Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2017/014497
Kind Code:
A1
Abstract:
The present invention relates to a heat exchanger enabling the reduction of the number of components constituting the heat exchanger, the simplification of the coupling structure thereof, and also, the decrease of combustion gas flow resistance and the minimization of noise and vibration generation, the heat exchanger being provided with a heat exchange unit having heating medium flow channels through which a heating medium flows and combustion gas flow channels through which combustion gas combusted in the burner flows to be alternately formed and adjacent to each other in spaces between a plurality of plates, wherein the heat exchange unit comprises: a sensible heat unit which surrounds the outer side of a combustion chamber, is formed of one side area of the plates, and heats the heating medium by using sensible heat of combustion gas generated by the combustion of the burner; and a latent heat unit which is formed of the other side area of the plates, and heats the heating medium by using latent heat of water vapor included in combustion gas that has finished undergoing heat exchange in the sensible heat unit, wherein bent flange units are formed on the edges of the plurality of plates, and in a state where the flange units of neighboring plates overlap, certain areas among the edges of the plurality of plates have formed thereon combustion gas pass-through units having combustion gas flowing through the combustion gas flow channels pass therethrough.
