Abstract: 본 발명은 수분을 함유하는 고온부의 가스로부터 수열하여 액화가스 기화기에 있어서 극저온인 액화가스의 입구측을 열교환기의 고온측과 열교환되도록 전열관의 유동패턴을 변경하여 고온가스가 흐르는 통로 내에 가스 중의 수증기가 결빙되지 않도록 전열관을 특별하게 구성한 액화가스 기화용 열교환기에 관한 것이다.
본 발명의 주요구성은 수분함유 열매가스가 지나는 열매가스입구부와 열매가스출구부 사이에 형성되는 통로와, 상기 통로에 열매가스의 유동방향에 대해 수직하게 배치되고 입구측이 상기 열매가스입구부에 인접한 상기 통로의 상부에 형성되고, 상기 출구측은 상기 통로의 중간부에 형성되는 전열관을 구비하되, 상기 전열관은 통로의 상부에 형성된 입구측에서 통로의 하부를 경유한 후 중간부에 형성된 출구측으로 연결되고, 상기 전열관의 상부는 열매가스의 흐름방향과 동일한 방향으로 이동되는 병행류형식의 열교환이 이루어지고, 상기 전열관의 하부는 열매가스의 흐름방향과 반대방향으로 이동되면서 대향류형식의 열교환이 이루어지며, 상기 열매가스입구부에 인접한 상부의 병행류 전열관은 액화가스에 의한 수분결빙이 발생하지 않도록 전열면적 큰 것을 특징으로 한다.
