Novel high-voltage weight-reducing PTC (Positive Temperature Coefficient) heater

The utility model discloses a novel high-voltage weight-reducing PTC heater which comprises a plurality of aluminum strips, the aluminum strips are cuboid-shaped, an aluminum pipe is arranged between the side walls, close to each other, of every two adjacent aluminum strips, the inner wall of each aluminum pipe is connected with a PTC chip in a sliding mode, the upper end and the lower end, away from the corresponding aluminum pipe, of each PTC chip are fixedly connected with copper electrode plates, and the copper electrode plates are fixedly connected with the aluminum pipes. The PTC chip and the side wall of the copper electrode plate are wrapped with insulation paper. According to the utility model, heat on the PTC chip can be dissipated through the insulation paper and the aluminum tube, so that the use of the ceramic insulation substrate is reduced, and meanwhile, as the ceramic insulation substrate is made of a material with a relatively low heat conductivity coefficient, the heat dissipation of the PT
