Example
[0026] See also Figure 1-7 The utility model provides a technical solution: a heat sink that is easy to use, including a heat sink body 1 and a water cooling mechanism. The main body of the heat sink body 1 is made of aluminum alloy and has good thermal conductivity. In order to facilitate the connection and installation of the heat sink body 1, mounting screw holes 8 are evenly opened on the side of the heat sink body 1. Mounting bolts are arranged inside the mounting screw holes 8. The heat sink body 1 is fixed to the upper part of the equipment bracket by the mounting bolts.
[0027] In order to facilitate the connection and installation of the circuit board, a mounting support 4 is provided on the upper part of the heat dissipation plate body 1. The circuit board is mounted on the upper part of the mounting support 4 by bolts. In order to facilitate the heat dissipation by fitting with the components on the upper part of the circuit board, as shown in the attached figure, Figure 1 As shown, a cavity boss 2 is provided on the upper part of the heat dissipation plate body 1. There are multiple cavity bosses 2. Several cavity bosses 2 are fixedly provided on the upper part of the heat dissipation plate body 1 according to the distribution of components on the upper part of the circuit board. In order to facilitate the conduction of heat and the fitting support of the components, a thermal conductive adhesive pad 3 is provided on the upper part of the cavity boss 2. The thermal conductive adhesive pad 3 is a soft thermal conductive patch. The thermal conductive adhesive pad 3 is fixedly fitted on the upper part of the cavity boss 2. The components on the upper part of the circuit board are in contact with the thermal conductive adhesive pad 3. The distance h from the surface of the heat generating device to the bottom is calculated by the height of the circuit board mounting surface and the heat generating device. Because the height of the component itself has an error range, when soldered on the circuit board There is also a certain error, so the value of "distance h" has a certain fluctuation range. In order to achieve the purpose of heat conduction for all heating devices, a thermally conductive adhesive pad 3 is added between the heating device and the cavity boss 2. The thermally conductive adhesive pad 3 has a certain amount of compression, which ensures that the heating device, the thermally conductive adhesive pad 3 and the cavity boss 2 are tightly fitted. The size of the cavity boss 2 is the same as the size of the heating device. It can be larger than the size of the heating device without interfering with other devices on the circuit board. After installation, the cavity boss 2 and the heating device are fitted accordingly, which can realize the overall conduction and heat dissipation of the components on the upper part of the circuit board. The heat dissipation structure is installed integrally with the circuit board body, which is easy to install.
[0028] The water cooling mechanism includes a liquid supply conduit 9, a water cooler 10 and a heat dissipation auxiliary component 11. In order to facilitate the circulation of water-cooled liquid and heat dissipation, a water cooling groove 5 is provided inside the heat dissipation plate body 1. The heat dissipation plate body 1 is divided into two parts, the upper and lower parts, and the two parts of the water cooling groove 5 are fixedly connected to form an integrated plate seat structure. The water cooling groove 5 is opened in the middle of the sandwich of the upper and lower parts of the heat dissipation plate body 1. The water cooling groove 5 is processed on the aluminum plate by a machining center according to a certain route. The route passes through the heating device or is close to the bottom of the heating device. After the processing is completed, the water cooling groove 5 is welded into shape by friction welding. In order to facilitate the connection of the water cooler 10, as shown in the attached figure Figure 2 As shown, the side of the heat dissipation plate body 1 is provided with a liquid inlet interface 6 and a return interface 7, which are respectively connected to the two opening sides of the water cooling tank 5, and the distance between the liquid inlet interface 6 and the return interface 7 is about 40 to 60 mm. The liquid inlet interface 6 and the return interface 7 are respectively connected to the liquid outlet and the liquid inlet of the water cooling machine 10 through the liquid supply pipe 9. When the water cooling machine 10 is started during operation, the cooling liquid flows in the water cooling tank 5 and takes the heat out of the cavity through heat transfer. The heat transfer path is shown in the attached figure. Figure 4 As shown, the water cooling groove 5 is opened near the cavity boss 2 according to the component distribution, which can facilitate the water cooling liquid to take away the heat inside the cavity boss 2 and effectively improve the heat dissipation efficiency of the board.
[0029] The heat dissipation auxiliary component 11 includes a sealing edge seat 12 and a heat dissipation guide seat 13. The heat dissipation guide seat 13 is made of aluminum alloy. Figure 6 As shown, the number of sealing edge seats 12 is two, and the heat dissipation guide seat 13 is fixed and clamped in the middle of the two sealing edge seats 12 by bolts. In order to improve the sealing of the connection, a sealing ring gasket 17 is fixed on the edge installation side of the sealing edge seat 12. In order to facilitate the connection and installation with the liquid supply conduit 9, a conduit interface 14 is provided in the middle of the side of the two sealing edge seats 12. The conduit interface 14 is fixedly connected with the end of the return side liquid supply conduit 9. The heat dissipation guide seat 13 is connected and installed in the middle of the return side liquid supply conduit 9 through the sealing edge seat 12. In order to accelerate the conduction of heat, guide holes 16 are evenly provided in the middle of the heat dissipation guide seat 13, as shown in the attached figure. Figure 7 As shown, the middle part of the guide hole 16 is a semicircular turning mouth, and the guide hole 16 is evenly opened in the middle of the heat dissipation guide seat 13 in a circular shape. The guide hole 16 set in the middle of the heat dissipation guide seat 13 is used to divert and guide the water-cooling liquid, thereby increasing the contact area between the heat dissipation guide seat 13 and the water-cooling liquid. In order to accelerate the conduction and dissipation of heat, heat dissipation fins 15 are evenly arranged on the outer circumference of the heat dissipation guide seat 13. The heat dissipation fins 15 are evenly fixed on the outer circumference of the heat dissipation guide seat 13 in a circular shape. The heat dissipation of the water-cooling liquid is assisted by the heat dissipation guide seat 13 and the heat dissipation fins 15, which can reduce the temperature of the reflux water-cooling liquid and improve the heat dissipation efficiency of the heat sink.
[0030] Working principle or structural principle, when installing, fix the heat sink body 1 through the mounting screw holes 8, then mount the circuit board on the upper part of the heat sink body 1 through the mounting pillars 4 with the bolts, and ensure that the components on the upper part of the circuit board are aligned with the thermal conductive adhesive pad 3 on the upper part of the cavity boss 2 during installation, and then connect the end of the liquid supply conduit 9 to the corresponding interface on the side of the heat sink body 1. When connecting, the air in the water cooling tank 5 must be discharged by slowly supplying liquid to complete the installation operation of the device. When working, the heat generated by the components on the upper part of the circuit board is conducted to the cavity boss 2 through the thermal conductive adhesive pad 3, and the water cooling The liquid is transported by the water-cooling machine 10 from the liquid supply pipe 9 into the water-cooling tank 5. Under the circulation and conduction of the water-cooling liquid, the heat is carried by the water-cooling liquid and flows out through the reflux interface 7. When the water-cooling liquid flows through the heat dissipation auxiliary component 11, the diverted water-cooling liquid through the guide hole 16 flows through the heat dissipation guide seat 13 through the guide hole 16. During the circulation process, the heat is conducted to the heat dissipation fins 15, and then dissipated to the outside through the heat dissipation fins 15, thereby realizing auxiliary heat dissipation of the return water-cooling liquid. After that, the water-cooling liquid flows back to the water-cooling machine 10, and after further cooling and recovery, it is re-delivered to the heat dissipation plate body 1 through the liquid supply pipe 9 to complete the heat dissipation cycle.
