Description

Technical Field

[0001] This application relates to the field of liquid cooling heat exchange, and particularly to an attached heat conduction module in a three-dimensional liquid cooling heat exchange component. Background Art

[0002] In the prior art, liquid cooling plates are usually used for the thermal management of batteries, and the heat generated by the batteries during operation is removed by flowing coolant through the liquid cooling plates. However, the existing liquid cooling plate designs mainly achieve contact heat exchange with the front or bottom surface of the battery, and the thermal management efficiency is insufficient in some application scenarios.

[0003] The existing contact heat exchange method between the liquid cooling plate and the front or bottom surface of the battery has certain limitations. First, this single-sided or bottom-contact heat exchange method results in a long heat conduction path. The heat conducts from the inside of the battery to the contact surface and then is dissipated through the liquid cooling plate, and the heat conduction efficiency is limited. At the same time, due to the uneven heat distribution in different regions of the battery, a single contact surface cannot effectively cover all high-temperature areas, resulting in local overheating, which affects the performance and lifespan of the battery.

[0004] In addition, there are also some problems in the structural design of the existing liquid cooling plates. The contact between the liquid cooling plate and the battery is not tight enough, and the heat conduction efficiency is low, which makes the cooling effect unsatisfactory. At the same time, the assembly and maintenance of the existing liquid cooling plates also face challenges. Due to the complex pipeline design and the compact installation space, the liquid cooling plate is prone to position deviation during the assembly process, resulting in poor contact and affecting the cooling effect. In addition, after the liquid cooling system operates for a period of time, the liquid cooling plate and the coolant channels may become blocked and accumulate dirt, increasing the maintenance difficulty and cost.

[0005] Therefore, in view of the problem that the existing liquid cooling plates can only achieve contact heat exchange with the front or bottom surface of the battery and the heat conduction efficiency is insufficient, it is of great significance to develop a new attached heat conduction module in a three-dimensional liquid cooling heat exchange component. Summary of the Utility Model

[0006] The purpose of this application is to at least overcome one deficiency existing in the prior art, and provide an attached heat conduction module in a three-dimensional liquid cooling heat exchange component. This attached heat conduction module enables the side surface of the battery to contact the liquid cooling heat exchange plate. Through optimized design, the heat conduction efficiency is improved, ensuring that the heat in each area of the battery can be quickly conducted to the liquid cooling plate and dissipated, thereby enhancing the overall cooling effect.

[0007] To achieve the above object, the present application discloses an attachment heat conduction module in a three-dimensional liquid cooling heat exchange component. The attachment heat conduction module includes a T-shaped body and a T-shaped heat exchange flow channel arranged in the body. Among them, the body has a horizontal section and a vertical section perpendicular to the horizontal section, and both ends of the horizontal section are provided with interfaces; the interface has a guiding surface and at least one sealing rubber ring arranged on the interface surface; a heat-conducting silica gel layer is provided on the lower surface of the horizontal section and the side surface of the vertical section; the heat exchange flow channel has a first section and a second section located in the horizontal section, and a U-shaped section located in the vertical section. Both ends of the U-shaped section are respectively connected to the first section and the second section to form a complete continuous flow channel.

[0008] Further, the vertical section is U-shaped, and the vertical section and the horizontal section cooperate to form a hollow position, and the hollow position is filled with flame-retardant rubber to form a flame-retardant layer.

[0009] Further, a serrated plate is provided at the interface, and the serrated plate is used for disturbing the flow of the heat exchange flow channel.

[0010] Compared with the prior art, the attachment heat conduction module in the three-dimensional liquid cooling heat exchange component realizes the efficient circulation and uniform heat exchange of the coolant through the combination of the T-shaped heat exchange flow channel and the U-shaped section; the heat-conducting silica gel layer significantly improves the heat conduction efficiency; the flame-retardant rubber filled in the hollow position not only enhances the safety of the component, but also enables the heat conduction module to act as a flame-retardant partition in the battery box, improving the fire prevention performance of the system. The serrated plate design at the interface increases the flow disturbance effect in the flow channel, further optimizing the heat exchange performance and ensuring the efficient, stable and safe heat management function of the component in various harsh environments.

[0021] As Figures 1 to 4 shown, this embodiment relates to an attachment heat conduction module in a three-dimensional liquid cooling heat exchange assembly for a battery. This module is designed to closely fit with the surface and side of the battery, so as to achieve efficient three-dimensional heat dissipation. The structure is simple and reasonable, which helps to improve the heat dissipation efficiency and temperature control of the battery.

[0022] In the specific structure of this embodiment, the main structure of the heat conduction module is a T-shaped body 1, which includes a horizontal section 2 and a vertical section 3. The horizontal section 2 is closely attached to the upper surface part of the battery, and the vertical section 3 is closely attached to the side of the battery. Through this design, the heat conduction module can cover the surface and side of the battery at the same time, maximizing the heat dissipation area, so as to achieve three-dimensional heat dissipation. The body 1 is made of a high thermal conductivity material, ensuring the structural stability and good heat dissipation performance.

[0023] Specifically, inside the body 1, there is a T-shaped heat exchange flow channel, which specifically includes a first section 4, a second section 5, and a U-shaped section 6. The first section 4 and the second section 5 extend along both sides of the horizontal section 2 respectively, and the U-shaped section 6 is located inside the vertical section 3. The design purpose of the U-shaped section 6 is to ensure that both side surfaces of the heat conduction module have flow channels, enabling the liquid to conduct sufficient heat exchange on the side of the battery to meet the heat dissipation requirements. The U-shaped section 6 is connected to the first section 4 and the second section 5 to form a continuous fluid channel, allowing the liquid to flow efficiently in the module and conduct heat exchange.

[0024] Furthermore, a plurality of serrated plates are evenly distributed inside the heat exchange flow channel. These serrated plates are used to disturb the flow of the fluid, forming turbulence, thereby significantly improving the heat exchange efficiency. The serrated plates are made of an alloy material with high thermal conductivity and corrosion resistance to ensure its stability and reliability during long-term use.

[0025] In this embodiment, the lower surface of the horizontal section 2 and the side surface of the vertical section 3 of the heat conduction module are both covered with a heat-conducting silicone layer 8 with a thickness of 2 mm. The heat-conducting silicone layer 8 has excellent heat-conducting performance and can quickly conduct the heat on the surface and side of the battery to the fluid in the heat exchange flow channel. In addition, the heat-conducting silicone layer 8 also has a flexible buffering function, which can reduce the mechanical stress between the battery and the heat conduction module, thereby avoiding structural damage caused by stress concentration during long-term use.

[0026] It can be understood that the heat-conducting silicone layer 8 is made of a silicone material with excellent heat-conducting performance and has good heat conductivity and flexibility. Its main function is to improve the heat exchange efficiency of the heat conduction module. Specifically, through its softness and elasticity, the heat-conducting silicone layer makes the contact area between the heat conduction module and the battery or other components to be heat-exchanged larger and the contact closer. This close contact can effectively reduce the thermal resistance, improve the heat conduction efficiency, ensure that the heat is quickly conducted from the battery or other components to the heat exchange module, thereby enhancing the overall heat exchange efficiency. In addition, the flexibility of the silicone material can adapt to the slight deformation between the module and the components to be heat-exchanged, ensuring continuous close fitting and good heat-conducting performance, and further improving the cooling effect and stability of the system.

[0027] Furthermore, at the connection between the vertical section 3 and the horizontal section 2, a hollowed-out area is designed, and a flame-retardant rubber 7 is filled in the hollow to form a flame-retardant layer. The function of the flame-retardant rubber 7 is to provide additional fire protection during the operation of the heat conduction module. Especially in the case of high temperature or battery failure, it can effectively prevent the risk of fire. The design of the flame-retardant layer neither affects the heat dissipation performance of the module nor increases the safety of the module.

[0028] In this embodiment, multiple sealing rubber rings are designed inside the interface 9 of the heat conduction module to ensure the sealing performance when the module is connected to the liquid cooling system, thereby preventing fluid leakage. The sealing rubber rings are made of high-temperature resistant fluororubber material, which can maintain good elasticity and sealing performance in high-temperature environments. In addition, a guiding surface is designed inside the interface 9 to facilitate accurate alignment during the installation process, ensuring the convenience of installation and the reliability of connection.

[0029] Through close cooperation with the battery, the heat conduction module can effectively cover the key heat dissipation areas of the battery. The horizontal section 2 is partially attached to the upper surface of the battery, and the vertical section 3 is closely attached to the side surface of the battery, ensuring a large contact area, which helps to improve the heat dissipation efficiency. The use of the thermal conductive silicone layer 8 further enhances the thermal conductivity, enabling the heat generated by the battery during high-load operation to be quickly transferred to the cooling fluid and achieving efficient heat dissipation through the cooling fluid flowing through the serrated plate. Since the heat exchange channels are evenly distributed in the horizontal section 2 and the vertical section 3, the heat on the entire surface and side of the battery can be evenly dissipated, avoiding the phenomenon of local overheating.

[0030] Analyzed from the working principle, through the design of this heat conduction module, the temperature of the battery can be effectively controlled. The large contact area and optimized heat exchange area ensure that the battery can maintain a stable temperature under high-load working conditions, extend the service life of the battery, and improve its operating efficiency. The overall design of the heat conduction module not only performs excellently in heat dissipation efficiency but also provides reliable guarantees in terms of safety and installation convenience.

[0031] Although the exemplary embodiments of the present application have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present application without substantially departing from the spirit and scope of the present application. Therefore, all changes and modifications are included within the protection scope of the present application defined by the claims. The present application is defined by the appended claims, and equivalents of these claims are also included.
