Description

Technical Field

[0001] This application relates to the field of new energy, and particularly to a liquid-cooled spliced heat exchange component. Background Art

[0002] Existing liquid-cooled heat exchange components are mostly of an integrated plate structure. Although this structure has a certain heat exchange effect, there are some obvious limitations in practical applications. This integrated plate structure has great deficiencies in terms of usage flexibility and is difficult to flexibly adjust the heat exchange area and size according to actual needs. In addition, the number and density of heat exchange channels in different regions are fixed and cannot adapt to scenarios with different heat generation requirements.

[0003] For example, in the practical application of energy storage batteries or energy storage devices, the heat generation is not evenly distributed. There are significant temperature differences in different regions inside the energy storage battery, and different heat exchange effects are required. However, due to its fixed structural design, the existing integrated liquid-cooled heat exchange component cannot be flexibly adjusted according to these different requirements, resulting in low heat exchange efficiency and even potential impact on the performance and lifespan of the energy storage battery due to local overheating.

[0004] In the prior art, these deficiencies of liquid-cooled heat exchange components have attracted the attention of some researchers and engineers. For example, during the heat exchange process of energy storage batteries, due to different heat generation amounts in different regions, the heat exchange requirements are also different. However, the existing liquid-cooled heat exchange components perform poorly in this regard and cannot flexibly adjust the area, size of the heat exchange component, or the number and density of heat exchange channels in different regions. The design of this fixed structure is particularly limited in some application scenarios and cannot meet the diverse needs in practical applications.

[0005] In summary, the existing integrated liquid-cooled heat exchange components have obvious deficiencies in terms of usage flexibility, specifically manifested as the inability to adjust the heat exchange area and size according to actual application needs, and the inability to flexibly configure the number and density of heat exchange channels in different regions. These problems lead to low heat exchange efficiency, cannot effectively meet scenarios with different heat generation requirements, and restrict the application of liquid-cooled heat exchange technology in energy storage devices. Summary of the Utility Model

[0006] The purpose of this application is to at least overcome the deficiencies existing in the prior art and provide a liquid-cooled spliced heat exchange component. This heat exchange component can be flexibly spliced through modular design, and can adjust the area, size of the heat exchange component, and the number and density of heat exchange channels in different regions according to actual needs, thereby improving the heat exchange efficiency and meeting the requirements of different application scenarios.

[0007] To achieve the above object, the present application discloses a liquid-cooled spliced heat exchange component, including a heat exchange module, an intermediate module, and an end module. Among them, multiple heat exchange modules are spliced and cooperated with the intermediate module to form a plate-shaped combination body, and an end module is provided at each end of the plate-shaped combination body; in the plate-shaped combination body, adjacent heat exchange modules are directly spliced or indirectly spliced and cooperated through at least one intermediate module; both the heat exchange module and the intermediate module include a plate body, an I-shaped female groove recessed at one end of the plate body, and an I-shaped convex portion provided at the other end of the plate body and having a shape and size suitable for the female groove; an interface communicating with a heat exchange flow channel is provided in the female groove. Correspondingly, an elastic plug exposed on the convex portion is provided on the convex portion, and the elastic plug is adapted to the interface. When the heat exchange module is cooperated with another heat exchange module or the intermediate module, adjacent elastic plugs are inserted into the interface to form a sealed connection structure; guiding surfaces for the elastic plugs are provided at both open ends of the female groove. Through the guiding surfaces, when the convex portion is horizontally inserted into the female groove, the elastic plug is guided and pressed, and when it reaches the interface position, it relies on elastic recovery and is inserted into the interface in a mating manner to form a sealed interface connection; a heat exchange flow channel connecting the interface and the elastic plug is provided in the heat exchange module; the interface in the intermediate module is directly connected to the elastic plug; the end module is fixedly connected to the heat exchange module or the intermediate module by bolts; a connection socket adapted to the elastic plug or a plug adapted to the interface is provided at one end of the end module, and a coolant connection port is provided at the other end of the end module, and it is connected and cooperated with an external circulating liquid-cooling device through a coolant connection terminal.

[0008] In some embodiments, the heat exchange flow channel is a serpentine flow channel.

[0009] In some embodiments, a guiding silica gel layer is provided on the bottom surface of the heat exchange module.

[0010] In some embodiments, in the plate-shaped combination body, after the heat exchange modules are cooperated with each other or with the intermediate module, they are fixedly locked by bolts.

[0011] In some embodiments, the thickness of the intermediate module is less than that of the heat exchange module, so that the surface / bottom surface of the intermediate module is lower than the surface / bottom surface of the heat exchange module.

[0013] 1.

[0027] like Figures 1 to 5 As shown, this embodiment relates to a liquid-cooled spliced heat exchange assembly, the structure of which includes an end module 1, a heat exchange module 2 and an intermediate module 3.

[0028] In the structural composition, a plurality of heat exchange modules 2 and an intermediate module 3 are spliced and matched to form a plate-shaped assembly, and an end module 1 is respectively provided at both ends of the assembly.

[0029] Furthermore, adjacent heat exchange modules 2 in the plate-shaped assembly can be directly joined or indirectly joined via at least one intermediate module 3. Each heat exchange module 2 and intermediate module 3 includes a plate body 9, an I-shaped female groove 4 recessed at one end of the plate body 9, and an I-shaped raised portion 5 at the other end of the plate body 9. The female groove 4 houses an interface 6 connected to the heat exchange channel, while the raised portion 5 is equipped with an elastic plug 7 that protrudes from the raised portion 5.

[0030] Specifically, when the heat exchange module 2 is mated with the heat exchange module 2 or the intermediate module 3, the adjacent elastic plugs 7 are inserted into the interfaces 6, forming a sealed connection structure. The openings at both ends of the female groove 4 are provided with guide surfaces 8 for the elastic plugs 7. Through these guide surfaces 8, when the protrusion 5 is horizontally inserted into the female groove 4, the elastic plugs 7 are guided and pressed upward, making them flush with the bottom of the female groove 4, thereby allowing the protrusion 5 to be smoothly inserted into the female groove 4. When it reaches the interface 6 position, it relies on elastic recovery and plugs into the interface 6 to form a sealed interface connection.

[0031] To meet the need of heat exchange, a heat exchange flow path connecting the connection interface 6 and the elastic plug 7 is provided in the heat exchange module 2, and the interface 6 and the elastic plug 7 in the intermediate module 3 are directly connected. The end module 1 and the heat exchange module 2 or the intermediate module 3 are connected by bolt locking. One end of the end module 1 is provided with a connection socket that cooperates with the elastic plug 7 or a plug that cooperates with the interface 6, and the other end is provided with a connection port connected to the cooling end. Specifically, the liquid-cooled spliced heat exchange component in this embodiment realizes flexible splicing and combination through modular design.

[0032] In this embodiment, each of the heat exchange module 2, the intermediate module 3, and the end module 1 is made of high-strength aluminum alloy material and its surface is anodized to enhance the corrosion resistance and heat dissipation effect. One end of the plate body 9 is provided with an I-shaped female groove 4, and the other end is provided with an I-shaped protrusion 5 that cooperates with the female groove 4. An interface 6 communicating with the heat exchange flow path is provided inside the female groove 4, and an elastic plug 7 exposed on the protrusion 5 is provided on the protrusion 5. The guiding surface 8 at both open ends of the female groove 4 is designed such that when the protrusion 5 is inserted into the female groove 4, the elastic plug 7 can be accurately docked into the interface 6 to ensure a sealed connection. The heat exchange flow path in the heat exchange module 2 is designed in a serpentine shape, increasing the flow path and time of the coolant and improving the heat exchange efficiency.

[0033] In actual operation, a serpentine heat exchange flow path is provided in the I-shaped female groove 4 of the heat exchange module 2, and the coolant circulates through the serpentine flow path to achieve efficient heat exchange. The guiding surfaces 8 are designed at both open ends of the recessed female groove 4. When the protrusion 5 is inserted into the female groove 4, the elastic plug 7 is gradually pressed to the position of the interface 6 under the guidance of the guiding surface 8 and relies on its own elastic recovery to achieve a tight docking with the interface 6, thus ensuring a leak-free flow of the fluid. The design of the intermediate module 3 takes into account reducing the actual heat exchange load of the coolant. The thickness of the intermediate module 3 is slightly smaller than that of the heat exchange module 2, making its surface or bottom surface lower than the surface or bottom surface of the heat exchange module 2, which can prevent the intermediate module 3 from participating in heat exchange and reduce the actual heat exchange load of the coolant. The intermediate module 3 and the heat exchange module 2 are connected by bolt locking, ensuring the stability and structural strength of the combination.

[0034] In this embodiment, the end module 1 is used to connect the heat exchange component to an external liquid-cooling system. One end of the end module 1 is provided with a connection socket that cooperates with the elastic plug 7 or a plug that cooperates with the interface 6, and the other end is provided with a coolant connection port, which is connected and cooperates with an external circulating liquid-cooling device through a coolant connection terminal. The design of the end module 1 enables it to adapt to different types of coolant connection ports, enhancing the applicability of the system.

[0035] The liquid-cooled spliced heat exchange component of this embodiment achieves extremely high flexibility in use through a modular structure. Users can select different numbers and types of modules for splicing according to specific application requirements to adjust the size and heat exchange capacity of the heat exchange component. Whether it is a large-scale device or a small-scale device, it can be flexibly adjusted through modular design to meet various cooling requirements. By adjusting the cooperation relationship between the heat exchange module 2 and the intermediate module 3, the heat exchange module 2 can be arranged where there are batteries or where heat dissipation is required, reducing the length of the internal heat exchange flow path, reducing flow resistance, and improving application efficiency. Moreover, this system has good versatility and can simultaneously meet the heat dissipation requirements of large-size battery modules and small-size battery modules, greatly reducing the mold opening cost and production cost of heat dissipation components in the development of new energy storage products.

[0036] The design principle of this embodiment aims to achieve flexibility and efficient thermal management through a modular structure. The splicing connection method between each module ensures the sealing and reliability of the system, and the serpentine flow path design in the heat exchange module 2 further improves the heat exchange efficiency. The thickness design of the intermediate module 3 can prevent the intermediate module 3 from participating in heat exchange, effectively reducing the heat exchange load of the coolant and enhancing the overall performance of the system.

[0037] In specific application scenarios, the liquid-cooled spliced heat exchange component can be widely used in the liquid-cooled temperature control of energy storage battery modules. In the cooling system of energy storage batteries, due to the large difference in heat generation in different regions, the modular design allows for flexible adjustment of the number and position of the heat exchange module 2 according to specific heat generation requirements, ensuring that each region can be fully cooled, extending the battery life and improving system stability. For example, in an energy storage battery module, a large amount of heat is generated during the charging and discharging process of battery cells. By adjusting the layout of the heat exchange module 2, the heat can be effectively conducted into the coolant, ensuring the temperature uniformity and safety of the battery module.

[0038] In summary, the liquid-cooled spliced heat exchange component of this embodiment significantly improves the heat exchange efficiency and system stability through modular design and efficient sealed connection, and has broad application prospects. Its flexible splicing feature enables it to adapt to various complex application scenarios of energy storage battery modules and provide a better thermal management solution.
