Uptrend Combustion Condensing Type Heat Exchanger of Gas Boiler

摘要

PURPOSE: An upward combustion condensing type heat exchanger of gas boiler is provided to maximize absorption of condensed latent heat contained in exhaust gas. CONSTITUTION: A latent heat part(300) comprises a first lower guide(56) and a second lower guide(58) symmetrically formed to have one side connected to lower ends of a first latent heat part cover(64) and a second latent heat part cover(65) and the other side inclined up toward a center of the latent heat part so as to guide exhaust gas and to collect condensed water; an upper guide(63) placed on upper side of the first lower guide and the second lower guide and having both ends bending to face each other and to be separated from the first lower guide and the second lower guide so as to guide exhaust gas together with the first lower guide and the second lower guide; a first latent heat part heat exchanger(61) and a second latent heat part heat exchanger(62) placed between the upper guide and the first lower guide and the second lower guide and having heat exchange pipes arranged therein to absorb heat of exhaust gas; and a first condensed water outlet(57) and a second condensed water outlet(59) formed to guide condensed water collected in the first lower guide and the second lower guide to a condensed water outlet(67).
