Uh Oh brass heatercore!

shuRe · 05-23-2005, 02:09 PM

stupidly didnt ask the guy i brought this off if it was brass or copper and i ended up with a brass one

Its a bonneville 77 with a/c (2x120) apart from being a bit harder to remove the fittings, how much will this effect my temps comapired to a copper one?

No effect on temps.

Brass is commonly used, at least for the tanks.

I just polished and clear coated mine last weekend.

cheers m8, no one else seems to know

Yeah, the brass is so thin the difference won't be measurable probably.

LOL...this almost sounds like a myth for the Myth Busters to test. It would be interesting to watch what they would come up with!

Do you think it's a myth? (that the rad channel wall is so thin it's thickness is insignificant?)

They are almost all brass. Can be made much thinner and cheaper than copper. And we all know thinner is better for cooling.

To answer your question I will quote myself...

I just ment it would be funny to watch the Myth Busters come up with some fancy way to test this subject. And who knows...they may decide it would be fun to just blow the whole thing up (which they usually do

)

They're brass to be strong as car engine bays are rough places.
Ideally, we'd be using copper foil or 0.1mm copper sheet tubes as we don't give a toss about strength.
However, I imagine economies of scale put truly custom heater cores waaay out there.

Then again, I recall Marci @ thermochill saying he makes everything in house?

Bare in mind also that a good size heater core (120.2, 120.3, PA160) under "good" air flow has a delta-T between air and water of like 2 to 3 degrees.
The theoretical limit due to using air is upwards of 1.5 degrees.

Not a lot to gain even if they retooled (if its possible).

Oh, and most tubes are coated in a mega-thin layer of solder to be able to construct them too...

I would also observe that if you could make one out of glass you would probably not notice any difference. Plastic might be a bit more significant, depending on the type...
