Abstract
A heat exchanger unit according to the present disclosure includes a combustion chamber in which a flame caused by a combustion reaction is located, a heat exchanger for a condensing boiler, the heat exchanger being located under the combustion chamber and including heat exchange pipes that receive heat generated by the combustion reaction and heat heating-water flowing through the heat exchange pipes and a main case having the heat exchange pipes accommodated in an interior space thereof, and a combustion chamber heat insulation pipe that is disposed adjacent to the combustion chamber and that receives the heating-water and allows the heating-water to flow therethrough to thermally insulate the combustion chamber.
Claims20
A heat exchanger unit comprising:
- a combustion chamber in which a flame caused by a combustion reaction is located;
- a heat exchanger for a condensing boiler, the heat exchanger being located under the combustion chamber, wherein the heat exchanger includes heat exchange pipes configured to receive heat generated by the combustion reaction and to heat heating-water flowing through the heat exchange pipes and a main case having the heat exchange pipes accommodated in an interior space thereof;
- and
- a combustion chamber heat insulation pipe disposed adjacent to the combustion chamber and configured to receive the heating-water and allow the heating-water to flow therethrough to thermally insulate the combustion chamber.
A method for manufacturing a heat exchanger unit, the method comprising:
- assembling a heat exchanger using a paste for brazing;
- assembling a combustion chamber using a paste for brazing;
- assembling the combustion chamber and a combustion chamber heat insulation pipe;
- applying a paste for brazing to at least one of one surface of the combustion chamber that is to be brought into contact with the heat exchanger or one surface of the heat exchanger that is to be brought into contact with the combustion chamber;
- forming the heat exchanger unit by seating the heat exchanger on the combustion chamber;
- and
- performing brazing by heating the heat exchanger unit.
