What are the four kinds of faults that are easy to occur in electric vehicle heaters?

4. Cracking of electric heating element: Many electric vehicle heater plants have invested a lot of experience and research on the cracking of tube shell heat exchanger. However, there are few papers on the cracking of electric heater element. The reason is that the electric heating element is full of solid magnesium oxide powder, which can crack. In high voltage situations, the magnesium oxide powder can also be knocked out of the wiring chamber, causing electrical leakage.
