DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects of the present application more clearly understood, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0026] Based on this, the problem that the fixing method of the traditional cooling fin is relatively cumbersome and is not easy to disassemble and replace, which is not conducive to daily maintenance work, can be improved. The present application provides the following solutions.

[0027] Please refer to Figures 1 to 4 The present application provides a transformer sheet-type radiator, which comprises a transformer body 10, a radiator body 20, a limiting assembly 30 and a plurality of buckling assemblies 40.

[0028] The limiting component 30 includes multiple side plates 31 and multiple limiting blocks 32. The side plates 31 are disposed on the transformer body 10, and the limiting blocks 32 are disposed on the radiator body 20. The side plates 31 are slidably mounted on the limiting blocks 32 through the opening of the limiting port 311. The multiple side plates 31 are attached to the side walls on both sides of the radiator body 20.

[0029] The fastening assembly 40 includes a hook 41, a buckle 42, and a latch 43. The hook 41 is disposed on the side plate 31, the latch 43 is hinged to the limiting block 32, one end of the buckle 42 is rotatably disposed on the latch 43, and the other end is fastened to the hook 41 of the hook 41.

[0030] As can be seen from the above, when installing the radiator, move the radiator and align the limiting block 32 with the limiting port 311, so that the limiting block 32 slides on the side plate 31 through the limiting port 311. The side walls on both sides of the radiator body 20 are in contact with the multiple side plates 31, making it less prone to shaking. Rotate the buckle 43 towards the hook 41, and the buckle ring 42 moves towards the hook 41. Flip the buckle ring 42 so that the free end of the buckle ring 42 is placed at the hook 41. Then rotate the buckle 43 away from the hook 41, and the buckle ring 42 moves away from the hook 41 so that the buckle ring 42 abuts against the side wall at the hook 41, completing the installation and ensuring a stable fixation effect. When it is necessary to disassemble the radiator, the fastening assembly 40 can be opened by rotating the buckle 43 and the buckle ring 42, and the radiator can be moved to achieve the purpose of disassembling the radiator. Therefore, the setting of the limiting assembly 30 and the fastening assembly 40 enables the radiator to be installed on the transformer stably and conveniently.

[0031] Optionally, in some embodiments, please refer to Figure 2 The hinge end of the buckle 42 is located on the side of the hook 43 away from the hinge end.

[0032] With this configuration, the hinge end of the buckle 42 is located on the side of the latch 43 that is away from the hook 41. This allows the user to control the movement of the hinge end of the buckle 42 by rotating the latch 43, thereby controlling the range of rotation of the free end of the buckle 42. As a result, the user can install and fix the radiator body 20 by rotating the latch 43 and the buckle 42, making the operation simple and convenient.

[0033] Optionally, in some embodiments, please refer to Figure 2 The buckle 43 is provided with a rotating handle 44.

[0034] This design allows the handle 44 to be positioned so that it is convenient for staff to rotate the buckle 43.

[0035] Optionally, in some embodiments, please refer to Figures 1 to 4The radiator body 20 includes a plurality of heat sinks 21 and oil pipes 22, with the plurality of oil pipes 22 symmetrically arranged at the top and bottom of the heat sinks 21.

[0036] With this configuration, the radiator body 20 is in the shape of a metal plate and is fixed to the transformer body 10 by heat sink 21, which significantly increases the heat dissipation area of ​​the transformer. The high-temperature oil passes through the oil pipe 22 and is cooled by multiple heat sinks 21, so that the heat can be dissipated as much as possible, thereby achieving the heat dissipation effect.

[0037] Optionally, in some embodiments, please refer to Figures 1 to 3 The transformer body 10 is provided with a limiting plate 11, and the limiting plate 11 is provided with a plurality of limiting grooves 111, which are attached to the side walls on both sides of the heat sink 21.

[0038] With this configuration, after the radiator body 20 is fixed, the limiting groove 111 is attached to the side walls on both sides of the heat sink 21 to achieve the limiting effect. When the transformer is put into operation in an earthquake-prone area, the heat sink 21 is unlikely to shake during daily use.

[0039] Optionally, in some embodiments, please refer to Figures 1 to 4 The oil pipe 22 is provided with flanges 221 at both ends, and the flanges 221 are provided with multiple fixing holes 222.

[0040] With this configuration, the oil pipe 22 can be connected to other corresponding pipes through the flange 221 and multiple fixing holes 222 on the flange 221, which facilitates the flow and heat dissipation of oil.

[0041] Optionally, in some embodiments, please refer to Figure 4 The radiator body 20 also includes multiple connecting plates 23, and multiple heat sinks 21 are disposed on the connecting plates 23.

[0042] With this configuration, the heat sink 21 can be fixedly mounted on the connecting plate 23 by welding, which provides a good fixing effect and makes it difficult for the heat sink 21 to shake or shift during daily transportation or use.

[0043] Optionally, in some embodiments, please refer to Figures 1 to 4 The connecting plate 23 has pads 24 at both ends. One side of the pad 24 is attached to the side plate 31, and the other side is connected to the heat sink 21.

[0044] With this configuration, the pad 24 is elastic. Since the heat sink 21 is prone to thermal expansion and contraction during daily use, the elastic pad 24 between the heat sink 21 and the side plate 31 can effectively reduce the probability of loosening between the side plate 31 and the heat sink body 20.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
