Description

Technical Field

[0001] The utility model relates to the technical field of copper-aluminum composite heat sinks, and specifically relates to a copper-aluminum composite heat sink with a porous structure. Background Technique

[0002] The copper-aluminum composite heat sink is a radiator made by combining the respective advantages of copper and aluminum. The copper-aluminum composite heat sink usually adopts a "double water channel" design, making the heat dissipation effect more ideal, and the heat dissipation capacity is 80% higher than that of traditional single water channel radiators. Due to the very good thermal conductivity of copper and aluminum, the heat dissipation capacity of copper-aluminum radiators is much higher than that of radiators made of other materials. Secondly, aluminum alloy profiles have high strength, good water tightness and air tightness, and good heat conduction. With its excellent performance, the copper-aluminum composite heat sink has been widely used in heating systems, electronic devices, automobile engines and other fields.

[0003] For example, the Chinese patent "A Copper-Aluminum Composite Heat Sink with a Porous Structure" with the publication number CN208846995U includes a mounting back plate, a first protection plate, a second rotating shaft, a positioning groove and an adsorption magnet. The surface of the mounting back plate is provided with a copper-aluminum composite heat sink, and the surface of the copper-aluminum composite heat sink is provided with heat dissipation holes. The end of the mounting back plate is fixedly welded with a shock-absorbing base, and the outer wall of the mounting back plate is provided with a first rotating shaft. The first protection plate is mounted on the outer wall of the first rotating shaft. The second rotating shaft is mounted on the upper end of the mounting back plate, and the upper end of the second rotating shaft is provided with a second protection plate. Connecting rods are fixedly welded to the rear ends of the first protection plate and the second protection plate, and positioning blocks are fixedly welded to the ends of the connecting rods. The positioning groove is arranged on the rear side surface of the mounting back plate, and a water pipe is installed inside the copper-aluminum composite heat sink.

[0004] Although the above-mentioned prior art can achieve heat dissipation through the copper-aluminum composite heat sink, in actual use, on the one hand, the disassembly and assembly of the copper-aluminum composite heat sink are not convenient enough. When a certain part of the copper-aluminum composite heat sink is damaged, the whole copper-aluminum composite heat sink needs to be removed, resulting in the need to repair the whole copper-aluminum composite heat sink, thereby increasing the maintenance cost of the copper-aluminum composite heat sink. On the other hand, the heat dissipation is not fast enough. When dissipating heat, it is dissipated by the self-thermal radiation of the copper-aluminum composite heat sink, resulting in a slow heat dissipation rate. Therefore, it does not meet the existing requirements. For this reason, we propose a copper-aluminum composite heat sink with a porous structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a copper-aluminum composite heat sink with a porous structure to solve the problems of inconvenient disassembly and assembly of the copper-aluminum composite heat sink and slow heat dissipation rate proposed in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A copper-aluminum composite heat sink with a porous structure, including a base, and there are two bases. Bolts are provided at the front and rear ends of the base, and the bolts extend into the interior of the wall, and the bolts are threadedly connected to the wall; further included are:

[0007] A first mounting seat, which is arranged on one side close to the upper base, and the first mounting seat is connected to the base by welding. A third mounting seat is arranged on one side close to the lower base, and the third mounting seat is connected to the base by welding. On one side of the lower end of the first mounting seat and one side of the upper end of the third mounting seat, connecting plates are fixedly provided, and a second mounting seat is fixedly arranged between the connecting plates. Positioning holes are arranged at the middle positions inside the first mounting seat, the second mounting seat, and the third mounting seat.

[0008] Preferably, a hot water pipe is arranged inside the positioning hole, and the hot water pipe penetrates through the positioning hole. Four limiting strips are fixedly arranged on the outer part of the hot water pipe, the limiting strips are annularly distributed, and the limiting strips are slidably limited with the positioning hole.

[0009] Preferably, a plurality of heat dissipation fins are fixedly arranged at the middle positions between the third mounting seat and the first mounting seat and the second mounting seat respectively, and the heat dissipation fins are equidistantly distributed.

[0010] Preferably, a plurality of first ventilation holes are arranged inside the heat dissipation fins, and the first ventilation holes are equidistantly distributed. On one side of the heat dissipation fin close to the middle position of the connecting plate, an installation groove is arranged.

[0011] Preferably, a rotating rod is arranged on one side of the connecting plate, and the rotating rod is rotatably connected to the connecting plate. A fan blade is fixedly arranged on the outer part of the rotating rod located inside the installation groove.

[0012] Preferably, a motor is fixedly arranged on the other side of the connecting plate, and the output shaft of the motor extends to one side of the connecting plate and is fixedly connected to the rotating rod.

[0013] Preferably, a shielding plate is fixedly arranged on the other side between the third mounting seat and the first mounting seat and the second mounting seat respectively. A plurality of second ventilation holes are arranged inside the shielding plate, and the second ventilation holes are equidistantly distributed.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. The utility model can quickly disassemble and assemble the copper-aluminum composite heat sink through the positioning holes and the limiting strips. When a certain part of the copper-aluminum composite heat sink is damaged, first rotate the bolt so that the bolt moves outward through the external thread until the bolt detaches from the base. At this time, push the first mounting seat, so that the first mounting seat drives the second mounting seat and the third mounting seat to slide on the hot water pipe until the copper-aluminum composite heat sink is removed from the hot water pipe and the damaged copper-aluminum composite heat sink is replaced. When installing the copper-aluminum composite heat sink, first align the opening of the positioning hole with the hot water pipe and push the first mounting seat, so that the positioning hole is engaged with the limiting strip and the sliding of the first mounting seat is maintained until the installation of the copper-aluminum composite heat sink is completed. At this time, rotate the bolt again so that the bolt moves into the wall through the external thread until the bolt moves to a suitable position and then fixes the copper-aluminum composite heat sink, thus simplifying the disassembly and assembly steps of the copper-aluminum composite heat sink and improving the maintenance efficiency of the copper-aluminum composite heat sink.

[0016] 2. The utility model can accelerate the heat dissipation efficiency through the fan blades and the motor. When dissipating heat, turn on the motor at this time, so that the output shaft of the motor drives the rotating rod to rotate. Through the rotating rod, the fan blades fixedly connected thereto rotate. At this time, the air near the fan blades is in a negative pressure state. Through the negative pressure, the air is accelerated to pass through the fan blades and form an air flow. At the same time, the heat on the hot water pipe is transferred to the heat dissipation fins through the first mounting seat, the second mounting seat and the third mounting seat. When the air flow passes through the heat dissipation fins, the air flow with a lower temperature absorbs the heat on the heat dissipation fins, so that the temperature of the air flow rises and the air flow with a higher temperature is blown out of the inside of the copper-aluminum composite heat sink, thus improving the heat dissipation efficiency.

[0017] 3. The utility model can improve the ventilation inside the copper-aluminum composite heat sink through the first ventilation holes and the second ventilation holes. When dissipating heat, the air flow generated by the fan blades can pass through the first ventilation holes provided on the heat dissipation fins, so that the heat on the heat dissipation fins is more fully transferred to the air flow. At the same time, the air flow with heat is blown out through the second ventilation holes on the baffle, increasing the temperature in the use environment. By reducing the blockage of the air flow through the second ventilation holes, the ventilation inside the copper-aluminum composite heat sink is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please refer to Figures 1-4 , an embodiment provided by the present invention: a copper-aluminum composite heat sink with a porous structure, including a base 1, and there are two bases 1. Bolts 16 are provided at the front and rear ends of the base 1, and the bolts 16 extend into the wall, and the bolts 16 are threadedly connected to the wall; it also includes:

Positioning holes 15 are arranged at the middle positions inside the first mounting seat 3, the second mounting seat 4, and the third mounting seat 5.

[0026] During use, when a certain part of the copper-aluminum composite heat sink is damaged, first rotate the bolt 16 so that the bolt 16 moves outward through the external thread until the bolt 16 detaches from the base 1. At this time, push the first mounting seat 3 so that the first mounting seat 3 drives the second mounting seat 4 and the third mounting seat 5 to slide on the hot water pipe 11 until the copper-aluminum composite heat sink is removed from the hot water pipe 11 and the damaged copper-aluminum composite heat sink is replaced. When installing the copper-aluminum composite heat sink, first align the opening of the positioning hole 15 with the hot water pipe 11 and push the first mounting seat 3 so that the positioning hole 15 is engaged with the limit strip 2 and keep the first mounting seat 3 sliding until the copper-aluminum composite heat sink is installed. At this time, rotate the bolt 16 again so that the bolt 16 moves into the wall through the external thread until the bolt 16 moves to a suitable position and then fixes the copper-aluminum composite heat sink.

[0027] Please refer to Figure 1 and Figure 3, a hot water pipe 11 is arranged inside the positioning hole 15, and the hot water pipe 11 penetrates through the positioning hole 15. Four limiting strips 2 are fixedly arranged outside the hot water pipe 11. The limiting strips 2 are annularly distributed, and the limiting strips 2 are slidably limited with the positioning hole 15, which is convenient for the installation of the copper-aluminum composite heat sink to be more stable through the positioning hole 15.

[0028] Please refer to Figure 1 and Figure 2 , a plurality of heat dissipation fins 6 are fixedly arranged at the middle positions between the third mounting seat 5 and the first mounting seat 3 and the second mounting seat 4 respectively, and the heat dissipation fins 6 are equidistantly distributed, which is convenient for absorbing the heat on the third mounting seat 5, the first mounting seat 3 and the second mounting seat 4 through the heat dissipation fins 6.

[0029] Please refer to Figure 1 , a plurality of first ventilation holes 7 are arranged inside the heat dissipation fins 6, and the first ventilation holes 7 are equidistantly distributed. An installation groove 14 is arranged on one side of the heat dissipation fins 6 close to the middle position of the connecting plate 17, which is convenient for the air flow to better absorb the heat on the heat dissipation fins 6 through the first ventilation holes 7.

[0030] Please refer to Figure 1 and Figure 2 , a rotating rod 9 is arranged on one side of the connecting plate 17, and the rotating rod 9 is rotatably connected with the connecting plate 17. A fan blade 8 is fixedly arranged outside the rotating rod 9 inside the installation groove 14, which is convenient for accelerating the air circulation inside the copper-aluminum composite heat sink through the fan blade 8.

[0031] Please refer to Figure 1 and Figure 2 , a motor 10 is fixedly arranged on the other side of the connecting plate 17, and the output shaft of the motor 10 extends to one side of the connecting plate 17 and is fixedly connected with the rotating rod 9, which is convenient for driving the fan blade 8 to rotate through the motor 10.

[0032] Please refer to Figure 1 , a shielding plate 12 is fixedly arranged on the other side between the third mounting seat 5 and the first mounting seat 3 and the second mounting seat 4 respectively. A plurality of second ventilation holes 13 are arranged inside the shielding plate 12, and the second ventilation holes 13 are equidistantly distributed, which is convenient for increasing the stability of the copper-aluminum composite heat sink through the shielding plate 12.

[0033] Working principle: When heat dissipation is carried out, the motor 10 is turned on at this time, so that the output shaft of the motor 10 drives the rotating rod 9 to rotate. Through the rotating rotating rod 9, the fan blade 8 fixedly connected thereto rotates. At this time, the air near the fan blade 8 is in a negative pressure state. Through the negative pressure, the air is accelerated to pass through the fan blade 8 and form an air flow. At the same time, the heat on the hot water pipe 11 is transferred to the heat dissipation fins 6 through the first mounting seat 3, the second mounting seat 4 and the third mounting seat 5. When the air flow passes through the heat dissipation fins 6, the relatively low-temperature air flow absorbs the heat on the heat dissipation fins 6, causing the temperature of the air flow to rise and blowing out the relatively high-temperature air flow from the inside of the copper-aluminum composite heat sink. When heat dissipation is carried out, the air flow generated by the fan blade 8 can pass through the first ventilation holes 7 provided on the heat dissipation fins 6, so that the heat on the heat dissipation fins 6 is more fully transferred to the air flow. At the same time, the air flow with heat is blown out through the second ventilation holes 13 on the baffle plate 12, increasing the temperature in the use environment.
