Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and specifically relates to a novel structure for a high-efficiency heat dissipation mode of a high-power transformer. Background Technology

[0002] Most high-power transformers on the market are bulky and rely on methods such as adding thermal paste or water cooling for heat dissipation. This results in high material costs and large space requirements, making the products uncompetitive in the market. The heat dissipation structure design of this utility model is simple in structure and small in size, does not require additional material costs, and can significantly improve heat dissipation efficiency. It is also simple to manufacture and saves system space and material costs. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a novel structure for a high-efficiency heat dissipation mode of a high-power transformer, comprising two magnetic cores. Each magnetic core includes a magnetic column disposed on the side of the magnetic core, with the two magnetic columns abutting each other. Each magnetic column has a through hole. Each magnetic column includes a core center column with segmented air gaps and a ceramic plate. The ceramic plate is fixedly disposed on the air gap of the core center column and at the point where the two magnetic columns abut each other. A frame is disposed on the outside of the magnetic column. The frame is made of NOMEX material, and a coil is wound around the outside of the frame. The two ends of the coil are insulated from the two magnetic cores.

[0004] Preferably, the magnetic core and the coil are fixed to the bottom plate.

[0005] Preferably, the coil is made of LITZS wire.

[0006] Preferably, an insulating film is fixedly disposed between the coil and the magnetic core.

[0007] This utility model has the following beneficial effects: 1. The transformer of this utility model increases air convection by setting through holes on the magnetic core and increasing air duct openings. In actual applications with temperature differences or active heat dissipation, it can increase air convection in the transformer and accelerate the air convection inside the transformer itself, thus speeding up the removal of heat from the transformer. In high-power applications, it can improve the heat dissipation efficiency of the transformer, save system space, and improve the reliability of the transformer. Furthermore, the magnetic core column is divided into segments with air gaps, and ceramic plates with good heat dissipation performance are used between the air gaps, which further improves the heat dissipation efficiency of the transformer.

[0008] 2. The skeleton of this utility model is made of NOMEX material, which not only can insulate the coil and the magnetic core, but also, because the material is thin, it occupies less space as a skeleton, which can save transformer space, making the overall structure of the magnetic core more compact and further reducing the size of the transformer.

[0009] 3. The transformer of this utility model is fixed on the bottom plate, which makes it easy to grab and install the transformer on the circuit board, thus improving the applicability of the transformer. Attached Figure Description

[0012] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0013] This invention provides a novel structure for a high-power transformer with an efficient heat dissipation mode, which has a highly efficient ventilation and heat dissipation effect, such as... Figure 1-5 As shown, it includes two magnetic cores 1, each magnetic core 1 including a magnetic post 2, the magnetic post 2 being disposed on the side of the magnetic core 1, the two magnetic posts 2 abutting each other, and a through hole being provided in the middle of the magnetic post 2, which can form air convection, dissipate the heat inside the magnetic core 1, and improve the heat dissipation efficiency of the transformer. The magnetic column 2 includes a magnetic core column 3 with segmented air gaps and a ceramic plate 4. The ceramic plate 4 is fixedly disposed on the air gap of the magnetic core column 3 and at the point where the two magnetic columns 2 abut. A frame 5 is disposed on the outside of the magnetic column 2. The frame 5 is made of NOMEX material, which occupies little space and can reduce the size of the transformer. A coil 6 is wound around the outside of the frame 5. The coil 6 is made of LITZS wire and can withstand large current. The two ends of the coil 6 are insulated from the two magnetic cores 1 by an insulating film 7. Then, the two magnetic cores 1 and the coil 6 are fixed to the bottom plate 8 with adhesive to facilitate the gripping of the transformer for installation on the circuit board. The shape and opening position of the bottom plate 8 are determined by the circuit board installation requirements.

[0014] The above embodiments are merely illustrative of the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of this utility model.
