Abstract
A heat exchanger and an air conditioner are provided. The heat exchanger includes fins and flat pipes arranged in parallel. Each of the flat pipes includes a first finned region, a second finned region, and a finless region. The first finned region is the second finned region via the finless region. The fins are provided both between adjacent two first finned regions and adjacent two second finned regions. An end of the finless region connected to the first finned region is twisted and defined as a first torsion section, the other end of the finless region connected to the second finned region is twisted and defined as a second torsion section.
