PURPOSE: A heat exchanger is provided to prevent a foreign material from becoming attached to a heat exchange tube since the heat exchange tube is cleaned in short cycle. CONSTITUTION: A heat exchanger comprises a cylindrical unit, a first head unit(20), a second head unit(30), and a plurality of heat exchange tubes(40). The cylindrical unit and the first head unit are divided by a first semispherical diaphragm, the cylindrical unit and the second head unit are divided by a second semispherical diaphragm, a first semispherical finishing member is mounted on the first head unit and a second semispherical member is mounted on the second head unit. A first movable member(50) is arranged on the first head unit, a second movable member(60) is arranged on the second head unit, the first and second movable members are connected by a plurality of first wires(70), which pass through the heat exchange tube. |
