A kind of high frequency transformer of high efficiency and heat radiationTechnical field
Technical field of transformer manufacturing is the utility model is related to, specially a kind of high frequency transformer of high efficiency and heat radiation.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondaryLevel coil and iron core, actual transformer composition structure is sufficiently complex, is inevitably present copper loss and iron loss, i.e. coil resistanceHeating and fever phenomenon unshakable in one's determination, and the high frequency transformer under hot operation state can not only damage internal component, itselfService life can also be reduced, and transformer device at this stage is divided by the type of cooling, there is dry-type transformer device and oil-filled transformer,Dry-type transformer carries out natural cooling or increase blower fan cooling by cross-ventilation, is used for skyscraper, high speed toll stationThe small capacity transformer such as electricity consumption and local lighting, electronic circuit, and oil-filled transformer by oil make cooling medium, such as oil immersion fromCold, oil, oil immersed water cool, forced oil-circulation etc., and existing oily circularly cooling has that oil consumption is big, radiating effect difference lacksPoint, the heat that oil circulation is taken out of can not effectively disperse.
Utility model content
In order to overcome the shortcomings of prior art, the utility model provides a kind of high frequency transformer of high efficiency and heat radiation, energyIt is enough to realize efficient oil circulation and the carrying of temperature, while realize quick oil temperature radiating.
Technical scheme is used by the utility model solves its technical problem：A kind of high frequency transformer of high efficiency and heat radiation,Including body, silicon steel sheet and around copper, it is characterised in that：The outer surface surrounding of the body is evenly arranged with fin, and eachFin described in piece is internally provided with the hair clip bend pipe of stack-type, and the hair clip bend pipe is connected with pump group, the pump group by pipelineOil body pump in pipeline to body left end is set in hair clip bend pipe, then the radiating of the copper loss by being wound around copper both side surface adaptabilityPipe connection circulation, each copper loss radiating tube connects the hair clip bend pipe in a piece of fin, and the copper loss radiating tube passes throughTaper pipe and be connected with hair clip bend pipe, be provided with blower fan group at the top of the fin, and the blower fan group is uniformly arranged on bodyThe outer surface at top, the silicon steel sheet outer wall are set with bidirectional cooling pipe, and the oil inlet and oil-out of the bidirectional cooling pipeIt is separately positioned on silicon steel sheet left upper end and bottom righthand side.
As a kind of preferable technical scheme of the utility model, the pipe both ends bore of tapering is different, into round table-like.
As a kind of preferable technical scheme of the utility model, the blower fan group is made up of some electric fans, and and finTop is tightly connected.
As a kind of preferable technical scheme of the utility model, the bidirectional cooling ligament is sleeved on the table of silicon steel sheetFace, and oil inlet and oil-out are connected with pump group.
As a kind of preferable technical scheme of the utility model, the section of the bidirectional cooling pipe overarches the shape of door,The section of the copper loss radiating tube is " D fonts ".
As a kind of preferable technical scheme of the utility model, the bidirectional cooling pipe equally connects organism front and rear sidesThe hair clip bend pipe structure in fin that face is set.
Compared with prior art, the beneficial effects of the utility model are：By in fin set hair clip bend pipe andBlower fan group is set at the top of fin, the copper loss radiating tube circulated by pump group and the heat carried in bidirectional cooling pipe transmitHeat is quickly dispersed to fin, and by the downward air blast of blower fan group, while the stack-type hair clip bend pipe set, realize oilRoad is circulated in extra-organismal long path, so as to abundant and quickly take away heat, improves the efficiency of its radiating.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried outClearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than wholeEmbodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is madeThe every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment：
As shown in figure 1, the utility model provides a kind of technical solution, including body 1, silicon steel sheet 2 and around copper 3, itsIt is characterised by：The outer surface surrounding of the body 1 is evenly arranged with fin 4, and is internally provided with per a piece of fin 4The hair clip bend pipe 8 of stack-type, the hair clip bend pipe 8 are connected with pump group 10 by pipeline, and the pump group 10 is by the oil body pump in pipelineSet to the left end of body 1 in hair clip bend pipe 8, then the copper loss radiating tube 6 by being wound around the both side surface adaptability of copper 3 connects circulation,Each copper loss radiating tube 6 connects the hair clip bend pipe 8 in a piece of fin 4, and the copper loss radiating tube 6 is by tapering pipe 7Hair clip bend pipe 8 is connected with, the top of fin 4 is provided with blower fan group 5, and the blower fan group 5 is uniformly arranged on body 1 and pushed upThe outer surface in portion, the outer wall of silicon steel sheet 2 are set with bidirectional cooling pipe 9, and the oil inlet and oil-out of the bidirectional cooling pipe 9It is separately positioned on the left upper end of silicon steel sheet 2 and bottom righthand side.
As shown in Figures 2 and 3, the gap of bidirectional cooling pipe 9 is sleeved on the surface of silicon steel sheet, and oil inlet and oil-outBe connected with pump group 10, oil body be passed through by the oil inlet of bidirectional cooling pipe 9, after by the both sides of silicon steel sheet 2 circulate, finally collect inOil-out, so as to take away the heat of silicon steel sheet surrounding, while it can be good at by the bidirectional cooling pipe 9 in gate section and silicon steelPiece surface is bonded, and makes the carrying of temperature highly efficient.
As shown in figure 3, the straightway of the copper loss radiating tube 6 in " D " the type section provides radiating tube in irregularly around copper（3）The good contact area on surface, the surface further around copper 3 is wound by adaptability, can effectively absorb the heat of copper loss.
Preferably, the both ends bore of pipe 7 that tapers is different, into round table-like；The blower fan group 5 is made up of some electric fans,And it is tightly connected with the top of fin 4；The section of the bidirectional cooling pipe 9 overarches the shape of door, the copper loss radiating tube 6Section is " D fonts "；The hair clip that the bidirectional cooling pipe 9 is equally connected in the fin 4 of the front and rear sides face of organism 1 setting is curvedThe structure of pipe 8.
