[0002] The motor, commonly known as the motor, is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is mainly divided into DC motors and AC motors. Its main structure includes a stator and a rotor.

Moreover, the setting of the heat dissipation holes is also easy to enter dust, further affecting the use state and service life of the motor. Content of the Utility Model

[0008] Preferably, a plurality of heat-absorbing fins are fixedly installed at both outer ends of the heat-absorbing liquid pipe, and one end of each heat-absorbing fin penetrates and is inserted into the inside of the heat-absorbing liquid pipe.

[0009] Through the above technical solution, the heat-absorbing fins can enhance the contact area with the internal hot air flow, which is beneficial to the full absorption of heat by the liquid in the heat-absorbing liquid pipe, thereby reducing the internal temperature.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0029] Embodiment 1:

[0030] As Figures 1-4 shown, an energy-saving motor with high heat dissipation efficiency provided by the present utility model includes a motor housing 1. The left and right ends of the motor housing 1 are respectively fixedly connected with a front cover 2 and a rear cover 3 by bolts. A stator 5 is arranged on the inner side wall of the motor housing 1. A rotor 6 is rotatably installed inside the stator 5. A rotating shaft 7 is fixedly installed through the inside of the rotor 6. A continuously winding and sunken groove 8 is formed on the inner wall of the motor housing 1. A heat-absorbing liquid pipe 9 is fixedly installed in the sunken groove 8. A bottom plate 4 is arranged below the motor housing 1. Four support columns 21 are fixedly connected between the motor housing 1 and the bottom plate 4. A circulating pump 10 is fixedly installed on the upper right side of the bottom plate 4. A heat dissipation pipe 11 and a first connecting pipe 12 in a meandering spiral shape are respectively fixedly connected to the water inlet and the water outlet of the circulating pump 10. The ends of the heat dissipation pipe 11 and the first connecting pipe 12 far away from the circulating pump 10 are respectively fixedly connected to both ends of the heat-absorbing liquid pipe 9.

[0031] Specifically, a plurality of heat-absorbing fins 27 are fixedly installed at both outer ends of the heat-absorbing liquid pipe 9, and one end of each heat-absorbing fin 27 penetrates and is inserted into the inside of the heat-absorbing liquid pipe 9. The advantage is that the heat-absorbing fins 27 can enhance the contact area with the internal hot air flow, which is beneficial to the full absorption of heat by the liquid in the heat-absorbing liquid pipe 9, thereby reducing the internal temperature.

[0032] Specifically, a collar 13 is fixedly sleeved on the outer side of the right end of the rotating shaft 7, and a plurality of fan blades 14 are fixedly installed on the outer side of the collar 13. The advantage is that when the motor is working, the internal rotating shaft 7 rotates, driving the collar 13 and the fan blades 14 to rotate, accelerating the flow of the internal air flow, and thus quickly taking away the heat.

[0033] Embodiment 2:

[0034] As Figure 1 and Figure 2 shown, as an improvement to the previous embodiment. Specifically, a rotating column 15 is rotatably installed in the middle of the right side of the rear cover 3. A rotating cap 16 is fixedly installed at the right end of the rotating column 15, and a rotating disc 17 is fixedly sleeved on the outer side of the rotating column 15. The advantage is that rotating the rotating cap 16 drives the rotating column 15 to rotate, which can drive the rotating disc 17 to rotate.

[0035] Specifically, two first heat dissipation grooves 18 are symmetrically formed in the rear cover 3, and two second heat dissipation grooves 19 with the same area as the two first heat dissipation grooves 18 are symmetrically formed in the rotating disc 17. Dust-proof nets 20 are arranged in both the first heat dissipation grooves 18 and the second heat dissipation grooves 19. The advantage is that when the rotating disc 17 rotates, the overlapping area of the first heat dissipation grooves 18 and the second heat dissipation grooves 19 can be adjusted to control the ventilation efficiency and prevent excessive dust from entering. The dust-proof nets 20 further improve the dust-proof protection.

[0036] Specifically, a fixed box 22 is fixedly installed at the lower left end of the front cover 2, and a communication groove 23 communicating with the fixed box 22 is formed in the front cover 2. A second communication pipe 24 is fixedly connected to the lower side of the fixed box 22. The advantage is that the internally flowing heat flow flows into the fixed box 22 from the communication groove 23 and then is delivered into the second communication pipe 24.

[0037] Specifically, the lower end of the second communication pipe 24 is fixedly connected to an air outlet box 25. The opening of the air outlet box 25 faces the heat dissipation pipe 11, and a dust-proof net 26 is fixedly installed inside. The advantage is that the air flow in the second communication pipe 24 is ejected from the air outlet box 25, accelerating the air flow velocity around the heat dissipation pipe 11, thereby improving the efficiency of the heat dissipation pipe 11 in dissipating heat outward, reducing the temperature of the internal coolant, and facilitating the recycling of the coolant back into the heat absorption liquid pipe 9 for heat absorption use. The dust-proof net 26 prevents dust from entering.

[0038] During use, the motor working shaft 7 drives the ring sleeve 13 to rotate, and the fan blades 14 generate wind to blow the internal hot air flow from the right end to the left end of the sunken groove 8. At the same time, the circulation pump 10 pumps the coolant into the heat absorption liquid pipe 9, and the heat in the air is absorbed more quickly by contacting the surrounding hot air flow through each heat absorption fin 27. The coolant with an increased temperature is sent into the heat dissipation pipe 11, and the internally generated wind is sent into the fixed box 22 from the communication groove 23 and then sent into the air outlet box 25 by the second communication pipe 24 and ejected to the right, accelerating the air flow velocity around, thereby improving the rate of the coolant in the heat dissipation pipe 11 in outputting heat outward, reducing the temperature of the coolant, and finally being sent back to the heat absorption liquid pipe 9 by the circulation pump 10 for recycling. During the working process, according to the running intensity of the motor and the environment, the rotating cap 16 is rotated to drive the rotating column 15 to rotate, further driving the rotating disc 17 to rotate, and controlling and adjusting the overlapping area of the first heat dissipation grooves 18 and the second heat dissipation grooves 19 to maintain good heat dissipation efficiency.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
