PURPOSE: A heat exchanger is provided to maximize thermal efficiency by utilizing latent heat by circulating hot combustion air in a water inflow unit. CONSTITUTION: A heat exchanger comprises a burner(10), a heat exchanger(20), a lid plate(30), a gas exhausting tube(40), and a water supply and exhausting part(50). The burner produces the exhaust gas of the high temperature. The heat exchanger is comprised of a plurality of heat exchanging plates(22). The heat exchanging plates are vertically spaced at a predetermined gap and stacked. The heat exchanging plates exchange the heat with adjacent upper and lower layers for exhaust gas is exhausted. The lid plate covers the top of the heat exchanging plate. The gas exhausting tube discharges the exhaust gas to outside. The water supply and exhausting part supplies the water to the heat exchanger and discharges heat-exchanged water. |
