A flat air radiator

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 2024200253555, filed with the Chinese Patent Office on January 4, 2024, entitled “A Flat Plate Air Radiator,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the technical field of heat dissipation equipment, and in particular to a flat-plate air radiator. Background Art

[0004] Air radiator is a basic heat dissipation device that uses air to cool fluid. It is often configured in conjunction with water-cooling units and refrigeration units. Reasonable configuration ultimately enables the project's external cooling to achieve the goals of energy saving, consumption reduction, and emission reduction. It is widely used in power grids, energy storage, petroleum and petrochemicals, wind power and other fields.

[0005] An air radiator primarily consists of a frame, fins, fan, and tube bundle. Cooling water flows within the tube bundle. The manufacturing process requires welding the tube bundle according to the designed piping, which inevitably leaves residual welding slag, oil, and other contaminants within the tube bundle. Therefore, the equipment must be pickled before shipment. Furthermore, although the cooling water is treated by a water treatment system during operation, after extended use, residual calcium and magnesium ions and acid carbonates in the cooling water can form carbonates as they flow through the inner surfaces of the cooling tube bundle. Furthermore, dissolved oxygen in the cooling water can cause metal corrosion, forming rust. This rust reduces the heat transfer efficiency of the air radiator. Severe scaling can even clog the tubes, rendering the heat transfer ineffective. Therefore, regular high-pressure water and chemical pickling are necessary for the interior of the equipment. Due to the structural limitations of traditional air radiators, the long-span tube bundles and complex pipe routes, many problems arise during equipment cleaning. The fundamental reason is that the internal fluid of the equipment cannot be completely emptied, and deposits such as scale cannot be thoroughly removed. The acid corrodes the equipment and forms leaks. The residual acid causes secondary corrosion or under-scale corrosion to the material, ultimately leading to equipment replacement. The second problem is that the vibration generated by the high-speed flow of fluid inside the tube bundle is transmitted to the frame through the tube bundle. The superimposed vibration caused by the fins facing the wind will cause the entire equipment to be in an extremely unstable state due to vibration, while also causing excessive noise.

[0006] Utility Model Content

[0007] The present disclosure aims to provide a flat-plate air radiator to solve one or more technical problems existing in the prior art and at least provide a beneficial option or create conditions.

[0008] The technical solutions adopted to solve the above technical problems are:

[0009] The present disclosure provides a flat-plate air radiator, comprising a frame, wherein the frame is provided with a heat dissipation assembly and a plurality of support members, wherein the heat dissipation assembly comprises a plurality of heat dissipation tubes obliquely arranged on the frame, wherein the two ends of the plurality of heat dissipation tubes are respectively a collecting tube end and a non-collecting tube end, and the non-collecting tube end is higher than the collecting tube end, the plurality of support members are obliquely arranged, and the support members are configured to support the plurality of heat dissipation tubes, and a plurality of fans arranged at intervals are provided on the top of the frame.

[0010] The beneficial effects of the present disclosure are:

[0011] Since the heat dissipation tubes are arranged at an angle, welding slag, oil stains and other residues are discharged from the heat dissipation tubes by gravity along with the water flow during cleaning. Therefore, during the internal pickling before shipment and the operation and maintenance cleaning, it can effectively ensure that the impurities and acid residues inside the heat dissipation tube bundle are efficiently emptied, and the internal acid circulation and alkali neutralization are completed with the minimum water resources and time, thereby extending the equipment life and reducing maintenance costs.

[0012] As a further improvement to the above technical solution, the support member includes a support plate having multiple support holes for the heat pipes to pass through, with gaps between the support holes and the heat pipes. Due to the structural limitations of traditional air radiators, long-span tube bundles, and complex pipe runs, the provision of multiple support plates can provide better support.

[0013] As a further improvement to the above technical solution, the support member further includes a support pad, the support pad having an inclined surface consistent with the inclination angle of the heat dissipation pipe, and the bottom of the support plate is located on the inclined surface. The support pad can adjust the inclination of the support plate to facilitate the installation of the support plate.

[0014] As a further improvement to the above technical solution, the frame further comprises a plurality of support tubes arranged side by side with the heat pipes. The support tubes are fixedly connected to the heat dissipation assembly and the support plate, with gaps between the support holes and the heat pipes. The heat pipes of the heat exchange tube bundle are fixed to the frame via the support tubes and do not directly contact the frame. The tube fins and the weight of the heat exchange tube bundle are integrally secured by the support tubes and the frame. The support tubes do not flow through the fluid and do not participate in the heat exchange. In this way, vibrations generated by the fluid passing through the heat exchange tubes are not transmitted to the frame, thereby ensuring the overall stability of the equipment.

[0015] As a further improvement to the above technical solution, the frame is provided with a through hole, through which the heat exchange pipe passes, with a gap between the heat exchange pipe and the through hole. This prevents the heat exchange pipe from directly contacting the frame, and vibrations generated by the fluid passing through the heat exchange pipe are not transmitted to the frame, thereby ensuring the overall stability of the device.

[0016] As a further improvement of the above technical solution, the plurality of support tubes are divided into two rows, and the two rows of support tubes are respectively located on both sides of the plurality of heat dissipation tubes, thereby achieving a better supporting effect.

[0017] As a further improvement of the above technical solution, a plurality of support tubes are arranged at equal intervals on the frame to achieve a better supporting effect.

[0018] As a further improvement of the above technical solution, the water inlet end of the heat dissipation pipe is connected to the main pipe, the main pipe is arranged on the frame, and the water outlet end of the heat dissipation pipe is connected to the liquid outlet pipe. The main pipe and the liquid outlet pipe can also play a role in supporting the heat dissipation pipe.

[0019] As a further improvement of the above technical solution, the inclination angle of the heat dissipation pipe ranges from 4 to 5 degrees.

[0020] As a further improvement of the above technical solution, a support portion is provided at the bottom of the frame, which is configured to support the frame so that the frame is in a suspended state. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Air radiator is a basic heat dissipation device that uses air to cool fluid. It is often configured in conjunction with water-cooling units and refrigeration units. Reasonable configuration ultimately enables the project's external cooling to achieve the goals of energy saving, consumption reduction, and emission reduction. It is widely used in power grids, energy storage, petroleum and petrochemicals, wind power and other fields.

[0032] There are currently two main problems with air radiators: one is the cleaning residue problem, and the other is the noise problem caused by vibration generated by the high-speed flow of fluid inside the tube bundle.

[0033] First, there's the issue of cleaning residue. An air radiator primarily consists of a frame 100, fins, a fan, and a tube bundle. Cooling water flows within the tube bundle, and the manufacturing process requires welding the tube bundle according to the designed pipe flow. This inevitably leaves residual welding slag, oil, and other residues within the tube bundle, necessitating acid cleaning before the equipment leaves the factory. Furthermore, although the cooling water undergoes water conditioning during use, after extended use, residual calcium, magnesium ions, and acid carbonates in the cooling water can lead to carbonate formation when flowing through the inner surface of the cooling tube bundle. Furthermore, dissolved oxygen in the cooling water can cause metal corrosion, forming rust. This rust reduces the heat transfer efficiency of the air radiator, and severe scaling can clog the tubes, rendering the heat transfer ineffective. Therefore, the interior of the equipment requires regular high-pressure water cleaning combined with chemical acid cleaning. Due to the structural limitations of traditional air radiators, long-span tube bundles, and complex pipe routes, many problems arise during equipment cleaning. The root cause is the inability to completely drain the fluid inside the equipment and thoroughly remove deposits such as scale. Acid corrodes the equipment, forming leaks. Residual acid causes secondary corrosion or under-scale corrosion on the material, ultimately leading to equipment replacement.

[0034] The second problem is that the vibration generated by the high-speed flow of fluid inside the tube bundle is transmitted to the frame 100 through the tube bundle. The superimposed vibration caused by the fins facing the wind will cause the entire device to be in an extremely unstable state due to vibration, and cause excessive noise.

[0035] Therefore, the present invention optimizes the structure and utilizes the tilted setting of the heat pipe 200 to solve the problem of cleaning residual impurities inside the air radiator, thereby increasing the equipment life and reducing maintenance costs; by suspending the heat pipe 200, the transmission of vibrations generated by fluid flow is reduced, thereby improving the stability and reliability of the equipment.

[0036] 1 to 3 , the present disclosure provides a flat plate air radiator and makes the following embodiments:

[0037] In some embodiments, a flat-plate air radiator includes a frame 100, and the frame 100 is provided with a heat dissipation assembly and multiple support members. The heat dissipation assembly includes multiple heat dissipation tubes 200 arranged in a front-to-back tilt on the frame 100, and the two ends of the multiple heat dissipation tubes 200 are respectively a collecting end and a non-collecting end, and the non-collecting end is higher than the collecting end. It should be noted that the multiple heat dissipation tubes 200 form a tube bundle, and the liquid outlet end and the liquid inlet end of the heat dissipation tube 200 are both arranged on the same side, that is, the collecting end, wherein the two heat dissipation tubes 200 are interconnected at the non-collecting end. It can also be understood that the collecting end is the side where the liquid inlet ends of the multiple heat dissipation tubes 200 are connected to the main pipe 600 and the side where the liquid outlet end of the heat dissipation tube 200 is connected to the liquid outlet pipe. In the present disclosure, the liquid inlet end and the liquid outlet end of the heat dissipation tube 200 are arranged on the same side. In Figure 1, the front end is lower than the rear end, and the heat pipe 200 forms a specific angle from front to back. The inclination angle of the heat pipe 200 ranges from 4 to 5 degrees. Multiple support members are arranged on the frame 100 at intervals in a front-to-back tilt. The support members are configured to support the middle parts of multiple heat pipes 200. The top of the frame 100 is provided with multiple fans arranged at intervals.

[0038] Since the heat dissipation tube 200 is arranged at an angle, when cleaning, welding slag, oil stains and other residues are discharged from the heat dissipation tube 200 by gravity along with the water flow. Therefore, during the internal pickling before delivery and the operation and maintenance cleaning, it can effectively ensure that the impurities and acid residues inside the tube bundle of the heat dissipation tube 200 are efficiently emptied, and the internal acid circulation and alkali neutralization are completed with minimal water resources and time.

[0039] Specifically, the support member includes a support plate 300 and a support pad 400. The support plate 300 is provided with a plurality of support holes for the heat pipe 200 to pass through. The support pad 400 is provided with an inclined surface consistent with the inclination angle of the heat pipe 200, and the bottom of the support plate 300 is located on the inclined surface. It can be seen that the thickness of the support pad 400 gradually becomes thicker from front to back, so that the multiple support plates 300 are arranged tilted from front to back accordingly. The support pad 400 can adjust the inclination of the support plate 300, which is convenient for setting the support plate 300. During installation, the support pad 400 is first installed in an arrangement of different thicknesses, and then the support plate 300 is installed. The multiple support plates 300 are arranged tilted from front to back accordingly. Otherwise, the height of each support plate 300 needs to be carefully measured separately, and the installation is more complicated. The support pad 400 can be fixed to the frame 100 with bolts.

[0040] The support pad 400 can be made of plastic material, specifically ABS material. ABS is a polymer material with high strength, good toughness and easy processing and molding. It mainly contains resin as the main component. Resin refers to plastic. ABS has high gloss and excellent mechanical properties, and its impact strength is excellent. ABS has excellent wear resistance and good dimensional stability. The mechanical properties of ABS are greatly affected by temperature.

[0041] In some other embodiments, the support plate 300 can be directly fixed to the left and right sides of the frame 100 by screws without providing the support pad 400, which increases the difficulty of installation.

[0042] Furthermore, the frame 100 is also provided with a plurality of support tubes 500 arranged side by side with the heat dissipation tubes 200. The support tubes 500 are fixedly connected to the heat dissipation assembly, that is, the heat dissipation assembly is mainly supported by the support tubes 500 and arranged on the frame 100. The heat dissipation assembly may also include tube fins. The support tubes 500 are fixedly connected to the support plate 300. There is a gap between the support hole and the heat dissipation tube 200. Under normal circumstances, the heat dissipation tube 200 is not in direct contact with the support plate 300. After high-temperature expansion, it can be interference fit with the support hole, which also plays a certain supporting role. The tube bundle of the heat dissipation tube 200 is mainly in a suspended state. The heat dissipation tubes 200 of the tube bundle involved in heat exchange are fixed to the frame 100 through the support tubes 500 and are not in direct contact with the frame 100. The tube fins and the weight of the tube bundle involved in heat exchange are fixed as a whole by the support tubes 500 and the frame 100. No fluid passes through the interior of the support tubes 500 and does not participate in heat exchange. In this way, the vibration generated by the fluid passing through the heat dissipation tubes 200 will not be transmitted to the frame 100, thereby ensuring the overall stability of the equipment.

[0043] The frame 100 has a through-hole through which the heat pipe 200 passes. A gap exists between the heat pipe 200 and the through-hole, so that the ends of the heat pipe 200 do not directly contact the frame 100 and remain suspended. This prevents vibrations generated by the fluid passing through the heat pipe 200 from being transmitted to the frame 100, thereby ensuring the overall stability of the device.

[0044] The support tubes 500 are arranged in two rows, one on each side of the heat pipes 200, to provide better support. The support tubes 500 are evenly spaced on the frame 100. In other embodiments, the support tubes 500 may be arranged in a circular pattern around the heat pipes 200 to provide better support and achieve the purpose of suspending the tube bundle. This disclosure does not specifically limit the arrangement or number of the support tubes 500.

[0045] The water inlet of the heat pipe 200 is connected to the main pipe 600, which is provided on the frame 100. The water outlet of the heat pipe 200 is connected to the liquid outlet pipe. The main pipe 600 and the liquid outlet pipe can also support the heat pipe 200.

[0046] As a further improvement, the frame 100 is provided with a plurality of support parts 700 at the bottom thereof, configured to support the frame 100 so that the frame 100 is in a suspended state. The support parts 700 include support legs, the number of which is set according to the length of the frame 100.

[0047] During cleaning and maintenance, the present invention uses minimal water resources to drain internal liquids to the maximum extent possible, remove scale and other deposits, minimize acid residues, and keep the cooling channels free of mineral deposits, which can greatly improve efficiency, save energy, extend the service life of the equipment, and save production time and costs. The suspended heat pipe 200 can block the transmission of fluid vibrations to the frame 100, maintaining the overall stability of the equipment.

[0048] The above specifically describes the preferred embodiments of the present disclosure, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present disclosure. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application. Industrial Applicability

[0049] The above solution can effectively ensure that impurities and acid residues inside the heat dissipation tube bundle are efficiently emptied during internal pickling before shipment and during operation and maintenance cleaning, and complete internal acid circulation and alkali neutralization with minimal water resources and time, thereby extending equipment life and reducing maintenance costs.
