A bent heat exchanger includes a first manifold, a second manifold, and a plurality of flat tubes each being configured to communicate the first manifold with the second manifold, and fins between the flat tubes; wherein the flat tube includes a first straight section, a second straight section and a bent section connecting the first straight section with the second straight section. The bent section includes the first twisted section connected to the first straight section, the second twisted section connected to the second straight section, and the connecting section connecting the first twisted section with the second twisted section, and the connecting section of the flat tube has a substantially flat shape or a flat arc shape. In this way, the height of the bent heat exchanger can be reduced, which facilitates the installation and improves the heat exchange performance of the heat exchanger.

Bent heat exchanger and method for bending the heat exchanger

An air conditioning system comprises a compressor (), an outdoor heat exchanger (), a first heat exchanger (), a second heat exchanger () and at least two throttling devices, wherein the outdoor heat exchanger is a micro-passage heat exchanger and comprises a first inlet (), a second inlet (), an outlet (), a distributing pipe (), a collecting pipe (), a flat pipe (), a fin () and a distributor () which is located in the distributing pipe () and used for distributing a working medium, and a distribution small hole () is provided in the distributor (); and the first inlet () is in direct communication with a distributing cavity () of the distributing pipe (), while the second inlet () is in communication with the distributing cavity () through the distributing small hole () in the distributor ().
