Peltier wine cooler

Electronics / Homemade homemade
Added 43 commentary

The master who built this refrigerator, is an electronic engineer with a diverse range of hobbies, from history to sports, from jurisprudence to travel. The last passion of the master of wine making in home conditions. And here his engineering knowledge came in handy. Not for making wine, for storing it.

The wine should be stored at low temperatures from 10 to 18 ° C maximum, and refrigerators for its proper storage of the road. Then the master decided to make such a refrigerator himself.

Tools and materials:
-Extruded polystyrene foam;
- Aluminum tape;
-Roulette;
-Glue;
-Knife;
-Pencil;
-Aluminum profiles;
-Aluminum radiator;
-Fasteners;
-Drill;
-The Peltier element;
-Textolite;
-Fan;
- Controller for powering the Peltier element;
Peltier wine cooler

Step One: Refrigerator Requirements
When designing, the master tried to take into account the following requirements:
- The temperature inside the chamber is not higher than 18 ° C
- Low power consumption of 15-20 W
-Work on the Peltier element
- The controller with a control system and control of the set temperature

Step Two: Housing Design
When posing the question of what to make the body of, the master settled on penoplex. The master explains his choice of material with its low thermal conductivity, moisture resistance, strength, ease of processing.

For the refrigerator, the master used plates 4 cm thick. The internal dimensions of the refrigerator are 380 x 360 x 320 mm. Four five liter wine bottles are placed in such a refrigerator.

Step Three: Camera Making
The master took the foam sheet to the furniture workshop and there it was cut to size. Assembling the camera with the master uses glue.







After assembling the camera, paste over it with aluminum tape.



Step Four: Cooling Unit

The design of the cooling unit is simple. As we know, when voltage is applied, one side of the Peltier element cools, the other heats up. Therefore, positioning the element inside the refrigerator is inefficient. The master places the element from the outside with the cold side to the internal radiator, and hot to the external.A fan is installed below the element. The design is visible in the photo.












The master installs the internal radiator at the top of the chamber, this is due to the lowering of cold air down.
Step Five: Controller
The controller has the following parameters: measuring and adjusting the temperature with an error of 0.1 degrees in the chamber, limiting the power consumption, monitoring the temperature of the external radiator and turning on the fan, continuous power to the Peltier element, smoothing the ripple and power surges.

The master emphasizes that the Peltier element works constantly, just with different power. Such a scheme will allow the element to work much longer. The controller diagram is located below, and you can get more information.


Tests of the refrigerator work masters quite satisfied. But he is not going to stop there, and according to him, he will continue to work on increasing the efficiency of his work.

Tomorrow I will find my articles with the correct spelling of the word. I may not understand the electrical circuit of the device, but I know the difference between the controller and the controller. And the spelling is so, for another reason. But if it’s so interesting to tell.
I write in the text editor of the site, then select the text and paste it into the Word (sometimes the spelling on the site and in the word do not match). I am writing quickly, on the machine. I correct the errors after the Word. When you write on the machine, there is simply no time to think about the controller or the controller. All later. But this time the word played a cruel joke. Correctly both the controller and the controller. And when checking, you scroll down the page and you look with blue-and-white vision with blue and red underlining, without reading the text. Something like that. In general, my opinion, the incorrect spelling cannot serve as a criterion for assessing the knowledge or ignorance of a subject. Are there few examples when literate people speak illiterate?
Some "sucked" Matvienko what are they? But this does not mean that she does not know what it is.

This is not a grammatical error, many authors and scribes have many of them here, to find fault with this is pointless and impossible. The point is ignorance of technical terminology.

Not turn out, and defend your point of view
And you answer why exactly your complaints most disagreement
For starters, it would be nice to tighten up your grammar and syntax. Further, to master the culture of discussion, try to understand the essence of what your opponent is trying to convey to you. If you do not understand, I will explain. I talked about that to the statement of material Dmitry, unlike you, has practically no questions! Dmitry and other serious authors, as a rule, correctly respond to comments, answer the case, and you perceive them as
exactly on your claims most disagreement
And basically your unjustified disagreement! smile

Well, my opinion is that the scribe should still understand the topic that he writes. I’m not talking about super deep knowledge there, but just about understanding how everything works. And if I make such mistakes, then I respond to such comments.

As for the typos ... they are all done. If the same Ivan Pohmelev could write 30K characters in a day, at least there would be no less mistakes (typos) than mine. But he will not write at such a pace and 5k per day.

And who will write in small volumes at this price? No one, you won’t earn anything. And the admin doesn’t need to pay more for a super spelling text, and nobody needs it either.

The greatest value of content is readability and informational content.

Do not twist, but defend your point of view. But there is no secret. Dmitry is simply not responding to half the comments. You wrote, he did not answer. And everything has sunk into oblivion. Probably doing the right thing.
And you answer why exactly your claims are most disagreement. Maybe because you, too, not always knowing the material, are trying to judge?

Please answer at least to yourself: why to your statement of material most comments? More than to everyone else combined? Apparently Dmitry and other authors write about what they know, and comprehend the material presented, and are able to correctly recognize errors, and do not try to get out by hook or by crook! smile

The controller is a mutant in the S.T.A.L.K.E.R. series of computer games, capable of taking other living things under telepathic control.

-You talk nonsense. You go to my profile and see what articles there. On a variety of topics. Or to Dmitry who has 1000 articles. Do you seriously think that all these topics can be known? From electronics to casting, from steampunk to caravan, from working with epoxy to arduino? This is all chewed-chewed many times.
And about the controller-controller, these are production costs. You will begin to understand writing.

And now on the topic: the cold bridge is not insulated (aluminum radiator) can/ it was necessary to isolate everything before contact with the Peltier element. "Fan" is not clear., Then it is better to use needles.)) - why not a thin and wide plate? - for example, to the bottom or to the top ?. p.s.Given the temperature range - try using a coolant such as vodka in the tubes around the perimeter. It will cool longer, but also keep the temperature longer.
There are no comments on the scheme; the idea itself is not bad. (trying to make a "good" humidor)))) - so in the subject.)
