Abstract
A heat exchanger comprising header pipes, flat tubes extending between the header pipes and fin units extending between the flat tubes is disclosed. The header pipes include a plurality of holes on one side thereof for accepting the flat tubes. On the opposite side of the header pipes is at least one slit in which a partition plate is inserted. During the formation of the header pipe, a pair of projections are formed on the ends of the slit. After the partition plate is inserted into the header pipe, the projections are bent until they engage the partition plate thereby fixedly securing the partition plate within the header pipe.

A refrigerant circuit comprising:
- a compressor;
- a condenser disposed downstream of said compressor;
- an accumulator disposed downstream of said condenser;
- an expansion element downstream of said condenser;
- and
- an evaporator disposed downstream of said expansion element;
- said condenser further comprising;
- a first header pipe;
- a second header pipe spaced from said first header pipe;
- a heat exchanging region formed between said header pipes;
- a slit formed in at least one of said header pipes;
- a partition plate inserted in said slit;
- and
- at least one projection extending from said at least one of said header pipes, for fixedly securing said partition plate within said slit.
A header pipe for use in a heat exchanger, said header comprising;
- at least one slit formed in a side surface of said header pipe;
- a partition plate inserted in said at least one slit;
- at least one projection extending from said at least one of said header pipes, for fixedly securing said partition plate within said at least one slit.
