Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-frequency transformers, in particular to a fast heat dissipation high-frequency transformer. Background Art
[0002] A high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency. It is mainly used as a high-frequency switching power supply transformer in a high-frequency switching power supply. It is also used as a high-frequency inverter power supply transformer in a high-frequency inverter welding machine. When the high-frequency transformer is working, it will generate a higher temperature. When the temperature exceeds the specified temperature, the high-frequency transformer cannot work normally and needs to be cooled. Most of the current heat dissipation uses ventilation holes to discharge heat. At the same time, since the magnetic core is exposed, dust and other debris will accumulate for a long time, thereby affecting the heat dissipation effect. It is also easy to damage the magnetic core during the disassembly process. For this reason, we propose a high-frequency transformer with fast heat dissipation. Utility Model Content
