The method includes: S1, constructing the structure of the steam generator, and obtaining structural parameters; S2, solving the process of electromagnetic induction heating and heat transfer according to the constructed structure and obtained structural parameters, and obtaining the temperature field distribution and internal components of the steam generator surface heat flux density; S3, obtain heating efficiency, frame surface temperature distribution, average temperature of control module area and frequency conversion module area; S4, if all three conditions are satisfied, complete manufacturing; if at least one of the three conditions is not satisfied , adjust the internal structure of the steam generator and return to S2. This method adjusts the internal structure to ensure heating efficiency, reduces energy loss, avoids local high temperature on the surface of the frame that is not good for user experience, makes the control module and frequency conversion module work within the allowable temperature range, and improves operation stability and reliability. and security.

Description

technical field [0001] The invention relates to a steam generator, in particular to a manufacturing method of an electromagnetic induction steam generator and the steam generator. Background technique [0002] At present, most of the industrial low-pressure steam generators on the market use fuel oil heating, coal-fired heating or electric heating tube heating, etc. These traditional heating methods all have problems such as large energy consumption, high operating costs, and environmental pollution. The country actively promotes green, environmentally friendly, high-efficiency and energy-saving forms of new energy, and the increasingly serious problem of smog, these low-efficiency heating methods are gradually being eliminated. Compared with the above-mentioned traditional heating methods, electromagnetic heating steam generators have appeared. Electromagnetic heating steam generators not only solve the problems of low thermal efficiency, high energy consumption, and seriou...

AI Technical Summary

Problems solved by technology

However, existing electromagnetic induction steam generators also have problems such as poor heat dissipation of the steam generator shell, resulting in local high temperature inside, partial metal shell or internal metal structure heating due to electromagnetic induction, and frequency conversion module under high power conditions. Joule heat temperature is too high and the distance between the two tanks is unreasonable, which leads to the decrease of electromagnetic conversion efficiency and other problems, which brings risks to the operation stability and safety of the steam generator, and the energy loss is relatively large
