Disclosed is a coolant heating device for a vehicle which can secure safety from a fire or explosion caused by overheating without a separate safety device such as a fuse. The coolant heating device for a vehicle comprises: a coolant chamber having a container-type structure of which an upper portion is blocked and of which a lower portion is opened and having a water inlet pipe and a water outlet pipe communicating with the inside on one side thereof and the other side thereof on the opposite side; and a heater assembly installed in the coolant chamber, and electrically connected to a control element in a housing coupled on a lower portion of the coolant chamber. The heater assembly consists of a plurality of thermistor-type unit heaters. The unit heaters are thin and flat and are formed in a long stick shape in the height direction of the coolant chamber. The unit heaters are arranged in a matrix shape to form a plurality of heater rows and heater columns perpendicular to the heater rows. The heater rows are formed such that the thin surfaces of the unit heaters in the thickness direction are separated from each other and face each other. The heater columns are formed such that the flat surfaces of the unit heaters in the width direction are separated from each other and face each other. The surfaces of the unit heaters in the width direction match the longitudinal direction of the water inlet pipe and the water outlet pipe or are arranged in parallel with the longitudinal direction of the water inlet pipe and the water outlet pipe.

    차량용 냉각수 가열장치가 개시된다. 본 발명에 따른 차량용 냉각수 가열장치는, 상부가 막혀 있고 하부는 개방된 통형 구조이며 일측과 반대편 타측에 내부와 통하는 입수관과 출수관이 구비된 냉각수 챔버와, 냉각수 챔버 내부에 설치되며, 냉각수 챔버의 하부에서 결합되는 하우징 내 제어요소와 전기적으로 연결되는 히터 조립체를 포함하며, 히터 조립체는 다수의 서미스터형 단위 발열체들로 구성되고, 단위 발열체 각각은 얇고 평평하며 냉각수 챔버의 높이 방향으로 긴 막대 모양으로 형성되고, 단위 발열체끼리는 복수의 발열체 행 및 상기 발열체 행과 직교하는 발열체 열을 구성하도록 행렬(Matrix) 형상으로 배열되고, 발열체 행은 인접하는 단위 발열체의 두께 방향 얇은 면이 간격을 두고 서로 마주하도록 형성되며, 발열체 열은 인접하는 단위 발열체의 폭 방향 평평한 면이 간격을 두고 서로 마주하도록 형성되되, 단위 발열체의 폭 방향 평평한 면이 상기 입수관 및 출수관의 길이 방향과 일치하거나 평행하게 배치된 것을 요지로 한다.
