Description

Technical Field

[0001] This utility model relates to the field of electromagnetic boiler technology, and in particular to a novel liquid-cooled electromagnetic boiler. Background Technology

[0002] An electromagnetic boiler is a heating device that converts electrical energy into heat energy using the principle of electromagnetic induction heating. It uses high-frequency current to generate an alternating magnetic field, which induction heats the metal container itself or the metal heating element, thereby heating water or other media. It is mainly used for heating, hot water supply or industrial heating, and belongs to a clean and energy-saving new type of electric boiler.

[0003] An electromagnetic heating controller is a device that converts ordinary AC / DC power into alternating voltage and current pulses. Internally, it uses an AC-DC-AC rectifier and inverter module as the main circuit, and is equipped with an oscillating coil and an excitation capacitor to adjust the amplitude and frequency of the output alternating voltage and current pulses. This causes an alternating magnetic field to be generated in the electromagnetic induction coil, forming an induced heating energy field. Metals within this parametric field will generate eddy currents due to electromagnetic induction, thereby achieving electromagnetic heating.

[0004] During this process, both the electromagnetic heating controller and the electromagnetic induction coil generate heat, but this heat contributes nothing to the electromagnetic heating itself and needs to be dissipated promptly to ensure stable low-temperature operation, resulting in energy waste. Previous electromagnetic heating systems mostly used air-cooling systems, where the heat generated by both components was dissipated into the air through airflow. Furthermore, through continuous exploration and experimentation with various heat dissipation devices for the controller, and the electromagnetic induction coil requiring high-temperature wires, a comprehensive improvement to the entire electromagnetic heating unit was necessary to ensure unobstructed heat dissipation. This increased the equipment's heat dissipation costs, and heat dissipation efficiency was still difficult to guarantee, leading to overheating alarms and shutdowns. High temperatures could even shorten the lifespan of electronic components, affecting the overall system's operational stability and lifespan. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a new type of liquid-cooled electromagnetic boiler.

[0006] This utility model is achieved through the following technical solution:

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0022] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Example 1: As shown in the figure, this utility model includes a cabinet, an electromagnetic heater and an electromagnetic heating controller 7 installed inside the cabinet. Its characteristic is that it further includes a circulating cooling pipeline for cooling the heat generated by the electromagnetic coil of the electromagnetic heater and the electromagnetic heating controller 7. The circulating cooling pipeline includes a circulating cooling water inlet pipe 2, a circulating cooling water outlet pipe 3, and a cooling hose 5. The electromagnetic heater includes a coil copper tube 6. The circulating cooling water inlet pipe 2 is connected to one end of the coil copper tube 6 via the cooling hose 5, and the circulating cooling water outlet pipe 3 is connected to the other end of the coil copper tube 6 via the cooling hose 5. The electromagnetic heating controller 7 includes a heat sink. The circulating cooling water inlet pipe 2 is connected to one side of the heat sink of the electromagnetic heating controller 7 via the cooling hose 5, and the circulating cooling water outlet pipe 3 is connected to the other side of the heat sink of the electromagnetic heating controller 7 via the cooling hose 5.

[0024] The circulating cooling pipeline also includes an inlet pipe 1 connected to the circulating cooling water inlet collection pipe 2 outside the cabinet, and an outlet pipe 4 connected to the circulating cooling water outlet collection pipe 3. The inlet pipe 1 is used to supply cooling fluid to the circulating cooling pipeline, and the temperature of the cooling fluid is between 20-40℃. The outlet pipe 4 is used to recover the cooling fluid from the circulating cooling pipeline, and the temperature of the cooling fluid is between 50-70℃. This application uses liquid cooling circulation. By controlling the circulating cooling flow rate and increasing the heat exchange area, the temperature of the electromagnetic heating controller 7 and the electromagnetic heating coil can be better controlled within 50-60℃, and the heat that would otherwise be lost can be recovered.

[0025] In this example, the electromagnetic heater preferably includes, but is not limited to, four sets of electromagnetic coils. The electromagnetic heating controller 7 is provided with four sets of coils. The circulating cooling water inlet pipe 2 and the circulating cooling water outlet pipe 3 are each provided with eight connectors, which are respectively connected to the coil copper pipe 6 of the electromagnetic heater and the heat sink of the electromagnetic heating controller 7 through the cooling hose 5.

[0026] Furthermore, the components in the electromagnetic heating controller 7 are mounted on a heat sink made of aluminum alloy with a multi-pass cavity structure for the flow of the cooling fluid. The circulating cooling water inlet pipe 2 is connected to the inlet of the heat sink via a cooling hose 5, and the circulating cooling water outlet pipe 3 is connected to the outlet of the heat sink via a cooling hose 5. The inlet of the heat sink is required to be located below the heat sink, and the outlet is located above the heat sink. This design allows for the full expulsion of air from the heat sink, preventing air bubbles from forming inside the heat sink and affecting local heat dissipation, which in turn affects the temperature of the electronic components mounted on the heat sink.

[0027] Example 2: Electromagnetic heating. Due to the presence of the induced magnetic field, the machine body and cabinet panels need to maintain a sufficient distance from the induction coil to prevent overheating. When selecting appropriate dimensions, the positions of the cabinet body and cabinet panels must be at least beyond the strong induction distance, and the cabinet panels and cabinet body must not form a closed loop. To ensure that the cabinet panels and cabinet body do not form a loop, the cabinet panels need to be installed in isolation from the machine body. In this example, the cabinet body includes frame columns 10, a top plate 8 installed above the frame columns 10, and side plates 9 installed around the frame columns 10. Insulating pads 13 are provided at the connections between the top plate 8 and the frame columns 10, and between the side plates 9 and the frame columns 10.

[0028] Mounting holes are provided on the frame column 10, and epoxy resin board 11 is fixedly connected to the mounting holes. The side plate 9 is connected to the outside of the frame column 10 by fixing screws 12 and rivet nuts 14, so that the top plate 8 and side plate 9 are insulated from the frame column 10 by the insulating pad layer 13. In this example, epoxy resin board 11 is used as an intermediate isolation fixing piece, and an insulating pad layer is added between the cabinet and the body to achieve insulation isolation between the cabinet and the body, cut off possible metal closed circuits, avoid the formation of unnecessary induced current or eddy current interference, enhance electrical insulation, reduce the risk of electric shock and leakage, and improve the system safety level.

[0029] In summary, this invention, through liquid cooling circulation, can quickly remove the heat generated by the electromagnetic heating controller and electromagnetic coil, preventing temperature buildup. It can effectively control the temperature of the electromagnetic heating controller and electromagnetic heating coil within 50-60℃, thereby reducing the operating temperature of core components. At the same time, it can reduce the wear and tear and maintenance costs of key components, enabling the equipment to operate under continuous high loads for extended periods. This improves the reliability of continuous operation and industrial applicability, enhances the safety assurance capability of the entire machine, and extends the service life of the equipment.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
