Description

Technical Field

[0001] This utility model relates to the field of motors, and more specifically, to a motor suitable for high-temperature environments. Background Technology

[0002] With the continuous advancement of industrialization, applications in various high-temperature environments are becoming increasingly widespread, especially in heavy machinery, metallurgy, chemical industry, mining and other equipment operating under extreme temperatures. As a core power component, the motor faces severe high-temperature challenges, and the high-temperature environment has a significant impact on the long-term stability, operating efficiency and service life of the motor.

[0003] Existing motors typically use air-cooling systems for heat dissipation. However, air-cooling alone is limited by external ambient temperature, air circulation, and the effectiveness of heat dissipation, often making it difficult to maintain the motor's normal operating temperature in high-temperature environments. Some motors using water cooling simply have flow channels in the casing for coolant or water to pass through; after prolonged use, this can easily lead to casing corrosion and lacks sufficient heat conduction, resulting in poor heat dissipation efficiency. Therefore, a high-temperature environment-suitable motor is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the current limitations of air cooling in motors, which are restricted by external ambient temperature, air circulation, and heat dissipation effect, making it difficult to maintain the normal operating temperature of the motor in high-temperature environments. In contrast, some motors that use water cooling simply have flow channels on the outer casing for coolant or water to flow through, which can easily lead to rust on the outer casing after prolonged use and lacks sufficient heat conduction, resulting in poor heat dissipation efficiency.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The present invention is as follows: a high-temperature environment applicable motor, including a housing, a motor stator, a motor rotor and a shaft, wherein the motor stator, motor rotor and shaft are sequentially fitted inside the housing, a circulating heat dissipation mechanism for rapidly cooling the housing is provided on one side of the housing, and a heat-conducting component for absorbing and dissipating heat inside the housing is provided on one side of the housing.

[0007] The circulating heat dissipation mechanism includes a heat-conducting plate fixedly connected to the outer wall of the outer shell. A mounting frame is fixedly connected to the outer wall of the outer shell. A heat-conducting copper pipe is installed inside the mounting frame. An injection pipe and an exhaust pipe are respectively connected to the two ends of the heat-conducting copper pipe. A front cover and a rear cover are respectively bolted to the two openings on both sides of the outer shell. Graphite bearings are installed at both ends of the rotating shaft. Multiple fan blades are installed at the end of the rotating shaft near the rear cover. A protective cover is bolted to the side of the outer shell near the fan blades.

[0008] As a preferred technical solution of this utility model, the heat-conducting component includes multiple ventilation openings opened inside the rear end cover, and multiple heat-conducting rings are fixedly connected to the side of the rear end cover near the fan blade, the heat-conducting rings being made of aluminum alloy.

[0009] As a preferred technical solution of this utility model, a coil frame is fixedly connected to the top of the outer shell, a wire outlet tube is fixedly connected to one side of the coil frame, a wire hole is opened through the inside of the coil frame, and the coil frame communicates with the inside of the outer shell through the wire hole.

[0010] As a preferred technical solution of this utility model, the outer wall of the shell is fixedly connected to two fixing brackets, and one side of each of the two fixing brackets is fixedly connected to multiple reinforcing ribs, and the interior of each of the two fixing brackets has two threaded holes.

[0011] As a preferred technical solution of this utility model, a mounting ring is fixedly connected to the side of the protective cover away from the outer shell, and a dustproof net is bolted to the side of the mounting ring away from the protective cover.

[0012] As a preferred technical solution of this utility model, a sealing sleeve is snapped onto the side of the cable outlet tube away from the coil frame, and the sealing sleeve is made of rubber.

[0013] As a preferred technical solution of this utility model, the outer wall of the mounting frame is provided with a heat insulation layer, and the heat insulation layer is made of glass fiber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The circulating heat dissipation mechanism enables rapid absorption and dissipation of heat generated within the casing. When the motor stator, rotor, and shaft are operating normally, the generated heat accumulates inside the casing. The heat-conducting fins are in close contact with the outer wall of the casing, absorbing the heat within. The discharge pipe is connected to an external extraction device, and coolant is injected through the injection pipe. The coolant flows through a spiral heat-conducting copper tube, absorbing the heat on the heat-conducting fins for rapid cooling. Simultaneously, the rotation of the shaft drives the fan blades to rotate, blowing the heat out of the casing and reducing the impact of high-temperature environments on the motor stator, rotor, and shaft.

[0016] 2. The heat-conducting components enable rapid heat conduction inside the casing; multiple vents facilitate airflow from the fan within the casing, quickly guiding heat from the casing to the heat-conducting ring, which, in conjunction with the fan blades, accelerates heat flow.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1 and Figure 3 As shown, this embodiment proposes a high-temperature environment applicable motor, including a housing 1, a motor stator 2, a motor rotor 3 and a shaft 4. The motor stator 2, the motor rotor 3 and the shaft 4 are sequentially fitted inside the housing 1. A circulating heat dissipation mechanism 5 for rapidly cooling the housing 1 is provided on one side of the housing 1, and a heat conduction component 6 for absorbing and dissipating the heat inside the housing 1 is provided on one side of the housing 1.

[0028] like Figure 3 As shown, the circulating heat dissipation mechanism 5 includes a heat-conducting plate 501 fixedly connected to the outer wall of the outer shell 1. The heat-conducting plate 501 is cylindrical and wraps around the outer wall of the outer shell 1, allowing it to quickly absorb heat from the outer shell 1. A mounting frame 502 is fixedly connected to the outer wall of the outer shell 1. A heat-conducting copper pipe 503 is disposed inside the mounting frame 502. The heat-conducting copper pipe 503 is spirally wound around the outer wall of the heat-conducting plate 501. An injection pipe 504 and an outlet pipe 505 are respectively connected to both ends of the heat-conducting copper pipe 503. Both the injection pipe 504 and the outlet pipe 505 extend to the outside of the mounting frame 502, allowing external coolant to circulate in the spiral. In the heat-conducting copper tube 503, a front cover 506 and a rear cover 507 are respectively attached to the two openings on both sides of the outer shell 1. Graphite bearings 508 are provided at both ends of the rotating shaft 4. The outer rings of the two graphite bearings 508 are respectively fixedly connected to the inner walls of the front cover 506 and the rear cover 507. The graphite bearings 508 have high temperature resistance and self-lubrication, which can reduce the heat generated by the rotating shaft 4 when rotating. Multiple fan blades 509 are provided at the end of the rotating shaft 4 near the rear cover 507. A protective cover 510 is attached to the side of the outer shell 1 near the fan blades 509. The multiple fan blades 509 are all located inside the protective cover 510. The fan blades 509 and the protective cover 510 cooperate to provide air cooling. In use, external coolant is injected into the injection pipe 504 on the heat-conducting copper pipe 503, and then the external extraction device is connected to the discharge pipe 505 so that the coolant can flow in the spiral heat-conducting copper pipe 503. The heat-conducting plate 501 can absorb the heat generated in the outer shell 1 when the motor rotor 3 rotates, and dissipate the heat through the coolant flowing in the heat-conducting copper pipe 503. The graphite bearing 508 has the characteristics of high temperature resistance and self-lubrication, which can reduce the friction between the two ends of the shaft 4 and the front cover 506 and the rear cover 507, and avoid generating additional heat. The fan blade 509 will rotate synchronously with the rotation of the shaft 4, and cooperate with the protective cover 510 to provide additional air cooling.

[0029] like Figure 4As shown, the heat-conducting component 6 includes multiple vents 601 formed inside the rear cover 507. Multiple heat-conducting rings 602, made of aluminum alloy, are fixedly connected to the side of the rear cover 507 near the fan blade 509. When the fan blade 509 rotates, it blows the heat from the outer casing 1 out through the protective cover 510. The multiple vents 601 facilitate airflow within the outer casing 1, while the heat-conducting rings 602 quickly absorb heat. Together with the fan blade 509, they accelerate heat flow.

[0030] like Figure 4 As shown, a coil frame 7 is fixedly connected to the top of the outer casing 1, and a cable outlet pipe 8 is fixedly connected to one side of the coil frame 7. A wire hole 9 is provided through the inside of the coil frame 7, and the coil frame 7 communicates with the inside of the outer casing 1 through the wire hole 9. The coil frame 7, through the cable outlet pipe 8 and the wire hole 9, can provide isolation and protection for the wiring terminals of the motor stator 2 and the external cable.

[0031] like Figure 1 As shown, two fixing brackets 10 are fixedly connected to the outer wall of the outer casing 1. Multiple reinforcing ribs 11 are fixedly connected to one side of each fixing bracket 10. Two threaded holes 12 are opened inside each fixing bracket 10. The fixing brackets 10 and the threaded holes 12 are used together to make it easy to fix the outer casing 1 in a designated position, while the reinforcing ribs 11 can increase the strength of the fixing brackets 10.

[0032] like Figure 5 As shown, a mounting ring 13 is fixedly connected to the side of the protective cover 510 away from the outer shell 1, and a dustproof net 14 is bolted to the side of the mounting ring 13 away from the protective cover 510. The mounting ring 13 and the dustproof net 14 work together to intercept external dust and facilitate disassembly, cleaning and maintenance.

[0033] like Figure 4 As shown, a sealing sleeve 15 is snapped onto the side of the cable outlet tube 8 away from the cable reel 7. The sealing sleeve 15 is made of rubber. The sealing sleeve 15 can increase the sealing performance of the cable outlet tube 8 and prevent external dust from entering the cable reel 7 and affecting the wiring terminals.

[0034] like Figure 3 As shown, the outer wall of the mounting frame 502 is provided with a heat insulation layer, which is made of fiberglass. The fiberglass heat insulation layer can isolate external heat from affecting the heat-conducting copper pipe 503, allowing the coolant to better absorb the heat on the heat-conducting plate 501.

[0035] Specifically, when using this high-temperature environment applicable motor: place the outer casing 1 in the designated position using the mounting bracket 10, and then screw the external bolts into the threaded holes 12 to complete the fixing of the outer casing 1 (e.g., Figure 1(As shown); external coolant is injected into the injection pipe 504 on the heat-conducting copper pipe 503, and then the external extraction device is connected to the discharge pipe 505, so that the coolant can flow in the spiral heat-conducting copper pipe 503. The heat-conducting plate 501 can absorb the heat generated in the outer casing 1 due to the rotation of the motor rotor 3, and dissipate the heat through the coolant flowing in the heat-conducting copper pipe 503. The graphite bearing 508 has the characteristics of high temperature resistance and self-lubrication, which can reduce the friction between the two ends of the shaft 4 and the front cover 506 and the rear cover 507, and avoid generating additional heat (such as...). Figure 3 (As shown); the fan blades 509 rotate synchronously with the rotation of the shaft 4, blowing the heat in the outer casing 1 out through the protective cover 510. The multiple vents 601 facilitate airflow in the outer casing 1, while the heat-conducting ring 602 can quickly absorb heat. In conjunction with the fan blades 509, it can accelerate the flow of heat (as shown). Figure 4 (As shown); When wiring, one end of the motor stator 2 and one end of the external cable can be passed through the wire hole 9 and the outlet pipe 8 respectively, so that the wiring terminals of the motor stator 2 and the external cable are located in the cable reel 7, providing isolation and protection for the wiring terminals (e.g. Figure 4 (As shown).

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
