Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a reinforcement structure for an oil-coated finned radiator. Background Technology

[0002] Plate radiators are crucial heat exchange devices in transformers. They form oil channels through finned assemblies, utilizing the circulation of transformer oil within the fins to dissipate the heat generated during transformer operation into the air, thus ensuring the safe and stable operation of the transformer. Traditional plate radiators typically consist of upper and lower oil manifolds and welded fins. Their performance directly affects the transformer's heat dissipation efficiency and lifespan. With the increase in transformer capacity and voltage levels, the requirements for radiator heat dissipation capacity and structural strength have increased. Traditional radiators rely on simple welded frames and lack three-dimensional reinforcement design, resulting in poor overall structural rigidity. They are unable to withstand the vibration and thermal stress during transformer operation, making them prone to fin deformation or connection point cracking, thus reducing their service life. Utility Model Content

Detailed Implementation

[0021] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] The embodiments provided by this utility model are as follows: Figures 1-5 As shown, a reinforcement structure for an oil-cooled finned radiator includes several finned assemblies 10. A horizontal first reinforcement plate 20 is fixedly installed at both the upper and lower ends of each finned assembly 10. Several fixing holes 30 are provided on the first reinforcement plate 20. The finned assemblies 10 are inserted into the fixing holes 30. Reinforcing components 40 are fixedly installed on the fixing holes 30, and the finned assemblies 10 are inserted into the reinforcing components 40. The reinforcing components 40 are used to clamp the finned assemblies 10. Vertical second reinforcement plates 50 are fixedly installed at both the front and rear ends of each finned assembly 10. A first oil collecting pipe 60 and a second oil collecting pipe 70 are fixedly connected to the upper and lower ends of each finned assembly 10. A reinforcement base 80 is provided below each finned assembly 10. Several second oil collecting pipes 70 are fixedly installed on the reinforcement base 80. Several first reinforcing ribs 90 are fixedly installed at the bottom of the reinforcement base 80.

[0023] Hot oil generated during transformer operation flows out from the top of the oil tank and first enters the first oil collecting pipe 60, which is connected to the upper end of the heat sink assembly 10. Here, the oil is initially distributed, preparing to flow into each heat sink of the heat sink assembly 10. At this time, the horizontally positioned first reinforcing plate 20 firmly fixes the upper end of the heat sink assembly 10 through its fixing holes 30 and reinforcing components 40, preventing oil flow impact or thermal expansion from causing misalignment of the heat sink assembly 10. The hot oil flows dispersed from the first oil collecting pipe 60 into the interior of each heat sink, flowing slowly in the narrow channels of the heat sink, while simultaneously conducting heat through the surface of the heat sink to the air for cooling. During this process, the vertically positioned second reinforcing plates 50 at the front and rear ends of the heat sink assembly 10 provide restraint, preventing the heat sink assembly 10 from shifting forward under oil pressure or external vibration. After shaking to ensure unobstructed flow, the cooled oil collects from the lower end of the heat sink assembly 10 into the second oil collection pipe 70, and finally returns to the transformer tank to complete the circulation. The second oil collection pipe 70 is fixed to the reinforcing base 80 below. The reinforcing base 80 enhances its load-bearing capacity through the first reinforcing rib 90 at the bottom, effectively dispersing the weight of the oil and operating stress, and preventing leakage from the second oil collection pipe 70 or connection points. Throughout the oil circulation process, the reinforcing structure always provides multi-dimensional mechanical constraints. Vertical displacement is suppressed by the first reinforcing plate 20 and the reinforcing component 40 in the vertical direction, and lateral deformation is resisted by the second reinforcing plate 50 in the front-back direction. The overall load is borne by the reinforcing base 80 and the first reinforcing rib 90 at the bottom. This coordinated support ensures that the radiator maintains structural integrity under long-term operation, temperature changes, or slight vibrations.

[0024] Preferably, the reinforcement component 40 includes two reinforcement members 41, which are respectively fixedly disposed on the left and right sides of the fixing hole 30. The reinforcement members 41 are provided with U-shaped grooves 42, and the two U-shaped grooves 42 are arranged opposite to each other. The heat sink assembly 10 is partially inserted into the U-shaped grooves 42. This design transforms the surface contact between the heat sink assembly 10 and the first reinforcement plate 20 into a line contact, allowing the heat sink assembly 10 to have a small displacement space when it expands and contracts with heat, avoiding stress concentration caused by rigid fixation, while providing effective constraint to prevent the heat sink assembly 10 from coming out of the fixing hole 30 or from wearing out during vibration.

[0025] Preferably, the reinforcement member 41 is located below the first reinforcement plate 20, and an anti-slip film 43 is attached to the U-shaped groove 42. By placing the reinforcement member 41 below the first reinforcement plate 20, the reinforcement structure is more concealed and does not affect the aesthetics of the top of the radiator or the operating space. The anti-slip film 43 attached to the U-shaped groove 42 is usually made of rubber or a high-friction coefficient composite material, which can significantly increase the static friction between the U-shaped groove 42 and the metal surface of the heat sink assembly 10, effectively preventing the heat sink assembly 10 from sliding or vibrating slightly in the groove, and further improving the stability and durability of the connection.

[0026] Preferably, the first reinforcing rib 90 includes two rhomboid reinforcing ribs and several crisscrossing strip reinforcing ribs. The two rhomboid reinforcing ribs are positioned at the center of the lower surface of the reinforcing base 80, and the several strip reinforcing ribs are evenly distributed on the lower surface of the reinforcing base 80. The use of two rhomboid reinforcing ribs at the center of the lower surface of the reinforcing base 80 provides stability and effectively disperses and transmits concentrated loads. The surrounding crisscrossing strip reinforcing ribs form a grid-like support frame. This composite structure ensures that the reinforcing base 80 has minimal deformation when bearing the weight of the radiator and oil, as well as resisting external vibrations, thus ensuring the stability of the entire radiator foundation and guaranteeing long-term operational reliability.

[0027] Preferably, a plurality of second reinforcing ribs 100 are fixedly provided on the outer side wall of the second reinforcing plate 50. The second reinforcing ribs 100 can enhance the out-of-plane stiffness and stability of the second reinforcing plate 50 itself. The second reinforcing plate 50 has a large area and is prone to bending deformation. The second reinforcing ribs 100 improve the bending resistance of the second reinforcing plate 50, enabling it to better resist the vibration generated during the operation of the heat sink assembly 10, and prevent the second reinforcing plate 50 itself from deforming and losing its restraining effect on the heat sink assembly 10.

[0028] Preferably, a number of second reinforcing ribs 100 are vertically and evenly distributed on the second reinforcing plate 50, with gaps between the second reinforcing ribs 100. The second reinforcing ribs 100 are elongated strip structures, and the main force direction of the second reinforcing ribs 100 is consistent with that of the second reinforcing plate 50, which can effectively provide support. The gaps between the ribs ensure the reinforcement effect and avoid excessive material concentration, thus achieving a balance between lightweight and high strength.

[0029] Preferably, reinforcing rods 110 are provided on the left and right sides of the heat sink assembly 10. The reinforcing rods 110 are horizontally positioned in the middle of the side of the heat sink assembly 10. The reinforcing rods 110 are fixedly connected to any heat sink in the heat sink assembly 10. The two ends of the reinforcing rods 110 are fixedly connected to the side walls of the two second reinforcing plates 50. The reinforcing rods 110 can tighten the heat sink assembly 10 and together with the first reinforcing plates 20 above and below and the second reinforcing plates 50 in front and behind, they form a three-dimensional spatial constraint frame, which enhances the overall vibration resistance of the heat sink.

[0030] Preferably, a number of second oil manifolds 70 are evenly distributed on the reinforcing base 80, so that the weight of the radiator and the oil load are more evenly transferred to the reinforcing base 80 through the second oil manifolds 70, avoiding local stress concentration, and also facilitating the layout and connection of the oil circuit, thus improving the rationality and reliability of the structure.

[0031] The reinforcement structure of this utility model for an oil-cooled finned radiator is achieved by fixing horizontal first reinforcement plates 20 at the upper and lower ends of the finned assembly 10, with several fixing holes 30 on the first reinforcement plates 20. The finned assembly 10 is inserted into the fixing holes 30, and reinforcement components 40 are fixedly installed in the fixing holes 30. The finned assembly 10 is inserted into the reinforcement components 40. Vertical second reinforcement plates 50 are fixedly installed at the front and rear ends of the finned assembly 10, and a reinforcement base 80 is installed below the finned assembly 10. Several second oil collection pipes 70 are fixedly installed on the reinforcement base 80, and several first reinforcing ribs 90 are fixedly installed at the bottom of the reinforcement base 80. This reinforcement structure enables the oil-cooled finned radiator to withstand vibration, oil pressure fluctuations, and external impacts during long-term operation, thereby ensuring the sealing of the oil circuit connection, the stability of the heat dissipation efficiency, and the overall durability of the equipment.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
