Peltier Experiment

[Tecnho]

And above all photos we want fresh photos, create a new thread that those things are always liked.

regards.

yes of course, the first thing to say is that I'm new, and if I mess it up I'm sorry, well first of all I got this radiator

as I said it's from a laser hair removal machine, which inside has 6 peltiers, I thought those 6 peltiers were excessive and said well I'll use fewer, I decided to use 4 of them here you have two of them

on top of these peltiers are the tubes where the water passes, to give you an idea here you have another photo

in this last photo is where the water tubes pass, it has two inputs and two outputs as you can see here

HardLimit

and here is the water pump that I'm going to use
HardLimit

the idea is to make a water circuit where the peltiers and the radiator with the fan that cool the water go to the microprocessor, the water cools and pretty well, in a mini test, putting hot water in a container, passing through the pump and then through the radiator with the peltiers, the water came out nice and cool, let's see how the invention works, that is, everything is homemade 100%

It happened to me exactly the same as Kernel1.0… when I saw the avatar of Espinete I gave a big cry, but when I saw the date of the post... disappointment :cry:
The system you propose is interesting, we will see how it goes.
The photos look good, good luck.

Best regards!

ajja it happened to me too

about the project in question, if you have any doubts about the inventions with peltier cells let me know and I might be able to help. although it doesn't have computer applications, I've also made some inventions ¬¬ with peltier cells

[nuck]

@incrediboy:

ajja a mi tambien me ha pasado eso

sobre el proyecto en cuestion, si tienes dudas sobre los inventos con celulas peltier avisa que igual te puedo ayudar. si bien no tiene aplicaciones informaticas, yo tambien he hecho algun invento ¬¬ con celulas peltier

aplicaciones informaticas como cual? esta noxe subire mas fotos de como va el proyecto, ya empieza a cojer forma, no asustaros, ajajaj, un saludo y gracias x este calido acojimiento, me siento como en casa

[incrediboy]

I said non-computer applications, like freezing a can of soda in seconds, for example :fuckyea:

[nuck]

and how do you manage to lower the temperature so much??

[defaultuser]

If temperatures can be lowered as much as you want, I will make you a custom system for the temperature you want.

The problem is the final consumption, and also the cost of assembly, and both are getting more expensive as lower temperatures are desired.

Regarding what you said about cooling water with peltiers, those designs of yours make me think they are an excuse to cool the room.
In any case, watch the dew point temperature if you are not going to protect the socket.

the zocalo I think was with this

@nuck:

y como consiges bajar tanto la temperatura¿¿

con 4 peltier bien refrigeradas. el consumo de las 4 no sabria decirtelo ahora mismo, pero estaba entre 500-550w

@defaultuser:

Respecto a eso que hablais de enfriar el agua de una liquida con peltiers, esos diseños vuestros me hacen pensar que son una excusa para enfriar la habitacion.

enfriar la habitacion? ¬¬

piensa un poco en lo que has escrito, las peltier tienen un lado frio y otro caliente, y si enfrias un objeto en concreto… a donde va tooodo el calor del lado caliente? pues eso :troll:

[nuck]

@incrediboy:

with 4 well-cooled peltiers. the consumption of the 4 I couldn't tell you right now, but it was between 500-550w

the heatsink in the photos is large and the two fans are also large, here you have how it is mounted in the pc case

[Franziskaner]

hello
well I don't know what to tell you. I personally think that if you mount it on top of the tower, it will gain a lot aesthetically and you will have less distance to the CPU which I imagine is what you want to cool, right?

@incrediboy:

"…

cool the room? ¬¬

think a little about what you've written, peltiers have a cold side and a hot side, and if you cool a specific object... where does all the heat from the hot side go? that's right :troll:

No man no, what I meant in a slightly sarcastic way is that if the cold area isn't insulated well, a lot of cold is lost.

All components that are below ambient temperature and not well insulated will be taking heat from the environment, that is, the less insulation the less efficient the system will be (insulation in tubes, cold side of the peltier, micro block, and even the return tube would need to be insulated if the cool water returns).

Good idea to use parts from the laser epilator, the only problem is that cooling the hot side with a standard heatsink will probably make a lot of noise.
The ideal would be to cool the hot side with a second independent liquid circuit, and with a generous liquid radiator, almost no ventilation would be needed.

Then there's the problem of condensation on the micro, and it's that when the micro is working it will have very good temperatures, but when the micro is idle the temperature of this will drop more and more, and when it drops below between 24º/10º (varies with ambient pressure, humidity, and temperature) dew will start to form first on the micro block, then on the micro itself, and if the micro remains idle, dew can even form on the micro's own legs.
That's why I said to protect the socket against moisture condensation.
The perfect solution would be for the peltiers to automatically regulate themselves via PWM based on the temperature of the liquid, but I've looked a bit and couldn't find a suitable circuit on the web, it would have to be made.
An easier option would be a circuit that would turn the peltiers on and off via relays to maintain a stable temperature.

Well, for what it's worth, many beautiful things could be done, mind you, it's not that I want to take away from the importance of the build, just to emphasize certain aspects to be realistic.
The colleague's build is a good idea and will save him a lot of trouble by having taken advantage of the parts from the epilator, the only problem is condensation and extra consumption, but anyway, as long as that PC is only for gaming and he has another for more trivial things, and as long as he's careful with condensation, everything is perfect, to power up the machine and have fun making it yourself.

Regards.

PD:
How much pressure does that pump in the photo put out? it looks good, if it's high pressure, make sure there are no restrictions in the circuit to avoid damaging anything (block for example).
