Disclosed is a heat pump system for a vehicle. The heat pump system for the vehicle comprises a cooling unit which is connected to a cooling line and circulates cooling water passing through a radiator and a reservoir tank, and an air conditioner which is connected to a refrigerant line to control the cooling and heating of an inside of the vehicle. An electric power control unit (EPCU), a motor, and an on board charger (OBC) are successively cooled through the cooling water on the cooling line between the water pump and the radiator. The cooling line connecting the motor and the OBC further comprises a chiller which exchanges heat and the cooling water of the refrigerant line of the air conditioner. |
