To provide a drying apparatus for drying clothes by using a heat exchange technology capable of attaining a high drying efficiency.
The drying apparatus includes: a housing tub for housing clothes; a blower for feeding drying air for drying the clothes to the housing tub; an exhaust duct for guiding the exhaust air exhausted from the housing tub in a first direction toward the blower; and a heat exchanger for exchanging heat with the exhaust air flowing within the exhaust air duct to generate the dry air. The heat exchanger includes a main exchanger disposed in the exhaust air duct and a sub exchanger disposed outside the exhaust air duct. The sub exchanger includes a heat exhaust apparatus for exhausting heat transmitted from the main exchanger and a cooling apparatus for feeding cooling air for air-cooling the heat exchanger. The cooling apparatus feeds the cooling air in a second direction different from the first direction.
