Description

Technical Field

[0001] The present application relates to the technical field of stator cores, and in particular to a motor stator core structure and a corrosion-resistant surface coating with an integrated cooling system. Background Art

[0002] The motor stator is an important part of motors such as generators and starters. The stator is an important part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field and then generate (output) current.

[0003] Although the existing technology can improve the heat dissipation capacity of the external winding of the stator core, it only performs auxiliary heat dissipation through a number of auxiliary heat dissipation slots, and the temperature of the stator core is relatively high after the motor runs for a long time.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are defects in that it is difficult to quickly dissipate heat through the heat dissipation auxiliary slots, which leads to rapid temperature rise of the stator core and a lack of protective coating on the stator surface. Summary of the invention

[0005] In order to improve the problem of rapid temperature rise of the stator core when the motor is running, the present application provides a motor stator core structure and a corrosion-resistant surface coating with an integrated cooling system.

[0006] The motor stator core structure and corrosion-resistant surface coating of the integrated cooling system provided in this application adopt the following technical solutions:

[0007] In a first aspect, a motor stator core structure of an integrated cooling system includes a stator core body, wherein the stator core body includes a stator core body, a water cooling mechanism and a heat dissipation mechanism as a whole, and the stator core body is arranged inside a motor housing.

[0008] By adopting the above technical solution, the water cooling mechanism and the heat dissipation mechanism are integrated into the stator core body to form a compact cooling system, which solves the problems of poor heat dissipation effect and easy damage due to overheating of the traditional motor stator. The water cooling mechanism quickly takes away the heat of the stator core during operation through the flow of circulating coolant, reduces the stator temperature, and prevents damage to the core caused by overheating. The heat dissipation mechanism is combined with the structure of the stator core to increase the heat exchange area and optimize the heat dissipation path, so that the heat can be effectively diffused in the air, further improving the cooling efficiency.

[0009] The water cooling mechanism is used to cool the stator core body. The water cooling mechanism includes a heat-conducting metal ring fixedly mounted on the outer ring surface of the stator core body. An annular cooling cavity is provided inside the heat-conducting metal ring, and cooling water is poured into the annular cooling cavity. The water cooling mechanism also includes a water cooler arranged on the outer surface of the motor housing, and a circulating pump arranged on the outer surface of the water cooler.

[0010] By adopting the above technical solution, the water cooling mechanism transfers heat from the stator core body to the cooling water through the heat-conducting metal ring, and performs heat exchange through the cooling water in the annular cooling cavity, thereby effectively reducing the temperature of the stator core. The flow of cooling water in the annular cooling cavity can absorb heat evenly and avoid local overheating. The configuration of the water cooler and the circulating pump further optimizes the performance of the cooling system. The water cooler takes away the heat in the cooling water through the flow of external air, and the circulating pump ensures that the cooling water continues to flow to maintain an efficient heat exchange process.

[0011] Preferably, the heat dissipation mechanism accelerates the flow rate of air inside the motor housing.

[0014] By adopting the above technical solution and providing the metal heat-conducting plate and the heat-dissipating grooves, the heat exchange area between the heat-conducting metal ring and the stator core body is effectively increased, thereby improving the heat exchange efficiency.

[0015] Preferably, a water return cavity communicating with the annular cooling cavity is provided inside the metal heat conducting plate, and a guide plate extending into the water return cavity is fixedly provided on the inner wall of the annular cooling cavity.

[0016] By adopting the above technical solution and providing a water return chamber and a guide plate, cooling water can enter the water return chamber during the flow of cooling water, thereby further improving the adequacy of heat exchange.

[0017] Preferably, the liquid inlet end of the circulation pump is connected to the liquid outlet end of the water cooler, and the liquid outlet end of the circulation pump is provided with a water inlet hose for injecting cooled water into the annular cooling cavity, and the liquid inlet end of the water cooler is provided with a reflux hose extending to the inside of the annular cooling cavity.

[0018] By adopting the above technical solution and providing a reflux hose, the cooling water after heat exchange can be returned to the water cooler for circulation and cooling.

[0019] Preferably, the model of the water cooler is ZGLY-112ALC.

[0020] Preferably, the heat dissipation mechanism includes a fixed cylinder arranged at the end of the water inlet hose, and the fixed cylinder is installed on the outer surface of the heat-conducting metal ring, the end of the water inlet hose extends to the interior of the fixed cylinder, and the inner wall of the fixed cylinder is provided with a water inlet pipe extending to the interior of the annular cooling cavity.

[0021] By adopting the above technical solution and arranging a water inlet pipe, the water entering the fixed cylinder can enter the interior of the annular cooling cavity.

[0022] Preferably, a connecting pipe is fixedly provided at the end of the fixed cylinder, and a rotating shaft extending to the inside of the connecting pipe is rotatably provided on the inner wall of the fixed cylinder, an impeller is fixedly provided on the outer surface of the rotating shaft located inside the fixed cylinder, and a blowing fan blade is fixedly provided on the outer surface of the rotating shaft located inside the connecting pipe.

[0024] Preferably, a protective net is provided on the inner annular surface of the end of the connecting pipe, and four air inlets are provided on the outer annular surface of the connecting pipe close to the fixing tube in a circular array.

[0025] By adopting the above technical solution and providing an air inlet, air can easily enter the interior of the connecting pipe.

[0026] In a second aspect, the corrosion-resistant surface coating is formed by a physical vapor deposition method.

[0027] By adopting the above technical scheme and forming a corrosion-resistant surface coating by the physical vapor deposition (PVD) method, the corrosion resistance of the substrate surface can be effectively improved, and a uniform and dense coating can be deposited on the surface of metals, ceramics, plastics and other materials. The coating has excellent corrosion resistance and can effectively isolate the substrate from the corrosion of corrosive substances such as acids, alkalis and salts in the external environment. Through evaporation or sputtering in a vacuum environment, the coating molecules are accurately deposited in the form of atoms or molecules to form a high-adhesion film, which enhances the sealing and wear resistance of the coating, thereby extending the service life of the substrate.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] An embodiment of the present application discloses a motor stator core structure with an integrated cooling system.

[0039] Example 1

[0040] Reference Figures 1 to 5The stator core structure of the motor with an integrated cooling system includes a stator core body 900, which includes a stator core body 100, a water cooling mechanism 200 and a heat dissipation mechanism 300. The stator core body 100 is arranged inside the motor housing. The stator core body 900 effectively integrates the stator core body 100, the water cooling mechanism 200 and the heat dissipation mechanism 300 to form a compact and efficient cooling system. The stator core body 100 is arranged inside the motor housing, which can make full use of the motor housing space and improve the compactness and stability of the overall structure. The water cooling mechanism 200 realizes effective cooling of the stator core through the flow of cooling water, avoiding the uneven heat dissipation problem of traditional cooling methods. The heat dissipation mechanism 300 further improves the heat dissipation efficiency inside the motor housing by accelerating the air flow rate, ensuring that the motor can maintain a low temperature when running at high load to prevent performance loss caused by overheating.

[0041] Reference Figure 1 , Figure 2 The water cooling mechanism 200 cools the stator core body 100. The water cooling mechanism 200 includes a heat-conducting metal ring 201 fixedly mounted on the outer ring surface of the stator core body 100. An annular cooling cavity 202 is provided inside the heat-conducting metal ring 201, and cooling water is poured into the annular cooling cavity 202. The water cooling mechanism 200 also includes a water cooler 203 arranged on the outer surface of the motor housing. The model of the water cooler 203 is ZGLY-112ALC, and a circulating pump 204 arranged on the outer surface of the water cooler 203. The heat-conducting metal ring 201 is fixedly mounted on the outer ring surface of the stator core body 100, and the excellent thermal conductivity of the metal is used to quickly conduct heat. To the annular cooling cavity 202, the cooling water flows through the annular cooling cavity 202, taking away the heat of the stator core body. The water cooler of the water cooling mechanism 200 uses the external air flow to take away the heat in the cooling water, further enhancing the heat exchange effect. Combined with the circulating pump 204 on the outer surface, it can ensure the circulation of cooling water between the annular cooling cavity 202 and the water cooler 203, continuously and efficiently transfer and dissipate heat, so that the motor can effectively avoid overheating when running at high load for a long time, maintain the stability of the internal temperature of the motor, improve the working efficiency, reliability and service life of the motor, and solve the problems of uneven heat dissipation and low efficiency of traditional heat dissipation methods.

[0042] Reference Figure 1 and Figure 4The inner ring surface of the heat-conducting metal ring 201 is fixed with a plurality of metal heat-conducting plates 205 in a circular array, and the outer ring surface of the stator core body 100 is provided with a plurality of heat-dissipating grooves 206 adapted to the plurality of metal heat-conducting plates 205. By providing the metal heat-conducting plates 205 and the heat-dissipating grooves 206, the heat exchange area between the heat-conducting metal ring 201 and the stator core body 100 is effectively increased, thereby improving the heat exchange efficiency.

[0043] Reference Figure 1 and Figure 3 A return water chamber 207 connected to the annular cooling chamber 202 is provided inside the metal heat conducting plate 205, and a guide plate 208 extending into the return water chamber 207 is fixedly provided on the inner wall of the annular cooling chamber 202. By providing the return water chamber 207 and the guide plate 208, the cooling water can enter the return water chamber 207 during the flow, thereby further improving the adequacy of heat exchange.

The liquid inlet end of the water cooler 203 is provided with a reflux hose 2010 extending to the inside of the annular cooling cavity 202. By providing the reflux hose 2010, the cooling water after heat exchange can be refluxed into the water cooler 203 for circulation and cooling.

[0045] In this embodiment, by providing a water cooling mechanism 200, the motor stator core structure can, during actual use, enable the cooling water in the annular cooling cavity 202 to quickly exchange heat with the stator core body 100, and flow back to the water cooler 203 through the return hose 2010 for recooling and then circulation, thereby achieving the purpose of quickly cooling the stator core body 100.

[0046] Example 2

[0047] On the basis of Embodiment 1, the motor stator core structure of the integrated cooling system further includes a heat dissipation mechanism 300, referring to Figure 1 , Figure 3 , Figure 4 , Figure 5The heat dissipation mechanism 300 is used to speed up the flow rate of the air inside the motor housing. The heat dissipation mechanism 300 includes a fixed cylinder 301 arranged at the end of the water inlet hose 209, and the fixed cylinder 301 is installed on the outer surface of the heat-conducting metal ring 201. The end of the water inlet hose 209 extends to the inside of the fixed cylinder 301. The inner wall of the fixed cylinder 301 is provided with a water inlet pipe 302 extending to the inside of the annular cooling cavity 202. By providing the water inlet pipe 302, it is convenient for the water entering the fixed cylinder 301 to enter the inside of the annular cooling cavity 202. The heat dissipation mechanism 300 speeds up the flow rate of the air inside the motor housing, thereby improving the heat dissipation effect. The fixed cylinder 301 is arranged at the end of the water inlet hose 209. The heat dissipation mechanism 300 is arranged on the outer surface of the heat-conducting metal ring 201, ensuring that the cooling water can flow smoothly into the annular cooling cavity 202. The cooling water entering the fixed cylinder 301 can be guided to the inside of the annular cooling cavity 202 through the water inlet pipe 302, thereby realizing efficient transportation of cooling water, optimizing the distribution path of the water flow, and ensuring that the cooling water evenly covers the key parts of the stator core body 100, further improving the cooling efficiency. By accelerating the air flow rate and optimizing the flow of cooling water, the heat dissipation mechanism 300 effectively avoids the problem of motor overheating and maintains the temperature of the stator core stable. Under high load or long-term operation, the motor can maintain excellent working performance and a long service life.

[0048] Reference Figure 4 A connecting pipe 303 is fixedly provided at the end of the fixed cylinder 301, and a rotating shaft 304 extending to the inside of the connecting pipe 303 is rotatably provided on the inner wall of the fixed cylinder 301. An impeller 305 is fixedly provided on the outer surface of the rotating shaft 304 located inside the fixed cylinder 301. A blowing fan blade 306 is fixedly provided on the outer surface of the rotating shaft 304 located inside the connecting pipe 303. By arranging the impeller 305 and the blowing fan blade 306, the blowing fan blade 306 can be driven to rotate by the rotation of the impeller 305.

[0049] A protective net 307 is provided on the inner ring surface of the end of the connecting pipe 303 , and four air inlets 308 are provided in a circular array on the outer ring surface of the connecting pipe 303 close to the fixing tube 301 . The air inlets 308 facilitate air to enter the interior of the connecting pipe 303 .

[0050] In this embodiment, by setting up the heat dissipation mechanism 300, under the action of the circulating pump 204, the water in the water cooler 203 is transported to the inside of the annular cooling chamber 202 through the water inlet hose 209, so that the fan blades 306 can effectively accelerate the air inside the motor housing, thereby making the air flow faster, further improving the heat dissipation effect of the motor.

[0051] The working principle of the motor stator core structure of the integrated cooling system of the embodiment of the present application: during actual use, the motor stator core structure can transport the water cooled inside the water cooler 203 through the water inlet hose 209 to the annular cooling cavity 202 in the heat-conducting metal ring 201 through the circulating pump 204, so that the cooling water in the annular cooling cavity 202 can quickly exchange heat with the stator core body 100, and then flow back to the water cooler 203 through the return hose 2010 for re-cooling and then circulation, thereby achieving the purpose of quickly cooling the stator core body 100. Moreover, in the process of the water in the water cooler 203 being transported to the inside of the annular cooling chamber 202 through the water inlet hose 209 under the action of the circulating pump 204, the water flow can enter the fixed cylinder 301. When the water flow flows in the fixed cylinder 301, it can drive the impeller 305 to rotate. The rotation of the impeller 305 drives the rotating shaft 304 to rotate. The rotation of the rotating shaft 304 drives the blowing fan blades 306 in the connecting pipe 303 to rotate, so that the blowing fan blades 306 can effectively accelerate the air inside the motor casing, thereby making the air flow faster, further improving the heat dissipation effect of the motor.

[0052] The corrosion-resistant surface coating is formed by physical vapor deposition, which is achieved by evaporation deposition, magnetron sputtering and ion plating. Evaporation deposition uses resistance heating, electron beam heating or laser ablation to evaporate solid materials. Magnetron sputtering uses a combination of magnetic field and electric field to separate the sputtering source material from the target material and deposit it on the substrate. Ion plating uses an ion source to pre-treat the surface of the substrate to improve the adhesion and quality of the film, so that a corrosion-resistant surface coating is formed on the surface of the stator punching. PVD can deposit high-quality, uniform and dense films with good adhesion, wear resistance and corrosion resistance, significantly improving the performance of the substrate, without involving toxic chemicals, and has strong environmental protection. The PVD process can be carried out at low temperatures, which is suitable for temperature-sensitive materials, and the coating is pure and pollution-free, ensuring the quality of high-precision products.

[0056] 3. Optimized cooling water flow path: By providing the water inlet hose 209, the return hose 2010 and the guide plate 208, the cooling water is ensured to flow evenly in the annular cooling chamber 202, thereby improving the efficiency of heat exchange.
