PURPOSE: A heat exchanger for a condensing boiler is provided to improve energy efficiency by minimizing radiant heat in which is lost when combustion gas flows in a gap between a vertical heat exchanging plate assemblies. CONSTITUTION: A heat exchanger(1) for a condensing boiler comprises a heat exchanging plate assembly(12) and a plurality of heat exchanging units(15-18). The heat exchanging unit is connected to serially array each flow path of a pair of heat exchanging plate assemblies. The heat exchanging units are installed to be separated from each other for passing combustion gas and forms a gap. |
