Technical Field
[0001] This utility model relates to the field of chassis structure combination technology, and more specifically, to a combination structure that is compatible with multiple methods and applicable to multiple environments. Background Technology
[0002] In current applications of chassis cooling structures, traditional designs reveal numerous problems that urgently need to be addressed. Air-cooled and thermally conductive chassis suffer from severe lack of flexibility and adaptability when dealing with complex and diverse external environments. In particular, the commonly used single, integrated design of ruggedized modules not only results in low thermal conductivity, making it difficult to meet the cooling requirements of long-term stable operation, but also limits their applicability to specific, single working environments, failing to achieve cross-environment versatility and significantly restricting the application range of the equipment. Facing customer demands for various outdoor, indoor, and underwater military environments, existing chassis structures are inadequate. This invention addresses this background by developing a combined structure that is compatible with multiple usage methods and adaptable to various complex environments, thereby solving the pain points of existing technologies. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a combined structure that is compatible with multiple methods and applicable to multiple environments, aiming to improve the problem of the existing chassis structure being too simple.
[0004] This utility model is implemented as follows: a combined structure that is compatible with multiple methods and applicable to multiple environments. The combined structure includes heat dissipation fins, an upper cover plate, a pull-out aid, a heat pipe, a cold plate, a front baffle, a locking strip, a PCB board, and a cold plate back plate. The heat dissipation fins, the cold plate, the PCB board, and the cold plate back plate are fixedly connected in sequence. The heat dissipation fins are connected to the upper cover plate. The cold plate has mounting holes corresponding to the locking strip on both sides. The pull-out aid and the front baffle are installed on the front side of the cold plate.
[0005] In a preferred embodiment of this utility model, the cold plate is fixedly mounted on the front side of the PCB board, and the cold plate backplate is fixedly mounted on the back side of the PCB board, thereby mounting the PCB board between the cold plate and the cold plate backplate.
[0006] In the preferred embodiment of this utility model, the cold plate is made of aluminum alloy, and its interior is pre-designed with embedding grooves according to the shape and layout of the heat pipes. Three straight heat pipes and one U-shaped heat pipe (total length 180mm and width 8mm) are respectively embedded in the corresponding embedding grooves. After embedding, a brazing process is used to tightly bond the heat pipes to the cold plate. Then, the upper surface of the cold plate is milled flat. After the heat pipes are embedded, an advanced brazing process is used. After brazing, a high-precision milling machine is used to mill the entire upper surface of the cold plate flat to ensure surface flatness and uniform heat conduction.
[0007] In a preferred embodiment of this utility model, the upper surface edge of the cold plate is provided with a plurality of first threaded holes, and the heat dissipation fin is provided with a through hole at the corresponding position. The through hole and the first threaded hole are screwed together with a first screw to realize the connection between the cold plate and the heat dissipation fin. Before the connection, thermally conductive silicone is evenly applied to the contact surface between the cold plate and the heat dissipation fin. During the screwing process, the thermally conductive silicone fills the gap between the two.
[0008] In a preferred embodiment of this utility model, the heat dissipation fins are fixedly connected to the upper cover plate by a second screw, and the heat dissipation fins are provided with a second threaded hole that mates with the second screw.
[0009] In a preferred embodiment of this invention, mounting ears are provided on both sides of the front end of the cold plate, and mounting holes are provided on corresponding positions on both sides of the front baffle. A third screw is screwed through the mounting holes of the front baffle and into the third threaded hole of the mounting ear to fix the front baffle to the front end of the cold plate. The locking strip is an integral structure. By rotating the top locking screw, the middle locking block is squeezed, squeezed along the outer edge, and slides upward to protrude. The puller is fixedly installed at a specific position on the cold plate, facilitating operation of related components.
[0010] In the preferred embodiment of this utility model, the bending part of the heat pipe is optimized through fluid dynamics simulation, and the wall thickness is differentiated along the length of the pipe. While ensuring structural strength, the flow efficiency of the working fluid inside the heat pipe is further improved, thereby enhancing the heat conduction performance and adapting to the complex heat conduction environment inside the cold plate.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a combined structure compatible with multiple methods and applicable to multiple environments. The combined structure includes a heat dissipation fin 110, a top cover plate 121, a pull-out aid 124, a heat pipe 122, a cold plate 120, a front baffle 125, a locking strip 123, a PCB board 130, and a cold plate back plate 140. The heat dissipation fin 110, the cold plate 120, the PCB board 130, and the cold plate back plate 140 are sequentially fixedly connected. The heat dissipation fin 110 is connected to the top cover plate 121. The cold plate 120 has mounting holes corresponding to the locking strip 123 on both sides. The pull-out aid 124 and the front baffle 125 are installed on the front side of the cold plate 120. The cold plate 120 is fixedly installed on the front side of the PCB board 130, and the cold plate back plate 140 is fixedly installed on the back side of the PCB board 130, thereby installing the PCB board 130 between the cold plate 120 and the cold plate back plate 140.
[0022] In some specific implementation schemes, the cold plate 120 is made of aluminum alloy, and its interior is pre-designed with precise embedding slots according to the shape and layout of the heat pipes 122. Three straight heat pipes 122 and one U-shaped heat pipe 122 (total length 180mm and width 8mm) are respectively embedded in the corresponding embedding slots. After embedding, a brazing process is used to tightly bond the heat pipes 122 to the cold plate 120. Then, the upper surface of the cold plate 120 is milled flat. After the heat pipes 122 are embedded, an advanced vacuum brazing process is used. After brazing, a high-precision milling machine is used to mill the entire upper surface of the cold plate 120 to ensure surface flatness and uniform heat conduction. The brazing and milling of the upper surface of the cold plate 120 after embedding makes the heat pipes 122 and the cold plate 120 tightly bonded, improving the heat conduction efficiency between the two. The milling process ensures the flatness of the upper surface of the cold plate 120, which is conducive to uniform heat transfer, thereby improving the overall heat dissipation effect and ensuring the stability of the equipment during operation.
[0023] In some specific implementations, the upper surface edge of the cold plate 120 is provided with a plurality of first threaded holes, and the heat dissipation fin 110 is provided with a through hole at the corresponding position. The through hole and the first threaded hole are screwed together with a first screw to realize the connection between the cold plate 120 and the heat dissipation fin 110. Before the connection, thermally conductive silicone is evenly applied to the contact surface between the cold plate 120 and the heat dissipation fin 110. During the screwing process, the thermally conductive silicone fills the gap between the two. The use of thermally conductive silicone can greatly reduce the thermal resistance between the two and promote the efficient conduction of heat to the heat dissipation fin 110, thereby effectively improving the heat dissipation performance of the entire combined structure.
[0024] In some specific implementations, the heat dissipation fin 110 is fixedly connected to the upper cover plate 121 by a second screw, and the heat dissipation fin 110 is provided with a second threaded hole that mates with the second screw.
[0025] In some specific implementations, mounting ears are provided on both sides of the front end of the cold plate 120, and mounting holes are provided on the corresponding positions of the front baffle 125. The front baffle 125 is fixed to the front end of the cold plate 120 by passing a third screw through the mounting hole of the front baffle 125 and screwing it into the third threaded hole of the mounting ear of the cold plate 120. The locking strip 123 is an integral structure. By rotating the top locking screw, the two locking blocks in the middle are squeezed and squeezed along the outer edge, and slide upward to protrude, thereby reducing the gaps on the upper and lower sides of the installation position and achieving the locking effect. This further improves the adaptability of the combined structure in different chassis layouts and environments and the protection performance of internal components.
[0026] In some specific implementation schemes, the bending section of the heat pipe 122 is optimized through fluid dynamics simulation, and the wall thickness is differentiated along the pipe length. While ensuring structural strength, this further improves the flow efficiency of the working fluid inside the heat pipe 122, thereby enhancing the heat conduction performance and adapting to the complex heat conduction environment inside the cold plate 120.
[0027] Working Principle: During operation, the generated heat is first transferred to the cold plate 120, which is tightly connected to the PCB board 130. The cold plate 120 is made of aluminum alloy and has pre-designed embedding slots to accommodate the heat pipes 122. Three straight 1888mm heat pipes and one U-shaped heat pipe 122 are embedded and then brazed to the cold plate 120 for tight bonding, allowing heat to be rapidly conducted to the heat pipes 122. The curved sections of the heat pipes 122 are optimized using fluid dynamics simulation, with differentiated wall thicknesses to ensure efficient internal fluid flow and rapid heat dissipation. The cold plate 120 and the heat dissipation fins 110 are screwed together with long screws, and the contact surfaces are filled with thermally conductive silicone, allowing heat to be conducted to the heat dissipation fins 110. When the chassis is air-cooled and the 120 cooling plate module does not need to be attached to the wall, the top panel of the heat dissipation fin 110 can be removed to increase the contact area between the heat dissipation fin 110 and the airflow, thereby enhancing the air-cooling effect. If it needs to be installed against the wall, the top panel of the heat dissipation fin 110 can be installed, and heat conduction can be achieved by adhering to the inner wall of the chassis to achieve efficient heat dissipation.
[0028] Structural Cooperation Principle: Cold plates 120 and cold plate back plates 140 are mounted on both sides of the PCB board 130, forming a stable protective structure. The cold plate 120 serves as the main structure, with the front baffle 125 fixed to the front of the frame by a third screw, providing initial protection for the internal components. One end of the locking strip 123 is mounted on a pivot seat inside the frame via a pivot, while the locking block at the other end can engage with a corresponding slot, securing the internal components from both directions and ensuring their stability under different environments. A puller 124 is fixedly installed at a specific position on the cold plate 120 for easy operation of related components. The close cooperation of all components in the overall structure ensures stable operation of the combined structure in various environments.
[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
