copper CPU cooler

[acfixer69]

I'm sure that they are both doing 55Kwatt but the shot gun will do more. Almost all the reflux condensers on the home build plated stills a way to big. In the build threads they all say that it's better to have and not need then to need and not have. This is true with a product condenser but not so with reflux. Oversize refux and the dwell time can be so slow that you have no idea whats happenin.
By the way I cut a cooling heat sink from an old laptop and what I had thought was solid copper was a heat pipe hollow with a fiber. I learned something today. Now I need to fined out what gas/liquid and get a P/T chart to see what gas would be best for stilling thanks this threat has poked me to the eye in a good way.

Even if this experiment don't work, all isn't lost.
My old dog will get to chase and bark at the UPS

I hear they take selfies with dogs along their routes now....

Was the fiber wick removable

[acfixer69]

It looks more like ribbon strips when I used a cut off tool to open it up. They are glued or something.

Do an image search for heat pipe cross section. To make your own wicked heat pipe, you might get away with lining it with copper braid.

[shadylane]

This has been a learning experience for me. A few days ago I didn't know about heat pipes.
In a couple more days, I'll get to destroy 3 brand new ones

Here's what's probably inside the heat pipes
It looks like all 3 wick styles would restrict the cooling water flow.
But, It should help transfer heat to the cooling water.

[acfixer69]

I learned a lot also, the one I tore up would have done a nice job cooling my SSR on my controller. I'll have another soon enough.

[NZChris]

The wick is for capillary action and is more important when you want the heat to flow against gravity.

A picture just popped in to my head of a steam-punk copper CPU cooler for a SSR or SSVR

[shadylane]

I removed everything I didn't need and replumbed the cooler.
Haven't soldered anything yet
Figure to have a couple shots of DIY Irish whisky first.
That should calm my nerves, or give me something to blame if I screw up

Don’t forget to add a Sterling Engine to run the fan and/or pump.

[shadylane]

A CPU cooler on a small Sterling Engine.
I like the idea.

[Kindafrench]

Maybe a fancy product cooler, but no vapour condenser.

CPUs may dissipate up to 200 watts, not talking about some watts on top for overclocking. That‘s what the cooler is made for.
„Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload.“.
Refer to CPU datasheets for more details.

But enjoy the Bastelstunde

[shadylane]

I had to google Bastelstunde
Got a little more done today.
It will now fit inside the 4" column.

Tidy work Shady

Did you soft solder or braze those tubes on ?

[shadylane]

Soft solder
I would have preferred brazing but the tubes are very thin wall.
The ID appears to be around 5.5mm
For the scientifically challenged Americans, the tubes are 7/32" ID

[shadylane]

Getting closer
The vapor out is 1" The water in, out and thermo is 1/4"

[shadylane]

4 cents.
A drop of condensation would fill those gaps between fins and there goes the surface area. AND don’t even think about what it would take to clean after a puke w/o ruining every fin.

Otis

A little while @ 100% reflux should gently clean puke from anything on the vapor side
I think the fins probably would get water logged.
Hopefully alcohol vapor, acts different than water.

[Kindafrench]

Hopefully alcohol vapor, acts different than water.

Some of the vapour will even condense to alcohol and will act like. Watch the sides of a wineglas filled with water and one with wine. Would be interesting to see a photo with fins dipped in alcohol and fins dipped in water. Maybe not a big difference in cooling efficiency.

Looks cool af. Eagerly awaiting the results on the finished condenser. I'm in the little faith boat right now tho.

[shadylane]

Your not the only one in the little faith boat
The finned dephlegmator is finished. I'll probably start testing tomorrow.
I'm also cleaning up the shotgun and dimroth dephleg
Figure a little competition is in order

[shadylane]

I'm surprised the finned dephleg actually works
Here's where I compare it with some the other dephlegamators I've build

High five

[shadylane]

The dephleg made out of a CPU Cooler worked. But it was a water hog
It needed more cooling water tubes than it had.
It sure was a pretty piece of copper porn
Unfortunately, a simple dimroth outperformed it, by being more efficient, easier, cheaper to make and less likely to leak.

[Yummyrum]

Nice work Shady . I have to say I’m supprised those 3 coils pulled as much heat as they did .
Good onya for seeing this through .

[shadylane]

It could knock down almost 7kw but it needed 8 liters a minute of cooling water
The shotgun and dimroth could knock 7kw down with 1.5 L/M

[Chauncey]

This makes me think...

Do fins have a use in condenser efficiency improvement seeing as they helped that little bit of coil function as a dephlag

So how can fins be incorporated to the more efficient designs we already use - and further how can their addition be executed combing ease of construction and low cost with greatest efficiency?

[shadylane]

I kinda think some fuzzy 3/8" tubing would make a good dimroth.
Now, where the hell can I find some of that in copper or SS

[Yummyrum]

Wondering Shady if you connected the three tubes in series to make a more traditional dimroth would it be much different to the three coils in parallel .

Likewise wondering if a multi loop parallel connected cooler like you did but with many more loops would be a any different to the same number of coils n series ?

I know the copper scrubber did nothing in your dimroth test but maybe that was because it was already efficient enough . Would three turns on there own then benifit from copper packing as it may act like the fins

[acfixer69]

The fin design was meant for air over heat removal not as a condensing function latent heat as a heat tube exhaust not the load.
