Description

Technical Field

[0002] The box-type transformer is a traditional transformer designed in a box-type housing. It has small size, light weight, low noise, low loss and high reliability. It is widely used in residential areas, commercial centers, light stations, airports, factories, mines, enterprises, hospitals, schools and other places. During the use of the box-type transformer, the heating of the electrical components in the box and the exposure of the box in the outdoor environment may cause the transformer to burn out or cause explosion safety hazards. Therefore, how to dissipate heat is an important issue that needs to be solved to ensure the normal operation of the box-type transformer.

[0003] However, most current transformer boxes are equipped with exhaust fans to discharge the internal hot air or directly draw in external air to replace the internal air when cooling the interior. This method dissipates heat slowly, and the external air is easily affected by the external temperature, making the air hotter and not having good heat dissipation capacity.

[0004] Therefore, a transformer box with high heat dissipation efficiency is proposed. Utility Model Content
