[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0021] The following describes an embodiment of the utility model based on its overall structure.

[0022] An evaporator for a refrigeration device, such as Figure 1-4 As shown, it includes fins 1, a mounting frame 4 is fixed on the outside of the fins 1, and multiple groups of heat dissipation copper tubes 3 are installed inside the fins 1. The fins 1 cooperate with the heat dissipation copper tubes 3 to complete heat dissipation. A connecting tube 2 is arranged on the top of the heat dissipation copper tube 3. The multiple groups of heat dissipation copper tubes 3 are connected through the connecting tube 2 to achieve circulation;

[0023] The mounting frame 4 fixes the multiple groups of fins 1, and the multiple groups of heat dissipation copper tubes 3 are connected through the provided connecting tubes 2, and the connecting tubes 2 have inlets and outlets.

[0024] It should be noted that the fin 1 can be made of metal aluminum.

[0025] See also Figure 1-3 The interior of the fin 1 is rotatably connected with a connecting shaft 10 through a bearing, the connecting shaft 10 passes through the fin 1 and is rotatably connected thereto, a motor 11 is installed on one side of the mounting frame 4 through a connecting frame, the position of the motor 11 is fixed, and the output end of the motor 11 is connected to the second fan blade 8, and an inner ring 5 is provided on the outer side of the second fan blade 8, and an outer ring 6 is provided on the outer side of the inner ring 5, the first fan blade 7 is fixed on the outer side of the outer ring 6, and a third fan blade 13 is fixed at one end of the connecting shaft 10.

[0026] It can be understood that the motor 11 drives the second fan blade 8 to rotate, and the second fan blade 8 drives the inner ring 5 to rotate. Under the action of the gear 9, the gear 9 rotates, and the outer ring 6 rotates, so that the first fan blade 7, the second fan blade 8 and the third fan blade 13 all rotate to achieve heat dissipation. Figure 1-3 A gear 9 is fixed to one end of the connecting shaft 10, and a limiting groove 12 cooperating with the gear 9 is provided inside the outer ring 6, and the inner wall of the limiting groove 12 and the outer wall of the inner ring 5 are both provided with teeth meshing with the gear 9.

[0027] It should be noted that the setting of the limit groove 12 can limit the outer ring 6 so that it is always meshed with the gear 9. Then, under the action of the teeth, when the inner ring 5 rotates, the gear 9 rotates on itself, and the gear 9 drives the outer ring 6 to rotate, thereby realizing the rotation of multiple sets of fan blades and completing heat dissipation.

[0028] Please pay attention to Figure 1 The directions of the first fan blade 7 and the second fan blade 8 are opposite, and the directions of the first fan blade 7 and the third fan blade 13 are the same.

[0029] It can be understood that when the second fan blade 8 rotates forward, the third fan blade 13 rotates backward, and the first fan blade rotates backward; so when the first fan blade 7 and the second fan blade 8 are in opposite directions, the first fan blade 7 and the third fan blade 13 have the same direction, and the wind direction formed is the same, completing the wind heat dissipation.

[0030] Furthermore, there are multiple groups of heat dissipation copper tubes 3, and the top and bottom ends of the outer sides of the multiple groups of heat dissipation copper tubes 3 are all provided with external threads, and the bottom end of the outer side of the connecting tube 2 is provided with a nut 14 that cooperates with the external threads. It should be noted that, under the action of the mutual cooperation between the internal thread and the external thread, the nut 14 is turned to facilitate the disassembly of the connecting tube 2, and then facilitate the cleaning of the blockage inside the heat dissipation copper tube 3.

[0031] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
