The present invention relates to a cooling water heating type heater and, more specifically, relates to a cooling water heating type heater and a manufacturing method thereof capable of effectively heating cooling water using a first heating pipe with a first heating part and a second heating pipe with a second heating part; simplifying components and an assembly process, and increasing productivity by welding protection pipes to protect the heating parts with covers; and obtaining durability and increasing stability even through being in direct contact with the cooling water. The manufacturing method of the cooling water heating type heater comprises: (S10) a first heating pipe manufacturing step of manufacturing a first heating pipe (200) having a first pipe (201), and a first heating part (210) formed on an outer surface of the first pipe to be heated; (S20) a second heating pipe manufacturing step of manufacturing a second heating pipe (300) having a second pipe (301) formed with a larger diameter of the first pipe (201) to contain a predetermined area of the first heating pipe (200), and a second heating part (310) formed on the outer surface of the second pipe (301) to be heated; and (S30) an assembly step of assembling a case (100) formed with a larger area than the second pipe (301) to contain a predetermined area of the second heating pipe (300), the first heating pipe (200), and the second heating pipe (300).
본 발명은 냉각수 가열식 히터에 관한 것으로서, 더욱 상세하게, 본 발명은 제1발열부가 형성된 제1발열파이프와 제2발열부가 형성된 제2발열파이프를 이용하여 냉각수를 효과적으로 가열할 수 있으며, 발열부를 보호하는 보호관 및 커버가 용접됨으로써 구성품 및 조립 공정을 간소화할 수 있고, 생산성을 보다 높일 수 있으며, 냉각수와 직접 접촉되더라도 내구성을 확보할 수 있고, 안정성을 높일 수 있는 냉각수 가열식 히터 및 그 제조 방법에 관한 것이다.
