The invention provides a finned radiator for an oil-immersed transformer. The finned radiator comprises m*n radiating fins which are arranged in a matrix, wherein the each two adjacent radiating fins in the transverse direction are connected with each other through a reinforcing rib; each two adjacent radiating fins in the longitudinal direction are connected with each other through an inter-fin outer fin; two ends of each of the m*n radiating fins are communicated with two collecting boxes respectively; each collecting box is provided with a connection flange; m and n are numbers of the radiating fins which are transversely arranged and longitudinally arranged respectively; and m and n are positive integers greater than or equal to 2. According to the radiator provided by the invention, a vacuum brazing technology is adopted, so that the contact area of the radiator and the air is effectively improved; the radiator has the characteristics of small size, high cooling capacity and high radiating efficiency; safe operation of the transformer can be ensured under the same dimension; the overall dimension can be reduced under the same cooling power; and the finned radiator meets various requirements of finned radiator industry standards.
Description
Technical field:
The invention belongs to transformer technology field, be specifically related to a kind of oil-filled transformer gilled radiator, for oil-filled transformer cooling, to reduce the oil temperature liter of inside transformer.
Background technology:
Radiator uses on oil-filled transformer, is used for reducing the temperature rise of transformer oil.
When Large Oil immersion transformer runs, owing to there is resistance and magnetic resistance, iron core, coil and steel construction piece all will produce various loss, distributed by fuel tank and the gilled radiator that is connected with fuel tank by transformer oil in the mode of heat energy, to reduce the pasta temperature rise of transformer, improve the useful life of transformer.As circulation power, (in radiator, oily stream mode is laminar flow to the density contrast that gilled radiator relies on the temperature difference of transformer oil reservoir to cause, flow velocity is lower), the outside free convection of air and the own radiation of relying on dispels the heat (based on heat loss through convection), structure is simple, noiselessness, non-maintaining, be widely used.
Along with Based Intelligent Control and the raising of electric pressure and the increase of transformer capacity, requirement for radiator is also more and more higher, size and the cooling capacity of radiator do larger and larger, therefore, a kind of novel transformer gilled radiator of Study and Development, to improve the purchase cost of radiating efficiency and reduction transformer device, just seem ever more important.
Summary of the invention:
The object of the present invention is to provide a kind of oil-filled transformer gilled radiator.
For achieving the above object, the present invention adopts following technical scheme to be achieved:
A kind of oil-filled transformer gilled radiator, comprise m*n the fin in matrix arrangements, laterally be connected by reinforcement between adjacent two fin, longitudinally be connected by outer wing between sheet between adjacent two fin, the two ends of m*n fin 1 are connected with two afflux boxes respectively, and each afflux box is provided with adpting flange; Wherein, m, n are respectively the quantity of the fin of horizontal and vertical layout, and m, n are the positive integer being more than or equal to 2.
The present invention further improves and is: longitudinally adjacent two adopt soldering processes to link together between outer wing between fin and sheet.
The present invention further improves and is: each fin inside is oil duct, and oil duct inside is provided with wing in some oil ducts.
The present invention further improves and is: in some oil ducts, wing is installed vertically on oil duct inside.
The present invention further improves and is: adopt soldering processes to link together in oil duct between wing and the oil duct of fin.
The present invention further improves and is: between sheet, the shape of outer wing is W type, rectangle or circular arc.
The present invention further improves and is: this gilled radiator comprises four fin.
Relative to prior art, the present invention has following beneficial effect:
The present invention is by changing fin inside and outside portion structure, and the mode increasing radiating fin in the inside and outside portion of fin increases area of dissipation, promotes the heat exchange of oil duct interior oil stream and oil duct wall, reaches the object improving radiating effect.
Further, described radiator adopts heat radiating fin structure, thus the area of dissipation of radiator is increased, fin and inside and outside radiating fin adopt soldering processes, the inside and outside wall of radiator and wing fin close contact is made by soldering, ensure that bonding strength simultaneously, reduce the failure rate of radiator and improve the stability of radiator.
Further, this invention fin and material, profile, gauge etc. more flexible and changeable, radiating fin can need to adopt the profiles such as W type, rectangle, circular arc according to design, material can adopt aluminium or harder aluminium alloy, the thickness of radiating fin and overall dimension also can adjust according to design needs, ensure the best radiating effect of radiator, after hardness improves, radiator can be rinsed by giant or pressure-air, avoid the malformation of radiating fin, ensure stability and the useful life of work.
Further, after adjacent trough soldering is fixing, thus can Temperature Distribution on the adjacent wave shaped radiator of homogenizing, make full use of the area of dissipation of each wave shaped radiator, the scattering losses avoiding heat to concentrate causing, increases the service life.
Further, this radiator oil duct front and side all can ventilate, and add fin and air contact surfaces amasss, and improve the cooling effect of radiator.
