TEC modules (thermoelectric coolers) are designed for cooling and heating, depending on the direction of direct current. When the current flows from the negative direction to the positive direction, TEC will start to cool, and conversely, it will start to heat. TEC modules have been widely used for controlling the temperature of laser system, refrigerator cooling system, air conditioner, computer CPU and so on. (more)
