Technical Field

[0001] This utility model relates to the field of transformers, specifically to an improved U-shaped transformer structure. Background Technology

[0002] With the increasing global demand for energy, the need for and promotion of power conversion has reached a new peak. There is a need for more environmentally friendly and healthier power sources, higher reliability, higher efficiency, smaller size, reduced losses, lower costs, and recyclability. As the functions of electrical equipment become more sophisticated, power conversion for these new applications requires not only more efficient physical conversion, greater power, and higher current, but more importantly, a small, safe, and reliable magnetic device.

[0003] Current transformers require insulating material to be wound around the magnetic core and a frame for fixation. This presents unavoidable problems regarding heat dissipation and stability. Furthermore, the traditional structure limits the development of automation.

[0004] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0016] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] Example 1

[0018] Figure 1 This is a schematic diagram of the structure of this utility model.

[0019] like Figure 1 As shown, an improved U-shaped transformer includes: a coil 100, insulating paper 200, a magnetic core 300, an air vent 400, and a base 500. The coil 100 and the magnetic core 300 are disposed within the base 500, the insulating paper 200 is disposed within the coil 100, the surface of the magnetic core 300 is coated with epoxy, the air vent 400 is connected to the magnetic core 300, and the coil 100 is connected to the magnetic core 300 through the insulating paper 200.

[0020] The magnetic core 300 includes a first magnetic core 310 and a second magnetic core 320. The first magnetic core 310 and the second magnetic core 320 have a U-shaped structure. The top ends of the first magnetic core 310 and the second magnetic core 320 are connected to each other, and the bottom ends of the first magnetic core 310 and the second magnetic core 320 are connected to each other. An air pad 400 is provided at the connection between the first magnetic core 310 and the second magnetic core 320.

[0021] The coil 100 includes a first coil 110 and a second coil 120, which are respectively connected to a first magnetic core 310 and a second magnetic core 320.

[0022] The innovation of this invention lies in the fact that the coil 100 does not require an additional cumbersome insulating material wrapping, allowing it to directly contact the air, maximizing the heat dissipation area and resulting in better heat dissipation. This is achieved by adding an epoxy coating to the outer layer of the coil 100.

[0023] In this invention, the frame structure is eliminated, reducing both cost and size. The underlying principle is the improvement of the traditional E-shaped magnetic core into a symmetrical U-shaped magnetic core. Traditional magnetic cores require a frame to support and position the coil, providing both insulation and structural support. This invention uses two U-shaped magnetic cores assembled together to form a closed magnetic circuit. This structure allows the coil to be wound directly around one side of the U-shaped magnetic core. When the two U-shaped magnetic cores are assembled, the coil is fixed in position. The U-shaped structure itself serves as a support for the coil. The coil 100 can be directly wound around the first magnetic core 310 and the second magnetic core 320. Then, by assembling the first magnetic core 310 and the second magnetic core 320, the coil is fixed in the middle. Simultaneously, epoxy coating solves the insulation problem, and the U-shaped assembly structure solves the support problem.

[0024] Beyond the aforementioned performance improvements, the most important aspect is that this structure can be manufactured using automated equipment. Traditional structures, with their E-shaped core and frame, suffer from space constraints, hindering the free movement of the winding head. This invention employs an open structure, allowing the winding head to freely approach and wind. Traditional cores require preparation followed by frame installation, winding, insulation treatment, and final assembly. This invention, however, allows direct winding, epoxy coating, and assembly. Therefore, compared to traditional structures, this invention offers several advantages in assembly: simplified structure (eliminating the frame reduces assembly complexity); integrated process (epoxy coating simultaneously addresses insulation and curing); geometric optimization (the U-shaped open structure facilitates automated equipment operation); and standardized design (identical U-shaped cores facilitate mass production using automated methods).

[0025] Compared with traditional technology, this invention features an epoxy coating on the surface of the magnetic core, eliminating the need for additional insulation materials and improving heat dissipation; the magnetic core adopts a U-shaped combined structure, eliminating the need for a keel structure, reducing size and cost; and the above structure enables automated winding, improving production efficiency.

[0026] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
