Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology, and relates to a motor, and more particularly to a motor with high-efficiency heat dissipation. Background Technology
[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuit diagrams, an electric motor is represented by the letter M. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines.
[0003] When an electric motor is working, the internal resistance of its electronic components converts electrical energy into heat, causing heat to accumulate inside the motor and eventually leading to motor failure due to the increased temperature. Existing motors use fans for heat dissipation, but this is insufficient to meet the motor's cooling needs, so a more effective cooling method is required.
[0004] For example, the motor with good heat dissipation with application number 2017208693021 includes a motor housing, a junction box assembly, a heat sink, a rear end cover, a fan blade, and a fan cover. The junction box assembly is installed on the upper end of the motor housing, and the heat sink is provided on the side. The rear end cover is installed on the rear end face of the motor housing, and the fan blade is located behind the rear end cover. A first step surface is opened on the rear end of the junction box assembly. The fan cover has a shell structure, with the upper inner wall of the fan cover fitting against the first step surface and the lower end of the fan cover fitting against the rear end of the heat sink.
[0005] In order to solve the problem of gaps between the fan cover and the junction box, the above-mentioned patent sets a fitting surface on the junction box to fit with the fan cover, so as to prevent gaps from forming and causing wind energy loss, which in turn leads to poor air cooling effect. However, air cooling is not enough to meet the heat dissipation needs of the motor. Utility Model Content

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0021] like Figures 1 to 4 As shown, this utility model can be achieved through the following embodiments: A high-efficiency heat dissipation motor includes a motor body 1, which includes a stator 11, a rotor 12 and a shaft 13. A fan 131 is installed on the shaft 13. An end cover 2 is installed at the output end of the motor. A cooling cover 3 is connected to the end cover 2. An L-shaped plate 5 is installed inside the cooling cover 3. A cooling plate 4 is installed on the L-shaped plate 5. A filter screen is installed at the end of the cooling cover 3 away from the end cover 2. Heat dissipation holes 31 are opened between the L-shaped plates 5 in the motor body 1. A dust-blocking frame 32 is laid inside the heat dissipation holes 31.
[0022] An L-shaped plate 5 is installed on the outside of the motor body 1, and a cooling plate 4 is installed inside the L-shaped plate 5. This allows the user to easily remove the L-shaped plate 5 and replace the cooling plate 4. The water inlet and outlet on the cooling plate 4 are used to connect water pipes to facilitate the delivery of cold water to the cooling plate 4. A filter screen is used to filter impurities entering through the end cap 2, preventing dust from entering the motor body 1 and affecting the motor's heat dissipation. Heat dissipation holes 31 are provided between the L-shaped plates to increase the heat dissipation area of the motor. At the same time, the airflow guided by the fan 131 blows across the surface of the motor body 1 and flows out through the heat dissipation holes 31, improving the heat dissipation efficiency. A dust trap 32 is fixedly installed inside the heat dissipation holes 31 to intercept dust and prevent dust from accumulating on the outside of the motor body 1.
[0023] like Figure 1 and Figure 2 As shown, a ventilation section 41 is provided on the cooling plate 4. The ventilation section 41 is located behind the dustproof net, and a ventilation slot 411 is provided on the ventilation section 41. The ventilation section 41 is part of the cooling plate 4. The water inlet is installed at the end of the ventilation section 41, so that cooling water flows through the ventilation section 41. The ventilation slot 411 allows airflow to flow through the ventilation section 41 and be cooled by the ventilation section 41 before entering the motor body 1, thereby improving heat dissipation efficiency.
[0024] like Figure 1 and Figure 4 As shown, a rotating rod 51 is provided on the L-shaped plate 5, and the rotating rod 51 is installed inside the cooling cover 3. The L-shaped plate 5 can rotate with the rotating rod 51, so that the L-shaped plate 5 drives the cooling plate 4 to be exposed, which facilitates quick replacement of the cooling plate 4.
[0025] like Figure 1 and Figure 4As shown, the L-shaped plate 5 has a mounting groove 52, and the cooling plate 4 has a mounting part 42. The mounting groove 52 and the mounting part 42 are connected by countersunk bolts 6. After the L-shaped plate 5 is flipped over and exposed, the cooling plate 4 can be disassembled and replaced by turning the countersunk bolts 6.
[0026] like Figure 4 As shown, a protruding plate 53 extends from the L-shaped plate 5, and a sealing part 531 extends from the protruding plate 53. A sealing gasket 7 is installed on the cooling cover 3. The sealing part 531 extends from the protruding plate 53, so that the sealing part 531 and the sealing gasket 7 cooperate to prevent airflow carrying dust from flowing into the protruding plate 53 through the gap, thus ensuring stable heat dissipation of the cooling cover 3.
[0027] like Figures 1 to 3 As shown, an opening 33 is provided at the rear end of the cooling cover 3, and a filter screen 43 is installed at the rear end of the cooling cover 3. A slot 331 is provided on the opening 33, and a locking block 8 is installed next to the slot 331. A spring 81 is installed between the slot 331 and the locking block 8. A corresponding limiting block 54 is installed on the L-shaped plate 5. The filter screen 43 is designed to intercept dust that enters the cooling cover 3 with the airflow; the slot 331 is used to engage the limiting block 54, and the spring 81 pushes the locking block 8 into the limiting block 54 to achieve the connection between the L-shaped plate 5 and the cooling cover 3, preventing the L-shaped plate 5 from vibrating during motor operation and affecting the heat dissipation of the cooling plate 4.
[0028] like Figure 1 and Figure 2 As shown, an exchange section 44 is welded onto the cooling plate 4, and the exchange section 44 is made of copper. The exchange section 44 is the contact part between the cooling plate 4 and the motor body 1, and is used to realize the heat exchange between the motor body 1 and the cold water in the cooling plate 4. Copper has good thermal conductivity, which can improve heat dissipation efficiency.
[0029] The working principle of this utility model is as follows: The cooling cover 3 is installed outside the motor body 1. The L-shaped plate 5 is fixed to the cooling cover 3 by the rotating rod 51. The mounting part 42 on the cooling plate 4 is inserted into the mounting groove 52 of the L-shaped plate 5, and countersunk bolts 6 are inserted to fix the cooling plate 4 in the L-shaped plate 5. Then the L-shaped plate 5 is closed, so that the L-shaped plate 5 is inserted into the slot 331, and the locking block 8 in the slot 331 is locked into the L-shaped plate 5, realizing the installation and locking of the L-shaped plate 5 and the cooling cover 3. Then, water pipes are inserted into the water inlet and outlet of the cooling plate 4, and then the filter screen 2 43 is installed to complete the assembly. When replacing the cooling plate 4, slide the locking block 8 to disconnect the connection between the L-shaped plate 5 and the cooling cover 3, remove the filter screen 2 43, pull out the water pipe at the water inlet, flip the L-shaped plate 5, unscrew the countersunk bolts 6, and then remove and replace the cooling plate 4.
