Description

Technical Field

[0001] The invention relates to the technical field of water-cooled motors, and in particular to a motor with a top-mounted water-cooled heat dissipation mechanism. Background Art

[0002] A motor with a water-cooled heat dissipation mechanism is a motor device that integrates a water-cooled heat dissipation system. This motor utilizes the circulation of coolant inside or outside the motor to absorb and take away the heat generated when the motor is running, thereby achieving an effective heat dissipation effect.

[0003] At present, during the operation of the water cooling system of most existing water-cooled motors, impurities in the coolant, such as metal particles and microorganisms, will gradually deposit in the cooling water channels, heat sinks and other parts, forming blockages, which will cause the water cooling system to fail to work normally and even cause motor overheating, burning and other faults. In view of this, we propose a motor with a top-mounted water-cooling heat dissipation mechanism. Summary of the invention

[0004] The main purpose of the present invention is to provide a motor with a top-mounted water-cooling heat dissipation mechanism, which can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the motor with a top-mounted water-cooling heat dissipation mechanism proposed in the present invention comprises a dual-axis motor, the rear of the dual-axis motor is fixedly connected to a frame, the rear output end of the dual-axis motor passes through the fan blades and is fixedly connected to the fan blades, the fan blades are driven to rotate by the dual-axis motor, thereby accelerating the air flow near the heat dissipation pipe, and improving the heat dissipation effect of the heat dissipation pipe, and a water cooling device is provided on the top of the dual-axis motor, and the water cooling device comprises:

[0006] A shell, wherein the shell is fixedly connected to a base, a heat sink is fixedly connected to an outer wall of the base, and the shell is penetrated by a connecting pipe and fixedly connected to the connecting pipe;

[0007] Cover body 1, the cover body 1 is threadedly connected to the connecting pipe, the cover body 1 is threadedly connected to the pipe body, the pipe body is threadedly connected to cover body 2, and a filter block is arranged inside the cover body 2;

[0008] A water outlet pipe, the water outlet pipe passes through the cover body 2 and is rotatably connected to the cover body 2, the end of the water outlet pipe away from the cover body 2 is fixedly connected to the water inlet of the water pump, the water outlet of the water pump is fixedly connected with a Z-shaped pipe 1, the bottom of the water pump is fixedly connected with a fixing plate, and the fixing plate is fixedly connected to the outer wall of the dual-axis motor, the end of the Z-shaped pipe 1 away from the water pump is fixedly connected with a heat dissipation pipe, the heat dissipation pipe passes through the frame and is fixedly connected to the frame, the outer wall of the heat dissipation pipe is fixedly connected with a heat dissipation fin, the outer wall of the heat dissipation pipe is fixedly connected with a heat dissipation fin, the heat dissipation area is increased, and the coolant can flow more fully in the heat dissipation pipe. Heat exchange with the outside world helps to improve the heat dissipation effect. The end of the heat dissipation pipe away from the Z-shaped pipe one is fixedly connected to the Z-shaped pipe two. The end of the Z-shaped pipe two away from the heat dissipation pipe passes through the shell and is fixedly connected to the shell. The diameter of the heat dissipation pipe is smaller than the diameter of the Z-shaped pipe. Under the same flow rate, the smaller the diameter of the heat dissipation pipe, the faster the flow rate of the coolant inside the heat dissipation pipe. The faster flow rate helps to improve the heat dissipation effect of the coolant. When the coolant flows in the heat dissipation pipe with a smaller diameter, its flow state in the pipe is more turbulent, which makes the heat exchange between the coolant and the inner wall of the heat dissipation pipe more sufficient.

[0009] Preferably, the inner wall of the connecting tube is fixedly connected to a fixing seat, the fixing seat is penetrated by the piston rod and is slidably connected to the piston rod, the outer wall of the piston rod is fixedly connected to one end of a spring 1, and the other end of the spring 1 is fixedly connected to the outer wall of the fixing seat.

[0010] Preferably, an inner wall of the cover body is fixedly connected with a cross bar, and an outer wall of the cross bar is fixedly connected with a top rod.

[0011] Preferably, a fixing ring is fixedly connected to the inner wall of the tube body, and a guide rod is fixedly connected to the outer wall of the fixing ring.

[0012] Preferably, the guide rod passes through the filter screen and is slidably connected to the filter screen, one end of the second spring is fixedly connected to the outer wall of the filter screen, and the other end of the second spring is fixedly connected to the outer wall of the fixing ring.

[0013] Preferably, the filter screen is penetrated by a shaft sleeve and is rotatably connected to the shaft sleeve, and the shaft sleeve is penetrated by a rotating shaft and is slidably connected to the rotating shaft.

[0014] Preferably, one end of the rotating shaft is fixedly connected to an impeller. When the coolant flows, the coolant will impact the impeller to rotate, thereby increasing the power for the rotation of the scraper and the cleaning rod. The other end of the rotating shaft is penetrated by the rod body and fixedly connected to the rod body.

[0015] Preferably, the outer wall of the filter screen is fixedly connected with a sleeve body, the sleeve body is rotatably connected with a rotating sleeve, and the sleeve body is provided with an arc groove.

[0016] Preferably, a scraper is fixedly connected to the outer wall of the rotating sleeve, and a plurality of scrapers are provided. The scraper rotates around the outer wall of the filter to clean the outer wall of the filter to prevent impurities from accumulating on the outer wall of the filter and affecting the flow rate of the coolant. This self-cleaning function can ensure that the filter maintains good filtering performance for a long time, ensure the normal operation of the coolant circulation system, and thus ensure the stability of the heat dissipation of the motor. The plurality of scrapers are evenly distributed on the outer wall of the rotating sleeve, and the outer wall of the rotating sleeve is fixedly connected to a limit frame, and the limit frame is slidably connected to the rod body.

[0017] Preferably, the outer wall of the shaft sleeve is fixedly connected with cleaning rods, multiple groups of the cleaning rods are evenly distributed on the rotating sleeve, and multiple groups of the cleaning rods are slidably connected with elastic rods.

[0018] The present invention provides a motor with a top-mounted water-cooling heat dissipation mechanism. It has the following beneficial effects:

[0019] (1) The motor with a top-mounted water-cooling heat dissipation mechanism realizes automatic cleaning of the filter holes through the cooperation of the impeller, the rotating shaft, the cleaning rod and the elastic rod, effectively preventing the problem of filter blockage. At the same time, the filter reciprocates under the action of the second spring, which not only increases the coolant flow rate, but also enhances the impact force of the coolant on the filter holes, further preventing blockage. In addition, the design of the scraper can clean impurities on the outer wall of the filter, ensuring the smooth flow of the coolant, thereby preventing blockage inside the water cooling device.

[0020] (2) The motor has a top-mounted water-cooled heat dissipation mechanism, wherein the outer wall of the heat dissipation tube is fixedly connected with heat dissipation fins, thereby increasing the heat dissipation area. At the same time, through the cooperation with the fan blades, the coolant can more fully exchange heat with the outside when flowing in the heat dissipation tube, thereby effectively improving the heat dissipation effect, enhancing the heat dissipation capacity of the motor, and reducing the risk of motor performance degradation or failure due to overheating.

[0021] (3) The motor with a top-mounted water-cooling heat dissipation mechanism, in the connection structure of the water cooling device, realizes the control of the switch of the water outlet of the connecting pipe during the connection and disassembly process between the shell body and the connecting pipe through the clever cooperation of the push rod, the piston rod and the spring. When performing normal connection operation, the push rod squeezes the piston rod to open the water outlet, allowing the coolant to enter the pipe body. During disassembly, as the shell body is twisted, the force of the push rod on the piston rod is reduced until the piston rod is completely disengaged and the water outlet is closed. This structural design can effectively prevent excessive leakage of coolant when the pipe body is disassembled, thereby avoiding waste of coolant. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the embodiment of the present invention, in order to be able to perform heat dissipation treatment on the dual-axis motor 1, specifically, the water cooling device 4 includes a shell 41, the shell 41 is fixedly connected to a base 411, the outer wall of the base 411 is fixedly connected to a heat sink 412, the shell 41 is penetrated by a connecting pipe 413 and is fixedly connected to the connecting pipe 413, a cover body 1 47 is threadedly connected to the connecting pipe 413, the cover body 1 47 is threadedly connected to a tube body 48, the tube body 48 is threadedly connected to a cover body 2 49, a filter block 491 is provided inside the cover body 2 49, a water outlet pipe 42 penetrates the cover body 2 49 and is rotatably connected to the cover body 2 49, an end of the water outlet pipe 42 away from the cover body 2 49 is fixedly connected to the water inlet of a water pump 43, a water outlet of the water pump 43 is fixedly connected to a Z-shaped pipe 1 44, and a fixing plate is fixedly connected to the bottom of the water pump 43 and fixedly connected to the fixing plate. The fixed plate is fixedly connected to the outer wall of the dual-axis motor 1, and the end of the Z-shaped tube 1 44 away from the water pump 43 is fixedly connected to the heat dissipation pipe 45, the heat dissipation pipe 45 penetrates the frame 2 and is fixedly connected to the frame 2, and the outer wall of the heat dissipation pipe 45 is fixedly connected to the heat dissipation fin 451, and the end of the heat dissipation pipe 45 away from the Z-shaped tube 1 44 is fixedly connected to the Z-shaped tube 2 46, and the end of the Z-shaped tube 2 46 away from the heat dissipation pipe 45 penetrates the shell 41 and is fixedly connected to the shell 41, wherein the heat dissipation pipe 45, the base 411, the heat dissipation fin 412 and the base 411 are made of brass, which is one of the metals with the highest heat transfer efficiency. Therefore, the copper heat dissipation copper sheet can transfer heat from the heat source to the air faster, thereby improving the heat dissipation efficiency. In addition, brass also has good corrosion resistance and oxidation resistance, and can extend the service life;

[0041] Further, the inner wall of the connecting tube 413 is fixedly connected with a fixing seat 414, the fixing seat 414 is penetrated by the piston rod 415 and is slidably connected with the piston rod 415, the outer wall of the piston rod 415 is fixedly connected with one end of a spring 416, the other end of the spring 416 is fixedly connected with the outer wall of the fixing seat 414, the inner wall of the cover body 47 is fixedly connected with a cross bar 471, and the outer wall of the cross bar 471 is fixedly connected with a push rod 472;

[0042] like Fig.11 and Fig.12 As shown, when the cover body 47 is threadedly connected to the connecting pipe 413, during this process, the push rod 472 will contact the piston rod 415 and squeeze the piston rod 415, so that the piston rod 415 moves, and the spring 416 is elastically deformed. When the piston rod 415 moves, the water outlet of the connecting pipe 413 is opened, and the coolant can enter the tube body 48 through the connecting pipe 413. When the tube body 48 needs to be removed, the cover body 47 is twisted again. During this process, the force of the push rod 472 on the piston rod 415 gradually decreases. When the cover body 47 is completely separated from the connecting pipe 413, the piston rod 415 will be reset under the action of the spring 416, and then the water outlet of the connecting pipe 413 will be closed, thereby preventing excessive leakage of the coolant.

[0043] Furthermore, a fixing ring 481 is fixedly connected to the inner wall of the tube body 48, a guide rod 4811 is fixedly connected to the outer wall of the fixing ring 481, the guide rod 4811 penetrates the filter screen 482 and is slidably connected to the filter screen 482, one end of a spring 4812 is fixedly connected to the outer wall of the filter screen 482, and the other end of the spring 4812 is fixedly connected to the outer wall of the fixing ring 481;

[0044] Further, the filter screen 482 is penetrated by the shaft sleeve 4821 and is rotatably connected to the shaft sleeve 4821, the shaft sleeve 4821 is penetrated by the rotating shaft 4822 and is slidably connected to the rotating shaft 4822, one end of the rotating shaft 4822 is fixedly connected to the impeller 4823, the other end of the rotating shaft 4822 is penetrated by the rod body 4820 and is fixedly connected to the rod body 4820, the outer wall of the filter screen 482 is fixedly connected to the sleeve body 4826, the sleeve body 4826 is rotatably connected to the rotating sleeve 4827, and the sleeve body 4826 is provided with an arc groove;

[0045] Further, a scraper 4828 is fixedly connected to the outer wall of the rotating sleeve 4827, and a plurality of scrapers 4828 are provided. The plurality of scrapers 4828 are evenly distributed on the outer wall of the rotating sleeve 4827. A limit frame 4829 is fixedly connected to the outer wall of the rotating sleeve 4827. The limit frame 4829 is slidably connected to the rod body 4820. A cleaning rod 4824 is fixedly connected to the outer wall of the shaft sleeve 4821. The plurality of cleaning rods 4824 are evenly distributed on the rotating sleeve 4827. The plurality of cleaning rods 4824 are slidably connected to the elastic rod 4825.

[0046] In the present invention, when in use, when the dual-axis motor 1 needs to dissipate heat, the water pump 43 is started first. When the water pump 43 is started, the coolant in the water cooling device 4 flows under the force of the water pump 43. When the coolant 43 flows, the coolant will flow inside the base 411. At this time, the heat on the heat sink 412 will be absorbed by the coolant. Subsequently, the coolant that absorbs the heat will enter the tube body 48 through the connecting pipe 413 under the action of the water pump 43. In this process, the coolant will hit the impeller 4823, causing the impeller 4823 to rotate. When the impeller 4823 rotates, the coolant will collide with the impeller 4823. The rotating shaft 4822 fixedly connected to the wheel 4823 rotates, and during this process, the shaft sleeve 4821 slidably connected to the rotating shaft 4822 rotates synchronously. When the shaft sleeve 4821 rotates, the cleaning rod 4824 fixedly connected to the shaft sleeve 4821 rotates synchronously. During the rotation of the cleaning rod 4824, the filter hole will squeeze the elastic rod 4825, so that the elastic rod 4825 is separated from the filter hole. When the elastic rod 4825 overlaps with the filter hole again, the elastic rod 4825 will be repelled into the filter hole again under the elastic force of the reset spring, so that the filter hole can be cleaned to prevent the filter hole from being blocked.

[0047] When the shaft 4822 rotates, the rod 4820 fixedly connected to the shaft 4822 rotates synchronously. During this process, the rod 4820 squeezes the sleeve 4826, causing the filter 482 to move. At the same time, during this process, the spring 4812 undergoes elastic deformation. When the force of the rod 4820 on the sleeve 4826 disappears, the filter 482 returns to its original position under the elastic force of the spring 4812. During this process, the sleeve 4826 is intermittently applied with the rotation of the rod 4820. At the same time, the filter 482 is moved by the spring 4812. 12, the filter screen 482 can make a reciprocating motion, thereby increasing the flow rate of the coolant near the filter screen 482, thereby increasing the impact of the coolant on the filter hole, and preventing the filter hole from being blocked. At the same time, during this process, the rod body 4820 will exert a force on the limit frame 4829, so that the rotating sleeve 4827 rotates. When the rotating sleeve 4827 rotates, the scraper 4828 fixedly connected to the rotating sleeve 4827 rotates synchronously, so that the scraper 4828 cleans the outer wall of the filter screen 482, preventing impurities from accumulating on the outer wall of the filter screen 482, thereby affecting the flow rate of the coolant;

[0048] Subsequently, the coolant will enter the heat dissipation pipe 45 through the Z-shaped pipe 1 44 under the action of the water pump 43. At the same time, the fan blade 3 fixedly connected to the output shaft of the dual-axis motor 1 will rotate under the drive of the dual-axis motor 1. At this time, the fan blade 3 will dissipate heat to the heat dissipation pipe 45, thereby dissipating heat to the coolant. Finally, the cooled coolant will enter the housing 41 under the action of the water pump to dissipate heat to the dual-axis motor 1 again.

[0049] When it is necessary to clean the inside of the tube body 48, the cover body 1 47 is turned. During this process, the force of the push rod 472 on the piston rod 415 gradually decreases. When the cover body 1 47 is completely separated from the connecting pipe 413, the piston rod 415 will close the water outlet of the connecting pipe 413 under the action of the spring 1 416, thereby preventing excessive leakage of the coolant. Then, the cover body 1 47 and the cover body 2 49 are turned again to separate the tube body 48 from the cover body 1 47 and the cover body 2 49, so that the impurities in the tube body 48 can be cleaned. The filter block 491 can be changed, and then the cover body 47 and the cover body 49 are threadedly connected to the tube body 48. Then, when the cover body 47 is threadedly connected to the connecting pipe 413, during this process, the push rod 472 will contact the piston rod 415 and squeeze the piston rod 415, so that the piston rod 415 moves, and the spring 416 undergoes elastic deformation. When the piston rod 415 moves, the water outlet of the connecting pipe 413 is opened, and the coolant can enter the tube body 48 through the connecting pipe 413.
