Problems solved by technology

PTC heating technology has been widely used in home appliance industries such as heaters and air conditioners. The metal electrode is laminated with the aluminum-sprayed electrode of the PTC heating sheet, wrapped with polyimide composite film and placed in an aluminum tube. After the electrodes are led out of the aluminum tube, the PTC heating plate is heated by power-on, and the heat is transferred through the heat sink on the aluminum tube to achieve the purpose of heating; but its contact resistance is large, so the electrode is easy to be ignited and burned, which affects the PTC heater. safety and service life
