The winding structure schematic diagram of multiple transformator monomer coils that Fig. 3 provides for this utility model embodiment.
Wherein, in order to improve this utility model embodiment provide high-frequency water-cooling transformator in transformator monomer 4 coil between coupling, as it is shown on figure 3, the primary coil 42 of each transformator monomer 4 and secondary coil 43 all adopt the mode of continuous coiling tightly around being formed on iron core 41.Adopt the mode of closely coiling continuously, it is ensured that gapless between coil, coupling is good, it is achieved that the performance of the less leakage inductance of transformator.
It should be added that, the iron core 41 of each transformator monomer 4 can adopt " E " shape or canned Ferrite Material.Preferably, iron core 41 can adopt can-shaped ferrite core.
Specifically, in order to realize between primary coil 42 and the secondary coil 43 of each transformator monomer 4 concordance, coupling preferably, as it is shown on figure 3, the independent coiling of secondary coil 43, primary coil 42 closely press from both sides successively around secondary coil 43 around.When being embodied as, first by independent for secondary coil 43 coiling and carry out insulation processing, then by each primary coil 42 first around one layer, then pack into secondary coil 43 respectively, primary coil 42 is continued around secondary coil 43 successively continuously folder around completing.Such winding method is possible not only to ensure that coil winding ground uniformity, coupling are good, and is simultaneously achieved the less leakage inductance performance of transformator.
Preferably, in order to make primary coil 42 and secondary coil 43 have good electric conductivity and heat conductivity, as shown in Figure 3, the wire of primary coil 42 can adopt litz wire, the wire of secondary coil 43 can adopt copper tube, and wherein copper tube can conduct electricity, can water flowing in copper tube pipeline, water-electricity integrated, not only can realize the electric conductivity of copper tube but also can have water cooling effect；Simultaneously, in order to realize good insulation effect, two layers of film-insulated isolation of imines of the half lap held on the turn-to-turn wire of primary coil 42, the turn-to-turn insulating paper strip of secondary coil 43 holds isolation, the imines thin film held on wire and insulating paper strip isolation it is used that between coil interlayer, coil, it is achieved thereby that preferably insulation effect.
It should be added that, litz wire sectional area is 3-9mm by size of current by single sectional area2Many litz wires compose in parallel；Copper tube thickness can be 1.5mm or 2mm, internal diameter can be 8mm-40mm not etc., transformer coil can be circular or rectangular configuration；Half lap two layers is by making later layer insulation film push down 1/2 realization of preceding layer insulation film overall width.During actual manufacture, the wire of the primary coil 42 of transformator can adopt sectional area to be 36mm2Imines thin film bag litz wire, the wire of secondary coil 43 can adopt sectional area to be 59mm2, internal diameter 11mm or internal diameter 14mm T2 copper tube.
During practical application, in order to strengthen the cooling effect to transformer coil (primary coil 42, secondary coil 43) and iron core 41, improve work efficiency, as shown in Figures 2 and 3, secondary coil 43 two ends are respectively connected with cooling water water nozzle 5, this cooling water water nozzle 5 can be connected to water cooling tube 6, and water cooling tube 6 is respectively arranged on the two ends up and down of multiple transformator monomer 4, forms loop.Therefore, fixing by being arranged close to transformator water cooling tube 6 up and down, it is possible to achieve to transformer core 41 and coil (primary coil 42, secondary coil 43) preferably cooling effect, make high-frequency water-cooling transformator realize less intensification.
It should be added that, water cooling tube 6 according to cooling effect, can adopt the water cooling tube of internal diameter 31mm or internal diameter 35mm to be pressed into wide 42mm, thick 12mm, so can so that water cooling tube 6 fixing.

It should be added that, under the premise meeting technological requirement, fairing 3 is the smaller the better with the distance of transformer body 4, for instance, it is possible to it is 25mm.
Specifically, owing to high-frequency water-cooling transformator needs receive electric energy and export larger current, to ensure the temperature rise effect that transformer body is less simultaneously, as depicted in figs. 1 and 2, first copper bar 1 and the second copper bar 2 are connected to lead-in wire (not shown), respective lead is fixed near water cooling tube 6, so that the first copper bar 1 and the second copper bar 2 can double as secondary bus bar and positive bus-bar row respectively, simultaneously because the first copper bar 1 and the second copper bar 2 double as the first cooled plate and the effect of the second cooled plate, so, both ensure that the output of high-power high-current, reach again water-cooled effect.
Preferably, in order to realize the stability connected, secondary coil 43 and the connected mode of the second copper bar 2, the first copper bar 1 with the connected mode gone between with the connected mode gone between, the second copper bar 2 all can be connected for bolt or weld in any one.During practical application, the connected mode of secondary coil 43 and the second copper bar 2 can also adopt the auxiliary equipment of studs or standard to be attached.
Further, output electric current in order to realize high-frequency water-cooling transformator is uniform, leakage inductance is little, as shown in Figure 2, each fairing 3 is all consistent with the distance of each corresponding secondary coil 43, fairing 3 can be made to be evenly arranged, and water cooling tube 6 can mate corresponding fixing with fairing 3, ensure that itself and transformator monomer 4 relative distance are nearest, distance is consistent, there is preferably water-cooled effect, it is achieved thereby that the output rectification effect of the high-frequency water-cooling transformator of this utility model embodiment offer is preferably, leakage inductance is less, heat up less, and reached the effect of multiple transformator monomer 4 parallel output current equalizing.
Further; in order to realize good insulation effect; can being respectively equipped with felt pad (not marking in figure) on described first copper bar 1 and described second copper bar 2, this felt pad can also have the effect of cushion concurrently simultaneously, and high-frequency water-cooling transformator is had good protective effect.
Last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although this utility model being described in detail with reference to foregoing embodiments, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein some or all of technical characteristic is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of this utility model.
