A kind of water-cooled high frequency transformer
Technical field
The utility model relates to a kind of high frequency transformer, specifically is meant a kind of water-cooled high frequency transformer.
Background technology
High frequency transformer is as the topmost part of Switching Power Supply.Topological structure in the Switching Power Supply has a lot.Such as the semibridge system circuit for power conversion; Two switch modules take turns conducting and produce the high-frequency impulse alternate electric energy of 10kHz-100KHz during work; Carry out transformation through high frequency transformer then; The output AC electricity, the number of turn ratio of each winding coil of high frequency transformer has then determined the height of output voltage.Transformer is the device of conversion alternating voltage, electric current and impedance, when being connected with alternating current in the elementary coil, just produces exchange flux in the iron core (or magnetic core), makes and induces voltage in the secondary coil.
The making of high frequency transformer is a high frequency electric source, the critical component on the high-power high-frequency power-supply device especially, and it is little how to be made into volume, and ampacity is big, and lightweight high-power high-frequency transformer is that it makes one of difficult point.It is to adopt water-cooled that present high frequency transformer has part; Its structure is two independently halfbodies of doing of aluminium or copper; Draw respectively in two independently block halfbodies and dig out cylindrical cavity half, two semicolumn cavitys constitute integral body, and a newel is arranged in this integral body; In center annular, place transformer core and former limit winding; In two halfbodies, offer C type water route respectively and use water cooling, two openends in C type water route connect outside water inlet pipe and outlet pipe respectively, so that carry out cooling heat transferring independently.Its shortcoming is: the such transformer of 1 processing, and the copper of handy equal size or aluminium ingot are drawn and are dug out such shape, carry out Surface Machining again and get out water route UNICOM in inside to get final product, and the waste of copper or aluminium ingot is bigger, and difficulty of processing is also big; 2 weight are big, and volume is big, are difficult to miniaturization, and 3 turn ratioes are always N:1, can not change use according to actual needs; In 4 uses water is required than higher, 90 degree are turned many, and easy blocking influences heat exchange, and failure rate is high.
The utility model content
The purpose of the utility model is to provide a kind of water-cooled high frequency transformer, when solving transformer water-cooled problem, reduces its volume and weight, reaches miniaturization, purpose cheaply.
The purpose of the utility model realizes through following technical proposals:
A kind of water-cooled high frequency transformer comprises copper base, and iron core is installed on copper base, and primary coil is installed on iron core, and secondary coil is installed on iron core, and said secondary coil is the copper pipe of boring, and the boring of copper pipe is a water-cooling channel.Copper base comprises three copper coins, has insulation board to separate between every copper coin, and one of them is as carrying the mainboard that iron-core coil is installed, and one of which end back protruding upward is to extending below; Also can directly extend out, portion forms connecting portion endways, and connecting portion is provided with pilot hole, in two sides of mainboard; All be connected with a mounting panel, on connecting portion, also be provided with pilot hole, three copper coins link to each other with a back level element respectively, and the effect that version is installed is to keep the position of mainboard installation iron core unsettled; Guaranteeing its heat-sinking capability, also is the output of electric current simultaneously, and therefore, the horizontal plane of mounting panel part is connected with mainboard is overlapping; To extending below, form connecting portion behind 90 ° of the last outwards foldings after turning down 90 ° then, connecting portion is provided with pilot hole, and iron core is fixedly mounted on the mainboard of copper base; Primary coil is wrapped on the iron core, on iron core, also is wound with secondary coil, after the two ends energising of rim coil, according to the magnetoelectricity rule; On secondary coil, form alternating voltage, i.e. the transformation process of alternating voltage, in this process, core interior forms magnetic flux; On secondary coil, be reduced to electric current, iron core periphery and secondary coil do not have good heat exchange, will accumulate a large amount of heats and cause fault, have just limited the ampacity of transformer; Can gain in weight again and cost if increase conductive section, thereby influence own vol and the stress that bears the diode of its weight, therefore, the cylindrical shape copper pipe that adopts cavity structure is as secondary coil; Its inner cavity is as the cooling duct, during use, with the inside feeding cooling water of copper pipe; Electric energy after the outside output of the copper pipe transformation, cooling water is taken away the heat that the transformation process produces, and has reduced the temperature of iron core and secondary; When having improved its current capacity, also reduce own vol and born the diode stress of its weight, just reduced equipment failure rate accordingly.
On described copper pipe, be enclosed with copper foil layer.Further say,, attach one deck Copper Foil, form stable induced magnetic fields in the outside of copper pipe in order to overcome the leakage field problem that produces because of the copper pipe structure.
Said copper pipe passes copper base and is fixed on the copper base.Further say,, make things convenient for secured core in order to improve exchange capability of heat further, the mode that adopts copper pipe to pass copper base, what iron core can be firm is installed on the copper base, and the heat of copper base also can be passed to cooling water, improves its heat radiation and renders a service.
Between said copper base and iron core, insulation board is installed.Further say,, between copper base and iron core, insulation board is installed in order to improve the security performance after the integral installation.
The utility model compared with prior art has following advantage and beneficial effect:
A kind of water-cooled high frequency transformer of 1 the utility model, the cylindrical shape copper pipe that adopts cavity structure is as secondary coil, and its inner cavity is as the cooling duct; During use; The inside of copper pipe is fed cooling water, the voltage after the copper pipe output transformation, cooling water is taken away the heat that copper pipe produces; Also reduce the temperature of iron core, improved its current capacity;
A kind of water-cooled high frequency transformer of 2 the utility model, water pipe replace drawing the method for digging with aluminium ingot or copper ingot, have not only reduced difficulty of processing, and have reduced production cost;
A kind of water-cooled high frequency transformer of 3 the utility model; Water pipe replaces drawing the method for digging with aluminium ingot or copper ingot, has further dwindled volume, has realized the miniaturization of high frequency transformer; Reduce the transformer own wt simultaneously, also just reduced its mechanical stress inner and associated devices.
