Brief description of the drawings
Fig. 1 is the schematic perspective view of the embodiment of transformer one of the present utility model;
Fig. 2 is the top view of transformer in Fig. 1;
Fig. 3 is the side view of transformer in Fig. 1.
Embodiment
The utility model is described in detail shown each embodiment below in conjunction with the accompanying drawings, but it should explanation, These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works Energy, method or equivalent transformation or replacement in structure, are belonged within the scope of protection of the utility model.
As shown in Figures 1 to 3, transformer of the present utility model includes:High-pressure side winding 10, low-pressure side winding 20 and radiating Device 30.
The high-pressure side winding 10 is set on the magnetic core of the transformer, and it is used for the electric energy for receiving external power source.Its In, the high-pressure side winding 10 is formed by enamel-covered wire coiling, and enamel-covered wire referred to herein refers to traditional cross section for circular copper Line.In order to realize the electric energy for receiving external power source, the both ends that coiling forms the enamel-covered wire of the high-pressure side winding 10 are formed respectively The the first connection end C and second connection end D of the high-pressure side winding 10, so as to be connected by the first connection end C and second End D can be electrically connected with external power source, and realize the purpose for the electric energy for receiving external power source.
The low-pressure side winding 20 is set on the magnetic core of the transformer, its electric energy being used for after supply load decompression. Wherein, in order to which the temperature rise of the high-pressure side winding 10 is exported, and bear it is larger by electric current, the low-pressure side winding 20 by The coiling of copper strips 21 forms, and the copper strips 21 conducts with the high-pressure side winding heat.Copper strips 21 referred to herein refers to be shaped as partially Copper coin flat-shaped and in uniform thickness, its relatively conventional enamel-covered wire, winding is smooth, neat, and transformer window area is available Rate is higher, and the cross sections product of uniform window copper strips 21 is bigger than the cross sections product of circular copper cash, can pass through bigger electric current.
In addition, in order to realize the electric energy after supply load decompression, coiling forms the copper strips 21 of the low-pressure side winding 20 Both ends form the 3rd connection end A and the 4th connection end B of the low-pressure side winding 20 respectively, so as to pass through the 3rd connection end A and the 4th connection end B can be electrically connected with load, and realize the purpose of supply load electric energy.
The radiator 30 is connected with the low-pressure side winding 20, its be used to receiving the low-pressure side winding 20 transmit and The heat come, and realize the Homogeneouslly-radiating of heat.As a kind of embodiment, the heat-sink unit of radiator 30 first and second Radiator unit, both ends of the above-mentioned heat-sink unit respectively with the copper strips 21 are connected, and the radiator 30 and the copper strips Link position between 21 is close to the 3rd connection end A and the 4th connection end B.Preferably, the radiator 30 and the copper It is connected between band 21 by fixed screw 40.
Further, the radiator 30 has shell and houses what be installed in the shell some be arranged in parallel Radiating fin, wherein, the copper strips 21 is connected with the shell, so as to which the high-pressure side winding 10 can conduct heat to On the copper strips 21 of the low-pressure side winding 20, the copper strips 21 further conducts heat to coupled radiator shell On, the shell is realized eventually through radiating fin therein to radiate.
Therefore, because the size that the size for the electric current that transformer output winding can pass through both had been accumulated with winding copper material cross sections Relevant, also relevant with the temperature of use environment, i.e. the lower electric current that can pass through of temperature is also bigger.So as to due to copper strips 21 Cross sections product is bigger than the cross sections product of circular copper cash, while radiator 30 can take away the temperature of high-pressure side winding 10, so originally The transformer of utility model can be by bigger electric current compared to existing transformer, while efficiently solves the temperature rise of transformer Problem.
In summary, transformer radiating stabilization of the present utility model, perfect heat-dissipating and radiating efficiency are high, and it is effectively solved The problem of temperature rise of transformer, and can pass through bigger electric current compared to existing transformer.
