Description
Technical field
The utility model is related to transformer radiator technical field, and specifically a kind of transformer with deflector is used
Radiator.
Background technology
With developing rapidly for social economy, the power industry of China is also going from strength to strength.During transformer is power industry
Essential power equipment.Oil-filled transformer is the wide a kind of transformer used in various transformers.And transformation
The environment of operation of device is also harsh comparing, can produce substantial amounts of heat due to transformer in the course of the work, has a strong impact on change
The performance of depressor, the now cooling of transformer mainly uses gilled radiator.If stream speed oil is relatively low in fin oil duct, can shadow
Its radiating efficiency is rung, the utilization rate of fin is reduced, efficiency effect is poor.Piece fan near wall oil flow rate degree it is very low, mainly because
For the presence of flow boundary layer causes that near wall oil stream receives viscous force and acts on, low speeds flow region is belonged in piece group shoulder, this
Sample not only wastes the initial velocity into inside piece group, also affects the heat transfer effect of gilled radiator.
Therefore, a simple structure, increase stream oil flow rate, raising fin are designed to overcome the shortcomings of above-mentioned technology
A kind of radiator for transformer with deflector of utilization rate and radiator heat-dissipation effect, exactly inventor is to be solved asks
Topic.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of transformer radiating with deflector
Device, its simple structure increases stream oil flow rate, improves fin utilization rate and radiator heat-dissipation effect.
The utility model solves the technical scheme that its technical problem used：A kind of transformer with deflector is used and dissipated
Hot device, it includes oil collecting pipe, lower oil collecting pipe, fin, and the upper oil collecting pipe is provided with the end of lower oil collecting pipe and is connected
Flange, is connected between the upper oil collecting pipe and lower oil collecting pipe by fin, the piece group shoulder of the fin by upper oil collecting pipe,
The center of lower oil collecting pipe inclines to both sides, is respectively arranged with deflector in the two ends oil duct of the fin, the fin with
The deflector upper angled degree of upper oil collecting pipe connectivity part is less than the gradient of lower part, the fin and lower oil collecting pipe connectivity part
Deflector upper angled degree more than lower part gradient.
Further, the fin line angulation of the upper oil collecting pipe, the center of lower oil collecting pipe and outermost side with
Horizontal sextant angle is 4 °~8 °.
The beneficial effects of the utility model are：
1st, the upper and lower ends of each fin of the utility model are provided with deflector, and radiating oil passes through fin upper end water conservancy diversion
During plate, because upper opening is than shallower, therefore during by deflector, flow velocity increases.The water conservancy diversion that radiating oil passes through fin lower end
During plate, because the upper angled degree of deflector is larger, therefore during by deflector, flow velocity is become again gently again, and such flow velocity is being handed over
During replacing, the overall radiating effect of fin can be increased.
2nd, the utility model fin piece shoulder and horizontal sextant angle are 4 °~8 °, can avoid what stream oil was caused in low speeds flow area
Speed slows down, and can improve the heat transfer effect of gilled radiator.
Brief description of the drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure left view.
Description of reference numerals：1- adpting flanges；2- fin；The upper oil collecting pipes of 3-；Oil collecting pipe under 4-；5- deflectors.
Specific embodiment
With reference to specific embodiment, the utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values also fall within application
Appended claims limited range.
It is the utility model structural front view referring to Fig. 1, is the utility model structure left view, the structure one referring to Fig. 2
Plant the radiator for transformer with deflector, including upper oil collecting pipe 3, lower oil collecting pipe 4, fin 2, upper oil collecting pipe 3 and next part
The end of oil pipe 4 is provided with adpting flange 1, is connected by fin 2 between upper oil collecting pipe 3 and lower oil collecting pipe 4, upper oil collecting pipe
3rd, the line angulation of fin 2 and horizontal sextant angle of the center of lower oil collecting pipe 4 and outermost side are 4 °~8 °, fin 2
Two ends oil duct in be respectively arranged with deflector 5, fin 2 is less than with the upper angled degree of deflector 5 of the connectivity part of upper oil collecting pipe 3
The gradient of lower part, fin is more than the gradient of lower part with the upper angled degree of deflector 5 of the lower connectivity part of oil collecting pipe 4.
The upper and lower ends of each fin 2 are provided with deflector 5, when radiating oil is by 2 upper end deflector 5 of fin,
Because upper opening is than shallower, therefore during by deflector 5, flow velocity increases.The deflector 5 that radiating oil passes through the lower end of fin 2
When, because the upper angled degree of deflector 5 is larger, therefore during by deflector 5, flow velocity is become again gently again, and such flow velocity is being handed over
During replacing, the overall radiating effect of fin can be increased.Fin piece shoulder is 4 °~8 ° with horizontal sextant angle, can avoid stream oil
The speed caused in low speeds flow area slows down, and can improve the heat transfer effect of gilled radiator.
