Description

Technical field

[0001] The invention belongs to the technical field of PTC heaters, and particularly relates to a PTC heater device for eliminating induced electricity. Background technique

[0002] At this stage, all PTC heaters can generate induction electricity, and the prior art mainly eliminates induction electricity by adding a metal shielding layer. The method is to surround a metal shielding layer outside the heating element, the shielding layer is connected with the neutral line, and the shielding layer is separated from the aluminum heat dissipation surface by an insulating layer, so that the shielding layer potential is approximately zero, thereby eliminating the induction on the surface of the aluminum heat sink Electricity.

[0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: However, the prior art has poor thermal conductivity, high failure rate, and low manufacturability when fabricati...
