Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5This utility model provides an embodiment of a brushless motor diamond heat sink, including a heat dissipation device 1 and a protective device 2. The protective device 2 is disposed on the heat dissipation device 1. The heat dissipation device 1 includes a heat-conducting arc plate 3, a mounting plate 4, a heat sink 5, a locking block 6, a mounting base 7, a plug-in groove 8, and a locking plate 9. The mounting plate 4 is symmetrically fixedly connected to the bottom ends of both sides of the heat-conducting arc plate 3. The mounting base 7 is evenly distributed on the outer side of the heat-conducting arc plate 3, and the bottom end of the mounting base 7 is fixedly connected to the outer side of the heat-conducting arc plate 3. The plug-in groove 8 is opened on the mounting base 7. The bottom end of the heat sink 5 is slidably inserted into the inside of the plug-in groove 8. The locking block 6 is symmetrically fixedly connected to the bottom ends of both sides of the heat sink 5. The locking plate 9 is fixedly installed at the opening end of the plug-in groove 8.

[0019] The protective device 2 includes a protective frame 10, with first protective rods 11 evenly distributed on both sides of the protective frame 10 and the first protective rods 11 fixedly connected to the side of the protective frame 10. Second protective rods 12 are evenly distributed on the top of the protective frame 10, and the two ends of the second protective rods 12 are fixedly connected to the inner ends of both sides of the protective frame 10.

[0020] The protective frame 10 is fixedly installed on the outside of the heat-conducting arc plate 3 by bolts. The heat sink 5 is isolated by the first protective rod 11 and the second protective rod 12 to prevent the heat sink 5 from damaging the internal circuits or other parts.

[0021] The heat sink 5 is made of diamond, while the heat-conducting arc plate 3 and the mounting base 7 are both made of copper. Copper has strong thermal conductivity and is easy to shape to fix the heat sink 5. Diamond has high thermal conductivity and excellent heat dissipation performance, thereby achieving rapid heat dissipation of the motor.

[0022] The mounting base 7 has a limiting hole at one end near the retaining plate 9, and the retaining plate 9 is fixedly connected to a limiting block that matches the limiting hole on the side near the mounting base 7. The heat sink 5 is fixed by mounting the retaining plate 9 on the mounting base 7.

[0023] Working principle: During use, the heat-conducting arc plate 3 is first installed on the outside of the motor through the locking block 6. Then, silicone is applied to the inside of the insertion slot 8, and the end of the heat sink 5 near the locking block 6 is slidably inserted into the inside of the insertion slot 8. Then, the locking plate 9 is inserted into the mounting base 7 by external force and fixed with bolts. Then, the protective frame 10 is fixed to the outside of the heat-conducting arc plate 3 with bolts. At this time, the installation is completed. When the motor starts, the heat generated by the motor is absorbed by the heat-conducting arc plate 3 and transferred to the mounting base 7. Then, the mounting base 7 transfers the heat to the inside of the heat sink 5. The heat sink 5 diffuses the heat to the outside. Since the heat sink 5 is made of diamond material, it has high thermal conductivity and excellent heat dissipation performance, thereby realizing rapid heat dissipation of the motor. The heat sink 5 is isolated by the protective frame 10, the first protective rod 11 and the second protective rod 12 to prevent the heat sink 5 from causing damage to external objects.
