Peltier module is also called TEC module, short for thermo-electric cooler. ATE1-07 series Peltier modules come with 7 pairs of Peltier elements inside the module. There are two flat ceramic plates on the both sides, which are used to be mounted onto other surfaces by inserting thermal conductive materials, such as thermal pad or thermal conductive paste. This Peltier module is used to regulate the temperature for objects and stabilize the temperature in a certain temperature range. TEC modules...(more)
