"RADIATORS" Please give some Reviews, Theory, Comparisons
I know radiators cool water , but I'd like to know some comparison on who's got more cooling power.
Different uses, different capabilities what details are there about it? Any new links or knowledege out there? Thanks for the inputs, and please keep them coming Last edited by j813; 02-25-2004 at 02:35 AM. Reason: Emphasis |

There is a huge range in rads. Amoung the "made for water cooling" rads they start with the "micro" rads that are just big enough to fit a 80mm fan on them for cooling. Micro's are long on look and short on performance. The other exteme amoung the custom made for water cooling is the 120.3 rad which can take 3 120mm fans per side.
Heater cores offer the best of performance, but require some modding skills to alter the cores inlet/outlets and custom make shrouds to mount the fan(s) on. A large heater core that can take dual 120mm fans per side offer massive cooling. The sinlge pass core from chevy pick ups 69-72 offer very low resistence to flow and thus extreme cooling potential, they can take dual 120mm fans per side. |

Thanks
Heatercores why is it different from Radiators, if it is? Is it also because of materials used? And what if I use a Radiator from a Car? |

and how about those, radiators found in air-conditioning units similar to how & what vapochill use.

Those are poor performers at best. They restrict flow a lot, and don't offer as much water/tube/fin surface contact. They are designed for cooling the liquid as much as possible, rather than removing as much heat from the loop as possible. (A heater core will take a fair amount of heat from a lot of water) A radiator from a car is good too, but large, and expensive. What you are looking for is a heater core STYLE radiator, and a heater core is the best of those, due to price, size, and performance configurations.

I see.
Problem is we dont have it here because we dont we have winter here I was planning to have one made by an air-condition rad manufacturer, copper tubes with copper fins or no fins @ all. |

i have a black ice extreme on my setup with a single 120mm fan with shroud. i believe that the tubes carrying the water are actually "flattened" in order to increase the surface area, and therefore the heat transfer. also , if you look at any auto rad, you'll see they all have fins to help increase that area. also, most good radiators are copper, or aluminum. although i believe that copper is the best. for the mathematically inclined, there's plenty of reference material out there that will help you size components if you're building your own rad.

traditional radiators or one or two long copper tubes that make multiple passes, each pass being a graduated 360 bend
this amounts to alot of restriction heatercores, of which the Big Arse, and Black Ice are examples, have heatplates, those flat pipes- these are set in parallel and so the overall restriction imposed by the heatplates' flatness is compromised heatercores like the bix the ba and the ss3 and 4, have two passes of these heatplates, up and down, so the fittings end up on the same side of the rad (convnience) |

So getting a used Car Rad would be more nice?
I really thought those little spaces a Car Rad have, would restrict the flow more than an Air-Conditioning Rad. Ya I might find Rads from the Rad fix it guys and modify the in @ outlets, what do ya think guys? Thanks |

They have a LOT of little spaces, and they only have 1 turn, or maybe even none. That sounds like a good idea, but it will take up a lot of space.

mm with heater cores you guys mean the radiators used to heat the air INSIDE the car right?

Sorry i forgot to attach a file guys.
Im building myself a WC kit and i already got a radiator of a old bike it`ll fit a good 120 mm fan i think do you guys think its fine? its slightly larger then a 120 mm fan and its also aluminum ( ) |

but then you have to make shure that all your waterblocks are aluminum as well. most of the heater cores used are copper. copper trnasfers heat better then aluminum. if you mix metals.. aluminum rad and copper waterblock. you will get corrusion. exacly why it does i'm not shure .... mebe someone else can clarify it better.

You wont get corrosion with a corrosion inhibitor, such as a small amount of antifreeze and good pure water. Also, that radiator is nice because it has a built in resevior/fill tube Pretty good idea if you ask me.

Found this link to help us curious about Copper & Alum corrosion prevension. |

Fairly large amount of antifreeze, I believe, if it is unprotected aluminum. Maybe 30%.

Anti-freeze, water wetter or a similar anti-corrosive additive for car engines will do fine.

Can someone please tell me how thin are the "plates of those tubes" used in an effective Core or Rad? Thanks
