Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, and in particular to a metal composite heat sink structure that is easy to assemble and disassemble. Background Technology

[0002] A heat sink is a device used for heat dissipation, usually made of metal. It is widely used in electronic equipment, mechanical equipment, and industrial equipment to quickly conduct and dissipate the heat generated during equipment operation into the surrounding environment. It can significantly improve the heat dissipation efficiency of the equipment, thereby preventing overheating, extending its service life, and ensuring its stable operation.

[0003] In most existing systems, heat sinks are directly connected and fixed to equipment using bolts or welding. When it is necessary to disassemble the heat sink, the bolts need to be loosened or the heat sink needs to be cut directly. The disassembly process is relatively complicated and inconvenient for repairing or replacing the heat sink.

[0004] Therefore, to address the issue that the disassembly process is complex and inconvenient for repairing or replacing heat sinks when they are installed and fixed by bolts or welding, a limiting structure can be set to limit the heat sink, allowing for quick disassembly and placement of the heat sink. Furthermore, a clamping structure can be set to clamp and fix the limited heat sink. Utility Model Content

[0005] To overcome the problem that in the process of using heat sinks, most of them are directly connected and fixed to the equipment by bolts or welding. When it is necessary to disassemble the heat sink, it is necessary to loosen the bolts or cut the heat sink directly. The disassembly process is complicated and it is not convenient to repair or replace the heat sink.

[0006] The technical solution of this utility model is as follows: a metal composite heat sink structure that is easy to assemble and disassemble, including a heat sink base, a heat sink groove is provided on the bottom surface of the heat sink base, a limiting seat is provided on one side of the heat sink base, the limiting seat is fixedly connected to the inner wall of the heat sink base, a limiting slot is provided on the side of the limiting seat, a clamping seat is provided on the other side of the heat sink base, the clamping seat is slidably connected to the inner wall of the heat sink base, and a clamping groove is provided on the top surface of the clamping seat.

[0007] Preferably, the heat dissipation grooves are evenly distributed on the bottom surface of the heat dissipation base, the limiting slots are evenly distributed on the limiting slots, the heat dissipation grooves and the limiting slots are interconnected, and the clamping slots are evenly distributed on the clamping base, the heat dissipation grooves and the clamping slots are interconnected.

[0008] Preferably, mounting blocks are symmetrically welded and fixed to the bottom side of the heat dissipation base, the mounting blocks are symmetrically distributed on the heat dissipation base, and mounting holes are opened on the top surface of the mounting blocks.

[0009] Preferably, the inner wall of the limiting slot is slidably connected to a heat sink body, and the side of the heat sink body is provided with serrated grooves at equal intervals, and the serrated grooves are symmetrically distributed on the heat sink body.

[0010] Preferably, a limiting slot is provided on the side of the heat sink body near the clamping seat. The limiting slot has a trapezoidal structure, and the bottom surface of the heat sink body is provided with an arc-shaped chamfer, which is located directly below the limiting slot.

[0011] Preferably, a clamping screw is rotatably connected to the side of the clamping seat, the clamping screw is rotatably connected to the heat dissipation base via a thread, a knob is fixedly connected to the end of the clamping screw, and a limiting slide rod is fixedly connected to the side of the clamping seat. The limiting slide rod is symmetrically distributed on the clamping seat and is slidably connected to the heat dissipation base.

[0012] Preferably, the inner wall of the clamping groove is symmetrically provided with limiting grooves, and the inner wall of the limiting groove is slidably connected with a limiting pin. One end of the limiting pin is a trapezoidal structure, and the other end of the limiting pin is fixedly connected with a limiting spring. The end of the limiting spring is fixedly connected to the inner wall of the clamping groove.

[0013] The beneficial effects of this utility model are:

[0014] When it is necessary to disassemble and replace the heat sink, turn the knob to loosen the clamping seat by turning the clamping screw. Under the action of the limit spring, the limit pin is still engaged with the limit slot, limiting the heat sink body. Select the heat sink to be replaced and pull it upward. This will compress the limit pin. Due to the inclined structure of the limit pin and the limit slot, the thrust generated by the upward movement of the heat sink will push the limit pin to slide in the limit groove, compressing the limit spring and thus releasing the restriction of the heat sink, making it easy to remove the heat sink for replacement.

[0015] 2. After disassembly, align the new heat sink with the limiting slot and clamping slot and insert it downwards. Push the limiting pin by the arc-shaped chamfer at the bottom to move it, so that the heat sink can be reinserted into the limiting slot and clamping slot. Under the action of the limiting spring, the limiting pin will be pushed into the limiting slot to engage, thus re-limiting the heat sink and completing the disassembly and replacement of the heat sink.

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a metal composite heat sink structure that is easy to assemble and disassemble, including a heat sink base 1, a heat sink groove 2 on the bottom surface of the heat sink base 1, a limiting seat 3 on one side of the heat sink base 1, the limiting seat 3 being fixedly connected to the inner wall of the heat sink base 1, a limiting groove 4 on the side of the limiting seat 3, a clamping seat 5 on the other side of the heat sink base 1, the clamping seat 5 being slidably connected to the inner wall of the heat sink base 1, and a clamping groove 6 on the top surface of the clamping seat 5.

[0024] Heat dissipation slots 2 are evenly distributed on the bottom surface of heat dissipation base 1, and limiting slots 4 are evenly distributed on limiting base 3. Heat dissipation slots 2 and limiting slots 4 are connected. Clamping slots 6 are evenly distributed on clamping base 5. Heat dissipation slots 2 and clamping slots 6 are connected. Heat dissipation slots 2 facilitate air circulation, allowing the heat generated by the equipment to quickly enter the heat dissipation base 1 for heat dissipation. The limiting slots 4 on the limiting base 3 can limit the placement of the heat dissipation fins, thereby positioning the heat dissipation fins. The clamping slots 6 on the clamping base 5 facilitate clamping and fixing the heat dissipation fins.

[0025] Mounting blocks 101 are symmetrically welded and fixed to the bottom side of the heat dissipation base 1. The mounting blocks 101 are symmetrically distributed on the heat dissipation base 1. Mounting holes 102 are opened on the top surface of the mounting blocks 101. The mounting holes 102 opened on the mounting blocks 101 facilitate the installation and fixing of the entire device with the equipment that needs heat dissipation, ensuring the stability of the device during use.

[0026] The inner wall of the limiting slot 4 is slidably connected to the heat sink body 301. The side of the heat sink body 301 is provided with serrated grooves 302 at equal intervals. The serrated grooves 302 are symmetrically distributed on the heat sink body 301. The serrated grooves 302 on both sides of the heat sink body 301 can increase the heat dissipation area and air circulation efficiency of the heat sink, ensure smooth air flow, and thus improve the overall heat dissipation effect of the heat sink.

[0027] A limiting slot 303 is provided on the side of the heat sink body 301 near the clamping seat 5. The limiting slot 303 has a trapezoidal structure. The bottom surface of the heat sink body 301 is provided with an arc-shaped chamfer 304. The arc-shaped chamfer 304 is located directly below the limiting slot 303. The limiting slot 303 can be used to connect and restrict the heat sink, preventing the heat sink from slipping out between the limiting slot 4 and the clamping slot 6. The arc-shaped chamfer 304 at the bottom of the heat sink facilitates the connection and installation of the heat sink.

[0028] A clamping screw 501 is rotatably connected to the side of the clamping seat 5. The clamping screw 501 is rotatably connected to the heat dissipation base 1 via a thread. A knob 502 is fixedly connected to the end of the clamping screw 501. A limiting slide rod 503 is fixedly connected to the side of the clamping seat 5. The limiting slide rod 503 is symmetrically distributed on the clamping seat 5. The limiting slide rod 503 is slidably connected to the heat dissipation base 1. By rotating the knob 502, the clamping screw 501 is driven to rotate. During the movement of the clamping seat 5, the limiting slide rod 503 is driven to slide within the heat dissipation base 1, making the movement of the clamping seat 5 more stable. This allows the heat dissipation fins placed in the limiting card holder 3 to be clamped and fixed.

[0029] The inner wall of the clamping groove 6 is symmetrically provided with limiting grooves 504. The inner wall of the limiting groove 504 is slidably connected to a limiting pin 505. One end of the limiting pin 505 is a trapezoidal structure, and the other end of the limiting pin 505 is fixedly connected to a limiting spring 506. The end of the limiting spring 506 is fixedly connected to the inner wall of the clamping groove 6. The elastic force of the limiting spring 506 pushes the limiting pin 505 to slide in the limiting groove 504, so that the limiting pin 505 is inserted into the limiting slot 303, thereby connecting and restricting the heat sink.

[0030] Working principle: According to Figures 1-3 and Figure 5 As shown, during operation, multiple heat sink bodies 301 are sequentially inserted into the limiting slots 4 for positioning. The clamping screw 501 is rotated by turning the knob 502, thereby pushing the clamping seat 5 to slide stably within the heat sink base 1. This allows the limiting pin 505 to be inserted into the limiting slot 303. As the clamping screw 501 is continuously rotated to clamp and fix the heat sink, the limiting pin 505 will slide within the limiting groove 504, compressing the limiting spring 506. The elastic force of the limiting spring 506 helps the clamping seat 5 to clamp the heat sink more stably, ensuring that it will not loosen due to vibration or external force after fixing.

[0031] according to Figures 1-4 As shown, the mounting holes 102 on the mounting block 101 facilitate the installation and fixation of the heat sink base 1 with the heat sink to the equipment that needs heat dissipation, ensuring the stability of the heat sink base 1 during use. The heat dissipation grooves 2 facilitate air circulation, allowing the heat generated by the equipment to quickly enter the heat sink base 1 for heat dissipation. The serrated grooves 302 on both sides of the heat sink body 301 increase the heat dissipation area and air circulation efficiency of the heat sink, ensuring smooth airflow and thus improving the overall heat dissipation effect of the heat sink.

[0032] according to Figures 1-5As shown, when the heat sink needs to be disassembled and replaced, the clamping screw 501 is rotated by knob 502 to loosen the clamping seat 5, so that the limiting pin 505 is still engaged with the limiting slot 303 under the action of the limiting spring 506, limiting the heat sink body 301. Select the set of heat sinks to be replaced and pull it upward, so that the limiting pin 505 is squeezed. Due to the inclined structure of the limiting pin 505 and the limiting slot 303, the thrust generated by the upward movement of the heat sink will push the limiting pin 505 to slide in the limiting groove 504. The limiting spring 506 is compressed, thereby releasing the restriction of the heat sink and making it easy to remove and replace the heat sink. The new heat sink is aligned with the limiting slot 4 and the clamping slot 6 and inserted downwards. The bottom arc chamfer 304 pushes the limiting pin 505 to move, making it easy for the heat sink to be reinserted into the limiting slot 4 and the clamping slot 6. Under the action of the limiting spring 506, the limiting pin 505 is pushed into the limiting slot 303 to engage, thus re-limiting the heat sink and completing the removal and replacement of the heat sink.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] 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.
