The present invention relates to a PTC heater. More specifically, the present invention relates to a PTC heater wherein a plurality of PTC elements are aligned spacing apart in a single layer and are embedded in a heat load so as to form rows and columns and the PTC elements are arranged to have a staggered alignment at a center line in a height direction with PTC elements embedded in an adjacent heat load so as to minimize a duplicate area of PTC elements and accordingly, a noise generated by a PWM control is lowered.

    본 발명은 PTC 히터에 관한 것으로, 더욱 상세하게 열 및 행을 이루도록 서로 이격되어 단일층으로 배열되는 다수개의 PTC 소자가 내장되는 히트로드에 있어서, PTC 소자가 서로 중첩되는 영역이 최소화되도록 인접한 상기 히트로드에 내장된 PTC 소자의 높이방향으로 중심선이 서로 어긋나게 배치됨으로써, PWM 제어에 의해 발생되는 소음이 저감될 수 있는 PTC 히터에 관한 것이다.
