Abstract

In an air conditioning apparatus, an air conditioning case has an upstream portion defining an air intake port through which air flows into the upstream portion substantially parallel to a core surface of a heat exchanger. The air intake port has a vertical dimension H1 that is smaller than a vertical dimension H2 of the core surface. The upstream portion has an air flow direction changing portion protruding inside of the upstream portion at a position opposite to the core surface above the air intake port. The air flow direction changing portion defines a clearance between the core surface and itself. A part of the air turned upward and further turned substantially parallel to the core surface strikes the air flow direction changing portion and flows toward the core surface through the clearance.
