Description

Technical Field

[0001] The present invention relates to the technical field of generators, and in particular to a generator with excellent heat dissipation effect. Background Art

[0002] When a conductor in a magnetic field cuts the magnetic lines of force, an electromotive force is generated in the conductor. If a closed circuit is formed, an electric current is generated. This process involves the rotation of the rotor and the fixation of the stator. When the rotor rotates, the conductor cuts the magnetic lines of force, generates an electromotive force, and forms alternating current. The current is output through an external circuit for use by external devices. This process will cause a large amount of heat to be generated inside the generator. If the heat is not dissipated in time, the temperature of the generator will rise, affecting its efficiency and life, and may even cause damage to the generator. The cooling system of a liquid-cooled generator uses liquid coolant to manage and reduce the heat generated during generator operation.

[0003] However, in the prior art, in the structure of the liquid-cooled generator, the shape and distribution of the cooling channel play a decisive role in the cooling efficiency. The linear cooling channel is simple in design and easy to process, but it will cause uneven flow of the coolant, especially in the longer part of the generator, thus affecting the overall cooling effect. Secondly, the spiral cooling channel, through its spiral structure, allows the coolant to flow longer inside the generator, improving the heat exchange efficiency, but this complex structure will lead to the appearance of dead zones of flow. The wavy cooling channel, in addition, is the grid-shaped cooling channel that can provide a multi-directional flow path, greatly improving the cooling efficiency. This design is extremely complex, not only with high manufacturing costs, but also more difficult to maintain and clean. Regardless of the shape and structure of the cooling channel, the circulation path of the coolant always follows, entering from the liquid inlet, passing through the cooling channel to absorb internal heat, and then discharged from the liquid outlet, thus forming a closed circulation loop. However, in this process, due to the different heat concentration areas of the rotor and the stator, and due to the rotation of the rotor, it is transferred to the external position, which will change, making the heat distribution inside the generator unbalanced, and the unbalanced position changes. The degree of cooling required in different parts of the generator is different, but the cooling effect of all areas inside the existing generator is the same. When the coolant flows in the channel, its heat dissipation efficiency will gradually decrease, and it is impossible to accurately dissipate heat in areas with higher heat. Therefore, some generators use temperature sensors and control systems to monitor the temperature of various parts of the generator and adjust the flow and temperature of the coolant to achieve more uniform heat dissipation. However, the optimized cooling channel is still difficult to adapt to the complex heat distribution inside the generator. In addition, since the temperature sensor cannot completely cover the entire generator equipment, the temperature sensor not only cannot fully control the temperature changes in the generator, but also increases the overall weight and volume of the generator.

[0004] Therefore, a generator with excellent heat dissipation effect is proposed, which can ensure that the internal temperature of the generator is balanced. Summary of the invention

[0007] Furthermore, the liquid inlet of the liquid inlet sleeve is located at the top of the liquid inlet sleeve, the liquid inlet sleeve is located in the middle of the left half shell, the right half shell, the left half shell and the heat absorption sleeve are interconnected, and the heat absorption sleeve is located between the right half shell and the left half shell.

[0008] Furthermore, the extrusion member includes a sleeve shaft rotatably connected to the inside of the left half shell, a thin-film turbine fixedly connected to the outside of the sleeve shaft, and a half-disc block fixedly connected to the side of the thin-film turbine away from the left half shell. When the inner hollow arc shell is in the initial position, the half-disc block does not contact the inner hollow arc shell.

[0009] Furthermore, the heat absorption sleeve includes a circular sleeve sleeved on the outside of the stator, a plurality of outer heat sinks arranged at equal angles and fixedly connected to the outside of the circular sleeve, and a plurality of inner heat sinks arranged at equal angles and fixedly connected to the outside of the circular sleeve, and the number of the outer heat sinks is equal to that of the inner heat sinks.

[0010] Furthermore, the outer heat sink contacts the inner wall of the outer shell, a flow zone is formed between the two outer heat sinks, the outer shell, the right half shell and the flow zone are interconnected, and the inner heat sink and the inner hollow arc shell are both located inside the flow zone.

[0011] Furthermore, the height of the inner hollow arc shell is smaller than the height of the outer heat sink, and the height of the inner heat sink is smaller than the height of the inner hollow arc shell. The inner heat sink is located inside the inner hollow arc shell, and a circular ring is clamped on one side of the circular sleeve close to the right half shell, and the height of the circular ring is equal to that of the inner heat sink.

[0012] Furthermore, the inner hollow arc shell is provided with a square notch at a position close to the closed surface, and the inner hollow arc shell is provided with perforations at equal intervals.

[0014] Furthermore, when the inner hollow arc shell is in the initial position, one end away from the installation axis is in contact with the heat absorbing sleeve, and when the memory metal strip is heated, it pushes the inner hollow arc shell to move, so that the inner hollow arc shell moves from the initial position to the set position.

When the temperature of the inner core is uneven, it is received by the heat-absorbing sleeve, and then the state of the inner hollow arc shell is changed by the memory metal strip, so that the contact area of ​​the coolant heat-absorbing sleeve at the corresponding position is increased, and the heat dissipation efficiency at a higher and more stable position is enhanced to ensure the uniform internal temperature of the liquid-cooled generator, which can ensure the operating efficiency of the shaft core, prevent material aging caused by local overheating, reduce the impact of thermal stress on the overall structure, increase the reliability and stability of the equipment, extend the service life of the equipment and maintain its high-performance operation.

[0018] 2.

At the same time, change the amount of coolant absorbed by different heat dissipation components to achieve heat absorption and heat dissipation corresponding to the local heating position.

[0019] 3. The deformation of the memory metal strip can not only ensure that the position of the inner hollow arc shell is changed at a specific temperature, but also drive the inner hollow arc shell. When the heat reaches the set value, the memory metal strip is driven to rotate, so that the coolant moves from the square notch position, thereby absorbing a large amount of heat in the process to ensure uniform heat dissipation.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figure 1-7, is an embodiment of the present invention, providing a generator with excellent heat dissipation effect, including an axis core 1, an inner core 2 arranged outside the axis core 1, an outer shell 3 arranged outside the inner core 2, a right half shell 4 and a left half shell 5 respectively arranged on the left and right sides of the outer shell 3, a heat absorption sleeve 6 fixedly arranged outside the inner core 2, an extrusion piece 7 rotatably connected to the inside of the left half shell 5, a plurality of mounting shafts 8 equiangularly arranged and clamped on one side of the heat absorption sleeve 6, an inner hollow arc shell 9 rotatably connected to the mounting shaft 8 at one end, a memory metal strip 10 hinged between the inner hollow arc shell 9 and the heat absorption sleeve 6, a liquid outlet sleeve 11 fixed to the outside of the right half shell 4, and a liquid inlet sleeve fixed to the outside of the left half shell 5. 12, the inner hollow arc shell 9 and the memory metal strip 10 correspond to the number and position of the installation shaft 8 one by one, the shaft core 1 is rotatably connected to the center of the left half shell 5 and the right half shell 4, the inner core 2 includes a rotor 21 fixedly connected to the outside of the shaft core 1, and a stator 22 fixedly clamped between the right half shell 4 and the left half shell 5, the stator 22 is located on the outside of the rotor 21, and the heat absorption sleeve 6 is sleeved on the outside of the stator 22. The inner hollow arc shell 9 includes an initial position and a setting position. When the inner hollow arc shell 9 is in the initial position, it is parallel to the central axis of the shaft core 1. When the inner hollow arc shell 9 is in the setting position, one end of the inner hollow arc shell 9 contacts the inside of the outer shell 3 to increase the contact area and time of the coolant and the heat source, thereby improving the heat dissipation efficiency.

[0031] It can be understood that the memory metal strip 10 is also called shape memory alloy, which is a material with special properties that can "memorize" and restore to a preset shape under specific conditions. Its material is usually nickel-titanium alloy. At this time, the material can be easily shaped, and when the temperature rises to a certain value, the material will return to the preset shape.

[0032] Specifically, the two ends of the memory metal strip 10 are made of conventional iron, and the other parts are all memory alloys, so that the memory metal strip 10 stretches after being affected by temperature. Even if the memory metal strip 10 is in a stretched state, it is not completely straight, but the bending angle is reduced. At this time, if the extrusion piece 7 squeezes the inner hollow arc shell 9, the memory metal strip 10 can bend at the original bending point, and then complete the transformation into the original bending state.

[0033] Reference Figure 1-3 The liquid inlet of the liquid inlet sleeve 12 is located at the top of the liquid inlet sleeve 12, the liquid inlet sleeve 12 is located in the middle of the left half shell 5, the right half shell 4, the left half shell 5 and the heat absorption sleeve 6 are interconnected, and the heat absorption sleeve 6 is located between the right half shell 4 and the left half shell 5.

[0034] Specifically, when the coolant enters the right half shell 4 from the liquid inlet of the liquid inlet sleeve 12, since the liquid inlet of the liquid inlet sleeve 12 is located at the top of the liquid inlet sleeve 12, the coolant moves downward first after entering, and since the right half shell 4 moves to the left half shell 5, its flow direction is single, so that the extrusion part 7 can rotate slowly, and the liquid inlet sleeve 12 is located at the middle edge of the left half shell 5, not at the center of the circle, so that after the coolant enters the right half shell 4, it will not diffuse to both sides, and only needs to impact in one direction to ensure the stability of the impact force.

[0035] Reference Figure 3-6 The extrusion member 7 includes a sleeve shaft 71 rotatably connected to the inside of the left half shell 5, a thin-film turbine 72 fixedly connected to the outside of the sleeve shaft 71, and a half-disc block 73 fixedly connected to the side of the thin-film turbine 72 away from the left half shell 5. When the inner hollow arc shell 9 is in the initial position, the half-disc block 73 does not contact the inner hollow arc shell 9. At this time, the two will not collide and avoid friction. After the inner hollow arc shell 9 rotates, the half-disc block 73 will squeeze the side of the inner hollow arc shell 9. The extrusion member 7 is made of lightweight material as a whole and can better receive power.

[0036] Reference Figure 3-6 The heat absorption sleeve 6 includes a circular sleeve 61 sleeved on the outside of the stator 22, a plurality of outer heat sinks 62 arranged at equal angles and fixedly connected to the outside of the circular sleeve 61, and a plurality of inner heat sinks 63 arranged at equal angles and fixedly connected to the outside of the circular sleeve 61. The number of the outer heat sinks 62 is equal to the number of the inner heat sinks 63, thereby absorbing the heat of the rotor 21 and the stator 22 at multiple positions.

[0037] Reference Figure 2-6 The outer heat sink 62 contacts the inner wall of the outer shell 3, and a flow interval 621 is formed between the two outer heat sinks 62. The outer shell 3, the right half shell 4 and the flow interval 621 are interconnected, and the coolant can flow among the three, that is, it enters from the liquid inlet sleeve 12 through the flow interval 621 and the outer shell 3, and then reaches the right half shell 4. The inner heat sink 63 and the inner hollow arc shell 9 are both located inside the flow interval 621. When the coolant passes through the flow interval 621, it will cover the area of ​​the inner hollow arc shell 9 and the inner heat sink 63.

[0038] Reference Figure 2-6The height of the inner hollow arc shell 9 is less than the height of the outer heat sink 62, so that the coolant can flow from the top of the inner hollow arc shell 9 to the inside of the right half shell 4, thereby passing through the outer heat sink 62 and absorbing the heat of the outer heat sink 62, and the height of the inner heat sink 63 is less than the height of the inner hollow arc shell 9, and the inner heat sink 63 will not always be in a state of absorbing heat. When the inner hollow arc shell 9 moves, the circular sleeve 61, the outer heat sink 62 and the inner heat sink 63 are simultaneously absorbed by heat, so that the higher the local temperature, the corresponding inner hollow arc shell 9 will rotate, and the better the heat dissipation effect on the overheated position. The inner heat sink 63 is located inside the inner hollow arc shell 9, and a circular ring 611 is clamped on one side of the circular sleeve 61 close to the right half shell 4. The height of the circular ring 611 is equal to that of the inner heat sink 63. The circular ring 611 is used to block the coolant flowing from the bottom of the inner hollow arc shell 9 to ensure the uniform absorption of heat by the overall coolant.

[0039] Reference Figure 1-6 A square notch 91 is provided at a position of the inner hollow arc shell 9 close to the closed surface 93, and perforations 92 are provided at equal intervals on the inner hollow arc shell 9. The position where the inner hollow arc shell 9 is connected to the memory metal strip 10 is the closed surface 93. The position of the inner hollow arc shell 9 close to the half disk block 73 is a compressed arc surface 94. The perforation 92 is located between the closed surface 93 and the square notch 91. When the inner hollow arc shell 9 rotates and contacts the inside of the outer shell 3, the half disk block 73 will squeeze the compressed arc surface 94 of the inner hollow arc shell 9 during rotation, causing the inner hollow arc shell 9 to rotate and move back.

[0040] Specifically, after entering the right half shell 4, the coolant will first fill the space of the outer shell 3, and the inner hollow arc shell 9 is located inside it. The gap between the inner hollow arc shell 9 and the circular sleeve 61 will also be filled with coolant due to the circular sleeve 61 and the outer heat sink 62 opened by the inner hollow arc shell 9. At this time, after the coolant between the inner hollow arc shell 9 and the circular sleeve 61 is filled, the external coolant is blocked by the inner hollow arc shell 9, and the exchange efficiency with the coolant between the inner hollow arc shell 9 and the circular sleeve 61 becomes slower. The memory metal strip 10 is below the closed surface 93 and is therefore in a semi-closed state. At this time, the temperature between the inner hollow arc shell 9 and the circular sleeve 61 will change with the external heat sink 62. Therefore, when the temperature around the memory metal strip 10 increases, the memory metal strip 10 will be deformed.

[0041] Reference Figure 1-7 The mounting shaft 8 is clamped between the two outer heat sinks 62, and the mounting shaft 8 is located on the side of the outer heat sink 62 close to the right half shell 4. One end of the inner hollow arc shell 9 is rotatably connected to the mounting shaft 8, and the end of the inner hollow arc shell 9 connected to the mounting shaft 8 is never in contact with the heat absorption sleeve 6.

[0042] Reference Figure 1-7When the inner hollow arc shell 9 is in the initial position, the end away from the installation shaft 8 is in contact with the heat absorption sleeve 6. When the memory metal strip 10 is heated, it pushes the inner hollow arc shell 9 to move, so that the inner hollow arc shell 9 moves from the initial position to the set position.

[0043] The length of the inner hollow arc shell 9 is greater than the circular sleeve 61, so that one end of the inner hollow arc shell 9 extends out of the circular sleeve 61, and this position is a pressure arc surface 94 to withstand the extrusion of the half disk block 73. The length of the circular sleeve 61 and the outer heat sink 62 is equal. The length of the inner heat sink 63 is greater than the square slot 91 and less than the circular sleeve 61, ensuring that the inner heat sink 63 can absorb the heat of the rotor 21 and the stator 22. At the same time, the coolant needs to pass through the closed surface 93 first and then pass through the square slot 91, so that the coolant can effectively absorb the heat of the inner heat sink 63, ensuring stable heat dissipation of the rotor 21 and the stator 22.

[0044] The working principle of the present invention is as follows: the coolant rushes into the liquid inlet on the liquid sleeve 12 and enters the interior of the left half shell 5, and then impacts the thin-film turbine 72, causing the half disk block 73 to rotate slowly, and the thin-film turbine 72 drives the sleeve shaft 71 and the half disk block 73 to rotate synchronously, and the coolant will flow between the two outer heat sinks 62 to reach the inside of the right half shell 4, and the outer heat sink 62 will absorb the outer heat sink 62, and then discharge it through the liquid outlet sleeve 11, and when the coolant passes through the inner hollow arc shell 9, the coolant will pass through the square notch 91 and the perforation 92, and enter between the inner hollow arc shell 9 and the round sleeve 61, and in the inner hollow After the coolant between the arc shell 9 and the round sleeve 61 is filled, the coolant will be blocked by the pressure arc surface 94 of the inner hollow arc shell 9. At this time, the exchange rate between the coolant in the inner hollow arc shell 9 and the round sleeve 61 and the external coolant will decrease. At this time, only the heat of the outer heat sink 62 will be greatly absorbed, and the overall heat dissipation efficiency is unified. When the temperature between the inner hollow arc shell 9 and the round sleeve 61 rises to the set value, the memory metal strip 10 is affected by the temperature and expands. The memory metal strip 10 will drive one end of the inner hollow arc shell 9 to move, and the other end of the inner hollow arc shell 9 is limited by the mounting shaft 8, so that the inner hollow arc shell 9 moves the mounting shaft 8 as a support. The inner hollow arc shell 9 is rotated at a certain point, so that one end of the top of the inner hollow arc shell 9 contacts the inside of the outer shell 3. At this time, the coolant cannot pass through the top of the inner hollow arc shell 9 in large quantities, and the bottom of the inner hollow arc shell 9 does not contact the circular sleeve 61 at this time, so that the pressure at this position is relieved, and the coolant will pass through between the inner hollow arc shell 9 and the circular sleeve 61 in large quantities, thereby absorbing the heat of the surface of the circular sleeve 61 and the lower half of the outer heat sink 62. At the same time, the coolant will pass through the inner heat sink 63, thereby absorbing the heat of the inner heat sink 63, and then pass through the square notch 91 to reach the right half shell 4, thereby increasing the circulation of this part of the coolant, and at the same time contacting the circular sleeve 61 and the outer heat sink The sheet 62 and the inner heat sink 63 absorb the heat of multiple components and enhance the heat dissipation effect. When the half-disk block 73 rotates with the thin-film turbine 72, due to the rotation of the inner hollow arc shell 9, the half-disk block 73 will squeeze the compressed arc surface 94 of the inner hollow arc shell 9, so that the inner hollow arc shell 9 rotates and returns to contact the surface of the circular sleeve 61. When the inner hollow arc shell 9 rotates, the inner hollow arc shell 9 will squeeze the memory metal strip 10, so that the memory metal strip 10 bends. When the heat is high again, the memory metal strip 10 will extend again to drive the inner hollow arc shell 9, and then repeat this action subsequently to continuously switch the heat dissipation efficiency.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
