Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 5 The evaporator tube positioning structure of the present evaporator includes an inner barrel 40 and an outer barrel 50.

An evaporator tube 60 is arranged in the barrel partition cavity 30. A front end cover plate 70 and a rear end cover plate 80 are provided on the inner barrel 40 or the outer barrel 50. The front end cover plate 70 and the rear end cover plate 80 are respectively located at the front and rear positions of the barrel partition cavity 30. The evaporator tube 60 is spirally wound in the barrel partition cavity 30. The front end of the spirally wound section 100 of the evaporator tube 60 is positioned on the front end cover plate 70, and the rear end is positioned on the rear end cover plate 80.

[0024] In this embodiment, the front end cover plate 70 is used to position the front end of the spirally wound section 100, and the rear end cover plate 80 is used to position the rear end of the spirally wound section 100, so as to avoid the problem of displacement of the front and rear ends of the evaporator tube 60 after spiral winding. That is, after the evaporator tube 60 is assembled, the front and rear ends of the spirally wound section 100 are positioned by the front end cover plate 70 and the rear end cover plate 80 respectively, thereby ensuring that the evaporator tube 60 can be firmly assembled in the barrel compartment cavity 30, thereby improving the position assembly stability of the evaporator tube 60.

[0025] The front end cover plate 70 and the rear end cover plate 80 are respectively arranged at the front and rear ends of the inner barrel 40. The outer diameters of the front end cover plate 70 and the rear end cover plate 80 are respectively larger than the outer diameters of the front and rear ends of the inner barrel 40. The evaporating tube 60 is spirally wound on the outer wall of the inner barrel 40, and the front and rear ends of the spirally wound section 100 are respectively positioned on the front end cover plate 70 and the rear end cover plate 80.

[0026] In this embodiment, the front cover plate 70 and the rear cover plate 80 are respectively fixed to the front and rear ends of the inner barrel 40 by fasteners or clips, and the front cover plate 70 and the rear cover plate 80 can also be fixed to the front and rear ends of the inner barrel 40 by another intermediate component. In addition, since the outer diameters of the front cover plate 70 and the rear cover plate 80 are both larger than the outer diameters of the front and rear ends of the inner barrel 40, a height difference is formed between the front cover plate 70 and the front end of the inner barrel 40, and between the rear cover plate 80 and the rear end of the inner barrel 40. When the evaporator tube 60 is assembled, the front and rear ends of the spirally wound section 100 can be positioned on the front cover plate 70 and the rear cover plate 80, respectively.

[0027] During assembly, the rear end cover plate 80 is first set at the rear end of the inner barrel 40, and then the evaporator tube 60 is spirally wound into shape, and then sleeved on the outer wall of the inner barrel 40, so that the rear end of the spirally wound section 100 is positioned on the rear end cover plate 80, and finally the front end cover plate 70 is set at the front end of the inner barrel 40, and the front end of the spirally wound section 100 is positioned.

In addition, the positioning cooperation of the rear plate positioning groove 80.3 is utilized to position the bending position of the outer bending section 300 on the rear plate positioning groove 80.3, which not only effectively positions the bending position of the outer bending section 300, but also avoids the problem of breakage caused by excessive bending of the outer bending section 300. That is, it can effectively improve the assembly stability of the evaporator tube 60, avoid its displacement problem after assembly, and at the same time avoid damage to the evaporator tube 60.

[0033] A separation cylinder 40.1 is provided inside the inner barrel 40, and the separation cylinder 40.1 separates a first inner barrel cavity 40.2 and a second inner barrel cavity 40.3 which are independent of each other.
