Description

Technical Field

[0001] The utility model relates to the field of industrial equipment, in particular to a motor with a heat dissipation function. Background Art

[0002] The electronic control board (ECB) plays a crucial role in the core structure of motor equipment. It's not only a collection of electronic components but also the hub for power conversion and signal processing. With the rapid advancement of electronic technology, the integration of ECBs has increased significantly. The various electronic components onboard, particularly the MOS transistors (metal oxide semiconductor field-effect transistors, hereinafter referred to as transistors), which serve as the core of power control, generate significant heat while performing high-performance computing and power conversion.

[0003] However, in current electronic control board designs, heat-generating components such as transistors are distributed in a dispersed layout. While this layout offers some flexibility in circuit design and optimization, it struggles to effectively dissipate heat. The dispersed transistors result in uneven heat distribution across the board's surface, making it difficult to form a continuous, efficient heat conduction path. This in turn exacerbates localized heat accumulation, reducing heat dissipation efficiency and potentially leading to serious consequences such as component overheating, performance degradation, and even damage, impacting normal equipment operation.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0028] like Figures 1 to 6As shown, a motor with a heat dissipation function includes a stator bracket 1, an end cover 2 mechanically connected to the stator bracket 1, an assembly cavity 4 provided in the end cover 2, an electric control board 3 provided in the assembly cavity 4, a transistor 5 provided at one end of the electric control board 3, a first heat dissipation plate 7 provided at one end of the stator bracket 1 and used to abut against the transistor 5, and a second heat dissipation plate 8 provided at one end of the end cover 2 and used to abut against the transistor 5; wherein one side of the first heat dissipation plate 7 abuts against one side surface of the transistor 5, and the second heat dissipation plate 8 abuts against the other side surface of the transistor 5; it is worth noting that The first heat sink 7 and the second heat sink 8 are detachably connected to the stator bracket 1 and the end cover 2, respectively. By arranging the transistor 5 at one end of the electronic control board 3 and covering the upper and lower surfaces of the transistor 5 with the first heat sink 7 and the second heat sink 8, respectively, the stator bracket 1 and the end cover 2 are locked together, squeezing the transistor 5 in the middle, so that the heat of the transistor 5 is absorbed by the first heat sink 7 and the second heat sink 8, and dissipated through the stator bracket 1 and the end cover 2, thereby preventing the heat on the transistor 5 from being transmitted to the electronic control board 3, thereby extending the service life of the electronic control board 3.

By providing the first abutment block 12 and the second abutment block 13, the transistor 5 is clamped between the first abutment block 12 and the second abutment block 13. Since the electronic control board 3 is mechanically connected to the transistor 5, the electronic control board 3 is suspended between the stator bracket 1 and the end cover 2, effectively preventing heat from the stator bracket 1 and the end cover 2 from being transferred to the electronic control board 3.

[0030] Furthermore, a third abutment block 15 with a third heat sink 6 is provided at one end of the assembly cavity 4 away from the second abutment block 13, and one end of the electronic control board 3 abuts against the third heat sink 6. By providing the third heat sink 6 and the third abutment block 15, one end of the electronic control board 3 is prevented from being too heavy and causing an unstable center of gravity, thereby further enhancing the assembly stability of the electronic control board 3 in the assembly cavity 4.

[0031] Furthermore, a capacitor assembly 16 is provided on one side of the electronic control board 3 close to the assembly cavity 4, and a gap is generated between the capacitor assembly 16 and the end cover 2 through the assembly cavity 4 to prevent heat from being transferred to the capacitor assembly 16; and further, a plurality of heat dissipation fins 17 are provided on the outer side of one end of the end cover 2 close to the second abutment block 13. By providing the heat dissipation fins 17, the heat dissipation performance of this embodiment is further enhanced, heat accumulation in the assembly cavity 4 is avoided, and the heat dissipation speed on the end cover 2 is accelerated.

[0032] The electric control board 3 is evenly provided with a plurality of openings 18, the end cover 2 is provided with a plurality of first screw holes 19 correspondingly connected to the openings 18, and the stator bracket 1 is provided with a plurality of second screw holes 20 correspondingly connected to the first screw holes 19; by providing the first screw holes 19 and the second screw holes 20, the user sequentially passes screws through the first screw holes 19, the openings 18, and the second screw holes 20, so that the electric control board 3 is fixed between the stator bracket 1 and the end cover 2, further strengthening the connection structure of the present embodiment, preventing the electric control board 3 from falling off in the present embodiment, and extending the service life of the present embodiment.

[0033] The stator bracket 1 is provided with a plurality of heat dissipation holes 14 . The heat dissipation effect of this embodiment is further enhanced by providing the heat dissipation holes 14 .

[0034] Working principle: The stator bracket 1 and the end cover 2 are locked together, squeezing the transistor 5 in the middle so that the heat of the transistor 5 is absorbed by the first heat sink 7 and the second heat sink 8, and dissipated through the stator bracket 1 and the end cover 2.
