Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

One embodiment of the present invention is to provide an evaporator, as shown in fig. 1-2, including five fins connected in sequence, i.e., a fin i 1, a fin ii 2, a fin iii 3, a fin iv 4, and a fin v 5; the two ends of each fin are respectively provided with a first end plate group and a second end plate group, each second end plate group comprises a large end plate 9 and a small end plate 10, each small end plate 10 is installed on the side wall of each fin, and the large end plate 9 is connected with the small end plate 10 through screws.

The five fins are connected through the first end plate group and the second end plate group to form a bent structure, each fin is provided with at least one U-shaped tube perforation 6, the five fins are provided with 8U-shaped tubes in total, and the fins can be distributed on the five fins reasonably according to specific conditions during actual design, and the distribution mode provided by the utility model is as follows: 2U-shaped tubes are arranged on the fin I1, 1U-shaped tube is arranged on the fin II 2, 2U-shaped tubes are arranged on the fin III 3, 2U-shaped tubes are arranged on the fin IV 4, and 1U-shaped tube is arranged on the fin V5; the U-shaped tubes are arranged on the fins in a parallel tube penetrating mode, and the parallel tube penetrating mode means that the U-shaped tubes are parallel relative to the plane of the fins.

In order to fix the U-shaped pipe, the first end plate group is provided with positioning holes 7 corresponding to the through holes 6 of the U-shaped pipe, each positioning hole 7 is internally provided with a positioning boss 8, and one end of the U-shaped pipe is buckled in the positioning hole 7 through the positioning boss 8 to fix the U-shaped pipe.

Because the whole volume of air conditioner internal unit is generally fixed, in order to reach and use red copper internal thread U pipe still less, still less evaporimeter fin, adjustment evaporimeter space of buckling, number of times of buckling make air conditioner internal unit possess the effect of higher amount of wind under equal platform, equal fan. The present invention provides one of the following embodiments: the included angle between the fin I1 and the fin II 2 is 147 degrees, the included angle between the fin II 2 and the fin III 3 is 150 degrees, the included angle between the fin IV 4 and the fin III 3 is 102 degrees, the included angle between the fin IV 4 and the fin V5 is 136 degrees, and in actual production, the included angle between the fins is allowed to be changed by +/-2 degrees.
