Description

Technical Field

[0001] The present invention relates to the technical field of high-speed motors, and particularly to a heat exchange and cooling type high-speed motor. Background Art

[0002] A high-speed motor refers to a motor that has characteristics such as high power density, high transmission efficiency, low noise, and fast dynamic response compared to ordinary motors. The volume of a high-speed motor is much smaller than that of an ordinary motor with the same power. Connected to a prime mover, the traditional speed reduction mechanism is eliminated, and the moment of inertia is small. The high-speed motor used during operation can improve production efficiency and meet the requirements of modern industry for efficient and energy-saving equipment, driving the equipment to rotate rapidly, thereby improving the overall production efficiency. The invention with the publication number CN210669719U discloses a fast-cooling explosion-proof high-speed motor, which is provided with a first cooling pipe with coolant flowing through it. The first cooling pipe wraps the heat sinks on the high-speed motor inside it, and can fully take away the heat dissipated by the heat sinks at various positions, improving the cooling effect of the housing, thereby quickly and effectively cooling the high-speed motor.

[0003] The invention with the publication number CN112968566B discloses a shock-absorbing and cooling device for a motor pump. The drive shaft of the motor pump penetrates the heat dissipation housing horizontally, and the bottom of the motor pump is fixedly connected to the heat dissipation housing. The heat dissipation housing has a cavity for dissipating the heat of the motor pump. A seat body is provided below the heat dissipation housing, and the seat body is provided with a buffer mechanism for shock-absorbing and buffering the heat dissipation housing. The present invention has the following advantages: it can not only quickly dissipate heat and cool down, but also avoid the shock-absorbing effect of the motor pump, ensuring the service life of the motor pump.

[0004] However, the above high-speed motors with heat dissipation and cooling still have the following problems in actual use: Cooling is achieved by setting a recyclable heat dissipation pipeline outside the motor housing, but such a heat dissipation pipeline has a special-shaped structure and cannot be effectively attached to the motor housing, so its heat exchange efficiency cannot be improved during the cooling cycle. At the same time, the cooling components wrapped outside the motor often affect the heat exchange effect of the fan fins on the motor housing itself, thereby indirectly causing a decrease in heat exchange and cooling.

[0005] Therefore, a heat exchange and cooling type high-speed motor is proposed to solve the problems mentioned above. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-9 , the present invention provides the following technical solutions: Embodiment 1: To solve the problems existing in the existing high-speed motors during use, the following technical solutions are disclosed in this embodiment. A heat exchange and cooling type high-speed motor includes a motor body 1, and a protective housing 2, a front end cover 3, and a rear end cover 4 that make up the motor body 1. An output rotating shaft 5 is rotatably provided at the central position inside the protective housing 2; heat dissipation mechanisms are provided on both the upper and lower sides of the outside of the protective housing 2, and the heat dissipation mechanisms include external fan fins 6, and the external fan fins 6 are arranged horizontally at equal distances; the external fan fins 6 included in the heat dissipation mechanisms are fixedly installed on both the upper and lower sides of the outside of the protective housing 2, and the heat dissipation mechanisms include internal fan fins 9, and the internal fan fins 9 are provided on both the front and rear sides inside the protective housing 2.

[0026] Heat dissipation slots 10 are opened on both the front and rear sides inside the protective housing 2, and the heat dissipation slots 10 are used to install the equally spaced internal fan fins 9, and the symmetrically distributed internal fan fins 9 are used to absorb and conduct the heat inside the protective housing 2; the heat dissipation mechanisms include conduction brackets 11, and the inner ends of the conduction brackets 11 are fixedly connected to the right ends of the internal fan fins 9 on both the front and rear sides, and the outer ends of the symmetrically arranged conduction brackets 11 are connected through to the inside of a heat exchange water tank 7 included in the heat exchange mechanism.

[0027] As Figures 3-5 shown, the motor body 1 is composed of the protective housing 2, the front end cover 3, and the rear end cover 4. After being powered on, the electromagnetic conversion generates the rotation of the output rotating shaft 5, thereby driving the connected equipment to work. At the same time, during the operation of the motor body 1, the relatively sealed motor body 1 and the internal components generate heat and conduct it to the cavity of the protective housing 2. The heat dissipation slots 10 opened on the front and rear sides inside the protective housing 2 conduct the heat to the internal fan fins 9, and the conduction brackets 11 connected to the internal fan fins 9 transport the heat to the heat exchange water tank 7, so as to achieve heat dissipation through the refrigerant in the heat exchange water tank 7 and prevent excessive heat generation inside the protective housing 2 from affecting the work.

[0028] Furthermore, the protective housing 2 continuously dissipates heat outward. The external fan fins 6 arranged at equal distances on the upper and lower sides of its exterior absorb the heat. Since the external fan fins 6 are directly exposed to the outside air, the conducted heat is then dissipated outward into the air for exchange, reducing the pressure on the heat exchange mechanism and continuously performing heat dissipation work, thereby enhancing the efficiency of heat dissipation and temperature reduction.

[0029] Embodiment 2: To solve the problems existing in the use of existing high-speed motors, the following technical solutions are disclosed in this embodiment. Heat exchange mechanisms are provided on both the front and rear sides of the exterior of the protective housing 2. The heat exchange mechanism includes a heat exchange water tank 7, and heat exchange frames 8 are fixedly arranged on both the left and right sides of the exterior of the heat exchange water tank 7; the heat exchange mechanism includes a heat exchange circulation pipe 18, and the heat exchange circulation pipe 18 is fixedly installed on the upper and lower sides of the exterior of the protective housing 2. Moreover, the heat exchange circulation pipe 18 is distributed in an "S" shape structure among the equally spaced external fan fins 6, and the heat exchange circulation pipe 18 surrounds the equally spaced external fan fins 6.

[0030] The end of the heat exchange circulation pipe 18 included in the heat exchange mechanism is connected in a penetrating manner to the interior of the heat exchange water tank 7. The heat exchange water tank 7 is used to pump the refrigerant into the heat exchange circulation pipe 18, and the heat of the external fan fins 6 is assisted in being reduced through the distribution shape of the heat exchange circulation pipe 18; the heat exchange mechanism includes a heat exhaust fan assembly 19, and the heat exhaust fan assembly 19 is installed inside the symmetrically arranged heat exchange frames 8. The heat exchange frames 8 and the heat exhaust fan assembly 19 assist in dissipating heat and cooling the heat exchange water tank 7 that is mutually attached.

[0031] As Figure 3 、 Figures 5-6 shown, during the process of the motor body 1 dissipating heat and cooling through the external fan fins 6, the heat is conducted into the equally spaced external fan fins 6. Then, the heat exchange water tank 7 pumps the refrigerating liquid into the penetratingly connected heat exchange circulation pipe 18. Then, the heat exchange circulation pipe 18 arranged in an "S" - type structure surrounds the external fan fins 6, and then penetrates between the external fan fins 6. Then, it assists in absorbing and conducting the heat of the external fan fins 6 and re - circulating it into the interior of the heat exchange water tank 7 for exchange, thereby assisting in enhancing the heat dissipation efficiency of the heat dissipation mechanism.

[0032] Furthermore, the heat exchange frames 8 fixedly installed on both sides of the front of the heat exchange water tank 7 operate, and the heat exhaust fan assembly 19 installed inside them rotates, so as to discharge the heat of the refrigerant performing heat exchange inside the heat exchange water tank 7 to the outside in a negative - pressure manner, avoiding difficult rapid cooling due to long - term heat exchange.

[0033] Embodiment 3: To solve the problems existing in the existing high-speed motors during use, the following technical solutions are disclosed in this embodiment. A dust removal mechanism is provided at the right end of the protective housing 2, and the dust removal mechanism includes an incomplete gear 12, and the incomplete gear 12 is fixedly connected to the right end of the output rotating shaft 5 inside the protective housing 2. Moreover, both the upper and lower ends on the right side inside the protective housing 2 are rotatably provided with guide gears 13 through torsion springs; the dust removal mechanism includes a dust removal brush plate 14, and the dust removal brush plate 14 is slidably attached to the external fan fins 6 on both the upper and lower sides outside the protective housing 2. Moreover, guide brackets 15 are fixedly provided on both the upper and lower sides outside the protective housing 2, and guide slide rods 16 are fixedly provided inside the guide brackets 15.

[0034] The guide slide rod 16 included in the dust removal mechanism is elastically penetrated through the inside of the dust removal brush plate 14, and the right side of the dust removal brush plate 14 is fixedly connected to the left end of the traction steel cable 17. Moreover, the right end of the traction steel cable 17 is wound and connected to the rotating shaft of the guide gear 13, and the symmetrically distributed guide gears 13 and the incomplete gear 12 are meshed with each other.

[0035] As Figure 3 、 Figures 8-9 shown, when the output rotating shaft 5 of the motor body 1 rotates, it drives the fixedly connected incomplete gear 12 to rotate. During the process of meshing with the guide gear 13, it drives the traction steel cable 17 to be wound up. Then, the traction steel cable 17 drives the fixedly connected dust removal brush plate 14 to move to the right along the direction of the guide slide rod 16, so that the dust removal brush plate 14 can assist in dust removal for the attached external fan fins 6 and the heat exchange circulation pipe 18, and avoid the adhesion of powder debris from affecting the heat dissipation and cooling effect of the motor body 1.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
