Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat dissipation devices, and more specifically to a heat dissipation device for a switching transformer. Background Art
[0002] A switching transformer is a special type of transformer used to transform and control voltage in power systems. The operating principle of a switching transformer is based on switching power supply technology, in which semiconductor switching devices (such as transistors or MOSFETs) are used to control the generation and elimination of magnetic fields. The switching transformer adjusts the magnitude and frequency of the voltage by periodically opening and closing these switching devices.
[0003] Since switching transformers operate at higher frequencies, they generally have higher efficiency and reduce energy losses. The higher frequency of switching transformers allows them to use smaller core and coil designs, making the entire device more compact. Switching transformers are often combined with digital control technology to achieve precise control and regulation of voltage. Compared with traditional transformers, switching transformers generally perform better under light load conditions and can provide a more stable output voltage.
[0004] The current heat dissipation method for switching transformers is generally to open heat dissipation holes on the surface of the transformer box to dissipate heat through natural wind. This type of heat dissipation not only has poor heat dissipation effect, but also has low efficiency. Under long-term use, it will affect the service life of the transformer. Moreover, during use, the heat sink often accumulates a lot of dust, affecting the use of the transformer. Utility Model Content

The heat is conducted into the interior of the fixed frame 301 through the through hole 311. The memory metal 321 shrinks due to the high temperature environment, so that the movable rod 303 pulls the connecting rod 304 to move to the left, thereby causing the slider 604 to move to the left.
