Description
Technical field
The present invention relates to a kind of handheld coaxial list water route forced water cooling intermediate frequency transformer.
Background technology
Handheld coaxial forced is a kind of more advanced transformer, and that studies at home is less.There is certain problem in this type of transformer can found at present:
1. in the type of cooling, need employing two water routes, and the resistance in two water routes cannot be consistent usually, especially operationally there will be the HTHP phenomenon of local at the import and export of induction coil, passing through of serious obstruction cooling water flow; The cooling needs ensureing induction coil are difficult to when two water routes use same water source (i.e. a water pump), namely under same hydraulic pressure, most of water can flow through from a water route (inductive head water inlet pipe, copper sheathing, central tube, inductive head water return outlet), only have little a part of water to flow through from Article 2 water route (induction coil water inlet, right induction coil base, right induction coil contiguous block, left induction coil base, induction coil water return outlet), therefore forced water cooling effect will be had a greatly reduced quality.
2. because induction coil is main heat radiating structure, when temperatures as high after cooling water flow out of more than 100 degrees Celsius is (different according to putting watt level temperature outward, most Gao Shikeda about 300 degree), water pipe requires too high to external world, does not also have the water pipe that can be suitable for this position completely at present.
3. induction coil water inlet, right induction coil base and induction coil water return outlet, left induction coil base are for being welded to connect.Because welding is different by solder material, electrochemical reaction can occur very soon in using, structure cannot Long-Time Service herein.
4. because this structure needs the outside exposed of external water pipe, be easy to by damage during use, to be that HTHP is careless slightly will there is casualty accident to the water cut because of this place.
5. central tube welds with left induction coil base, and weld bond electrochemical reaction can occur, can not Long-Time Service; Because adding the operations such as thermal weld during making, be difficult to the perpendicularity both ensureing, thus cause follow-up installation difficulty, also the rate of finished products of processing cannot just be ensured, even and if successful installation, the weld because of this both structure is the position that pressure-bearing is subject to external force maximum, cannot ensure its Long-Time Service.
6. induction coil water return outlet and left induction coil base be weld often can cause coming off of induction coil water return outlet when completing the welding of central tube and left induction coil base.
7. right induction coil base and cylindrical shape copper sheathing are by being welded to connect, the electric current had up to more than 3000A to right induction coil base from cylindrical shape copper sheathing flows through, welding material known at present all cannot meet the needs of this position, through often causing weld bond loose contact because of current heating and damage after using; Right induction coil base and cylindrical shape copper sheathing have very rigorous matching requirements, because adding the operations such as thermal weld during making, are difficult to the accurate of cooperation position both ensureing; Because both are welding, the connection between them often can be caused to come off when the welding completing both.
8. inductive head water inlet pipe is used to interface that is that provide cooling water to total main body and that provide primary coil line, the line of primary coil is in same pipeline, the high-frequency current that the line of primary coil has up to about 150A in normal environment for use flows through, wire rod is caused to send a large amount of heats so just need water-cooling structure, but because when wire insulation inconsistent cannot ensure that it is under water for a long time, insulation breakage can not occur, once occur damagedly to cause short circuit by water because of it in same cooling water pipe.
Therefore, this kind equipment existing remains in certain deficiency, needs to improve, to improve its fail safe.
Summary of the invention
Object of the present invention, exactly for solving the problem, provides a kind of handheld coaxial forced, and it changes the problem that existing equipment adopts two water routes, and whole equipment only has a water route, simplifies the difficulty of assembling, improves fail safe.
For achieving the above object, the present invention adopts following technical scheme:
A kind of handheld coaxial list water route forced water cooling intermediate frequency transformer, it comprises supervisor, and install the central tube of hollow in supervisor, central tube outside is main winding; The rear end cap be tightly connected is provided with in supervisor rear end, rear end cap is provided with main water return tube and two water inlet pipes, the two-way inlet wire of the cavity connects of two water inlet pipes and supervisor main winding simultaneously penetrates respectively from two water inlet pipes, main water return tube then with central tube inner space; Cooling water enters supervisor by two water inlet pipes, the central tube of main winding front end is provided with the sealing water guide cover that band is porose, central tube front end is provided with the front nose circle lid be fixed with one, front nose circle covers the boss being provided with a semicircle, form one between front nose circle lid and sealing water guide cover and seal water cavity, the hole of water through sealing water guide cover enters sealing water cavity; Cover the water-guiding hole being provided with and being communicated with sealing water cavity at front nose circle, water-guiding hole is communicated with induction coil water inlet, and water enters induction coil thus; Central tube is also threaded with front end housing, and front end housing is semicircle, is coordinated by the semicircle boss of main insulation pad with front nose circle lid; Front end housing is provided with water guide inclined hole, and water guide inclined hole one end is communicated with induction coil delivery port, and the other end is communicated with central tube, and cooling water enters central tube thus, is finally flowed out by main water return tube, forms single water route methods for cooling; Induction coil is connected by fixture and front nose circle lid and front end housing.
Described rear end cap is connected with supervisor to be reinforced by pipe collar, and main water return tube and water inlet pipe are threaded with rear end cap.
Described fixture comprises the assembly of a pair symmetry, and assembly is assembled primarily of briquetting, bolt and block; The end of induction coil is connected on front nose circle lid and front end housing by two described briquettings and block.
Described water-guiding hole is communicated with induction coil inlet opening by the conduit pipe in front nose circle lid, and induction coil inlet opening is corresponding with induction coil water inlet.
Described water inlet pipe is divided into left water inlet pipe and right water inlet pipe, and symmetrical is distributed in main water return tube both sides.
Described central tube, front end housing, induction coil, front nose circle lid, supervisor and rear end cap form auxiliary winding.
Sealing rubber ring is provided with between described front nose circle lid and sealing water guide cover.
