AI Technical Summary

Problems solved by technology

Among the various heating forms mentioned above, the direct eddy current heating type has higher thermal efficiency and simpler structure, but they have structural problems that cause hot gas to concentrate and accumulate, resulting in overheating of components such as resonant coils and integrated controllers. Strong cooling and heat dissipation measures must be adopted, and the temperature of the hot water should not be too high, otherwise it will be more difficult to dissipate heat, and it will be more likely to be damaged and unable to work normally

Especially with the inverted U-shaped tube type, the closer it is to the hot water outlet section, the higher the temperature and the accumulation of hot gas, the easier it is to burn out the resonant coil and the integrated controller

However, the heating temperature is low, which will not meet the temperature requirements, especially in winter or cold areas, and must use high-power fans to dissipate heat and cool down, which will reduce the electromagnetic heating efficiency and increase energy consumption.

Due to the inability to solve problems such as overheating according to the requirements of use, practical applications cannot be realized; similarly, structural forms including coil flat sandwich type, double-sided sandwich groove type, etc., cannot completely solve the above problems

They all still have the problems of low heating speed, large power requirement and high energy consumption because they do not make full use of the magnetic efficiency of the magnetic lines of force in all directions of the electromagnetic field to improve the utilization efficiency of magnetic energy.

Because of the above-mentioned problems in the prior art, there is no electromagnetic heating type or electromagnetic resistance composite heating water heater on sale and application in the market and practical application fields so far, and there is no electromagnetic water boiler that can be used as a higher temperature requirement. , and the above-mentioned water heaters used in industrial, commercial and agricultural fields
