Abstract
The utility model relates to an aluminum alloy radiator for a power transformer. The radiator is made of aluminum alloy so as to improve heat transfer efficiency of the radiator. The radiator adopts extrusion forming, and fins are processed between the internal and external surfaces of the aluminum radiator and are vertical to the internal and external surfaces, therefore enlarging the radiating area of the aluminum radiator and reducing the space volume of the radiator.
Description
Technical field
The utility model relates to a kind of radiator that is used for power transformer, and particularly a kind of material is the radiator that aluminium and profile have special shape integrated radiating fin.
Background technology
At present, the type of cooling of power transformer has: air-cooled, and water-cooled, hydrogen-cooled etc.Wherein, the most widely used type of cooling is air-cooled.Promptly be coolant, in the closed channel of power transformer housing and radiator composition, circulate with the conduction oil.Conduction oil at first absorbs the heat that transformer housing inner part distributes, and the conduction oil inflow radiator after the heat absorption by radiator distribute heat in air, is realized the cooling of conduction oil, and cooled conduction oil is the inflow transformer housing again.
The air-cooled radiator of power transformer mainly contains by the profile branch: 1, steel flat-tube type radiator; 2, steel gilled radiator; 3, steel fin radiator; 4, steel aluminium composite pipe fin radiator.
Steel flat-tube type radiator welds a series of steel flat-tubes on the housing of transformer, radiating surface is the outer surface of steel flat-tube, and the shortcoming that area of dissipation is little, heat conduction efficiency is low, steel consumption is big, corrode is easily arranged.
The monolithic radiator of steel gilled radiator is that two rectangular plate shape edges of plate welding are made, and multi-disc is used in combination.The steel gilled radiator has increased area of dissipation by adopting the chip radiating subassembly, but because of the overall dimension that is subjected to the transformer housing limits, the monolithic overall dimension and the number of combinations of steel gilled radiator are restricted.The steel gilled radiator has just increased area of dissipation, and the shortcoming of other shortcomings, especially corrosion-resistant that does not overcome the steel flat-tube radiator is more outstanding.
The steel fin radiator is to be skeleton with the steel pipe, and steel sheet fin is through on the steel pipe, adopts hydraulic pressure or mechanical expanding technology that steel pipe is closely contacted with fin again.By using fin, the steel fin radiator has increased area of dissipation, and the heat dissipation capacity of the steel fin radiator of same space volume is 1.87 times of steel gilled radiator.But the fin of steel fin radiator is that physics contacts with steel pipe as the conduction oil passage, is not integrative-structure, forms bigger thermal resistance between fin and steel pipe.Simultaneously, the fin that pierces is difficult to guarantee installation dimension; Fin is thinner, easy deformation; The expansion tube process complexity causes mechanical damage easily, causes hidden danger such as leakage of oil.
Steel aluminium composite pipe fin radiator is with the interior pipe of steel pipe as multiple tube, with the outer tube of aluminum pipe as multiple tube, adopts rolling mill practice to roll out fin at outer aluminum pipe.The heat dissipation capacity of steel aluminium composite pipe fin radiator is suitable with the steel fin radiator, but technology is complicated more, and forms electrochemical corrosion easily between the steel aluminium.
Summary of the invention
For overcoming the low and little deficiency of area of dissipation of at present existing various radiator heat efficient, the utility model provides a kind of radiator, this radiator not only satisfies the functional requirement of the cooling heat dissipation of power transformer fully, also has heat efficiency height, area of dissipation is big, spatial volume is little advantage.
The technical scheme that its technical problem that solves the utility model adopts is: 1, with the material of aluminium as the manufacturing radiator, realize the raising of the Aluminium Radiator heat efficiency.Because of the conductive coefficient of aluminium is 238.07kw/m ℃, the conductive coefficient of carbon steel is 58kw/m ℃.The conductive coefficient of aluminium is about 4 times of carbon steel; 2, utilize aluminium to be easy to machining characteristics, adopt ripe mold integral expressing technique, the disposable inside conduction oil passage that processes Aluminium Radiator and perpendicular to the fin of inner passage outer surface improves the area of dissipation of Aluminium Radiator.With specification is that one group of steel gilled radiator of 500 * 500 * 2000 is reference, and in same spatial volume, the external surface area of aluminum fin radiator is 192m
2, the external surface area of steel gilled radiator is 28m
2, the area of dissipation of aluminum fin radiator is about 6.9 times of steel gilled radiator.
In addition, owing to adopted the material of metallic aluminium as radiator, the corrosion resistance of aluminum integral type fin radiator is better than various steel radiators.Because corrosion resistance is strong, in the urban construction field, be 3 times of steel radiator the useful life of Aluminium Radiator; Because the fin of whole machine-shaping has played the effect of ribs perpendicular to outer surface, the bearing capacity of aluminum integral type fin radiator obtains by force; Because area of dissipation is big in the unit volume, under the prerequisite that guarantees heat-sinking capability, the volume of aluminum integral type fin radiator greatly reduces.
The beneficial effects of the utility model are that the heat efficiency of raising radiator has increased the area of dissipation in the radiator unit volume, has prolonged the useful life of radiator.
