Description

Technical Field

[0001] The present invention relates to the technical field of water-cooled motors, and specifically relates to a double-layer water channel of a water-cooled motor for enhancing heat exchange efficiency. Background Art

[0002] A water-cooled motor is a motor that uses a water-cooling system for heat dissipation. Compared with traditional air-cooled motors, a water-cooled motor effectively reduces the temperature of the motor through a water-cooling system, providing higher power density and better heat dissipation effect; due to its characteristics of low noise and good cooling effect, a water-cooled motor is widely applicable to high-temperature environments and variable-frequency speed regulation systems; most medium and small water-cooled motors use an external water-cooling method for cooling, so the design of the water channel has become a key technology for the heat dissipation ability of the motor.

[0003] However, most of the traditional water channels of water-cooled motors on the market adopt a single-layer water channel design, either spiral or circuitous; and the single-layer water channel design has only solid-liquid-solid-air exchange channels, and the water flow state in the water channel is single, and the water flow is prone to form laminar flow inside the channel, reducing the heat exchange efficiency; in addition, during the long-term operation of the water channel, due to some particulate impurities and minerals contained in the cooling water, a layer of scale will gradually adhere to the inner wall of the water channel. When the scale accumulates too much, it will reduce the flow surface of the cooling water, causing blockage, and thus affecting the working efficiency and service life of the equipment. Summary of the Invention

An outer water channel is arranged between the outer side of the layered plate and the inner wall of the housing, and an inner water channel is arranged between the inner side of the layered plate and the inner wall of the housing. Communication holes are arranged on the layered plate, and the outer water channel and the inner water channel are interconnected through the communication holes. The plurality of partition plates divide both the outer water channel and the inner water channel into a plurality of cavities, and the plurality of partition plates are arranged in a circular array centered on the cross-sectional center of the layered plate. The diversion grooves are arranged at the ends of the partition plates, and except for the two partition plates arranged on both sides of the top of the layered plate, the diversion grooves on the remaining adjacent partition plates are mutually staggered.

[0007] Specifically, the operating mechanism includes a mounting base, and the bottom of the housing is fixedly connected to the mounting base; a drain pipe and a water inlet pipe are fixedly connected to the housing, and the inner cavity of the drain pipe communicates with the outer water channel, and the inner cavity of the water inlet pipe communicates with the inner water channel.

[0008] Specifically, the filtering mechanism includes a placement frame. The placement frame is arranged inside the water inlet pipe. A filter screen is fixedly connected inside the placement frame. The filter screen is circular. A damping block is fixedly connected to the bottom of the placement frame, and the damping block is engaged with the inside of the water inlet pipe.

[0009] Specifically, the storage mechanism includes a storage frame. The storage frame is fixedly connected to the housing. A pouring pipe is fixedly connected to the storage frame.

A through groove is arranged inside the bottom end of the connecting rod, and the overall shape of the through groove is "I"-shaped. A rubber sealing ring is arranged inside the housing, and the connecting rod abuts against the rubber sealing ring.

[0010] The beneficial effects of the present invention are:

[0011] (1) For the double-layer water channel of the water-cooled motor that enhances heat exchange efficiency of the present invention, during use, the water channel mechanism is arranged inside the housing. Through the water channel mechanism, a double-layer water flow channel can be provided, making the water channel inside the housing more complex. To a certain extent, the Reynolds number of the water flow is increased, ensuring the turbulence of the cooling water, thereby improving the heat exchange efficiency between the inside and outside of the motor body. That is, in actual operation, when the cooling water enters the inside of the housing, it will first enter an area in the inner water channel, and then, successively pass through the diversion grooves provided on different partitions, gradually entering different areas in the inner water channel. Then, it enters the outer water channel through the communication holes. At the same time, part of the cooling water will also enter the outer water channel through the communication holes at the beginning. After entering the outer water channel, it also successively passes through the diversion grooves on different partitions and finally reaches the corresponding drainage part for discharge. After the cooling water in the entire water channel is filled, some water will first overflow to the outer water channel located above the drainage part and then flow back and be discharged again. At the same time, since the diversion grooves on the adjacent partitions except for the two partitions on both sides of the top of the layered plate are arranged in a staggered manner, the cooling water mainly flows in a meandering shape. During the above process, as the cooling water flows, it will also absorb and carry away the heat generated during the operation of the motor body. Thus, a double-layer water flow channel is provided, making the water channel inside the housing more complex. To a certain extent, the Reynolds number of the water flow is increased, ensuring the turbulence of the cooling water, and improving the heat exchange efficiency between the inside and outside of the motor body.

[0012] (2) For the double-layer water channel of the water-cooled motor that enhances heat exchange efficiency of the present invention, during use, the filtering mechanism is arranged inside the operating mechanism. Through the filtering mechanism, it is convenient to filter some particulate impurities and minerals contained in the cooling water when the cooling water flows into the inside of the housing, reduce the accumulation of water scale, ensure the flow area of the cooling water, and thus ensure the working efficiency and service life of the equipment. That is, during use, the placement frame and the filter screen can be inserted into the inside of the water inlet pipe through the damping blocks. Then, when the cooling water flows in, it will first come into contact with the filter screen on the placement frame. Through the filter screen, the cooling water can be filtered, making it convenient to filter some particulate impurities and minerals contained in the cooling water when the cooling water flows into the inside of the housing, reduce the accumulation of water scale, ensure the flow area of the cooling water, and thus ensure the working efficiency and service life of the equipment.

[0013] (3) When the double-layer water channel of the water-cooled motor for enhancing heat exchange efficiency according to the present invention is in use, the storage mechanism is arranged on the housing, and the feeding mechanism is arranged on the storage mechanism. Through the cooperation of the storage mechanism and the feeding mechanism, it is convenient to put a certain amount of scale inhibitor into the cooling water according to the actual situation before starting the water-cooling system. Thus, through the scale inhibitor, a protective film is formed in the water-cooling system to prevent a large amount of hardness ions from depositing on the inner wall of the water channel. At the same time, it can also reduce some existing scale crystals, further reducing the accumulation of scale, ensuring the flow area of the cooling water, and then ensuring the working efficiency and service life of the equipment. That is, when in use, before starting the water-cooling system, according to the actual situation, the user can rotate the rotating block, and the rotation of the rotating block drives the threaded rod to rotate. As the threaded rod rotates, it will drive the connecting rod to rotate and lift together. When the bottom opening of the through groove on the connecting rod is exposed to the outer water channel, the scale inhibitor previously stored in the storage box will be discharged through the through groove and then enter the cooling water. And through the scale, it is convenient to master the addition amount of the scale inhibitor. After the addition is completed, rotate the rotating block in the reverse direction to make the threaded rod drive the connecting rod to rise until the bottom opening of the through groove is embedded in the inner wall of the housing. The rubber sealing ring arranged on the inner wall of the housing also facilitates sealing the opening of the through groove. Through the injection pipe and the sealing cover, it is convenient to add the scale inhibitor into the storage box, so as to conveniently put a certain amount of scale inhibitor into the cooling water according to the actual situation before starting the water-cooling system. Thus, through the scale inhibitor, a protective film is formed in the water-cooling system to prevent a large amount of hardness ions from depositing on the inner wall of the water channel. At the same time, it can also reduce some existing scale crystals, further reducing the accumulation of scale, ensuring the flow area of the cooling water, and then ensuring the working efficiency and service life of the equipment.

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] As Figures 1 - 11 shown, a double-layer water channel of a water-cooled motor for enhancing heat exchange efficiency according to the present invention includes a housing 1, a motor body 2 is arranged inside the housing 1, an operating mechanism 3 is arranged on the housing 1, a water channel mechanism 4 is arranged inside the housing 1, a filter mechanism 5 is arranged inside the operating mechanism 3, a storage mechanism 6 is arranged on the housing 1, and a feeding mechanism 7 is arranged on the storage mechanism 6;

[0029] The water channel mechanism 4 includes a layered plate 401, which is fixedly connected to the inside of the housing 1. A plurality of partition plates 402 are fixedly connected to the layered plate 401. Two diversion channels 403 are provided on the partition plates 402, and the two diversion channels 403 are respectively arranged on both sides of the layered plate 401. An outer water channel 406 is provided between the outer side of the layered plate 401 and the inner wall of the housing 1, and an inner water channel 405 is provided between the inner side of the layered plate 401 and the inner wall of the housing 1. A communication hole 404 is provided on the layered plate 401, and the outer water channel 406 and the inner water channel 405 are interconnected through the communication hole 404. The plurality of partition plates 402 divide both the outer water channel 406 and the inner water channel 405 into a plurality of cavities, and the plurality of partition plates 402 are arranged in a circular array centered on the center of the cross-section of the layered plate 401. The diversion channels 403 are arranged at the ends of the partition plates 402, and except for the two partition plates 402 arranged on both sides of the top of the layered plate 401, the diversion channels 403 on the remaining adjacent partition plates 402 are arranged in a staggered manner; in use, the water channel mechanism 4 is arranged inside the housing 1. Through the water channel mechanism 4, a double-layer water flow channel can be provided, making the water channel inside the housing 1 more complex, increasing the Reynolds number of the water flow to a certain extent, ensuring the turbulence of the cooling water, and thus improving the heat exchange efficiency between the inside and the outside of the motor body 2; that is, in actual operation, when the cooling water enters the inside of the housing 1, it will first enter a region in the inner water channel 405, and then, successively pass through the diversion channels 403 provided on different partition plates 402, gradually enter different regions in the inner water channel 405, and then enter the outer water channel 406 through the communication hole 404. At the same time, part of the cooling water will also enter the outer water channel 406 through the communication hole 404 at the beginning. After entering the outer water channel 406, it will also successively pass through the diversion channels 403 on the different partition plates 402 and finally reach the corresponding drainage part for discharge. After the cooling water in the entire water channel is filled, part of the water will first overflow to the outer water channel 406 located above the drainage part and then flow back and drain out again. At the same time, since except for the two partition plates 402 on both sides of the top of the layered plate 401, the diversion channels 403 on the remaining adjacent partition plates 402 are arranged in a staggered manner, the cooling water mainly flows in a meandering shape. In the above process, as the cooling water flows, it will also absorb and carry away the heat generated during the operation of the motor body 2, thereby providing a double-layer water flow channel, making the water channel inside the housing 1 more complex, increasing the Reynolds number of the water flow to a certain extent, ensuring the turbulence of the cooling water, and improving the heat exchange efficiency between the inside and the outside of the motor body 2.

[0031] Specifically, as Figure 2 and Figure 8 shown, the filtering mechanism 5 includes a placement frame 501. The placement frame 501 is arranged inside the water inlet pipe 303. A filter screen 502 is fixedly connected inside the placement frame 501. The filter screen 502 is circular in shape. A damping block 503 is fixedly connected to the bottom of the placement frame 501, and the damping block 503 is engaged with the inside of the water inlet pipe 303; during use, the filtering mechanism 5 is arranged inside the operating mechanism 3. Through the filtering mechanism 5, it is convenient to filter some particulate impurities and minerals contained in the cooling water to a certain extent when the cooling water flows into the housing 1, reduce the accumulation of scale, ensure the flow area of the cooling water, and thus ensure the working efficiency and service life of the equipment; that is: during use, the placement frame 501 and the filter screen 502 can be inserted into the water inlet pipe 303 through the damping block 503. When the cooling water flows in, it will first contact the filter screen 502 on the placement frame 501. Through the filter screen 502, the cooling water can be filtered, so as to conveniently filter some particulate impurities and minerals contained in the cooling water to a certain extent when the cooling water flows into the housing 1, reduce the accumulation of scale, ensure the flow area of the cooling water, and thus ensure the working efficiency and service life of the equipment.

[0032] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 10 and Figure 11As shown, the storage mechanism 6 includes a storage frame 601, the shell 1 is fixedly connected with the storage frame 601, the storage frame 601 is fixedly connected with an injection tube 602, the injection tube 602 is provided with a cover 603, and the storage frame 601 is provided with a dial 604; the feeding mechanism 7 includes a placement seat 701, the storage frame 601 is fixedly connected with a placement seat 701, the placement seat 701 is provided with a rotating block 702, the rotating block 702 is fixedly connected with a threaded rod 703, the threaded rod 703 is threadedly connected to the inside of the placement seat 701, and the threaded rod 703 is fixedly connected with a connecting rod 704, the connecting rod 704 is slidably connected to the inside of the shell 1, the bottom end of the connecting rod 704 extends to the outer water channel 406, the threaded rod 703 is fixedly connected with a slider 706, and the slider 706 It is slidably connected to the interior of the mounting seat 701, and a through groove 705 is provided inside the bottom end of the connecting rod 704, and the through groove 705 is in the shape of an "I" character as a whole. A rubber sealing ring 707 is provided inside the shell 1, and the connecting rod 704 abuts against the rubber sealing ring 707; when in use, the storage mechanism 6 is arranged on the shell 1, and the feeding mechanism 7 is arranged on the storage mechanism 6. Through the cooperation of the storage mechanism 6 and the feeding mechanism 7, it is convenient to add a certain amount of scale inhibitor into the cooling water according to the actual situation before starting the water cooling system, so that a protective film is formed in the water cooling system through the scale inhibitor to prevent the hardness ions from being deposited on the inner wall of the water channel in large quantities, and at the same time, it can also reduce part of the existing scale crystals, so as to further reduce the accumulation of scale, ensure the circulation surface of the cooling water, and thus ensure the working efficiency and life of the equipment;That is, during use, before starting the water cooling system, according to the actual situation, the user can rotate the rotating block 702. The rotation of the rotating block 702 drives the rotation of the threaded rod 703. As the threaded rod 703 rotates, it drives the connecting rod 704 to rotate and lift at the same time. When the bottom opening of the through groove 705 on the connecting rod 704 is exposed to the outer water channel 406, the scale inhibitor previously stored inside the storage box 601 will be discharged through the through groove 705 and then enter the cooling water. Through the dial 604, it is convenient to master the dosage of the scale inhibitor. After the addition is completed, rotate the rotating block 702 in the reverse direction to make the threaded rod 703 drive the connecting rod 704 to rise until the bottom opening of the through groove 705 is embedded in the inner wall of the housing 1. The rubber sealing ring 707 provided on the inner wall of the housing 1 also facilitates sealing the opening of the through groove 705. Through the injection pipe 602 and the cover 603, it is convenient to add the scale inhibitor into the storage box 601, so as to conveniently put a certain amount of scale inhibitor into the cooling water according to the actual situation before starting the water cooling system. Thus, through the scale inhibitor, a protective film is formed in the water cooling system to prevent a large amount of hardness ions from depositing on the inner wall of the water channel. At the same time, it can also reduce part of the existing scale crystals, further reducing the accumulation of scale, ensuring the flow surface of the cooling water, and thus ensuring the working efficiency and service life of the equipment.

[0033] When the present invention is in use, first, through the mounting base 301, it is convenient to fixedly install the entire device. Through the drain pipe 302 and the water inlet pipe 303, it is convenient for the discharge and inflow of cooling water respectively. In actual operation, when the cooling water enters the interior of the housing 1, it will first enter a region in the inner water channel 405, and then, successively pass through the diversion grooves 403 provided on different partition plates 402, gradually enter different regions in the inner water channel 405, and then enter the outer water channel 406 through the communication holes 404. At the same time, part of the cooling water will also enter the outer water channel 406 through the communication holes 404 at the beginning. After entering the outer water channel 406, it will also successively pass through the diversion grooves 403 on different partition plates 402 and finally reach the corresponding drainage part for discharge. After the cooling water in the entire water channel is filled, part of the water will first overflow to the outer water channel 406 located above the drainage part and then flow back and be discharged again. At the same time, since the diversion grooves 403 on the adjacent partition plates 402, except for the two partition plates 402 on both sides of the top of the layered plate 401, are staggered with each other, the cooling water mainly flows in a meandering shape. In the above process, as the cooling water flows, it will also absorb and carry away the heat generated during the operation of the motor body 2, thus providing a double-layer water flow channel, making the water channel inside the housing 1 more complex, increasing the Reynolds number of the water flow to a certain extent, ensuring the turbulence of the cooling water, and improving the heat exchange efficiency between the inside and the outside of the motor body 2. In addition, the placement frame 501 and the filter screen 502 can be inserted into the interior of the water inlet pipe 303 through the damping block 503. Then, when the cooling water flows in, it will first contact the filter screen 502 on the placement frame 501. Through the filter screen 502, the cooling water can be filtered, so as to facilitate the filtration of some particulate impurities and minerals contained in the cooling water when the cooling water flows into the interior of the housing 1, reduce the accumulation of scale, ensure the flow surface of the cooling water, and thus ensure the working efficiency and service life of the equipment.Further, before starting the water cooling system, according to the actual situation, the user can rotate the rotating block 702. Then, the rotation of the rotating block 702 drives the rotation of the threaded rod 703. As the threaded rod 703 rotates, it will drive the connecting rod 704 to rotate and lift together. When the bottom opening of the through groove 705 on the connecting rod 704 is exposed to the outer water channel 406, the scale inhibitor previously stored inside the storage frame 601 will be discharged through the through groove 705 and then enter the cooling water. Through the dial 604, it is convenient to master the dosage of the scale inhibitor. After the addition is completed, rotate the rotating block 702 in the reverse direction to make the threaded rod 703 drive the connecting rod 704 to rise until the bottom opening of the through groove 705 is embedded in the inner wall of the housing 1. The rubber sealing ring 707 provided on the inner wall of the housing 1 also facilitates sealing the opening of the through groove 705. Through the injection pipe 602 and the cover 603, it is convenient to add the scale inhibitor into the storage frame 601, so that before starting the water cooling system, a certain amount of scale inhibitor can be put into the cooling water according to the actual situation. Thus, through the scale inhibitor, a protective film is formed in the water cooling system to prevent a large amount of hardness ions from depositing on the inner wall of the water channel. At the same time, some existing scale crystals can also be reduced, further reducing the accumulation of scale, ensuring the flow surface of the cooling water, and thus ensuring the working efficiency and service life of the equipment.
