Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a novel transformer with high-efficiency heat dissipation. Background Art

[0002] In the existing transformers, independent metal sheets are placed on each side of the magnetic core. This design leads to complicated production processes. Each metal sheet needs to be processed and installed separately, which increases production costs and time. Since the two metal sheets are independent individuals, they may have problems such as inaccurate alignment and loose contact during installation and fixation, which affects the thermal conductivity. At the same time, the metal heat sink is not in direct contact with the wires of the coil, resulting in the heat generated by the wires cannot be effectively transferred to the metal heat sink, resulting in poor heat dissipation of the wires. Poor heat dissipation of the wires will cause the wire temperature to rise, which in turn affects the overall performance and life of the transformer, and may even cause safety problems. Due to the poor heat dissipation of the wires, the transformer may require additional heat dissipation measures when working, such as adding fans or heat sinks, which further increases costs and complexity.

[0005] Preferably, the first heat dissipation portion includes a first heat dissipation base and a first arc-shaped limiting portion fixed on the top of the first heat dissipation base, the inner edge of the first arc-shaped limiting portion is fixed to the left end of the winding drum body, and the first arc-shaped limiting portion is directly opposite to the left side of the wire. The inner edge of the first arc-shaped limiting portion is fixed to the left end of the winding drum body. Such a design enables a stable connection to be formed between the first heat dissipation portion and the winding drum body. At the same time, the first arc-shaped limiting portion is directly opposite to the left side of the wire. Based on the direct contact heat conduction of the winding drum body, such a layout helps to effectively conduct the heat generated on the left side of the wire to the entire first heat dissipation portion, further improving the heat dissipation efficiency.

[0006] Preferably, the lower half of the first heat dissipation base is bent and extended in the horizontal direction and is formed with a first horizontal positioning plate. Such a design enables the first heat dissipation base to be more firmly positioned at a desired position during installation, thereby improving the stability and reliability of the entire heat dissipation structure.

[0007] Preferably, first positioning holes are formed in the first horizontal positioning plate. The provision of these first positioning holes facilitates the connection and fixation between the first heat dissipation base and other components, making the installation and disassembly processes of the entire heat dissipation structure more convenient.

The inner edge of the second arc-shaped limiting part is fixed to the right end of the wire winding cylinder, and the second arc-shaped limiting part faces the right side of the wire. Similarly, the inner edge of the second arc-shaped limiting part is fixed to the right end of the wire winding cylinder. Such a design enables a firm connection to be formed between the second heat dissipation part and the wire winding cylinder. At the same time, the second arc-shaped limiting part faces the right side of the wire. Based on the direct contact heat conduction of the wire winding cylinder, such a layout helps to effectively conduct the heat generated on the right side of the wire to the entire second heat dissipation part, further improving the heat dissipation efficiency.

[0009] Preferably, the lower half of the second heat dissipation base extends horizontally and bends to form a second horizontal positioning plate. Similarly, such a design enables the second heat dissipation base to be more stably positioned at the required position during installation, improving the stability and reliability of the entire heat dissipation structure.

[0010] Preferably, second positioning holes are formed in the second horizontal positioning plate. The provision of these second positioning holes facilitates the connection and fixation between the first heat dissipation base and other components, making the installation and disassembly processes of the entire heat dissipation structure more convenient.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the originally scattered two independent metal heat dissipation fins are integrated into a part of the base frame, namely the first heat dissipation part and the second heat dissipation part, reducing the steps of separate treatment and installation, simplifying the production process, and effectively reducing the production cost and time; further, the integrated heat dissipation part design ensures the alignment accuracy with the magnetic core and the wire, improves the contact tightness, thereby enhancing the heat conduction efficiency. This design avoids the problem of reduced heat conduction effect caused by inaccurate alignment or loose contact; further, the wire is directly arranged in the outer installation area and contacts the outer side surface of the wire winding cylinder. Such a design enables the heat generated by the wire to be more effectively transferred to the heat dissipation part, significantly improving the heat dissipation effect of the wire. Good heat dissipation performance helps to control the wire temperature, extend the service life of the transformer, and improve its operating stability and safety; further, due to the improvement of the heat dissipation efficiency, the transformer may no longer require additional heat dissipation measures, such as adding a fan or heat dissipation fins, during operation, which not only reduces the cost but also reduces the complexity and maintenance requirements of the system.

The wire 2 is located in the outer installation area 34 and contacts the outer side surface of the winding cylinder body 31, and the magnetic core 1 passes through the inner installation area 35.

[0023] In this embodiment, it should be noted that the two originally separate independent metal heat sinks are integrated into a part of the base frame 3, that is, the first heat dissipation part 32 and the second heat dissipation part 33, which reduces the steps of separate processing and installation, simplifies the production process, and effectively reduces the production cost and time. Further, the integrated heat dissipation part design ensures the alignment accuracy with the magnetic core 1 and the wire 2, improves the contact tightness, and thus enhances the heat conduction efficiency. This design avoids the problem of reduced heat conduction effect caused by inaccurate alignment or loose contact. Further, the wire 2 is directly arranged in the outer installation area 34 and contacts the outer side surface of the winding cylinder body 31. Such a design enables the heat generated by the wire 2 to be more effectively transferred to the heat dissipation part, significantly improving the heat dissipation effect of the wire 2. Good heat dissipation performance helps to control the temperature of the wire 2, extend the service life of the transformer, and improve its operation stability and safety. Further, due to the improvement of the heat dissipation efficiency, the transformer may no longer require additional heat dissipation measures, such as adding a fan or a heat sink, during operation, which not only reduces the cost, but also reduces the complexity and maintenance requirements of the system.

Such a design makes a firm connection between the first heat dissipation part 32 and the winding cylinder body 31. At the same time, the first arc-shaped limiting part 322 faces the left side of the wire 2. Based on direct heat conduction through the winding cylinder body 31, such a layout helps to effectively conduct the heat generated on the left side of the wire 2 to the entire first heat dissipation part 32, further improving the heat dissipation efficiency.

The inner edge of the second arc-shaped limiting part 332 is fixed to the right end of the wire winding cylinder 31, and the second arc-shaped limiting part 332 faces the right side of the wire 2.

[0031] In this embodiment, it should be noted that, similarly, the inner edge of the second arc-shaped limiting part 332 is fixed to the right end of the wire winding cylinder 31. Such a design enables a firm connection to be formed between the second heat dissipation part 33 and the wire winding cylinder 31. At the same time, the second arc-shaped limiting part 332 faces the right side of the wire 2. Based on the direct heat conduction of the wire winding cylinder 31, such a layout helps to effectively conduct the heat generated on the right side of the wire 2 to the entire second heat dissipation part 33, further improving the heat dissipation efficiency.

[0032] In one embodiment, the lower half of the second heat dissipation base 331 extends horizontally and bends to form a second horizontal positioning plate 3311.
