ABSTRACT:
An temperature control apparatus includes a temperature detecting element (50), a control circuit (60), and a thermoelectric unit (70). The temperature detecting element contacts to a first surface (82) of a predetermined target (800). The control circuit is electrically connected to the temperature detecting element. The thermoelectric unit is electrically connected to the control circuit, and contacts a second surface of the predetermined target. The temperature detecting element detects a temperature signal. The temperature signal is input into the control circuit. The control circuit changes the temperature signal into an electrical current signal, and the electrical current signal drives the thermoelectric unit to control the temperature of the predetermined target.
