CERAMIC FLOW PASSAGE BODY, AND HEAT EXCHANGER INCLUDING THE SAME
PROBLEM TO BE SOLVED: To provide a ceramic flow passage body which is hardly broken when handled and has excellent joint strength and excellent durability, and to provide a heat exchanger including the ceramic flow passage body.SOLUTION: The ceramic flow passage body is constituted so that a plurality of first members 2, each of which consists of a silicon carbide-based sintered compact and in each of which the space formed by connecting an introduction-side hole 14a to a discharge-side hole 14b is used as a first flow passage 8, a second member 3 for introducing a first fluid into the first member 2, and a third member 4 for discharging the first fluid flowing through the first member 2 are joined to one another by using a first joint layer 16 containing silicon carbide and metallic silicon and a spacer 6 consisting of the silicon carbide-based sintered compact is joined to the first member 2 by using a second joint layer 17, which contains silicon carbide and metallic silicon and has the metallic silicon content higher than that of the first joint layer 16 between the adjacent first members 2.SELECTED DRAWING: Figure 1
【課題】取り扱い時に破損しにくく、優れた接合強度と優れた耐久性を有するセラミック流路体と、このセラミック流路体を備える熱交換器とを提供する。【解決手段】炭化珪素質焼結体からなり、導入側孔14ａおよび排出側孔14ｂを繋ぐ空間が第１流路８とされた複数個の第１部材２と、第１の流体８を第１部材２に導入するための第２部材３と、第１部材２を流れた第１の流体を排出するための第３部材４とが、炭化珪素および金属珪素を含む第１接合層16により接合され、第１部材２同士の間において、炭化珪素および金属珪素を含み、第１接合層16よりも金属珪素の含有量の多い第２接合層17により、炭化珪素質焼結体からなるスペーサ６が第１部材２に接合されているセラミック流路体である。【選択図】 図１
