Different radiator structures can achieve different degrees of heat dissipation. The heat dissipation structure of cold forging process can be improved in many aspects to improve its heat dissipation performance, manufacturing efficiency and reliability.

[0003] A search revealed Chinese Patent Publication No. CN202660505U, which discloses an insert-type heat dissipation fin structure. Traditional lamp heat sink structures are generally extruded or sand-cast, and some use fins inserted into a base. These structures are generally heavy, use a large amount of aluminum alloy, and have low heat dissipation efficiency. This invention features multiple slots on a fixed base plate, into which heat dissipation fins are inserted. Multiple tension bosses are provided on one or both sides of the heat dissipation fins, with gaps between the tension bosses and the fins. The slots are located on the surface or side edge of the fixed base plate. Under the same conditions, this invention increases the effective heat dissipation area of ​​the heat sink, reduces manufacturing costs, effectively enhances airflow, and maximizes the use of natural wind to improve heat dissipation. As an outdoor lamp, it effectively reduces wind resistance and improves heat dissipation.

[0004] The aforementioned utility models mostly employ fanless aluminum extrusion heat dissipation fins for natural heat dissipation. However, the fanless heat dissipation fins natural heat dissipation structure sometimes fails to meet the heat dissipation requirements of high-performance CPUs. Therefore, a heat dissipation structure using a cold forging process is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat dissipation structure using a cold forging process, which aims to improve the existing technology's inability to meet the heat dissipation requirements of high-performance CPUs and facilitate the disassembly of heat sinks.

[0010] Furthermore, the clamping assembly includes a connecting plate, a connecting rod is fixedly connected to the upper part of the connecting plate, a clamping plate is fixedly connected to the upper part of the connecting rod, and two slots distributed on the left and right are opened at the lower part of the heat sink.

[0011] By adopting the above technical solution, the clamp is fixed inside the slot to secure the heat sink.

[0012] Furthermore, the other end of the connecting plate is fixedly connected to the rack, and the rack is meshed with the outer periphery of the gear.

[0014] Furthermore, the connecting plate is slidably connected inside the heat sink, and the two clamping plates are slidably connected on the left and right sides of the middle part of the heat sink.

[0015] By adopting the above technical solution, the connecting plate drives the clamping plate to move together.

[0016] Furthermore, the height of the clamping plate matches the height of the slot, and the connecting rod is slidably connected inside the heat sink.

[0018] Furthermore, the gear is rotatably connected to the middle of the heat sink, and the two ends of the torsion spring are fixedly connected inside the heat sink.

[0020] Furthermore, the heat sink has evenly distributed mounting holes at its edge.

[0021] By adopting the above technical solution, the mounting holes can easily fix the heat sink inside the chassis.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by combining the heat sink, the cylindrical heat sink unit and the heat sink block, compared with the aluminum extrusion heat sink, the overall weight is reduced and the heat dissipation area is maximized while ensuring reliable product quality, thereby improving the heat dissipation performance.

[0024] 2. In this utility model, through the cooperation of the drive component and the clamping component, rotating the knob causes the gear to rotate, which in turn causes the clamping plate to loosen the heat sink block.

Replacing the aging heat sink block improves the heat dissipation performance and extends the equipment life. Attached Figure Description

[0031] 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.

[0032] Reference Figure 1-3 An embodiment of this utility model provides a heat dissipation structure for a cold forging process, including a heat dissipation plate 1, a plurality of uniformly distributed cylindrical heat dissipation units 2 fixedly connected to the upper part of the heat dissipation plate 1, a driving component 41 provided in the middle of the heat dissipation plate 1, a clamping component 42 provided in the middle of the heat dissipation plate 1, and a heat dissipation block 3 slidably connected in the middle of the heat dissipation plate 1.

[0033] Specifically, the modern integrated cylindrical cold-forged heatsink consists of a heatsink plate 1 and cylindrical heatsink units 2. The heatsink plate 1 supports the cylindrical heatsink units 2, which have a diameter of 4mm and a spacing of 10mm. The cylindrical heatsink units 2 maximize the heat dissipation area, thereby improving heat dissipation performance. The combination of the heatsink plate 1, cylindrical heatsink units 2, and heatsink blocks 3 reduces the overall weight of the device while ensuring reliable product quality. This combination of the modern integrated cylindrical cold-forged heatsink and heatsink blocks 3, based on the principle of heat circulation in copper pipes, distributes CPU heat through two heat dissipation paths, solving the problem of limited space but high heat dissipation requirements. The modern integrated cylindrical cold-forged heatsink is produced by placing 1070 pure aluminum billets in a precision cold-forging mold and extruding them through a press to achieve plastic deformation. It has no interface impedance, meaning that signals can propagate freely in the circuit without being affected by signal reflection or loss caused by impedance mismatch. The 1070 aluminum used is a lightweight metal, which makes the heat sink relatively light and also has good thermal conductivity, which can quickly conduct heat to the surface of the heat sink and effectively dissipate it to the surrounding environment. The heat sink 3 is an important component for managing and controlling heat transfer.

[0034] Reference Figure 2-4 The drive assembly 41 includes a gear 411, a torsion spring 412 fixedly connected to the upper part of the gear 411, a knob 414 fixedly connected to the bottom of the gear 411, two racks 413 slidably connected inside the heat sink 1, the clamping assembly 42 includes a connecting plate 421, a connecting rod 422 fixedly connected to the upper part of the connecting plate 421, a clamping plate 423 fixedly connected to the upper part of the connecting rod 422, two slots 424 slidably connected to the lower part of the heat sink 3, the other end of the connecting plate 421 is fixedly connected to the rack 413, the rack 413 is meshed with the outer periphery of the gear 411, and the connecting plate 421 is slidably connected inside the heat sink 1.

[0035] Specifically, the drive assembly 41 and the clamping assembly 42 constitute the disassembly mechanism 4. The gear 411 drives the rack 413 to move, and after rotation, the gear 411 returns to its original position via the elastic force of the torsion spring 412. The rack 413 drives the connecting plate 421 to move, the connecting plate 421 drives the connecting rod 422 and the clamping plate 423 to move, the connecting rod 422 connects the connecting plate 421 and the clamping plate 423, the clamping plate 423 clamps the heat sink 3 for easy disassembly, and the slot 424 allows the clamping plate 423 to hold the heat sink 3 in place for fixation.

[0036] Reference Figure 1 , Figure 3 and Figure 4Two clamping plates 423 are slidably connected to the left and right sides of the middle part of the heat sink 1. The height of the clamping plates 423 matches the height of the slots 424. The connecting rod 422 is slidably connected inside the heat sink 1. The gear 411 is rotatably connected to the middle part of the heat sink 1. The two ends of the torsion spring 412 are fixedly connected to the inside of the heat sink 1. The edge of the heat sink 1 is provided with evenly distributed mounting holes 5.

[0037] Specifically, the length of the clamping plate 423 is the same as the length of the heat sink 3, and the housing can stably clamp the heat sink 3. The torsion spring 412 is made of stainless steel, which has good elasticity and toughness and can quickly return to its original shape after being subjected to force. The mounting hole 5 makes it convenient to install the heat sink 1 on the component that needs to be cooled.

[0038] Working principle: When installing the heat sink 3, first rotate the knob 414 to make the gear 411 drive the rack 413 to move, causing the connecting plate 421 to move outward, and the connecting rod 422 to move the clamping plate 423 to both sides until the heat sink 3 can be put into the heat sink 1. Place the heat sink 3 into the middle of the heat sink 1, and align the slot 424 with the clamping plate 423. The elasticity of the torsion spring 412 will cause the gear 411 to rotate, driving the rack 413 to move, causing the connecting plate 421 to move towards the center. The movement of the connecting plate 421 will drive the connecting rod 422 to move, causing the clamping plate 423 to move towards the center to clamp the heat sink 3. The clamping plate 423 is stuck in the slot 424 to fix and support the heat sink 3, preventing the heat sink 3 from falling and being damaged due to the movement of the heat sink 1. Install the heat sink 1 on the component that needs to be cooled through the mounting hole 5.
