Description

Air conditioner Technical Field The application relates to the technical field of air treatment, in particular to an air conditioner. Background The heat exchanger is an important part of the heat exchange cycle of the air conditioner, and comprises a plurality of heat exchange pipes and fins, wherein the refrigerant flowing through the heat exchange pipes exchanges heat with the outside air. The fins may increase the heat exchange area between the refrigerant and the outside air in the heat exchange tube. In general, when refrigerant is introduced into the plurality of heat exchange tubes through the header pipe, the refrigerant may be unevenly distributed into the plurality of heat exchange tubes due to inclination of the liquid refrigerant caused by gravity and inertial force, and thus it is necessary to design a distribution structure in the header pipe to improve the distribution of the refrigerant into the heat exchange tubes. Specifically, the header has a distribution structure for uniformly distributing the refrigerant and a distribution structure for guiding the separated refrigerant to the heat exchange tube, and the distribution structure are relatively dense and complex, thereby increasing the manufacturing difficulty of the header. Disclosure of utility model The application provides an air conditioner, which is convenient for processing and assembling a collecting pipe by designing the collecting pipe.
