Description

Technical Field

[0001] This utility model belongs to the field of cooling equipment technology, specifically relating to an industrial cooler and a cooling system including the industrial cooler. Background Technology

[0002] Existing industrial coolers are widely used in power, metallurgy, and other fields. For example, traditional transformer oil radiators include a two-chamber assembly and a core assembly positioned between the two chambers. The core assembly includes harmonica tubes arranged in a multi-layered array along the vertical axis, with spirally folded feather fins installed within the harmonica tubes. This type of cooler increases the heat exchange area by incorporating the spirally folded feather fin structure, thereby improving the heat exchange efficiency of the industrial cooler. However, the spirally folded feather fin structure enhances turbulence through a continuous spiral design. When all layers of harmonica tubes have this structure, it leads to the accumulation of frictional resistance in the oil flow path, affecting oil circulation efficiency. If the oil flow velocity decreases, it may weaken the overall heat exchange capacity of the radiator, thus affecting the heat dissipation effect of the industrial cooler. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an industrial cooler comprising a left oil chamber assembly, a right oil chamber assembly, and a core assembly disposed between the two. The two ends of the core assembly are in fluid communication with the left and right oil chamber assemblies, respectively. The lower ends of both the left and right oil chamber assemblies are provided with connectors. The core assembly includes harmonica tubes arranged in a multi-layer array along the vertical axis. The bottom and top harmonica tubes are equipped with spirally folded feather fins, and the middle layer of harmonica tubes is configured with W-shaped positive peak turbulence fins.

[0006] As a further improvement to the aforementioned industrial cooler, the bottom and top harmonica tubes are fitted with spiral folded feather fins by welding, and the middle harmonica tubes are configured with W-shaped positive peak turbulence fins by welding.

[0007] As a further improvement to the aforementioned industrial cooler, the spiral folded feather fins and W-shaped positive peak turbulence fins are made of aluminum alloy.

[0008] As a further improvement to the aforementioned industrial cooler, W-shaped positive peak turbulence fins are provided on both the front and rear sides of the intermediate harmonica tube.

[0009] As a further improvement to the aforementioned industrial cooler, at least one of the left and right oil chamber assemblies is equipped with a color-changing sensor, which triggers a color change based on pressure changes. In use, the sensing pressure can be set according to specific requirements.

[0010] As a further improvement to the aforementioned industrial cooler, the color-changing sensors are respectively disposed on the top end faces of the left oil chamber assembly and the right oil chamber assembly.

[0011] As a further improvement to the aforementioned industrial cooler, the color-changing sensor is configured to display a first color indicator when the pressure is normal and to automatically switch to a second color indicator when the pressure is abnormal.

[0012] As a further improvement to the aforementioned industrial cooler, the first color identifier is green, and the second color identifier is red. In actual use, in customer customization, these colors can be used selectively and routinely according to requirements.

[0013] As a further improvement to the aforementioned industrial cooler, both the left and right oil chamber assemblies include a connected manifold and several branch pipes, wherein the branch pipes are circular tubes. This effectively improves airflow and allows this structure to be applied to large-scale heat dissipation systems.

[0014] As a further improvement to the aforementioned industrial cooler, the connecting component is a connecting flange or a bellows.

[0015] As a further improvement to the aforementioned industrial cooler, the manifold integrates a detachable filter unit at the docking end of the connector.

[0017] As a further improvement to the aforementioned industrial cooler, the core assembly is provided with reinforcing ribs, which are fixed to the core assembly via a snap-fit ​​connection structure.

[0018] As a further improvement to the aforementioned industrial cooler, the manifold of the left oil chamber assembly includes a vertically extending upper manifold, a horizontally extending middle manifold, and a vertically extending lower manifold. The two ends of the middle manifold are in fluid communication with the upper manifold and the lower manifold, respectively. The upper manifold is located to the right of the lower manifold, and the lower end of the lower manifold is provided with the connecting member.

[0019] As a further improvement to the aforementioned industrial cooler, a fixing block is provided at the bend and corner connection between the upper section manifold and the middle section manifold; and / or, a fixing block is provided at the bend and corner connection between the lower section manifold and the middle section manifold.

[0021] This industrial cooler utilizes spirally folded feather-like fins at the bottom and top layers to create an axially guided flow field, reducing pressure loss at the oil inlet and outlet and enhancing longitudinal heat exchange efficiency. The middle layer's W-shaped positive peak turbulence fins generate transverse vortices through a periodic peak-valley structure, breaking the laminar boundary layer and significantly improving oil flow disturbance intensity and heat dissipation uniformity. The synergistic effect of these two elements avoids the high-flow heat dissipation defects of a fully spiral structure while overcoming the limitations of a single W-shaped fin in axial guidance, forming a longitudinal and transverse airflow. This ultimately achieves the technical effects of improved heat dissipation efficiency and reduced pressure drop, while stress dispersion design extends the structural lifespan.

[0038] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0039] Please refer to the accompanying drawings. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the content disclosed herein. They are not intended to limit the implementation of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed herein.

[0040] In the description of this utility model, it should be noted that the orientations or positional relationships indicated by the terms used are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] To facilitate the description of directional relationships, this article stipulates that the directions of up, down, left, and right mentioned below are the same as those in the diagram. Figure 1 The corresponding directions remain consistent, that is, with Figure 1 The spatial coordinate system shown in the diagram is the reference. It should be noted that this orientation definition system differs fundamentally from conventional geographical orientation, and the determination of relevant parameters should strictly follow the coordinate system shown in the diagram.

[0042] Please see Figures 1 to 6 As shown, an embodiment of this utility model provides an industrial cooler, including a left oil chamber assembly 1, a right oil chamber assembly 2, and a core assembly 3 disposed between the two. Both ends of the core assembly 3 are in fluid communication with the left oil chamber assembly 1 and the right oil chamber assembly 2, respectively. The lower ends of both the left and right oil chamber assemblies 1 and 2 are provided with connectors. The core assembly 3 includes harmonica tubes arranged in a multi-layer array along the vertical axis. The bottom and top harmonica tubes are equipped with spirally folded feather fins, and the middle layer harmonica tubes are equipped with W-shaped positive peak turbulence fins. Specifically, the bottom layer harmonica tubes refer to the lowest layer of harmonica tubes along the vertical axis of the core assembly 3, and the top layer harmonica tubes refer to the highest layer of harmonica tubes along the vertical axis of the core assembly 3. The harmonica tubes between the bottom and top layers are all middle layer harmonica tubes. The connector is used to connect the transformer. The connector can be a connecting flange or a bellows structure. The bellows has the advantage of a large working margin. Its unique axial compensation capability not only provides a larger installation tolerance space for the pipeline system, but also significantly improves the flexibility of equipment layout, enabling the installation operation to adapt to diverse site conditions.

[0043] In the above embodiments, the core assembly 3 includes harmonica tubes arranged in a multi-layer array along the vertical axis. The bottom and top harmonica tubes are equipped with spirally folded plume fins, and the middle layer harmonica tubes are equipped with W-shaped positive peak turbulence fins. That is, the harmonica tube array implements a gradient fin configuration scheme along the vertical axis: the bottom and top tube bundles are equipped with spirally folded plume fins, and the middle layer tube bundles are equipped with W-shaped positive peak turbulence fins. The spirally folded plume fins, through a continuous swirling channel design, can effectively induce air convection, and combined with the acceleration effect of the top hot airflow, form a self-reinforcing chimney effect of thermal pressure difference in the vertical direction. In contrast, the W-shaped positive peak turbulence fins, with their multi-peak folding flow channel characteristics, can achieve an increase in heat exchange surface area under the same projected area. Their alternating peak-trough geometric configuration allows for an increase in fin density, significantly optimizing the space utilization of the heat dissipation unit. It is understood that the spiral folding feather fins of this utility model can be designed with reference to existing spiral fins, and the W-shaped positive peak turbulence fins can be designed with reference to existing corrugated fins.

[0044] As described above, the industrial cooler of this invention features spirally folded feather-like fins at the bottom and top layers that form an axially guided flow field, reducing pressure loss at the oil inlet and outlet and enhancing longitudinal heat exchange efficiency. The middle layer's W-shaped positive peak turbulence fins generate transverse vortices through a periodic peak-valley structure, breaking the laminar boundary layer and significantly improving oil flow disturbance intensity and heat dissipation uniformity. The synergistic effect of these two elements avoids the high-flow heat dissipation defects of a fully spiral structure and overcomes the shortcomings of a single W-shaped fin in axial guidance capability, forming a longitudinal and transverse airflow. This ultimately achieves the technical effects of improved heat dissipation efficiency and reduced pressure drop, while stress dispersion design extends the structural lifespan.

[0045] In some embodiments of this invention, the bottom and top harmonica tubes are fitted with spirally folded plume fins by welding, while the middle harmonica tubes are configured with W-shaped positive peak turbulence fins by welding. The welded connection between the spirally folded plume fins and the W-shaped positive peak turbulence fins ensures a tight bond between the fins and the harmonica tubes through a stable welding process, effectively improving the overall structural strength and heat transfer efficiency. The application of spirally folded plume fins in the bottom and top layers optimizes the axial distribution of oil flow, while the W-shaped fins in the middle layer enhance the lateral turbulence effect. The synergistic effect of these two elements significantly improves the uniformity of heat dissipation. Simultaneously, the welding process avoids the risk of loosening that may occur with traditional snap-fit ​​connections, extending the service life of the equipment.

[0046] In some embodiments of this invention, the spiral folded plume fins and W-shaped positive peak turbulence fins are made of aluminum alloy. The use of aluminum alloy fins fully leverages the advantages of aluminum alloy's lightweight and high thermal conductivity, significantly reducing the overall weight of the cooler while ensuring heat dissipation performance. The excellent corrosion resistance of aluminum alloy further extends the service life of the fins in oil-medium environments, and its good forming and processing characteristics provide technological feasibility for the precision manufacturing of complex fin structures, balancing performance and cost-effectiveness. Furthermore, the implementation of the spiral folded plume fins and W-shaped positive peak turbulence fins using aluminum alloy fins demonstrates significant technical advantages: under equivalent heat dissipation power conditions, the heat transfer efficiency per unit mass of aluminum alloy fins is approximately three times higher than that of conventional carbon steel fins. This means that a single aluminum fin assembly can achieve three times the comprehensive heat exchange performance of carbon steel fins.

[0047] In some embodiments of this invention, W-shaped positive peak turbulence fins are arranged on both the front and rear sides of the intermediate harmonica tube. This symmetrical turbulence structure achieves bidirectional turbulence of the oil flow in the vertical direction, completely eliminating the temperature stratification phenomenon that might occur with fins on only one side. This layout increases the heat exchange area and shortens the oil flow residence time through the bidirectional vortex effect, effectively suppressing the risk of localized overheating of the oil flow while improving heat dissipation efficiency. The front-rear direction is perpendicular to the plane of the paper, and is perpendicular to the left-right direction and the up-down direction.

[0048] In some embodiments of this invention, at least one of the left oil chamber assembly 1 and the right oil chamber assembly 2 is provided with a color-changing sensor 4, which triggers color conversion based on pressure changes. The color-changing sensor 4 can be a pressure-induced color-changing pressure sensor, a mature existing technology that converts physical quantities into electrical signals. Its principle is based on how pressure changes the structure of the crystal inside the sensor, thereby changing the color of the crystal and generating an electrical signal output. This type of sensor is widely used in industrial automation fields such as machining, automotive, and aerospace.

[0049] In some embodiments of this utility model, both the left oil chamber assembly 1 and the right oil chamber assembly 2 include a connected manifold 5 and several branch pipes 6. The manifold 5 has several oil passages (not shown in the figure), and the branch pipe 6 has a guide port (not shown in the figure) and several branch ports (not shown in the figure). The guide port of the branch pipe 6 is welded to the oil passage of the manifold 5. Preferably, the number of branch ports on the branch pipe 6 is not less than four. The core assembly 3 includes several harmonica tubes (not shown in the figure), which are arranged in several rows and columns. The harmonica tubes are welded to the branch ports of the branch pipe 6. The upper end of the manifold 5 is provided with the connecting member. In a preferred embodiment of this utility model, the branch pipe 6 is a circular tube structure, that is, the branch pipe 6 adopts an integral circular tube structure design, which has better deformation resistance than irregularly shaped or square tubes. The circular cross-section not only effectively resists mechanical damage during transportation and installation, but its uniform stress distribution also endows the pipeline system with excellent structural stability and load-bearing capacity. In airflow, it further enhances airflow compared to a square cross-section. It should be noted that the structures of the left oil chamber assembly 1, right oil chamber assembly 2, core assembly 3, etc., of this utility model can be referenced in Chinese patent documents CN211181879U and CN214476857U. The color-changing sensor 4 enables real-time monitoring and visual alarm of oil chamber pressure status. The color change intuitively indicates abnormalities, which is beneficial for directly capturing the chromatographic features of the sensor through the UAV multispectral imaging system, establishing an intelligent diagnostic closed loop. Compared with manual inspection, it significantly reduces manpower costs. Compared with existing remote monitoring systems, it eliminates the need to deploy complex systems such as video surveillance and communication modules, thereby eliminating redundant components such as video surveillance modules and data communication units, simplifying system complexity, reducing overall system costs, reducing data transmission latency, and providing a more intuitive and faster response. It also demonstrates excellent adaptability and maintenance economy in distributed application scenarios such as grid terminals and energy base stations, and is especially suitable for remote or dispersed equipment.

[0050] In some embodiments of this utility model, the manifold 5 integrates a detachable filter unit (not shown in the figure) at the docking end of the connector. This filter unit has multiple layers of filter media and a bidirectional interception function, which can effectively block metal wear debris generated inside the radiator and external mechanical impurities carried by the transformer oil circuit. By establishing a double isolation barrier, it fundamentally filters metal particles or impurities in the oil system, ensuring that both hydraulic circuits always maintain the cleanliness level required by the design. This configuration can be selected by customers and produced in a standardized manner. In use, according to customer requirements, a transformer oil filter can be made with 300 to 1000 mesh steel wire mesh, which can ensure that the oil in the radiator maintains normal cleanliness. At the same time, in future equipment maintenance, the filter can be directly removed for cleaning without dismantling the entire oil radiator, ensuring the stability of the equipment and achieving cost reduction and efficiency improvement in terms of manpower and material resources.

[0051] In some embodiments of this utility model, the color-changing sensor 4 is respectively disposed on the top end face of the left oil chamber assembly 1 and the right oil chamber assembly 2, that is, the top end face of the left oil chamber assembly 1 and the right oil chamber assembly 2 are both provided with the color-changing sensor 4. Specifically, optionally, the color-changing sensor 4 is respectively disposed on the top end face of the manifold 5 of the left oil chamber assembly 1 and the manifold 5 of the right oil chamber assembly 2.

[0052] In some embodiments of this invention, the color-changing sensor 44 is configured to display a first color indicator when the pressure is normal and automatically switch to a second color indicator when the pressure is abnormal. This dual-color automatic switching mechanism provides graded identification of pressure states, clearly distinguishing between normal and abnormal pressure states, enhancing the visual warning effect, and eliminating the need for manual intervention. The automatic color switching under abnormal pressure reduces the risk of missed detections. This mechanical physical identification avoids the complex principles of electrical identification and extends its service life. However, it can also be selectively configured in typical community environments.

[0053] In some embodiments of this invention, the first color identifier is green, and the second color identifier is red. The internationally recognized red / green warning code is used to reduce the probability of false positives, and red has strong penetrating power in the visible spectrum, facilitating long-distance inspection and capture of abnormal signals by drones.

[0054] In some embodiments of this utility model, at least one of the left oil chamber assembly 1, the right oil chamber assembly 2, and the core assembly 3 has an anti-corrosion nano-coating (not shown in the figure) on its inner and outer surfaces. The anti-corrosion nano-coating provides full protection for both inner and outer surfaces, significantly improving resistance to oil corrosion, mechanical impact, and oil stain adhesion, thus extending the service life of the radiator. This anti-corrosion nano-coating can be polyurethane, epoxy resin, or nano-metal. It should be noted that nano-coatings are a mature existing technology. For example, Chinese patent document CN118206890A discloses an anti-corrosion and waterproof coating composed of graphene two-dimensional nanomaterials; Chinese patent document CN118222153A discloses a highly hydrophobic ZIF nanoparticle-modified anti-corrosion coating; and Chinese patent document CN112063265B discloses a protective coating and its preparation method and application.

[0055] In some embodiments of this utility model, the core assembly 3 is provided with a reinforcing rib 8, which is fixed to the core assembly 3 by a snap-fit ​​connection structure. The snap-fit ​​reinforcing rib 8 enhances the compressive deformation resistance of the core assembly 3, while simplifying the disassembly and assembly process and reducing the risk of structural damage during maintenance. Specifically, optionally, the reinforcing rib 8 is provided with a slot, which cooperates with the snap-fit ​​on the harmonica tube to make the reinforcing rib 8 more secure.

[0056] In some embodiments of this utility model, the manifold 5 of the right oil chamber assembly 2 includes a vertically extending upper manifold 9, a horizontally extending middle manifold 10, and a vertically extending lower manifold 11. The two ends of the middle manifold 10 are in fluid communication with the upper manifold 9 and the lower manifold 11, respectively. The upper manifold 9 is located to the right of the lower manifold 11. The lower end of the lower manifold 11 is provided with the connecting member. A color-changing sensor 4 is provided on the top end face of the upper manifold 9. The horizontal middle manifold 10 facilitates connection with external pipes, improving installation adaptability. In this example, the manifolds are distributed in an up-and-down configuration. In practice, the manifolds can also be distributed in either an up-and-down or left-and-right configuration. The middle portion of the manifold can adjust the heat dissipation area. This circular tube structure is rare in large aluminum alloy heat dissipation applications. Optionally, the two ends of the middle section manifold are connected to the upper section manifold and the lower section manifold respectively by welding to form fluid communication, so that the cooling medium can achieve the desired heat dissipation effect inside the pipe.

[0057] In some embodiments of this utility model, such as Figure 2As shown, a fixing block 12 is provided at the bend and corner connection between the upper section manifold 9 and the middle section manifold 10; and / or, a fixing block 12 is provided at the bend and corner connection between the lower section manifold 11 and the middle section manifold 10. Adding a fixing block 12 at the bend of the manifold 5 disperses the oil pressure impact stress, suppresses the risk of weld cracking, and reduces vibration noise caused by oil flow pulsation.

[0058] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the left oil chamber assembly 1 is provided with a lifting lug 13 on the side facing away from the core assembly 3; and / or, the right oil chamber assembly 2 is provided with a lifting lug 13 on the side facing away from the core assembly 3. The lifting lug 13 is designed to achieve safe lifting and positioning, avoid deformation of the oil chamber, and assist in the installation direction calibration through position markings to prevent oil circuit blockage caused by reverse assembly.

[0059] In some embodiments of this invention, the color-changing sensor is connected to the industrial cooler via a threaded connection. When the industrial cooler's temperature exceeds 85 degrees Celsius and the relative pressure increases, the color-changing sensor changes color, eliminating the need for an external battery and avoiding unnecessary maintenance and replacement. In summary, the industrial cooler of this invention features spirally folded feather-like fins at the bottom and top layers forming an axially guided flow field, reducing pressure loss at the oil inlet and outlet and enhancing longitudinal heat exchange efficiency. The middle layer's W-shaped positive peak turbulence fins generate transverse vortices through a periodic peak-valley structure, breaking the laminar boundary layer and significantly improving oil flow disturbance intensity and heat dissipation uniformity. The synergistic effect of these two elements avoids the high-flow heat dissipation defects of a fully spiral structure and overcomes the shortcomings of a single W-shaped fin in axial guidance capability, forming a longitudinal and transverse airflow. This ultimately achieves the technical effects of improved heat dissipation efficiency and reduced pressure drop, while stress dispersion design extends the structural lifespan.

[0060] This utility model's industrial cooler uses a color-changing sensor 4 to achieve real-time monitoring and visual alarm of the oil chamber pressure status. The color change intuitively indicates abnormalities, which is beneficial for directly capturing the sensor's chromatographic features through a UAV multispectral imaging system, establishing an intelligent diagnostic closed loop. Compared with manual inspection, this significantly reduces manpower costs. Compared with existing remote monitoring systems, it eliminates the need to deploy complex systems such as video surveillance and communication modules, thereby avoiding redundant components such as video surveillance modules and data communication units, simplifying system complexity, reducing overall system costs, reducing data transmission latency, and providing a more intuitive and faster response. It also demonstrates excellent adaptability and maintenance economy in distributed application scenarios such as grid terminals and energy base stations, and is especially suitable for remote or dispersed equipment.

[0061] This invention relates to an industrial cooler that directly reflects pressure status through color changes. Drone identification eliminates the need for data transmission delays, making it more intuitive and faster-responding. Color alarms are triggered by minute pressure changes, providing early warnings of potential risks. It reduces reliance on complex monitoring platforms, allowing drone inspections to cover multiple devices and lowering labor costs. For transformers in the field, the use of drone inspections and sensor color changes simplifies system complexity, making it particularly suitable for remote or dispersed equipment. Therefore, this invention employs intuitive physical color changes as alarm signals, combined with automatic drone inspection to lock onto the sensor head color, achieving unmanned, visual monitoring. It is more suitable for transformers in the field, in dispersed locations, or unattended environments, and adapts to harsh conditions.

[0062] An embodiment of this utility model also provides a cooling system, including: a transformer (not shown in the figure), which can be a power transformer, the transformer being equipped with an industrial cooler as described in any one of the above embodiments, the industrial cooler being connected to the transformer via a connector.

[0063] In some embodiments of this utility model, the cooling system further includes an inspection drone (not shown in the figure). The inspection drone is equipped with a visual recognition module (not shown in the figure), which is configured to identify the color display status of the color-changing sensor 4 of the industrial cooler. During use, when the transformer pressure exceeds a set range, the inspection drone can identify the color status based on the collected icon. The inspection drone is equipped with a visual recognition module configured to identify the color display status of the color-changing sensor 4 of the industrial cooler. By using a drone equipped with a visual recognition module to conduct batch inspections of the radiator color status, multi-device clustered intelligent monitoring is achieved, and system-level fault points can be quickly located by combining abnormal distribution data.

[0064] This system innovatively utilizes the colorimetric-pressure response characteristics of pressure-sensitive materials to achieve real-time visual feedback of oil pressure status through color changes. UAV optical recognition technology effectively avoids data transmission delays and significantly improves response speed. A pressure micro-change triggering mechanism is constructed to achieve early warning of potential faults. The system features a groundbreakingly simplified monitoring architecture design, relying on the multi-device synchronous monitoring capabilities of UAV swarm inspections to significantly reduce maintenance manpower requirements. Specifically designed for field applications, it integrates UAV mobile inspections with sensor colorimetric self-display functions, enhancing the system's lightweight architecture and making it perfectly suited for geographically dispersed and harsh-environment unattended transformer groups.

[0065] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
