[0025] Optionally, the silicon carbide thermal control terminal includes a heat dissipation module, a temperature monitoring module and a cooling module; the heat dissipation module is used to optimize the heat dissipation path inside the system based on silicon carbide material, thereby improving the heat dissipation efficiency of the system; the temperature monitoring module is used to monitor the temperature of various parts of the system in real time; and the cooling module is used to quickly reduce the system temperature after the welding operation is completed.

[0026] Optionally, the intelligent welding control terminal includes a current regulation module, a voltage control module and a power factor optimization module; the current regulation module is used to dynamically adjust the output current according to welding requirements; the voltage control module is used to adjust the working voltage of the welding machine in real time; the power factor optimization module is used to optimize the phase relationship between current and voltage during the welding process.

[0028] Specifically, when the frequency adjustment submodule is working, the following formula is satisfied: ; Among them, f out Indicates the output current frequency; f in Indicates the input current frequency; V in Indicates input voltage; V out Represents the output voltage; R eq Represents the total equivalent resistance of the current path in the system, obtained through actual measurement; I out Indicates the current output by the output module during welding, that is, the current received by the silicon carbide enhanced welding machine body, which is specifically determined by the welding requirements; L eq Represents the total equivalent inductance of the current path in the system; It represents the rate of change of the output current, that is, the rate of change of the output current over time.

D indicates the length of the heat dissipation path, which is obtained by measurement; C thRepresents the system heat capacity, which is obtained through design testing. In this embodiment, the corresponding heat capacity of the system is 10J / K; α represents the ambient temperature adjustment factor, which usually takes a value between 0 and 0.1. The higher the ambient temperature, the larger the ambient temperature adjustment factor. The specific value is set by the staff based on experience. When in a high-temperature environment, the temperature feedback submodule calculates the target heat dissipation through a formula to accurately and timely complete sufficient heat dissipation, which is conducive to improving the quality and efficiency of heat dissipation. According to the calculated target heat dissipation, the current heat accumulation situation can be understood. When the target heat dissipation is high, the heat dissipation capacity can be adjusted in time, or the heat dissipation capacity and heat dissipation efficiency of the system itself can be improved before the subsequent administrator encounters this situation again, so as to shorten the heat dissipation time; conversely, if the target heat dissipation is low, the heat dissipation power can be reduced in time, or the heat dissipation power of the system itself can be reduced before the subsequent administrator encounters this situation again, so as to save energy.
