Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, and in particular to a high thermal conductivity aluminum-magnesium alloy heat sink structure. Background Technology

[0002] A heatsink is a device used to dissipate heat from heat-generating electronic components in electrical appliances. It is typically made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. For example, the CPU (Central Processing Unit) in a computer requires a fairly large heatsink, and power transistors, horizontal output transistors, and power amplifier transistors in a television all use heatsinks. Generally, a layer of thermal grease is applied to the contact surface between the electronic component and the heatsink during use. This allows the heat generated by the component to be more effectively conducted to the heatsink, and then dissipated into the surrounding air.

[0003] In the existing technology, heat sinks are made of different materials depending on the actual needs. Aluminum-magnesium alloy heat sinks have the characteristics of high thermal conductivity, low density, high strength, and corrosion resistance. Currently, heat sinks are all integrally molded. After long-term use, impurities such as willow catkins or dust will accumulate inside. The distance between the heat dissipation fins in the heat sink is small, and cleaning can only be done by adsorption or airflow blowing, which is inconvenient and difficult to clean in practice. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, heat sinks use different materials depending on the actual needs. Aluminum-magnesium alloy heat sinks have the characteristics of high thermal conductivity, low density, high strength, and corrosion resistance. Currently, heat sinks are all integrally molded. After long-term use, impurities such as willow catkins or dust will accumulate inside. The distance between the heat dissipation fins in the heat sink is small, and cleaning can only be done by adsorption or airflow blowing, which is inconvenient and difficult to clean in practice. Therefore, a high thermal conductivity aluminum-magnesium alloy heat sink structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high thermal conductivity aluminum-magnesium alloy heat sink structure, including a thermally conductive base plate, a first slot opened at the upper end of the thermally conductive base plate, a heat sink fin inserted into the first slot, a limiting end frame provided at the upper end of the heat sink fin, a bottom extension frame fixedly connected at the lower end of the limiting end frame, an inner limiting rod fixedly connected inside the bottom extension frame, a second slot opened at the lower end of the bottom extension frame and the inner limiting rod, and the second slot being inserted into the upper end of the heat sink fin.

[0006] Preferably, the lower end face of the inner limiting rod is arc-shaped, and both ends of the heat dissipation fins are fixedly connected with circular end strips.

[0007] Preferably, mounting holes are provided at all four corners of the heat-conducting base plate.

[0008] Preferably, a threaded rod is fixedly connected to each of the four corners of the upper end of the limiting end frame.

[0009] Preferably, each of the four corners at the lower end of the limiting end frame is fixedly connected with a No. 2 threaded rod.

[0010] Preferably, a hexagonal prism is provided between the four corners of the heat-conducting base plate and the limiting end frame, and threaded grooves are provided at the upper and lower ends of the hexagonal prism.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the heat dissipation fins are installed by plugging into the heat-conducting base plate through the No. 1 slot. The upper end of the heat dissipation fins is restricted by the inner limiting rod to ensure stability during use. In this way, the heat dissipation fins are designed to be detachable, so that they can be removed and cleaned separately when cleaning is required. This is convenient to use and cleans more thoroughly. At the same time, this design allows the heat dissipation fins to be replaced separately when they are bent, reducing maintenance costs.

[0012] 2. In this utility model, the circular end bar is used to increase the contact area between the heat-conducting base plate and the bottom extension frame, thereby increasing the connection stability. At the same time, it can increase the strength of the heat dissipation fins, making the heat dissipation fins less prone to bending and increasing the service life. The arc surface design at the lower end of the inner limit rod can reduce wind resistance, avoid airflow affecting the limit end frame, and ensure the stability of use. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-5 As shown, this utility model provides a high thermal conductivity aluminum-magnesium alloy heat sink structure, including a thermally conductive base plate 1. A first slot 8 is opened at the upper end of the thermally conductive base plate 1. A heat sink fin 4 is inserted into the first slot 8. A limiting end frame 2 is provided at the upper end of the heat sink fin 4. A bottom extension frame 10 is fixedly connected to the lower end of the limiting end frame 2. An inner limiting rod 3 is fixedly connected to the inside of the bottom extension frame 10. A second slot 12 is opened at the lower end of the bottom extension frame 10 and the inner limiting rod 3. The second slot 12 is inserted into the upper end of the heat sink fin 4.

[0018] The specific settings and functions of this embodiment are described in detail below. Through the setting of slot 8, the heat dissipation fins 4 are installed with the heat conduction base plate 1 by plugging in. The upper end of the heat dissipation fins 4 is restricted by the inner limiting rod 3 to ensure stability during use. In this way, the heat dissipation fins 4 are designed to be detachable, so that the heat dissipation fins 4 can be removed and cleaned separately when cleaning is required. It is more convenient to use and cleaner. At the same time, this design allows the heat dissipation fins 4 to be replaced separately when they are bent, reducing maintenance costs.

[0019] Example 2: Figures 1-5 As shown, the lower end face of the inner limiting rod 3 is arc-shaped, and both ends of the heat dissipation fins 4 are fixedly connected with circular end strips 9. The four corners of the heat-conducting base plate 1 are provided with mounting holes 7. The four corners of the upper end of the limiting end frame 2 are fixedly connected with threaded rods 6 of the first type, and the four corners of the lower end of the limiting end frame 2 are fixedly connected with threaded rods 11 of the second type. A hexagonal prism 5 is provided between the four corners of the heat-conducting base plate 1 and the limiting end frame 2. The upper and lower ends of the hexagonal prism 5 are provided with threaded grooves 13. The threaded rod 6 of the first type is used to install the fan, the mounting holes 7 are used to insert the bolts required for the installation of the heat-conducting base plate 1, and the threaded grooves 13 at both ends of the hexagonal prism 5 are used to install the bolts required for the second threaded rod 11 to be fixed to the heat-conducting base plate 1.

[0020] The overall effect of this embodiment is that by setting the circular end bar 9, the contact area between it and the heat-conducting base plate 1 and the bottom extension frame 10 is increased, thereby increasing the connection stability. At the same time, it can increase the strength of the heat dissipation fins 4, making the heat dissipation fins 4 less prone to bending and increasing the service life. The arc surface design at the lower end of the inner limit rod 3 can reduce wind resistance, prevent airflow from affecting the limit end frame 2, and ensure the stability of use.

[0021] The usage method and working principle of this device are as follows: Place the heat-conducting base plate 1 in the installation area and place the screw in the installation hole 7. Then assemble the heat dissipation fins 4, the limiting end frame 2 and the first slot 8. During this process, place the hexagonal prism 5 between the heat-conducting base plate 1 and the limiting end frame 2. By rotating the hexagonal prism 5, the heat-conducting base plate 1 is fixed and the limiting end frame 2 is limited to the upper end of the heat dissipation fins 4, thus completing the installation and fixing. Then, according to the requirements, place the first threaded rod 6 at the upper end of the limiting end frame 2 into the installation hole of the fan and install the fan and the limiting end frame 2.
