The electric heating pipe is welded to the aluminum plate, and the electric heating plate has a certain effect, and the thermal conductivity function will be damaged.
At present, there are two structural forms, one is to cast the electric heating tube into the aluminum cast electric heating plate during manufacturing, the rice cooker, electric pressure cooker, etc. are basically this structure, the other is to open a groove in advance on the electric heating plate, and then embed the electric heating tube and fix the piping, which is more common in electric teapots and other structures.
In general, the electric heating tube is difficult to break, you can use a multimeter to detect the leads at both ends of the electric heating tube to see if there is resistance, if there is no resistance, the electric heating tube is broken, the general electric kettle is broken usually the temperature control is broken or the temperature control fuse is blown out, these can be detected by the multimeter measuring resistance.
