ABSTRACT:
In a heat exchanger formed by laminating tube elements alternately with fins over a plurality of levels, a plurality of beads are formed in each of tube elements provided with intake/outlet portions in the areas where the tank portions change to a passage portion. The width of these beads are set to be larger than the beads in other tube elements so as to constrict the passage cross section. In addition, the areas of the communicating holes formed in tank portions away from the intake/outlet portion through which the heat exchanging medium flows in are made smaller than the areas of the communicating holes formed in tank portions near the intake/outlet portion. The centers of the communicating holes in the tank portions further away from the intake/outlet portion are located further downward than the centers of the communicating holes in the tank portions provided closer to the intake/outlet portion. The distribution of the heat exchanging medium is made more consistent to reduce inconsistency in the temperature among individual tube elements in order to achieve good heat exchange.
