PURPOSE: A table type cooling apparatus using a thermoelectric module is provided to prevent environmental contamination by not using refrigerant gas. CONSTITUTION: A table type cooling apparatus using a thermoelectric module includes a power supply unit(10), a transformer(20), a bridge rectifier circuit(30-1), a thermoelectric module(40), an inner air circulating fan(51), a temperature sensor, a temperature controller(53), a heat sink(60), and a blower fan(61). The power supply unit supplies power to the transformer of the cooling device. The transformer drops AC voltage received through the power supply unit. The bridge rectifier circuit converts the dropped AC voltage through the transformer into DC voltage and applies the DC voltage to the thermoelectric module. The thermoelectric module generates or absorbs heat according to the injection direction of the current. The temperature sensor senses the temperature of a container holder. The temperature controller maintains variably set temperature sensed at the temperature sensor. The heat sink prevents the heat from the power supply unit, the transformer, the bridge rectifier circuit, and the temperature controller to the thermoelectric module. The blower fan discharges hot air to the outside through the heat generated from the heat sink of the cooling device.
