[0033] During condenser operation, the liquid's subcooling (the difference between the liquid temperature and its saturation temperature) is significantly negatively correlated with the dissolved oxygen content. The presence of dissolved oxygen reduces the liquid's heat transfer efficiency, affecting the stability of the condenser's subcooling. To reduce oxygen levels, existing technologies primarily employ physical deoxygenation methods (such as bubbling deoxygenation). However, traditional bubbling deoxygenation produces a high level of steam condensation noise, leading to excessive condenser vibration and noise, impacting the user experience.

[0034] The present application aims to solve at least one of the technical problems existing in the related art. To this end, the present application proposes a deoxygenation device 50 applied to a condenser, which is used to reduce the oxygen content of the liquid in the condenser, thereby optimizing the stability of the subcooling and improving the user experience.

[0035] The following combination Figures 1-9The deoxidizer 50 applied to a condenser (hereinafter referred to as the deoxidizer 50 ) and the low-noise hybrid condenser of the present invention are described.

[0036] According to the deoxidation device 50 proposed in this application example, please refer to Figures 1 to 3 , including an outer layer component 100 and an inner layer component 200, the outer layer component 100 is hollow inside; the inner layer component 200 is arranged inside the outer layer component 100, and a steam mainstream channel 101 is formed between the inner layer component 200 and the outer layer component 100, a deoxygenation liquid chamber 201 is provided inside the inner layer component 200, and the inner layer component 200 is provided with a steam diversion channel 210 and an immersion channel 220, the steam diversion channel 210 connects the steam mainstream channel 101 and the deoxygenation liquid chamber 201, and the immersion channel 220 connects the deoxygenation liquid chamber 201.

[0037] According to the deoxygenation device 50 of the embodiment of the present application, the liquid in the deoxygenation liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for inter-wall heat exchange with the steam in the steam diversion channel 210, reducing direct contact between steam and water, thereby reducing the bubbling deoxygenation noise to a certain extent.

[0038] It is understood that the outer component 100 is the outer structure of the deoxygenation device 50, and the inner component 200 is arranged inside the outer component 100. It cooperates with the outer component 100 to form a steam main channel 101 between the two. The steam main channel 101 is the main path for steam flow, allowing steam to circulate quickly and smoothly. At the same time, a deoxygenation liquid chamber 201 is provided inside the inner component 200. The liquid in the deoxygenation liquid chamber 201 can enter the immersion channel 220 and perform a wall-to-wall heat exchange with the steam in the steam diversion channel 210. The steam diversion channel 210 connects the steam main channel 101 and the deoxygenation liquid chamber 201. Its function is to reasonably divert the steam in the steam main channel 101 to the deoxygenation liquid chamber 201, and to perform steam bubbling heating on the liquid.

[0039] The deoxygenation device 50 of the present application reduces direct contact between steam and water, thus avoiding the generation of large bubbles and violent physical collisions caused by steam directly impacting the liquid, thereby reducing noise generated during the bubbling deoxygenation process to a certain extent. Conventional bubbling deoxygenation methods, where steam and water directly contact each other, generate large bubbles when the steam impacts the liquid, and the bursting of these bubbles produces a loud noise. However, the device utilizes partition-type heat exchange, which reduces this occurrence and thus reduces noise.

[0040] It is understood that the liquid in the deoxygenation liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for inter-wall heat exchange with the steam in the steam diversion channel 210. The liquid in the immersion channel 220 can absorb the heat of the steam in the steam diversion channel 210, thereby achieving an increase in the liquid temperature gradient. This process effectively reduces the superheat difference between the steam and the liquid in the deoxygenation liquid chamber 201. Most of the steam completes the condensation process inside the steam diversion channel 210, and at least part of the steam completes the gas-liquid phase transition within the steam diversion channel 210, avoiding direct impact between the steam and the liquid in the deoxygenation liquid chamber. This significantly reduces the noise source caused by bubble collapse due to rapid condensation when the steam directly contacts the liquid. The porous structure provided in the steam diversion channel 210 (the several branch pipes mentioned later) can enhance the dispersed condensation of steam, reduce the collapse intensity of bubbles formed by steam condensation, and can also absorb noise energy through the pore damping effect of the porous structure. The residual bubble collapse sound wave undergoes multiple reflections and attenuation in the tortuous path of the channel, achieving multi-dimensional noise reduction.

[0041] According to one embodiment of the present application, each steam diversion channel 210 includes a mainstream pipe 211 and several branch pipes 212. The mainstream pipe 211 is provided with a steam inlet 213, and the steam inlet 213 is connected to the steam mainstream channel 101. The branch pipe 212 is connected to the mainstream pipe 211. The branch pipe 212 is provided with a steam outlet 214, and the steam outlet 214 is connected to the deoxygenation liquid chamber 201.

[0042] By providing a main flow pipe 211 and a plurality of branch pipes 212, steam can flow from the main steam channel 101 through the main flow pipe 211 and then through the multiple branch pipes 212 into the deoxygenation liquid chamber 201. The multiple branch pipes 212 increase the contact area between the steam and the liquid in the deoxygenation liquid chamber 201, allowing for more efficient heat exchange between the steam and the liquid. Furthermore, the multiple branch pipes 212 increase the steam flow path, enhancing heat exchange between the steam diversion channel 210 and the immersion channel 220.

[0043] It should be noted that Figure 2 yes Figure 1 A schematic diagram of a cross-sectional structure in the first direction at AA provided in an embodiment. Figure 3 yes Figure 1 The embodiment provides a schematic diagram of a cross-sectional structure in the second direction at AA, wherein the first direction and the second direction are opposite.

[0044] According to one embodiment of the present application, the area of the steam inlet 213 of each steam diversion channel 210 is greater than or equal to the sum of the areas of the plurality of steam outlets 214 .

[0045] According to one embodiment of the present application, the tributary pipeline 212 includes N-stage tributary pipelines (N≥2), wherein: The first-stage branch pipe is connected to the main pipe 211, and a steam inlet 213 is provided at the starting end of the first-stage branch pipe; The k-th branch pipe (2≤k≤N) branches off and extends from the previous branch pipe 212; The N-th stage branch pipe is connected to the deoxygenation liquid chamber 201 , and a steam outlet 214 is provided at the end of the N-th stage branch pipe.

[0046] In an embodiment of the present application, the branch pipes 212 are divided according to a certain hierarchical relationship, and there are at least 2 levels. Each level of branch pipes 212 undertakes different tasks in the process of transporting and distributing steam, and a more refined distribution of steam is achieved through a multi-stage setting. The first-level branch pipe is directly connected to the main pipe 211, and is the starting level for steam to enter the branch pipe 212 system from the main pipe 211. Starting from the first level, each level of branch pipes 212 is forked and extended from the previous level of branch pipes 212. This bifurcated extension method allows the steam to be continuously subdivided, increases the contact area between the steam and the liquid in the deoxygenation liquid chamber 201, and improves the heat exchange efficiency. The Nth level branch pipe is the last level of the branch pipe 212 system. It is directly connected to the deoxygenation liquid chamber 201, and a steam outlet 214 is provided at its end.

[0047] The multi-stage branch pipes 212 increase the contact area between the steam and the liquid in the deoxygenation chamber 201. As the steam passes through each stage of the branch pipes 212, it exchanges heat with the surrounding liquid. As the steam continues to branch and extend, more liquid comes into contact with the steam, accelerating the heat transfer rate, allowing the liquid to reach the required deoxygenation temperature more quickly, thereby improving heat exchange efficiency.

[0048] In one embodiment, please refer to Figure 2 The branch pipe 212 is a secondary branch pipe, which has a first-level branch pipe and a second-level branch pipe.

[0049] According to one embodiment of the present application, each immersion channel 220 is provided with at least two liquid inlets 221. The liquid inlets 221 are the entry points for liquid into the immersion channel 220. Providing at least two liquid inlets 221 allows liquid to enter the immersion channel 220 from multiple different locations. The distribution of the liquid inlets 221 at different locations allows liquid to enter the deoxygenation liquid chamber 201 more evenly and fill the channel space.

[0050] According to one embodiment of the present application, a plurality of steam diversion channels 210 are distributed along the circumference of the inner component 200 , and / or the immersion flow channels 220 are distributed along the circumference of the inner component 200 .

[0051] When the plurality of steam diversion channels 210 are distributed along the circumference of the inner component 200 and / or the immersion flow channels 220 are distributed along the circumference of the inner component 200, uniform distribution of steam and liquid within the device can be achieved. This uniform distribution allows the steam and liquid to more fully contact other components or media within the device, thereby improving heat exchange efficiency.

[0052] According to one embodiment of the present application, the inner layer component 200 is provided with a plurality of steam diversion channels 210 and immersion channels 220 along its longitudinal extension direction, wherein the steam diversion channels 210 and the immersion channels 220 are arranged alternately and spaced apart, and adjacent immersion channels 220 are connected to each other through transverse connecting channels 230.

[0053] The inner component 200 is provided with multiple steam diversion channels 210 and immersion channels 220 along its longitudinal extension, arranged in alternating intervals. This layout ensures uniform distribution of steam and liquid within the device. Adjacent immersion channels 220 are interconnected via transverse connecting channels 230, further promoting fluid mixing and flow. When steam enters the device through the steam diversion channels 210, it fully engages with the liquid in each immersion channel 220 through inter-wall heat exchange, achieving efficient heat exchange.

[0054] According to one embodiment of the present application, the main steam channel 101 is an annular channel.

[0055] The structure of the annular channel allows the steam to be evenly distributed along the annular path when flowing within the channel. Due to the symmetry of the annular channel, the flow resistance of the steam in all directions is relatively balanced, so that the steam can enter the deoxidation liquid chamber 201 more evenly through the steam diversion channel 210.

[0056] According to one embodiment of the present application, the deoxygenation device 50 includes a check mechanism, which is provided on the steam diversion channel 210. The check mechanism is configured as follows: when the fluid pressure in the steam main channel 101 is greater than that in the steam diversion channel 210, the fluid is allowed to flow unidirectionally from the steam main channel 101 to the steam diversion channel 210; when the fluid pressure in the steam diversion channel 210 is greater than that in the steam main channel 101, the reverse flow of the fluid from the steam diversion channel 210 to the steam main channel 101 is blocked.

[0057] It is understandable that by setting up a check mechanism, the liquid can be prevented from flowing back into the steam mainstream channel 101. When the steam enters the steam mainstream channel 101, the steam will not directly contact the liquid in the steam mainstream channel 101, thereby avoiding the direct generation of noise.

[0058] According to one embodiment of the present application, the check mechanism is implemented using a check valve structure, and the opening and closing direction of the valve core of the check valve is consistent with the flow direction from the steam main channel 101 to the steam branch channel 210.

[0059] In one embodiment, the deoxygenation device 50 includes a second check mechanism, which can be set at the position of the steam outlet 214. The second check mechanism is configured as follows: when the fluid pressure in the steam diversion channel 210 is greater than that in the deoxygenation liquid chamber 201, the fluid is allowed to flow unidirectionally from the steam diversion channel 210 to the deoxygenation liquid chamber 201; when the fluid pressure in the deoxygenation liquid chamber 201 is greater than that in the steam diversion channel 210, the reverse flow of the fluid from the deoxygenation liquid chamber 201 to the steam diversion channel 210 is blocked.

[0060] It can be understood that the second check mechanism can prevent the liquid in the deoxygenation liquid chamber 201 from flowing back into the steam diversion channel 210. When the steam enters the steam main channel 101, the steam will not directly contact the liquid in the steam diversion channel 210, thereby avoiding the direct generation of noise.

[0061] According to one embodiment of the present application, the second check mechanism can be implemented by a diaphragm check valve, and the opening and closing direction of the valve core of the diaphragm check valve is consistent with the flow direction from the steam diversion channel 210 to the deoxygenation liquid chamber 201.

[0062] The deoxygenation device 50 of the present application is described below with reference to a specific embodiment. The deoxygenation device 50 can be divided into a two-layer annular structure (an outer layer component 100 and an inner layer component 200). The annular space between the outer layer component 100 and the inner layer component 200 serves as a mainstream steam channel 101 for bubbling. The inner layer component 200 is prepared by 3D printing. The inner layer component 200 has a tree-like fractal micro-channel structure (steam diversion channel 210) and an immersion channel 220. After the mainstream steam passes through the steam diversion channel 210, the deoxygenation steam can be evenly and finely ejected from the steam outlet 214 hole of the steam diversion channel 210, thereby heating the water in the central deoxygenation liquid chamber 201, causing the water to heat up, reducing the degree of supercooling, and thus reducing the oxygen content; the tree-like fractal micro-channel structure has low resistance, which can reduce the flow resistance of the steam; the steam diversion channel 210 is a circulation channel for the bubbling steam, and the immersion channel 220 is an immersion circulation channel for the fluid; In the steam diversion channel 210, steam enters the tree-like fractal micro-channel structure from the steam main channel 101 through the steam inlet 213, and then flows to the steam outlet 214, realizing bubbling deoxygenation on the steam side; while in the immersion channel 220, water in the deoxygenation liquid chamber 201 can enter the immersion channel 220 through the liquid inlet 221 formed by the fine holes of the inner layer component 200, and perform inter-wall heat exchange with the steam in the steam diversion channel 210 in the immersion channel 220, thereby improving the heating performance of the liquid and reducing the bubbling heating demand through direct contact between steam and water, thereby reducing the bubbling deoxygenation noise to a certain extent; two adjacent layers of immersion flow channels There are channels connecting them, and water can flow between different immersion flow channels; at the same time, due to the micro-channel porous structure of the inner layer component 200, it has the function of sound absorption and noise reduction. When the steam ejected from the steam outlet 214 of the inner layer component 200 is in direct contact with the water in the deoxygenation liquid chamber 201 for heat exchange, the vibration noise generated by the steam collapse will be greatly absorbed and weakened by the micro-channel porous structure of the inner layer component 200 in the process of propagating to the surrounding area, thereby achieving a good effect of noise reduction; in addition, since the bubbling steam condenses after contacting with water, and the water flows due to heat after being heated, it will automatically drive the water in the deoxygenation liquid chamber 201 to be discharged to the deaerator outlet.

[0063] According to the second aspect of the embodiment of the present application, a low-noise hybrid condenser includes a condenser shell 8 and the above-mentioned deoxygenation device 50, and a condensation chamber 2 is provided inside the condenser shell 8; the above-mentioned deoxygenation device 50 is provided in the condensation chamber 2, and the deoxygenation liquid chamber 201 is connected to the condensation chamber 2.

[0064] A condenser is a device used to cool gas or vapor and convert it into liquid. It is widely used in industrial production, energy conversion, and other fields. The condenser housing 8 is the outer structure of the condenser, providing protection and support for the internal components. It has a certain strength and sealing properties to contain and isolate the internal fluid. The deaerator 50 is used to remove dissolved oxygen from the fluid (such as water).

[0065] It is understandable that the liquid in the deoxygenation liquid chamber 201 can enter the immersion channel 220. The liquid entering the immersion channel 220 is suitable for inter-wall heat exchange with the steam in the steam diversion channel 210. The liquid in the immersion channel 220 can absorb the heat of the steam in the steam diversion channel 210, thereby achieving an increase in the liquid temperature gradient. This process effectively reduces the superheat difference between the steam and the liquid in the deoxygenation liquid chamber. Most of the steam completes the condensation process inside the steam diversion channel 210, and at least part of the steam completes the gas-liquid phase transition inside the steam diversion channel 210, avoiding direct impact between the steam and the liquid in the deoxygenation liquid chamber. This significantly reduces the noise source caused by bubble collapse due to rapid condensation when the steam directly contacts the liquid. The porous structure (several branch pipes) provided in the steam diversion channel 210 can enhance the dispersed condensation of steam, reduce the collapse intensity of bubbles formed by steam condensation, and can also absorb noise energy through the pore damping effect of the porous structure. The residual bubble collapse sound wave undergoes multiple reflections and attenuation in the tortuous path of the channel, achieving multi-dimensional noise reduction.

[0066] It should be noted that the low-noise hybrid condenser of the present application includes the above-mentioned deoxygenation device 50 and therefore has all the technical effects of the above-mentioned deoxygenation device 50 , which will not be described in detail here.

[0067] According to one embodiment of the present application, the low-noise hybrid condenser includes a porous grid rectifying structure 60 , which is disposed at the outlet of the deoxygenation liquid chamber 201 .

[0068] The porous grid rectifying structure 60 is a grid-like structure composed of a plurality of holes, which divides and guides the fluid through the holes and further absorbs excess noise energy through the porous structure.

[0069] According to the embodiment of the present application, a low-noise hybrid condenser is proposed. Figures 4 to 6 , comprising: a condenser housing 8, a water spray assembly 3, a vibration isolation structure 12, and a water spray plate 6. A condensation chamber 2 is provided within the condenser housing 8; the water spray assembly 3 is mounted within the condensation chamber 2 and is provided with a nozzle 5, which faces the inner wall of the condenser housing 8; the vibration isolation structure 12 is connected to at least one of the condenser housing 8 and the water spray assembly 3, and is provided with a vibration isolation magnetic member 13; the water spray plate 6 is connected to a matching magnetic member 14, and the vibration isolation magnetic member 13 and the matching magnetic member 14 magnetically repel each other. When the matching magnetic member 14 is inserted into the vibration isolation structure 12, the vibration isolation magnetic member 13 keeps the matching magnetic member 14 in a suspended state, and the water spray plate 6 and the vibration isolation structure 12 do not contact each other.

[0070] According to the low-noise hybrid condenser of the embodiment of the present application, the magnetic repulsion between the vibration isolation magnetic part 13 and the matching magnetic part 14 is used to prevent the water spray plate 6 and the condenser shell 8 from contacting each other, thereby effectively isolating the transmission path of the vibration energy of the water spray plate 6 to the condenser shell and reducing the noise generated by the spray liquid film 4 impacting the water spray plate 6 on the condenser.

[0071] The condenser housing 8 is the main structural part of the condenser. It provides a relatively closed space for the condensation process, namely the condensation chamber 2. The condensation chamber 2 is the place where the steam undergoes the condensation reaction. The water spray assembly 3 is installed in the condensation chamber 2, and can spray liquid (usually cooling water) onto the inner wall of the condenser housing 8 through the nozzle 5. The vibration isolation structure 12 is used to isolate the transmission of vibration energy of the water spray plate 6. Due to the principle of magnetic repulsion, the vibration isolation magnetic part 13 and the matching magnetic part 14 can be in a suspended state under the action of the vibration isolation magnetic part 13 after the matching magnetic part 14 is passed through the vibration isolation structure 12, thereby preventing the water spray plate 6 from contacting the vibration isolation structure 12.

[0072] During condenser operation, the impact of the spray liquid film 4 on the water spray plate 6 generates vibration and noise. By installing the vibration isolation structure 12 and utilizing the magnetic repulsion between the vibration isolation magnetic element 13 and the matching magnetic element 14, the water spray plate 6 is suspended and prevented from contacting the condenser housing 8. This effectively isolates the transmission path of the vibration energy of the water spray plate 6 to the condenser housing, significantly reducing the noise generated by the spray liquid film 4 impacting the water spray plate 6.

[0073] It will be appreciated that nozzle 5 can be carefully designed and arranged so that nozzle 5 is aligned with the inner wall of condenser housing 8. When cooling water passes through water spray assembly 3, it is ejected from nozzle 5 at a certain pressure and velocity, forming a uniform liquid film 4 in condensing chamber 2. This liquid film 4 effectively absorbs heat from condensing chamber 2 and promotes condensation of gas or steam.

[0074] In one embodiment, the water spray assembly 3 is disposed in the middle of the condensation chamber 2 , and the water spray assembly 3 can spray a liquid film 4 onto the inner walls of the condensation chamber 2 around it.

[0075] It should be noted that the water spray plate 6 and the vibration isolation structure 12 are neither in direct contact nor in indirect contact.

[0076] In one embodiment, the water spray plate 6 is provided with a plurality of through holes 7 .

[0077] In one embodiment, a steam inlet 1 is provided on the top of the condenser shell 8 , and a condensate outlet 9 is provided at the bottom of the condenser shell 8 .

[0078] In one embodiment, an air extraction device 11 is provided at the bottom of the water spray assembly 3 , and the air extraction device 11 is connected to a cooling water pipe 10 .

[0079] According to one embodiment of the present application, the liquid sprayed from the nozzle 5 is adapted to form a liquid film 4 within the condensing chamber 2. The vibration isolation structure 12 is positioned within the gaps in the liquid film 4. Specifically, after the liquid is sprayed from the nozzle 5, it rapidly expands within the condensing chamber 2 to form the liquid film 4. This liquid film 4 flows downward along the inner wall of the condenser under the influence of gravity and surface tension. Because the vibration isolation structure 12 is carefully positioned within the gaps in the liquid film 4, the liquid film 4 does not collide with the isolation structure 12 during its flow, instead smoothly falling onto the water spray plate 6.

[0080] The vibration isolation structure 12 is arranged in the gap of the liquid film 4 , which effectively avoids direct contact between the liquid film 4 and the vibration isolation structure 12 , thereby preventing the liquid film 4 from generating noise due to impacting the vibration isolation structure 12 .

[0081] According to one embodiment of the present application, the vibration isolation structure 12 includes a lower vibration isolation unit 15, the lower vibration isolation unit 15 includes a lower mounting plate 16 and a lower non-magnetic straight cylinder 17, the lower mounting plate 16 is connected to at least one of the condenser housing 8 and the water spray assembly 3, the lower non-magnetic straight cylinder 17 is connected to the lower mounting plate 16, a lower vibration isolation cavity 18 is provided inside the lower non-magnetic straight cylinder 17, a lower magnetic block 19 is provided on the inner wall of the lower vibration isolation cavity 18, a strong magnetic block 20 is provided at the bottom of the lower vibration isolation cavity 18, the lower part of the matching magnetic part 14 is passed through the lower vibration isolation cavity 18, and the magnetic poles of the lower part of the matching magnetic part 14 are the same as the magnetic poles of the lower magnetic block 19 and the strong magnetic block 20.

[0082] The lower portion of the matching magnetic element 14 passes through the lower vibration isolation cavity 18, and its lower magnetic poles are aligned with those of the lower magnetic block 19 and the strong magnetic block 20. Based on the principle of magnetism, like magnetic poles repel each other. The lower magnetic block 19 and the strong magnetic block 20 jointly exert an upward repulsive force on the matching magnetic element 14, allowing the spray plate 6 to stably levitate above the vibration isolation structure 12. This stable suspension effectively isolates the vibration energy of the spray plate 6 from being transferred to the condenser housing 8, significantly reducing the noise generated by the spray liquid film 4 impacting the spray plate 6.

[0083] The lower mounting plate 16 is connected to at least one of the condenser housing 8 and the water spray assembly 3. This connection method allows for flexibility in the installation position of the lower vibration isolation unit 15. An appropriate connection position can be selected based on actual needs to optimize the vibration isolation effect.

[0084] According to one embodiment of the present application, the lower non-magnetic straight cylinder 17 is one of a copper straight cylinder, a stainless steel straight cylinder, and a titanium alloy straight cylinder.

[0085] The lower non-magnetic straight tube 17 provides space for the matching magnetic member 14 to be installed and moved, while avoiding interference with the magnetic effect. The lower non-magnetic straight tube 17 is connected to the lower mounting plate 16. The connection method can be welding, bolting, etc. to ensure the firmness and stability of the connection.

[0086] The lower non-magnetic cylinder 17 houses a lower vibration isolation cavity 18. Lower magnetic blocks 19 are installed on the inner wall of the cavity, and a strong magnetic block 20 is located at the bottom of the cavity. Both lower magnetic blocks 19 and strong magnetic blocks 20 are made of high-performance magnetic materials with high magnetic strength. The lower magnetic blocks 19 are evenly distributed along the inner wall of the cavity 18, and together with the strong magnetic block 20, they form a strong magnetic repulsion field.

[0087] The lower portion of the matching magnetic element 14 is inserted into the lower vibration isolation cavity 18. The magnetic poles of the lower portion of the matching magnetic element 14 align with those of the lower magnetic block 19 and the strong magnetic block 20. When the matching magnetic element 14 is installed in the lower vibration isolation cavity 18, the lower magnetic block 19 and the strong magnetic block 20 exert an upward repulsive force on the matching magnetic element 14, causing the matching magnetic element 14 to suspend the water spray plate 6. At this point, the water spray plate 6 is not in contact with the vibration isolation structure 12, effectively isolating the water spray plate 6 from transmitting vibration energy to the condenser housing 8.

[0088] According to one embodiment of the present application, the lower magnetic block 19 is a lower annular magnetic block, and the lower portion of the matching magnetic member 14 is inserted into the inner hole of the annular magnetic block.

[0089] The lower annular magnetic block is an annular magnetic block, and its inner hole is a through-hole for matching the lower part of the magnetic member 14. The annular design makes the magnetic force distribution more uniform, which is conducive to generating a stable and effective magnetic repulsion force.

[0090] The lower portion of the matching magnetic element 14 is designed to match the inner hole of the lower annular magnet, allowing it to be smoothly inserted into the inner hole. When the matching magnetic element 14 is installed in the inner hole of the lower annular magnet, its lower magnetic poles align with those of the lower annular magnet and the strong magnetic element 20. According to the principle of magnetism, like magnetic poles repel each other. The lower annular magnet and the strong magnetic element 20 jointly generate an upward repulsive force on the matching magnetic element 14, causing the matching magnetic element 14 to cause the water spray plate 6 to remain suspended.

[0091] According to one embodiment of the present application, the vibration isolation structure 12 includes an upper vibration isolation unit 21, the upper vibration isolation unit 21 includes an upper mounting plate 22 and an upper non-magnetic straight cylinder 23, the upper mounting plate 22 is connected to at least one of the condenser housing 8 and the water spray assembly 3, the upper non-magnetic straight cylinder 23 is connected to the upper mounting plate 22, an upper vibration isolation cavity 24 is provided inside the upper non-magnetic straight cylinder 23, an upper magnetic block 25 is provided on the inner wall of the upper vibration isolation cavity 24, the upper part of the matching magnetic part 14 is passed through the upper vibration isolation cavity 24, and the magnetic pole of the upper part of the matching magnetic part 14 is the same as the magnetic pole of the upper magnetic block 25.

[0092] The upper portion of the matching magnetic element 14 is inserted into the upper vibration isolation cavity 24, and its upper magnetic poles are aligned with those of the upper magnetic block 25. Based on the principle of magnetism, like magnetic poles repel each other. The upper magnetic block 25 and the strong magnetic block 20 jointly exert an upward repulsive force on the matching magnetic element 14, allowing the spray plate 6 to stably suspend on the vibration isolation structure 12. This stable suspension effectively isolates the vibration energy of the spray plate 6 from being transferred to the condenser housing 8, significantly reducing the noise generated by the spray liquid film 4 impacting the spray plate 6.

[0093] The upper mounting plate 22 is connected to at least one of the condenser housing 8 and the water spray assembly 3. This connection method allows for flexibility in the installation position of the upper vibration isolation unit 21. An appropriate connection position can be selected based on actual needs to optimize the vibration isolation effect.

[0094] According to an embodiment of the present application, the upper non-magnetic straight cylinder 23 is one of a copper straight cylinder, a stainless steel straight cylinder, and a titanium alloy straight cylinder.

[0095] The upper non-magnetic straight tube 23 provides space for the matching magnetic member 14 to be installed and moved, while avoiding interference with the magnetic effect. The upper non-magnetic straight tube 23 is connected to the upper mounting plate 22. The connection method can be welding, bolting, etc. to ensure the firmness and stability of the connection.

[0096] An upper vibration isolation chamber 24 is located within the upper non-magnetic cylinder 23. Upper magnetic blocks 25 are installed on the inner wall of the upper vibration isolation chamber 24, and a strong magnetic block 20 is installed at the bottom of the upper vibration isolation chamber 24. Both upper magnetic blocks 25 and strong magnetic block 20 are made of high-performance magnetic materials with high magnetic strength. The upper magnetic blocks 25 are evenly distributed along the inner wall of the upper vibration isolation chamber 24, and together with the strong magnetic block 20, they form a strong magnetic repulsive field.

[0097] The upper portion of the matching magnetic element 14 is inserted into the upper vibration isolation cavity 24. The magnetic poles of the upper portion of the matching magnetic element 14 are aligned with those of the upper magnetic block 25 and the strong magnetic block 20. When the matching magnetic element 14 is installed in the upper vibration isolation cavity 24, the upper magnetic block 25 and the strong magnetic block 20 exert an upward repulsive force on the matching magnetic element 14, causing the matching magnetic element 14 to suspend the water spray plate 6. At this point, the water spray plate 6 is not in contact with the vibration isolation structure 12, effectively isolating the water spray plate 6 from transmitting vibration energy to the condenser housing 8.

[0098] According to one embodiment of the present application, the upper magnetic block 25 is an upper annular magnetic block, and the upper portion of the matching magnetic member 14 is inserted into the inner hole of the annular magnetic block.

[0099] The upper annular magnetic block is an annular magnetic block, and its inner hole is a through-hole for matching the upper part of the magnetic member 14. The annular design makes the magnetic force distribution more uniform, which is conducive to generating a stable and effective magnetic repulsion force.

[0100] The upper portion of the matching magnetic element 14 is designed to match the inner hole of the upper annular magnet, allowing it to be smoothly inserted into the inner hole. When the matching magnetic element 14 is installed in the inner hole of the upper annular magnet, its upper magnetic poles align with those of the upper annular magnet and the strong magnetic element 20. According to the principle of magnetism, like magnetic poles repel each other. The upper annular magnet and the strong magnetic element 20 jointly generate an upward repulsive force on the matching magnetic element 14, causing the matching magnetic element 14 to cause the water spray plate 6 to remain suspended.

[0101] According to one embodiment of the present application, there are two vibration isolation structures 12, one of which is provided on the condenser housing 8, and the other is provided on the water spray assembly 3, and matching magnetic parts 14 are provided on both sides of the water spray plate 6 corresponding to the vibration isolation structure 12.

[0102] The condenser housing 8 is the core part of the condenser, and its own vibration and external vibration may affect the water spraying plate 6. By arranging the vibration isolation structure 12 on the condenser housing 8, these vibration energies can be effectively prevented from being transmitted to the water spraying plate 6.

[0103] Another vibration isolation structure 12 is provided on the water spray assembly 3. During operation, the water spray assembly 3 generates certain vibrations due to the spraying and flow of liquid. These vibrations may be transmitted to the water spray plate 6 through connecting components, affecting the stability of the liquid film 4 and the condensation effect. By providing the vibration isolation structure 12 on the water spray assembly 3, these vibrations can be effectively isolated, ensuring the normal operation of the water spray plate 6. The design of the vibration isolation structure 12 provided on the water spray assembly 3 is similar to that provided on the condenser housing 8, but can be appropriately adjusted and optimized based on the specific structure and characteristics of the water spray assembly 3.

[0104] Matching magnetic elements 14 are positioned on either side of the water spray plate 6, corresponding to the vibration isolation structure 12. This symmetrical arrangement ensures that the water spray plate 6 is subjected to uniform magnetic repulsion in both directions, thereby maintaining a stable suspension. When the condenser is operating, the water spray assembly 3 sprays liquid into the condenser, forming a liquid film 4. This liquid film 4 vibrates when it strikes the water spray plate 6. However, due to the interaction between the matching magnetic elements 14 and the vibration isolation structure 12, the water spray plate 6 does not transfer this vibration energy to the condenser housing 8 or the water spray assembly 3. Instead, it remains in a stable suspension, effectively reducing noise generation.

[0105] The dual vibration isolation structure 12 in this embodiment provides an effective solution for condenser vibration isolation. By providing the isolation structures 12 on the condenser housing 8 and the water spray assembly 3, and employing symmetrically arranged matching magnetic components 14, all-around vibration isolation is achieved for the water spray plate 6, improving the condenser's performance and reliability while reducing noise.

[0106] According to one embodiment of the present application, the water spray assembly 3 includes an air suction device 11 and a water spray body. The water spray body is provided with a nozzle 5. The outer shell and inner wall of the air suction device 11 are parallel.

[0107] The suction device 11 provides the necessary conditions for the water spraying process by generating negative pressure and other methods. The water spraying body is the core part of the water spraying assembly 3. It contains the channels and devices for storing liquid, transporting liquid, and controlling liquid spraying. The nozzle 5 is installed on the water spraying body.

[0108] The low-noise hybrid condenser of the present application is described below with reference to a specific embodiment.

[0109] First, the mixing condenser water spray plate 6 is connected to the condenser shell and the wall of the exhaust device 11 below the water spray assembly 3 using a vibration isolation structure 12. The vibration isolation structure 12 is composed of a plurality of upper and lower vibration isolation units. The lower vibration isolation unit 15 is composed of a lower mounting plate 16 and a lower non-magnetic straight cylinder 17. The lower non-magnetic straight cylinder 17 can be made of a non-magnetic metal material such as copper, stainless steel, or titanium alloy. The upper portion of the inner wall of the lower non-magnetic straight cylinder 17 is provided with a lower magnetic block 19, and the bottom portion is provided with a strong magnetic block 20. The upper vibration isolation unit 21 is composed of an upper mounting plate 22 and an upper non-magnetic straight cylinder 23. The upper non-magnetic straight cylinder 23 may be made of non-magnetic metal materials such as copper, stainless steel, and titanium alloy. An upper magnetic block 25 is provided at the lower portion of the inner wall of the upper non-magnetic straight cylinder 23. A plurality of small holes are provided on the water sprinkling plate 6, and a plurality of bar magnets are installed at both ends of the water sprinkling plate 6. The bar magnets correspond to the vibration isolation units one by one. The bar magnets are divided into an N pole and an S pole. The opposing surfaces of all magnets in the vibration isolation structure 12 have the same magnetic pole. The figure is used as an example for explanation: Assuming that the S pole is on the top and the N pole is on the bottom, the side of the lower magnetic block 19 facing the N pole of the bar magnet is also set to the N pole. Similarly, the side of the upper magnetic block 25 facing the S pole of the bar magnet is also set to the S pole. The side of the strong magnetic block 20 at the bottom of the lower non-magnetic straight cylinder 17 facing the N pole of the bar magnet is also set to the N pole. Under the repulsive force of the magnets with the same poles, the bar magnet on the water sprinkling plate 6 will be in a suspended state, and under the action of the annular repulsive force of the upper and lower magnetic blocks, it will not come into contact with the upper mounting plate 22 and the lower mounting plate 16, so that the water sprinkling plate 6 and the bar magnet are completely isolated from the condenser shell, and there is no contact point, which effectively isolates the transmission path of the vibration energy of the water sprinkling plate 6 to the condenser shell; All vibration isolation units are positioned within the gaps between the liquid film 4. When the liquid film 4 falls from above, it will not impact the isolation units, but will only impact the water spray plate 6. When the liquid film 4 falls and hits the water spray plate 6, the impact force causes the water spray plate 6 to move downward. According to the principle of electromagnetic induction, when a magnet moves within a non-magnetic metal tube, such as a copper tube, an induced current is generated within the non-magnetic metal tube. This induced current generates an induced magnetic field, and the additional induced magnetic field exerts an additional force on the moving magnet, hindering its movement and thus reducing its speed. Therefore, when the water spray plate 6 moves downward, it drives the bar magnet downward, which is then subject to the additional resistance force generated by the electromagnetic induction principle, significantly reducing its downward speed and energy required for downward movement. Similarly, the upper non-magnetic straight cylinder 23 will also generate an additional electromagnetic induction resistance force that hinders the bar magnet from moving downward. Together with the resistance force generated by the lower non-magnetic straight cylinder 17, it will hinder the bar magnet from moving downward, slowing down its downward movement even more. In addition, the strong magnetic block 20 at the bottom of the lower non-magnetic cylinder 17 also generates a repulsive force on the bar magnet. As the bar magnet continues to move downward, the repulsive force becomes increasingly stronger, eventually causing the bar magnet and the water spray plate 6 to stop moving downward, achieving a balance between the impact force of the liquid film 4 and the repulsive force. The water spray plate 6 is suspended at another position, but does not contact the lower non-magnetic cylinder 17. This greatly weakens or even eliminates the vibration generated by the liquid film 4 impacting the water spray plate 6, achieving a vibration isolation effect on the water spray plate 6. The purpose of providing the upper and lower layers of non-magnetic cylinders is to utilize the resistance force generated by the principle of electromagnetic induction to significantly slow the downward movement of the water spray plate 6, preventing it from suddenly hitting the mounting plate under the impact force of the liquid film 4. At the same time, it also provides buffer time for the strong magnetic block 20 at the bottom to generate the repulsive force, thus ensuring that the water spray plate 6 remains suspended from all sides.

[0110] According to the embodiment of the present application, a low-noise hybrid condenser is proposed. Figures 7 to 9 The low-noise hybrid condenser includes a condenser housing 8, a buffer plate 30, a buffer assembly 31, and a water spray assembly 3. The condenser housing 8 defines a condensing chamber 2. The buffer assembly 31 includes a non-magnetic straight cylinder 32 and a first magnetic member 33. The non-magnetic straight cylinder 32 is mounted on the inner wall of the condensing chamber 2. A buffer chamber 34 is defined within the non-magnetic straight cylinder 32. The first end of the first magnetic member 33 is movably inserted into the buffer chamber 34, and the second end of the first magnetic member 33 is connected to the buffer plate 30. The water spray assembly 3 is mounted within the condensing chamber 2 and is provided with a nozzle 5, which faces the buffer plate 30.

[0111] According to the condenser of the embodiment of the present application, when the liquid film 4 formed by the nozzle 5 impacts the buffer plate 30, the buffer plate 30 will be subjected to the force of the liquid film 4, causing it to move toward the condenser housing 8, driving the first magnetic member 33 to move toward the condenser housing 8 within the non-magnetic straight cylinder 32. According to the principle of electromagnetic induction, the changing magnetic field generated by the movement of the first magnetic member 33 will cause the non-magnetic straight cylinder 32 to cut the magnetic lines of flux, thereby generating an induced current in the non-magnetic straight cylinder 32. The accompanying magnetic field of the induced current will in turn act on the magnet, hindering its movement and slowing down the magnet's movement, thereby acting to absorb the impact force of the buffer film 4.

[0112] It will be appreciated that condenser housing 8 is the external framework of the entire condenser and can be made of a high-strength, corrosion-resistant material, such as stainless steel. Condenser housing 8 defines a condensation chamber 2 within condenser housing 8. This chamber provides a relatively enclosed space for the condensation process, enabling efficient heat exchange within the medium to be condensed, thereby achieving a transition from gas to liquid.

[0113] The primary function of the buffer plate 30 is to withstand the impact of the liquid film 4 ejected from the water spray assembly 3. When the liquid film 4 impacts the buffer plate 30 at high speed, it deforms and moves to a certain extent, thereby absorbing and dissipating the energy of the liquid film 4 and reducing the impact on other components within the condenser. The buffer plate 30 is typically made of a material with a certain degree of elasticity and strength, such as rubber or a metal composite material, to ensure that it can effectively absorb the impact of the liquid film 4.

[0114] When the liquid film 4 formed by the nozzle 5 hits the buffer plate 30, the buffer plate 30 will be affected by the force of the liquid film 4 and move toward the condenser shell 8. Since the second end of the first magnetic part 33 is connected to the buffer plate 30, the movement of the buffer plate 30 will drive the first magnetic part 33 to move toward the condenser shell 8 in the non-magnetic straight cylinder 32. According to the principle of electromagnetic induction, the changing magnetic field generated by the movement of the first magnetic part 33 will cause the non-magnetic straight cylinder 32 to cut the magnetic flux lines, thereby generating an induced current in the non-magnetic straight cylinder 32. The induced current will generate an accompanying magnetic field, which will in turn act on the first magnetic part 33, hindering its movement, slowing down the movement speed of the first magnetic part 33, and then slowing down the movement speed of the buffer plate 30, playing the role of buffering the impact force of the buffer film 4. This buffering method can effectively protect the structure of the condenser and avoid damage to components due to excessive impact force of the liquid film 4.

[0115] According to one embodiment of the present application, the buffer assembly 31 includes a second magnetic member 35, and the second magnetic member 35 is provided on the side of the buffer cavity 34 close to the inner wall, and the side of the second magnetic member 35 close to the first magnetic member 33 has the same magnetic pole as the first end of the first magnetic member 33.

[0116] A second magnetic member 35 is disposed on the side of the buffer chamber 34 near the inner wall, and its side near the first magnetic member 33 has the same magnetic pole as the first end of the first magnetic member 33. Based on the principle of "like poles repel each other" between magnetic poles, when the first magnetic member 33 moves toward the condenser housing 8 under the impact force of the liquid film 4, the second magnetic member 35 generates an additional repulsive force on the first magnetic member 33. This repulsive force, combined with the accompanying magnetic field force generated by electromagnetic induction on the first magnetic member 33, further hinders the movement of the first magnetic member 33, thereby enhancing the effect of the impact force of the buffer film 4 and more effectively protecting the internal structure of the condenser.

[0117] The setting of the second magnetic part 35 causes the buffer assembly 31 to be affected by two forces during the buffering process (the accompanying magnetic field force generated by electromagnetic induction and the repulsive force of the second magnetic part 35). These two forces cooperate with each other to make the movement of the first magnetic part 33 more stable.

[0118] According to one embodiment of the present application, the buffer assembly 31 includes a non-magnetic rod 36 , the first end of the first magnetic component 33 is connected to the non-magnetic rod 36 , the second magnetic component 35 is provided with an inner hole 37 , and the non-magnetic rod 36 can be movably inserted into the inner hole 37 .

[0119] It is understandable that when the first magnetic member 33 moves toward the second magnetic member 35 , the non-magnetic rod 36 at the first end of the first magnetic member 33 will pass through the second magnetic member 35 and generate an induced current to hinder the movement of the non-magnetic rod 36 .

[0120] The induced current's resistance, the repulsive force of the second magnetic member 35 on the first magnetic member 33, and the associated magnetic field generated by the non-magnetic cylinder 32 cutting through the magnetic flux lines during electromagnetic induction, further enhance the buffer assembly 31's ability to cushion the impact of the liquid film 4. These multiple resistances effectively slow the movement of the first magnetic member 33 and reduce the range of motion of the buffer plate 30, thereby better protecting the condenser's internal structure.

[0121] According to one embodiment of the present application, the opening area of the inner hole 37 is larger than the cross-sectional area of the non-magnetic rod 36 .

[0122] It is understood that when the opening area of the inner hole 37 is larger than the cross-sectional area of the non-magnetic rod 36, sufficient space is provided for the non-magnetic rod 36 to move within the inner hole 37 of the second magnetic member 35. When the first magnetic member 33 is moved by the impact force of the liquid film 4, the non-magnetic rod 36 can move freely within the inner hole 37 and will not become stuck with the wall of the inner hole 37 due to the undersized inner hole 37.

[0123] According to one embodiment of the present application, the buffer assembly 31 includes a rolling structure 38 , which is disposed between the first magnetic member 33 and the non-magnetic straight cylinder 32 to reduce movement resistance.

[0124] The rolling structure 38 is located between the first magnetic member 33 and the non-magnetic cylinder 32 to reduce motion resistance. The rolling structure 38 is a device that creates rolling friction between two relatively moving components. The rolling structure 38 can be composed of rolling elements (such as balls, rollers, or needle rollers) and a cage. The rolling elements roll between the two components, converting sliding friction into rolling friction, thereby significantly reducing motion resistance.

[0125] According to one embodiment of the present application, the rolling structure 38 is a flexible rolling structure 38 .

[0126] It is understood that the flexible rolling structure 38 is disposed between the first magnetic member 33 and the non-magnetic cylinder 32 to reduce resistance to movement. The flexible rolling structure 38 is a special rolling structure 38 that combines the characteristics of a rolling structure 38 and a flexible material. Flexible materials are deformable and can adapt to different shapes and stress conditions to a certain extent. The flexible rolling structure 38 can be composed of a rolling element (such as a rubber ball, silicone roller, etc.) and a retaining frame made of a flexible material. The rolling element rolls between the two components, and the flexible material can undergo slight deformation to better accommodate the relative movement and contact between the first magnetic member 33 and the non-magnetic cylinder 32.

[0127] According to one embodiment of the present application, a snap-fit structure 39 is provided at one end of the non-magnetic straight cylinder 32 close to the buffer plate 30 , and an opening area of the snap-fit structure 39 is smaller than a cross-sectional area of the first end of the first magnetic member 33 .

[0128] The opening area of the snap structure 39 is smaller than the cross-sectional area of the first end of the first magnetic member 33. This prevents the first magnetic member 33 from escaping from the non-magnetic cylinder 32 through the opening of the snap structure 39 when the snap structure 39 is in position. When the first magnetic member 33 is subjected to forces such as the impact of the liquid film 4, it will move within the non-magnetic cylinder 32. However, due to the obstruction of the snap structure 39, the first magnetic member 33 can only move within the limited space between the snap structure 39 and the buffer plate 30. This effectively prevents the first magnetic member 33 from escaping from the non-magnetic cylinder 32 and ensures the normal operation of the buffer assembly 31.

[0129] According to one embodiment of the present application, there are multiple buffer assemblies 31 , and the multiple buffer assemblies 31 are distributed along the extension direction of the buffer plate 30 .

[0130] When the impact force of the liquid film 4 acts on the buffer plate 30, the force is dispersed among the multiple buffer components 31 because the multiple buffer components 31 are distributed along the extension direction of the buffer plate 30. Each buffer component 31 provides a certain degree of buffering to the force, thus preventing the force from being concentrated on one or a few points, and achieving a more uniform buffering effect.

[0131] At the same time, in actual applications, the distribution of the applied force on the buffer plate 30 is often uneven. By providing multiple buffer components 31, the number and position of the buffer components 31 can be reasonably adjusted according to the actual distribution of the applied force, so that each buffer component 31 can fully exert its buffering effect, further improving the uniformity of the buffering.

[0132] According to an embodiment of the present application, the non-magnetic straight cylinder 32 is one of a copper straight cylinder, a stainless steel straight cylinder, and a titanium alloy straight cylinder.

[0133] According to one embodiment of the present application, the buffer plate 30 is one of a stainless steel plate, an aluminum alloy plate, and a titanium alloy plate.

[0134] In one embodiment, a steam inlet 2131 is provided on the top of the condenser shell 8 , and a condensate outlet 279 is provided on the bottom of the condenser shell 8 .

[0135] In one embodiment, an air extraction device 11 is provided at the bottom of the water spray assembly 3 , and the air extraction device 11 is connected to a cooling water pipe 10 .

[0136] The condenser of the present application is described below with reference to a specific embodiment: As shown in the figure, a buffer plate 30 is installed on the inner wall of the shell where the condenser collides with the liquid film 4. The buffer plate 30 is made of corrosion-resistant materials such as stainless steel, aluminum alloy, and titanium alloy; A plurality of first magnetic members 33 are mounted on the back of the buffer plate 30. The first magnetic members 33 may be in various shapes such as cylindrical and cubic shapes. One end of the first magnetic member 33 is fastened to the buffer plate 30, and the other end is placed in a straight tube. The shape of the straight tube matches the magnet block. The material of the straight tube can be non-magnetic materials such as copper and stainless steel. Copper is used as an example for illustration. A buckle is provided between the first magnetic member 33 and the non-magnetic straight tube 32 to prevent the first magnetic member 33 from being separated from the non-magnetic straight tube 32; A second magnetic member 35 is also fixed to the bottom of the non-magnetic straight cylinder 32. The second magnetic member 35 has the same magnetic pole as the first magnetic member 33 on the buffer plate 30, so that the two magnets are in a state of repulsion. At the lower front end of the first magnetic member 33, a plurality of rolling structures 38 can be arranged to not only reduce the resistance of the first magnetic member 33 during movement, but also reduce the direct transmission of vibration to the non-magnetic straight cylinder 32; A non-magnetic rod 36 is installed in the middle of the front end of the first magnetic part 33, and a through hole 7 slightly larger than the non-magnetic rod 36 is opened in the middle of the second magnetic part 35. When the buffer plate 30 moves to the left, the non-magnetic rod 36 will also be inserted into the through hole 7 in the middle of the second magnetic part 35.

[0137] When the liquid film 4 formed by the nozzle 5 impacts the buffer plate 30, the buffer plate 30 is subjected to a leftward force, causing it to move leftward, driving the first magnetic member 33 to move leftward within the non-magnetic cylinder 32. According to the principle of electromagnetic induction, the changing magnetic field generated by the movement of the magnet will cause the non-magnetic cylinder 32 to cut the magnetic flux lines, thereby generating an induced current in the non-magnetic cylinder 32. The accompanying magnetic field of the induced current will in turn act on the magnet, hindering its movement and slowing its movement, thus acting to buffer the impact force of the buffer film 4. Considering that the resistance force generated by the induced current can only slow down the first magnetic member 33 but cannot completely prevent it from moving to the left, in order to prevent it from colliding with the condenser shell and causing vibration to be transmitted outward, a second magnetic member 35 with the same magnetic pole is installed at the bottom of the non-magnetic straight cylinder 32. As the first magnetic member 33 continues to approach, a greater repulsive force will be generated between the two magnets, thereby preventing the first magnetic member 33 from colliding with the second magnetic member 35. When the first magnetic member 33 moves to the left, the non-magnetic rod 36 installed at its front end will also move to the left and insert into the second magnetic member 35 , which will also generate an induced current to hinder the movement of the non-magnetic rod 36 .

[0138] The resistance force generated by the electromagnetic induction principle of the two parts plays a great buffering role, which can prevent the repulsive force between the two magnets from increasing suddenly, prolong the buffering and vibration isolation time, and play a role similar to slow pressure relief, thereby greatly reducing the impact of the liquid film 4.

[0139] During the entire process, since the buffer plate 30 and the first magnetic part 33 are not in contact with the second magnetic part 35 and the condenser shell, the vibration caused by the collision of the liquid film 4 can be greatly reduced and transmitted outward, thereby greatly reducing the vibration noise of the mixing condenser and realizing the low-noise design of the condenser.

[0140] In addition, when the mixing condenser stops running, the nozzle 5 no longer produces the liquid film 4, and the impact force applied to the buffer plate 30 will disappear. At this time, under the action of the repulsive force of the magnet block, the first magnetic part 33 will move to the right. The additional resistance force generated by the electromagnetic induction current at this time will hinder the first magnetic part 33 from moving to the right, thereby slowing down its rightward movement. The first magnetic part 33 will not move quickly to the right under the action of the magnetic repulsive force and hit the snap structure of the non-magnetic straight cylinder 32, but will move slowly to the right. In this way, the mixing condenser can be kept in a low vibration state throughout the entire process.
