<P>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of properly preventing such a trouble as drain which is generated following heat recovery and exhausted to the outside of a case through an exhaust opening and properly reduces the size in the vertical direction. <P>SOLUTION: The heat exchanger HE includes a case 7 which contains an air supply opening 71 and an exhaust opening 72 for the heating gas, and a heat propagation pipe 4 which is stored in the case 7 and can recover heat from the heating gas that has entered the case 7 from the air supply opening 71. A partitioning wall 8 is provided in the case 7. In the case 7, a heat exchange region 76 in which the heat propagation pipe 4 is stored and an exhaust introducing chamber 77 of which the exhaust opening 72 is provided at an upper wall 70b are so formed by partitioning that they are arrayed in the horizontal direction. Between the heat exchange region 76 and the exhaust introducing chamber 77, a communication opening 80 is formed which introduces the heating gas that has completed heat recovery to the exhaust introducing chamber 77 from the heat exchange region 76. <P>COPYRIGHT: (C)2012,JPO&INPIT |
