Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a high-frequency transformer. Background Art

[0002] Transformers are magnetic components commonly used in electrical equipment. They utilize the principle of electromagnetic induction to convert and adjust voltage within the applicable range of the equipment. High-frequency transformers are power transformers operating at frequencies exceeding medium frequencies. They are primarily used in high-frequency switching power supplies and are their primary component. High-frequency transformers primarily consist of a bobbin, a magnetic core, a primary coil, and a secondary coil. When alternating current flows through the primary coil, an alternating magnetic flux is generated in the core, inducing a current in the secondary coil.

[0003] Transformers generate heat during operation. This heat primarily comes from two sources: iron loss, which is the heat generated by the loss of eddy currents in the transformer core; and heat generated by the load current flowing through the transformer windings, which is proportional to the square of the current. This heat must be dissipated promptly to prevent damage to the transformer. Existing technologies typically incorporate aluminum alloy heat sinks inside the transformer, on the transformer core, or by adding fans to the power supply for cooling. This structure increases the size of the transformer, increases material and labor costs during the transformer production process, and increases the size and cost of the power supply. Furthermore, these structures suffer from low mechanical strength, a short lifespan, poor heat dissipation, and low energy conversion efficiency.

[0004] Therefore, the technical problem to be solved by the present invention is that the high-frequency transformer in the prior art has low mechanical strength, short lifespan, poor heat dissipation effect and low energy conversion efficiency. Utility Model Content
