The present invention relates to a PTC heater having excellent radiation performance. The PTC heater comprises: a housing; a plurality of PTC heating rods placed above and below on one side of the housing at regular intervals and supported by the housing; and a plurality of radiation fins inserted into each of the PTC heating rods while being placed in a lateral longitudinal direction of each of the PTC heating rods. A middle one of three adjacent radiation fins of the radiation fins is placed forward and backward in a linear shape when seen from above, and the other radiation fins on the left and right sides are placed diagonally opposite to each other. Therefore, since an air retention period is extended through a space structure in which air flows from two inlets on the rear side to two small outlets on the front side when the air flows through a space between the three adjacent radiation fins, the PTC heater is capable of increasing efficiency in exchanging heat between the air and the PTC heating rods by increasing time for contact with the air through an arrangement structure of each of the radiation fins.

    본 발명은 하우징; 상기 하우징의 일측에 상하로 일정 간격을 두고 배치되면서 상기 하우징에 의해 지지되는 다수의 피티씨 히팅로드; 및 상기 각 피티씨 히팅로드에 끼워지되, 상기 각 피티씨 히팅로드의 좌우 길이방향을 따라 배치되는 다수의 방열핀;으로 이루어지되, 상기 각 방열핀 중 이웃한 3개의 방열핀에서 중간에 배치된 방열핀은 상부에서 바라보았을 때 전후 일자 형태로 배치되고, 좌측에 배치된 방열핀과 우측에 배치된 방열핀은 서로 마주하는 방향으로 경사진 형태로 배치되어 있어, 이웃한 3개의 방열핀 사이사이 공간으로 공기가 이동될 때에 후방 측 2개의 입구에서 전방 측 2개의 협소한 출구로의 공간 구조를 통해 공기의 체류 시간을 늘릴 수 있도록 구현함으로써, 각 방열핀의 배열 구조를 통해 공기와의 접촉시간을 늘리어 피티씨 히팅로드와 공기 간의 열교환 효율을 높일 수 있도록 한 방열 성능이 우수한 피티씨 히터에 관한 것이다.
