The present invention relates to a cooling water heater mounted for cold start and load consumption of a stack in a fuel cell vehicle. The present invention provides a cooling water heater for a fuel cell vehicle, which can promote uniformization of the whole heater temperature distribution as well as effectively lowering a temperature of a heater central portion, by realizing a new cooling water flow guide to perform a heater heat transmission plate role as well as distributing a flow rate by lengthily extending the flow guide to the heater central portion. Moreover, a material of the cooling water flow guide arranged in an entrance of the cooling water heater is applied with a metal material having high coefficient thermal conductivity.

    본 발명은 연료전지 차량에서 스택의 냉시동 및 부하소모를 위해 탑재되는 냉각수 히터에 관한 것이다. 본 발명은 냉각수 히터의 입구에 배치되는 냉각수 유동 가이드의 재질을 열전도 계수가 높은 금속재질로 적용함과 더불어 유동 가이드를 히터 중앙 부분까지 길게 연장시켜서 유량 분배 뿐만 아니라 가이드가 히터 열전달 플레이트 역할도 동시에 수행할 수 있도록 한 새로운 냉각수 유동 가이드를 구현함으로써, 히터 중앙부의 온도를 효율적으로 낮출 수 있는 등 전체적인 히터 온도 분포의 균일화를 도모할 수 있는 연료전지 차량의 냉각수 히터를 제공한다.
