Condensing heat exchanger and boiler/water heater including the same

摘要

The present invention relates to a condensing heat exchanger and a boiler/water heater including the same and, more particularly, to a condensing heat exchanger, which can increase a contact area between water and a combustion gas having high temperature and improve efficiency by passing a combustion gas, generated from a combustion chamber, through a plurality of exhaust pipes and which can be fabricated in a small and compact size, and a boiler/water heater including the same.

主权项

1. A condensing heat exchanger, comprising:
a body 100 configured to have a hollow and airtight barrel shape; a combustion chamber 200 provided within the body 100 and configured to have a plurality of through holes 211 for discharging a combustion gas G formed in a top surface of the combustion chamber 200; exhaust pipes 300 configured to have first ends combined with the respective through holes 211 of the combustion chamber 200 and have second ends combined with the body 100; a water inlet port 110 provided on a first side of the body 100 and configured to have water W introduced through the water inlet port 110; a water outlet port 120 provided on a second side of the body 100 and configured to discharge the water W heated within the body 100; wherein the plurality of through holes 211 is formed in the top surface of the combustion chamber 200, the exhaust pipes 300 is formed in a ∩-shaped form, and ends of the exhaust pipes 300 on both sides thereof are connected to the respective through holes 211 of the combustion chamber 200 and an edge part of a lower part of the body 100, and a second fixing member 420 provided at an upper part of the exhaust pipes 300 and configured to position the plurality of exhaust pipes 300 and have a disk shape in order to improve a heat transfer area, a plurality of second through holes 421 formed in a central area of the second fixing member 420 and configured to have the plurality of exhaust pipes 300, connected to the combustion chamber 200, pass through the respective second through holes 421 and a plurality of sawteeth formed in an outer circumferential face of the second fixing member 420 and configured to position the plurality of exhaust pipes 300.
