PROBLEM TO BE SOLVED: To provide a heat exchanger considering defects of a present technique, especially a heat exchanger capable of reducing weight, saving space, and reducing production cost.SOLUTION: A heat exchanger comprises: a cold conduit 2 or 3; a hot conduit; and a heat exchanging element 1 arranged between the cold conduits 2 or 3 and the hot conduit. The heat exchanger further comprises at least one other conduit 3 or 2 arranged next to the cold conduit 2 or 3 or the hot conduit on the same surface of the heat exchanging element 1 as the cold conduit or the hot conduit. The other conduits are separated from the cold conduit or the hot conduit by a separator 5 arranged at a location by a certain distance from the other conduits, respectively, and forming a cavity 53 between two separation elements 51, 52. The separator restricts a fluid flow into the cavity 53 or in the cavity 53 so as to restrict heat exchange between the other conduit 3 or 2 on the same surface as the heat exchanging element 1 and the cold conduit or the hot conduit. |
