Abstract

A heat exchanger (1) including a pair of header pipes (2,3) and a plurality of heat transfer tubes (4) extending between and placing the header pipes (2,3) in communication and extending in parallel to each other to form a parallel-flow type heat exchanger core (13). The heat exchanger core (13) is bent, so that relative to a center portion of the core, at least one header pipe (3) is offset in the direction of air flow across the heat exchanger (1). The offset disposition of a larger header pipe may be achieved without increasing a tube insertion length into the header pipe or the reduction or elimination of liquid storing and moisture reducing unit contained in the header pipe.
