im thinking of building my own Radiator.
so the thing is how do i calculate how much heat can a Radiators handle

so that i dont make it too small

Well that is actually harder that you may think. The cooling power of the radiator depends on so many things that its pretty darn to calculate. You may get some idea on how much heat it could dispel, but getting anywhere near the real value is hard. I'd really just look at the construction of radiators that are on sale and make something like that if possible. The Innovatek passive-radiator segments are something that you could look at.

well if we simplify the calculation a lot then ?

how much can a sheet of copper evaporate heat

lets just think that the heat magically transports to the coppe from the heat sourse

Well it doesn't. There exists something called thermal resistance which always comes into play. This is why you would need a thermal compound on eg. a CPU.

Just thinking that there is no thermal resistance would nullify all calculations made. Of course if you just want an estimate and wildly overdo the actual radiator go ahead.

It's been some time since calculating these in school, but I'd say you would need the heat transfer coefficient of copper/square meter and keep going from that.

And no I am not doing the calculations for you ;)
