Abstract

The invention discloses a finned radiator of a transformer. The finned radiator comprises an oil outlet pipeline and an oil inlet pipeline and further comprises a radiator fin set formed by corrugated fins and welded to the portion between the oil outlet pipeline and the oil inlet pipeline. A plurality of U shapes which are formed at equal intervals and the same in size are bent on a steel plate and serve as the corrugated fins, U-shaped openings of every two corrugated fins are in tight butt joint to form cavities, the edges of the two sides of the bottom ends of the cavities are in butt joint in the opposite direction and then are welded, the edges of the two sides of the top ends of the cavities are in butt joint in the opposite direction and then welded, the bottom ends of the cavities are welded to the oil outlet pipeline, and the bottom end of each cavity is provided with a through hole communicated with the oil outlet pipeline. The top ends of the cavities are welded to the oil inlet pipeline, the top end of each cavity is provided with a through hole communicated with the oil inlet pipeline, every two corrugated fins of which the U-shaped openings are in butt joint form a corrugated fin set, and the radiator fin set is composed of the multiple corrugated fin sets. The finned radiator has the advantages that the delivery cycle of the transformer can be shortened, the radiating surface of the transformer is increased, and then the service life of the transformer is prolonged.

Description

A kind of transformer gilled radiator

Technical field

The present invention relates to a kind of transformer gilled radiator, belong to transformer heat dissipation technology field.

Background technology

The heat that transformer operation produces can make transformer body temperature raise, and needs heat abstractor to lower the temperature to transformer.Gilled radiator on the market, there is multiple being arranged in order and equidistant group, each group formed by two stalloy docking, the top of this sheet group is welded and communicates with fuel-displaced pipeline, bottom is welded with in-line and is communicated, the processing mode complexity of this radiator fin group, and technical requirement is high, need to have large-scale production line, and this radiator do not possess swollen contracting function.Transformer producer does not possess the production capacity of this kind of radiator, need to purchase from professional radiator producer, thus the production cost of increase transformer.

Summary of the invention

The problem existing for above-mentioned prior art, the invention provides a kind of transformer gilled radiator, increases the radiating surface of radiator, reduces production costs.

To achieve these goals, the technical solution used in the present invention is: a kind of transformer gilled radiator, comprise fuel-displaced pipeline and in-line, fuel-displaced pipeline and in-line are connected in transformer body by oil-out and oil-in respectively, also comprise the radiator fin group being formed by corrugated plate being welded between fuel-displaced pipeline and in-line, on steel plate, be bent with a plurality of equidistant and equal-sized U-shaped rear as corrugated plate, U-shaped mouthful of closed butt joint of two corrugated plates forms cavity, the top dual-side of cavity is along welding after docking in opposite directions, the bottom dual-side of cavity is along welding after docking in opposite directions, the bottom of cavity is welded in fuel-displaced pipeline, the bottom of each cavity is provided with the through hole communicating with fuel-displaced pipeline, the top of cavity is welded in in-line, and the top of each cavity is provided with the through hole communicating with in-line, and two corrugated plates of U-shaped mouthful of docking form a corrugated plate group, and described radiator fin group is made up of a plurality of corrugated plate groups.

Preferably, described oil-out and oil-in are connected in transformer body by adpting flange.

Preferably, U-shaped mouthful of joint of two corrugated plates closely welds.

Radiator in the present invention, the producer that generally produces transformer shell just possesses the condition of this kind of radiator of processing, need to, from professional manufacturer's buying, can not reduce costs and procurement cycle, and then shorten dispatching from the factory the cycle of transformer; Because this transformer gilled radiator is made up of corrugated plate, there is swollen contracting function, oil conservator need to be installed on transformer body, avoid insulating oil to make moist, thereby improved the useful life of transformer.

In figure: 1, fuel-displaced pipeline, 11, oil-out, 2, in-line, 21, oil-in, 3, corrugated plate, 31, corrugated plate group, 4, adpting flange.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in Fig. 1-Fig. 3: the present invention includes fuel-displaced pipeline 1 and in-line 2, fuel-displaced pipeline 1 and in-line 2 are connected in transformer body by oil-out 11 and oil-in 21 respectively, also comprise the radiator fin group being formed by corrugated plate 3 being welded between fuel-displaced pipeline 1 and in-line 2, steel plate bending pluralizes individual equidistant and equal-sized U-shaped as corrugated plate 3, U-shaped mouthful of closed butt joint of two corrugated plates 3 forms cavity, the top dual-side of cavity is along welding after docking in opposite directions, the bottom dual-side of cavity is along welding after docking in opposite directions, the bottom of cavity is welded in fuel-displaced pipeline 1, the bottom of each cavity is provided with the through hole communicating with fuel-displaced pipeline 1, the top of cavity is welded in in-line 2, and the top of each cavity is provided with the through hole communicating with in-line 2, and two corrugated plates 3 of U-shaped mouthful of docking form a corrugated plate group 31, and described radiator fin group is made up of a plurality of corrugated plate groups 31.

Described oil-out 11 and oil-in 21 are connected in transformer body by adpting flange 4, adopt this connected mode good connecting effect, and are easy to dismounting.

The present invention is owing to adopting the design of corrugated plate group 31, and its cavity has the swollen contracting function of expanding with heat and contract with cold along with insulating oil, also can adopt the radiator in the present invention even if the full-sealed transformer of oil conservator is not installed.

U-shaped mouthful of joint of two corrugated plates 3 closely welds, and adopts the mode of welding, easy to process, simple to operate, realizes U-shaped tight-lipped leakproof fit object.

The present invention is in the time dispelling the heat work, transformer body is immersed in insulating oil, transformer heat is by the thermal convection of insulating oil, upwards flow into oil-in 21 by transformer body, the cavity forming through each corrugated plate group 31 is again downwards through oil-out inflow transformer body, heat, by spreader surface radiation, distributes through cross-ventilation, reaches heat radiation object.
