협소한 공간에 설치 가능하고, 다수의 PTC 발열체를 설치 가능하여 높은 발열용량을 가질 수 있으며, 냉각수가 원활히 유동될 수 있는 PTC 히터를 개시한다. PTC 히터는 냉각수가 한 방향으로 흐르도록 구성되는 히팅 챔버 및 히팅 챔버에 결합되고, 열을 발산하여 히팅 챔버의 내부에 흐르는 냉각수를 가열하도록 구성되는 PTC 발열체를 포함하고, 히팅 챔버는, 냉각수가 유입되는 입구와 연통되는 제1 버퍼 및 냉각수가 배출되는 출구와 연통되는 제2 버퍼를 가지는 제1 탱크, 제1 탱크로부터 이격 배치되고, 내부로 유입된 냉각수의 이동방향을 전환하도록 구성되는 제2 탱크, 제1 탱크와 제2 탱크를 연결하고, 제1 버퍼를 통해 내부로 유입된 냉각수를 제2 탱크로 안내하는 제1 가이드 튜브 및 제1 탱크와 제2 탱크를 연결하고, 제2 탱크를 통해 내부로 유입된 냉각수를 제2 버퍼로 안내하는 제2 가이드 튜브를 포함한다.

    Disclosed is a PTC heater that can be installed in a small space, wherein a plurality of PTC heating elements can be installed so that the PTC heater has a high heating capacity, and a coolant can flow easily through the PTC heater. The PTC heater comprises: a heating chamber configured such that a coolant flows in one direction; and PTC heating elements that are coupled to the heating chamber and configured to radiate heat and thereby heat the coolant flowing inside the heating chamber. The heating chamber includes: a first tank that has a first buffer, in communication with an inlet through which a coolant flows in, and a second buffer, in communication with an outlet through which the coolant flows out; a second tank that is spaced apart from the first tank and configured to switch the flow direction of the coolant that flows in; a first guide tube that connects the first tank and the second tank and guides, to the second tank, the coolant that flows in via the first buffer; and a second guide tube that connects the first tank and the second tank and guides, to the second buffer, the coolant that flows in via the second tank.
