Aluminum alloy radiator applied to converter transformer

Abstract

The invention relates to an aluminum alloy radiator applied to a converter transformer. The aluminum alloy radiator comprises an oil inflow pipe, an oil return pipe, a cleaning device and a plurality of cooling sheets; each cooling sheet comprises a fin body and a plurality of fins, a containing cavity is formed in the fin body; the oil inflow pipe is connected with the cooling sheets and connected with the containing cavities; the oil return pipe is connected with the cooling sheets and connected with the containing cavities; and the cleaning device is used for cleaning the cooling sheets, and the cooling sheets are made of aluminum alloy. Compared with the prior art, the heat dissipation performance of the radiator is effectively improved, and the number of the steel radiator sheets is reduced; the aluminum alloy is light in weight, so that the aluminum alloy radiator has better structural advantages on the transformer compared with a steel radiator; the outer surface of the aluminum alloy radiator basically does not need to be coated, so that environmental pollution is reduced; the aluminum alloy inner wall does not need paint coating for corrosion prevention, so that the safety and stability of the operation of the transformer are improved; and the cleaning device is arranged to prevent impurities from adhering to the radiator to influence the radiating effect.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to an aluminum alloy radiator applied to a converter transformer. Background technique [0002] Existing transformers are abnormally affected due to excessive temperature during use, and steel radiators are usually used as radiator components on the transformer to dissipate the heat generated during the operation of the transformer into the air to control the operating temperature of the transformer. Ensure the safe and stable operation of the transformer. The radiators currently in use are usually composed of two steel pipes processed with split holes and a group of cooling fin units arranged longitudinally and parallel at equal intervals between the two steel pipes. This kind of radiator mainly has the disadvantages of heavy weight and poor heat dissipation effect. It is easy to have a lot of internal foreign matter and hydrogen production inside, which will pollute th...

The radiators currently in use are usually composed of two steel pipes processed with split holes and a group of cooling fin units arranged longitudinally and parallel at equal intervals between the two steel pipes. This kind of radiator mainly has the disadvantages of heavy weight and poor heat dissipation effect. It is easy to have a lot of internal foreign matter and hydrogen production inside, which will pollute the transformer oil and affect the safe operation of the transformer
