[0025] The present invention is further described below in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1 As shown, the SMX waterproof, high-temperature-resistant, high-performance energy storage transformer module includes: an aluminum shell 100, a potting compound 200, a transformer body 300, a transformer lead wire 400, a terminal 500 and a bushing 600. The transformer body 300 is connected to the inside of the aluminum shell 100 through the potting compound 200, one end of the transformer lead wire 400 is connected to the transformer body 300, and the other end of the transformer lead wire 400 is connected to the terminal 500, and the bushing 600 connects the transformer lead wire 400 and the terminal 500.

[0029] like Figure 2 As shown, the transformer body 300 includes: a first magnetic component 310, a second magnetic component 320, a third magnetic component 330, an inductor winding 340, a transformer winding 350 and a power line 360. The first magnetic component 310, the second magnetic component 320 and the third magnetic component 330 are connected in sequence. The inductor winding 340 is arranged in the first magnetic component 310, and the transformer winding 350 is arranged in the second magnetic component 320 and the third magnetic component 330. The transformer winding 350 is connected to the power line 360.

[0030] like Figure 4 As shown, the first magnetic component 310, the second magnetic component 320 and the third magnetic component 330 include: an upper magnetic core 311, a first gasket 312, a first magnetic sheet 313, a second gasket 314, a second magnetic sheet 315, a third gasket 316 and a lower magnetic core 317, and the upper magnetic core 311, the first gasket 312, the first magnetic sheet 313, the second gasket 314, the second magnetic sheet 315, the third gasket 316 and the lower magnetic core 317 are connected in sequence from top to bottom.

[0031] The heat dissipation coefficient of potting compound 200 is 2.0.

[0032] like Figure 5As shown, the transformer lead wire 400 is wrapped with an enameled wire 410 and an insulating adhesive 420 , the enameled wire 410 is a multi-strand enameled twisted wire, and the insulating adhesive 420 is a PET film or a polyimide film PI or a Teflon film PTFE.

[0033] like Figure 3 As shown, the inductor winding 340 includes: an inductor core 341 and an inductor coil 342 , and the inductor core 341 is connected to the inductor coil 342 .

[0034] like Figure 1 and 3 As shown, the transformer winding 350 includes: a transformer core 351, a primary coil 352 and a secondary coil 353. The primary coil 352 and the secondary coil 353 are respectively located on both sides of the transformer core 351. The primary coil 352 is connected to the power line 360, and the secondary coil 353 is connected to the transformer lead line 400.

[0035] The principle of the utility model is to wind the inductor coil 342 onto the inductor core 341, and wind the primary coil 352 and the secondary coil 353 onto the transformer core 351. When the device is turned on and used, the resistance of the device can be changed to improve the safety of the device; the first magnetic component 310, the second magnetic component 320 and the third magnetic component 330 are connected in sequence, and then the inductor winding 340 and the transformer winding 350 are connected to reduce the overall volume of the device; the transformer body 300 is sealed inside the aluminum shell 100 with the potting glue 200. When the device is powered on, water will not penetrate into the inside through the gap, and the device has strong waterproof and moisture-proof functions; the aluminum shell 100 can effectively dissipate heat from the working device.

[0036] The innovation of the utility model is that we add an insulating tape to the surface of ordinary enameled wire, so that the wire body can achieve the insulation effect of three-layer insulated wire. In this way, the wires of the primary and secondary sides of the transformer have the effect of three-layer insulated wire, and have good windability to achieve higher insulation requirements. The tape wrapped in this embodiment is a polyimide film PI that complies with UL, and a single layer can have an insulation withstand voltage of more than 5000V. The potting glue 200 uses silicone potting that can dissipate heat, and the space gaps of the product are filled. The potting glue 200 complies with UL requirements and has a high insulation resistance, and the heat dissipation coefficient is 2.0; through testing, it is found that the withstand voltage requirement of the product before and after potting is increased by more than 1.2 times. The above purpose is to allow the primary and secondary sides to pass through the transformer lead wire 400, and through the combination of high insulation and potting, the performance of the transformer lead wire 400 is improved, thereby realizing the direct lead-out of the transformer lead wire 400. The traditional structure adopts terminal lead-out, and the disadvantage of terminal lead-out is that the insulation distance is insufficient. However, the utility model realizes flying wire lead-out, and the surface distance and creepage distance of the primary and secondary sides become very large; therefore, a large insulation distance is achieved.

[0037] In order to achieve the above advantages, the utility model needs to solve two problems: temperature and core loss. The improvement of the above structure increases the internal temperature and increases the burden on the core. In order to solve the temperature problem, the heat dissipation coefficient of the potting glue 200 of the utility model is 2.0, which can directly reduce the internal temperature from 160°C to 120°C. The potted shell adopts an aluminum shell design, which has a good heat dissipation effect. Then the first magnetic component 310, the second magnetic component 320 and the third magnetic component 330 adopt a segmented structure, and the interior is divided into three independent structures by the first gasket 312, the second gasket 314 and the third gasket 316, forming a middle column segmented air gap structure, thereby reducing the core loss and the core temperature.

[0038] Compared with the traditional technology, the utility model is beneficial to improving the insulation of the device by improving the installation structure of the device; the magnetic parts are potted in the aluminum shell by potting glue, which improves the waterproof and moisture-proof ability of the device and has a good heat dissipation effect.

[0039] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
