A boiler heat exchanger is provided to obtain constructional convenience of the heat exchanger by simply assembling and manufacturing the heat exchanger, and to lessen the economic pressure of consumers by reducing the overall cost of the heat exchanger. A boiler heat exchanger comprises: a central flue(100); an outer cover(200) having a diameter larger than that of the central flue; a guide plate(300) which is fitted into a bottom part of the outer cover, and on which a bent guide(310) is formed; a lower cover(400) connected to the bottom part of the outer cover under the guide plate; and a heat exchange pipe(500) longitudinally installed on an outer surface of the central flue from a lower part of the central flue to an upper part thereof. |
