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 provides an evaporator, as shown in fig. 1-2, including three fins connected in sequence, where the three fins include a fin i 1, a fin ii 2, and a fin iii 3, the fin i 1, the fin ii 2, and the fin iii 3 are connected between a first end plate group and a second end plate group in a bending manner, each fin is provided with at least one U-shaped tube through hole 4, the second end plate group includes an end plate i 7, an end plate ii 8, and an end plate iii 9, the end plate i 7, the end plate ii 8, the end plate iii 9, the fins i 1, the fins ii 2, and the fins iii 3 are respectively connected in a one-to-one correspondence manner, and the end plate i 7, the end plate ii 8, and the end plate iii 9 are fixedly connected by screws.

In the utility model, seven U-shaped tubes are arranged on the fin I1, the fin II 2 and the fin III 3, and can be reasonably distributed on three fins according to specific conditions during actual design, two U-shaped tubes are arranged on the fin I1, two U-shaped tubes are arranged on the fin II 2, and three U-shaped tubes are arranged on the fin III 3, wherein the U-shaped tubes are arranged on the fins in a parallel tube penetrating manner, and the parallel tube penetrating means that the U-shaped tubes are parallel to the plane of the fins.

In order to fix the U-shaped pipe conveniently, the first end plate group is provided with positioning holes 5 corresponding to the through holes 4 of the U-shaped pipe, each positioning hole 5 is internally provided with a positioning boss 6, and one end of the U-shaped pipe is buckled in the positioning hole 5 through the positioning boss 6 to realize the fixation of the U-shaped pipe.
