Abstract
A heat exchanger for lowering the temperature of exhaust gas emitted from an internal combustion engine has a container body adapted to store water which serves a heat exchanging medium therein, an exhaust gas discharging chamber adapted to discharge the exhaust gas from the engine into the water in the form of gas-bubbles, a partition member mounted above the surface of water stored within said container body so as to catch splash of water, water-bubbles and vapor generated by evaporation of water and drop them within the container body; an exhaust gas inlet formed in the peripheral side surface of the container body and connected to exhaust pipe for the engine; an exhaust gas introduction passage for connecting the exhaust gas inlet and the exhaust gas discharging chamber; an exhaust gas exit chamber defined in the uppermost part of the inside of the container body; and an exhaust gas outlet pipe connected to the top of said container body to discharge the exhaust gas within the exhaust gas discharge chamber outside the container body.
