Making a Heate core

saton472 · 02-10-2003, 02:52 PM

Hey People I want to make my own heatcore for my system and i was wondering if anyone could give me some tips and trickes :shrug:

airspirit · 02-10-2003, 08:34 PM

Tip: buy one. It is cheaper. If you are looking to be really cheap, go to a scrapyard. It is hard to make an effective heatercore for cheap. You can buy some new for under $30.

If you want to MAKE one, get some thickwall copper tubing and make a big ass grid out of it for the water to flow through and mount it on your wall (there is a picture of one of these being used passively somewhere in here).

saton472 · 02-10-2003, 09:21 PM

I want to make one that will fit on the outside of the side the mobo is on. youj thinking why the h$## does he want to build one for. the reason is because that way i can say "Hey everybody look what I did isn't it great." And then have everybody

or go

so i can go

you could do something like that. Its not exactly a heatercore, but it looks easy enough. You could mod the idea a bit to make it more effective.

Make a trip down to a radiator shop ..They can make you one up to any size and shape you want

saton472 · 02-11-2003, 11:05 AM

Hey Jack. thanks for the url, but im tending to go with a rectangular one

saton472 · 02-19-2003, 11:56 AM

Iv decided to make my own radiator. I just need some help with the spacing of the fins.if anyd body has some ideas on what the proper spacing of the fins is please tell me.

Also im going to use copper tubing so would there be any problem with using allumminem for the fins. im asking because iv heard a lot about the "battery effect". if any one knows what this is please explain it.

The battery effect only occurs when dissimilar metals are both in contact with the same pool of water. Having aluminum fins on the outside of your copper pipes will not result in the aluminum being in contact with the water (unless you spring a leak!

).

The problem you are going to face is attaching the aluminum to the copper efficiently (thermally speaking). I don't believe you can solder Al to Cu. I could be wrong....

..........to boldly go where no/few have gone before."

Well I'd buy one, I'm picking one up when I go into town in half an hour, $32 new for one 9.5" X 6.125" X 2" #2-243 in the Fedco lists. There is one that is perhaps large enough for what you want it's like 12" X 8" X 2" which is huge for a heater core.

I had to point that out as it would save a heck of a lot of work. But to answer your questions.

Aluminum fins on copper tubeing would be fine. Copper is however a better cooling agent for fins than alum. just harder to work with, much like with blocks. Depending on the heater core of radiator the fin count can run anywhere from 12 to as high as 24 from what I've read. More is better, Cathar used a core that had 22 or 24 per inch in his Big Arse rads he was making at one time. But CAthar was building a shroud onto a heater core he had bought. Problem is knowing the fin count before you buy, although that won't be a problem for you. If you can find oval shaped tubes that are 1/2 to 5/8" by 1/8 to 3/16" wide like those used in some rads at a custom shop I'd suggest you buy some of that tubing as the cooling would be far better than round tubes. Or if you could figure a way to flatten small round tubes down uniformly that would also work. But I have no idea where to get this done or to buy the flat tubes. I also have no good idea how you'll make the tanks, 2" cu pipe at each end with cuts holes for all the small tubes? A massive soldering job as well. This is about all I can think of in regards to making your own rad.

A long serpentine series of passes of a single tube in a rad the size of even a mini case will I'm sorry to say kill off your pumps flow. You could real quick have 25 ft. of 1/2" tubing and perhaps much more. Even the best pumps will be brought to their knees by that many feet of tube with so many 180 degree bends. So while tempting for ease of build don't go down this road. This is also why oil coolers faded from use fast, poor cooling for the restriction imposed.

Battery effect is from aluminum and copper in the same system in contact with the water. Strange as it may seem the water pulls off molecules of copper and Aluminum when contacting both in the system although anodizing of the Alum. and anti-corrosive additives in the water can pretty well stop this. This will turn your water dark, that is your warning.

There are a few custom rad makers that can make any rad you wish, but they are expensive. Still think the best idea is buy, not build. But hope these answers are of some help. If your project comes out well, and I hope it will, how about posting some picks.

Tranny coolers use copper tubing and AL fins. They just use pressure for the bond. I would just solder on some Copper fins though. Or maybe even thermal epoxy like Arctic Silver Epoxy?

Blackeagle · 02-19-2003, 11:03 PM

Interesting idea Jaydee116, I hadn't thought about glueing for connecting the fins. JB weld might be another good choice for that.

I still think the hardest part would be the tanks and connecting them to the small tubes.

saton472 · 02-20-2003, 02:40 PM

Thankes for the advice. I really dont know what ill have in the system or what room ill have in the case ( i havent orderd it yet but you might b able to figure it out your self.:shrug: :shrug: here is the site. http://www.tigerdirect.com/applicati...?sku=C255-1006

I was pllaning on making something like this http://www.dangerden.com/mall/radiators_old.asp

sorry about the spelling and stuff i have the flu and dont know what im typing

Gulp35 · 02-21-2003, 11:04 PM

you could do some thing like this http://www.overclockers.com/tips857/

Looks promising and you could stack multaples of these to get greater surface area.

I did a rough calc of the surface area of the chevette HC and got ~864in^2, If i was to make one of these that would cover the side of my case It would have 604 in^2 so I was thinking of making a second one and stacking it. Plus you could stack alot and only require minimal fans. Only bad thing is that you would need a stronger pump to push the water.

It would be a shame to buy that pretty case with a window in to show off an ugly radiator or heater core. May I suggest something mor like these?

These are mine that I have not painted yet. I got them from http://www.jpiperformance.com Those will fit in that case plus he has smaller versions too. IMO you cant beat the performance/eye candy ratio

This what they will look like nice and painted up

saton472 · 02-26-2003, 01:01 PM

Thats sweet and all but i still want to build my own. For the setup i was thinking of something like this. its all copper

saton472 · 03-03-2003, 10:23 PM

any body got anything to say on my suggested design

Not really, I seen something very similar yesterday at the scrap yard. I think it was a AC rad. 1" think proably 12"x15". If I had time I would have grabbed it. Would have fit nicely on the side of a case. They are only $9 at the scrap yard.

Give it a shot and let us know how it works!

saton472 · 03-10-2003, 02:40 PM

I will, i just need to get some money ( and a job). im only a tenth grader. Donations are most welcome. PM me and ill give you my adderes.

bikr · 03-10-2003, 03:05 PM

why not build a cooling plate.. lemme draw one up , brb

ok , there you go. Water goes in and spread on a thin layer of copper , this can be placed almost anywhere.

saton472 · 03-10-2003, 07:34 PM

can you be a little bit more spicific

bikr · 03-10-2003, 07:36 PM

umm.. sure.. haha.. ok basically it's to pieces of flat copper sandwhiched together with a wall running down the middle of the 2 . water goes into the inlet and spreads along the plates , this gives HUGE surface area and lets you cool better.. I can't find any pictures of them.. but I've seen it done a few times before.. --Bikr

saton472 · 03-10-2003, 07:40 PM

how well does it work

bikr · 03-10-2003, 07:42 PM

when sysfx used to sell them , i heard tale of them outperforming 4" radiators can't back this up 100% though.. it's worth a try.. run it on a pelt as a test bed with no cpu , just pel + the system see what temps rate compared to air. --Josh

saton472 · 03-10-2003, 07:47 PM

I actually refuse to pelt my system. the main reason being all the horrer storys that iv heard about them accedently forgetting to turn them off or on

saton472 · 03-12-2003, 09:32 PM

Come on someone has had to have built ther own heatcore
