1. An air conditioner, comprising:
a plurality of flat tubes configured to circulate a gas-liquid two-phase refrigerant, a flow direction of the gas-liquid two-phase refrigerant in a first part of the plurality of flat tubes being opposite to a flow direction of the gas-liquid two-phase refrigerant in a second part of the plurality of flat tubes;
a first header disposed at an end of the plurality of flat tubes, the first header including:
a first chamber communicating with the first part of flat tubes; and
a second chamber communicating with the second part of flat tubes;
a second header disposed at another opposite end of the plurality of flat tubes, the second header including:
a header body communicating with the first part of flat tubes; and
at least one flow disturbing portion disposed in the header body and configured to disturb a flow of the gas-liquid two-phase refrigerant in the header body;
a third header disposed at the another opposite end of the plurality of flat tubes and communicating with the second part of flat tubes;
a connecting pipe communicating with the header body of the second header and the third header;
a separator configured to separate the gas-liquid two-phase refrigerant into a gas-phase refrigerant and a liquid-phase refrigerant;
a gas distribution pipe group communicating with the separator and the second chamber and configured to circulate the gas-phase refrigerant; and
a liquid distribution pipe group communicating with the separator and the second chamber and configured to circulate the liquid-phase refrigerant.
