Two metal sheets are adhered to both sides of the PTC heating element, and two wires are led out as energized electrodes. It does not require an additional temperature control device and has the characteristics of sustainable heating, safety and reliability, stable power, and a wide range of operating voltages. The existing PTC heating devices mainly have two forms, one is the surface-charged type, and the other is the surface-uncharged type; for the surface-charged PTC heating device, the heat dissipation strip is directly adhered to the PTC heating element with thermal conductive glue, and the positive and negative terminal electrodes are directly led out from the heat dissipation strip.

[0003] When installing and using the PTC heater, a plastic seat for the PTC heater is required to facilitate the installation and fixation of the PTC heater. Currently, for the existing plastic seat for the PTC heater, it is locked at both ends of the PTC heating element by means of screwing; one hand holds the electric screwdriver manually, and the other hand fixes and presses the plastic seat to be locked to complete the screwing. However, this manual fixing method will cause the plastic seat to shake with the PTC heating element during the screwing process, resulting in inaccurate screwing angles during the installation process; and it is not convenient for installation, time-consuming and laborious, increasing the labor of the workers and reducing the work efficiency of the workers.
