ABSTRACT:
A multi-layered type heat exchanger for a refrigerant fluid circuit is disclosed which includes a plurality of substantially parallel flat tubes. Each flat tube includes a partition wall for dividing its interior into two fluid passages. A plurality of fin units are disposed between the plurality of flat tubes. A header pipe has a plurality of slits for inserting upper ends of the flat tubes, respectively, and at least one partition wall to divide the interior thereof into at least two chambers. A seal member sealingly closes lower open ends of the flat tubes. Thus, since the height and length of the flat tubes can be easily adjusted, various sizes and designs of heat exchangers can be easily and cost effectively produced.
