Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer heat dissipation structure. Background Technology

[0002] Transformers, as core components in electronic circuits that achieve power conversion and electrical isolation, are widely used in consumer electronics, communication equipment, industrial control, and smart homes. With the miniaturization, integration, and high power density of electronic devices, the size, height, and compatibility with surrounding components of transformers are subject to strict limitations, while also needing to meet the temperature rise requirements for long-term reliable operation.

[0003] Existing technologies have not addressed the heat dissipation requirements and typically employ heat sinks for cooling. However, due to limited installation space, existing heat sink structures cannot meet the installation requirements of transformers, resulting in insufficient heat dissipation and difficulty in effectively suppressing temperature rise. Utility Model Content

[0004] The main purpose of this utility model is to provide a transformer heat dissipation structure, which aims to solve the problem of insufficient heat dissipation effect of existing transformers.

[0007] At least one first heat sink is provided. The first end of the first heat sink is connected to the edge of the heat dissipation body and extends along the axial direction of the transformer. A plurality of first heat dissipation holes are provided on the first heat sink.

[0008] The second heat sink is connected to the second end of the first heat sink. The second heat sink is arranged in a U-shape and has several second heat dissipation holes.

[0018] The beneficial effects of this utility model are as follows: it improves the heat dissipation structure of the existing transformer.

[0028] One embodiment of this utility model provides a transformer heat dissipation structure, referencing... Figure 1 The heat dissipation structure is installed on the transformer, for reference. Figure 2 The heat dissipation structure includes:

[0029] The heat dissipation main body 2 is attached to the outer periphery of the transformer 1 main body;

[0030] At least one first heat sink 3 is provided. The first end of the first heat sink 3 is connected to the edge of the heat dissipation body 2, and the first heat sink 3 extends along the axial direction of the transformer 1. A plurality of first heat dissipation holes 31 are provided on the first heat sink 3.

[0031] The second heat sink 4 is connected to the second end of the first heat sink 3. The second heat sink 4 is arranged in a U-shape and has a plurality of second heat dissipation holes 41.

[0032] In this embodiment, the heat dissipation body 2 is fitted along the outer periphery of the transformer 1 body, increasing the contact area with the transformer 1 body. This allows for rapid and uniform heat transfer from the windings and core inside the transformer 1 to the heat dissipation structure, reducing local heat accumulation inside the transformer 1 and improving heat dissipation efficiency from the heat conduction source. The first heat sink 3 extends along the axial direction of the transformer 1, with its extension direction perpendicular to the PCB board plane (horizontal direction). This fully utilizes the redundant space along the axial (height direction) direction of the transformer 1, improving heat dissipation efficiency without sacrificing the installation space of the transformer 1. The second heat sink 4 further increases the surface area of ​​the heat dissipation structure, accelerating heat dissipation. Simultaneously, the U-shaped structure of the second heat sink 4 forms a heat dissipation channel, providing an airflow path to quickly remove heat from the heat sink and accelerate heat dissipation. The plurality of first heat dissipation holes 31 on the first heat sink 3 and the plurality of second heat dissipation holes 41 on the second heat sink 4 reduce the overall weight of the heat sink while promoting heat exchange between external cold air and the surface of the heat sink, further accelerating heat dissipation.

[0033] Furthermore, the transformer 1 body includes a magnetic core, which is arranged in a rectangular frame structure. The heat dissipation body 2 is configured as a rectangular frame structure adapted to the outer side of the magnetic core, and the heat dissipation body is installed on the outer side of the magnetic core. The rectangular frame structure of the heat dissipation body 2 is highly matched with the shape of the rectangular magnetic core, occupying only a width equivalent to the outer diameter of the magnetic core in the radial direction. It does not require additional horizontal or vertical expansion, thus significantly improving heat dissipation efficiency without occupying much space.

[0034] Furthermore, the heat dissipation body 2 is provided with a buckle 21 and a slot 22 for fixing. Specifically, during installation, after the heat dissipation body 2 is sleeved on the outside of the magnetic core, simply press the buckle 21 into the slot 22 to complete the installation of the heat dissipation body 2. This also ensures that the heat dissipation body 2 is completely fitted to the outside of the magnetic core, improving the installation stability of both, simplifying the operation, and improving assembly efficiency. This fixing structure does not require additional auxiliary structures. Based on the heat dissipation body 2 itself, after installation, the heat dissipation body 2 is a frame structure that is completely fitted to the magnetic core, and compared with existing screw fixing structures, it does not occupy additional space.

[0035] Furthermore, the heat dissipation main body 2 has several folded edges 23 along its edge, and the folded edges 23 abut against the surface of the magnetic core. In this embodiment, the folded edge 23 structure can press the surface of the magnetic core from above, thereby effectively limiting the heat dissipation main body 2 and making it stably attached to the surface of the magnetic core, preventing relative sliding between the two, and ensuring that the two are always attached together, which is beneficial to heat dissipation and structural stability.

[0036] Furthermore, four folded edges 23 are provided, and the four folded edges 23 are distributed at the four end corners of the heat dissipation main body 2. In this embodiment, four folded edges 23 are provided and distributed at the four end corners of the heat dissipation main body 2 to ensure uniform stress on the folded edges 23 and structural stability, simplifying the material usage. At the same time, the folded edges 23 can increase the contact area between the heat dissipation main body 2 and the magnetic core, further improving the heat dissipation efficiency.

[0037] Furthermore, two first heat sinks 3 are provided, and the two first heat sinks 3 are symmetrically distributed. The second end of each first heat sink 3 is connected to a second heat sink 4. The two first heat sinks 3 are symmetrically distributed on the edge of the heat dissipation body 2, which can evenly conduct the heat absorbed by the heat dissipation body 2 from the magnetic core to both sides along the axial direction, balance the temperature distribution in different areas inside the transformer 1, and significantly reduce the risk of local hot spots caused by insufficient heat dissipation on one side.

[0038] Furthermore, the first heat dissipation hole 31 is configured as an oblong hole. The oblong shape of the first heat dissipation hole 31, extending along the width of the first heat sink 3, enhances the overall strength of the first heat sink 3, ensures structural stability, and prevents deformation.

[0039] Furthermore, the second heat dissipation hole 41 is configured as a circular hole. A circular hole has the smallest perimeter for the same opening area, which can reduce the material occupied by the second heat sink 4 body, ensure the contact area between the second heat sink 4 body and the air, accelerate heat dissipation, and also reduce the risk of deformation of the second heat sink 4.

[0040] Furthermore, the heat dissipation body 2, the first heat sink 3, and the second heat sink 4 are configured as an integrally formed structure. This integral forming eliminates the contact thermal resistance between different components, allowing heat to be conducted and diffused more smoothly between the heat dissipation body 2, the first heat sink 3, and the second heat sink 4. This improves heat dissipation efficiency, helps the transformer 1 dissipate heat better, maintains its normal operating temperature, and enhances the performance and stability of the transformer 1.

[0041] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
