How Folded Fin Heat Sinks Provide Better Cooling

You might not have heard of folded fin heat sinks before, but they're a great way to improve the cooling performance of your products. In this article, we'll take a closer look at folded fin heat sinks.


A Folded Fin Heat Sinks is one continuous thin sheet of aluminum or copper folded to allow it to be soldered or epoxy bonded to a custom machined base.


Manufacturing process of folded fin heat sinks

Folded fins are created by a progressive stamping method. The fins are then bonded to a base with thermally conductive epoxy, brazing, welding, or similar metallurgical bonds, to create a heat sink. An advantage of folded fin heat sinks is the ability to combine aluminum and copper to tailor the performance of the heat sink to the particular application.

What are the advantages of folded fin heat sinks?

1.The folded fins create more surface area for the heat to dissipate, which means that your device can cool down faster. They're also really efficient at transferring heat away from your device, so it stays nice and cool.

2. They're really easy to install, and they take up minimal space. So if you're looking for a way to improve the cooling on your device, then you should consider using folded fin heat sinks.

3.Folded fin heat sinks help improve the airflow around them, which helps cool them down and prevents them from overheating. 

4.Folded fin heat sinks are less expensive to manufacture than traditional heat sinks, which makes them a more cost-effective option.


There are a few things to consider when shopping for folded fin heat sinks. The most important is the size and shape of the fins. You want to find fins that are as close to the shape of your component as possible so that the greatest surface area is in contact with the air.

You'll also want to make sure that the fins are spaced evenly apart so that there's plenty of airflow through them. And finally, you'll want to choose a heat sink that's made of a good quality material, like aluminium or copper.
