- miahi 5mo agoNot really. They use aluminum fins because they are way lighter and cheaper. The copper tubes are actually heat pipes that transfer the heat through liquid/vapor phase change. And copper is used because the liquid inside is water (aluminum would corrode) and they are also easier to bend into shape (aluminum fatigues easier with bends, and pores would allow the liquid to escape).
- vitally3643 4mo agoThe capacity of an object to radiate heat has essentially nothing to do with material properties. The equation is entirely dominated by surface area and nothing else. It is purely a matter of geometry. Which is why we use aluminum: it's cheaper and its lower thermal conductivity is pretty much irrelevant.
