aluminum extrusion process to make your heatsinks.
Here is a list of steps that are involved in the extrusion process.
l Design Your Heatsink Profile
You will first want to design the shape you want for your heatsink profile.
Keep in mind that there are certain restrictions when it comes to extrusion.
l Create Extrusion Die
Once you have your heatsink profile designed you will need to create a die to extrude with.
Your die will determine what shape your heatsink profile will be.
Make sure to keep your fin design in mind when creating your die.
l Heat Your Billet
You will want to heat your aluminum to a certain temperature to allow it to be extruded.
l Extrude
Your aluminum will be pushed through the die to create your heatsink profile.
l Cool
After your aluminum has been extruded you will want to cool it down.
Make sure to cool it properly so it doesn’t deform.
l Straighten
Sometimes after extrusion your heatsink profile will need to be straightened.
l Cut
Once your heatsink profile has cooled and straightened you will want to cut it to your desired length.
You can use a automatic cutting machine to cut your heatsink profiles.
l CNC Machine
If you want to add any extra features to your heatsink profile you can use CNC machining to add those features.
l Surface Treatments
Once your heatsink profile has been cut and machined you can apply surface treatments to your heatsink.
l Inspect
You will want to make sure your heatsink profile meets your specifications.
You can measure:
- Dimensions
- Fin Thickness
- Spacing
- Flatness
- Surface Quality
- Mounting
