Cooling thermocouples junction

[harsh077]

please let me know
how to cool the junction of thermocouple...
is it possible to give current to both the wires n get junction cooled...?

The Electrical Engineering forum is probably a better place to post this question. Thermocouples are a type of temperature sensor and are not meant to actively heat or cool anything.

Peltier effect

I didn't realize Peltiers were also technically thermocouples, but since one junction gets hot while the other gets cold, it still won't result in an overall heat loss.
