Project: Blizzard 1230 IV - Heat Pipe Cooling System

Yoto · 16 January 2009, 17:44

Just had an idea based on Heat Pipe "tecnology", used mostly on portable pc´s.
Im thinking about building some kind of trapdoor for the A1200 that will use a "chunk" of cooper or aluminum with 5 to 6 mm, and some small pipes like the ones used in the back of refrigerators with 3 mm.
The goal is to make some holes in the "chunk" with the same size of the heat pipes and then fit them inside, for this purpose the trapdoor will have to be lowered in the inside by 3 to 4 mm.
The cooper holding the pipes will be in contact with the CPU and dissipates the heat along them as well as to the aluminum plate forming the trapdoor bottom.
I made a 3D draw with the concept, to give a better idea.
Fell free to share some of your thoughts to help improve this project.

It doesn't need it.

Hiyas Yoto

(sounds like Yo, Toe! *heheh*)

I like the idea and concept, I would add a couple of ideas if I may...

Small set of feet to raise the computer by 10mm / 1 centimeter
a Latch to LOCK and UNLOCK the trap-door heat sink in place.
the Primary heat sink / heat exchanger on a subtle spring so it firmly presses against the CPU
alterable cooling block position for 030's and 060's

ohhh perhaps a range of fruity colours and flavours

@ meega

Well it dosen´t if you live in a country with a mild summer. Our summers easily reach to 40 º C.

DoogUK · 16 January 2009, 18:01

Brilliant idea for an 040!

Zetr0 · 16 January 2009, 18:02

@yoto / doogie

this method will only work for Blizzard-esq type cards that have thier CPU upside down, Apollo's on the other hand have thier CPU up the rightway. however nothing stops a small adaption of this unit to have the heat pipes come out and into the h/sink...

thgill · 16 January 2009, 18:03

I am not sure about the Blizzard 030 cards (been a couple years since I had one), but I know my Paravision 030/50 card doesn't anywhere near hot enough to be of concern.

Sometimes I leave my 1200 on over night for a couple days in a row...or spend hour upon hours unzipping WHDLoad packages and the bottom of the trap door barely gets warm. No hotter than you would experience from a modern laptop. Actually probably cooler than many of them.

But I agree with Zetr0, perhaps a universal one that could be adapted to fit 030/040 and 060 cards would be useful. Well, ones that have the cpu mounted on the bottom anyways.

Yoto · 16 January 2009, 18:15

Thanks Zetr0 for the ideas, i will add them to the project...not too sure about the colors and flavours though.

I was trying to solve this problem for my B1230, since i cant use my amiga during the day in the Summer, i believe some guys living in Australia also have the same problem.

Yeah, I'm worried about mine as it is in a tower & the motherboard/Blizzard is too close to the case side for me to even install a small heatsink

Hit 42C here with ceiling fan the other day...if I was near my machine I wouldn't have considered even turning it on!

Thinking of plumbing a fan through the small gaps towards it.

Yeah! i know...during summer i can only turn my 1200 at night...

But since you have a metal case, maybe you could use a "chunk" of metal firmly attached to the CPU to transfer the heat to the case, or you could drill a few breathing holes in the case and install the fan from the outside?

Fingerlickin_B · 18 January 2009, 01:56

I thought about that, but fan on the outside wouldn't be as neat as I'd like

AmigaFan · 18 January 2009, 16:29

I know I may be stating the obvious here, but you should take into consideration that a fan (or heat pipe) can only cool an object down to the same temperature as the surrounding air (at best).

rkauer · 21 January 2009, 06:37

Just to remember Yotoxi: don't mix copper and aluminium! They react very badly with each other, creating a oxidation who will act as an electrical and thermal insulator.

Be warned.

Yoto · 22 January 2009, 00:59

Thanks rkauer, i´ve changed the original design already, copper chunk will not be used at all, instead i will use an aluminum one. Single hollow tubes will also be replaced with several aluminum folds instead.

Then we have to hope the air around the "fan" or "heatpipe" is below ,(my 030 summer normal temp), 60ºC´s ...Damn!... I guess i can no longer use my miggy on Mars in a near future...

cosmicfrog · 22 January 2009, 11:56

er correct me if i`m wrong but don`t heat pipes have something in them that evaperates thus takeing the heat away as in your frige

Huh, I downt now wat yew ah saiing?

All pedant-powered antics aside, are you suggesting some sort of refrigerant? An "actively" cooled system would be the "coolest" ever...good idea!

Sorry for posting a tube link here but this is what I did to cool my 030. It works fine.

Looks like a very shoddy mod to be honest.

The refrigerant idea is amusing, maybe we should all strip old fridges from the tip and use the refrigeration equipment on our Amigas.

I put this on a hurry cause I wanted to upload this for a friend.
It was painted. Now Dremel made its miracle
