Description
Technical field
The utility model belongs to the attachment technique field of transformer, is specifically related to a kind of energy-conservation isothermal radiation sheet of transformer radiator.
Background technology
The reason known as industry, the radiating effect of radiator and efficient depend primarily on the fin that constitutes radiator.Structure such as Fig. 1 of the fin of the transformer radiator in the prior art illustrate, it comprise forward and backward 1,2 opposite each other, accordingly be formed in forward and backward 1, the advancing of 2 upper and lower end central part, oil return opening 3,4, with a cloth form form in the barrier 7 that is used for the cavity volume between forward and backward 1,2 is separated out some groups of thermal dispersion oil cavities 6 on forward and backward 1,2.During work, the deep fat in the oil tank of transformer is introduced from oil-in 3, is distributed to through minute oil pocket 5 and respectively organizes thermal dispersion oil cavity 6, goes into oil tank of transformer 4 times from oil return opening then.The fin of said structure since with oil-in 3 and oil return opening 4 be arranged on forward and backward 1 accordingly, the upper and lower end of 2 central authorities, during therefore at oil-in 3 introducing heat radiation oil and through 5 shuntings of minute oil pocket, what be in the middle part also promptly can at first obtain heat radiation oil because of the advantage of being in a favoured position from oil-in 3, the nearer relatively thermal dispersion oil cavity 6 of oil return opening 4, and can show full state all the time, and the thermal dispersion oil cavity 6 that promptly is away from oil-in 3, oil return opening 4 relatively of far-end tends to show opposite state.Thereby cause following problem, oil in the nearer thermal dispersion oil cavity 6 of oil-in 3, oil return opening 4 can not fully exchange and take a shortcut, directly flow back in the transformer, and the thermal dispersion oil cavity 6 of far-end can not be brought into play due effect, that is: the good heat dissipation effect of Zhong Jian thermal dispersion oil cavity 6, and the radiating effect of the thermal dispersion oil cavity 6 of both sides is poor.Industry claims that this phenomenon is oily short circuit, therefore will certainly influence the radiating efficiency of radiator, prolongs heat exchanger time.Traditional way is to strengthen the surface area of forward and backward fin 1,2, still, often causes the atypical problem of attending to one thing and lose sight of another, as: cause radiator integral bulky, the material of forward and backward fin 1,2 is made in waste.
Chinese patent CN2694447Y has noticed the problems referred to above, is staggered in oil-in, the be provided with position of oil return opening (patent weighs up hydraulic fluid port) on radiator, and two kinds of schemes are specifically arranged, the one, oil-in, oil return opening are arranged on the both sides upper and lower end of radiator; The 2nd, oil-in is located on the side of radiator, oil return opening is located at the middle part of the opposite side of radiator.The applicant thinks that this scheme can improve radiating effect to a certain extent, but, the deep fat of introducing from oil-in can not be simultaneously and all sidedly equilibrium draw and to each (owning) thermal dispersion oil cavity, often the thermal dispersion oil cavity near the oil-in place takes the lead in obtaining, and therefore still is implied with oily short circuit phenomenon to a certain extent.
Chinese patent CN200944338Y recommends to have a kind of transformer overhead type radiator, specifically adopted the scheme of hot and cold oil pocket, but so structure is comparatively complicated, and especially the setting owing to hot and cold oil pocket is tied up a large amount of zones of fin, thereby influences the performance of radiating efficiency, effect.
Summary of the invention
Task of the present utility model is that the deep fat that will provide a kind of energy will come from oil-in balancedly is distributed to and goes in all thermal dispersion oil cavities of fin and use to embody that oily short circuit phenomenon can not take place isothermal and can also be beneficial to and dwindle the energy-conservation isothermal radiation sheet that the fin volume is realized the transformer radiator of energy-conservation, material-saving.
Task of the present utility model is finished like this, a kind of energy-conservation isothermal radiation sheet of transformer radiator, it comprise the identical equal and opposite in direction of a pair of shape and combine Face to face before, rear panel, corresponding before being formed in, on the rear panel, advancing of the central part of lower end, oil return opening, with a cloth form form in before, being used on the length direction of rear panel scoops out by minute oil pocket and introduces the thermal dispersion oil cavity of deep fat and be located at being used between the thermal dispersion oil cavity thermal dispersion oil cavity is carried out the one group of barrier that separates, characteristics are: the upper end on described one group of barrier is stuck in the upper end of thermal dispersion oil cavity, and be stretched in the branch oil pocket, minute oil pocket is separated into the Fen You district that equates with the quantity of thermal dispersion oil cavity, the lower end of one group of barrier is stuck in the lower end of thermal dispersion oil cavity, and be stretched in the remittance oil pocket, the remittance oil pocket be separated into the remittance oil district that equates with the quantity of thermal dispersion oil cavity.
In an embodiment of the present utility model, barrier in centre in described one group of barrier be with advance, oil return opening is corresponding, and its upper and lower end all with vertical state be stuck in thermal dispersion oil cavity, and the upper and lower end of all barriers of the barrier both sides that mediate all with bending state be stuck in thermal dispersion oil cavity.
In another embodiment of the present utility model, the overbending direction of described bending is that a barrier towards the centre bends.
Go back among the embodiment of the present utility model, the shape in described Fen You district is fan-shaped.
In another embodiment of the present utility model, described shape of converging the oil district is fan-shaped.
In another embodiment of the present utility model, described thermal dispersion oil cavity is fitted to each other and constitutes by forming on forward and backward forward and backward heat radiation tongue respectively.
In of the present utility model and then embodiment, the shape of cross section of described forward and backward heat radiation tongue is a watt shape.
The advantage of the technical scheme that the utility model is recommended: be stretched over branch respectively owing to will be used to separate the two ends of one group of barrier of each thermal dispersion oil cavity, in the remittance oil pocket, dividing, the zone of remittance oil pocket is separated out branch respectively, the oil that converges is distinguished, thereby can make the heat radiation oil in the branch oil pocket in time be assigned in each thermal dispersion oil cavity equably, and then by each remittance oil district remittance remittance simultaneously oil pocket, therefore can avoid the generation of oily short circuit phenomenon, improve the integral heat sink effect of fin, and then the radiating efficiency that makes radiator obtains ultimate attainment improvement, and can with before, the volume-diminished of back fin embodies energy-conservation and economical with materials.
