Test transformer, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformation
Device, electronic transformer, reactor, mutual inductor etc.).
The high-frequency switch power transformer of electronics industry is deposited always since switching frequency is high and the presence of kelvin effect
In the accumulation of coil heat, cooling insufficient problem.For guarantee transformer safety reliably work, generally can using fan into
Row forced air is cooling, or transformer is placed in metal shell integrally to radiate.But both methods can only be to change
It is cooled down, and the heat of coil inside can not directly be guided outside depressor.The thermal accumlation of coil inside gets off, and is easy to lead
Mutagens depressor internal temperature increases, and then influences the reliability and safety of transformer working performance.
To solve this problem, the Chinese utility model patent of Patent No. 201420115135.8 proposes a kind of high frequency
The radiator of switching mode power supply transformer, the radiator include transformer framework, FERRITE CORE, coil and heat dissipation metal
Piece.By the way that the thermally conductive end of cooling fin to be located between transformer framework and coil, the heat of coil inside can be conducted to scattered
On backing radiating end, then exports to coil outer and distribute.
However the thermally conductive end of cooling fin is located between transformer and coil, cooling fin can be due to the variation in magnetic field in coil
Vortex phenomenon is generated, and then gives out a large amount of thermal energy, causes coil inside temperature to increase, is unfavorable for the heat dissipation of transformer.Again
Cooling fin is first installed on transformer framework by person, radiator needs, then just can carry out coiling to transformer coil,
The method is not easy to the coiling of transformer coil and the repair and replacement of cooling fin.
Utility model content
One of the purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides one kind and is conducive to transformer and dissipates
Heat and the switching mode power supply transformer radiator for being convenient for cooling fin repair and replacement.
To achieve the above object, the utility model embodiment provides following technical solution:
Transformer radiator structure including transformer framework, the magnetic core being sheathed on transformer framework and is wrapped in change
Coil on depressor skeleton, separably attached on magnetic core to have radiator, radiator includes cooling fin, is set to cooling fin
Spring leaf of the two sides in " L " font and the convex block on spring leaf, cooling fin two sides are equipped with card slot, and the upper side wall of card slot is set
There are several through-holes, spring leaf is equipped with groove, is equipped with the elastic steel sheet with salient point in groove.
Preferably, radiating fin is equipped on cooling fin.
Preferably, radiating fin includes left fin and right fin, is equipped with sliding slot in right fin, left fin can be nested in cunning
Slot simultaneously moves up and down.
Preferably, several jacks are equally spacedly equipped on left fin from top to bottom, are equipped with slot, jack in right fin
And bolt is equipped in slot.
Preferably, cooling fin, radiating fin and convex block are formed by aluminium profile.
Preferably, heat-conducting silicone grease is coated between cooling fin and magnetic core.
Due to the adoption of the above technical scheme, compared with prior art, the utility model has the following beneficial effects:
1, radiator is installed on the outside of coil and magnetic core, cooling fin will not because in coil the variation in magnetic field due to generate whirlpool
Effect is flowed, radiator can effectively radiate to transformer, and transformer performance due to high temperature is avoided to decline.
2, it is clamped on the side wall of magnetic core due to radiator by spring leaf and convex block, so can be in transformer
Just radiator is installed on the outside of magnetic core after the completion of coiling.Radiator is separably attached with magnetic core, is easily installed maintenance,
Improve production efficiency.
3, it is provided with through-hole in the upper side wall of card slot, by the way that the salient point on elastic steel sheet to be stuck among through-hole, can adjusted
Position of the spring leaf in card slot, and then the clamping force between adjusting heat dissipation device and magnetic core are saved, to meet different size change
The demand of depressor.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the partial enlarged view in Fig. 1 at A；
Fig. 3 is the structural schematic diagram of radiating fin in the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description.Obviously, described embodiment is only the utility model a part of the embodiment, and not all embodiments.
Based on the embodiments of the present invention, those of ordinary skill in the art obtain all without making creative work
Other embodiments belong to the protection scope of the utility model.
As shown in Figure 1 and Figure 2, transformer radiator structure, including transformer framework 1, be sheathed on transformer framework 1
Magnetic core 2 and the coil 3 that is wrapped on transformer framework 1, it is separably attached on magnetic core 2 to have radiator 4, heat dissipation dress
Setting 4 includes cooling fin 5, the spring leaf 6 set on 5 two sides of cooling fin in " L " font and the convex block 7 on spring leaf 6, heat dissipation
5 two sides of piece are equipped with card slot 8, and the upper side wall of card slot 8 is equipped with several through-holes 9, and spring leaf 6 is equipped with groove 10, sets in groove 10
