Description
Technical Field
Embodiments of the present invention relate to a voltage transformation device.
Background
A transformer device is a device that transforms an electrical voltage into a voltage required by a corresponding electrical product. The two sides of the transformer device are provided with connecting pins for electric movement, and the electricity is input or output through the connecting pins. The core component installed on the transformer device is not provided with other components for restricting the core component to move to the side surface, so the installation of the core component is unstable. In addition, the height of the secondary winding portion of the coil is relatively low, which causes a problem of an increase in operating temperature. In addition, conventionally, a coil is wound around a core, and heat generation of the core and heat generation of the coil are increased, and although the coil can be used, the coil needs to be thicker in practice, which causes a problem of increase in cost.

Fig. 6 is a diagram showing a winding state of the first coil and the second coil in the voltage converting device according to the embodiment of the invention.
Referring to fig. 6, the first coil 10 may be wound on the outside of the first winding body part 121. Here, since the winding protrusion 121a is provided on the outer peripheral surface of the first winding body 121, the first coil 10 is wound around the outer surface of the winding protrusion 121a on the outer side of the first winding body 121. At this time, the first coil 10 is spaced apart from the first core member 106-1 by the projection length W of the winding protrusion 121a, as compared with the case where the first coil is directly wound on the outer peripheral surface of the first winding body portion 121.
That is, in the embodiment of the present invention, the spaced distance between the first coil 10 and the first core member 106-1 can be secured also in correspondence with the protruding length W of the winding protrusion 121a, thus making it possible to prevent heat generation of the first coil 10 from being superimposed on heat generation of the first core member 106-1, improving the temperature characteristics.
Further, as the extension portions 125 are formed on both sides of the first cover portion 123, the first coil 10 is wound outside the first extension portion 125-1. That is, by the first extension part 125-1, it is made possible to increase the winding area of the first coil 10 in the height direction in the first main body part 102, and therefore, the outer diameter of the first coil 10 after winding is reduced, and the area of the first coil 10 in contact with air is increased, so that the temperature characteristic of the first coil 10 can be improved.
Further, the first coil 10 is wound outside the first coil body portion 121 and the first extension portion 125-1, so that the height of the first coil 10 to be wound is increased and the outer diameter thereof is reduced, and therefore, the same effect can be obtained even with a smaller number of coils as compared with the case where the first coil 10 is wound only outside the first coil body portion 121, so that the production cost can be saved.
Further, as the first extension 125-1 extends upward from both sides of the first cover part 123, the second extension 125-2 extends horizontally at the end of the first extension 125-1, and the upper surface of the second extension 125-2 is spaced apart from the upper surface of the first cover part 123 by a first length D1. Here, the first length D1 is set to be equal to or less than the second length D2 corresponding to the thickness of the first core member 106-1, so that the movement of the first core member 106-1 in the horizontal direction on the first cover part 123 can be restricted by the extension part 125.
The second coil 20 may be wound outside the second bobbin part 141. The second coil 20 may be wound around the outside of the second bobbin part 141 between the second cover part 143 and the second base part 145. Although not shown, one or more winding protrusions may be provided on the outer peripheral surface of the second winding body portion 141.
Fig. 7 is a plan view of a first body portion in a transformer apparatus according to an embodiment of the present invention.
Referring to fig. 7, the first core insertion hole 127 may be provided in the first body portion 102 so as to vertically penetrate the first body portion 102. The first core insertion hole 127 may be provided in a size corresponding to the first core raised portion 106-1b of the first core member 106-1.
Wherein, the first body portion 102 may further include an expansion opening 129 formed at one side of at least one of the first core insertion holes 127. In an exemplary embodiment, the expansion opening 129 may be formed at both sides of the first core insertion hole 127. The expansion opening 129 may be provided to extend from both sides of the first core insertion hole 127. Accordingly, the flared opening 129 may form a spaced-apart space between the first core lobe 106-1 b. The expansion opening 129 may be provided from the first cover portion 123 in a direction perpendicular to the direction in which the extension portion 125 extends.
The width W1 of the expansion opening 129 may be provided narrower than the width W2 of the first core insertion hole 127. Further, the expanded opening 129 may be provided with hooking ribs 129a at both ends in the width direction. The movement of the first core protrusion 106-1b toward the expansion opening 129 side is restricted by the catch ridge 129 a.
In this case, one or more expansion openings 129 are formed at one side of the first core insertion hole 127, so that a heat dissipation area can be secured against heat generated from the first coil 10 and the first core member 106-1, and a heat release effect can be enhanced, thereby making it possible to improve the temperature characteristics of the transformer apparatus 100.
In the embodiment of the present invention, the heat release efficiency of the transformer apparatus 100 can be improved by securing the distance between the coil and the core member and securing the heat dissipation area by expanding the opening, thereby improving the temperature characteristics, and thus enabling the use of higher power than that used before under the same specification. Also, the diameter of the coil can be reduced while using the power that was used originally, so that the manufacturing cost can be reduced.
Fig. 8 is a graph comparing the temperature effects of the transformer apparatus according to the embodiment of the present invention and the conventional transformer apparatus.
Referring to fig. 8, it was confirmed that the temperature of the core member and the coil of the conventional transformer device was 73.7 ℃ (fig. 8 (a)), and that the temperature of the core member and the coil of the transformer device according to the example of the present invention was 69.9 ℃, and the temperature difference was about 4 ℃ (fig. 8 (b)).
While representative embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the embodiments described above, but should be determined with reference to the appended claims along with their full scope of equivalents.
