Description

Technical Field

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

[0002] The transformer bobbin provides mechanical support for the transformer's windings, ensuring they maintain a stable shape and position during the winding process. For example, in a toroidal transformer, the bobbin allows the windings to be evenly wound around the toroidal core, preventing them from loosening or shifting. It also secures the core and ensures the accurate relative position between the core and windings, thereby improving the transformer's electromagnetic performance. The bobbin is typically made of insulating materials such as plastic or Bakelite. It insulates the windings from the core and from each other, preventing short-circuit failures. For example, in high-frequency transformers, a bobbin with good insulation can effectively reduce capacitive coupling between windings and lower high-frequency losses. However, because the bobbin is sealed, it dissipates heat poorly, which reduces the service life of the coils and transformer.

[0003] The existing transformer frame is sealed and has low heat dissipation efficiency.

[0004] For example, a transformer skeleton disclosed in the announcement number CN218886968U, the transformer skeleton in this patent includes a top plate and a bottom plate, the top plate is connected to the bottom plate through a winding column, main terminal parts and secondary terminal parts are provided on both sides of the bottom plate, a number of pins are provided at the lower ends of the main terminal parts and the secondary terminal parts, oil filling platforms are provided on both sides of the top plate, a number of U-shaped oil filling holes are provided in the oil filling platforms, a wiring groove is provided on the main terminal part, and a wire partition groove is provided below the secondary terminal part. The position of the wire partition groove can fix the direction of the wire pulling out when the wire is pulled out of the winding column, reducing the possibility of crossing with other wires. Due to the wire-releasing inclined surface provided on the wire partition groove, the wire pulling direction can be adjusted once when the wire is pulled into the wire partition groove, preventing unnecessary wear of the wire when it is pulled into the wire groove and extending the service life. However, the skeleton is sealed, which affects the operation and heat dissipation of the internal coil, which can easily lead to a short service life of the coil.

[0005] Therefore, it is necessary to invent a high-efficiency heat dissipation transformer skeleton to solve the above problems. Utility Model Content
