| 摘要 |
The present invention relates to a condensing boiler including a sensible heat exchange part arranged in a ring shape around a burner and a latent heat exchange part adjacent to the sensible heat exchange part to exchange heat while high-temperature gas burned in the burner passes and moves between pipes of the sensible heat exchange part and exchange heat while the combustion gas passes between pipes of the latent heat exchange part. The condensing boiler is disposed between the latent heat exchange part and the sensible heat exchange part to block the combustion gas not to be immediately discharged. An uneven part (102) is formed at the outer side of the baffle. A relatively protruding part (108) is fixed to a pipe (111) of a latent heat exchange part (110), and the opposite surface is separated by forming a gap (122) from a pipe (121) of an adjacent sensible heat exchange part (120) to make combustion gas move and conduct heat exchange. A concave part (109) adjacent to the protruding part (108) attached to the latent heat exchange part at the uneven part is attached to the pipe (121) of the sensible heat exchange part, and the opposite surface has a gap (112) between the pipe (111) of the latent heat exchange part to conduct heat exchange by the discharged combustion gas. The present invention improves heat exchange efficiency by making the combustion gas move between the pipe of the sensible heat exchange part and the pipe of the latent heat exchange part which are adjacent to each other at both sides of the baffle by forming the uneven part at the outer side of the baffle. |
