Cooling and Heating with Peltier Controllers
Time : 2015-09-02 12:25Source :analogtechnologies Author : Analog Click :
Thermoelectric cooler becomes more prevalent in thermal system design. Thermoelectric cooler is the fastest and most compact method in temperature control. Heat transport will be produced when the current goes through the peltier elements in peltier cooler. One side of the peltier cooler is attached to a heat sink and the other side is attached to the object. Then the object will be cooled or heated, depending on the direction of the current. The peltier controller can generate currents when a target temperature is set. The peltier controller should have a sensor input.
The selection of peltier controller firstly lies in the output current and power supply voltage. Then more factors can be taken into consideration, such as accuracy, stability, efficiency, module size, safety factors, etc.
ATI provides a series of peltier controllers, and these controllers provide interface ports to configure set-point temperature, the max. output voltage, and the compensation network. They come with a 3V reference voltage of high stability and low noise, which is used to set the desired object temperature. They also provide temperature measurement and monitoring, power up delay and quick shut down.
