Description

Technical Field

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

[0002] The evaporator is one of the core components of a freezer's refrigeration system. Its function is to vaporize low-temperature, low-pressure liquid refrigerant within the evaporator, absorbing heat from the surrounding environment to achieve a cooling effect inside the freezer. It is typically made of copper or aluminum tubing and equipped with heat exchange fins to increase the heat exchange area and improve refrigeration efficiency. The evaporator is usually installed on the inner wall of the freezer or at the back of the freezer compartment, distributing cold air evenly to the stored items through forced or natural convection. Its performance directly affects the freezer's cooling speed, energy consumption, and temperature uniformity.

[0003] Existing evaporators are typically installed using a mounting bracket on the freezer, which secures the evaporator and greatly ensures its stability. However, this method limits the size of the evaporator, making installation inconvenient and preventing positional adjustments. Therefore, a new freezer evaporator is proposed. Utility Model Content

[0004] To address the aforementioned problems, a refrigerator evaporator is provided. When the first threaded rod is rotated, it moves horizontally through the threaded engagement with the first threaded hole. Simultaneously, the first threaded rod moves along the central axis of the first threaded hole, driving the abutment plate to gradually approach the compressor until the abutment plate makes tight contact with the compressor. This clamps the compressor with the abutment plate, solving the problem of inconvenient compressor installation in refrigerator evaporators.

[0005] To address the existing technical problems, this application provides a freezer evaporator, including heat dissipation fins, a limiting mechanism disposed beside the heat dissipation fins, a hoisting mechanism disposed on the top of the heat dissipation fins, and a compressor disposed at the bottom of the heat dissipation fins. The bottom of the compressor is provided with a fixing mechanism, which includes a base fixed to the freezer. The top of the base is provided with a boss for supporting the compressor. The upper end of the boss is symmetrically fixed with longitudinally arranged baffles, and one side of the baffle is horizontally provided with a first threaded hole. One side of the baffle is provided with an abutment plate that can move horizontally and clamp the compressor. A first threaded rod is rotatably provided on one side of the abutment plate. The first threaded rod is installed through a first threaded hole, and the first threaded hole and the first threaded rod are threadedly engaged.

[0006] As one technical solution of this application, a limiting hole is also provided on the baffle; A limit rod is horizontally fixed on one side of the abutment plate. The limit rod is installed through the limit hole, and the limit hole and the limit rod are slidably engaged.

[0007] As one technical solution of this application, the heat dissipation fins are provided with mounting slots on both sides for easy installation; The limiting mechanism includes a fixed base fixed on the freezer, a movable frame that can move horizontally is provided on one side of the fixed base, and a slot that can be adapted to the slot is opened on the top of one side of the movable frame, and the slot is installed in the slot.

[0008] As one technical solution of this application, a second threaded hole is horizontally provided on one side of the fixing base; A rotatable second threaded rod is horizontally mounted on one side of the mobile frame. The second threaded rod is installed in a second threaded hole, and the second threaded rod is threadedly engaged with the second threaded hole.

[0009] As one technical solution of this application, the bottom of the mobile frame is horizontally fixed with a limiting plate, and the two sides of the limiting plate are in movable contact with the inner side of the fixed seat.

[0010] As one technical solution of this application, the hoisting mechanism includes a fixing block fixed to the top of the heat sink fins, and a third threaded rod is fixed to the top of the fixing block; The hoisting mechanism also includes a sleeve fixed to the freezer. A nut is rotatably installed at the bottom end of the sleeve. A third threaded rod passes through the nut and extends into the sleeve. The nut and the third threaded rod are threadedly engaged.

[0011] The advantages of this utility model application compared to the prior art are: 1. This application achieves horizontal movement by rotating the first threaded rod, which utilizes the threaded engagement with the first threaded hole. Simultaneously, the first threaded rod moves along the central axis of the first threaded hole, driving the abutment plate to gradually approach the compressor until the abutment plate makes tight contact with the compressor. This clamps the compressor with the abutment plate, solving the problem of inconvenient compressor installation in refrigerator evaporators.

[0012] 2. This application utilizes a slot on the top of one side of the movable frame, into which a mounting slot is installed, allowing the slot and mounting slot to cooperate and secure the heat dissipation fins. By rotating the second threaded rod, it engages with the second threaded hole to achieve horizontal movement. Simultaneously, the movement of the second threaded rod electrically moves the movable frame to adjust the distance between it and the heat dissipation fins, enabling the limiting mechanism to meet the installation requirements of heat dissipation fins of different sizes.

[0013] 3. This application uses a nut to rotate along the central axis of the sleeve. As the nut rotates, it drives a third threaded rod that is also in contact with it to move longitudinally. This causes the third threaded rod to drive a fixed block, which in turn adjusts the height of the heat dissipation fins. Attached Figure Description

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] See Figures 1-7 As shown, a refrigerator evaporator includes heat dissipation fins 1, a limiting mechanism 3 disposed beside the heat dissipation fins 1, a hoisting mechanism 4 disposed on the top of the heat dissipation fins 1, and a compressor 13 disposed at the bottom of the heat dissipation fins 1. The bottom of the compressor 13 is provided with a fixing mechanism 2, which includes a base 21 fixed on the refrigerator. The top of the base 21 is provided with a boss 22 for supporting the compressor 13. The upper end of the boss 22 is symmetrically fixed with a longitudinally arranged baffle 23. A first threaded hole 24 is horizontally opened on one side of the baffle 23. A stop plate 26 that can move horizontally and clamp the compressor 13 is provided on one side of the baffle 23. A first threaded rod 27 is rotatably provided on one side of the stop plate 26. The first threaded rod 27 is installed through the first threaded hole 24, and the first threaded hole 24 is threadedly engaged with the first threaded rod 27.

[0024] When the first threaded rod 27 is rotated, it moves horizontally using the threaded engagement with the first threaded hole 24. At this time, the first threaded rod 27 moves along the central axis of the first threaded hole 24, driving the abutment plate 26 to gradually approach the compressor 13 until the abutment plate 26 is in close contact with the compressor 13. This clamps the compressor 13 with the abutment plate 26, solving the problem of inconvenient installation of the compressor 13 in the freezer evaporator.

[0025] See Figure 2 As shown, a limiting hole 25 is also provided on the baffle 23; A limiting rod 28 is horizontally fixed on one side of the abutment plate 26. The limiting rod 28 is installed through the limiting hole 25, and the limiting hole 25 is slidably engaged with the limiting rod 28.

[0026] To ensure the stability of the abutment plate 26, a limiting rod 28 is horizontally fixed on one side of the abutment plate 26. When the abutment plate 26 moves, the abutment plate 26 will drive the limiting rod 28 to move along the central axis of the limiting hole 25, so that the limiting hole 25 and the limiting rod 28 cooperate to limit the abutment plate 26, effectively avoiding the problem of displacement of the abutment plate 26 during movement.

[0027] See Figure 3 , Figure 4 and Figure 5 As shown, the heat dissipation fins 1 have mounting slots 10 on both sides for easy installation; The limiting mechanism 3 includes a fixed base 31 fixed on the freezer. A movable frame 32 that can move horizontally is provided on one side of the fixed base 31. A slot 322 that can be adapted to the slot 10 is opened on the top of one side of the movable frame 32. The slot 10 is installed in the slot 322.

[0028] By opening a slot 322 on the top of one side of the mobile frame 32, and then installing the mounting slot 10 in the slot 322, the slot 322 and the mounting slot 10 cooperate with each other to fix the heat dissipation fins 1.

[0029] See Figure 3 , Figure 4 and Figure 5 As shown, a second threaded hole 311 is horizontally provided on one side of the fixing base 31; A rotatable second threaded rod 323 is horizontally mounted on one side of the movable frame 32. The second threaded rod 323 is installed in the second threaded hole 311 and is threadedly engaged with the second threaded hole 311.

[0030] When the second threaded rod 323 is rotated, the second threaded rod 323 cooperates with the second threaded hole 311 to achieve horizontal movement. While the second threaded rod 323 moves, the electric moving frame 32 moves to adjust the distance between itself and the heat dissipation fins 1, so that the limiting mechanism 3 can meet the installation requirements of heat dissipation fins 1 of different sizes.

[0031] See Figure 3 , Figure 4 and Figure 5 As shown, a limiting plate 321 is horizontally fixed at the bottom of the movable frame 32, and the two sides of the limiting plate 321 are in contact with the inner side of the fixed seat 31.

[0032] When the movable frame 32 moves, it will drive the limiting plate 321 to move horizontally. When the limiting plate 321 moves, both sides of the limiting plate 321 move synchronously along the inner wall of the fixed seat 31. The limiting plate 321 and the second threaded hole 311 cooperate to limit the movable frame 32, effectively preventing the movable frame 32 from rotating axially, thereby ensuring the stability of the movable frame 32.

[0033] See Figure 6 and Figure 7 As shown, the hoisting mechanism 4 includes a fixing block 43 fixed to the top of the heat dissipation fins 1, and a third threaded rod 44 is fixed to the top of the fixing block 43; The hoisting mechanism 4 also includes a sleeve 41 fixed on the freezer. A nut 42 is rotatably provided at the bottom end of the sleeve 41. A third threaded rod 44 passes through the nut 42 and extends into the sleeve 41. The nut 42 and the third threaded rod 44 are threadedly engaged.

[0034] When the nut 42 is rotated, the nut 42 will rotate along the central axis of the sleeve 41. At the same time, the rotation of the nut 42 will drive the third threaded rod 44, which is in conjunction with it, to move longitudinally. This causes the third threaded rod 44 to drive the fixing block 43, so that the fixing block 43 can adjust the height of the heat dissipation fins 1.

[0035] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
