Title: Air conditioning apparatus

Abstract: According to the present invention, an air conditioning apparatus include a case partitioned into a first air passage and a second air passage by partition plates (16-19), a heat exchanger such as a heater core. The heater exchanger is sandwiched between the partition plates. Further, the heat exchanger is formed by laminating tubes and a fin while the fin is disposed in each main air passage formed between tube walls of the tubes. Each end of the partition plates is opposite to each end of the tubes so that the partition plates are parallel to the tubes. In this way, airflows which respectively have passed from the air first and second passages pass through the heat exchanger without being mixed with each other therein. As a result, the separation characteristics of airflows can be improved.
