It features an iron core as the main body, with a primary coil wound around it. A secondary coil is located outside the primary coil, consisting of a connecting tube, a connecting copper plate, and a connecting post assembly. A terminal block assembly receives the primary current, and the connecting post assembly outputs the secondary current through the terminal block assembly. The terminal block assembly, connecting block assembly, primary coil assembly, connecting tube, connecting copper plate, connecting post assembly, and iron core are molded together with resin to form an integrated transformer.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0021] Example 1: Please see Figure 1 - Figure 3 This is the first embodiment of the present invention. This embodiment provides a novel quenching transformer, comprising: 1. Housing 1, top cover 3, mounting plate 4, and partition plate 6; top cover 3 is fastened to the top side of housing 1. Mounting plates 4 are symmetrically fixed on both sides of the housing 1. The partition 6 is located at the middle position inside the housing 1. Heat dissipation assembly 2, fixing assembly 5, and transformer assembly 7; Heat dissipation components 2 are located on both sides of the housing 1. The fixing components 5 are symmetrically arranged at both ends of the top side of the housing 1. The transformer assembly 7 is located inside the housing 1.

[0022] Specifically, the heat dissipation component 2 includes a cavity 21, a heat dissipation plate 22, heat dissipation fins 23, a cooling groove 24, and a conduit 25. The cavity 21 is opened inside the housing 1. The heat dissipation plate 22 is fixed on both sides of the housing 1. The heat dissipation fins 23 are evenly fixed on the sides of the heat dissipation plate 22. The cooling groove 24 is opened inside the heat dissipation plate 22. The conduit 25 is symmetrically fixed on both sides of the heat dissipation plate 22. The top of the inner side of the heat dissipation plate 22 is connected to the top of the inner side of the cavity 21 through the top conduit 25. The bottom of the inner side of the heat dissipation plate 22 is connected to the bottom of the inner side of the cavity 21 through the bottom conduit 25.

[0023] Furthermore, through the conduits 25 at the top and bottom of both sides of the heat sink 22, the coolant after heating can be transported from the top conduit 25 to the inside of the heat sink 22, and after cooling down, the coolant is transported back to the inside of the cavity 21 through the bottom conduit 25, thereby realizing automatic circulation. In the case of excessive transformer temperature.

[0024] In use, the cavity 21 and the inner side of the heat sink 22 are filled with coolant or transformer oil. When the transformer assembly 7 inside the cavity 21 is running, it generates heat, which is transferred to the coolant, causing it to heat up and flow upward. The heated coolant is then transported to the cooling tank 24 inside the heat sink 22 through the top conduit 25. Then, with the help of the heat dissipation fins 23, the heat in the coolant is transferred to the air, causing the coolant inside the cooling tank 24 to cool down and flow downward. After that, it is transported back to the inner cavity 21 of the housing 1 through the bottom conduit 25. The heat generated by the transformer assembly 7 is transferred to the external environment through the circulating coolant, thereby realizing the function of automatic cooling and preventing the transformer from overheating and being damaged.

[0025] In summary, through the structure of the heat dissipation component 2 and the symmetrically arranged conduits 25 on both sides of the heat dissipation plate 22, the coolant in the inner cavity 21 of the housing 1 absorbs heat and circulates inside the cooling tank 24. With the cooperation of the heat dissipation fins 23, the heat is transferred to the external environment, realizing the function of automatic cooling, ensuring that the transformer is within the normal temperature range, and extending its service life.

[0026] Example 2: Please see Figure 4 - Figure 5 This is the second embodiment of the present utility model.

[0027] Specifically, the fixing component 5 includes an elastic locking block 51, a locking groove 52, a sealing groove 53, a sealing gasket 54, and a mounting hole 55. The elastic locking blocks 51 are symmetrically fixed at both ends of the top side of the housing 1. The locking groove 52 is provided at the middle position of both ends of the top cover 3. The mounting hole 55 is provided at the center of the side of the mounting plate 4. The elastic locking block 51 is fastened inside the locking groove 52. The sealing groove 53 is symmetrically provided at both ends of the bottom side of the top cover 3. The sealing gasket 54 is fixed inside the sealing groove 53.

[0028] Furthermore, the sealing gasket 54 inside the sealing groove 53 can prevent coolant leakage inside the housing 1, thus facilitating subsequent maintenance.

[0029] Specifically, the transformer assembly 7 includes an iron core 71, a coil 72, a positive terminal 73, and a negative terminal 74. The iron core 71 is symmetrically fixed at both ends of the bottom side of the top cover 3. A partition 6 is fixed at the middle position of the bottom side of the top cover 3. The coil 72 is wound on the iron core 71. The surface of the coil 72 is coated with insulating varnish. One end of the coil 72 passes through the top cover 3 and is fixed with the positive terminal 73. The other end of the coil 72 passes through the top cover 3 and is fixed with the negative terminal 74.

[0030] Furthermore, the transformer function is achieved by the cooperation of the iron core 71 and the coil 72. The insulating varnish on the surface of the coil 72 replaces the resin, which improves its heat conduction efficiency and prevents heat accumulation on its inner side, thus preventing damage to the transformer.

[0031] In use, the transformer can be installed in the required position with the cooperation of the mounting holes 55 on the side of the mounting plate 4. Before installation, the top cover 3 is fastened to the top side of the housing 1, so that the trapezoidal structure at the top of the elastic clip 51 is fastened to the inside of the slots 52 on both sides of the top cover 3, thus fixing the top cover 3 to the housing 1. At this time, with the cooperation of the sealing gasket 54, coolant leakage or external dust and impurities can be prevented from entering, facilitating subsequent maintenance. The positive terminal 73 and negative terminal 74 at both ends of the top side of the top cover 3 are connected to the circuit respectively. With the cooperation of the coil 72 and the iron core 71, the transformer function is realized. At the same time, by replacing resin with insulating varnish on the surface of the coil 72, its heat conduction efficiency can be improved, preventing heat accumulation on its inside. In summary, the structure of the fixing component 5 and the transformer component 7, and the structure of the elastic block 51 and the slot 52, allow for quick disassembly and assembly of the top cover 3, ensuring that its inner side is in a sealed environment while facilitating subsequent maintenance and replacement. The structure of the iron core 71 and the coil 72 allows them to directly contact the coolant, which can improve the heat dissipation efficiency of the transformer and extend its service life.
