A housing for modularizing a heat pump system of a clothes dryer and a clothes dryer having the same are disclosed. The heat pump system modularized housing of the clothes collectively modularizes a condenser, a compressor, an evaporator and an expansion valve that constitute the heat pump system of the clothes dryer. Not only does the heat pump system is stably mounted in the clothes dryer but also components of the heat pump system can be effectively protected. In addition, the fastening procedures of each component can be unified to simplify an assembling process of the clothes dryer, and thus, the productivity can be improved. Moreover, a structure of an internal flow path of the clothes dryer can be simplified to thus improve efficiency of the heat pump system.
