Description

Technical Field

[0001] The utility model relates to a cooling device, in particular to a transformer cooler. Background Art

[0002] During the operation of a transformer, a large amount of heat is generated. If these heats cannot be dissipated in time and effectively, it may cause the internal components of the transformer to overheat, thereby affecting its normal operation or shortening its service life.

[0003] Adopting air-cooled heat dissipation is one of the common heat dissipation methods for transformer coolers. However, currently, the blowing direction of the air-cooled part of the cooler is towards the outside of the cooler, resulting in poor cooling effect. In addition, scale will gradually accumulate on the surface of the heat dissipation component after long-term operation, seriously affecting the heat dissipation effect. And currently, the air direction of the cooler is towards the outside of the cooler, so the dust removal effect cannot be achieved.

[0004] For the above reasons, this application provides a transformer cooler, aiming to enhance the cooling effect. Summary of the Utility Model

The upper portion is relatively wide, which can smoothly split the oncoming airflow, reduce the impact of the airflow, and reduce the formation of turbulence. The lower portion is narrow and offset to one side, so that the airflow re-converges at the lower portion of the guide plate, reducing the airflow separation effect at the lower portion, so that the airflow can continue to flow smoothly, reducing air resistance and enhancing the cooling effect.
