if air goes throught a lot of tiny aluminum will cause cooling? Why am i asking this because when you see inside the computer desktop has heatsink fan, and some of the heatsink are made by aluminum.
The aluminium heatsink absorbs the heat from the component it is connected to, the heatsink will have a very large surface area-to-volume and the heat will pass into the air due to this. so you can see its not actualy the metal that causes cooling, the metal just transfers the heat to the air where it will be taken away by fans etc.
aluminum is a full conductive metal that gathers the heat from the other sides of the computer and when the wind passes the aluminum, It will cool down and gather the heat again and again.That's why some computers have aluminum made heat sink.Also some of them have copper heat sink that is better conductor than aluminum
Yes, aluminum is a great heat dissipater and is the primary material used for almost any heatsink.
Aluminium doesn't 'cause' cooling, but it is efficient at dissipating heat. Copper is too, which is why both metals are often used to make heatsinks.
Sorry, but copper is just the opposite of aluminum. It soaks up heat like a sponge and doesn't dissipate it quickly. Try heating a piece of copper tubing and see how long it takes before you can touch it.
