Description

Technical Field

After the transformer is built in, the space margin is small, and the heat dissipation effect of the transformer is not good. When the existing transformer dissipates heat, in order to prevent rainwater from entering, a grille-type strip air inlet is redundantly used, and a rain shielding eyebrow structure is arranged on the outside, such as CN202021193217.6, a box-type transformer that is convenient for heat dissipation, including a box-type transformer body, a heat dissipation box is arranged at the upper end of the box-type transformer body, and a heat dissipation hole is arranged at the side end of the heat dissipation box, and a cover plate is arranged at the upper end of the heat dissipation hole, and a base is arranged at the lower end of the box-type transformer body, and a box door is arranged at the front end of the box-type transformer body;

[0004] Such an air inlet has a small air intake volume, poor heat dissipation, and is easy to be blocked. When dissipating heat, an ordinary fan is used for heat dissipation, but the heat dissipation effect is poor. Utility Model Content
