Abstract:
1. A heat exchanger comprising: a stacked core including a stacked plurality of unit members in each of which a first inlet passage formation portion, a first outlet passage formation portion, a second inlet passage formation portion, and a second outlet passage formation portion are independent of each other and extend from a heat-exchange passage formation portion along a plane, wherein the stacked core includes a plurality of heat-exchange portions in each of which a first heat-exchange passage and a second heat-exchange passage are adjacent to each other via the heat-exchange passage formation portion, the first heat-exchange passage being configured to flow a first heat-exchange medium through the first heat-exchange passage from the first inlet passage formation portion to the first outlet passage formation portion, and the second heat-exchange passage being configured to flow a second heat-exchange medium through the second heat-exchange passage from the second inlet passage formation portion to the second outlet passage formation portion; a case including a shape in accordance with an outer shape of the stacked core, and which houses the stacked core such that the first heat-exchange medium and the second heat-exchange medium flow into and flow out of the stacked core; and a layer formation seal provided between an inner surface of the case and an outer surface of the stacked core, and which forms a heat-insulation layer between the case and the stacked core, wherein the heat-insulation layer is a closed space separated from an outside, and an entirety of the stacked core that is inside the closed space does not conductively contact the case; wherein the layer formation seal seals an area between the case and an entire periphery of a stacked portion of the first inlet passage formation portions in the stacked core, along a plane crossing a direction in which the first heat-exchange medium flows, and an area between the case and an entire periphery of a stacked portion of the first outlet passage formation portions in the stacked core, along the plane crossing the direction in which the first heat-exchange medium flows, and the layer formation seal seals an area between the case and an entire periphery of a stacked portion of the second inlet passage formation portions in the stacked core, along a plane crossing a direction in which the second heat-exchange medium flows, and an area between the case and an entire periphery of a stacked portion of the second outlet passage formation portions in the stacked core, along the plane crossing the direction in which the second heat-exchange medium flows.
