PURPOSE: A divided heat exchanger is provided to raise heat exchange efficiency by constructing a reinforced structure against an external pressure. CONSTITUTION: A divided heat exchanger comprises pipe assembly(10), an inner pipe body(20), and an outer pipe body(30). The pipe assembly includes pipes, an upper support plate, and a lower support plate. The pipes are installed in parallel and have a bellows pipe shape. The upper support plate is coupled to the upper end of the pipe. The lower support plate is coupled to the lower end of the pipe. The inner pipe body surrounds the pipe assembly to be closely adhered to the edge of the upper support plate and forms a combustion chamber in the lower side of the pipe assembly by being formed longer than the pipe assembly. The inner pipe body includes the penetration hole formed right on the lower support plate and a second entering/leaving port. The outer pipe body surrounds the inner pipe body in the state separated from the inner pipe body and comprises a first entering/leaving port. The upper end of the outer pipe body is coupled to the inner pipe body at the upper side of the penetration hole and the lower end of the outer pipe body is coupled to the lower end of the inner pipe body. |
