Description

[0002] A transformer is an essential power equipment in the power industry. As a supporting component of a low-loss transformer, a transformer fin radiator is mainly used for the circulating heat dissipation of an oil-immersed low-loss transformer, and dissipates the heat generated inside the transformer into the surrounding air.

[0003] The existing transformer fin radiators are mainly composed of a number of single-box radiating fins arranged between upper and lower collecting oil pipes. In the actual application process, during long-term use, dust, oil stains and other impurities will inevitably accumulate between the radiating fins of the transformer fin radiator. These impurities will adhere to the surface of the fins, forming a dirt layer, which will hinder the heat transfer, making it difficult for the heat to be effectively dissipated into the air. This will cause the heat dissipation efficiency of the radiator to decrease significantly, unable to meet the heat dissipation requirements of the transformer. Moreover, since the connecting pipes on both sides of the transformer fin radiator extend outward, there is a phenomenon of colliding with the connecting pipes during the transportation of the transformer fin radiator, resulting in damage to the connecting pipes, thus shortening the service life of the connecting pipes and affecting subsequent use. Therefore, a transformer fin radiator is proposed to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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.

[0029] Embodiment: This embodiment provides a finned radiator for a transformer. Refer to Figures 1-5 , specifically, it includes:

[0030] The first cooling box 1, the second cooling box 101 and the heat dissipation fin group 102. The heat dissipation fin group 102 is fixedly arranged between the first cooling box 1 and the second cooling box 101, and a bent pipe 103 penetrates through the heat dissipation fin group 102. Connect the oil inlet pipe of the first cooling box 1 and the oil outlet pipe of the second cooling box 101 to the oil outlet and oil inlet of the transformer respectively, so that the oil with temperature enters the first cooling box 1 through the oil inlet pipe, then penetrates through the heat dissipation fin group 102 and enters the bent pipe 103. Then the bent pipe 103 moves upward in an S shape reciprocally and enters the second cooling box 101. During this period, the oil contacts the heat dissipation fin group 102 multiple times for a long time, transferring the heat to the heat dissipation fin group 102 to diffuse the heat. A connecting plate 104 is fixedly arranged at the bottom of the second cooling box 101, and a cleaning component is arranged on the connecting plate 104. The cleaning component includes:

[0031] A moving unit, the moving unit includes a cross plate 2 and a cleaning rod 201. The cleaning rod 201 is fixedly arranged on the outer wall of the cross plate 2. There are multiple cleaning rods 201, and the multiple cleaning rods 201 are butted and inserted between the corresponding heat dissipation fins of the heat dissipation fin group 102. During use, by moving the cross plate 2 downward to drive the cleaning rod 201 to move downward, the space between the heat dissipation fin group 102 can be cleaned. When encountering the bent pipe 103, by pulling the cross plate 2 forward, the cleaning rod 201 can be driven to move forward to avoid the bent pipe 103 and continue cleaning, which is convenient to use;

[0032] A positioning unit, which is arranged on the cross plate 2 and is used to limit the use position of the cross plate 2.

[0033] The positioning unit includes a fixed block 203 and a connecting block 207. The fixed block 203 is fixedly installed on the outer wall of the cross plate 2, and a groove is opened on the outer wall of the fixed block 203. A trapezoidal clamping block 204 is movably inserted into the groove. The connecting block 207 is fixedly arranged on the outer wall of the connecting plate 104, and a positioning port 208 is opened on the outer wall of the connecting block 207. The trapezoidal clamping block 204 is butted and clamped in the positioning port 208. When the cleaning rod 201 is not in use, by moving the cross plate 2 upward, the fixed block 203 can be driven to move upward, so that the trapezoidal clamping block 204 enters the inner cavity of the connecting block 207. When the trapezoidal clamping block 204 is aligned with the positioning port 208, by moving the trapezoidal clamping block 204 into the positioning port 208, the trapezoidal clamping block 204 can be clamped in the positioning port 208, so that the fixed block 203 is restricted in the connecting block 207, fixing the position of the cleaning rod 201, reducing the phenomenon that the cleaning rod 201 loosens randomly and easily detaches from the fin radiator, causing it to fall and be lost. And there are two groups of positioning units, which are symmetrically distributed on both sides of the cross plate 2 and the connecting plate 104.

[0034] The inner wall of the groove is movably clamped with an extrusion block 206, and the extrusion block 206 is fixedly arranged on the outer wall of the trapezoidal clamping block 204. By sliding the extrusion block 206 in the groove, the moving path and moving range of the trapezoidal clamping block 204 are restricted.

[0035] The inner wall of the groove is fixedly provided with an extrusion spring 205, and the other end of the extrusion spring 205 is fixedly arranged on the outer wall of the extrusion block 206. By the driving force of the extrusion spring 205, the extrusion block 206 is pushed outwards, so that the outward moving extrusion block 206 drives the trapezoidal clamping block 204 to move outwards, and the trapezoidal clamping block 204 is stuck in the positioning port 208 and remains in this position without adjustment, further improving its limiting stability.

[0036] A handle 202 is fixedly arranged on the outer wall of the cross plate 2, which is convenient for the user to hold.

[0037] A bottom plate 302 is fixedly arranged on the top of the first cooling box 1. A protective plate 3 is arranged outside the bottom plate 302, and the protective plate 3 is movably inserted between the first cooling box 1 and the connecting plate 104. There are two groups of bottom plates 302, which are symmetrically distributed on both sides of the elbow 103 to protect the elbow 103 and reduce the damage of the elbow 103 caused by colliding with the elbow 103 during handling and transportation, so as to improve its safety.

[0038] A horizontal groove 301 is penetrated and opened on the outer wall of the protective plate 3 to ensure the heat dissipation performance.

[0039] A rectangular block 303 is fixedly arranged on the outer wall of the first cooling box 1, and a clamping rod 304 is rotatably arranged on the outer wall of the rectangular block 303. The clamping rod 304 is clamped on the outer wall of the protective plate 3. During use, by rotating the clamping rod 304 outwards, the clamping rod 304 is separated from the protective plate 3, so that the protective plate 3 is loosened, which is convenient to disassemble the protective plate 3 from the finned radiator. And when it is needed, the protective plate 3 is placed between the first cooling box 1 and the connecting plate 104, and by flipping the clamping rod 304, the clamping rod 304 is clamped on the protective plate 3, so that the protective plate 3 is installed on the finned radiator, which is convenient to choose disassembly and assembly according to needs and use flexibly.

[0040] Specifically, the working principle and operation method of the present utility model are as follows:

[0041] During use, press the trapezoidal block 204 inward through the positioning port 208, causing the trapezoidal block 204 to move backward and disengage from the positioning port 208. At this time, the user holds the handle 202 and pulls it downward. The downward movement of the handle 202 drives the cross plate 2 to move downward, causing the downward moving cross plate 2 to drive the cleaning rod 201 to move downward, so that the cleaning rod 201 rubs against the heat dissipation fin group 102 to wipe and clean the dust between the heat dissipation fin groups 102. And when the cleaning rod 201 encounters the elbow pipe 103, pull the cross plate 2 forward to drive the cleaning rod 201 to move forward, so that the cleaning rod 201 avoids the elbow pipe 103, and then continue to operate, which is convenient to use. When the cleaning rod 201 is not needed, move the cross plate 2 upward, causing the fixing block 203 to move upward and insert into the connecting block 207, so that the trapezoidal block 204 enters the inner cavity of the connecting block 207. When the trapezoidal block 204 is aligned with the positioning port 208, the pushing force of the compression spring 205 pushes the extrusion block 206 outward, causing the outward moving extrusion block 206 to drive the trapezoidal block 204 to move, so that the trapezoidal block 204 is stuck in the positioning port 208, restricting the fixing block 203 in the connecting block 207, facilitating the fixation of the position of the cleaning rod 201, reducing the random placement of the cleaning rod 201, and preventing the cleaning rod 201 from easily detaching from the finned radiator, resulting in dropping and loss.

[0042] During use, rotate the clamping rod 304 outward, causing the clamping rod 304 to move away from the protection plate 3, loosening the protection plate 3, and facilitating the removal of the protection plate 3 from the finned radiator. And when it is needed, place the protection plate 3 between the first cooling box 1 and the connecting plate 104, and flip the clamping rod 304 to make the clamping rod 304 stuck on the protection plate 3, so as to install the protection plate 3 on the finned radiator, facilitating the protection of the elbow pipe 103, reducing the phenomenon that the elbow pipe 103 is damaged due to collision during handling and transportation, which is beneficial to improving its safety, and it is convenient to choose to disassemble and install according to needs, with flexible use.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
