Abstract
The utility model discloses a high power density transformer, this transformer include the magnetic core, still include primary, secondary copper sheet, primary, secondary copper sheet are exoskeletal coiling, primary, secondary copper sheet coiling are inside the magnetic core, secondary copper sheet width is less than or equal to magnetic core home record width, the rectangle is personally submitted to main looking, the upper and lower recess that is provided with of its side, and its middle part is cylindrical plug, and primary, secondary copper sheet interval coiling are on this cylindrical plug. The utility model discloses a transformer of high power density, small volume, in current magnetism material and specification, the maximize utilizes and possesies the volume in magnetic core winding space and the power.
Description
Technical field
The utility model relates to transformer, particularly relates to a kind of high-power density transformer.
Background technology
In prior art, high-power PQ type transformer is all the coiling of secondary use copper sheet, and because primary turns is many, general twisted wire or the silk-covered wire of using makes, in the mode specifying under requirement or use barricade insulation or wrap up with adhesive tape the line bag both sides number of turn; If adopt barricade insulation, very large obstruction is existed to product heat radiation; If adopt adhesive tape parcel mode, processing cost is too high.
Therefore, how to provide the transformer of a kind of high power density, small size, on existing magnetic material and specification, in maximum using magnetic core winding space and power supply, possessive volume is technical issues that need to address.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of high-power density transformer.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of high-power density transformer, this transformer comprises magnetic core, also comprise primary coil, secondary copper sheet, described primary coil, secondary copper sheet are exoskeletal coiling, described primary coil, secondary copper sheet are wound on magnetic core inside, described secondary copper sheet width is less than or equal to magnetic core home record width, described main-vision surface is rectangle, its side setting up and down fluted, be cylindrical plug in the middle part of it, primary coil, secondary copper sheet interval are wound on this cylindrical plug.
Further, described magnetic core is bimag.
Further, the side of described primary coil is coiled into the arc-shaped that top is plane.
Further, the side of described secondary copper sheet is coiled into the arc-shaped that top is plane.
Further, described magnetic core seat is on one piece of fixed head, and this fixed head is fixed on pcb board.
Further, described pcb board upper surface is less than 33mm to the whole height of secondary copper sheet.
Relative to prior art, the beneficial effects of the utility model are: the transformer of high power density of the present utility model, small size, on existing magnetic material and specification, and possessive volume in maximum using magnetic core winding space and power supply.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model transformer.
Fig. 2 is the end view 1 of the utility model transformer.
Fig. 3 is the end view 2 of the utility model transformer.
Mark in accompanying drawing: primary coil 1, magnetic core 2, secondary copper sheet 3, pcb board 4.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Please refer to accompanying drawing 1 ~ 2, a kind of high-power density transformer of the present utility model, this transformer comprises magnetic core 2, also comprise primary coil 1, secondary copper sheet 3, described primary coil 1, secondary copper sheet 3 is exoskeletal coiling, described primary coil 1, secondary copper sheet 3 is wound on magnetic core inside, as shown in Figure 3, described secondary copper sheet 3 width is less than or equal to magnetic core home record width (mark a place in figure 3), described main-vision surface is rectangle, its side setting up and down fluted, it is cylindrical plug in the middle part of it, primary coil 1, secondary copper sheet 3 interval is wound on this cylindrical plug, described magnetic core 2 is bimag, the side of described primary coil 1 is coiled into the arc-shaped that top is plane, the side of described secondary copper sheet 3 is coiled into the arc-shaped that top is plane, described magnetic core 2 is on one piece of fixed head, this fixed head is fixed on pcb board 4, described pcb board 4 upper surface is less than 33mm to the whole height of secondary copper sheet 3.The winding method of primary and secondary coil 1 of the present utility model, secondary copper sheet 3 is all exoskeletal coiling, and secondary copper sheet 3 width, close to magnetic core home record width, makes full use of magnetic core inner space, makes transformer efficiency density reach maximum.When circuit requirement 2 transformers, the length of the utility model transformer on pcb board 4 and widely only have 60*45.5mm, only larger than magnetic core little by little, and this high-power density transformer is special-shaped pin set assembling structure, the height more than pcb board is less than 33mm, is up to 33mm, area of dissipation is large, winding uses secondary copper sheet 3, except insulating requirements adhesive tape and the fixing glue used of necessity, and the material of other heat radiations that have no effect.High-power density transformer provided by the utility model, on existing magnetic material and specification, possessive volume in maximum using magnetic core winding space and power supply.
The foregoing is only preferred implementation of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
