Reversible PID control for a Peltier module
2009-06-14 02:57:00 Hi users! I need to control the temperature to 20ºC in a plate using a 12V, 80W Peltier module. Previously I used a CAL3300 digital temperature controller, but I had some issues. The CAL controller (and most that I have compared) works in DIRECT mode to freeze and in REVERSE mode to heat. The
Heat Transfer Design Using Peltier Heat Pumps
2009-03-09 18:32:00 I have a challenge to design a bit of test kit for our production guys to calibrate temperature tranducers. In effect it will consist of a flat bed, the temperture sensor of the tranducer unit is a flat metal surface to be bolted to oil filled National Grid cables, transformers etc. and these wi
PID Controlling a Peltier based cooler
2008-11-26 23:31:00 Hi group, I have a small cooler based in peltier to control the inner temperature of the chamber. I want to use the thermal module (with peltier, fan and heat sink) to control the temperature in a aluminium block of 7x7x7 centimeters,the setpoint is 18ºC, the room temperature is 25ºC. (I
Peltier TEC
2008-08-26 17:48:00 My inquiry is about a Peltier Thermoelectric Cooler. First of all I would like to give me information about the power consumption (watt) of a commercial TEC with dimensions 40 mm x 40 mm in order to create a temperature diffrential of say -25 Celsius (Ambient temp Ta=35, Tec Cold Temp
How to control the temperature in a Peltier based cooler
2008-05-18 08:57:00 Dear Group, I have purchased a Peltier based beer cooler, this product can store in its interior 8 beer cans and have two modes operation, hot and cold. The cold is almost 4°C and the hot is almost 60°C. I need the control the temperature in 20°C in the interior (not for beers, of course)

Peltier Cooler: El posible futuro de la refrigeración de CPUs y GPUs
2008-01-12 19:35:00 El efecto Peltier se puede encontrar cuando tenemos dos metales distintos en contacto. Al aplicar una corriente entre los metales podemos hacer que uno se enfríe mientras que el otro se caliente.Basado en éste principio una compañía con el nombre de Nextreme desarrolló una versión en miniatura de un cooler que usa el efecto Peltier para posiblemente enfriar pequeñas regiones en un chip.Usando pequeñas bombas de transferencia de calor por efecto Peltier se podría diseñar un CPU o GPU donde las regiones más activas del chip donde se emite la mayor cantidad de calor puedan ser enfriadas localmente.Con el uso de sensores de temperatura y bombas de Peltier distribuidas en un chip se lo podría enfriar inteligentemente logrando así aumentar la frecuencia en la que trabaja el chip e incrementando su rendimiento.También podría usarse el efecto Seebeck que es básicamente el inverso del Peltier. En el efecto Seebeck una diferencia temperatura entre los metales crea una corriente que se puede u...

Chip with its own Peltier cooler
2008-01-11 14:40:00 From Boing Boing: North Carolina's Nextreme has announced a chip with its own built-in Peltier cooler -- a cooling system that uses electricity to move heat from one side of a surface to the other. These are historically very expensive to use -- bulky and energy hungry -- but m
Lee Peltier Heads For Yeovil
2007-07-30 13:46:00 Lee Peltier won’t be featuring in any manner for Liverpool this season - he’s packed his backs and gone to Yeovil on town for the season. Not only that but he managed to squeeze in a game for them over the weekend before the loan deal was rubber stamped today. Peltier got a handful of games ...

Book Review: ?Cesar?s Way? by Cesar Millan, with Melissa Jo Peltier
2007-06-19 03:27:00 Cesar Millan, host of National Geographic Channel?s ?Dog Whisperer?, brings his knowledge and technique to millions more through his new book, ?Cesar?s Way.? This engaging and comprehensive non-fiction work begins with Cesar?s life story growing up in Mexico and the steps that brought him to such an incredible understanding of dog psychology. It then goes on to detail what behaviour patterns are most common in North American dogs, and how to use his techniques to build a deeper bond with your dog, eliminating dangerous and unwelcome behaviours in the process. He illustrates his points well with stories of how he has helped both ordinary people, and celebrities like Oprah and Jada Pinkett-Smith, to have better relationships with their dogs.
Peltier Effect
2007-05-17 16:28:00 Can you use a peltier in the opposite direction, so that you get electricity out of it? Can you calculate it how much you get out? |
