No competition, why only HWlabs?

Do you mean you have one specially made for you?
I was able to talk with a guy in SouthAmerica and he has a contact manufacturer that can give him a fairly priced ones; same here in my place also.
My question is; is the pricing of HWLabs Rads with freight charges already?
If so why is it we here in my place have the same pricing when I know HWLabs have their units manufactured here, also their office is here. Maybe for equal pricing? my guess

No it wan't specially made, it was the plain brand for a specific make of car, it's a Transpro brand I think.

how much are you guys willing to shell out on something like this:
that's a handmade version dual120mm rad 3rows single pass rad... custom made w/ built in shroud... i didnt mean to compete w/ black ice... as hwlabs owner is a good friend of mine

lets just say i want to compete w/ your bad a$$ heatercore (hence the brute 3rows single pass approach)... but sad to say production costs in small quantities are really expensive...

here's the backside pic of it w/ 120mm fan:


also currently in talks w/ oem rad manufacturer for some jap car companies...

Make it one row single pass and you'd get more interest from me personally

im a bit surprised... all the while I thought the bigger the better

so would that be single 120mm or dual 120mm

Read Cathar's post

Bathman yun kila Dulber ba is 3 pass or maybe they meant three rows ano?

Likewise. I run a fairly hefty fan on my rad, but to get even close to adequate airflow on that I'd have to run it at maximum speed (which yields 55dBA and 0.768in h2o per specs). A bit much for my ears.

@phaestus,

point taken... eventhough the fins are widely spaced???


j813,
3rows...

[AngryAlpaca]

Widely spaced fins are not necessarily a good thing (probably bad) as that reduces the cooling effects. The thing is, though, that the back half gets MUCH less turbulence than the front half, so the back is just restricting airflow, not doing anything. Cathar is damned right about car blower noise though (have to shout, no motor noise, however), although that much pressure surprises me.

The heater core from a '79 Honda Civic is brass tubes with copper fins, I think, about 7"*7", and the barbs are already suited to half inch tubing. It's pretty good although expensive.

[BaThMaN]

ok then... how much you guys are willing to pay and what dimensions you would prefer??

[pHaestus]

If you are going to make double or triple thickness cores then do two things: (1) Make the fins more widely spaced and (2) offset the fins.

You know how this works; people will be willing to pay exactly what they would for a heatercore ($20 or so)

lol

[AngryAlpaca]

People are willing to pay much more if there are proper sized barbs and a shroud. You could do $30 without much loss of sales. I think your cooler may be too large, as well. We want good, compact, cheap, pretty, easy, and quiet. Got it?

[Butcher]

My current heatercore cost £5 (about $8) from a scrap dealer, can you beat that?

[BillA]

not as long as your MTBF is 'unknown'
mfgrs can't play that game, "Sorry" won't cut it

[Razor6]

I think $40 is a good price for a large rad but $50 or $60 seems more reasonable for that huge thing that was posted. I don't understand this talk of rows in relation to heater cores though, I thought that most heater cores were single row with 1 or 2 passes. What distinguishes the rows, pics?

How thick the fins?
Suggest that 30FPI x 0.1 fins would be superior - 8 mm between tubes

[psychofunk]

Can you guys post some pics of a rad that fits your descriptions. I think that what you guys are saying is that with someone like myself who uses very weak fans (the super low noise papst fans) would see better performance from a 1 inch thick core as opposed to a 2 inch core, assuming that...????....it has a larger frontal area.....what else please elaborate I cannot visuallize what you guys are saying.

I am very interested in this as I have been mulling over the idea of making a plexi box under my cube case (13x17x5) to act as a shroud for a couple of rads. Air would enter through the sides, pass through the rad up into the case where it would be exhausted from the top and if I am even in the ballpark of understanding what you guys are saying then a very large but very thin rad would work perfectly. Are there any rads that you guys can recommend? Or any bad things that you see in what I am considering?

30FPI is pretty restrictive if the fins are crenulated like I'm imagining they are.

The Nippon-Denso cores which are prevalent here in Oz have the fins cut and crenulated as well, so even though the metal is 0.1mm or so thick, the fin's cross-section is more like 0.3-0.4mm thick.

At really low air velocities through the fins the air tends to turbulate well enough for even fairly open FPI's to keep radiator efficiency high.

If the fins were just basic flat folds, then yeah - maybe a higher FPI. Would need to keep on eye on the pressure drop though.

i'll let the scanned pics do the talking:


thats how the fins scales to axp tbredB...

estimated costs would be around $30-40 for 120x120mm single row single pass... my main concern is how will i ship it there? (from philippines)... im afraid shipping it there would cost more
