Title:
HEAT EXCHANGER UNIT AND CONDENSING BOILER USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/235780
Kind Code:
A1
Abstract:
A heat exchanger unit according to the present invention comprises: a sensible heat exchanger including a sensible heat exchange pipe disposed in a sensible heat exchange area for heating water used for heating by receiving sensible heat generated by a combustion reaction, wherein the sensible heat exchange pipe receives the water used for heating and flows same through the interior, and a sensible heat fin disposed in the sensible heat exchange area, wherein the sensible heat fin is formed in a plate shape across the sensible heat exchange pipe and penetrated by the sensible heat exchange pipe; and a latent heat exchanger positioned downstream from the sensible heat exchange area on the basis of a reference direction, which is a flow direction of combustion gas generated during the combustion reaction, the latent heat exchanger including a latent heat exchange pipe disposed in a latent heat exchange area for heating the water used for heating by receiving latent heat generated during a phase change of the combustion gas, wherein the latent heat exchange pipe receives the water used for heating and flows same through the interior, and a latent heat fin disposed in the latent heat exchange area, wherein the latent heat fin is formed in a plate shape across the latent heat exchange pipe and penetrated by the latent heat exchange pipe.
