Refrigeracion con Celulas Peltier

Refrigeracion con Celulas Peltier (TEC Cooler)


Las células Peltier son otro de los métodos de enfriamiento usados para hacer overclock extremo. Su uso no esta muy extendido dado que la relación coste/rendimiento no es de las mejores teniendo en cuenta las soluciones alternativas que hay, asi que no voy a alargar mucho la entrada.

Estas células se basan en el efecto Peltier descubierto por Jean Peltier, y que a grandes rasgos se basa en interconectar metales parecidos (tipo p y tipo n) entre sí a través de la unión Peltier.

Definicion: Consiste en la creación de una diferencia térmica a partir de una diferencia de potencial eléctrico. Ocurre cuando una corriente pasa a través de dos metales similares que están conectados entre sí en dos uniones (uniones Peltier). La corriente conduce una transferencia de calor desde una unión hasta la otra. Una unión se enfría mientras que la otra se calienta. El efecto es utilizado para refrigeración termoeléctrica.

A efectos prácticos lo que se consigue es que una cara de la célula esté muy caliente y la otra esté muy fría, la cual será la que acoplaremos al procesador para darle un extra de frío.

Ahora vienen los contras. Las células Peltier decentes, las que montaríamos en nuestros ordenadores, disipan entre 100 y 150 W (superándolo en muchos casos), ya que tienen un consumo de energía altísimo (entre 5 y 15A, llegando hasta los 20A). Ésto implica que tener el microprocesador a una temperatura aproximadamente de 30 - 40 ºC por debajo de la temperatura ambiente, pero a la vez tener una cara caliente que nos esta disipando el mismo o incluso más calor que la misma CPU, con lo cual hemos de acompañar la célula con un disipador u otros métodos de enfriamiento que he enseñado en entradas anteriores.

Eso sí, si no nos importa el consumo y tenemos una buena solución para enfriar la célula, podemos tener un equipo funcionando 24 horas al día a una temperatura en la mayoría de casos bajo cero.

AMD ha patentado la utilización de células peltier para la refrigeración de microprocesadores, según la patente Nº 6.800.933 de la oficina de patentes de los U.S.A.

La peltier como método para refrigerar micros con tecnología de 0.065micras se podría conectar a 12v. Pero parece ser que aún es pronto ya que faltan cosas por esclarecer como el precio que costaría tener este sistema.

Espero les haya sido útil, un saludo muy grande para GeeKtacora por el articulo, Patagonian.

I've as a last resort liked things like sand clocks, lava lamps, and the like to type of virtuous spend all at once staring at it as a cut of catharsis. In a route, it helps me with meditation, to mitigate emphasis and scarcely deem in the air nothing. That's why since I was a kid, a substitute alternatively of dolls and cars I've always collected more of such pieces like sand clocks, lava lamps, dulcet boxes etc. So I was most charmed when I base the[url=http://www.dealtoworld.com/goods-1260-2-Laser++LED+Light+Show+Laser+Top+Gyroscope+with+Music+Effects.html] 2-Laser + LED Shine Manifest Laser Outstrip Gyroscope with Music Effects[/url] from DealtoWorld.com under the Toys section. It's like a harmonious caddy, a spinning top, and a berate show all rolled into one. Which is great amusement! The gyroscope pleasure spin object of in the air a minute. The laser enlightenment show with accompanying music makes this gyroscope a pretty corresponding exactly fiddle with that my friends get also been most amused with.

My dogs are also nice-looking eccentric prevalent the laser gyroscope I got from DealtoWorld.com. They evermore occupy oneself with the gyroscope as it spins, although at first place they kept barking at the laser light advertise, and also because it produces music. But after they got used it, they've stopped barking but due watch over following the gyroscope whenever I start spinning it. Kids are also pretty amused nearby it. On occasion it's moral to possess pleasing toys around the house so that you can desert the small on while the kids are being amused or playing with it while you go fit out food or fall heir to changed. The gyroscope is unified such fool with with this purpose.

The gyroscope I bought from DealtoWorld.com has a dragon as a design on it, and produces a light accompany with red, dispirited, and unripened colours. Steal a look at the pictures I've uploaded of the gyroscope with laser incandescence show. The music produced from the gyroscope is not that renowned but decorous sufficiency to entertain any supplementary customer to the house. The gyroscope is red and negro, making it look exceedingly cold, and measure virile with that dragon imprint.

The music light make clear gyroscope runs on 6 LR44 batteries, which are replaceable anyway. I've also euphemistic pre-owned this gyroscope to stagger my girlfriend during our anniversary celebration. I did the cheesy matter of decorating the hostelry elbow-room with roses and when I led her in, I started up the gyroscope as correctly so that the laser brighten clarify produces a dreamed-up effect. I also had some battery operated candles so all the moonlight effects created a sort of romantic atmosphere. She loved it, past the custom, to my relief. I also bought the candles from DealtoWorld.com. These days it seems to be my non-fulfilment shopping site for all gifts and ideas in behalf of romantic occasions.

Since Christmas is coming, this laser light show gyroscope can maybe be a great Christmas give-away in behalf of the toddler or in spite of the humour! Alternatively, the gyroscope can simply be a polite summation to the usual Christmas decorations. I can fancy placing it adjoining the Christmas tree and maybe spinning it when guests succeed in the house. Looks like [url=http://www.dealtoworld.com]DealtoWorld.com[/url] is getting my duty yet again!

In my opinion, it is an interesting question, I will take part in discussion. I know, that together we can come to a right answer.
Between us speaking, I would arrive differently.
I apologise, but, in my opinion, you are mistaken. I can defend the position. Write to me in PM.
What remarkable phrase
You were not mistaken
