Abstract
A double-row bent heat exchanger is provided. The heat exchanger includes: a first header and a second header; flat tubes each divided into a first straight segment connected to the first header, a second straight segment connected to the second header and a twisted segment connected between the first straight segment and the second straight segment, along a length direction of the flat tube; and fins disposed between adjacent first straight segments and between adjacent second straight segments. The flat tube is bent at the twisted segment around a first bending axis (L) to provide a first bending portion. The first header and the second header are bent around at least one second bending axis (K) to provide at least one second bending portion.
