Vehicle air conditioner

A method of providing a vehicle air conditioner, the method comprising:

• providing an air conditioning device connected to a blower device such that the air conditioning device receives air supplied from the blower device;
• providing a heat exchange core in the air conditioning device having an inlet surface and an outlet surface that are parallel with a flow direction of the air supplied from the blower device;
• providing a partition wall that divides the heat exchange core into a first core part and a second core part, such that the air supplied from the blower device is distributed and supplied to the first core part and the second core part;
• providing a blower fan with a rotational axis perpendicular to the inlet surface of the heat exchange core;
• providing an adjustment door installed upstream of the partition wall to adjust a ratio of air blown from the blower fan into the first core part and the second core part;
• and
• providing an air guide in a connection portion between the blower device and the air conditioning device, which separates air discharged from a discharge port of the blower device, opened to one side relative to the rotational axis of the blower fan, into two parts and supplies both parts to the adjustment door, wherein the first core part is located between the blower device and the second core part along an imaginary straight line that follows the flow direction of the air supplied from the blower device to the air conditioning device.
