Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating equipment, and in particular to a stable combined high-power induction heating device. Background Technology
[0002] Traditional induction heating equipment, especially high-power models, often faces numerous problems. On the one hand, their internal structure design is relatively simple and dispersed, and the layout lacks rationality. This not only results in a large overall size of the equipment, occupying too much production space, but also in long and complex wiring, which seriously affects the operational stability and heating efficiency of the equipment. To address this, a stable, modular high-power induction heating equipment is proposed. Utility Model Content
[0003] This utility model addresses the fact that current equipment or existing technologies lack suitable devices to solve the aforementioned problems. In practice, existing devices often have simple, scattered internal structures with an unreasonable layout, severely impacting operational stability and heating efficiency. This invention provides a stable, modular, high-power induction heating device with an integrated design, reasonable layout, spatial isolation, reduced space requirements, high integration, reduced line losses, and enhanced stability, effectively solving the problems mentioned in the background section.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows:
[0005] A stable, combined high-power induction heating device includes a housing, the interior of which is divided into a power supply area, a control area, and an integration area. An induction heating head is provided on the top of the housing, and a heating space is formed inside the induction heating head. The two side walls of the induction heating head have inlet and outlet ports. The induction heating head is sealed to a water inlet pipe and a water outlet pipe. The other ends of the water inlet pipe and the water outlet pipe are sealed to the water inlet and outlet system of the integration area. A control panel is movably connected to the housing, and the control area is divided into two functional zones.
[0006] The functional area is the area where the outer and inner layers separate the control area.
[0007] The outer plate has multiple interconnected wire slots, with a control switch and a control main board inside the wire slots, and multiple IGBT driver boards below the wire slots.
[0008] The inner layer board is connected to a circuit section, and a capacitor busbar is connected above the circuit section. A driver board is used below the capacitor busbar to connect multiple IGBT modules together. The IGBT modules are mounted on a water-cooled water box, and the other side of the water-cooled water box is connected to the inner layer board. An output board is connected below the IGBT modules.
[0009] The other end of the output board enters the integration area and connects with multiple output capacitors before entering the induction heating furnace head.
[0010] The power supply area includes a positive on / off contactor, which is connected to a three-phase bridge rectifier. The three-phase bridge rectifier is connected to the negative output, and the other end of the three-phase bridge rectifier is connected to an AC contactor. The other end of the AC contactor is the power input line.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] The interior of the casing is divided into multiple dedicated areas, each carrying different functions. The highly integrated design not only effectively simplifies the complex wiring and minimizes line loss, but also improves overall stability from the root. At the same time, through scientific and reasonable layout planning, the spatial boundaries of each area are clear and isolated from each other, minimizing mutual interference and ensuring smooth and efficient operation in all aspects.

[0019] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figure 1-4 As shown, this utility model provides a stable combined high-power induction heating device, including a housing 1. The housing 1 is internally divided into a power supply area 4, a control area 3, and an integration area 14. An induction heating head 2 is provided on the top of the housing 1. A heating space 6 is formed inside the induction heating head 2. The two side walls of the induction heating head 2 are provided with a feed inlet 5 and a discharge outlet 18. The induction heating head 2 is sealed to a water inlet pipe 16 and a water outlet pipe 17. The other end of the water inlet pipe 16 and the water outlet pipe 17 is sealed to the water inlet and outlet system of the integration area 14. A control panel 12 is movably connected to the housing 1. The control area 3 is divided into two functional areas.
[0021] The internal space of the housing 1 is divided into a power supply area 4, a control area 3, and an integration area 14, which are rationally arranged to ensure the efficient and stable operation of the equipment. An induction heating furnace head 2 is set on the top of the housing. The furnace head 2 forms a heating space 6 inside, and the feed inlet 5 and the discharge outlet 18 are opened on the two side walls of the furnace head 2 to facilitate the entry and exit of materials and realize a continuous heating operation process. The furnace head 2 is reliably sealed to the water inlet pipe 16 and the water outlet pipe 17. The other end of the water inlet pipe 16 and the water outlet pipe 17 are also sealed to the water inlet and outlet system in the integration area 14. This forms a complete and efficient water circulation cooling system to ensure the stability and safety of the equipment during long-term high-power operation. In addition, the housing 1 and the control panel 12 are connected in a movable manner. The control area 3 is divided into two functional areas.
[0022] The functional area is the area where the outer layer plate 26 and the inner layer plate 25 separate the control area 3.
[0023] To reduce space and achieve high integration, the control area 3 is physically separated into two functional areas using an outer layer board 26 and an inner layer board 25, based on its complex control function requirements. This ensures that the control area 3 can stably and efficiently control the entire induction heating equipment, further improving the reliability and stability of the equipment. It also enables the equipment to maintain excellent performance even under high-power operation, meeting the needs of various industrial production and other application scenarios with stringent requirements for heating accuracy and efficiency.
[0024] The outer plate 26 is provided with multiple interconnected wire grooves 29. The inner circle of the wire grooves 29 is provided with a control switch 7 and a control main board 8. Multiple IGBT driver boards 9 are provided below the wire grooves 29.
[0025] To reduce line loss and enhance stability, multiple interconnected wire grooves 29 are provided on the outer layer board 26. The interconnected wire grooves 29 make the connection between different lines more flexible and convenient, and allow for diverse wiring options according to actual circuit layout requirements. This effectively avoids the problems of line crossing and tangling, thereby greatly improving the rationality and neatness of the line layout and laying the foundation for reducing space occupation. The inner ring of the wire groove 29 is equipped with a control switch 7 and a control main board 8. Placing the control switch 7 and the control main board 8 in the inner ring of the wire groove can minimize the length of the connection lines between them and other related circuit components, reduce line resistance, thereby reducing line loss and improving power transmission efficiency. Multiple IGBT driver boards 9 are located below the wire groove 29.
[0026] The inner layer board 25 is connected to a circuit section 24. A capacitor busbar 28 is connected above the circuit section 24. A drive board 10 is used below the capacitor busbar 28 to connect multiple IGBT modules 11 together. The IGBT modules 11 are mounted on a water-cooled water box 27. The other side of the water-cooled water box 27 is connected to the inner layer board 25. An output board 13 is connected below the IGBT modules 11.
[0027] In this device, the inner layer board 25 is connected to the circuit section 24, and above the circuit section 24, there is a capacitor busbar 28. Multiple IGBT modules 11 located below the capacitor busbar 28 are connected into a whole by the drive board 10. These IGBT modules 11 are mounted on the water-cooled water box 27, and the other side of the water-cooled water box 27 is connected to the inner layer board 25. In addition, the output board 13 is connected below the IGBT modules 11. All the components work closely together to form a complete structural system to achieve specific electrical functions and performance requirements, and ensure the stable operation and efficient work of the entire device.
[0028] The other end of the output board 13 enters the integration area 14 and is connected to multiple output capacitors 15 before entering the induction heating furnace head 2.
[0029] After entering the specific integration area 14, one end of the output board 13 is connected to multiple output capacitors 15. The connected circuit extends further and eventually enters the interior of the induction heating furnace head 2, thus forming a complete energy transmission path. This provides the necessary conditions for the normal operation of the induction heating furnace head 2 and ensures the stable and efficient operation of the entire heating system.
[0030] The power supply area 4 includes a positive on / off contactor 19, which is connected to a three-phase bridge rectifier 20. The three-phase bridge rectifier 20 is connected to a negative output 21. The other end of the three-phase bridge rectifier 20 is connected to an AC contactor 23, and the other end of the AC contactor 23 is a power input line 22.
[0031] like Figure 5 As shown, in power supply area 4, the positive contactor 19 controls the on / off state of the circuit and is connected to the three-phase bridge rectifier 20 to rectify the current. The three-phase bridge rectifier 20 is not only connected to the negative output 21 to form a complete current output circuit, but its other end is also connected to the AC contactor 23. The AC contactor 23 further controls and distributes the current, while the other end of the AC contactor 23 is connected to the power input line 22.
[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
