[0003] In existing technologies, the heat exchange efficiency of heat exchangers depends on the design of the fins. Since the metal materials that affect thermal conductivity are limited by current materials science, designing the fins to improve heat exchange is the preferred approach. Summary of the Invention

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a modular heat exchange structure for a water-cooled cold source type air-water chiller unit, comprising:

[0031] Example 1

[0032] This embodiment aims to provide a modular heat exchange structure, which mainly includes a mounting plate 1, multiple finned plates 2, and serpentine cold pipes 3 (composed of continuously bent metal pipes). Among them, the mounting plate 1 serves as the core supporting component, and has multiple equidistant rectangular slots 11 on it, which lay the foundation for airflow channels.

[0033] The finned plate 2 is preferably made of aluminum sheet, which has excellent thermal conductivity and machinability. Multiple finned plates 2 are equidistantly and vertically mounted on the mounting plate 1. Each finned plate 2 is designed with a multi-faceted structure, its body passing through rectangular slots 11 on the mounting plate 1 and extending to both sides of the mounting plate 1. Specifically, the portion extending to one side of the mounting plate 1 (defined as the air inlet side) is the first extension 21, and the portion extending to the other side of the mounting plate 1 (defined as the refrigerant side) is the second extension 22. The rectangular slots 11 are located within the internal space of these finned plates 2, allowing airflow to pass through the slots and fully contact the fins.

[0034] The serpentine cooling pipes 3 serve as refrigerant channels, distributed at a certain angle and passing through the second extensions 22 of multiple finned plates 2. This inclined design effectively increases the effective length and uniformity of the cooling pipes within the finned group.

[0035] In summary, by designing the finned plate 2 as a multi-faceted structure penetrating the mounting plate 1, the first extension 21 and the second extension 22 together constitute a large heat dissipation surface area. The inclined serpentine cooling pipe 3 is tightly integrated with the second extension 22, ensuring efficient heat transfer between the refrigerant and the fins. When hot air flows through the channel formed by the rectangular perforations 11 and the first extension 21, the heat is rapidly absorbed and conducted to the second extension 22, and then carried away by the refrigerant flowing through the serpentine cooling pipe 3, thus achieving modular and efficient heat exchange. This compact structure is particularly suitable for the modular design and assembly of air-water chiller units.

[0036] Example 2

[0037] Please see Figures 2-3 This embodiment further optimizes the structure based on Embodiment 1 to improve airflow disturbance and heat exchange efficiency.

[0038] In this embodiment, the key improvement lies in the provision of extension plates 12 extending in opposite directions on the inner wall of the rectangular slot 11. These extension plates 12 are preferably distributed on both sides of the long side of the rectangular slot 11, acting as guide vanes extending into the airflow channel. In summary, the added extension plates 12 significantly alter the airflow field through the rectangular slot 11. They can disrupt the stable laminar boundary layer, induce vortices and stronger turbulence in the airflow, thereby thinning the static air layer (thermal boundary layer) between the air and the surface of the fin (first extension 21), greatly enhancing the convective heat transfer process.

[0039] Example 3

[0040] Please see Figure 4 and Figure 5 This embodiment provides a specific and optimized topology of the finned plate 2, demonstrating how to maximize heat exchange area and structural stability through complex geometry.

[0041] In this embodiment, the first extension 21 is specifically defined by its shape as two symmetrically distributed first vertical portions 211. The two first vertical portions 211 are connected by a vertical portion 212, one end of which is fixedly connected to the end of one of the first vertical portions 211. Subsequently, the other end of the vertical portion 212 is fixedly connected to the end of the other first vertical portion 211 by a first U-shaped connecting portion 213 distributed away from the mounting plate 1. This structure allows the first extension 21 to form a robust three-dimensional frame with a large surface area.

[0042] Furthermore, the vertical portion 212 is positioned corresponding to the rectangular slot 11, and it has multiple rectangular slots 2121 linearly distributed along the vertical direction. These rectangular slots 2121, while ensuring structural strength, promote the penetration and mixing of airflow inside the fins, reducing flow dead zones.

[0043] The second extension 22 is structurally divided into a second U-shaped portion 221 and a third U-shaped portion 222. One end of the second U-shaped portion 221 is fixedly connected to the end of a first vertical portion 211 near the mounting plate 1, and one end of the third U-shaped portion 222 is fixedly connected to the corresponding end of another first vertical portion 211. The rectangular slots 11 are distributed precisely between the second U-shaped portion 221 and the third U-shaped portion 222.

[0044] As an important preferred option, the port diameter of the second U-shaped section 221 is three times the port diameter of the third U-shaped section 222. This asymmetrical design allows for a more rational allocation of space during the installation of the serpentine cooling pipe 3, ensuring good contact between the cooling pipe and the fins at different locations, and adapting to changes in heat exchange requirements caused by temperature variations during refrigerant flow.

[0045] Furthermore, the spacing between two adjacent fin plates 2 is designed to be less than the length of the short side of the rectangular slot 11. This dimensional relationship ensures that the airflow must fully interact with the densely arranged fins, avoiding airflow "short-circuiting" and maximizing the heat exchange capacity of every part of the air flowing through the rectangular slot 11.

[0046] In summary, through the three-dimensional frame structure of the first extension 21 and the rectangular holes 2121 on the vertical portion 212, the heat exchange area is maximized and the airflow organization is optimized while ensuring mechanical strength. The second extension 22 adopts a U-shaped section design of different sizes, providing optimal wrapping and support for the serpentine cold pipe 3, ensuring the uniformity of thermal resistance across the entire heat exchange surface. The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
