However, in industrial applications, where temperatures are typically high and the heat dissipation capacity of the heating power supply is poor, this negatively impacts the heating efficiency. Utility Model Content

[0004] In view of this, an embodiment of the first aspect of the present invention provides an electromagnetic induction heating power supply.

[0005] A second aspect of this utility model provides an electromagnetic induction heating system.

[0006] To achieve the above objectives, an embodiment of this utility model provides an electromagnetic induction heating power supply, comprising: a housing, wherein a middle plate extending along the height direction is provided inside the housing, the middle plate dividing the space inside the housing into a first chamber and a second chamber; an induction circuit board, disposed in the first chamber and connected to the middle plate, one end of the induction circuit board being connected to an input cable, the other end of the induction circuit board being used to connect at least two output cables, at least two inverter modules being provided on the induction circuit board, one end of each output cable being connected to an inverter module, and the other end of each output cable being used to connect to an electromagnetic heating plate; and a heat sink, disposed in the second chamber, the heat sink being positioned opposite to the inverter modules; wherein, the top wall of the first chamber is provided with a first air inlet, and the opposite side walls of the first chamber are provided with first air outlets, the first air inlet and the first air outlet forming a first air duct, the top wall of the second chamber is provided with a second air inlet, and the bottom wall of the second chamber is provided with a second air outlet, the second air inlet and the second air outlet forming a second air duct, and the first air duct and the second air duct being independent of each other.

[0007] According to the electromagnetic induction heating power supply proposed in this utility model, through a reasonable air flow path design, the heat of the inverter module can be quickly and effectively absorbed and discharged by the heat sink, thus maintaining the reliable operation of the equipment.

[0008] Specifically, the electromagnetic induction heating power supply includes a housing, a middle plate, an induction circuit board, and a heat sink. The housing provides overall mechanical protection, ensuring that the internal components are protected from the external environment. The middle plate extends along the height direction, dividing the interior of the housing into two chambers, namely a first chamber and a second chamber. By separating the functional areas, the induction circuit board and the heat sink can function effectively within their respective chambers, while the middle plate also serves as the contact surface for the heat sink, aiding in heat conduction. Furthermore, because the various structures are spatially divided according to their functions, precise problem location can be achieved when maintenance is required due to a malfunction, reducing unnecessary disassembly procedures.

[0009] The system features a first air duct that allows air to flow laterally through the top intake and side exhaust of the first chamber, and a second air duct that allows air to flow vertically through the top intake and bottom exhaust of the second chamber. The two air ducts are independent of each other, which significantly improves the uniformity of airflow and the flexibility of control. This system is suitable for industrial equipment that requires independent airflow adjustment in multiple zones, ensuring that the environment of each chamber is stable and does not interfere with each other, thereby improving the overall system performance and process quality.

[0010] The induction circuit board, located in the first chamber, processes the input electrical signals and drives the electromagnetic heating plate.

[0018] The panel, together with the fixed plate, base, and cover, forms the first chamber. Combined with a detachable plate located at one end of the fixed plate and opposite the induction circuit board, this design achieves a balance between structural stability and ease of maintenance.

The cable interface is mounted on another side panel forming the first chamber, positioned opposite the start / stop terminals on a different side panel for easy wiring and connection. It provides power input and signal transmission channels for connection to external devices via aviation plug cables.

[0026] In some technical solutions, the middle plate optionally includes: a lower partition, a main partition, and a connecting partition arranged along the height direction, wherein the connecting partition is located at the end of the main partition away from the base, and the lower partition is located at the end of the main partition close to the base; wherein the sensing circuit board includes a driving board and at least two capacitor boards, the capacitor boards are electrically connected to an inverter module, the capacitor boards are connected to the main partition, and the driving board is connected to the connecting partition.

[0027] In this technical solution, the middle plate, through the design of the lower partition, main partition, and connecting partition, not only provides structural support but also optimizes the layout and connection method of the components.

The sensing circuit board includes a separate drive board and two or more capacitor boards. The drive board is located at the top and connected to the connecting partition, while the multiple capacitor boards are located in the middle and connected to the main partition. The capacitor boards are mainly used to connect to the inverter module to connect the output cables. The rational distribution of the capacitor boards and drive board ensures the separation of the electrical functional area and the control area, enhancing the stability and operational accuracy of the equipment. The installation positions of the rectifier bridge and inverter module make power conversion and management more efficient, while the design of the drive board ensures accurate transmission of control signals.

[0028] In some technical solutions, optionally, the inverter module includes two inverter modules, which are electrically connected to a rectifier bridge for connecting to an input cable. One end of each capacitor board is connected to the two inverter modules of the same inverter module, and the other end of the capacitor board is connected to an output cable. The driver board is electrically connected to the inverter modules.

[0029] Each inverter module includes two inverter modules connected to a rectifier bridge. The inverter modules are connected to the output cables via a capacitor board. The rectifier bridge rectifies AC power into DC power and is connected to the input cables. The inverter modules, connected to the rectifier bridge, can invert DC power into high-frequency AC power and are also connected to the capacitor board, which is connected to the output cables.

[0030] Optionally, the rectifier bridge is placed between the two inverter modules, achieving a reasonable electrical layout and an efficient energy conversion path. The rectifier bridge is responsible for the rectification function at the input end, while the inverter modules are responsible for the inversion function at the output end. The two work together to ensure the stable and efficient operation of the electromagnetic induction heating system.

[0031] In some technical solutions, the heat sink may optionally include: heat sink fins, wherein the heat sink fins and the main partition are an integral structure.

[0032] In this design, the heat sink is an integral structure consisting of the heat sink and the main partition. By integrating the heat sink onto the main partition, the heat sink can be directly installed on the middle plate, effectively reducing the heat transfer path and improving the heat dissipation effect on the inverter module.

[0033] In some technical solutions, the cable port may optionally include: at least one input port and at least two output ports, with the input port located between the two output ports, and the input port being used for input cables to pass through, and the output ports being used for output cables to pass through.

[0034] The cable routing port includes an input port and output ports. The input port is used for input cables to pass through and is located between two output ports. Multiple output ports are used for output cables to pass through and are distributed on both sides of the input port or along the cable. The input port, located between two output ports, forms the cable entry area, and the output ports are for output cables to exit, ensuring a clear cable path.

[0035] By passing the input cable between the two output ports, the input and output cable paths are effectively separated, preventing them from crossing or tangling. The cables are neatly arranged along a predetermined path, facilitating maintenance and repair. By rationally positioning the cable outlets, mutual interference between the input cables and the inverter module's output cables is reduced, improving the system's electromagnetic compatibility.

[0036] Optionally, the cable tray is equipped with a sealed structure to prevent dust and water damage, ensuring the safety of internal electronic components. Cables pass through a dedicated channel, simplifying cable connection and replacement processes.

[0037] By passing the input cable between the two output ports, the inverter module cable has a dedicated exit path, which optimizes cable routing management, improves equipment reliability and maintenance convenience, and helps reduce electromagnetic interference.

[0038] In some technical solutions, the system may optionally include: a signal board, which is stacked on top of the driver board and is communicatively connected to the signal board; and a small board, which is located on the inverter module and is communicatively connected to the driver board.

[0039] In this technical solution, the electromagnetic induction heating power supply achieves a higher level of control and signal processing capabilities through the rational layout and connection of the signal board and the small board. The stacked design of the signal board not only saves space but also improves the efficiency and reliability of signal processing.

[0040] In some technical solutions, the system may optionally include: lamp holes located on the housing; and a lamp board electrically connected to the signal board, wherein the lamp board is provided with multiple signal lights corresponding to the lamp holes.

[0041] In this technical solution, the design of the lamp holes and lamp panels provides an intuitive status indication system for the electromagnetic induction heating power supply. Users can directly understand the operating status of the equipment through the indicator lights, thereby improving the convenience and safety of operation. The electrical connection between the lamp panel and the signal panel ensures timely signal transmission, enabling the equipment to react quickly and indicate status changes. Through this design, the user interface of the equipment is optimized, enhancing the user experience and operability of the equipment.

[0042] In some technical solutions, the system may optionally include: a first fan located in the first chamber and detachably connected to the top plate; a fan bracket located in the second chamber and abutting against the connecting partition; and a second fan located on the fan bracket and positioned between the radiator and the top plate.

[0043] In this technical solution, the heat dissipation capacity of the electromagnetic induction heating power supply is significantly improved through the rational layout and installation of the fans. The fans force airflow, rapidly removing heat from the radiator and ensuring the equipment maintains a stable temperature even under high load conditions. The fan placement design allows cool air to flow effectively through the radiator, optimizing heat exchange efficiency and reducing the risk of performance degradation or failure due to overheating. The connection between the fans and the power system ensures operational reliability and flexibility, enabling dynamic temperature adjustment of the equipment according to actual needs.

[0044] The first fan is located in the first chamber and is detachably connected to the top plate. The first fan is responsible for the airflow and circulation within the first chamber. Its detachable connection to the top plate facilitates installation, maintenance, and replacement. This improves the uniformity of airflow and ventilation efficiency within the first chamber.

[0046] The second fan is installed on the fan bracket, located between the radiator and the top plate. It is responsible for the airflow inside the second chamber or equipment, especially the air exchange near the radiator. By being set between the radiator and the base, it effectively pushes the cooling air through the radiator, improves the heat dissipation efficiency, enhances the cooling effect of the radiator, and prevents the equipment from overheating.

[0047] In some technical solutions, the housing may optionally be rectangular, and the inverter module and the heat sink may be detachably connected to the side wall facing the first chamber.

[0048] In this technical solution, the electromagnetic induction heating power supply achieves a balance between compactness and functionality through the rectangular design of the housing and the rational layout of the inverter module and heat sink. The detachable connection between the inverter module and the heat sink not only facilitates installation and maintenance but also enhances the equipment's heat dissipation capacity, ensuring stability under high load operation. The overall design improves the reliability and service life of the equipment while providing users with greater ease of operation and maintenance.

Detailed Implementation

[0055] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0056] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0057] The following reference Figures 1 to 10 Some embodiments according to the present invention are described.

[0058] like Figure 1 and Figure 2 As shown, this embodiment provides an electromagnetic induction heating power supply 100. Through a reasonable airflow path design, it ensures that the heat from the inverter module 1061 can be quickly and effectively absorbed and discharged by the radiator 108, maintaining the reliable operation of the equipment.

[0059] Specifically, the electromagnetic induction heating power supply 100 includes a housing 102, a middle plate 104, an induction circuit board 106, and a heat sink 108. The housing 102 provides overall mechanical protection and shielding, ensuring that internal components are protected from external environmental influences. The middle plate 104 extends along the height direction, dividing the interior of the housing 102 into two chambers, as shown below. Figure 4 and Figure 7 As shown, the circuit is divided into a first chamber 1022 and a second chamber 1024. By separating the functional areas, the induction circuit board 106 and the heat sink 108 can function in their respective chambers. At the same time, the chamber 1022 also serves as the contact surface for the heat sink 108, helping to conduct heat. In addition, since the various structures are spatially divided according to their functions, precise problem location can be achieved when maintenance is required due to a fault, reducing unnecessary disassembly procedures.

[0060] The first chamber 1022 houses the induction circuit board 106 and related components disposed on the induction circuit board 106, such as the inverter module 1061, providing an electrical functional area for electrical signal processing and conversion to drive the electromagnetic heating plate 202. The second chamber 1024 houses the heat sink 108 and its related heat dissipation components, providing a thermal management area to dissipate the heat generated by the inverter module 1061 through airflow and heat conduction. Specifically, the first chamber 1022 has a first air duct; the top wall of the first chamber 1022 has a first air inlet 1102, and the opposite side walls have first air outlets 1104, forming a first air duct between the first air inlet 1102 and the first air outlet 1104. The second chamber 1024 has a second air duct; specifically, the top wall has a second air inlet 1106, and the bottom wall has a second air outlet 1108, forming a second air duct between the second air inlet 1106 and the second air outlet 1108. The first and second air ducts are independent of each other and do not interfere with each other.

[0061] The air intake and exhaust of the first air duct are mainly achieved through top intake and side exhaust. Air enters the first chamber 1022 from the top and flows to the air outlets on both side walls, forming a lateral flow. The air outlets on the side walls of the first chamber 1022 are used to achieve uniform air distribution and exhaust. The air flow path is short and uniform, which is conducive to the uniform distribution of temperature or airflow in the first chamber 1022. It is suitable for uniform cooling or heating of materials or equipment in the first chamber 1022, reducing dead zones and improving airflow circulation efficiency.

[0062] The second air duct's air intake and exhaust are primarily achieved through a top-intake, bottom-outflow system. Air enters from above and exits through the bottom wall outlet, forming a vertically downward airflow channel suitable for top-to-bottom air exchange or temperature regulation. Utilizing gravity-assisted airflow promotes gas exchange within the second chamber 1024, facilitating the removal of hot air or impurities from the bottom of the chamber, enhancing convection, and improving air quality or temperature uniformity within the second chamber 1024.

[0063] The two duct systems have independent physical or airflow paths and do not interfere with each other. The airflow parameters (air volume, temperature, pressure, etc.) of the two chambers can be controlled separately, improving the system's flexibility and control accuracy.

[0064] In summary, this solution forms a first air duct with horizontal flow through the top air intake and side air outlet of the first chamber 1022, and a second air duct with vertical flow through the top air intake and bottom air outlet of the second chamber 1024. The two air ducts are independent of each other, which significantly improves the uniformity of airflow and control flexibility. It is suitable for industrial equipment that requires independent airflow adjustment in multiple zones, ensuring that the environment of each chamber is stable and does not interfere with each other, thereby improving the overall system performance and process quality.

[0065] The induction circuit board 106 is located in the first chamber 1022 and is responsible for processing the input electrical signals and driving the electromagnetic heating plate 202. The induction circuit board 106 is equipped with two or more inverter modules 1061, which can convert the electrical energy transmitted through the input cable and then transmit it to the electromagnetic heating plate through the output cable to achieve electromagnetic heating. Specifically, the inverter module 1061 can convert electrical energy into electromagnetic energy for heating.

[0066] Inverter modules 1061 are mounted on induction circuit boards 106, with each module connected to an electromagnetic heating plate 202. The modules invert direct current (DC) into high-frequency alternating current (AC), driving the electromagnetic heating plate 202 to generate heat. A heat sink 108 is located in the second chamber 1024, attached to the middle plate 104, directly absorbing the heat generated by the inverter modules 1061. Through its attachment to the middle plate 104, the heat sink 108 effectively conducts heat away.

[0067] By connecting the induction circuit board 106 to the middle plate 104, the induction circuit board 106 can be stably installed. The position of the inverter module 1062 is opposite to the heat sink 108 to facilitate heat transfer. The close contact between the heat sink 108 and the middle plate 104 ensures that the heat sink 108 can effectively absorb the heat of the inverter module 1062 and conduct it to the outside through the middle plate 104.

[0068] In summary, through this design, the electromagnetic induction heating power supply 100 can achieve efficient heat dissipation while ensuring equipment performance.

[0069] Optionally, the electromagnetic induction heating power supply 100 includes a total of one input cable, one rectifier bridge 1068, four inverter modules 1062, two capacitor banks 1064, and two output cables. The input cable is connected to the rectifier bridge 1068, and the output of the rectifier bridge 1068 is connected to the four inverter modules 1062. Every two inverter modules 1062 form an inverter module 1061, and each inverter module 1061 is connected to a capacitor bank 1064. Each capacitor bank 1064 is connected to an output cable. Dual-output control is possible, allowing simultaneous control of two electromagnetic heating plates 202, or one output cable can be used to power on while the other is powered off.

[0070] In some embodiments, the housing 102 may optionally include two connected structures: a base 1032 and a cover plate 1034. The base 1032 serves as the basic structure and is located at the bottom of the overall device. It is connected to the side plate 1036 of the cover plate 1034 by a fixing device to form the basic frame of the housing 102.

[0071] A second air outlet 1108 and a cable passage 1033 are provided on the base 1032. The second air outlet 1108 enables the second chamber to exhaust air to the outside, while the cable passage 1033 is used for the introduction and connection of cables and lines to ensure that the electrical components of the first chamber 1022 can be connected to an external power supply and control system.

[0072] The second air outlet 1108 is connected to the second chamber 1024, providing cold air into the chamber to help the radiator 108 dissipate heat.

[0073] The cover plate 1034 is used to close the upper part of the equipment and protect the internal components. It is specifically set above the base 1032 and is detachably connected to the base 1032.

[0074] Optionally, the cover plate 1034 can be connected to the base 1032 by bolts or clips for easy maintenance and repair.

[0075] The cover plate 1034 includes a top plate 1035 and a side plate 1036. The top plate 1035 is disposed opposite to the base 1032 to form the top of the housing 102. The side plate 1036 connects the top plate 1035 and the base 1032 to form the side of the housing 102. The first air outlet 1104 communicates with the first chamber 1022 and is located on the side plate 1036 as a hot air outlet to ensure airflow and heat dissipation.

[0076] Through the design of the base 1032 and cover 1034, the housing 102 not only provides robust mechanical support, but also achieves electrical connection and thermal management through the cable port 1033 and the second air outlet 1108. The cable port 1033 on the base 1032 ensures the effective transmission of electrical signals.

[0077] The removable design of the cover plate 1034 makes equipment maintenance and repair more convenient, while the one-piece molding of the top plate 1035 and side plates 1036 enhances the overall strength and durability of the housing 102. Through these designs, the housing 102 can provide protection while optimizing the heat dissipation and electrical functions of the equipment, achieving efficient electromagnetic induction heating.

[0149] The air intake plate 310 is assembled with the radiator 108 and the base 1032 and is a component of the air duct.

[0150] The cable sleeve 306 is installed on the cable pass 1033 on the base 1032 and serves to protect the cable. The second fan 1186 is mounted on the fan bracket 1184 to provide airflow to the heat sink 1082 in the second air duct. The air flows out from the air outlet of the base 1032, making its heat dissipation better.

[0151] An axial flow fan, namely the second fan 1186, is installed on the fan bracket 1184 and is finally fixed on the cover plate 1034.

[0152] The first fan 1182 is installed inside the first air inlet 1102 of the cover plate 1034 to provide air source for the first air duct.

[0154] In summary, this design solves the problems of large size and low protection level of electromagnetic induction heating power supplies. In terms of size, it modularizes the internal components, facilitating disassembly and maintenance. For heat dissipation, it employs a dual-airflow system. The first airflow is a T-shaped side-exit duct, while the second is a straight, vertically penetrating duct. This dual-airflow system effectively increases heat dissipation efficiency. Furthermore, dust covers are added to the air inlets of the airflow ducts, ensuring not only heat dissipation but also providing some waterproofing and dustproofing. The entire casing of the induction heating power supply is connected by welding and screws to form a shielded cavity, and grounding bolts are installed on the casing to effectively shield against external interference signals, enhancing its anti-interference capability.

The second air duct is in the shape of an inverted T-shaped side exhaust, which has uniform heat dissipation and effectively dissipates heat for internal components. 5. Modular design, easy to disassemble and maintain; 6. The panel consists of two parts: a fixed panel that is fixed to the support plate, and a detachable panel that can be removed to allow wiring. The fixed panel is fixed to the support plate to prevent operator error and risk of electric shock. 7. The product is highly efficient and energy-saving, requires no maintenance, is safe and reliable, has a long lifespan, provides accurate temperature control, has high insulation performance, and improves the working environment.
