Abstract

The invention discloses a PCB composite board for a PTC heater. The PCB composite board comprises a positive plate and a negative plate, wherein the positive plate is provided with a plurality of positive pole jacks, and the negative plate is provided with a plurality of negative pole jacks; the end part of the positive plate is provided with a positive wire welding end, and the end part of the negative plate is provided with a negative wire welding end; the positive wire welding end and the plurality of positive pole jacks are electrically connected through a positive printed circuit on the positive plate; the negative wire welding end and the plurality of negative pole jacks are electrically connected through a negative printed circuit on the negative plate; and the positive plate and the negative plate do not contact with each other. The PCB composite board provided by the invention improves the technical problems of poor heat dissipation performance, low safety, low yield and the like of conventional PCB boards, and has the characteristics of simple structure, good heat dissipation performance, high qualified rate of welding, good safety performance and the like.

Description

technical field [0001] The invention relates to the field of PCB boards, in particular to a PCB composite board for a PTC heater. Background technique [0002] At present, in the field of new energy vehicles, the comfort of winter compartments and the charging and discharging of power batteries require a certain amount of heat. Since electric vehicles currently lack the waste heat of engines of traditional vehicles, electric heating systems must be used for heating; Automobiles require high energy density, long life of batteries and customer-oriented high-power fast charging capabilities. At present, the thermal management solutions of domestic manufacturers continue to upgrade to fast liquid cooling, direct cooling and other solutions. The existing liquid heating PTC assembly Including water chamber, control box, heating aluminum seat, etc.; wherein the heating aluminum seat is also equipped with a heating package assembly and a PCB circuit board, the heating package assemb...
