<p>PURPOSE: A heat exchanger is provided to improve a heat exchange function by increasing the surface of a heat exchanging wall. CONSTITUTION: A heat exchanger comprises a first heat exchanging tube, a second heat exchanging tube(200), and a third heat exchanging tube(300). The first heat exchanging tube is pipe shape and has first inlet and outlet for first fluid inflow and outflow. The second heat exchanging tube has second inlet and output for second fluid inflow and outflow. The third heat exchanging tube has third second inlet and output for third fluid inflow and outflow.</p> |
