Air conditioner device for a vehicle

An air conditioning device for a vehicle, comprising:

• a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the outflow space;
• a blowing unit disposed at the inflow space of the housing and configured to blow air;
• a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air;
• and
• at least one opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports,
• wherein the outflow space of the housing is formed such that a width of a portion connected to the heat exchange space gradually decreases, such that air that has passed through the heat exchange space converges on a center, and another section of the outflow space is curved.
