[0023] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.
[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0025] Example 1
[0026] like Figures 1-4 As shown, this embodiment provides a transformer that reduces leakage flux and improves heat dissipation efficiency, including a frame 1 and a core column 2. The frame 1 has a cavity 4, and the top and bottom walls of the cavity 4 are provided with through holes 5. The core column 2 is provided with through holes 6. The core column 2 is placed in the cavity 4, and the through holes 6 correspond to the through holes 5.
[0027] In this embodiment, through holes 5 are opened on the top and bottom walls of the frame 1, and through holes 6 are opened in the middle of the magnetic core column 2. Through holes 6 correspond to through holes 5. The heat generated by the magnetic core column 2 is discharged through through holes 6 and through holes 5, thereby improving the heat dissipation efficiency.
[0028] In this embodiment, the cavity 4 has open notches 7 on its side walls. All four side walls of the cavity 4 in this embodiment have open notches 7. With these open notches 7 on all four side walls of the cavity 4, heat from the magnetic core pillar 2 can be dissipated through the notches 7. The four notches 7, together with the through hole 5, form five heat dissipation channels, allowing heat to be dissipated from both the center and surrounding areas of the magnetic core pillar 2, greatly improving heat dissipation efficiency.
[0029] In this embodiment, a coil assembly is wrapped around the circumferential wall of the magnetic core pillar 2. Wrapping the coil assembly around the magnetic core pillar 2 in this embodiment reduces magnetic leakage flux.
[0030] In this embodiment, the top wall of the coil assembly contacts the top wall of the cavity 4, and the bottom wall of the coil assembly contacts the bottom wall of the cavity 4. There is a gap between the top wall of the magnetic core pillar 2 and the top wall of the cavity 4, and a gap also exists between the bottom wall of the magnetic core pillar 2 and the bottom wall of the cavity 4. The gaps between the top and bottom walls of the magnetic core pillar 2 and the top and bottom walls of the cavity 4 allow heat from the top and bottom walls of the magnetic core pillar 2 to pass through these gaps and be conducted to the through-hole 5, where it is discharged. This rapid heat dissipation further improves heat dissipation efficiency.
[0031] In this embodiment, the coil group includes multiple longitudinally stacked coils 3.
[0032] The coil group described in this embodiment includes three coils 3.
[0033] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
