摘要： 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.

摘要： A heat exchanger element includes at least two honeycomb structures arranged serially and each including a cell structural portion having cells separated and formed by partition walls containing SiC and functioning as passages which extend from one end face to the other end face and which a first fluid passes through, and an outer peripheral wall disposed on the outer periphery of the cell structural portion. The first fluid passes through the cells of the honeycomb structures without leaking out of the cells or mixing. The cell structural portions of at least a pair of the honeycomb structures adjacent to each other among the honeycomb structures arranged serially are disposed with a gap, and the first fluid passing through the cells mixes together between end faces forming the gap.

摘要： A heat exchange member includes: a honeycomb structure including: an outer peripheral wall; an inner peripheral wall; and partition walls arranged between the outer peripheral wall and the inner peripheral wall, the partition walls defining a plurality of cells, each of the cells extending from a first end face to a second end face to form a flow path for a first fluid; and a covering member for covering an outer peripheral surface of the outer peripheral wall. In a cross section of the honeycomb structure orthogonal to a flow path direction for the first fluid, the partition walls extend in a radial direction. Each of the cells is formed from the outer peripheral wall, the inner peripheral wall, and the partition walls.

摘要： A heat exchanger includes: a hollow pillar shaped honeycomb structure, a first cylindrical member, a second cylindrical member, a cylindrical guide member, and an upstream cylindrical member. A communication port is provided between the downstream end portion of the guide member and the second cylindrical member or at the guide member. The second cylindrical member has a horn shape in which a diameter of the upstream end portion of the second cylindrical member is increased radially outward. The upstream cylindrical member has a flange portion, and a rising position of the flange portion is located on a more downstream side than the upstream end portion of the first cylindrical member.

摘要： A heat conduction member includes: a cylindrical ceramic body, a metal pipe on the outer periphery side of the cylindrical ceramic body, and an intermediate member held between the cylindrical ceramic body and the metal pipe. The cylindrical ceramic body has passages passing through from one end face to the other end face and allowing the first fluid to flow therethrough. The intermediate member is made of material having at least a part having a Young's modulus of 150 Gpa or less. The first fluid is allowed to flow through the inside of the cylindrical ceramic body while the second fluid having lower temperature than that of the first fluid is allowed to flow on the outer peripheral face side of the metal pipe to perform heat exchange between the first fluid and the second fluid.
