[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A high-efficiency heat sink, such as Figure 1 As shown, the heat sink body 1 is made of aluminum alloy. The lightweight and high strength of aluminum alloy ensures the strength and service life of the heat sink body 1. Aluminum alloy has good thermal conductivity, so when the heat sink body 1 is fixed against the heat-generating device, it can conduct heat from the heat-generating device to the heat sink body 1 through good heat transfer, thereby reducing the temperature inside the heat-generating device.

[0019] like Figure 1 and Figure 2 As shown, a U-shaped heat dissipation chamber 2 is provided on one side of the length of the radiator body 1. The heat dissipation chamber 2 is made of aluminum alloy plate by bending it with a bending machine. A rectangular ventilation slot 3 is opened along the length of the heat dissipation chamber 2. The ventilation slot 3 is integrally formed by bending the heat dissipation chamber 2. The ventilation slot 3 allows air to circulate between the inside and outside of the heat dissipation chamber 2. Four rectangular snap-fit ​​slots 7 are opened through the length of the heat dissipation chamber 2 near the heat-generating device and are interconnected with the ventilation slots 3. Each of the four snap-fit ​​slots 7 is provided with a rectangular heat-conducting plate 8. The length, width and thickness of the heat-conducting plate 8 are the same as the length, width and depth of the snap-fit ​​slot 7, so that the heat-conducting plate 8 can be snapped into the snap-fit ​​slot 7. The heat-conducting plate 8 is made of copper. Copper has strong thermal conductivity. When the four heat-conducting plates 8 come into contact with the heat-generating device, they can quickly dissipate the heat inside the heat-generating device, further improving the cooling speed of the heat dissipation body 1 for the heat-generating device.

[0020] like Figure 1 and Figure 2As shown, a rectangular fixing plate 4 and a rectangular guide plate 5 are fixedly connected to both ends of the width of the heat dissipation chamber 2 by welding. Both the fixing plate 4 and the guide plate 5 are made of aluminum alloy. The guide plate 5 is inclined along the side away from the heat dissipation chamber 2, so that the fixing plate 4 and the guide plate 5 on the same side of the heat dissipation chamber 2 form a guide space 6 that is connected to the ventilation slot 3. The guide space 6 on both sides of the heat dissipation chamber 2 can guide the airflow from the outside to flow in the ventilation slot 3, so that the ventilation slot 3 has a good air circulation effect, thereby quickly removing the heat from the heat dissipation chamber 2 and the four heat conduction plates 8, ensuring the continuous cooling effect of the heat dissipation chamber 2 and the heat conduction plates 8 on the heat-generating equipment.

[0021] like Figures 1-3 As shown, three rectangular aluminum alloy mounting plates 9 are fixedly connected to the side of the heat dissipation chamber 2 away from the mounting slot 7 by welding. Four rectangular ventilation slots 2 10 and four rectangular mounting slots 2 11 are cut in an alternating pattern on one side of the mounting plates 9 using a cutting machine. The four mounting slots 2 11 and four ventilation slots 2 10 on the three mounting plates 9 are symmetrically arranged along the length of the heat dissipation chamber 2. The length of the heat dissipation fins 12 is greater than the length of the heat dissipation chamber 2, so that each of the four symmetrically arranged mounting slots 2 11 on the three mounting plates 9 contains a heat dissipation fin 1 made of aluminum alloy. 2. The heat dissipation fins 12 are wavy after being bent by a bending machine, which increases the surface area of ​​the heat dissipation fins 12. Some of the heat absorbed by the heat dissipation chamber 2 and the heat conduction plate 8 will be transferred to the four heat dissipation fins 12 through heat transfer. The four heat dissipation fins 12 increase the contact area between the heat sink body 1 and the air. When the air near the heat dissipation fins 12 is heated, its volume will expand and its density will decrease. Therefore, the relatively lighter hot air will rise and the cooler air will sink, thus forming air convection that carries away the temperature on the heat dissipation fins 12 and improves the heat dissipation effect of the heat sink body 1.

[0022] like Figure 2 and Figure 3 As shown, the openings of the second ventilation slot 10 and the second snap-fit ​​slot 11 face upwards to prevent the heat dissipation fins 12 snapped into the second snap-fit ​​slot 11 from falling off. The width and thickness of the heat dissipation fins 12 are the same as the depth and width of the second snap-fit ​​slot 11 and are less than the length of the snap-fit ​​plate 9. While ensuring the strength of the snap-fit ​​plate 9, a larger heat dissipation fin 12 can be installed. At the same time, it is convenient to install and remove the heat dissipation fins 12. The heat dissipation fins 12 can be removed periodically for cleaning to prevent dust and debris from accumulating on the heat dissipation fins 12 and hindering the heat transfer, thus ensuring the long-lasting heat dissipation effect of the heat dissipation fins 12.

[0023] like Figures 1-3As shown, a second airflow space 13 is formed between the guide plate 5 and its adjacent snap-fit ​​plate 9. A ventilation space 14 is formed between adjacent heat dissipation fins 12, which is interconnected with the ventilation slot 10 and the second airflow space 13. A second ventilation space 15 is formed between the heat dissipation chamber 2 and its adjacent heat dissipation fins 12, which is interconnected with the ventilation slot 10 and the second airflow space 13. The airflow space 13 on both sides of the radiator body 1 can guide the external airflow between the four heat dissipation fins 12, improving the airflow effect between adjacent heat dissipation fins 12, thereby further enhancing the heat dissipation performance of the heat dissipation fins 12. The width of the ventilation slot 10 is greater than the width of the snap-fit ​​slot 11. The wider ventilation slot 10 is more conducive to the airflow effect between adjacent heat dissipation fins 12, thereby achieving the effect of continuous and efficient heat dissipation of the radiator body 1.

[0024] like Figure 1 and Figure 2 As shown, a number of circular mounting holes 16 are drilled through both sides of the heat dissipation chamber 2 and the fixing plate 4 using a drilling machine. The mounting holes 16 are symmetrically arranged on both sides of the heat dissipation chamber 2 along its width direction. The radiator body 1 can be fixed to the outer wall of the heat-generating device through the mounting holes 16. A base plate 17 made of aluminum alloy is provided at the bottom of the heat dissipation chamber 2. The length and width of the base plate 17 are the same as the length and width of the ventilation slot 3, respectively. The base plate 17 is fixedly connected to the bottom of the heat dissipation chamber 2 by welding. The top surface of the base plate 17 is an arc-shaped protrusion. The base plate 17 allows air to circulate in the ventilation slot 3 and can also remove moisture and debris from the heat dissipation chamber 2, so as to avoid clogging the ventilation slot 3 and affecting the heat dissipation effect.

[0025] Working principle: An aluminum alloy plate is bent into a U-shaped heat dissipation chamber 2. Four snap-fit ​​grooves 7 are cut on the side of the heat dissipation chamber 2 closest to the heat-generating device. Four heat-conducting plates 8 are snapped into the four snap-fit ​​grooves 7 respectively. Two fixing plates 4 and two guide plates 5 are welded to both sides of the width of the heat dissipation chamber 2 respectively. Before welding the guide plates 5, the angle of the guide plates 5 along the side away from the heat dissipation chamber 2 is adjusted. The base plate 17 is welded to the bottom of the heat dissipation chamber 2. Four snap-fit ​​grooves 11 and four ventilation grooves 10 are cut on three snap-fit ​​plates 9 and then welded to the side of the heat dissipation chamber 2 away from the snap-fit ​​grooves 7. Several mounting holes 16 are drilled on the two fixing plates 4 and the heat dissipation chamber 2. The heat dissipation chamber 2 and the heat dissipation chamber 2 are connected through the mounting holes 16. Two fixed plates 4 are fixed against the outer wall of the heating device, and the heat is dissipated through heat transfer. The interconnected flow guide space 6 and ventilation slot 3 ensure good air circulation in the heat dissipation chamber 2, thereby continuously reducing the temperature in the heat dissipation chamber 2 and the heat conduction plate 8. Four heat dissipation fins 12 are snapped into the snap-fit ​​slots 11 on the three snap-fit ​​plates 9. The four heat dissipation fins 12 increase the contact area between the radiator body 1 and the air to improve the heat dissipation effect. The interconnected flow guide space 13, ventilation space 14 and ventilation space 15 ensure good air circulation between adjacent heat dissipation fins 12, thereby continuously reducing the temperature of the heat dissipation fins 12.
