Abstract
A heat exchanger and an air conditioning device are provided. The heat exchanger includes a plurality of fins and a plurality of flat pipes arranged in parallel. Each of the plurality of flat pipes includes a first finned region, a second finned region, and a finless region. 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, and a portion of the finless region between the first torsion section and the second torsion section is defined as a connecting section.
