Description

Technical Field

[0001] This utility model relates to the technical field of transformer frame devices, specifically a novel transformer frame. Background Technology

[0002] As a key component of miniature transformers, the miniature transformer bobbin is mainly used to support and fix the coils, playing a crucial role in various small electronic devices. However, traditional miniature transformer bobbins have certain design flaws. Their compact winding structure makes it difficult to dissipate the heat generated by the coils during operation. Due to the lack of an effective heat dissipation structure, heat easily accumulates inside the bobbin, which not only accelerates the aging of the coil insulation material and reduces the transformer's efficiency and stability but may also cause safety hazards, seriously affecting the service life and performance of the miniature transformer.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 To be continued Figure 6 A novel transformer frame includes a winding cylinder 1, a first support plate 2, and a second support plate 3. The winding cylinder 1 is a long, hollow cylindrical body, with both ends perpendicularly connected to the first support plate 2 and the second support plate 3 to form an I-shaped main structure. The front and rear sides of the winding cylinder 1 are planar structures, and the left and right ends are arc-shaped. Multiple support ribs 4 for winding are fixedly provided at intervals on the front and rear sides of the winding cylinder 1. Several winding grooves 7 are provided on the surface of the support ribs 4 at equal intervals. Heat dissipation grooves 5 are provided on the front and rear sides of the winding cylinder 1 and between adjacent support ribs 4. A thermally conductive silicone plate 6 is fixedly provided on the bottom surface of the heat dissipation groove 5. The heat dissipation groove 5 penetrates the first support plate 2 and the second support plate 3 to form a vertical heat dissipation channel 10.

[0024] In this embodiment, as a preferred technical solution, mounting bases 8 are fixedly provided on both the left and right sides of the bottom of the second support plate 3, and wiring posts 9 are fixedly provided on the bottom of the mounting bases 8. The two mounting bases 8 protrude from the bottom surface of the second support plate 3 and form a bottom heat dissipation channel 11 with the bottom surface of the second support plate 3.

[0025] The working principle of this utility model is as follows: The core working principle of this new transformer frame is to optimize the heat dissipation path and winding structure. The winding drum 1 serves as the main body for coil winding. The supporting ribs 4 and winding grooves 7 on its front and rear sides facilitate the orderly winding of the coil and reduce the heat generated by the mutual compression of the coils. The thermally conductive silicone plate 6 inside the heat dissipation groove 5 has good thermal conductivity and can quickly conduct the heat generated by the coil to the heat dissipation groove 5. The thermally conductive silicone plate 6 can also absorb the heat inside the winding drum to assist in heat dissipation. The vertical heat dissipation channel 10 runs through the first support plate 2 and the second support plate 3, and the bottom heat dissipation channel 11 is set through the space between the mounting base 8 and the bottom surface of the second support plate 3. The two form a three-dimensional heat dissipation channel, which accelerates air convection and thus efficiently removes heat and ensures the stable operation of the transformer.

[0026] The working process of this utility model is as follows:

[0027] 1. Coil winding: The coil is wound on the support ribs 4 on the front and rear sides of the winding drum 1. The winding groove 7 is used to position and fix the coil to form a regular winding layout, which is in preparation for subsequent power-on work.

[0028] 2. Heat generation: When the transformer is energized, the coil generates heat due to the current passing through it. The heat is first transferred to the front and rear sides of the winding drum 1, which is in close contact with the coil.

[0029] 3. Heat conduction: The heat from the front and rear sides of the winding drum 1 is quickly transferred to the thermally conductive silicone plate 6 on the bottom of the heat dissipation groove 5. Due to its high thermal conductivity, the thermally conductive silicone plate 6 quickly diffuses the heat to the entire heat dissipation groove 5 area.

[0030] 4. Heat dissipation: The heat in the heat dissipation tank 5 is conducted upward through the vertical heat dissipation channel 10. At the same time, the bottom heat dissipation channel 11 promotes air flow at the bottom of the transformer frame. The air forms convection, which dissipates the heat from the vertical heat dissipation channel 10 and the bottom heat dissipation channel 11, achieving efficient heat dissipation and maintaining the normal operating temperature of the transformer.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
