Description

Technical Field

[0001] This utility model relates to the technical field of plate-tube evaporators, and in particular to an assembly structure for a plate-tube evaporator. Background Technology

[0002] Plate-tube evaporators are an important component of the refrigerator's cooling system, typically consisting of pipes and aluminum plates. Existing plate-tube evaporators mainly employ an assembly structure using bent aluminum plates for positioning; this involves bending the aluminum plate and inserting it into corresponding fixing points within the refrigerator liner to secure the evaporator. However, this assembly method has the following technical drawbacks:

[0003] Poor fixation reliability: The structure of the bent aluminum plate relies on its own mechanical springback characteristics to maintain the limit, which makes it difficult to guarantee sufficient fixing force. This may cause the evaporator to loosen during use and affect the cooling effect.

[0004] Limited assembly precision: Due to dimensional tolerances in the bending of aluminum plates, improper installation may occur during the assembly process, which in turn affects the contact quality between the evaporator and the refrigerator liner, reducing heat exchange efficiency.

[0005] Low production operability: When using the aluminum plate bending structure, the assembler needs to reach into the box to install it, which is not only inconvenient to operate, but also increases the assembly time and labor costs, affecting production efficiency.

[0006] To address the aforementioned problems, this utility model proposes an improved assembly structure for plate-tube evaporators, thereby enhancing fixing reliability, assembly accuracy, and production operability. Utility Model Content

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0039] Example 1

[0040] Reference Figures 1-6 This is the first embodiment of the present invention, which provides an assembly structure for a plate-tube evaporator, comprising:

[0041] Plate-tube evaporator assembly 100: Composed of pipes 101 and aluminum plate 102. Pipes 101 are channels for refrigerant flow, and aluminum plate 102 is used to improve heat transfer efficiency. Pipes 101 are fixed to aluminum plate 102 and are limited and fixed by pipe clips 102a to ensure pipe stability.

[0042] Container liner assembly 200: The container liner 200 is part of the refrigerator liner. It has grooves 201 on both sides of its inner wall. The grooves 201 extend vertically along the inner wall of the container liner 200 to accommodate the edge of the aluminum plate 102, so that the aluminum plate 102 can be stably inserted into and fit against the refrigerator body.

[0043] Fixing component 300: includes symmetrically arranged aluminum plate clips 301. The aluminum plate clips 301 have a positioning structure that matches the corners of the aluminum plate 102. By inserting the aluminum plate clips 301 into the groove 201 and matching them with the aluminum plate 102, the plate tube evaporator assembly 100 is fixed in the left-right and front-back directions to prevent shaking and improve overall stability.

[0044] In this embodiment, the initial positioning is provided by the groove 201 to accurately place the aluminum plate 102, and the final limiting and fixing is achieved by the aluminum plate buckle 301, which ensures the stability of the evaporator and improves assembly efficiency and reliability.

[0045] Example 2

[0046] Reference Figure 1 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that in this embodiment, the pipe 101 is preferably made of copper or aluminum and is fixed on the aluminum plate 102 in a serpentine arrangement to increase the heat exchange area.

[0047] This embodiment ensures a stable installation of the evaporator while improving heat exchange efficiency and enhancing the overall performance of the refrigeration system.

[0048] Example 3

[0049] Reference Figure 1 This is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that in this embodiment, the pipe clip 102a and the aluminum plate 102 are manufactured by an integral stamping process, which avoids additional parts assembly and improves production efficiency and stability.

[0050] Multiple pipe clamps 102a are spaced apart along the length of the pipe 101 and are alternately arranged on the left and right sides along the axial direction of the pipe 101 to provide uniform limiting effect and prevent the pipe 101 from becoming loose or displaced.

[0051] This embodiment optimizes the structural design of the evaporator, improves the fixing reliability of the pipeline 101, simplifies the manufacturing process, and reduces production costs.

[0052] Example 4

[0053] Reference Figures 2-6 This is the fourth embodiment of the present invention. The difference between this embodiment and the first embodiment is that the width of the groove 201 and the thickness of the aluminum plate 102 form an interference fit, that is, the groove 201 is slightly smaller than the thickness of the aluminum plate 102, so that the aluminum plate 102 can fit tightly when inserted, thereby improving the fixation stability.

[0054] In addition, the depth of the groove 201 is preferably set to 8-12mm, with 10mm being the optimal depth, to ensure that the aluminum plate 102 has sufficient limiting effect after insertion, while avoiding excessive depth that would cause assembly difficulties.

[0055] This design further enhances assembly reliability, enabling precise positioning of aluminum plate 102 and improving product consistency.

[0056] Example 5

[0057] Reference Figures 3-5 This is the fifth embodiment of the present invention. The difference between this embodiment and the first embodiment is that in this embodiment, the aluminum plate buckle 301 is composed of an installation part 301a and an aluminum clip part 301b. The aluminum clip part 301b has an L-shaped cross section and includes a horizontally extending top pressing part 301b-1 and a vertically extending side pressing part 301b-2, which respectively cover the upper surface and side surface of the corner of the aluminum plate 102, thereby achieving multi-directional fixation.

[0058] In addition, the inner side of the aluminum clip 301b is provided with anti-slip texture (not shown in the figure), which forms a friction fit when in contact with the surface of the aluminum plate 102, improving the fixing effect and preventing the aluminum plate 102 from loosening during long-term use.

[0059] This embodiment adopts an L-shaped aluminum plate buckle structure and anti-slip texture design to make the evaporator more securely fixed, improve assembly quality and long-term stability.

[0060] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
