Description

Technical Field

[0001] This utility model relates to the technical field of special transformers, specifically a self-cooling energy-saving special transformer. Background Technology

[0002] Transformers with special purposes are generally called special transformers. In addition to converting AC voltage, transformers have various other uses, such as changing the frequency of power supply, power supply for rectifier equipment, power supply for welding equipment, power supply for electric furnaces, or as voltage transformers and current transformers. Because the working conditions and load conditions of these transformers are different from those of general transformers, they cannot be calculated using the calculation methods for general transformers.

[0003] However, existing transformers typically rely on natural air cooling for heat dissipation during operation, which cannot quickly cool the transformer. As a result, the internal temperature of the transformer remains high during prolonged operation. Therefore, this application provides a self-cooling structure energy-saving special transformer to meet the requirements. Utility Model Content

[0004] The purpose of this invention is to provide a self-cooling, energy-saving special transformer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cooling structure energy-saving special transformer, including a transformer body, with fixing frames fixed on both sides of the lower part of the transformer body, mounting holes opened on the upper part of the fixing frames, heat dissipation boxes fixed on both sides of the transformer body, fixing holes opened on one side of the heat dissipation boxes, a dustproof plate installed on one side of the heat dissipation boxes, a fixing bolt passing through one side of the dustproof plate, and a cooling mechanism provided inside the heat dissipation boxes;

[0006] The cooling mechanism includes a support plate, finned tubes, a liquid inlet, a liquid outlet, connecting pipes, and a fan. The support plate is installed inside the heat sink, and the finned tubes are installed inside the support plate. A liquid inlet is provided on the lower side of one side of the support plate, and a liquid outlet is provided on the upper side of one side of the support plate. Connecting pipes are installed on both sides of the support plate, and fans are installed on both sides of the heat sink.

[0007] Preferably, the fixing frame is symmetrically arranged around the central axis of the transformer body, and the fixing frame is used in conjunction with the mounting hole.

[0008] Preferably, the dustproof plate is threadedly connected to the heat sink via fixing bolts, and the dustproof plate matches the size of the heat sink.

[0009] Preferably, the finned tubes are evenly distributed on the inner side of the support plate, and the finned tubes are connected to the connecting tubes.

[0010] Preferably, the fan is symmetrically arranged with respect to the central axis of the heat sink, and the fan is arranged correspondingly to the finned tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This self-cooling energy-saving special transformer, through the use of a cooling mechanism, connects to the cooling oil inside the transformer body via an inlet and outlet, allowing the cooling oil to circulate inside the finned tubes. The finned tubes, with their finned design, effectively increase the heat dissipation area, thereby improving heat transfer efficiency. This ensures that the heat generated by the transformer body during operation can be quickly and effectively dissipated to the surrounding environment, ensuring that the transformer body temperature remains within a safe range and preventing performance degradation or damage caused by overheating. Simultaneously, the fan accelerates air circulation, further improving cooling efficiency.

[0013] 2. This self-cooling energy-saving special transformer, through the setting of heat dissipation box, fixing holes, dustproof plate and fixing bolts, the dustproof plate can reduce the dust in the air entering the heat dissipation box, thereby avoiding dust adhering to the surface of the finned tube and affecting the heat dissipation effect of the finned tube.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 This utility model provides a technical solution: a self-cooling structure energy-saving special transformer, including a transformer body 1, with fixing brackets 2 fixed on both sides of the lower part of the transformer body 1. The fixing brackets 2 are symmetrically arranged around the central axis of the transformer body 1. The fixing brackets 2 are used in conjunction with the mounting holes 3. The fixing brackets 2 can stably install and fix the transformer body 1, thereby ensuring the stability of the transformer body 1. The mounting holes 3 are opened on the upper part of the fixing brackets 2. Heat dissipation boxes 4 are fixed on both sides of the transformer body 1. The fixing hole 5 is opened on one side of the heat dissipation box 4. A dustproof plate 6 is installed on one side of the heat dissipation box 4. A fixing bolt 7 passes through one side of the dustproof plate 6. The dustproof plate 6 is threadedly connected to the heat dissipation box 4 through the fixing bolt 7. The size of the dustproof plate 6 matches that of the heat dissipation box 4. The dustproof plate 6 can reduce the entry of dust in the air into the interior of the heat dissipation box 4, thereby avoiding dust adhering to the surface of the finned tube 802 and affecting the heat dissipation effect of the finned tube 802. A cooling mechanism 8 is provided inside the heat dissipation box 4.

[0021] Please see Figure 3-4 The cooling mechanism 8 includes a support plate 801, finned tubes 802, a liquid inlet 803, a liquid outlet 804, a connecting pipe 805, and a fan 806. The support plate 801 is installed inside the heat sink 4. The finned tubes 802 are installed inside the support plate 801. The liquid inlet 803 is located on the lower side of one side of the support plate 801, and the liquid outlet 804 is located on the upper side of one side of the support plate 801. The finned tubes 802 are evenly distributed on the inner side of the support plate 801. The finned tubes 802 are connected to the connecting pipe 805. The finned design of the finned tubes 802 can effectively increase the cooling capacity. The heat dissipation area is increased, thereby improving the heat transfer efficiency. This allows the heat generated by the transformer body 1 during operation to be quickly and effectively dissipated into the surrounding environment, ensuring that the temperature of the transformer body 1 remains within a safe range and preventing performance degradation or damage caused by overheating. Connecting pipes 805 are installed on both sides of the support plate 801, and fans 806 are installed on both sides of the heat dissipation box 4. The fans 806 are symmetrically arranged around the central axis of the heat dissipation box 4, and the fans 806 are correspondingly arranged with the finned tubes 802. The fans 806 work together to accelerate air circulation and further improve cooling efficiency.

[0022] Working principle: When using this self-cooling energy-saving special transformer, first connect the external power supply, then fix the transformer body 1 with the fixing frame 2. During the operation of the transformer body 1, the cooling oil inside the transformer body 1 is connected through the liquid inlet 803 and the liquid outlet 804, allowing the cooling oil to circulate inside the finned tube 802. Turn on the fan 806 to accelerate air circulation. The finned tube 802, with its finned design, can effectively increase the heat dissipation area, allowing the heat generated by the transformer body 1 during operation to be quickly and effectively dissipated to the surrounding environment, ensuring that the temperature of the transformer body 1 remains within a safe range and preventing performance degradation or damage due to overheating. When not using the device, disconnect the external power supply. The fan 806 is model FP-108EX-S1-S. This completes the operation of the self-cooling energy-saving special transformer.
