Description

Technical Field

[0001] The utility model relates to the technical field of radiating fins, in particular to a combined copper-embedded radiating fin. Background Art

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It's typically made of aluminum alloy, brass, or bronze in the form of plates, sheets, or multiple sheets. For example, the CPU in a computer requires a fairly large heat sink, as do the power and line transistors in a television, and the power amplifier tubes in an amplifier. Heat sinks are typically coated with a layer of thermal grease on the contact surface between the electronic component and the heat sink. This allows the heat generated by the component to be more efficiently transferred to the heat sink, where it is then dissipated into the surrounding air.

[0003] In Chinese patent CN201720219202.4, the utility model discloses a combined heat sink, comprising a combined heat sink body, a heat sink base disposed at the bottom of the combined heat sink body, a plurality of heat sink fin bodies mounted on the heat sink base, the heat sink body comprising a heat sink fin substrate, an arc-shaped guide plate, heat dissipation holes, and a thermal grease layer, the heat sink substrate having the arc-shaped guide plate disposed on one surface and the thermal grease layer disposed on the other surface. The utility model, through the provision of a combined mounting structure, can securely combine two heat sinks, making assembly and disassembly simple and convenient, and providing a secure installation. The distance between the heat sinks is limited by a convex structure and a slot, ensuring air circulation between the heat sinks. The provision of a first arc-shaped guide plate, a second arc-shaped guide plate, and heat dissipation holes accelerates the air circulation between the heat sinks, improving the heat dissipation effect of the combined heat sink, and making it easy to use.

[0004] Some existing modular heat sinks have complex structural designs, which can be time-consuming and labor-intensive to assemble and disassemble. For example, some heat sinks have inadequately designed connecting components, requiring significant force or specialized tools for installation, and potentially damaging components during disassembly. This creates inconvenience for users during installation, maintenance, and replacement.

[0005] Therefore, in order to solve the above problems, a combined copper-embedded heat sink is proposed. Utility Model Content

The utility model reduces the contact thermal resistance between different components by providing an embedded copper heat sink assembly and an integrated arrangement of copper sheets, vertical heat pipes and horizontal heat pipes.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1 As shown, this embodiment includes an embedded copper heat sink assembly 1, a fixing assembly 2, and a combined frame assembly 3.

[0026] See also Figures 1 to 4 As shown, a fixing assembly 2 is installed at the bottom of the embedded copper heat sink assembly 1 , and a combined frame assembly 3 is installed on the side of the fixing assembly 2 .

[0027] The copper-embedded heat sink assembly 1 includes a heat sink body 101, to which a copper sheet 102 is fixedly connected on the side, and a vertical heat pipe 103 is fixedly connected to the outer wall of the copper sheet 102, and a horizontal heat pipe 104 is fixedly connected to the side of the vertical heat pipe 103. The copper sheet 102, the vertical heat pipe 103, and the horizontal heat pipe 104 are integrated to reduce the contact thermal resistance between different components. Because in traditional heat sinks, there may be tiny gaps or poor contact points between the connections between components, this integrated structure ensures that heat can be quickly and smoothly transferred from the copper sheet 102 to the heat pipe, and the vertical heat pipe 103 and the horizontal heat pipe 104 form a connecting structure, and the interior is filled with distilled water. When the copper sheet 102 absorbs heat, the distilled water at one end of the heat pipe near the copper sheet 102 is heated and vaporized. Due to the connected structure, the steam can flow freely in the entire heat pipe network and quickly transfer the heat to other parts of the heat sink; the copper sheet 102, the vertical heat pipe 103, and the horizontal heat pipe 104 are all integrated, and the vertical heat pipe 103 and the horizontal heat pipe 104 constitute a connected structure, and distilled water is provided inside the vertical heat pipe 103 and the horizontal heat pipe 104.

[0028] See also Figure 3 As shown in the combined copper-embedded heat sink, the fixing component 2 includes a snap-fit ​​groove 201, a snap-fit ​​frame 202 is fixedly connected to the side of the snap-fit ​​groove 201, and a nut 203 is fixedly connected to the outer wall of the snap-fit ​​frame 202, and the internal thread of the nut 203 is connected to the bolt 204. The nut 203 and the bolt 204 form a threaded structure and the two are arranged with a vertical center axis. This design allows the heat sink to accurately adjust its position by rotating the bolt 204 during installation. The nut 203 and the bolt 204 form a threaded structure and the two are arranged with a vertical center axis. This design allows the heat sink to accurately adjust its position by rotating the bolt 204 during installation. The snap-fit ​​groove 201, the snap-fit ​​frame 202, and the nut 203 are all integrated, and the nut 203 and the bolt 204 are arranged with a vertical center axis, and the nut 203 and the bolt 204 form a threaded structure.

[0029] See also Figure 4As shown, the combined frame assembly 3 includes a vertical rod 303, with a slot 304 defined on the side of the vertical rod 303. A buckle 302 is engaged within the slot 304, and a crossbar 301 is fixedly connected to the side of the buckle 302. The crossbar 301 forms a snap-fit ​​structure with the vertical rod 303 through the buckle 302 and the slot 304. This snap-fit ​​structure greatly improves the convenience of assembly and disassembly. When assembling the heat sink on the production line, the operator can easily engage the crossbar 301 with the slot 304 of the vertical rod 303 through the buckle 302, eliminating the need for complex connection processes and tools, thereby improving production efficiency. Moreover, when the equipment is repaired or the heat sink is replaced, the combined frame can be quickly disassembled to facilitate operation of the heat sink. At the same time, the locking structure can maintain good stability under normal use to ensure the normal operation of the heat sink; the cross bar 301 and the buckle 302 are integrated, and the cross bar 301 forms a locking structure through the buckle 302, the slot 304 and the vertical bar 303.

[0030] The working principle of this embodiment is as follows: first, the frame assembly 3 is assembled, the cross bar 301 and the buckle 302 are integrated, and the cross bar 301 forms a snap-fit ​​structure with the snap groove 304 on the side of the vertical bar 303 through the buckle 302. During the assembly process, the buckle 302 is aligned with the slot 304 on the vertical bar 303 and inserted, and then slid forward to snap and fix it, thereby completing the connection between the cross bar 301 and the vertical bar 303. This snap-fit ​​structure makes the assembly of the combined frame very convenient. The snap-fit ​​frame 202 is put on the cross bar 301, and the fixing assembly 2 is assembled through the snap groove 201, the snap frame 202, the nut 203 and the bolt 204 to achieve alignment. To fix the heat sink, the snap-fit ​​groove 201 is used for preliminary positioning and placement of the heat sink, and the snap-fit ​​frame 202 increases the contact area and stability with the installation plane or equipment. When the heat sink needs to be fixed, the bolt 204 is tightened through the threaded connection with the nut 203. Since the nut 203 and the bolt 204 are arranged with a vertical central axis, during the tightening process, the pressure exerted by the bolt 204 is evenly distributed on the fixing component 2, so that the heat sink is firmly fixed in the specified position. This integrated snap-fit ​​groove 201, snap-fit ​​frame 202, and nut 203 structure ensures that the components will not be relatively displaced or loosened during the fixing process, thereby ensuring the stability of the fixation.

[0031] When the heat sink is working, heat is first transferred from the heat source to the heat sink body 101. Since the copper sheet 102 is fixedly connected to the side of the heat sink body 101, the high thermal conductivity of copper allows the heat to be quickly absorbed by the copper sheet 102. Then, the heat on the copper sheet 102 is transferred to the vertical heat pipe 103 and the horizontal heat pipe 104 connected to it. Because the copper sheet 102, the vertical heat pipe 103, and the horizontal heat pipe 104 are integrated, the contact thermal resistance during the heat transfer process is extremely small, which can achieve efficient heat conduction. The connecting structure formed by the vertical heat pipe 103 and the horizontal heat pipe 104 plays a key role. Inside the heat pipe, the distilled water near the copper sheet 102, that is, the heat source end, is heated and vaporized to form steam. Due to the connecting structure, the steam can flow freely in the network formed by the vertical heat pipe 103 and the horizontal heat pipe 104, quickly transferring the heat to other parts of the heat sink, so that the heat is more evenly diffused over the entire heat sink, effectively avoiding local overheating and improving the heat dissipation efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
