Abstract

The invention discloses a bladeless fan transformer heat dissipation device. The bladeless fan transformer heat dissipation device comprises a sealing shell, a transformer winding and a fixing structure of the transformer winding, the transformer winding and the fixing structure of the transformer winding are wrapped by the sealing shell, the sealing shell is fixedly connected with the transformerwinding and the fixing structure of the transformer winding, bladeless fans are installed on the top face and the bottom face of the sealing shell respectively, the installation directions are opposite, and a bottom-blowing top-pumping cooling mode is formed. The bladeless fan transformer heat dissipation device is novel in structural design and adopts a bladeless fan, has the advantages of low power consumption, low noise, high safety and the like of the bladeless fan, is integrated with the transformer, reduces complicated mounting processes, and is particularly effective in cooling effectdue to the fact that the fan is integrated with the transformer.

Description

technical field [0001] The invention relates to the technical field of transformer heat dissipation, in particular to a bladeless fan transformer heat dissipation device. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. [0003] Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation, or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be use...
