Problems solved by technology
[0003] The traditional heat dissipation of transformers is mainly through setting air passages or oil passages in the body, and taking away heat through the circulation of gas or oil for heat dissipation. In addition, there are corresponding forced air exhaust devices or hot oil circulation heat dissipation devices, and water cooling is also used The cooling device dissipates heat. Its structure is complex, and it is difficult to manufacture and maintain. It is highly specific to the type of transformer and does not have universal applicability. The traditional heat dissipation method for transformers also uses heat sinks or fans to dissipate heat, but it is simple. The combination of the two does not achieve the ideal cooling effect

The invention discloses a heat radiator for a transformer, comprising fin-type radiators and an air blower. The heat radiator is characterized in that: at least two fin-type radiators are arranged and a plurality of the fin-type radiators are connected through connection members; an air flow channel is arranged among the plurality of the panel-type radiators; the air blower is arranged on heat radiation openings of the fin-type radiators at the outer side and an air vent of the air blower is aligned to the heat radiation openings of the fin-type radiators. The heat radiator provided by the invention is simple in structure, convenient for manufacturing and maintaining and good in heat radiation effect.
Description
technical field [0001] The invention relates to a cooling device for a transformer, in particular to a cooling device for a transformer combining a radiator and a fan. Background technique [0002] With the development and improvement of transformer technology, various large-capacity and high-voltage transformers have been designed and developed. New transformers have higher and higher requirements for heat dissipation, so a new type of heat dissipation device is required to meet their needs. [0003] The traditional heat dissipation of transformers is mainly through setting air passages or oil passages in the body, and taking away heat through the circulation of gas or oil for heat dissipation. In addition, there are corresponding forced air exhaust devices or hot oil circulation heat dissipation devices, and water cooling is also used The cooling device dissipates heat. Its structure is complex, and it is difficult to manufacture and maintain. It is highly specific to th...
