[0025] The present application will be further described below in conjunction with the drawings.

[0026] As Figure 1As shown, in this embodiment, the high-pressure pipe 4 is used to contain the liquid to be heated. The electromagnetic heater 2, constructed of coiled copper tubing, is located outside the high-pressure pipe 4 and is used to electromagnetically heat the liquid inside the high-pressure pipe 4. Utilizing the rapid heating characteristic of electromagnetic heating, the liquid, which is initially in a static state, is quickly and significantly heated, achieving rapid generation and accumulation of heat energy. The low-pressure pipe 8 is connected in series with the high-pressure pipe 4 to form a closed liquid flow loop. After being heated in the high-pressure pipe 4, the liquid flows into the low-pressure pipe 8 through a pressure difference provided by a liquid pump 5, which is connected in series in the liquid flow loop formed by the high-pressure pipe 4 and the low-pressure pipe 8.

[0027] In this embodiment, the electronic control system is used to monitor the temperature and pressure within the high-pressure pipe 4 and the low-pressure pipe 8, and adjust the power of the electromagnetic heater 2 and control the start and stop of the liquid pump 5 based on the monitoring data, thereby achieving regulation and control of temperature and heating rate, and limiting the pressure in the liquid flow circuit within a safe range. Figure 1 As shown, the electrical control system includes a frequency converter 1, a temperature sensor 7, and a pressure sensor 6. The temperature sensor 7 and the pressure sensor 6 are both installed on the liquid flow circuit. The temperature sensor 7, the pressure sensor 6, the electromagnetic heater 2, and the liquid pump 5 are all electrically connected to the frequency converter 1.

[0028] like Figure 1 As shown in this embodiment, an insulating sleeve 3 is provided between the high-pressure pipe 4 and the electromagnetic heater 2. The insulating sleeve 3 isolates the electromagnetic heater 2 from the high-pressure pipe 4 to ensure insulation, thereby separating water and electricity.

[0029] like Figure 1 As shown, there are two low-pressure pipes 8. When there are multiple low-pressure pipes 8, each low-pressure pipe 8 is connected in series or in parallel to form a group and then connected in series with the high-pressure pipe 4.

[0030] like Figure 2 and 3 As shown, in this embodiment, an axial baffle 9 is provided inside the high-pressure pipe 4, which divides the high-pressure pipe 4 into at least two flow channels 10. The arrangement of multiple flow channels 10 can significantly reduce the convection of hot and cold liquids when flowing in the high-pressure pipe 4, allowing the heated hot water in the high-pressure pipe 4 to be fully discharged, thereby improving heating efficiency.

[0031] like Figure 2 and 3As shown, in the embodiment, the liquid flow circuit is connected in series with an electrically controlled valve 11, which is electrically connected with the variable frequency controller 1. The electrically controlled valve 11 can cut off the liquid flow circuit in an emergency to avoid the accident from getting worse, and can also cut off the liquid flow circuit when the electromagnetic heater 2 is heating, so that the electrically controlled valve 11 is turned on after the temperature of the liquid in the high-pressure pipe 4 is greatly increased, and the high-temperature liquid storing a large amount of heat is circulated to the low-pressure pipe 8, so that the temperature increasing speed of the low-pressure pipe 8 is faster.

[0032] Working principle:

[0033] When the liquid heating device is used, first, the liquid to be heated is injected into the high-pressure pipe 4. After the electromagnetic heater 2 is started, the liquid is rapidly heated under the action of the high-frequency electromagnetic field. When the temperature of the liquid reaches the preset value, the control system automatically adjusts the pressure of the high-pressure pipe 4 by starting the liquid pump 5, so that the heated liquid rapidly flows into the low-pressure pipe 8. Due to the pressure difference between the high and low pressures, the liquid forms rapid flow in the low-pressure pipe 8, further improves the heat exchange efficiency, and realizes rapid heating.
