PURPOSE: A clothes dryer is provided to improve the whole efficiency of a product by performing heat exchange between high temperature air discharged to an external and low temperature of internal circulating air again by using a heat exchanger. CONSTITUTION: A duct(20) is connected to a drum(10). A heater(30) is installed in the duct. The heater provides high temperature air to an inside of the drum. A heat exchanger(50) is mounted on the duct. The heat exchanger performs heat exchange between high temperature air and low temperature of internal circulating air again.
