using car radiators...why not?

[Alexontherocks]

I tried lokking around for the answer to my question but I did not get conclusive results...

I may have found a used iwaki (very lucky) so I am currently thinking big..I am intrigued by car radiators. If flow and head is not a problem why should I stick to conventional computer parts and not go for this: http://cgi.ebay.it/Radiatore-motore-...QQcmdZViewItem

looks big and it is completely made of alluminium. I guess that even passive operation is achievable if the flow is just right...

I have been looking for specific details on the exact heat dissipation capacity of this radiator as well as others but have found nothing....how many watts could an iwaki rd30 + a car radiator (let us take the one I posted a link to) dissipate?

Cheers!

There was someone on these forums that has done that with a Copper Race Radiator from a Japanese company. His delta between temps is insane, and is able to handle his entire rig passive without a problem.

I don't know if you have been following the corrosion / mixed metal wars here, but if you are mixing Al and copper in a loop IMO there is a relativly high risk of corrosion.

Yeah aluminum and copper is no good. I was thinking of using car rad, but when I saw that it's made of aluminum I changed my mind.
Then I got an air conditioner from a car, pulled the radiator from there, that's the good stuff! All copper tubing, and very big too, my water temps were the same whether with fans or not..

[Alexontherocks]

I understand......

are all AC units from cars made in copper? I may very well be able to get hold of a very good one.

an EVAP from a car will be full of oil unless you mean a H/C? also MOST if not all A/C components are ALU

[Alexontherocks]

sorry guys what do you think of this pump? sorry for the off topic but I was just curious to know if something like this could be suited to run such a performing loop:

[Alexontherocks]

no one? I could get hold of an iwaki or this.....I am unsure because the head (HM) is 10 which is very good and the flow is actually better than an iwaki.

[STEvil]

You only gave 50 minutes for an answer. I cant read the name of the pump you've pictured so cant look it up on the net. Couldn't say.

Madmaxx - I think Jackies is thinking of the heatercore which is used to heat the interior of the vehicle.

Dont get that radiator, it's aluminum. See BrokenWall's post if you want to do it right.

[Fraggle]

I think that pump looks way overkill.

[Alexontherocks]

I ask forgiveness for my impatience.....

Anyway the pump is overkill. I will get this one since it has 10m of head pressure and 8400 l/hour of flow !!!

Regarding the aluminium radiator....couldn't anticorrosives do the trick? I can get hold of various chemicals from a friend who works at a lab. I read that phosphates help a lot so I could try those.

It is very difficult to find copper radiators since they are heavy and serve no purpose on cars really (that aluminium can not serve as well and in a cheaper way)

My loop would consist of ek supreme - super pump (should be a univer) - and car radiator.

Isn't there anyway I can get aluminium and copper to work together?

thanks!

anticorrosives could do the trick but you would need a large amount of them in your water. That would hinder performance as well, as compared to distilled water.. i would look for a copper one if i were you

[aspire.comptech]

Yes and no, mixing copper and aluminum can never be completely safe.

However the main reason not to do it is because glycol is quite inferior to water as a coolant.

[003]

yeah, anti-corrosives are typically dissolved solids, which just end up precipitating in your loop, and lower performance. You would need a lot for that huge radiator. Not worth it, find a copper /brass one.

[madmaxx]

arent phosphates hazardous to the enviroment?

[DarthBeavis]

using car radiators...why not? ? Because the mighty mighty XS forum members said no.

Nothing wrong with car radiators, just aluminum ones.

Probably a bit UGLY . . .unless you get one from one of Jay Leno's hot rods . . .

Like we want to mimick them . . .look at the pathetic fuel efficiency standards . . .if the computer industry was like the auto industry we would have 286's running on 4000k PSUS . . .

True

Thats because you use antifreeze which is an anti-corrosive agent.

Now in your car, you aren't looking for superb temps as they have a much higher tolerance of heat. For a car 80C is nothing but for liquid cooling you'd be shatting yourself.

[sirheck]

I use anti-freeze in my computers watercooling sys.
