Hello,
Has anyone realized constant-temperature cell by "peltier effect", I found it used in laser field to control temperature, but how to realize it by the cheapest cost?

| The semiconductor made peltier cell still remain an expensive component due the large amount of semiconductor inside and due it's "hybrid" (rather than monolitic) nature.

You can find a diagram for a controller of peltier devives in [url]h**p:\\www.oatleyelectronics.com[/url]. Go to peltier devices and at the end of the page choose Peltier Controller. On the next page choose Download Instractions. This is the circuit diagram in pdf format.
It is not a constant temperature controller that can heat or cool automatically according to external temperature but it coould be a good start.

A friend of mine used peltier ellements to cool a laser.He says that peltier is effective up to 200 W.Note that peltier ellement is based on thermoelectric effect and it`s also consumes energy.
Here are parameters of such ellement
Max current 6 A
Max Voltage 15.4 V
Max cooling 53 W
Max temp. Difference 71 K
resistance 2.2 ohm
Dimmension 40x40x3.9
For schematic of a peltier cooler with controller:

Hello, thank you for your suggestions!
Another question, is there a tech to combine the "peltier effect" cell with the IC to one package (Cooling system and IC on a Chip)?
