Abstract

The invention discloses a heating device eliminating induced electricity. The device comprises an aluminum radiating member (201) in a hollow structure; the aluminum radiating member (201) is provided with a radiating cavity (202) inside; the radiating cavity (202) is provided with a PTC heater (203) inside. The PTC heater (203) comprises a ceramic heating sheet (4), a first electrode plate (3), a second electrode plate (2) and an insulating layer (1); the electrode plates connected to the zero line serve as shielding layers directly, the number of heat insulation layers is reduced, the heat conduction performance is improved, and the manufacture process is simple.

Description

technical field [0001] The invention belongs to the technical field of PTC heaters, in particular to a PTC heating device for eliminating induced electricity. Background technique [0002] At this stage, all PTC heaters will generate induction electricity. The existing technology 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 to the neutral line, and there is an insulating layer between the shielding layer and the aluminum heat dissipation surface, so that the potential of the shielding layer 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 inventors 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...
