Clothes Dryer

A clothes dryer comprising:

• a cabinet;
• a drum provided within the cabinet to provide a space for receiving laundry;
• an intake duct through which air is supplied to the drum;
• a heating portion provided in the intake duct so as to heat air introduced into the intake duct;
• an exhaust duct through which air is discharged from the drum;
• and
• a heat exchanger provided inside the exhaust duct, the heat exchanger having a divided space in which air introduced from the inside or outside of the cabinet flows in a first flow direction, and air discharged from the drum flows in a second flow direction so that heat exchange is performed while the air flows in the first and second flow directions,
• wherein the first and second flow directions of air flowing within the heat exchanger intersects with each other.

A clothes dryer comprising:

• a cabinet;
• a drum provided within the cabinet to provide a space for receiving laundry;
• an exhaust duct through which air discharged from the drum is discharged out of the cabinet;
• an intake duct through which air is guided to the drum;
• a heating portion which heats air introduced into the intake duct;
• a heat exchanger provided within the exhaust duct and having a first heat exchange space in which air discharged from the drum exchanges heat with air introduced from the inside or outside of the cabinet;
• and
• a preheating member comprising a second heat exchange space through which air passing through the heat exchanger from inside or outside of the cabinet is guided to the intake duct so that air flowing into the intake duct via the heat exchanger exchanges heat with heat radiated from the intake duct in the second heat exchange space.
