Abstract

The utility model relates to a current-sharing-type heat radiator for a transformer. The current-sharing-type heat radiator comprises an upper oil collecting pipe, a lower oil collecting pipe, cooling fins and an oil tank, wherein an oil inlet is formed in one end of the upper oil collecting pipe and is connected with the lower oil collecting pipe by virtue of the cooling fins; an oil hole is formed in the bottom of one end of the lower oil collecting pipe; the oil tank is welded below the oil collecting pipe and is communicated with the lower oil collecting pipe by virtue of the oil hole; an oil outlet is formed in one end of the oil tank. The current-sharing-type heat radiator for the transformer, which is provided by the utility model, has a simple structure, and in each cooling fin, the distance of the transformer oil flowing from the oil inlet to the oil outlet is completely equal, so that each cooling fin has the same heat radiation effect; under the condition of the same number of groups and the same number of fins, compared with the traditional heat radiator, the current-sharing-type heat radiator has better heat radiation effect; under the condition of same heat radiation effect, the number of the fins of the current-sharing-type heat radiator is less than that of the fins of the traditional heat radiator.

Description

A kind of transformer uniform flow type radiator

Technical field

The utility model relates to a kind of composition structure of transformer, is specifically related to a kind of transformer uniform flow type radiator, belongs to transformer technology field.

Background technology

In the winding of transformer, exist resistance, just lossy when having electric current to pass through, these losses show with hot form.Allowing these heats be dispersed into rapidly in air goes just can make transformer to keep for a long time normal operating state.Due to environmental protection and low noise requirement, a lot of high-power transformers are all inclined to oil-immersed self-cooled, cause the sheet number of single group radiator to be on the increase.

Traditional gilled radiator is as 1 of Figure of description, and its oil-in 1 ' and oil-out 2 ' are all in the same side of radiator.Difference due to distance, when transformer oil is mobile in radiator, in each fin 3 ', the flow velocity of oil is not identical, away from the flow velocity in the fin 3 ' of oil-in 1 ' or oil-out 2 ' well below the flow velocity in the fin 3 ' near oil-in 1 ' or oil-out 2 '.And the sheet number of the fin of large capacity self-cooled transformer is a lot, based on above reason, when the sheet number of every group of radiator reaches some, if increase again sheet number, radiating effect role is not quite even worked.

Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved transformer uniform flow type radiator that has, to overcome described defect of the prior art.

Utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of transformer uniform flow type radiator simple in structure, good heat dissipation effect.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of transformer uniform flow type radiator, and it comprises oil collecting pipe, lower oil collecting pipe, fin and oil groove; Wherein, one end of described upper oil collecting pipe is provided with an oil-in, and it is connected by fin with lower oil collecting pipe; Bottom, one end in described lower oil collecting pipe offers an oilhole; Described oil groove is welded in the below of lower oil collecting pipe, and itself and lower oil collecting pipe are communicated with by described oilhole; In one end of described oil groove, be provided with an oil-out.

Transformer of the present utility model is further set to uniform flow type radiator: described oil-in and oilhole are diagonal angle setting, and both diameters are identical.

Compared with prior art, the utlity model has following beneficial effect: transformer of the present utility model is simple with uniform flow type heat spreader structures, it makes transformer oil distance between from oil-in to oil-out in each fin identical, makes every a slice fin all have identical radiating effect; The in the situation that, sheet number identical at group number being identical, this uniform flow type radiator is than traditional radiator heat-dissipation better effects if; In the situation that radiating effect is identical, this uniform flow type radiator can reduce than the sheet number of traditional radiator.

Embodiment

Refer to shown in Figure of description 2 and accompanying drawing 3, the utility model is a kind of transformer uniform flow type radiator, and it is comprised of several parts such as upper oil collecting pipe 1, lower oil collecting pipe 2, fin 3 and oil grooves 4.

Wherein, one end of described upper oil collecting pipe 1 is provided with an oil-in 5, and it is connected by fin 3 with lower oil collecting pipe 2.

Bottom, one end in described lower oil collecting pipe 2 offers an oilhole 6.Described oil-in 5 and oilhole 6 are diagonal angle setting, and both diameters are identical.

Described oil groove 4 is welded in the below of lower oil collecting pipe 2, and itself and lower oil collecting pipe 2 are communicated with by described oilhole 6.In one end of described oil groove 4, be provided with an oil-out 7.

Transformer of the present utility model by described oil groove 4 is set, makes transformer oil identical to the distance oil-out 7 from oil-in 5 in each fin 3 with uniform flow type radiator, makes every a slice fin 3 all have identical radiating effect.

Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection range of this creation within all spirit in this creation and principle.
