Abstract
A heat exchanger including a honeycomb structure having partition walls defining fluid cells extending between inflow and outflow end faces, and inner and outer peripheral walls. A first outer cylinder contacts the outer peripheral wall. A first inner cylinder having inflow and outflow ports for the fluid has an outer peripheral surface that contacts the inner peripheral wall. A second inner cylinder having inflow and outflow ports for the fluid is spaced on a radially inner side of the inner peripheral wall. The inflow port of the first inner cylinder is closer to the inflow end face than the outflow end face in an axial direction of the honeycomb structure. The outflow port of the second inner cylinder is closer to the outflow end face than the inflow end face in the axial direction of the honeycomb structure.
