which type of redaitors are the best?
I found a new 35X37 cm redaitor made of Copper for 61$
is copper good or there is better material?

 

copper is old school. its a good heat radiator, aluminum is better. aluminum is the new way. if you need a civic radiator, i have one from my vx in great condition. the insides are super clean. pm me if you are interested. 28mm hose fittings, if you have a swap, you need 32mm

 

dont waste your time with copper radiators ... just buy a csf or koyo aluminum oem radiator ... they are plastic tanks with aluminum cores and they usually go for about 100-125 i sell them for the civics for 100 picked up brand new

 

Koyo or Fluidyne

 

del sol dual core

 

WACK

 

Why the aluminum is better than the copper?

 

copper costs wayyyy more than aluminum

but which one is better?

 

just get the aluminum one made for your vehicle, it will work for all of your needs, there are cars with 700whp and they dont have any issues with an aluminum radiator.

 

Aluminum dissapates heat faster..

INCORRECT. copper dissipates heat fast, if the given area is the same. the main reason many of today's automobile have radiators made from aluminum is primarily cost. alum is cheaper then copper.

but, to answer the question whether alum is good enough, yes it is. i run alum, as many many people do with no ill results. a big plus for me is the alum, is much lighter then it's equally sized copper counterpart.

this is very intresting but i would like to know where your getting yourinformation because everything i have read always said that a 2 core copper radiator cant displace the heat a 1 core aluminum radiator can ... when i have time tonight i will look this up but for no i gotta go to work

 

you are welcome to research it. given equal design, copper is ultimately better at dissipating heat, although is heavier and costs more. do a simple google search, as this information is readily available.

BUT, i do agree that alum radiators are far more econimical/better for our cars. i just wanted to clear up some misinformation.

*edit- did that aforementioned google search and found a few references, one of them being http://www.autofieldguide.com/articles/040304.html

im a computer nerd and here is how it works with heatsinks. Aluminum heatsinks, get the job done, cheaper. Copper heatsinks, better heat absorbtion a little more expensive.

my computer had an aluminum heatsink, and i bought a copper heatsink of the same size, the thing was heavier than the aluminum and more expensive BUT, my CPU ran 4°C cooler with the copper than the aluminum heatsink.

so basically, the aluminum one gets the job done, but the copper is better at absorbing heat, as well as your wallet and adding weight

as far as the OP question,

i would go with aluminum for weight savings, aluminum will get the job done, and is cheaper as well

 

copper (0.385 J/g) has a lower specific heat than aluminum (0.902 J/g), allowing it to dissipate heat faster and more efficiently since it can absorb heat more readily. There is no denying this fact. Copper however is more expensive and IMO overkill in pretty much all applications we will see here.

 

yes this is true. copper dissipates heat faster. which is why a lotta heatsinks for computers are copper =P

there was a good writeup somewhere on google, go find it.
