Description

Technical Field

[0001] The invention relates to the technical field of heat conducting plates, in particular to a heat conducting plate and a production method thereof. Background Art

[0002] Thermal conductive plates are a type of highly efficient heat conduction material, widely used in electronic product heat dissipation, industrial heating equipment, automotive thermal management systems, and home appliance manufacturing. With its excellent thermal conductivity, it can quickly transfer heat from the heat source to the heat dissipation device, effectively preventing performance degradation or equipment damage caused by overheating. Thermal conductive plates are usually made of metals or composite materials with high thermal conductivity, such as aluminum, copper alloys, or graphene composite materials. These materials not only have excellent thermal conductivity, but also have good mechanical strength and processing properties. In electronic products, thermal conductive plates are widely used in heat dissipation solutions for core components such as CPUs and GPUs to ensure that the equipment can maintain stable performance under high-intensity operation. At the same time, in the industrial field, thermal conductive plates are also core components of equipment such as heat exchangers and heating plates, which are of great significance for improving production efficiency and ensuring equipment safety.

[0003] A Chinese patent with announcement number CN220750893U discloses a combined aluminum profile heat-conducting plate, including a water-cooling plate, a frame, an assembly frame and a bottom plate, wherein the assembly frame is fixedly installed on the top of the bottom plate, and two groups of mounting holes are provided on the front and back of the assembly frame, a return spring is fixedly installed inside the mounting hole, and a locking pin is fixedly installed at one end of the return spring, a frame is installed on the outside of the assembly frame through the locking pin and the locking hole, a water-cooling plate is embedded and installed on the top of the frame, and a water-cooling pipe is embedded and installed inside the water-cooling plate.

[0004] However, during the actual use of the heat conducting plate in the above-mentioned prior art, we found that there are still some shortcomings. For example, during the assembly of the traditional heat conducting plate, after the frame and the assembly frame are installed, the water cooling plate needs to be installed on the frame with a large number of screws, which increases the difficulty of production and assembly of the heat conducting plate to a certain extent. Secondly, in the subsequent inspection and maintenance of the heat conducting plate, the frame and the assembly frame need to be disassembled, and when disassembling, it is necessary to press multiple spring lock pins at the same time to open it. Therefore, it often requires the cooperation of multiple people to complete it, which is not very convenient to implement. Moreover, the aluminum heat conducting plate is installed in the assembly frame, and the heat conducting square plate on the assembly frame is at the lower end of the assembly frame. At the same time, the water cooling plate is on the inner side of the upper end of the frame. Since the heat conducting structures are relatively dispersed and not compact enough, the overall heat conducting effect of the heat conducting plate will be affected. Summary of the invention

[0014] A method for producing a heat conducting plate comprises the following steps:

[0015] Step 1: Select appropriate materials according to the requirements of the heat conducting plate, and then cut and grind the selected materials according to the design requirements, and then perform surface treatment on the heat conducting plate materials, and then perform precision processing through CNC machine tools and punching equipment to obtain the assembled parts of the heat conducting plate;

[0016] Step 2: Clean the processed heat conducting plate parts, count the required parts according to the production and assembly requirements, and then assemble them according to the process;

[0017] Step 3: During the production and assembly of the heat conducting plate parts, firstly, the lower end of the lower heat conducting shell is inserted into the inner side of the upper end of the heat conducting substrate. During the insertion process, the heat conducting column with the heat conducting ridge at the lower end of the lower heat conducting shell is synchronously adapted and plugged into the heat conducting groove with the ridge groove on the inner side of the upper end of the heat conducting substrate;

[0018] Step 4: After the lower heat-conducting shell is installed, place the water-cooling plate with the water-cooling pipe inside the upper end of the lower heat-conducting shell, and then plug the upper heat-conducting shell and the upper end of the water-cooling plate together. During the insertion process, the pipe joint at the end of the water-cooling pipe in the water-cooling plate is passed through the upper heat-conducting shell. At the same time, the lower end of the upper heat-conducting shell and the upper end of the lower heat-conducting shell are also plugged together.

[0019] Step 5: glue the elastic pressure pad to the lower end of the connecting plate shell, and then insert the lower port of the connecting plate shell along the upper end of the upper heat-conducting shell. During the insertion process, the card sleeve on the outside of the connecting plate shell squeezes the inclined surface of the card block extending from the inner side of the connecting block sleeve groove, and the pull plate connected to the card block compresses the spring sleeved on the outer side of the pull column in the installation cavity. When the card sleeve is inserted into the sleeve groove, and the card sleeve sleeve mouth corresponds to the card-in end of the card block connected to the pull plate, the spring resets and pushes the card block connected to the pull plate to clamp and fix the card sleeve of the connecting plate shell;

[0020] Step 6: After the connection plate shell and the heat-conducting substrate are installed, the heat sink at the upper end of the upper heat-conducting shell will penetrate the connection plate shell, and then, right-angle fixing blocks are installed around the bottom of the heat-conducting substrate to obtain the heat-conducting plate;

[0021] Step 7. After the assembled heat conducting plate is subjected to assembly quality inspection and thermal conductivity test, the product can be packaged.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, in the present invention, the heat-conducting substrate is made of copper material, and the lower heat-conducting shell with heat-conducting columns, the upper heat-conducting shell, the water-cooling plate and the heat dissipation plate are all made of aluminum material. Due to the superior thermal conductivity of copper, efficient heat conduction can be performed after installation, and the heat is connected through a plurality of plum blossom-shaped heat-conducting columns and the heat-conducting grooves on the heat-conducting substrate. By expanding the contact surface between the two, the heat-conducting substrate can quickly conduct the heat to the lower heat-conducting shell, and the water-cooling plate between the lower heat-conducting shell and the upper heat-conducting shell is connected to the cold water pipe through a pipe joint at one end, and the pipe joint at the other end is connected to the hot water pipe. After the cold water is introduced, the cold water flows along the tortuous periphery of the cold water pipe. The heat transferred from the outside of the cold water plate can be taken away, and part of the heat will be conducted to the upper heat-conducting shell. At the same time, the upper heat-conducting shell can further improve the effect of heat conduction and heat dissipation through the heat dissipation plate at the upper end. The heat-conducting plate in this scheme adopts a combination of copper and aluminum. Copper has a high thermal conductivity and can quickly transfer heat. Although aluminum has a slightly lower thermal conductivity, it has a small density and a large heat capacity, which is conducive to the absorption and dissipation of heat. Combining the two can give full play to their respective advantages and achieve efficient heat transfer and dissipation. In addition, the structure between the heat conduction elements in the heat-conducting plate is more compact, and the thermal conductivity efficiency is also better.

[0024] Secondly, in the present invention, the connecting plate shell is plugged into the upper end of the upper heat-conducting shell. During the insertion process, the card sleeve on the outside of the connecting plate shell squeezes the inclined surface of the card block extending from the inner side of the connecting block sleeve groove, and the pull plate connected to the card block compresses the spring sleeved on the outer side of the pull column in the installation cavity. When the card sleeve is inserted into the sleeve groove, and the card sleeve sleeve mouth corresponds to the card-in end of the card block connected to the pull plate, the spring resets and pushes the card block connected to the pull plate to clamp and fix the card sleeve of the connecting plate shell. When the interior of the heat-conducting plate is subsequently maintained, the connecting plate shell and the heat-conducting substrate need to be disassembled. During the process, by pulling the pull rod, the pull column connected to the pull rod drives the block connected to the pull plate to separate from the clamping sleeve on the connecting plate shell, and then after the pull rod is limited by the limiting mechanism on the heat-conducting base plate, the connecting plate shell can be quickly removed from the heat-conducting base plate, so that the heat-conducting base plate can be quickly disassembled, maintained and used. The entire heat-conducting plate only needs to be connected at one place to complete the production and assembly of the entire heat-conducting plate part structure, which has higher assembly production efficiency, lower production and assembly difficulty coefficient, and more convenient subsequent maintenance.

[0025] Thirdly, in the present invention, by flipping the limit rod, the shaft rod on the limit rod rotates at the concave block. When the limit rod rotates to correspond to the limit groove at the convex part of the pull rod, the pull rod can be loosened so that the spherical end of the limit rod can be inserted into the limit groove to limit the pull rod. When the pull rod is limited, the connecting plate shell can be directly removed from the thermal conductive substrate, so that the thermal conductive substrate and the connecting plate shell can be quickly disassembled and used conveniently.

[0048] Step 4: After the lower heat-conducting shell 9 is installed, the water-cooling plate 8 with the water-cooling tube 13 is placed inside the upper end of the lower heat-conducting shell 9, and then the upper heat-conducting shell 7 is plugged into the upper end of the water-cooling plate 8. During the insertion process, the pipe joint 20 at the end of the water-cooling tube 13 in the water-cooling plate 8 is passed through the upper heat-conducting shell 7, and at the same time, the lower end of the upper heat-conducting shell 7 and the upper end of the lower heat-conducting shell 9 are also plugged into each other and joined;

[0049] Step 5, glue the elastic pressure pad 23 to the lower end of the connecting plate shell 2, and then insert the lower port of the connecting plate shell 2 along the upper end of the upper heat-conducting shell 7. During the insertion process, the card sleeve 12 on the outside of the connecting plate shell 2 squeezes the inclined surface of the card block 401 extending from the inner side of the sleeve groove 24 of the connecting block 3, and the pull plate 406 connected to the card block 401 compresses the spring 405 sleeved on the outer side of the pull column 404 in the installation cavity 403. When the card sleeve 12 is inserted into the sleeve groove 24, and the sleeve opening of the card sleeve 12 corresponds to the card-in end of the card block 401 connected to the pull plate 406, the spring 405 resets and pushes the card block 401 connected to the pull plate 406 to clamp and fix the card sleeve 12 of the connecting plate shell 2;

[0050] Step 6: After the connection plate shell 2 and the heat-conducting substrate 1 are installed, the heat sink 6 at the upper end of the upper heat-conducting shell 7 will penetrate the connection plate shell 2. Then, the right-angle fixing blocks 17 are installed around the bottom of the heat-conducting substrate 1 to obtain the heat-conducting plate;

[0051] Step 7. After the assembled heat conducting plate is subjected to assembly quality inspection and thermal conductivity test, the product can be packaged.

[0052] The working principle of the present invention is: when the heat conducting plate is produced and assembled, first, the heat conducting substrate 1, the lower heat conducting shell 9, the water cooling plate 8, the upper heat conducting shell 7 and the connecting plate shell 2 are plugged in sequence, and then the connecting plate shell 2 is plugged into the upper end of the upper heat conducting shell 7. During the insertion process, the clamping sleeve 12 on the outside of the connecting plate shell 2 squeezes the inclined surface of the clamping block 401 extending from the inner side of the sleeve groove 24 of the connecting block 3, and the pulling plate 406 connected to the clamping block 401 compresses the spring 405 sleeved on the outer side of the pulling column 404 in the installation cavity 403. When the clamping sleeve 12 is inserted into the sleeve groove 24, and the sleeve mouth of the clamping sleeve 12 corresponds to the clamping end of the clamping block 401 connected to the pulling plate 406, the spring 405 is reset and pushes the clamping block 401 connected to the pulling plate 406 to clamp the connecting plate shell 2. The sleeve 12 is engaged and fixed, and when the interior of the heat conducting plate is subsequently maintained, the connecting plate shell 2 and the heat conducting substrate 1 need to be disassembled. During the disassembly process, by pulling the pull rod 402, the pull column 404 connected to the pull rod 402 drives the block 401 connected to the pull plate 406 to separate from the clamping sleeve 12 on the connecting plate shell 2, and then the limiting rod 504 is turned over to make the shaft rod 502 on the limiting rod 504 rotate at the concave block 501. When the limiting rod 504 rotates to correspond to the limiting groove 26 at the convex part of the pull rod 402, the pull rod 402 can be loosened so that the spherical end of the limiting rod 504 can be inserted into the limiting groove 26, so that the pull rod 402 can be limited. When the pull rod 402 is limited, the connecting plate shell 2 can be directly removed from the heat conducting substrate 1;

[0053] During use, after the heat conducting plate is installed on the equipment that needs heat dissipation, the heat conducting substrate 1 can perform efficient heat conduction after installation due to the superior thermal conductivity of copper material, and the heat is connected through a number of plum blossom-shaped heat conducting columns 10 and the heat conducting grooves 11 on the heat conducting substrate 1. By expanding the contact surface between the two, the heat conducting substrate 1 can quickly conduct the heat to the lower heat conducting shell 9, and the water cooling plate 8 between the lower heat conducting shell 9 and the upper heat conducting shell 7 is connected to the cold water pipe through the pipe joint 20 at one end, and the pipe joint 20 at the other end is connected to the hot water pipe. After the cold water is passed in, the cold water can take away the heat transferred from the outside of the cold water plate along the tortuous circumference of the cold water pipe, and part of the heat will be conducted to the upper heat conducting shell 7. At the same time, the upper heat conducting shell 7 can further improve the effect of heat conduction and heat dissipation through the heat dissipation plate 6 at the upper end.
