Description

A kind of charger transformer with heat sink
Technical field
The utility model is related to a kind of transformer, more particularly to a kind of charger transformer with heat sink.
Background technology
Electronic transformer, with the alternating voltage of civil power is changed into after direct current by semiconductor switch device and electricity Subcomponent and high frequency transformer winding constitute a kind of electronic installation of high-frequency ac voltage output, are also the institute in theory of electronics A kind of friendship orthogonal inverter circuit told about.In simple terms, it is mainly by high frequency transformer magnetic core(Iron core)With two or two Coil composition above, they do not change position mutually, from one or more electrical circuit, by alternating electromotive force by electricity Magnetic induction is acted on, and is transformed into alternating voltage and electric current.And in the output end of high frequency transformer, the electricity consumption to one or more Loop, supplies the high-frequency ac or direct current of different voltage class.Charger transformer of the prior art is due to structure design It is unreasonable, cause manufacturing process high, radiating effect is poor, winding A.C.power loss is high;And miniature transformer due to work when environment do not have There is air flow device band to walk heat, it is therefore desirable to preferably radiating.
Utility model content
The utility model purpose is exactly that there is provided a kind of good heat dissipation effect, small volume in order to make up the defect of prior art The charger transformer with heat sink.
The utility model is achieved through the following technical solutions:
A kind of charger transformer with heat sink:With coil holder, coil is wound with coil holder, coil is wrapped with glue Stitch is provided with below band, the coil holder left and right sides, coil, which is connected to outside stitch, coil, is provided with a pair of " E " shaped magnetic cores, " E " word The junction of type magnetic core is provided with black glue, and " E " shaped magnetic core periphery is enclosed with outer adhesive tape;Set above frame on the outside of " E " shaped magnetic core There is metal riser, metal riser upper end is provided with heat sink, and heat sink is contacted with coil top.
Among the middle transverse rod insertion coil of described " E " shaped magnetic core.
The utility model has the advantages that:The utility model is simple in construction, reasonable in design, and manufacture difficulty is low, good heat dissipation effect, And reduce winding A.C.power loss.
Brief description of the drawings
Fig. 1 is the utility model top view.
Fig. 2 is the utility model front view.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in further detail by embodiment:
A kind of charger transformer with heat sink:With coil holder 1, coil is wound with coil holder 1, coil is wrapped with glue Stitch 4 is provided with below band 2, the left and right sides of coil holder 1, coil, which is connected to outside stitch 4, coil, is provided with a pair of " E " shaped magnetic cores 4, The junction of " E " shaped magnetic core is provided with black glue 5, and " E " shaped magnetic core periphery is enclosed with outer adhesive tape 6;" E " shaped magnetic core above skeleton Outside is provided with metal riser 7, and the upper end of metal riser 7 is provided with heat sink 8, and heat sink 8 is contacted with coil top;" E " font Among the middle transverse rod insertion coil of magnetic core
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, the utility model can also have Other implementations.It should be noted that on the premise of conceiving without departing from the utility model, it is any conspicuously improved It all should be fallen within protection domain of the present utility model with modification.

Claims (2)

1. a kind of charger transformer with heat sink, it is characterised in that:With coil holder, it is wound with coil holder outside coil, coil It is enclosed with below adhesive tape, the coil holder left and right sides and is provided with stitch, coil, which is connected to outside stitch, coil, is provided with a pair of " E " font magnetic Core, the junction of " E " shaped magnetic core is provided with black glue, and " E " shaped magnetic core periphery is enclosed with outer adhesive tape;Set on the outside of " E " shaped magnetic core Metal riser is equipped with, metal riser upper end is provided with heat sink, and heat sink is contacted with coil top.
2. the charger transformer according to claim 1 with heat sink, it is characterised in that:Described " E " font magnetic Among the middle transverse rod insertion coil of core.
