Description

A kind of radiator for transformer with fin
Technical field
The utility model is related to heat sink technology field, specifically a kind of radiator for transformer with fin.
Background technology
Household electricity is closely related with our daily life, and electric power needs the conversion of transformer, and the fortune of transformer It is also harsh comparing as environment, substantial amounts of heat can be produced due to transformer in the course of the work, has a strong impact on transformer Performance, in transformer station high-voltage side bus, the loss in winding and iron core can produce amount of heat, it is necessary to dissipate away in order to avoid overheating in time And cause insulation damages.At present, oil-filled transformer is to reach to reduce the temperature rise of immersion oil in transformer, piece using its radiator Formula radiator is into each fin is that two panels group is welded into one after being pressed into flute profile oil duct by sheet metal by multiple groups of fins Piece fin, then group is welded into gilled radiator again.Effective area of dissipation of existing radiator fin is small, is vulnerable to around transformer Space limits, and radiating is not uniform enough, and fin utilization rate is low, and efficiency effect is poor.
Therefore, design that a radiating is uniform to overcome the shortcomings of above-mentioned technology, fin utilization rate can be improved, radiating A kind of good radiator for transformer with fin of effect, exactly inventor's problem to be solved.
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 fin Device, its radiating is uniform, can improve fin utilization rate, and good heat dissipation effect reduces transformer overheat and causes to damage, and reduces product Cost.
The utility model solves the technical scheme that its technical problem used:A kind of transformer radiating with fin Device, it includes oil collecting pipe, lower oil collecting pipe, fin, adpting flange, fin, the end of the upper oil collecting pipe and lower oil collecting pipe Be provided with adpting flange, be communicated with several heat sink plates between the upper oil collecting pipe and lower oil collecting pipe, the fin be by After sheet metal has been pressed into flute profile oil duct, two panels sheet metal group is welded into a piece of fin, and the section of the fin is tied for oval Structure, and the connection of every three fin constitutes one group of groups of fins, and multiple groups of fins are provided with the heat sink plate, it is described to dissipate The circular arc both sides in backing section are provided with fin, and the fin of adjacent two heat sink plate mutually staggers setting.
Further, the distance between described adjacent two groups of fins is one group of half of groups of fins lateral length.
Further, the material of the fin is stainless steel.
The beneficial effects of the utility model are:
1st, the utility model passes through to increase fin on a heat sink, in the oil duct during cooling oil flows through fin, fin Equivalent to the contact area that increased fin and outside air, that is, heat exchange is enhanced, therefore the radiating of fin can be improved Fin between efficiency, and different heat sink plate mutually staggers settings, is conducive to air circulation, improves fin and utilizes Rate, good heat dissipation effect, it is possible to decrease product cost.The material of fin is stainless steel, is difficult to get rusty, and heat-transfer effect is good, is beneficial to Radiating.
Brief description of the drawings
Fig. 1 is the utility model structured heat sink front view.
Fig. 2 is the utility model fin cross section structure schematic diagram.
Description of reference numerals:1- adpting flanges;2- fin;The upper oil collecting pipes of 3-;Oil collecting pipe under 4-;5- fins;6- radiates Sheet.
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 structured heat sink front view referring to Fig. 1, is the utility model fin cross section structure referring to Fig. 2 Schematic diagram, a kind of radiator for transformer with fin of the structure, including upper oil collecting pipe 3, lower oil collecting pipe 4, fin 2, company Acting flange 1, fin 5, upper oil collecting pipe 3 are provided with adpting flange 1, upper oil collecting pipe 3 and lower oil collecting pipe with the end of lower oil collecting pipe 4 Several heat sink plates 6 are communicated between 4, fin 2 is that after being pressed into flute profile oil duct by sheet metal, two panels sheet metal group is welded into one Piece fin, the section of fin 2 is ellipsoidal structure, and the connection of every three fin 2 constitutes one group of groups of fins, fin Multiple groups of fins are provided with plate 6, the circular arc both sides in the section of fin 2 are provided with fin 5, adjacent two heat sink plate 6 Fin 5 mutually staggers setting, in adjacent two heat sink plate 6, the correspondence of fin 5 on one of heat sink plate 6 another dissipate The distance between the position of the connectivity part of fin 2 on backing plate 6, adjacent two groups of fins are one group of groups of fins lateral length Half.
The utility model on fin 2 by increasing fin 5, in the oil duct during cooling oil flows through fin 2, fin 5 equivalent to the contact area that increased fin 2 and outside air, that is, enhance heat exchange, therefore can improve dissipating for fin 2 Fin 5 between the thermal efficiency, and different heat sink plate 6 mutually staggers setting, is conducive to air circulation, improves fin 2 Utilization rate, good heat dissipation effect, it is possible to decrease product cost.The material of fin 5 is stainless steel, is difficult to get rusty, and heat-transfer effect is good, Beneficial to radiating.
