Description

Technical Field

[0001] This utility model relates to the field of transformer device technology, specifically to an IT medical isolation transformer device. Background Technology

[0002] In today's highly information- and intelligent medical field, IT medical isolation transformers play an indispensable role as key power equipment ensuring the stable and safe operation of medical devices. They effectively isolate electrical interference between medical equipment and the power supply system, preventing damage to precision medical equipment caused by voltage fluctuations, harmonic pollution, and other power issues, thereby ensuring the accuracy and reliability of medical diagnosis and treatment. With the rapid development of medical technology and the emergence of various advanced medical devices, these devices place increasingly stringent demands on the stability and purity of the power supply. IT medical isolation transformers need to operate continuously for extended periods to meet the needs of these medical devices. During this process, the transformer inevitably generates a large amount of heat due to resistive losses, hysteresis losses, and eddy current losses caused by current flowing through the windings and core. If this heat cannot be dissipated in a timely and effective manner, the internal temperature of the transformer will continue to rise.

[0003] Currently, most common IT medical isolation transformer devices adopt an integrated design for heat dissipation. The heat dissipation components are connected to the transformer body by non-removable fixing methods such as welding and riveting. Although this design is relatively simple during initial installation, in actual use, when the heat dissipation structure fails, such as a damaged cooling fan or blocked heat dissipation fins, it is often necessary to disassemble or replace the entire transformer device because it is not easy to remove the heat dissipation structure from the transformer body for repair or replacement. This not only increases maintenance costs and time, but may also cause medical equipment to be shut down for a long time, affecting normal medical work. Utility Model Content

[0004] The purpose of this utility model is to provide an IT medical isolation transformer device to solve the problem mentioned in the background art. Currently, the heat dissipation structure of common IT medical isolation transformer devices mostly adopts an integrated design. The heat dissipation components are connected to the transformer body by non-removable fixing methods such as welding and riveting. Although this design is relatively simple during initial installation, in actual use, when the heat dissipation structure fails, such as a damaged cooling fan or blocked heat dissipation fins, it is not easy to remove the heat dissipation structure from the transformer body for repair or replacement. Often, the entire transformer device needs to be disassembled or replaced. This not only increases maintenance costs and time, but may also cause medical equipment to be shut down for a long time, affecting normal medical work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an IT medical isolation transformer device, comprising a transformer body, wherein mounting grooves are provided at the top and bottom of the rear side of the transformer body, and mounting plates are provided at the top and bottom of the rear side of the transformer body, the front side of the mounting plate extends into the interior of the mounting groove and engages with the mounting groove, and engaging grooves are provided at the rear of the transformer body corresponding to the top and bottom of the mounting groove, and engaging plates are fixedly connected to the rear of the top and bottom of the mounting plates, the side of the engaging plate away from the mounting plate extending into the interior of the engaging groove and engaging with the engaging groove, an inner rear plate one is fixedly connected at the top and bottom of the rear of the transformer body, an inner rear plate two is fixedly connected at the center of the rear of the transformer body, and a heat-absorbing fan is fixedly installed at the center of the rear of the mounting plate, the input end of the front side of the heat-absorbing fan is connected to an air suction pipe, the front side of the air suction pipe extends into the interior of the transformer body, and the output end of the rear side of the heat-absorbing fan is connected to an air outlet pipe.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This IT medical isolation transformer device features a mounting plate that penetrates through the front side of the mounting plate into the mounting groove of the transformer body and engages with it. The top and bottom engaging plates of the mounting plate penetrate through the engaging groove at the rear of the transformer body and engage with it. Simultaneously, the fixing plates on the engaging plates penetrate through the fixing grooves of inner rear plates one and two and engage with them. The positioning blocks on the mounting plate penetrate through the positioning grooves of inner rear plates one and two and engage with them. The engaging plates are threadedly connected to the transformer body via fixing bolts. This structural design allows for a detachable connection between the heat dissipation structure and the transformer body. When the heat dissipation structure malfunctions, such as a damaged heat absorption fan, only the fixing bolts need to be removed to disconnect the threaded connection between the engaging plates and the transformer body. Then, the connections between the mounting plate and the mounting groove, the engaging plates and the engaging grooves, the fixing plates and the fixing grooves, and the positioning blocks and the positioning grooves can be disconnected sequentially. The snap-fit ​​connection allows the mounting plate, along with the heat absorber fan, to be removed from the transformer body for repair or replacement without disassembling or replacing the entire transformer unit. This significantly reduces maintenance costs and time, minimizes downtime for medical equipment due to maintenance, and ensures the normal operation of medical work. Because the heat dissipation structure is detachable, when cleaning is required, operators can follow the disassembly steps described above to remove the mounting plate and heat absorber fan from the transformer body. A thorough and meticulous cleaning of the heat absorber fan, its intake and exhaust pipes, and other components is then performed to remove surface dust, impurities, and any accumulated dirt. This ensures the heat dissipation performance of the structure remains optimal, effectively reducing the internal temperature of the transformer body and guaranteeing the stable operation of the IT medical isolation transformer device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: an IT medical isolation transformer device, including a transformer body 1. Mounting grooves 8 are provided at the top and bottom of the rear side of the transformer body 1. Mounting plates 9 are provided at the top and bottom of the rear side of the transformer body 1. The front side of the mounting plate 9 extends into the interior of the mounting groove 8 and engages with it. Engaging grooves 10 are provided at the rear of the transformer body 1 corresponding to the top and bottom of the mounting groove 8. Engaging plates 11 are fixedly connected to the top and bottom of the mounting plate 9. The side of the snap-fit ​​plate 11 away from the mounting plate 9 extends into the interior of the snap-fit ​​groove 10 and snaps into the snap-fit ​​groove 10. The inner rear plate 1 5 is fixedly connected to the top and bottom positions of the inner rear end of the transformer body 1. The inner rear plate 2 7 is fixedly connected to the center position of the rear end of the transformer body 1. The heat absorption fan 12 is fixedly installed at the center position of the rear end of the mounting plate 9. The input end of the front side of the heat absorption fan 12 is connected to the air suction pipe 6. The front side of the air suction pipe 6 extends into the interior of the transformer body 1. The output end of the rear side of the heat absorption fan 12 is connected to the air outlet pipe 13.

[0015] A base 2 is fixedly connected to the bottom of the transformer body 1, and side plates 4 are fixedly connected to both sides of the top of the base 2 corresponding to both sides of the transformer body 1.

[0016] Support legs 3 are fixedly connected to both sides of the bottom of the base 2.

[0017] The two inner rear plates 1 5 are symmetrically arranged. The top of the rear end of the inner rear plate 1 5 and the top and bottom of the rear end of the inner rear plate 2 7 are provided with fixing grooves 15. The two snap-fit ​​plates 11 are symmetrically arranged. The top of the front side of the snap-fit ​​plate 11 is fixedly connected to a fixing plate 16. The front side of the fixing plate 16 extends through the interior of the fixing groove 15 and snaps into the fixing groove 15.

[0018] Positioning grooves 17 are provided at the bottom of the rear end of the inner rear plate 1 5 and at the top and bottom of the rear end of the inner rear plate 2 7. Positioning blocks 18 are fixedly connected at the top and bottom of the front side of the mounting plate 9. The front side of the positioning block 18 extends into the interior of the positioning groove 17 and engages with the positioning groove 17.

[0019] The two sides of the rear end of the snap-fit ​​plate 11 are threaded with fixing bolts 14. The front side of the fixing bolts 14 penetrates into the interior of the transformer body 1 and is threadedly connected to the transformer body 1.

[0020] Working Principle: When the IT medical isolation transformer device starts working, the transformer body 1 generates heat due to resistance loss, hysteresis loss, and eddy current loss caused by current flowing through the windings, core, and other components. At this time, the heat absorption fan 12, which is fixedly installed at the rear center of the mounting plate 9, starts running. The input end of the heat absorption fan 12 is connected to the suction pipe 6, which extends into the transformer body 1. The heat absorption fan 12 draws in the hot air from inside the transformer body 1 through the suction pipe 6. The output end of the heat absorption fan 12 is connected to the outlet pipe 13. The hot air drawn into the heat absorption fan 12 is then... Under the action of the air outlet 13, the heat is discharged to the outside of the transformer body 1, thereby dissipating the heat inside the transformer body 1, reducing the internal temperature of the transformer body 1, and ensuring that the transformer body 1 can operate stably in a suitable temperature environment. When installing the heat dissipation structure, the positioning block 18 on the front side of the mounting plate 9 plays a positioning role. The installer aligns the positioning block 18 with the positioning groove 17 at the bottom of the rear end of the inner rear plate 5 and the top and bottom of the rear end of the inner rear plate 7 inside the transformer body 1, so that the front side of the positioning block 18 penetrates into the positioning groove 17 and engages with the positioning groove 17. This step ensures that the mounting plate 9 is in place. Accurate positioning during installation provides the foundation for subsequent snap-fit ​​and fixing operations. After positioning, the front side of the mounting plate 9 is inserted into the mounting groove 8 at the top and bottom of the rear side of the transformer body 1, and the mounting plate 9 is snapped into the mounting groove 8. At the same time, the snap-fit ​​plate 11, which is fixedly connected to the top and bottom rear sides of the mounting plate 9, extends through the side away from the mounting plate 9 into the snap-fit ​​groove 10 at the top and bottom rear sides of the mounting groove 8 at the rear end of the transformer body 1, and snaps into the snap-fit ​​groove 10. In addition, the front side of the fixing plate 16, which is fixedly connected to the top of the front side of the snap-fit ​​plate 11, extends through the top of the rear end of the inner rear plate 1 5 and the top of the rear end of the inner rear plate 2 7. The heat dissipation structure is initially fixed to the transformer body 1 by engaging with the fixing groove 15 inside the top and bottom of the plate 11. To further ensure the stability of the heat dissipation structure, fixing bolts 14 are used for final fixing. The front side of the fixing bolts 14, which are threaded to the rear end of the plate 11 near both sides, passes through the inside of the transformer body 1 and is threaded to the transformer body 1, thereby firmly fixing the heat dissipation structure to the transformer body 1. This ensures that the heat dissipation structure will not loosen or fall off due to vibration or other reasons during the operation of the transformer body 1, and ensures that it can continuously and stably dissipate heat for the transformer body 1.

[0021] In summary: This IT medical isolation transformer device has a mounting plate 9 that penetrates through the front side into the mounting groove 8 of the transformer body 1 and engages with it. The top and bottom engaging plates 11 of the mounting plate 9 penetrate through the engaging groove 10 at the rear end of the transformer body 1 and engage with it. Simultaneously, the fixing plate 16 on the engaging plate 11 penetrates through the fixing grooves 15 of the inner rear plate 1 and the inner rear plate 2 and engages with it. The positioning block 18 on the mounting plate 9 penetrates through the positioning grooves 17 of the inner rear plate 1 and the inner rear plate 2 and engages with it. The engaging plate 11 is threadedly connected to the transformer body 1 by fixing bolts 14. This structural design allows for a detachable connection between the heat dissipation structure and the transformer body 1. When the heat dissipation structure malfunctions, such as when the heat absorption fan 12 is damaged, only the fixing bolts 14 need to be removed to release the threaded connection between the engaging plate 11 and the transformer body 1. Then, the mounting plate 9 and the mounting groove 8, the engaging plate 11 and the engaging groove 10, and the fixing plate 11 can be sequentially disconnected. The engagement between mounting plate 9 and fixing slot 15, and positioning block 18 and positioning slot 17, allows the mounting plate 9, along with the heat absorption fan 12, to be removed from the transformer body 1 for maintenance or replacement. This eliminates the need to disassemble or replace the entire transformer unit, significantly reducing maintenance costs and time, minimizing downtime for medical equipment, and ensuring the normal operation of medical work. Because the heat dissipation structure is detachable, when cleaning is required, operators can follow the disassembly steps described above to remove mounting plate 9 and heat absorption fan 12 from the transformer body 1. A thorough and meticulous cleaning of the heat absorption fan 12, its suction pipe 6, and exhaust pipe 13 is then performed to remove surface dust, impurities, and any accumulated dirt, ensuring the heat dissipation performance of the structure remains optimal, effectively reducing the internal temperature of the transformer body 1, and guaranteeing the stable operation of the IT medical isolation transformer unit.
