PURPOSE: A heater unit case for an air conditioner of a vehicle is provided to improve the air-conditioning performance of an air conditioner by preventing the vortex of air through a curved part for guiding an air flow path at an opening of a heater unit case. CONSTITUTION: A heater unit case(30) has an opening(31) for flow air discharged through a cooling unit. A heater unit(32) having inlet/outlet pipes(33,34) is mounted under the heater unit case, and discharge ports(35) are formed right on the case. The discharge port is used for discharging heat-exchanged air of the heater unit to an indoor space. The heater unit case has a curved part(36) extended from the opening to the center. The guide part is used as an air guide for sucking air discharged through the cooling unit. The curved part has S-shaped structure for minimizing the flow resistance of air. Thereby, the air-conditioning performance of the air conditioner is improved.
