According to the structure, it can be divided into asynchronous motors (low cost) and synchronous motors (high precision). Electric motors are widely used in industry (machine tools, pumps), transportation (electric vehicles), household appliances (fans, washing machines) and new energy fields (wind power generation). Their high efficiency and controllability contribute to the development of automation. The future trend is higher energy efficiency, intelligence and integration, making them a key power source for modern society.

[0018] This invention provides a motor structure that facilitates heat dissipation. Compared with the prior art, it has the following advantages:

[0019] Beneficial effects:

[0020] This heat-dissipating motor structure, through the base in the motor body, can be installed in a designated position and provides a stable foundation for the casing. Then, through the cooperation of the stator and rotor, the motor shaft can rotate at high speed. At the same time, the high-speed rotating motor shaft can synchronously drive the fan to rotate. Since multiple first ventilation holes are opened on one end face of the casing, when the fan rotates, it can exhaust the heat located inside the casing to the outside through the first ventilation holes, thereby reducing the heat inside the casing and preventing heat accumulation. Then, through the heat dissipation component, it can dissipate heat from the outer wall of the casing and is also connected to the circulation component. Therefore, through the circulation component, the heat conducted by the heat dissipation component can be diffused outward, further improving the heat dissipation effect of the heat dissipation component on the casing. At the same time, the rotating fan can blow air to cool the circulation component, thus forming a virtuous cycle to promote the cooling effect of the motor body. Attached Figure Description

[0027] 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.

[0028] Please see Figures 1-3 This utility model provides a technical solution: a motor structure that facilitates heat dissipation, including a motor body 1, the motor body 1 including a housing, a stator provided on the inner wall of the housing, a rotor provided in the inner cavity of the stator, a motor shaft 2 provided in the middle of the stator, and the two ends of the motor shaft 2 respectively passing through the two ends of the housing, a base 3 fixedly provided on the bottom surface of the housing, a plurality of first ventilation holes 4 opened on one end face of the housing, a fan 5 provided on one end of the motor shaft 2 and outside the first ventilation holes 4; a heat dissipation component 6 provided on the top of the outer wall of the housing, a circulation component 7 provided on the top surface of the base 3 and outside the fan 5, the liquid inlet end of the circulation component 7 being conductively connected to the liquid outlet end of the heat dissipation component 6, and the liquid outlet end of the circulation component 7 being conductively connected to the liquid inlet end of the heat dissipation component 6;

[0029] The base 3 in the motor body 1 can be installed in a designated position and provides a stable foundation for the casing. Then, through the cooperation of the stator and rotor, the motor shaft 2 can rotate at high speed. At the same time, the high-speed rotating motor shaft 2 can synchronously drive the fan 5 to rotate. Since multiple first ventilation holes 4 are opened on one end face of the casing, when the fan 5 rotates, the fan 5 can exhaust the heat located in the casing from the first ventilation holes 4 to the outside, thereby reducing the heat inside the casing and preventing heat accumulation inside the casing. Then, through the heat dissipation component 6, it can dissipate heat from the outer wall of the casing and is also connected to the circulation component 7. Therefore, through the circulation component 7, the heat conducted by the heat dissipation component 6 can be diffused outward, further improving the heat dissipation effect of the heat dissipation component 6 on the casing. At the same time, the rotating fan 5 can blow air to cool the circulation component 7, thus forming a virtuous cycle to promote the cooling effect of the motor body 1.

[0030] See Figure 2 , Figure 4 The heat dissipation assembly 6 includes an arc-shaped hollow plate 61 disposed on the top of the outer wall of the casing. The inner cavity of the arc-shaped hollow plate 61 is provided with a first coil and filled with coolant. An outlet pipe 62 and an inlet pipe 63 are respectively disposed on both sides of one end face of the arc-shaped hollow plate 61. The two ends of the outlet pipe 62 are respectively connected to the outlet end of the first coil and the inlet end of the circulation assembly 7. The two ends of the inlet pipe 63 are respectively connected to the inlet end of the first coil and the outlet end of the circulation assembly 7. A liquid injection screw hole 65 is opened on one side of the outer wall of the arc-shaped hollow plate 61. A sealing screw 66 is rotatably connected to the inner cavity of the liquid injection screw hole 65. Multiple heat dissipation fins 64 are disposed on the outer wall of the arc-shaped hollow plate 61, and the multiple heat dissipation fins 64 are distributed in a linear array.

[0031] The arc-shaped hollow plate 61 in the heat dissipation assembly 6 can be installed on the outer wall of the housing and also for the installation of the first coil. The first coil can be connected to the circulation assembly 7 via the liquid outlet pipe 62 and the liquid inlet pipe 63. Through the sealing screw 66 in the liquid injection screw hole 65, the operator can easily inject coolant into the inner cavity of the arc-shaped hollow plate 61, thereby enabling the coolant to transfer heat better. The circulation assembly 7 can provide circulating liquid to the first coil, thereby removing the temperature of the coolant in the arc-shaped hollow plate 61, thus achieving the purpose of cooling the coolant. Through the multiple heat dissipation fins 64 located on the outer wall of the arc-shaped hollow plate 61 and distributed in a linear array, the arc-shaped hollow plate 61 and the coolant can be further cooled, thereby accelerating the cooling speed of the housing and improving the heat dissipation efficiency of the motor body 1.

[0032] See Figure 2 , Figure 4 and Figure 5 The circulation assembly 7 includes a micro circulation pump 71 disposed on one side of the top surface of the base 3. The inlet end of the micro circulation pump 71 is connected to the outlet end of the outlet pipe 62. The outlet end of the micro circulation pump 71 is connected to a second coil 72. The outlet end of the second coil 72 is connected to the inlet end of the inlet pipe 63. Multiple card holders 73 are disposed on the second coil 72. A stabilizing bracket 74 for mounting the multiple card holders 73 is disposed on the top surface of the base 3 and located on the micro circulation pump 71.

[0033] The micro-circulation pump 71 in the circulation assembly 7 can be installed on one side of the top surface of the base 3, and its inlet end can be connected to the outlet end of the outlet pipe 62. At the same time, its outlet end can also be connected to the second coil 72. Therefore, by turning on the micro-circulation pump 71, the liquid in the first coil can be drawn out by the outlet pipe 62 and transported to the second coil 72. Then the liquid flows in the second coil 72. At this time, the high-speed rotating fan 5 can blow air on the second coil 72, thereby rapidly cooling the second coil 72 and the liquid flowing in the second coil 72, and thus removing the heat from the liquid. Finally, the cooled liquid flows back to the first coil through the outlet end of the second coil 72 and the inlet pipe 63, thus circulating and achieving the purpose of cooling the coolant in the arc-shaped hollow plate 61. The bracket 73 and the stabilizing bracket 74 provide a stable foundation for the second coil 72, thereby improving the stability of the second coil 72 in use.

[0034] See Figure 2 , Figure 3A shield 8 is provided on the top surface of the base 3 and outside the circulation component 7. The outer wall of the shield 8 has multiple second ventilation holes 9. A fixing plate 10 is provided on one end face of the housing. The outer wall of the fixing plate 10 has an internal thread groove 11. The outer wall of the shield 8 has a stepped hole 12. The inner cavity of the stepped hole 12 is inserted with a positioning screw 13. The bottom end of the positioning screw 13 is rotatably connected to the inner cavity of the internal thread groove 11. Multiple fixing plates 10 and stepped holes 12 are provided, and each fixing plate 10 corresponds to each stepped hole 12.

[0035] By inserting the positioning screw 13 into the inner cavity of the stepped hole 12 and rotating it into the internal threaded groove 11 located on the fixing plate 10, the shield 8 can be fixed to one end face of the housing, thereby improving the stability of the shield 8. At the same time, the shield 8 can also provide protection for the fan 5 and the circulation assembly 7. Then, through multiple second ventilation holes 9, the fan 5 can easily blow heat away to a distance, thereby preventing heat from accumulating in the inner cavity of the shield 8.

[0036] During operation, the base 3 in the motor body 1 can be installed in a designated position and provides a stable foundation for the casing. Then, through the cooperation of the stator and rotor, the motor shaft 2 can rotate at high speed. At the same time, the high-speed rotating motor shaft 2 can synchronously drive the fan 5 to rotate. Since multiple first ventilation holes 4 are opened on one end face of the casing, when the fan 5 rotates, the fan 5 can exhaust the heat located inside the casing from the first ventilation holes 4 to the outside, thereby reducing the heat inside the casing and preventing heat accumulation inside the casing. Then, through the heat dissipation component 6, heat can be dissipated from the outer wall of the casing and it can also be connected to the circulation component 7. Therefore, through the circulation component 7, the heat conducted by the heat dissipation component 6 can be diffused outward, further improving the heat dissipation effect of the heat dissipation component 6 on the casing. At the same time, the rotating fan 5 can blow air to cool the circulation component 7, thus forming a virtuous cycle to promote the cooling effect of the motor body 1.

[0037] The arc-shaped hollow plate 61 in the heat dissipation assembly 6 can be installed on the outer wall of the housing and also for the installation of the first coil. The first coil can be connected to the circulation assembly 7 via the liquid outlet pipe 62 and the liquid inlet pipe 63. Through the sealing screw 66 in the liquid injection screw hole 65, the operator can easily inject coolant into the inner cavity of the arc-shaped hollow plate 61, thereby enabling the coolant to transfer heat better. The circulation assembly 7 can provide circulating liquid to the first coil, thereby removing the temperature of the coolant in the arc-shaped hollow plate 61, thus achieving the purpose of cooling the coolant. Through the multiple heat dissipation fins 64 located on the outer wall of the arc-shaped hollow plate 61 and distributed in a linear array, the arc-shaped hollow plate 61 and the coolant can be further cooled, thereby accelerating the cooling speed of the housing and improving the heat dissipation efficiency of the motor body 1.

[0038] The micro-circulation pump 71 in the circulation assembly 7 can be installed on one side of the top surface of the base 3, and its inlet end can be connected to the outlet end of the outlet pipe 62. At the same time, its outlet end can also be connected to the second coil 72. Therefore, by turning on the micro-circulation pump 71, the liquid in the first coil can be drawn out by the outlet pipe 62 and transported to the second coil 72. Then the liquid flows in the second coil 72. At this time, the high-speed rotating fan 5 can blow air on the second coil 72, thereby rapidly cooling the second coil 72 and the liquid flowing in the second coil 72, and thus removing the heat from the liquid. Finally, the cooled liquid flows back to the first coil through the outlet end of the second coil 72 and the inlet pipe 63, thus circulating and achieving the purpose of cooling the coolant in the arc-shaped hollow plate 61. The bracket 73 and the stabilizing bracket 74 provide a stable foundation for the second coil 72, thereby improving the stability of the second coil 72 in use.

[0039] By inserting the positioning screw 13 into the inner cavity of the stepped hole 12 and rotating it into the internal threaded groove 11 located on the fixing plate 10, the shield 8 can be fixed to one end face of the housing, thereby improving the stability of the shield 8. At the same time, the shield 8 can also provide protection for the fan 5 and the circulation assembly 7. Then, through multiple second ventilation holes 9, the fan 5 can easily blow heat away to a distance, thereby preventing heat from accumulating in the inner cavity of the shield 8.

[0040] In summary, this device, through the heat dissipation component 6, the circulation component 7, and the cooperating rotating fan 5, can reduce the heat inside the casing, thereby preventing heat accumulation inside the casing and improving the service life and safety of the motor body 1.
