Someone, please, chop this into two so I don't have to read it.
Between these two and BillA vs Dave in the other thread, well, sigh.... Its got nothing to do with a bloody radiator design subforum, even though its a topic worth "discussion"....

Wow... knew I should've signed on last night and checked this thread... */me starts brushing the empty shell cases into a tidy pile in the corner*

Back then also, the shipping costs escalated the price of the rads too much to import them into the UK unless bought in unrealistically large quantities - much the same problem that others are experiencing now with ThermoChill rads overseas... The solution to this issue was ThermoChill. UK Produced radiators, no importing, no sitting round with a middleman ensuring you your order had been shipped when it was still sat in their warehouse with half of it missing as they'd swiped it to give to a bigger customer... if there was a rush on a line of rads, no waiting months for restocks... we can have them back on the shelves within 24hrs these days... This filled a nice hole... list the UK Manufacturers in the watercooling scene... you only need one hand. Hell you don't even need a whole hand of digits... so anyone foolish with a jigsaw and lost a finger - join in!!

But this thread is getting a bit heated and off-topic, it does appear that everyone has had their say so perhaps getting back to the actual discussion of having a rad sub-forum may be in order. The idea of re-naming the waterblock design sub-forum into a "component design" sub-forum has merit in itself and would be IMO one of the better ways to go abt implementing it. |

The truth is being a marine has absolutely nothing to do nor does it add to the mix. Using it to describe some seemingly arbitrary honor code does more discredit than anything else.
So please, let's just keep that kind of babble away from this. At the end of the day, its actually a trading firm as far as its activities are concerned. I'm certain all the patriotic banter falls flat when you realize where he's actually sourcing his clones. A radiator sub-forum can be a good idea. The truth is, whatever improvements you apply at this stage has a considerable amount of engineering and tooling implementation required. There's the 100's of hours of wind tunnel testing and fan spec validation one would need to do and still make sure it'd do well enough when people insist on their own ventillation options. These things aren't cheap and I doubt PC radiator manufacturers would be willing to let such data go so easily with the usual suspects just waiting to get their powder-burned paws on them. Note I use the term "PC radiator" manufacturers. These heat exchangers aren't just "tubes and fins" as simplistic immitators would think. |

Hi Willie
the crux of the issue is data w/o data its all conjecture and degrades immediately to debating opinions and the data is so costly that none who have such will release it worth observing is that the designer does not have to be the mfgr, the QP rads are a case in point and, like Willie, there is another big step up ahead if you users would like to contribute, state what you would like to see in a new rad - then watch the scramble to make the product, IF someone thinks there is a real market (and not 6 extremists hyperventilating with each other, I'm reminded of the 3 fan rads) there will be a significant amt of comparative data released shortly, by the same source as ever performance data, not radiator 'design' data; good for inferences however Last edited by BillA; 08-18-2005 at 11:12 AM. |

OK! OK! I have to clock in on this thread.
I'm just a lowly dedicated watercooling overclocker. This thread is going to lead to the end of the disimination useful information to ME and many more like me. I've seen it happen elseware (IDENInsider.com...gone!) Moderator(s), It's a VERY interesting thread, but it's only sending this board downhill. And you guys...forget your personal beliefs, trials and turbulations...I (we?) don't care. A thread in rad design..GREAT!, let's go! |

how does something end before it has begun ?
no engn data has been posted on specific liquid/air heat exchangers, none - ever you have no real use for engn data, what you can use is objective performance data just treat rads as a black box, works just fine for wcing systems builders (for those that understand the data) |

Nice to see you up and running again Bill, motivating as ever.
Radiator engineers are a very cautious bunch when it comes to making conclusive statements, its always a lot of testing, tweaking, prototyping, testing, tweaking, prototyping, tweaking...and on and on. Fundamental factors remain the same, waterside/airside surface area, airside pressure drop, flow resistance...how far discussions go will depend on what people are willing to contribute along those lines. |

Well, my first reaction was to join in on you guy's esoteric flame fest by sitting all the reasons why engr data would be useful to me..I am an engr with significant experience in liquid transfer and heat exchange specs, design and installation in two industries....but
You're right, other than a few people here most would go right over their head....so Let's get on with a discussion of the various pros/cons of radiator designs AND performance data! I'm only trying to keep this forum useful to the people that are so grateful for it's existence. |

on the front burner
had to go back and delete a rad that was covered by an NDA which I had forgotten pretty soon "Radiator engineers are a very cautious bunch when it comes to making conclusive statements, its always a lot of testing, tweaking, prototyping, testing, tweaking, prototyping, tweaking...and on and on." designing rads is a humbling experience, sooo many ways to do it wrong |

I think you have to specify what kind of radiators are normally suited for which application. The flat tube and serpentine fin design was our configuration of choice for the Black Ice due to its high internal surface area, conductivity, and dimensional compression.
Oil coolers are designed to tackle the viscosity of the intended medium. Folks in the HVAC industry have other radiator types which they use, like round tube force-fitted across flat fins and heated to expand. This suits chilled water flowing through them as cooling coils. Similar configurations using thicker-walled copper capillary tubes are reserved for use in vaporphase applications. Charge air coolers (intercoolers) are designed to be air-to-air heat exchangers to cool down compressed air. billbartuska, we can have say the Black Ice Xtreme radiator in one configuration (specified fin density, specific louvre geometry, tube type etc.) and will perform better given a specific set of paramaters such as right amount of airflow or perform worse say given a very constricting waterblock with an inadequate pump. |

Although I agree with Bill that there is essentially no useful engineering data on radiators, I wouldn't mind seeing some of the home-made radiators that some people have put together.
We can get into discussions about radiator design, but the bottom line is that due to cost and performance, a heatercore will always come out on top. For those interested, the reason that any engineering data would not be usefull, is simply because many radiators are tested for their intended purpose (a car), and the testing environment isn't anything near what is involved in a PC, nor would it be measured the same way. |

Actually the tests done are similar to that of automotive radiators save that you'd need more sensitive airflow sensors and higher tolerance flowmeters.

"but the bottom line is that due to cost and performance, a heatercore will always come out on top."
where on earth do you get this stuff Ben ? please substantiate with data |

Considering the cost factor thanks to scales of economy, very basic manufacturing processes and the general size of heatercores, the performance-price punch is pretty remarkable.
Now since the industry is "expanding" the issue of aesthetics, ease of use, and versatility are added to the soup, the "added value" comes into play. |
