HEAT EXCHANGER
First Claim
1. A heat exchanger comprising:
- a heat exchange unit (200) in which heating medium flow channels through which a heating medium flows in a space between a plurality of plates and combustion gas flow channels through which a combustion gas combusted in a burner (100) flows are alternately formed to be adjacent to each other,wherein the heat exchange unit (200) is configured with a sensible heat unit (200A) configured to surround an outer side of a combustion chamber (C), configured with an area at one side of a plate, and configured to heat the heating medium using sensible heat of the combustion gas generated by the combustion in the burner (100); and
a latent heat unit (200B) configured with an area at the other side of the plate and configured to heat the heating medium using latent heat of water vapor contained in the combustion gas which undergoes heat exchange in the sensible heat unit (200A), anda water housing cooling unit (B) formed at a rear side of the sensible heat unit (200A) and configured to provide a connection flow channel of a heating medium which passes through a heating medium flow channel of the latent heat unit (200B) to direct the heating medium to flow into a heating medium flow channel of the sensible heat unit (200A), and heat-insulate the combustion chamber (C).

Abstract
The present invention relates to a heat exchanger having a simplified assembly structure as well as a simplified structure for heat-insulating a combustion chamber, 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 the rear of the sensible heat unit has provided thereon connection flow channels of the heating medium so that the heating medium that passed through the heating medium flow channels of the latent heat unit can flow to the heating medium flow channels of the sensible heat unit, and the rear of the sensible heat unit also has a water housing cooling unit formed thereon for heat-insulating the combustion chamber.
