The heat radiates from the surface of a heat sink, so the greater the surface area, the better the heatsink. Roughly speaking, if you cut a load of slots in your big block of aluminium, you could end up with, say, 5 times the surface area, and the heatsink can then get rid of 5 times the heat.

Have a read of the Wikipedia article - the big block is, in general, rather poor compared to the fins.
Heat sinks are used in CPUs and graphics processors. They’re found in everything from lighting equipment to automotive equipment.
When you’re designing a heat sink, there are compromises you need to make.

You need to find the right balance between factors that affect performance. Keep in mind that performance can be affected by things like:
When it comes to material choice, aluminum is the most common. It’s also worth noting that the most common manufacturing process for heat sinks is extrusion.
Let’s talk about why you might choose aluminum over copper (another common choice). And then we’ll talk about the most appropriate alloys you might choose from.
We’ve talked before about the benefits of both aluminum and copper in heat sinks.
