When it comes to cooling electronic components, heat sinks are one of the most important tools at your disposal. And when it comes to heat sinks, there are two main types: stacked fin and folded fin.

The stacked fin heat sink is made by using high pressure to press a special structure single profile and multiple profiles together into a complete heat sink. The stacked fin heat sink is often used in machines that need heat dissipation from both sides. From the appearance, both sides are the cooling base plate, the heat sink fins in the middle, and heat from both sides through the cooling base plate to the central fins for heat dissipation.

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. This helps to create more surface area for dissipating heat, making it a better option for larger components.

There are several key differences between stacked fin heat sinks and folded fin heat sinks.

1. Number of fins;

Stacked fin heat sinks are typically taller and narrower than folded fin heat sinks, and they have more fins per unit area. This allows them to dissipate heat more efficiently.

Folded fin heat sinks are wider and shorter than stacked fin heat sinks, and they have fewer fins per unit area. This makes them less efficient but also allows them to take up less space.

2. Applicable fields;

Stacked fin heat sinks are best for high-performance applications, as they can dissipate a lot of heat.

Folded fin heat sinks are best for low-power applications, as they can prevent the formation of air pockets.

3. Price;

Stacked fin heat sinks are typically cheaper and easier to manufacture than folded fin heat sinks.

Ultimately, the best choice for you depends on your device and its needs. If you need a heat sink that can handle a lot of heat, then you should choose a stacked fin heat sink. If you need a heat sink that is small and lightweight, then you should choose a folded fin heat sink.
