Abstract

A water-cooled transformer of a high-power high frequency switching power supply comprises a magnetic core, a heat dissipation copper sheet and output copper plates. The heat dissipation copper sheet is an anaerobic red copper sheet. A water inlet pipe and a water outlet pipe are arranged at the upper portion of the heat dissipation copper sheet. The heat dissipation copper sheet is connected on the surface of a magnetic core in a pressing mode. A primary copper wire is wound on the heat dissipation copper sheet. The magnetic core is fixed through the two copper plates in an oppositely pressing mode. Secondary copper pipes of the transformer penetrate through the output copper plates and the magnetic core. The water-cooled transformer of the high-power high frequency switching power supply has the function of fast cooling, and resolves the cooling problem of a high-power high frequency switching power supply with an ultracrystalline toroidal magnetic core.

Description

A kind of high-power high-frequency switch power supply water-cooled transformer
Technical field
The utility model relates to a kind of high-power high-frequency switch power supply water-cooled transformer.
Background technology
Development along with power technology, the miniaturization of power-supply system, high frequency and high power are than becoming an eternal research direction and development trend, therefore the higher power transformer of frequency of utilization is to reduce the power-supply system volume, improve the key factor of output power of power supply ratio, when yet frequency raises, transformer is one of the highest device that generates heat in high frequency switch power, is easy to cause transformer or other parts damages of high frequency switch power because temperature is high over its limiting value or magnetic saturation.
The utility model content
Its purpose of the utility model provides a kind of high-power high-frequency switch power supply water-cooled transformer with regard to being to overcome above defective, have quick temperature-reducing function, has solved the cooling problem of high-power high-frequency power transformer of amorphous, ultracrystallite toroidal core.
The technical scheme that the utility model is taked to achieve these goals, comprise magnetic core, radiating copper sheet, the output copper coin, radiating copper sheet is the anaerobic copper sheet, the top of radiating copper sheet is provided with water inlet pipe and outlet pipe, radiating copper sheet is crimped on the magnetic core surface, elementary copper enamelled wire is wound on radiating copper sheet, and magnetic core becomes fixed form by the output copper coin to swaging, and the transformer secondary output copper pipe passes output copper coin and magnetic core.
Compared with prior art, the utility model has the advantage of.
1, adopt the water-cooled copper type of cooling, reduced secondary heating, improved the rectification efficiency of transformer.
2, the cooling water that constantly circulates can be taken away a part of temperature of transformer, allows transformer remain in the safe temperature scope.
3, described radiating copper sheet is the anaerobic copper sheet, and conductive coefficient has improved the transformer radiating efficiency up to 422w/mk.
4, the transformer global shape is annular, and this transformer is less than general voltage device volume, saves space and cost, has facilitated design and has installed, have advantages of that efficient is high, radiation proof, every magnetic, reduce external interference, class of safety protection is high.
Description of drawings
Below in conjunction with concrete legend, the utility model is described further.
Fig. 1 is the structural representation of a kind of high frequency switch power water-cooled transformer of utility model.
Fig. 2 is the perspective view of Fig. 1.
Specific embodiments
As depicted in figs. 1 and 2, comprise magnetic core 4, radiating copper sheet 1, output copper coin 3, wherein radiating copper sheet 1 is the anaerobic copper sheet, the top of radiating copper sheet 1 is welded with water inlet pipe and outlet pipe, radiating copper sheet 1 is crimped on magnetic core 4 surfaces, elementary copper enamelled wire 5 is wound on radiating copper sheet 1, and magnetic core 4 becomes fixed form by 3 pairs of swagings of output copper coin, and transformer secondary output copper pipe 2 passes output copper coin 3 and magnetic core 4.
