The utility model can enable the cooling water to cool the lead fully by the hollow copper rod and the cooling water pipe, has a high cooling efficiency, guarantee the high frequency transformer to work safely and reliably; reduces unnecessary maintenance and replacing to the high frequency transformer in working process, and prolongs the service life.
Description
Technical field
The utility model relates to transformer, relates in particular to the high-power high-frequency transformer that has cooling structure.
Background technology
Along with the continuous development and progress of power electronics control technology, high frequency transformer is being brought into play more and more important effect in high-frequency energy transmission, coupling, filtering field.The rated output voltage of high frequency transformer can reach several kilovolts, and therefore in the course of the work, the coil bag can produce a large amount of heats.If can not well eliminate these heats, then may damage high frequency transformer, shorten its expected service life even it can not be worked.
In the type of cooling of existing high frequency transformer, external refrigeration water enters in the middle hollow copper rod of high frequency transformer through water supply connector, cooling water flows to the water out adapter of the hollow copper rod other end along the waterway channel at hollow copper rod center, links to each other with the external refrigeration water circulation system again.Adopt this kind type of cooling to cool off the center of coil bag, can't be effectively the integral body of the coil bag of high-power high-frequency transformer be dispelled the heat, cooling effectiveness is low.
The content of utility model
The applicant is not good at radiating effect in the existing high frequency transformer use, and easily the problem of heating is studied and improved, and another kind of high frequency transformer is provided, and its high cooling efficiency makes the work that high frequency transformer can be safe and reliable.
The technical solution of the utility model is as follows:
A kind of high frequency transformer, comprise cylindrical shell 9, cylindrical shell 9 middle devices have hollow copper rod 2, hollow copper rod 2 is fastened on the cylindrical shell 9 by water supply connector 1, the outer wall of cylindrical shell 9 is provided with binding post 7, hollow copper rod 2 upper units have water out adapter 3, ferrite magnetic material 5 is installed in the cylindrical shell 9 and is placed on the hollow copper rod 2, lead 6 spiral surroundings are on ferrite magnetic material 5, cooling water pipe 4 and lead 6 staggered being looped around side by side on the ferrite magnetic material 5, one end of cooling water pipe 4 is connected with water out adapter 3, and the other end of cooling water pipe 4 leads to cylindrical shell 9 outsides.
Useful technique effect of the present utility model is:
Cooling water pipe of the present utility model and lead are staggered to be looped around on the ferrite magnetic material side by side, and cooling water can fully cool off lead by hollow copper rod and cooling water pipe, and the cooling effectiveness height makes the work that high frequency transformer can be safe and reliable.Reduce maintenance and replacing unnecessary in the high frequency transformer course of work, prolonged its useful life.
Description of drawings
Fig. 1 is that the master of the utility model internal structure looks schematic diagram.
Fig. 2 is the schematic top plan view of the utility model internal structure.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As depicted in figs. 1 and 2, high frequency transformer comprises a cylindrical shell 9, cylindrical shell 9 middle devices have hollow copper rod 2, hollow copper rod 2 is fastened on the cylindrical shell 9 by the water supply connector 1 of band screw socket, the outer wall of cylindrical shell 9 is provided with binding post 7, hollow copper rod 2 upper units have water out adapter 3, ferrite magnetic material 5 is installed in the cylindrical shell 9 and is placed on the hollow copper rod 2, lead 6 spiral surroundings are on ferrite magnetic material 5, the connector lug of lead 6 passes the connection radio-frequency generator from the hole of cylindrical shell 9 bottoms, with epoxy glue 8 cast, hollow copper rod 2 tops link to each other with the main frame inductive head respectively with binding post 7 in the cylindrical shell 9; Spiral surrounding is on ferrite magnetic material 5 alternately successively for cooling water pipe 4 and lead 6, and an end of cooling water pipe 4 is connected with the water out adapter 3 on hollow copper rod 2 tops, and the other end of cooling water pipe 4 leads to the cooling water recirculation system of cylindrical shell 9 outsides.
During work, lead 6 is connected with the external high frequency generator, input high-frequency high voltage and current, lead 6 produces magnetic field around the back on ferrite magnetic material 5, the high-frequency high voltage and current is converted into the high-frequency low-voltage current to be delivered on the hollow copper rod 2, the positive and negative electrode that forms the high frequency transformer output respectively at the top and the afterbody of hollow copper rod 2, the afterbody of hollow copper rod 2 links to each other with cylindrical shell 9, negative pole is by 7 outputs of the binding post on the cylindrical shell 9, and the top of hollow copper rod 2 links to each other with the external host inductive head respectively with binding post 7.
Meanwhile, external refrigeration water enters hollow copper rod 2 through water supply connector 1 connection, cooling water just can flow to water out adapter 3 along the waterway channel at hollow copper rod 2 centers, then along be connected cooling water pipe 4 on the water out adapter 3 on ferrite magnetic material 5 with the water side of spiral surrounding mode following current to cooling water pipe 4, link to each other with the external refrigeration water circulation system again, shown in the direction of arrow among the figure.Thereby in the high frequency transformer course of work, form continual cooling heat dissipation effect, reduced high frequency transformer owing to generate heat in the course of work and caused unnecessary maintenance and replacing, prolonged its useful life.
The above only is a preferred implementation of the present utility model, is appreciated that those skilled in the art under the prerequisite that does not break away from spirit of the present utility model and design, can make other improvement and variation.
