Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature equalization plate installation technology, specifically a temperature equalization plate locking structure. Background Technology
[0002] As a highly efficient two-phase flow heat transfer element, the vapor chamber plays a crucial role in the thermal management system of modern electronic devices. Internally, through a vacuum chamber and capillary structure, it utilizes the phase change circulation of the working fluid to achieve extremely rapid heat diffusion, quickly and evenly distributing the high heat from localized hotspots across the entire surface, thus significantly improving heat dissipation efficiency. However, the excellent heat dissipation performance of a vapor chamber largely depends on a stable, tight, and low-thermal-resistance contact between it and the heat-generating components, which places stringent requirements on its locking structure. Existing locking methods generally have some inherent drawbacks. For example, the method of directly locking with multiple screws is not only cumbersome to install, requiring each screw to be tightened individually, which is extremely inconvenient on space-constrained circuit boards and reduces production efficiency, but also difficult to control the torque of the screws. Overtightening may damage the vapor chamber or the chip, while loosening may affect the heat dissipation effect due to poor contact or vibration. Therefore, we propose a vapor chamber locking structure. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a heat spreader locking structure that enables the rapid installation and disassembly of the heat spreader while ensuring a stable and reliable locking process with uniform force. This effectively avoids damage to the heat spreader or chip caused by uneven locking force or improper operation, and improves the ease of assembly in confined spaces. As a result, it significantly improves heat dissipation efficiency and assembly and maintenance efficiency, and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a temperature distribution plate locking structure, including a mounting frame and a moving component; Mounting frame: An internally sliding heat exchange plate is connected, with the front end of the heat exchange plate located outside the mounting frame. A protective shell is fixed to the upper rear side of the mounting frame. Two corresponding fastening components are installed on the upper left and right sides of the mounting frame, and two corresponding support components are installed on the rear side of the mounting frame. The moving component includes a gear, rack, L-shaped moving frame, fixing block, and first spring. A gear is rotatably connected to the upper rear end of the mounting frame. Two parallel racks are arranged on the upper and lower sides of the gear, both meshing with the gear. An L-shaped moving frame is fixed to the side of the racks. A guide opening is provided on the rear side of the L-shaped moving frame, and a fixing block is disposed inside the guide opening. Two fixing blocks are fixed to the rear side of the mounting frame. A first spring is fixed to the side of each fixing block, with the end of the first spring furthest from the fixing block fixed inside the corresponding guide opening. The gear, rack, L-shaped moving frame, fixing block, and first spring are all located inside the protective shell. The two L-shaped moving frames are respectively connected to two fastening components. By setting the moving components, the user can pull one fastening block to move the other fastening block synchronously, allowing for quick disassembly of the heat exchange plate.
[0005] Furthermore, the fastening assembly includes a fastening block, a limiting strip, a sliding groove, a trapezoidal block, and a second spring. Two corresponding sliding openings are provided on the upper ends of the left and right sides of the mounting frame. A fastening block is slidably connected inside the sliding opening. Two corresponding limiting strips are fixed to the front and rear sides of the fastening block. Two corresponding sliding grooves are provided on the front and rear sides inside the mounting frame. The limiting strips are slidably connected inside the corresponding sliding grooves. The fastening block is fixed to the side of its corresponding L-shaped movable frame. A groove is provided on the lower side of the fastening block. A trapezoidal block is slidably connected inside the groove. A second spring is fixed to the upper side of the trapezoidal block, and the second spring is fixed inside the groove. The lower sides of both the fastening block and the trapezoidal block are in contact with the upper side of the heat exchange plate. By setting the fastening assembly in conjunction with the support assembly and the clamping assembly, the heat exchange plate is locked.
[0006] Furthermore, the support assembly includes a slide rod, a support plate, a pull bar, and a third spring. Two corresponding pull bars are provided on the rear side of the mounting frame, and two corresponding slide rods are fixed to the front side of the pull bars. Four corresponding sliding holes are opened at the upper and lower ends of the rear side of the mounting frame. The slide rods are slidably connected inside the corresponding sliding holes. A support plate is fixed to the end face of the slide rod inside the mounting frame. All four support plates are in contact with the rear side of the heat exchange plate. A third spring is sleeved on the circumferential surface of the slide rod. The rear end of the third spring is fixed to the front side of its corresponding pull bar, and the front end of the third spring is fixed to the rear side of the mounting frame. By setting up the support assembly, the heat exchange plate is initially pressed down.
[0007] Furthermore, it also includes a clamping assembly, which includes a clamping strip and a pad. The rear side of the mounting frame has two corresponding strip openings, and the clamping strip is slidably connected inside the strip opening. The clamping strip is fixed to the front side of the corresponding pull strip, and a pad is fixed to the front side of the clamping strip. Both pads are in contact with the rear side of the heat exchange plate. By setting the clamping assembly, the heat exchange plate is further clamped.
[0008] Furthermore, four corresponding mounting blocks are fixed on the left and right sides of the mounting frame, and mounting holes are provided in the middle of the mounting blocks. The mounting frame is fixed on the circuit board on which the heat exchange plate needs to be installed by setting the mounting blocks and mounting holes.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This temperature distribution plate locking structure has the following advantages: 1. Through the ingenious linkage between the moving and fastening components, rapid and synchronous locking of the heat spreader is achieved. When the operator pulls one side of the fastening block in one direction, the other side of the fastening block moves in the opposite direction through gear and rack transmission, causing the locking mechanisms on both sides to operate simultaneously. This design not only simplifies the operation steps and improves assembly efficiency, but also ensures that the heat spreader is subjected to uniform force, avoiding the problem of unstable heat dissipation interface caused by weak locking on one side, thereby ensuring the reliability of heat conduction.
[0010] 2. The elastic synergy between the support and clamping components provides multi-dimensional and adaptive clamping force to the heat exchange plate. The support plate and pad apply continuous pressure from the rear, forming a stable clamp with the upper fastening block, so that the heat exchange plate is firmly locked. The trapezoidal block can compensate for the tolerance under the action of the second spring, ensuring that the heat exchange plate will not loosen during use. Attached Figure Description

The lower sides of both the fastening block 51 and the trapezoidal block 54 are in contact with the upper side of the heat exchange plate 2. The support assembly 6 includes a sliding rod 61, a support plate 62, a pull bar 63, and... The third spring 64 is mounted on the rear side of the mounting frame 1.

Four corresponding sliding holes are provided at the upper and lower ends of the rear side of the mounting frame 1. The sliding rods 61 are slidably connected inside the corresponding sliding holes. A support plate 62 is fixed to the end face of the sliding rod 61 inside the mounting frame 1. All four support plates 62 are in contact with the rear side of the heat exchange plate 2. A third spring 64 is sleeved on the circumference of the sliding rod 61. The rear end of the third spring 64 is fixed to the front side of its corresponding pull bar 63, and the front end of the third spring 64 is fixed to the mounting frame 1. The rear side of the frame 1 also includes a clamping assembly 7, which includes a clamping strip 71 and a pad 72. Two corresponding strip openings are provided on the rear side of the frame 1. The clamping strip 71 is slidably connected inside the strip openings. The clamping strip 71 is fixed to the front side of the corresponding pull strip 63. The pad 72 is fixed to the front side of the clamping strip 71. Both pads 72 are in contact with the rear side of the heat exchange plate 2. The heat exchange plate 2 is further clamped by setting the clamping assembly 7. The heat exchange plate 2 is initially clamped by setting the support assembly 6. The heat exchange plate 2 is locked by setting the fastening assembly 5 in conjunction with the support assembly 6 and the clamping assembly 7. Moving component 4 includes a gear 41, a rack 42, an L-shaped moving frame 43, a fixing block 44, and a first spring 45. The gear 41 is rotatably connected to the upper rear end of the mounting frame 1. Two parallel racks 42 are arranged on the upper and lower sides of the gear 41, and both racks 42 mesh with the gear 41. An L-shaped moving frame 43 is fixed to the side of the racks 42. A guide opening is provided on the rear side of the L-shaped moving frame 43, and a fixing block 44 is arranged inside the guide opening. Both fixing blocks 44 are fixed to the rear side of the mounting frame 1. A first spring 45 is fixed to the side of the fixed block 44. The end of the first spring 45 away from the fixed block 44 is fixed inside the corresponding guide opening. The gear 41, rack 42, L-shaped moving frame 43, fixed block 44 and the first spring 45 are all located inside the protective shell 3. The two L-shaped moving frames 43 are respectively connected to two fastening components 5. By setting the moving components 4, the user can pull the fastening block 51 on one side to drive the fastening block 51 on the other side to move synchronously. In this case, the heat exchange plate 2 can be quickly disassembled.
[0015] The mounting frame 1 has four corresponding mounting blocks 8 fixed on its left and right sides. The mounting blocks 8 have mounting holes 9 in the middle. The mounting frame 1 is fixed on the circuit board on which the heat exchange plate 2 needs to be installed by setting the mounting blocks 8 and mounting holes 9.
[0016] The working principle of the temperature distribution plate locking structure provided by this utility model is as follows: First, use bolts to fix the mounting frame 1 to the circuit board or base where the temperature distribution plate 2 needs to be installed. Next, the heat spreader 2 is installed: the user pulls outward on the fastening block 51 of the fastening component 5 on one side. This action will drive the L-shaped moving frame 43 fixed thereto to move. The L-shaped moving frame 43 then drives the rack 42 connected to it to move horizontally. Since the gear 41 meshes with the upper and lower racks 42 at the same time, the movement of one rack 42 will force the gear 41 to rotate, thereby driving the rack 42 on the other side to move synchronously in the opposite direction. Finally, the two fastening blocks 51 overcome the elastic force of the first spring 45 and move away from each other, making room for the insertion of the heat spreader 2. At this time, the heat spreader 2 is slid into place along the inside of the mounting frame 1. During its insertion, the rear side of the heat spreader 2 will first contact and compress the support plate 62 of the support component 6 and the pad 72 of the pressing component 7, which are continuously pressured by the third spring 64. These two components work together to form a stable pre-support and initial compression of the heat spreader 2 from the rear. Once the heat exchange plate 2 is in place, the user releases the previously pulled fastening block 51. At this time, under the restoring force of the first spring 45, the two racks 42 are linked by the gear 41, driving the L-shaped moving frame 43 on both sides and the fastening block 51 to move synchronously back to the center. Under the action of the second spring 55 in its groove, the trapezoidal block 54 on the lower side of the fastening block 51 can adaptively press against the upper surface of the heat exchange plate 2. At the same time, the limiting strip 52 slides in the slide groove 53 to ensure smooth movement, thus completing the final locking of the heat exchange plate 2 from above.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
