ABSTRACT:
In a heat exchanger including a plurality of tubes1through which a first fluid passes, a housing2in which the tubes1are installed, and sealing members for sealing a second fluid that flows over surfaces of the tubes1, the housing2includes an inlet4for introducing the second fluid therein and a first outlet5and second outlets6for discharging the second fluid, and the sealing members include a first sealing member3apositioned on one of end sides of the tubes1, a second sealing member3bpositioned on the other end side of the tubes1, and a third sealing member3cpositioned between the first and second sealing members3aand3b. The third sealing member3cis provided so that a gap7is provided between the first sealing member3aand the third sealing member3cwhile another gap7is provided between the second sealing member3band the third sealing member3c, and that a flow path for the second fluid is formed therein. The second outlets6are provided so as to be connected to the gaps7.
