Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and specifically relates to a transformer with efficient heat dissipation. Background Technique

[0002] Transformers are key equipment in the power system and are used to convert electrical energy from one voltage level to another. Their working principle is based on electromagnetic induction, that is, when current passes through a coil (primary winding), a current will be induced in another coil (secondary winding) adjacent to it on the same magnetic core. Transformer fins are structural components used to enhance the heat dissipation of transformers and are usually installed on the outer surface of the transformer's oil tank. The role of the fins is to increase the surface area of the transformer, thereby improving the heat dissipation efficiency and helping the transformer dissipate heat better during operation.

[0003] The publication number CN220272269U discloses an auxiliary heat dissipation device for a transformer, including an oil-immersed transformer, a heat dissipation fin assembly, and an air-cooled auxiliary assembly. The heat dissipation fin assembly is respectively arranged around the oil-immersed transformer, and the air-cooled auxiliary assembly is respectively arranged on the top of the heat dissipation fin assembly. The heat dissipation fin assembly includes metal heat dissipation fins, concave grooves, and hollow cavities. The metal heat dissipation fins are arranged at equal distances and are welded to the casing of the oil-immersed transformer. It provides a heat dissipation mechanism with good expansion coefficient and an auxiliary cooling mechanism for the oil-immersed transformer, making the operation of the oil-immersed transformer more stable, solving the problem that during the operation of the existing oil-immersed transformer, due to the insufficient expansion coefficient of the casing, the pressure inside the transformer is relatively high, affecting the sealing performance of the transformer, and solving the problem that the existing oil-immersed transformer lacks an air-cooled auxiliary cooling and heat dissipation mechanism, resulting in low heat dissipation efficiency relying solely on oil cooling.

[0004] However, in the above solution, since the air ducts between the heat dissipation fins are of an open structure and the air inlets at the open ends on the side are larger than those at the bottom, when the exhaust fan sucks air from the air ducts, compared with the air intake at the bottom air inlet, more air enters the air ducts from the side air inlets. The exhaust fan's air extraction has a relatively low promotion effect on the air intake at the bottom of the air ducts, resulting in low air fluidity at the bottom of the air ducts and poor heat dissipation effect.

[0005] Therefore, we propose a transformer with efficient heat dissipation to solve the problems raised above. Content of the Utility Model

[0006] (1) Technical Problems to be Solved

[0007] Aiming at the deficiencies of the prior art in the above background technique, the purpose of the present utility model is to provide a transformer with efficient heat dissipation to solve the problems raised in the above background technique.

[0008] (2) Technical Solutions

[0009] To achieve the above object, the utility model is realized by the following technical solutions:

[0010] A transformer with efficient heat dissipation, including a transformer body, a plurality of heat dissipation fins are arranged on the periphery of the transformer body, a heat dissipation channel is formed between two adjacent heat dissipation fins, an air cooling mechanism is arranged at the bottom of the heat dissipation fins, and a closing plate is arranged at the open end of the side of the heat dissipation channel.

[0011] Furthermore, the air cooling mechanism includes a mounting frame and a plurality of blowing fans arranged on the mounting frame.

[0012] Furthermore, the closing plate includes a plate body adapted to the heat dissipation channel and a hinge block fixed on the outer wall of the heat dissipation fin, and the plate body is hinged to the hinge block.

[0013] Furthermore, an adjusting mechanism is arranged at the top of the heat dissipation fin. The adjusting mechanism includes an adjusting rod slidably installed above the heat dissipation fin. The adjusting rod includes two first adjusting rods arranged on the front and rear sides of the transformer body, two second adjusting rods arranged on the left and right sides of the transformer body, and a connecting rod arranged between the first adjusting rod and the second adjusting rod. Both ends of the connecting rod are respectively hinged to the first adjusting rod and the second adjusting rod, and the first adjusting rod and the second adjusting rod are sequentially connected end to end through the connecting rod;

[0014] A first gear is arranged at the top of the plate body, and first teeth meshing with the first gear are arranged on the side walls of the first adjusting rod and the second adjusting rod;

[0015] A driving motor is arranged at the top of one of the heat dissipation fins, a second gear is arranged on the rotating shaft of the driving motor, and a second tooth meshing with the second gear is arranged at the top of one of the adjusting rods.

[0016] Furthermore, guide blocks slidably connected to the opposite side walls of the adjusting rod are arranged at the top of the heat dissipation fin.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. By arranging an air cooling mechanism at the bottom of the fin, the air cooling mechanism can blow air into the air duct, improve the air fluidity between the air ducts, and thus accelerate the heat dissipation of the transformer; a closing plate is arranged outside the air duct. After the air cooling mechanism is started, the closing plate can block the side part of the heat dissipation air duct, so that the external air can only enter from the bottom of the air duct and discharge from the top, improve the overall air fluidity of the air duct, and make the heat dissipation of the air duct more uniform.

[0020] 2. When the transformer operates at low power and the air-cooling mechanism is closed, the adjustment mechanism can adjust the heat dissipation air duct from the side-closed state to the side-open state by rotating the closing plate, allowing external air to enter from the side of the heat dissipation air duct and improving the natural heat dissipation efficiency.

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5As shown in the figure, the utility model provides a transformer with efficient heat dissipation, which includes a transformer body 1. A plurality of heat dissipation fins 2 are arranged on the periphery of the transformer body 1. A heat dissipation channel is formed between two adjacent heat dissipation fins 2. An air cooling mechanism 3 is arranged at the bottom of the heat dissipation fins 2. A closing plate 4 for closing the open end on the side of the heat dissipation channel is arranged in the heat dissipation channel. An adjusting mechanism 5 for adjusting the state of the closing plate 4 is arranged at the top of the heat dissipation fins 2.

[0029] As Figure 2 shown, the air cooling mechanism 3 includes a mounting frame 31 and a plurality of blowing fans 32 arranged on the mounting frame 31. As Figure 1 , 3 and Figure 4 shown, the closing plate 4 includes a plate body 41 adapted to the heat dissipation channel and a hinge block 42 fixed on the outer wall of the heat dissipation fin 2. The plate body 41 is hinged to the hinge block 42.

[0030] When the transformer works at high power, the blowing fans 32 are started. Due to the setting of the closing plate 4, air can only enter the heat dissipation duct from the bottom air inlet of the heat dissipation duct, so as to improve the uniformity of heat dissipation in the duct. The blowing fans 32 accelerate the upward flow of air in the heat dissipation duct and improve the overall heat dissipation efficiency of the heat dissipation fins 2.

[0031] As Figure 3 and 4 shown, the adjusting mechanism 5 includes an adjusting rod arranged at the top of the heat dissipation fins 2. The adjusting rod includes two first adjusting rods 51 arranged on the front and rear sides of the transformer body 1, two second adjusting rods 52 arranged on the left and right sides of the transformer body 1, and a connecting rod 53 arranged between the first adjusting rod 51 and the second adjusting rod 52. Guide blocks 59 slidably connected to the opposite side walls of the first adjusting rod 51 and the second adjusting rod 52 are arranged at the top of the heat dissipation fins 2. Both ends of the connecting rod 53 are hinged to the first adjusting rod 51 and the second adjusting rod 52 respectively. The first adjusting rod 51 and the second adjusting rod 52 are sequentially connected end to end through the connecting rod 53;

[0032] A first gear 54 is arranged at the top of the plate body 41. First teeth 55 meshing with the first gear 54 are arranged on the side walls of the first adjusting rod 51 and the second adjusting rod 52;

[0033] A driving motor 56 (shown at the front side in the figure) is arranged at the top of one of the heat dissipation fins 2. A second gear 57 is arranged on the rotating shaft of the driving motor 56. Second teeth 58 meshing with the second gear 57 are arranged at the top of one of the adjusting rods (the first adjusting rod 51 at the front side in the figure).

[0034] The adjusting mechanism 5 can adjust the state of the closing plate 4. When the transformer operates at low power, it generates less heat. At this time, the air-cooling mechanism 3 can be turned off, and the driving motor 56 is started. For the convenience of description, the driving motor 56 rotates forward. Through the engagement of the second gear 57 and the second tooth 58, the first adjusting rod 51 is driven to move. Due to the setting of the guiding block 59, the adjusting rods all move in a direction parallel to the side wall of the transformer body 1. When the first adjusting rod 51 moves, the second adjusting rod 52 is driven to move through the connecting rod 53. When the adjusting rods move, the plate body 41 is driven to rotate on the hinge block 42 through the engagement of the first gear 54 and the first tooth 55, so that the closing plate 4 is opened to improve its natural heat dissipation efficiency; conversely, the closing plate 4 can be closed when the air-cooling mechanism 3 is turned on.

[0035] As a preferred technical solution of the present utility model: The surface of the heat dissipation fins 2 is coated with a nano heat dissipation coating to further enhance the heat dissipation efficiency of the heat dissipation fins 2.

[0036] For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations; for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
