Description

Technical Field

[0001] The invention belongs to the technical field of pump bodies, and in particular relates to a pump body heat dissipation and voltage stabilization mechanism. Background Art

[0002] In the field of modern industry and machinery, the pump body plays a core role in power transmission and fluid control. The stability and durability of its performance have a decisive impact on the operating efficiency and safety of the entire system. However, with the continuous advancement of industrial technology, the operating environment and working conditions faced by the pump body are becoming increasingly complex and changeable. Especially in the case of long-term high-load operation, the pump body will generate a lot of heat energy. If this heat cannot be dissipated in time and effectively, the temperature of the pump body will rise sharply, which will affect the working efficiency and service life, and in severe cases may even cause major safety failures.

[0003] Traditional pump cooling methods, such as finned or flat radiators, are limited by their geometric shapes, resulting in a poor match between the cooling area and fluid mechanics. Under high power density conditions, these radiators often have difficulty coping with heat accumulation, which can cause material fatigue and other failures. At the same time, traditional liquid cooling systems rely too much on a single working fluid cycle, which makes it difficult for them to adapt to sudden changes in working conditions, such as start-stop shocks and transient overloads, which in turn leads to thermal stress concentration, posing a threat to equipment safety.

[0004] In addition, the pump body also needs to face mechanical challenges such as vibration and impact during operation. Currently, the pump body is usually supported by ordinary bolt connections or cast iron brackets. This connection method not only has an unreasonable design of the heat conduction path, but also has a low thermal conductivity, which causes the heat generated by the bearing seat to be unable to be quickly transferred to the heat dissipation system. These external factors will not only have an adverse effect on the stable operation of the pump body, but may also cause further damage to the heat dissipation system, thereby exacerbating the heat load problem of the pump body. Summary of the invention

[0044] The embodiment of the present invention provides a pump heat dissipation and voltage stabilization mechanism, such as Figure 1-8 As shown, it includes a fractal honeycomb heat dissipation substrate 1, on which a pump body 2 is arranged;

[0045] The fractal honeycomb heat dissipation substrate 1 includes a three-dimensional layered fractal structure, including a main honeycomb layer 3, secondary branches 4 and terminal micropores 5. The main honeycomb layer 3 has a side length of 10 mm, the secondary branches 4 have a side length of 3 mm, and the terminal micropores 5 have a pore diameter of ≤0.5 mm.

[0046] The outer wall of the pump body 2 is provided with a composite cooling ring 6, and the cooling ring 6 is arranged around the middle section of the pump body 2;

[0047] Wherein, the cooling ring 6 comprises:

[0048] The annular liquid cooling channel 7 is sleeved in the spiral groove of the outer wall of the pump body 2. The inner cavity of the liquid cooling channel 7 circulates deionized water through the micro-turbine pump 8. The outer side of the liquid cooling channel 7 is integrated with a paraffin-based composite working fluid heat storage unit 9. The paraffin-based composite working fluid heat storage unit 9 is connected to the terminal micropores 5 of the fractal honeycomb heat dissipation substrate 1 through a capillary 10;

[0049] The phase change energy storage module 11 integrates a paraffin-based composite working fluid heat storage unit 9 outside the liquid cooling channel 7 and is connected to the terminal micropores 5 of the fractal honeycomb heat dissipation substrate 1 through the capillary 10;

[0050] Heat exchange enhancement structure, the inner wall of the liquid cooling channel 7 is sprayed with a graphene coating, and the outer wall is sprayed with a micro-arc oxidation ceramic layer.

[0051] It should be noted that the existing heat dissipation method of the pump body 2 is difficult to cope with the heat accumulation under high power density conditions, which is easy to cause material fatigue and other faults. At the same time, the liquid cooling system relies on a single working fluid cycle and is difficult to adapt to sudden changes in working conditions. In addition, the pump body 2 has a low thermal conductivity, poor heat transfer, and is easily affected by vibration and impact, which aggravates the heat load problem and affects the stable operation of the pump body 2. This solution adopts the design of a fractal honeycomb heat dissipation substrate 1 and a composite cooling ring 6, which greatly increases the heat dissipation area and combines a variety of high-efficiency heat dissipation technologies to ensure that the pump body 2 can still maintain a low temperature during long-term high-load operation, thereby extending the service life of the equipment; at the same time, the main shaft 13 and the bearing seat 12 are closely connected to the heat dissipation substrate through a high thermal conductivity copper column 14, forming an optimized heat conduction path, and with the help of the phase change energy storage module 11, the system's energy storage and heat load balance capabilities are enhanced, further improving the overall energy efficiency;

[0052] In addition, the combination of the rectangular bearing cavity and the three-level shock-absorbing and buffering system provides stable support and effective shock-absorbing effect for the pump body 2, protects key components from damage, and ensures the smooth operation of the system and the stability of heat dissipation efficiency; more importantly, by integrating multiple intelligent sensors and intelligent temperature-sensitive color-changing coatings, a comprehensive intelligent early warning system is constructed, which can monitor and warn potential faults in real time, thereby ensuring the safe and stable operation of the pump body 2.

[0053] Specifically, in this embodiment, this scheme mainly includes a fractal honeycomb heat dissipation substrate 1, on which a pump body 2 is arranged; the heat energy generated by the operation of the pump body 2 is transferred to the fractal honeycomb heat dissipation substrate 1 through the connected components, and the fractal honeycomb heat dissipation substrate 1 adopts a three-dimensional layered fractal structure design, including a main honeycomb layer 3, a secondary branch 4 and a terminal micropore 5; the side length of the main honeycomb layer 3 is 10mm, and the heat is quickly conducted away through a large-area fin structure. The side length of the secondary branch 4 is 3mm, which further refines the heat flow path and reduces the local thermal resistance; and the aperture of the terminal micropore 5 is less than or equal to 0.5mm, and the paraffin-based composite working fluid heat storage unit 9 is connected through a capillary 10 network to realize the gradient storage and release of heat; this design greatly increases the heat dissipation area and improves the heat dissipation efficiency;

[0054] The pump body 2 is mounted on a fractal honeycomb heat dissipation substrate 1, and a composite cooling ring 6 is provided on its outer wall; the cooling ring 6 is arranged around the middle section of the pump body 2, and mainly includes an annular liquid cooling channel 7, a phase change energy storage module 11 and a heat exchange enhancement structure;

[0055] The annular liquid cooling channel 7 is sleeved on the spiral groove of the outer wall of the pump body 2. The inner cavity of the liquid cooling channel 7 circulates deionized water through the micro-turbine pump 8 to effectively take away the heat generated by the pump body 2. The outer side of the liquid cooling channel 7 is also integrated with a paraffin-based composite working fluid heat storage unit 9. The paraffin-based composite working fluid heat storage unit 9 is connected to the terminal micropores 5 of the fractal honeycomb heat dissipation substrate 1 through a capillary 10, forming an efficient heat conduction network.

[0056] The phase change energy storage module 11 utilizes the characteristics of the paraffin-based composite working fluid absorbing and releasing heat during the phase change process, further improving the energy storage and heat dissipation capacity of the heat dissipation system; when the heat generated by the pump body 2 is transferred to the liquid cooling channel 7, part of the heat will be absorbed and stored by the paraffin-based composite working fluid, and then transferred to the fractal honeycomb heat dissipation substrate 1 through the capillary 10 for heat dissipation when needed;

[0057] The heat exchange enhancement structure further improves the heat dissipation effect of the liquid cooling channel 7; the inner wall of the liquid cooling channel 7 is sprayed with a graphene coating, which has excellent thermal conductivity and can quickly transfer heat from the pump body 2 to the deionized water, thereby accelerating the heat exchange between the liquid cooling medium and the pump body 2; while the outer wall is sprayed with a micro-arc oxidation ceramic layer, which inhibits the backflow of heat from the external environment and maintains low-temperature boundary conditions.

[0058] In a further preferred embodiment of the present invention, Figure 5 As shown, a pump cover 26 is provided at one end of the pump body, a bearing seat 12 is provided on the side of the pump body 2 away from the pump cover 26, a main shaft 13 is connected between the pump body 2 and the bearing seat 12, and the bearing seat 12 is fixed to the four-corner annular area of ​​the fractal honeycomb heat dissipation substrate 1 through high thermal conductivity copper columns 14. The copper columns penetrate the honeycomb heat dissipation substrate and contact the main shaft 13.

[0059] In this embodiment, the main shaft 13 is an axial power transmission path connecting the pump body 2 and the bearing seat 12, and also plays a role in heat conduction. In order to optimize the heat conduction path, the bearing seat 12 is firmly fixed in the four-corner annular area of ​​the fractal honeycomb heat dissipation substrate 1 through high thermal conductivity copper columns 14. The bearing seat 12 not only transmits the radial load during the rotation of the pump body 2 to ensure its temperature operation, but also the heat generated when the bearing seat 12 is running will also be transferred to the high thermal conductivity copper columns 14 through the main shaft 13. The high thermal conductivity copper columns 14 quickly conduct the heat to the fractal honeycomb heat dissipation substrate 1 for efficient heat dissipation.

[0060] In a further preferred embodiment of the present invention, Figure 5 As shown, it includes a modular shock-absorbing seat 15, and the modular shock-absorbing seat 15 includes:

[0061] A set of titanium alloy shock-absorbing bottom plates 16 arranged in parallel, two shock-absorbing bottom plates 16 are connected by high-strength bolts 17 to form a rectangular bearing cavity;

[0062] The four corners of the rectangular bearing cavity are respectively nested with a return spring 18 and a magnetorheological damper;

[0063] The shock-absorbing bottom plate 16 is connected to the bottom of the honeycomb heat dissipation substrate through a conical rubber bushing 19 to form a three-level shock-absorbing buffer system.

[0064] In this embodiment, the rectangular bearing cavity ensures the stable support of the pump body 2. The reset spring 18 and the magnetorheological damper are respectively nested at the four corners of the rectangular bearing cavity. The reset spring 18 can provide preliminary buffering and reset functions when the pump body 2 and the bearing seat 12 are impacted or vibrated, effectively reducing the impact of vibration on the system, and the magnetorheological damper can adjust its damping force in real time according to the size and frequency of the vibration, thereby realizing precise control of the vibration; in order to further enhance the shock absorption effect, the shock absorption base plate 16 is flexibly connected to the bottom of the honeycomb heat dissipation substrate through a conical rubber bushing 19. The rubber bushing 19 not only has good elasticity and wear resistance, but also can provide additional buffering and shock absorption during the vibration process. In this way, a three-stage shock absorption and buffering system composed of the reset spring 18, the magnetorheological damper and the conical rubber bushing 19 is formed. When the pump body 2 and the bearing seat 12 are subjected to external force, they can respond quickly, effectively absorb and disperse the vibration energy, and ensure the smooth operation of the pump body 2 and the stability of the heat dissipation efficiency.

[0065] In a further preferred embodiment of the present invention, Figure 5-6 As shown, it includes a distributed sensor assembly; the distributed sensor assembly includes:

[0066] FBG fiber Bragg grating 20, the FBG fiber Bragg grating 20 is axially distributed along the main axis 13;

[0067] A piezoelectric acoustic emission sensor 21 is embedded in the inner ring raceway surface of the bearing seat 12;

[0068] The signal transfer module 22 is integrated in the pump cover 26 and is connected to the FBG fiber Bragg grating 20 and the piezoelectric acoustic emission sensor 21 for signal connection.

[0069] In this embodiment, the FBG fiber Bragg grating 20 is distributed along the axial direction of the main shaft 13, so that the FBG fiber Bragg grating 20 can keenly capture the strain and temperature changes generated by the main shaft 13 during operation, thereby reflecting the working status of the pump body 2 in real time. Secondly, the piezoelectric acoustic emission sensor 21 is embedded in the raceway surface of the inner ring of the bearing seat 12, and can accurately capture the tiny vibrations and acoustic emission signals generated by the bearing seat 12 during operation; in order to efficiently collect and process these signals from different sensors, the signal adapter module 22 is integrated into the pump cover 26, and a stable signal connection is established between the signal adapter module 22 and the FBG fiber Bragg grating 20 and the piezoelectric acoustic emission sensor 21, ensuring that all key data can be transmitted accurately and timely.

[0070] In a further preferred embodiment of the present invention, Figure 1-8 As shown, the outer surface of the fractal honeycomb heat dissipation substrate 1 is coated with an oleophobic and hydrophobic coating.

[0071] In this embodiment, the oleophobic and hydrophobic coating utilizes physical properties such as surface tension and contact angle to inhibit the adhesion and diffusion of liquid on the surface of the fractal honeycomb heat dissipation substrate 1. The clean heat dissipation surface can more effectively transfer heat to the surrounding environment, avoiding the degradation of heat dissipation performance due to dirt accumulation.

[0072] In a further preferred embodiment of the present invention, Figure 5 As shown, a fiber grating sensor 23 is integrated in the rubber bushing 19 .

[0073] In this embodiment, the fiber grating sensor 23 changes with the deformation of the rubber bushing 19 , thereby reflecting the changes in physical quantities such as pressure and strain borne by the rubber bushing 19 .

[0074] In a further preferred embodiment of the present invention, Figure 1-8 As shown, the outer surface of the cooling ring 6 is coated with an intelligent temperature-sensitive color-changing coating.

[0075] In this embodiment, the change in coating color can directly reflect the temperature state of the cooling ring 6, allowing the operator to judge the temperature state of the cooling ring 6 by observing the color change of the coating. This intuitive monitoring method helps to detect temperature anomalies in time and take corresponding measures.

[0076] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the outer wall of the cooling ring 6 integrates a multi-mode temperature monitoring assembly, including:

[0077] An array of MEMS thermopiles 24 is attached to the surface of the liquid cooling channel 7;

[0078] The K-type thermocouple probe 25 is arranged at the corner of the liquid cooling channel 7 .

[0079] In this embodiment, the MEMS thermopile 24 array and the K-type thermocouple probe 25 respectively measure the temperature of the surface and corners of the liquid cooling channel 7, and convert the temperature information into electrical signal output. By collecting and processing these electrical signals, the temperature changes in the liquid cooling channel 7 can be monitored in real time.

[0080] Working principle: When the present invention is used, the heat energy generated by the pump body 2 during operation is transferred to the fractal honeycomb heat dissipation substrate 1 through the components closely connected thereto; the fractal honeycomb heat dissipation substrate 1 adopts a three-dimensional layered fractal structure design, specifically including a main honeycomb layer 3, a secondary branch 4 and a terminal micropore 5; the side length of the main honeycomb layer 3 is designed to be 10 mm, and the heat is quickly conducted away by a large-area fin structure; the side length of the secondary branch 4 is 3 mm, which further refines the heat flow path and effectively reduces the local thermal resistance; and the aperture of the terminal micropore 5 is less than or equal to 0.5 mm, and these micropores are connected to the paraffin-based composite working fluid heat storage unit 9 through a precise capillary 10 network, realizing the gradient storage and release of heat; this design greatly increases the heat dissipation area and significantly improves the heat dissipation efficiency;

[0084] The main shaft 13 serves as an axial power transmission path connecting the pump body 2 and the bearing seat 12. In order to optimize the heat conduction path, the bearing seat 12 is firmly fixed to the four-corner annular area of ​​the fractal honeycomb heat dissipation substrate 1 through the high thermal conductivity copper pillars 14; the bearing seat 12 not only transmits the radial load when the pump body 2 rotates to ensure its stable operation, but also the heat generated when the bearing seat 12 is running will be quickly transferred to the high thermal conductivity copper pillars 14 through the main shaft 13, and the high thermal conductivity copper pillars 14 will then quickly conduct the heat to the fractal honeycomb heat dissipation substrate 1 for efficient heat dissipation;

[0085] The rectangular bearing cavity provides a stable support for the pump body 2; the reset spring 18 and the magnetorheological damper are nested at the four corners of the bearing cavity respectively; the reset spring 18 can provide preliminary buffering and reset functions when the pump body 2 and the bearing seat 12 are impacted or vibrated, effectively reducing the impact of vibration on the system; and the magnetorheological damper can adjust its damping force in real time according to the size and frequency of the vibration, so as to achieve precise control of the vibration; in order to further enhance the shock absorption effect, the shock absorption base plate 16 is flexibly connected to the bottom of the fractal honeycomb heat dissipation substrate 1 through the conical rubber bushing 19; the rubber bushing 19 not only has good elasticity and wear resistance, but also can provide additional buffering and shock absorption during the vibration process; in this way, a three-stage shock absorption and buffering system composed of the reset spring 18, the magnetorheological damper and the conical rubber bushing 19 is formed, which ensures that the pump body 2 can respond quickly when subjected to external force, effectively absorbs and disperses vibration energy, and maintains the smooth operation of the pump body 2 and the stability of the heat dissipation efficiency;

[0086] In order to monitor the working state of the pump body 2 in real time, the FBG fiber Bragg grating 20 is distributed along the axial direction of the main shaft 13; the FBG fiber Bragg grating 20 can keenly capture the strain and temperature changes generated by the main shaft 13 during operation, thereby reflecting the working state of the pump body 2 in real time; in addition, the piezoelectric acoustic emission sensor 21 is embedded in the raceway surface of the inner ring of the bearing seat 12, which can accurately capture the tiny vibration and acoustic emission signals generated by the bearing during operation; in order to efficiently collect and process these signals from different sensors, the signal adapter module 22 is integrated inside the pump cover 26; a signal connection is established between the signal adapter module 22 and the FBG fiber Bragg grating 20 and the piezoelectric acoustic emission sensor 21 to ensure that all key data can be transmitted accurately and timely;

[0087] The outer surface of the fractal honeycomb heat dissipation substrate 1 is coated with an oleophobic and hydrophobic coating; the oleophobic and hydrophobic coating utilizes physical properties such as surface tension and contact angle to effectively inhibit the adhesion and diffusion of liquid on the surface of the heat dissipation substrate; the clean heat dissipation surface can more efficiently transfer heat to the surrounding environment, avoiding the degradation of heat dissipation performance caused by dirt accumulation;

[0088] In addition, the fiber grating sensor 23 will also change with the deformation of the rubber bushing 19, thereby accurately reflecting the changes in the physical quantity borne by the rubber bushing 19; at the same time, the intelligent temperature-sensitive color-changing coating coated on the outer wall of the cooling ring 6 can intuitively reflect the temperature state of the cooling ring 6 through its color change; the operator can easily judge the temperature state of the cooling ring 6 by simply observing the color change of the coating; this intuitive monitoring method helps to detect temperature anomalies in a timely manner, so as to quickly take corresponding measures;

[0089] Finally, in order to monitor the temperature changes in the liquid cooling channel 7 in real time, the MEMS thermopile 24 array and the K-type thermocouple probe 25 are arranged on the surface and corners of the liquid cooling channel 7; these sensors can accurately measure the temperature and convert the temperature information into electrical signal output; by collecting and processing these electrical signals, real-time monitoring of the temperature changes in the liquid cooling channel 7 can be achieved, providing a strong guarantee for the stable operation of the system.
