Spiral plate type strong oil-water cooler for YSL type transformer

Abstract

The invention discloses a spiral plate type strong oil-water cooler for a YSL type transformer, which comprises a box body and a dirt removing mechanism, wherein an oil inlet pipe is arranged on the side surface of one side of the box body, a first spiral pipe is arranged at the position, which is in the box body, of the oil inlet pipe, an oil outlet pipe is arranged at the other end of the first spiral pipe, a water inlet pipe is arranged on the side surface of the side, which is away from the oil inlet pipe, of the box body, a second spiral pipe is arranged in the position, which is in the box body, of the water inlet pipe, the first spiral pipe and the second spiral pipe are oval, a water outlet pipe is arranged at the other end of the second spiral pipe, and the side surfaces of the adjacent sides of the first spiral pipe and the second spiral pipe are each provided with a plurality of outwards-protruding semicircular grooves. The oil-water cooler is simple in structure and reasonable in design, dirt in the oil pipe and the water pipe is convenient to clean, the situation that dirt is formed in the oil pipe and the water pipe to cause blockage and affect the circulation efficiency of oil and water is prevented, the cooling effect is guaranteed, meanwhile, the contact area of the oil and water is increased, and the cooling effect is improved.

Description

technical field [0001] The invention belongs to the technical field of water cooling equipment, and in particular relates to a spiral plate type strong oil-water cooler for a YSL transformer. Background technique [0002] With the sustained, healthy and rapid development of my country's economy, the demand for electricity continues to grow rapidly. The rapid development of China's electric power construction has driven the development of China's transformer manufacturing industry. Transformers are devices that transform AC voltage, alternating current and impedance. When the primary coil passes through When AC current is applied, AC magnetic flux is generated in the iron core (or magnetic core), which induces voltage (or current) in the secondary coil. At present, the spiral plate type strong oil-water cooler used in transformers. [0003] However, after long-term operation of the spiral plate type strong oil-water cooler, the impurities in the oil body and water body are eas...

AI Technical Summary

Problems solved by technology

[0003] However, after long-term operation of the spiral plate type strong oil-water cooler, the impurities in the oil body and water body are easy to form dirt inside the pipeline, which affects the normal circulation of the oil body and water body to a certain extent, and reduces the cooling efficiency. The contact surfaces between the tubes are arc surfaces, and the contact area is limited, resulting in limited heat transfer
