Specific embodiment
The embodiments of the present invention are further described with reference to the accompanying drawing.
As shown in Figs. 1-2, the present embodiment is related to a kind of heat-dissipating voltage transformer, including iron core 1, winding 2 and setting iron core 1 with
Transformer framework 3 between winding 2.Winding 2 is equipped at intervals with several groups radiating copper band group 4, every group of radiating copper band along direction of winding
One end of group 4 moves into the upper end of winding 2, and the other end moves into the lower end of winding 2.A part edge of every group of radiating copper band group 4
In winding 2, rest part is arranged at 2 outside of winding.In such manner, it is possible to effectively by transformer winding 2 heat and
When the periphery that winding 2 is diffused by radiating copper band group 4, in time radiate.Multiple radiating copper band groups 4 can be arranged at equal intervals
On winding 2, package form is formed in this way.
, the radiating copper band group being arranged with 2 marginal position of winding
It is first group, second group, the multiple groups radiating copper band group 4 such as third group is set on winding 2 far from 2 marginal position of winding, every group dissipates
In the radiating copper band group 2 of previous group is wrapped in by hot copper strips group 4, and do not contacted with the radiating copper band group 4 of previous group.
Wherein, winding 2 includes several terminals, and terminals are arranged on winding 2.2 one end of winding connects an output end
5, terminals can be set in the other end of winding 2, also can be set with 5 the same side of output end.The change of the present embodiment design
Depressor is contravariant transformer, and the line of terminals should be thick as far as possible, and wire length is because short as far as possible.
In the present embodiment, every group of radiating copper band group 4 includes upper copper sheet 41 and lower copper sheet 42, and one end of upper copper sheet 41 moves into
In the upper end of winding 2, the other end of lower copper sheet 42 is moved into the lower end of winding 2.In this way, straight by upper copper sheet 41 and lower copper sheet 42
It connects and moves into winding 2, more preferably directly the heat in winding 2 can radiate by upper copper sheet 41 and lower copper sheet 42.
Meanwhile in the present embodiment, opening, upper copper sheet 41 and the lower copper sheet opposite with the opening of lower copper sheet 42 of upper copper sheet 41
42 shape is U-shaped or Jiong type.In this way design, radiating copper band group 4 can it is as much as possible absorb winding 2 on heat, winding 2
Heat inside upper and lower ends can be transferred out by radiating copper sheet group 4 come；It is oppositely arranged, can either be reduced by the two opening
Its space, additionally it is possible to absorb the heat of 2 outside of winding；It is shaped to U-shaped or Jiong type, is for that heat dissipation can be increased
Area, and for reducing whole volume.Certainly, the application is not limited to its shape, may be designed as other forms
Appearance, such as to hook type.
In the actual production process, it is spaced setting between upper copper sheet 41 and lower copper sheet 42, makes both outside winding 2
Part is not connected to.It designs in this way, it, still can be more convenient when carrying out coiling to winding 2.If upper copper sheet 41 and lower copper
Piece 42 links together, and is thus unfavorable for winding 2 and carries out coiling.
As a preference, the present embodiment winding 2 is equipped with one group of radiating copper band group 4 in 5 side of output end, the other side is equipped with
Three groups of radiating copper band groups 4.It is more conducive to radiate in this way, multiple radiating copper band groups 4 are arranged, because winding 2 is provided with output end at one end
5, space is limited, so 4 negligible amounts of radiating copper band group of setting；The input of the other side is carried out by conducting wire, empty
Between it is larger, so the more multiple radiating copper sheet group 4 of setting.
In order to improve the safety of the application transformer, it is all provided between winding 2 and radiating copper band group 4, winding 2 and iron core 1
