PURPOSE: A heat exchanger is provided to improve thermal efficiency by increasing contact time and area between flame and pipe by discharging the flame generated from a burner by an inducing panel. CONSTITUTION: A heat exchanger includes a pipe(10), a fin(20), a conduction panel(30) and heats water passing through the pipe by using the burner. The fin is formed around the pipe. The induction panel has a long planar shape in the longitudinal direction of the pipe. The induction panel is separated from the outer side of the pipe around the pipe and induces the flame generated from the burner. The fin is made of metal plates and a plurality of metal fins are combined with the outer side of the pipe to be mutually separated. A bent piece(31) is formed on one side of the fin. |
