Description

Technical Field

[0001] The invention relates to the technical field of motor heat dissipation devices, and in particular to a water jacket component of a casing with a double water channel structure. Background Art

[0002] There are many ways to dissipate heat from a motor, but the most commonly used are air cooling and water cooling. However, the cooling efficiency of air cooling is lower than that of water cooling. In the invention patent with application number CN202311059457.5, a water-cooled heat dissipation device for a motor is disclosed, including a housing, a stator, a rotor, a heat dissipation mechanism, a sealing mechanism and a cooling mechanism. By arranging the heat dissipation mechanism inside the motor, the cooling efficiency can be changed according to the rotational speed of the motor itself, so that the motor always operates within the most suitable temperature range, thereby increasing the service life of the motor.

The device has a complex structure, resulting in high actual use and maintenance costs, and is not suitable for existing transmission motors, which limits its actual use scope; 2. When the device is cooling, it actually still uses the traditional single-circuit circulation method, which easily leads to a larger cooling liquid flow path. At the end of the cooling liquid flow, the actual temperature of the cooling liquid is higher, and the cooling effect on one side of the motor becomes worse, which easily affects the life of the motor.

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.

The heat dissipation mechanism includes a sleeve 2. The sleeve 2 is made of a metal material with high temperature corrosion and good heat conduction, and the internal size is matched with the size of the motor 1 shell. The sleeve 2 is sleeved on the shell of the motor 1 for comprehensive heat conduction. A connecting unit 3 is disposed on the outside of the sleeve 2. Two groups of spiral tubes 4 are sleeved on the outside of the sleeve 2. The spiral tubes 4 are used for circulating cooling liquid to absorb the heat generated by the motor 1.

[0022] In this embodiment, the sleeve 2 is used to transfer the heat of the motor 1 as a whole, and at the same time, the pump 9 drives the cooling liquid in the inner cavity 7 to enter the interior of the spiral tube 4 through one end of the spiral tube 4, and the heat transferred by the sleeve 2 is absorbed by the flow of the cooling liquid. The cooling liquid after heat exchange flows back to the interior of the inner cavity 7 through the other end of the spiral tube 4 and the one-way valve 8, and heat is transferred through the arc plate 6, the connecting seat 10 and the fin plate 12, and the heat is dissipated through the surfaces of the fin plate 12 and the connecting seat 10 and the interior of the through groove 11. At the same time, the heat is dissipated in a zone through two groups of spiral tubes 4, thereby improving the heat dissipation efficiency and effect on both sides of the motor 1.

[0023] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 1 , Attachment Figure 3 ; The connecting unit 3 includes a mounting plate 31, the outer surface of the mounting plate 31 is fixedly connected to the outer surface of the motor 1, the mounting plate 31 and the sleeve 2 can be directly fixed by welding, or fixed by bolting, the outer surface of the mounting plate 31 is fixedly connected to the outer surface of the sleeve 2, and the outer surface of the mounting plate 31 is fixedly connected with a fixed cylinder 32, the fixed cylinder 32 can further protect the housing of the motor 1, and prevent the water vapor in the outside air from condensing and adhering to the housing of the motor 1, causing corrosion and pollution of the housing of the motor 1. One end of the fixed cylinder 32 is fixedly connected to the mounting plate 31 by a sealing ring and bolting, and the fixed cylinder 32 is sleeved in the sleeve The outside of the tube 2, the outer surface of the connecting seat 10 is fixedly connected to the body of the fixed tube 32, the inside of the solid tube 32 is fixedly connected with a solid ring 33, the inside of the solid ring 33 is movably connected with a push ring 34, the side where the push ring 34 and the solid ring 33 are in contact is provided with an oblique chamfer, and the sealing and stability of the connection are improved by the oblique abutment, the inside of the push ring 34 is threadedly connected to the outer surface of the sleeve 2, and a groove 35 is provided on the outer surface of the push ring 34, and a sealing ring 36 is movably connected inside the groove 35. The cross-section of the sealing ring 36 is circular to facilitate the abutment contact with the oblique chamfer of the solid ring 33, and the outer surface of the sealing ring 36 is movably connected to the inside of the solid ring 33.

[0024] In this embodiment, the sleeve 2 is first fixed to the mounting plate 31, and then the sleeve 2 is sleeved on the housing of the motor 1 from one side of the output shaft of the motor 1, and the mounting plate 31 is in contact with the surface of one side of the output shaft of the motor 1, and then the mounting plate 31 is fixed to the housing of the motor 1 by bolt connection, and then the fixed sleeve 32 is sleeved on the outside of the sleeve 2 and the motor 1 from the other side of the motor 1, and the spiral tube 4 is sleeved on the outside of the motor 1 and in contact with the surface of the sleeve 2, and at the same time, one end of the fixed sleeve 32 is fixed to the surface of the mounting plate 31 by a sealing ring and bolt connection, and then the sealing ring 36 is installed on the groove 35 of the butt ring 34 by interference fit, and then a waterproof tape is wrapped around the connected end of the sleeve 2, and then the butt ring 34 is connected to the external thread of one end of the sleeve 2, and at the same time, the sealing between the sleeve 2 and the fixed sleeve 32 is achieved by the oblique butt of the butt ring 34 and the sealing ring 36 with the fixed ring 33.

[0025] Embodiment 3: Based on Embodiment 2, refer to the attached Figure 1 , Attachment Figure 4 ; The expansion unit 5 includes a water tank 51, which is opened on the body of the spiral tube 4 and is in a through state. A film 52 is arranged on the outside of the water tank 51. The film 52 is made of a material that is resistant to high temperature corrosion, has good elasticity and is resistant to fatigue. The outer surface of the film 52 is fixedly connected to the outer surface of the spiral tube 4. The outer surface of the film 52 is fixedly connected to a pull plate 54, and the pull plate 54 can limit the expansion path of the film 52. The outer surface of the pull plate 54 is movably connected to a fixed frame 55. The outer surface of the fixed frame 55 is fixedly connected to the outer surface of the spiral tube 4. The outer surface of the fixed frame 55 is fixedly connected to a spring rod 56. The elastic force of the spring rod 56 can offset the hydraulic pressure of the cooling liquid. The output end of the spring rod 56 is fixedly connected to the outer surface of the pull plate 54.

[0026] In this embodiment, when the cooling liquid flows normally, the spring rod 56 offsets the hydraulic pressure to prevent the film 52 from expanding, which causes the pump 9 to increase power consumption. At the same time, when there is abnormally high temperature locally, the film 52 expands, and the pull plate 54 and the fixed frame 55 limit its path. At the same time, the output end of the spring rod 56 is compressed to facilitate the restoration of the film 52. When the film 52 expands, the contact area with the sleeve 2 is increased, and the internal capacity of its coverage area is increased. The cooling liquid inside the spiral tube 4 enters the expansion area through the water tank 51. By increasing the capacity of the cooling liquid, the amount of heat absorbed is increased, thereby improving the heat dissipation efficiency.

[0027] Embodiment 4: Based on Embodiment 3, refer to the attached Figure 4 , Attachment Figure 5 ; The trigger module 53 is arranged outside the film 52. The trigger module 53 includes a folding sheet 531. The folding sheet 531 is made of memory metal. When subjected to high temperature, it folds to shorten its own length. The outer surface of the folding sheet 531 is movably connected to the outer surface of the sleeve 2. One end of the folding sheet 531 is fixedly connected to the outer surface of the fixed frame 55. The other end of the folding sheet 531 is provided with a hanging ring 532. The ring hole of the hanging ring 532 is clamped with a hook 533. The clamping of the hanging ring 532 and the hook 533 facilitates the disassembly and assembly connection between the folding sheet 531 and the film 52. It can also be replaced by other connection methods with the same function. The outer surface of the hook 533 is fixedly connected to the outer surface of the pull plate 54. The outer surface of the lifting ring 532 is fixedly connected with a slide 534, and the outer surface of the slide 534 is fixedly connected to the other end of the folding piece 531. The outer surface of the slide 534 is fixedly connected with a telescopic rod 535. The telescopic rod 535 and the slide 534 can limit the movement path of the folding piece 531. The outer surface of the telescopic rod 535 is fixedly connected to the outer surface of the fixed frame 55. The outer surface of the slide 534 is movably connected with a column 536. The column 536 is made of pressure-sensitive material. After being compressed, its own resistance value decreases. By being connected in series with the circuit of the pump 9, the power of the pump 9 can be automatically increased after a trigger signal is generated. One end of the column 536 is fixedly connected to the outer surface of the fixed frame 55.

[0028] In this embodiment, when abnormally high temperature appears locally in the motor 1, the cooling liquid conventional sulfuric acid cannot quickly dissipate heat, so that the folding sheet 531 absorbs heat and heats up, thereby folding and shrinking, and through the action of the slide 534, the ring 532 and the hook 533, the pull plate 54 pulls the film 52 to move and expand, and at the same time the slide 534 and the telescopic rod 535 limit the movement path of the folding sheet 531 and the film 52, and the slide 534 presses against the abutment column 536 during movement, so that the resistance value of the abutment column 536 itself is reduced, thereby increasing the power of the pump 9, so that the cooling liquid increases the flow rate and flow, and enters the expansion area of ​​the film 52 through the cooling liquid, and accurately and quickly dissipates the abnormally high temperature locally. When the local temperature is normal and the temperature of the folding sheet 531 returns to normal, the folding sheet 531 stretches to a straight state, thereby pushing the film 52 to recover, and the slide 534 follows the movement to break away from the abutment against the abutment column 536, so that the power of the pump 9 is restored to a normal value.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
