| 摘要 |
The present invention relates to a heat exchanger comprising: a mixture inflow unit into which a mixture of air and fuel is introduced; a burner for combusting the mixture introduced through the mixture inflow unit; a heat exchange unit that is disposed around the burner such that heat is exchanged between combustion gas caused by the combustion of the burner and a heating medium, and is constituted with a plurality of unit plates stacked on each other; and a combustion gas discharge unit for discharging the combustion gas having passed through the heat exchange unit, wherein a heating medium passage, a combustion gas passage, and a combustion gas discharge passage that connects the combustion gas passage and the combustion gas discharge unit are formed in the interior of the plurality of stacked unit plates constituting the heat exchange unit, the heating medium passage and the combustion gas passage being alternately formed to be separated from and adjacent to each other in an up-and-down direction. |
