Description

Technical Field

[0001] This utility model relates to the field of refrigerator evaporator fin technology, specifically a louvered refrigerator evaporator fin. Background Technology

[0002] In a refrigerator's refrigeration system, the evaporator fins are a key heat exchange component, and their performance directly affects the refrigerator's refrigeration efficiency and energy consumption.

[0003] Traditional refrigerator evaporator fins typically employ a fixed structure, with no adjustable angle or spacing, making it difficult to adapt to varying heat exchange requirements under different operating conditions. For example, when ambient temperature changes or refrigerator load varies, fixed-structure fins cannot achieve optimal heat exchange, leading to reduced cooling efficiency and increased energy consumption. Furthermore, fixed-structure fins are inconvenient to clean and maintain, easily accumulating dust and dirt, which negatively impacts heat exchange performance. Therefore, developing a louvered type refrigerator evaporator fin that effectively solves these problems is of significant practical importance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a louvered type refrigerator evaporator fin, which solves the problem that traditional refrigerator evaporator fins are usually fixed structures, and the angle and spacing of the fins cannot be adjusted, making it difficult to adapt to the heat exchange requirements under different operating conditions. When the ambient temperature changes or the refrigerator load varies, the fixed structure fins cannot achieve the best heat exchange effect, resulting in reduced cooling efficiency and increased energy consumption.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] This utility model discloses a refrigerator evaporator fin of the louver type.

[0030] Example 1: According to the appendix Figure 1-3 As shown, the device includes a finned unit 1 and a drive unit 2 disposed on its side. The finned unit 1 is mounted on the evaporator body 3. The finned unit 1 and the drive unit 2 are linked to form a louver structure. The finned unit 1 includes:

[0031] Fin body 11, multiple fin bodies 11 are provided and the multiple fin bodies 11 are equally spaced, and a through opening 111 is provided on the fin body 11.

[0032] A rotating shaft 13 is fixedly connected to the side of the fin body 11;

[0033] The drive unit 2 is connected to a rotating shaft 13 on one side of multiple fin bodies 11. The drive unit 2 is used to adjust the tilt angle of the fin bodies 11.

[0034] Furthermore, the finned unit 1 also includes a fixing plate 12, which is fixedly connected to the opening 111. The fixing plate 12 is used to increase the contact area between the finned body 11 and the evaporator body 3. The fixing plate 12 increases the contact area between the finned body 11 and the evaporator body 3, thereby increasing the heat dissipation area of ​​the finned body 11.

[0035] Example 2: According to the appendix Figure 1-3 As shown, the device includes a finned unit 1 and a drive unit 2 disposed on its side. The finned unit 1 is mounted on the evaporator body 3. The finned unit 1 and the drive unit 2 are linked to form a louver structure. The finned unit 1 includes:

[0036] The fin body 11 is provided in multiple ways and is equidistant from each other. The fin body 11 is provided with a through-hole 111, which facilitates the rotation of the fin body 11 and avoids friction between the fin body 11 and the evaporator body 3 during the rotation process, thereby increasing the service life of the fin body 11.

[0037] A rotating shaft 13 is fixedly connected to the side of the fin body 11;

[0038] The drive unit 2 is connected to a rotating shaft 13 on one side of multiple fin bodies 11. The drive unit 2 is used to adjust the tilt angle of the fin bodies 11. The drive unit 2 can simultaneously drive multiple fin bodies 11 to rotate in the same direction, flexibly adjusting the tilt angle of the fin bodies 11. This allows for optimization of the contact area between the fins and air and the airflow path according to different operating conditions, improving heat exchange efficiency, reducing refrigerator energy consumption, and extending the refrigerator's lifespan. The adjustable fin tilt angle makes cleaning more convenient, allowing for more thorough removal of dust and dirt from the fin surface, maintaining good heat exchange performance, and reducing the decrease in heat exchange efficiency caused by dust accumulation.

[0039] Furthermore, the drive unit 2 includes:

[0040] 21 throttles;

[0041] Rotating rod 22, the top end of rotating rod 22 is fixedly connected to throttle handle 21;

[0042] The first bevel gear 23 is fixedly connected to the bottom end of the rotating rod 22;

[0043] The second bevel gear 24 meshes with the first bevel gear 23.

[0044] Furthermore, the second bevel gear 24 is fixedly connected to one of the rotating shafts 13. When it is necessary to adjust the tilt angle of the fin body 11, the user turns the handle 21, which drives the rotating rod 22 to rotate on the evaporator body 3. The first bevel gear 23 at the bottom of the rotating rod 22 rotates accordingly. Since the first bevel gear 23 is meshed with the second bevel gear 24, the second bevel gear 24 also begins to rotate. The second bevel gear 24 is fixedly connected to one of the rotating shafts 13, so the rotating shaft 13 begins to rotate.

[0045] Furthermore, the drive unit 2 also includes:

[0046] The transmission wheel 25 is provided in multiple ways and is fixedly sleeved on the rotating shaft 13.

[0047] A drive belt 26 is connected to multiple drive pulleys 25. Each rotating shaft 13 is fixedly fitted with a drive pulley 25, and these multiple drive pulleys 25 are connected via the drive belt 26. When one rotating shaft 13 rotates, the linkage between the drive pulley 25 and the drive belt 26 drives the other rotating shafts 13 to rotate synchronously. The rotating shaft 13 is fixedly connected to the fin body 11, and the rotation of the rotating shaft 13 drives the fin body 11 to rotate, thereby adjusting the tilt angle of the fin body 11. Users can adjust the fin body 11 to a suitable tilt angle by rotating the handle 21 according to actual needs to optimize the heat exchange performance of the refrigerator evaporator. Throughout the process, the rotating shaft 13 is rotatably connected to the evaporator body 3, ensuring smooth rotation of the fin body 11.

[0048] Furthermore, the rotating rod 22 is rotatably connected to the evaporator body 3.

[0049] Furthermore, the rotating shaft 13 is rotatably connected to the evaporator body 3.
