The first matching area 101 includes a first sub-matching area 1011 and a second sub-matching area 1012. The first sub-matching area 1011 is arranged at the first end of the first sub-evaporator 201, and the second sub-matching area 1012 is arranged at the first end of the second sub-evaporator 202. The first sub-matching area 1012 is provided with a plurality of first through holes 1013. The heat exchange tubes of the first sub-evaporator 201 are inserted into the first through holes 1013 and limited in the first through holes 1013, so as to realize the first sub-matching area 1011 limiting the first sub-evaporator 201. The second sub-matching area 1012 is provided with a plurality of first through holes 1013 , and the heat exchange tubes of the first sub-evaporator 201 are inserted into and confined in the first through holes 1013 , so as to achieve the limitation of the second sub-evaporator 202 by the second sub-matching area 1012 .

[0054] The first sub-evaporator 201 and the second sub-evaporator 202 are connected, and there is a folding angle between the first sub-evaporator 201 and the second sub-evaporator 202, so that the first sub-evaporator 201 and the second sub-evaporator 202 can be connected more compactly. The first sub-matching area 1011 and the second sub-matching area 1012 are connected and a folding angle is formed at the connection, so that the first sub-matching area 1011 corresponds to the first sub-evaporator 1012, and the second sub-matching area 1012 corresponds to the second sub-evaporator 202. Moreover, a folding angle is formed at the connection between the first sub-matching area 1011 and the second sub-matching area 1012, so that the first sub-matching area 1011 and the second sub-matching area 1012 have multi-directional position limiting for the first sub-evaporator 201 and the second sub-evaporator 202, limiting the displacement and misalignment between the first sub-evaporator 201 and the second sub-evaporator 202, optimizing the spatial structure layout of the air conditioner, and enhancing the structural stability of the evaporator assembly and the durability of the assembly.

[0055] When the auxiliary evaporator 30 is arranged on one side of the first sub-evaporator 201 in the width direction, the second matching area 102 is arranged on one side of the first sub-matching area 1011 in the width direction; when the auxiliary evaporator 30 is arranged on one side of the second sub-evaporator 202 in the width direction, the second matching area 102 is arranged on one side of the second sub-matching area 1012 in the width direction.

The second end plate 50 is suitable for being installed on the second end of the auxiliary evaporator 30, and the second end plate 50 includes a connecting fitting portion 503. The connecting portion is correspondingly connected to the connecting fitting portion 503 to connect the first end plate 40 and the second end plate 50, thereby fixing the second end plate 50.

[0073] Optionally, the connection portion of the evaporator assembly is detachably connected to the connection fitting portion 503 .

[0074] The detachable connection, on the one hand, can make it possible not to install the second end plate 50 when the air conditioner does not include the auxiliary evaporator 30, that is, when the second end plate 50 is not needed; on the other hand, it can facilitate the later maintenance of the first end plate 40 and the second end plate 50.

The first end of the auxiliary evaporator 30 is fixed to the first end of the main evaporator 20 and the tube plate, and the second end of the auxiliary evaporator 30 is fixed to the second end of the main evaporator 20 by using the first end plate 40 and the second end plate 50 respectively, so that both ends of the auxiliary evaporator 30 in the length direction are limited to limit the misalignment and movement of the auxiliary evaporator 30 relative to the main evaporator 20 in various directions.

[0080] When the auxiliary evaporator 30 is arranged on one side of the first sub-evaporator 201 in the width direction, the second end plate 50 is arranged on one side of the first sub-end plate 401 in the width direction; when the auxiliary evaporator 30 is arranged on one side of the second sub-evaporator 202 in the width direction, the second end plate 50 is arranged on one side of the second sub-end plate 402 in the width direction.

At this time, the main evaporator is produced normally first. Since the auxiliary evaporator has an irregular structure, the existing production equipment cannot realize the auxiliary evaporator tube threading and tube expansion work. Therefore, in this application, the auxiliary evaporator is fixed by the second end plate alone, and then the tube threading and tube expansion work are carried out, and finally the whole is fixed to the tube plate.

[0083] The present application also provides an air conditioner, comprising an evaporator assembly as described in any one of the above embodiments.

[0084] The air conditioner provided in the present application includes the evaporator assembly as described in any one of the above embodiments, and thus has all the beneficial effects of the evaporator assembly as described in any one of the above embodiments, which will not be described in detail here.

[0085] The air conditioner includes an indoor unit, which includes a housing, an evaporator assembly and a fan. The housing defines an air duct. The evaporator assembly and the fan are both arranged in the air duct. Under the action of the fan, air enters from the air inlet of the air duct, exchanges heat with the evaporator assembly, and then blows out from the air outlet of the air duct.

[0086] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
