The present invention relates to a cooling water heater for a fuel cell vehicle. A flat baffle (40) having penetration holes (41) is installed between a cooling water inlet (12) and a heating body (30). Cooling water is spread to all the upper and lower parts of the cooling water housing (10) by the baffle (40) and is uniformly supplied to the heating body (30). Thereby, the local heating of the heating body (30) can be prevented. The heat exchange performance of the cooling water heater can be improved.
본 발명은 연료전지차량의 냉각수 히터에 관한 것으로, 냉각수 입구(12)와 발열체(30) 사이에 다수의 통공(41)이 형성된 판형의 배플(40)이 설치된다. 배플(40)에 의해 냉각수가 냉각수하우징(10)의 상하 전체 범위로 확산되어 발열체(30)전체에 균일하게 공급됨으로써 발열체(30)의 국부가열현상이 해소되고, 냉각수 히터의 열교환 성능이 향상된다.
