Description

Technical Field

[0001] This utility model relates to the field of thermally conductive composite phase change element technology, specifically a heat-conducting composite phase change element that is resistant to insertion and removal. Background Technology

[0002] Thermally conductive composite phase change element is an intelligent thermal management material that combines phase change material with high thermal conductivity filler. It achieves temperature regulation through the synergistic effect of phase change heat absorption and efficient thermal conduction. By introducing high thermal conductivity filler, the heat diffusion efficiency is greatly improved, achieving rapid heat dissipation and uniform temperature distribution. During the phase change process, it absorbs / releases a large amount of latent heat, stabilizes the temperature within a specific temperature range, effectively buffers thermal shock, and regulates temperature fluctuations.

[0003] When using the aforementioned thermally conductive composite phase change element, it needs to be inserted at the required heat-conducting position to achieve temperature control. However, during the insertion and removal process, the pins at the bottom of the thermally conductive composite phase change element are easily damaged, making it difficult to remove the pins at the bottom as well. This makes it inconvenient to insert and remove the thermally conductive composite phase change element. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat-conducting composite phase change element that is resistant to insertion and removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-conducting composite phase change element resistant to insertion and removal, comprising a heat-conducting plate, heat-conducting pillars, heat-conducting pins, locking holes, and a heat-conducting interface material, characterized in that: the top end of the heat-conducting plate is provided with heat-conducting pillars for heat dissipation, and the heat-conducting pillars are evenly distributed at the top end of the heat-conducting plate; the end of the heat-conducting plate away from the heat-conducting pillars is provided with heat-conducting pins for insertion and positioning; the heat-conducting pins are symmetrically distributed at the bottom end of the heat-conducting plate; locking holes for connection are provided at both ends of the heat-conducting plate; a heat-conducting interface material is provided on the side of the bottom end of the heat-conducting plate near the heat-conducting pins; fixing pillars are provided on both sides of the heat-conducting plate, and the fixing pillars are symmetrically distributed on both sides of the heat-conducting plate; and handles are sleeved on the surface of the fixing pillars.

[0006] As mentioned above, the handles are symmetrically distributed on both sides of the heat-conducting plate, and the shape of the handles matches the heat-conducting plate.

[0007] As described above, a U-shaped seat is provided at one end of the heat-conducting plate near the fixed column, an adjustment plate is provided inside the U-shaped seat, and a displacement slider that is slidably connected to the U-shaped seat is provided at the bottom end of the adjustment plate.

[0008] As described above, a first limiting spring connected to the U-shaped seat is provided on one side of the adjusting plate, and the first limiting spring is symmetrically distributed on one side of the adjusting plate. A trapezoidal tooth for limiting the movement of the handle is provided on the side of the adjusting plate away from the first limiting spring.

[0009] As described above, the heat-conducting pins are provided with an installation plate that is connected to the bottom of the heat-conducting plate, and the installation plate has a cavity inside.

[0010] As described above, the cavity is provided with a limiting block connected to the heat-conducting pin. The limiting block is shaped like a "T". Guide rods connected to the cavity pass through both ends of the limiting block.

[0011] As described above, a second limiting spring is connected between one side of the limiting block and the cavity, and a locking groove matching the limiting block is opened inside the heat-conducting pin.

[0012] Compared with existing technologies, this heat-conducting composite phase change element with plug-in resistance has the following advantages: 1. When insertion and removal are required, the handle can be pulled upwards to rotate along the fixed post. Similarly, the handle on the other side of the heat-conducting plate can be rotated and removed simultaneously. At this time, the two handles can be placed vertically. Then, the two handles can be pulled upwards simultaneously to move the heat-conducting plate evenly upwards, avoiding deviation when manually pulling the heat-conducting plate upwards. Furthermore, the vertical handles make pulling the plate more convenient and stable. Therefore, when using the heat-conducting composite phase change element, it has a better insertion and removal resistance effect, avoiding deformation and damage caused by deviation during insertion and removal.

[0013] Second, during the insertion and removal process, since the heat-conducting pins are easily damaged and often bend or deform at the ends, the ends of the heat-conducting pins can be pinched tightly and then pulled downwards to separate the heat-conducting pins from the mounting plate. At this time, the bent or deformed heat-conducting pins can be removed and replaced to avoid the bent or deformed heat-conducting pins affecting subsequent insertion and removal.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-7 As shown, this utility model provides a technical solution: a heat-conducting composite phase change element that is resistant to insertion and removal, including a heat-conducting plate 1, heat-conducting pillars 2, heat-conducting pins 3, locking holes 4, and a heat-conducting interface material 5. The top of the heat-conducting plate 1 is provided with heat-conducting pillars 2 for heat dissipation, and the heat-conducting pillars 2 are evenly distributed at the top of the heat-conducting plate 1. The end of the heat-conducting plate 1 away from the heat-conducting pillars 2 is provided with heat-conducting pins 3 for insertion and positioning, and the heat-conducting pins 3 are symmetrically distributed at the bottom of the heat-conducting plate 1. Locking holes 4 for connection are opened at both ends of the heat-conducting plate 1. The side of the bottom of the heat-conducting plate 1 near the heat-conducting pins 3 is provided with a heat-conducting interface material 5. Fixing pillars 6 are provided on both sides of the heat-conducting plate 1, and the fixing pillars 6 are symmetrically distributed on both sides of the heat-conducting plate 1. A handle 7 is sleeved on the surface of the fixing pillar 6.

[0019] like Figure 5 As shown, handles 7 are symmetrically distributed on both sides of heat-conducting plate 1, and the shape of handles 7 matches that of heat-conducting plate 1. A U-shaped seat 8 is provided at one end of heat-conducting plate 1 near the fixed column 6. An adjustment plate 9 is provided inside the U-shaped seat 8. A displacement slider 10 that is slidably connected to the U-shaped seat 8 is provided at the bottom end of the adjustment plate 9. Thermal interface material 5 is a dielectric material used to fill the micro-gaps between the contact surface of electronic devices and heat sinks, improving heat dissipation efficiency by eliminating air and reducing contact thermal resistance. The displacement sliders 10 are symmetrically distributed at the bottom of the adjustment plate 9, and the U-shaped seat 8 has a groove inside that matches the displacement sliders 10, so that the adjustment plate 9 can be relatively stable when it moves.

[0020] like Figure 5 As shown, a first limiting spring 11 connected to the U-shaped seat 8 is provided on one side of the adjusting plate 9, and the first limiting spring 11 is symmetrically distributed on one side of the adjusting plate 9. A trapezoidal tooth 12 for limiting the movement of the handle 7 is provided on the side of the adjusting plate 9 away from the first limiting spring 11.

[0021] There is no interference between the height of the heat-conducting column 2 and the handle 7. The hollow groove inside the handle 7 can accommodate the heat-conducting column 2 without touching it during rotation, making the rotation operation smoother.

[0022] When insertion or removal is required, the handle 7 can be pulled upwards, allowing it to rotate along the fixed post 6. During rotation, the handle 7 presses against the trapezoidal teeth 12 on one side of the adjusting plate 9, moving the connected adjusting plate 9. This allows the adjusting plate 9 to slide within the U-shaped seat 8 via the displacement slider 10 at its bottom. As the adjusting plate 9 moves, it presses against the first limiting spring 11 on one side, causing it to contract. Simultaneously, as the handle 7 is pulled further, it can be removed from the U-shaped seat 8. Similarly, the handle 7 on the other side of the heat-conducting plate 1 can be rotated and removed simultaneously. Both handles 7 can then be placed vertically. Finally, both handles 7 can be pulled upwards simultaneously, allowing the heat-conducting plate 1 to move upwards evenly, with a relatively narrow edge. This avoids wobbling and deviation when directly pinching and pulling the edge of the heat-conducting plate 1 upwards. The vertically set handle 7 makes it easier and more stable to pull. Conversely, after insertion, the two handles 7 can be rotated in opposite directions to re-lock into the U-shaped seat 8. At this time, the first limit spring 11 resets, which moves the connected adjustment plate 9. This allows the trapezoidal teeth 12 at one end of the adjustment plate 9 to limit the handle 7, achieving a stable anti-wobbling effect when placed. Therefore, it has a good insertion and removal resistance when using the heat-conducting composite phase change element. Phase change material is a type of substance that absorbs or releases latent heat through physical state changes. The connection of the handle 7 allows the phase change element made of phase change material to achieve stable insertion and removal with the structure to be connected, avoiding deviations during insertion and removal that could lead to deformation and damage.

[0023] like Figure 7As shown, the heat-conducting pin 3 is provided with an installation plate 13 connected to the bottom of the heat-conducting plate 1. The installation plate 13 has a cavity 14 inside. The cavity 14 is provided with a limiting block 15 connected to the heat-conducting pin 3. The limiting block 15 is shaped like a "T". Guide rods 16 connected to the cavity 14 pass through both ends of the limiting block 15.

[0024] The limiting blocks 15 are symmetrically distributed inside the mounting plate 13, which allows them to be clamped to both ends of the heat-conducting pins 3 after they are extended, thus achieving stability after installation. Furthermore, the ends of the mounting plate 13 are tightly fitted to the inside of the cavity 14, so that the heat-conducting pins 3 not only have a positioning and fixing effect during use, but also assist in heat conduction and improve the efficiency of heat conduction.

[0025] like Figure 7 As shown, a second limiting spring 17 is connected between one side of the limiting block 15 and the cavity 14, and a locking groove 18 matching the limiting block 15 is opened inside the heat-conducting pin 3.

[0026] The end of the limiting block 15 is spherical, which allows it to move when squeezed, thus avoiding interference with the locking groove 18.

[0027] Since the heat-conducting pin 3 is a vulnerable part and often bends or deforms at its end, the end of the heat-conducting pin 3 can be pinched tightly and then pulled downwards. When the heat-conducting pin 3 is pulled downwards, the internal locking groove 18 moves, which in turn pushes the internal limiting block 15, allowing the limiting block 15 to move on the surface of the guide rod 16 and be housed inside the cavity 14. At the same time, during the movement, the second limiting spring 17 is squeezed, causing the second limiting spring 17 to contract. Then, by pulling the heat-conducting pin 3, the heat-conducting pin 3 can be separated from the mounting plate 13. At this time, the bent or deformed heat-conducting pin 3 can be removed and replaced to avoid the bent or deformed heat-conducting pin 3 affecting subsequent insertion and removal. It should be noted that this device can not only be used for heat conduction after being connected to the optical transceiver module, but also the composite phase change element formed by this thermally conductive phase change material can be used inside other structures that require heat conduction. This gives it not only good heat conduction effect, but also good applicability. Furthermore, the thermally conductive phase change material is composed of an insertion-resistant layer and a phase change thermally conductive layer.

[0028] Working principle: First, the heat-conducting pins 3 are inserted and installed at the required positions, ensuring that the heat-conducting interface material 5 coincides with the required position. Then, the screws are tightened after passing through the locking holes 4, achieving stability of the heat-conducting composite phase change element during installation. At the same time, through the heat-conducting plate 1, heat-conducting pins 3, and heat-conducting interface material 5, heat can be quickly dispersed into the heat-conducting pillars 2, thereby distributing the heat and achieving rapid heat dissipation. When it is necessary to insert or remove it, the handle 7 can be rotated to release the restriction of the trapezoidal teeth 12 and placed vertically, making it easy to pull the heat-conducting composite phase change element vertically. Compared with manual insertion and removal, the insertion and removal process is more stable and less prone to bending and deformation, making it convenient to insert and remove the heat-conducting composite phase change element.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
