PROBLEM TO BE SOLVED: To provide a heat exchanger allowing a fluid of high pressure to flow inside flat hollow bodies. SOLUTION: This heat exchanger is provided with the plurality of flat hollow bodies 2 arranged in parallel with a vertical-directional space, and extended in the lateral direction, a communication part 3 arranged between fellow left end parts of the vertically adjacent flat hollow bodies 2, and a spacer 4 arranged between fellow right end parts of the adjacent flat hollow bodies 2. Each flat hollow body 2 comprises top and bottom walls 11, a peripheral wall 12 astride between the top and bottom walls 11, and a partitioning wall 15 for partitioning an inside into two linear flow passages 13, 14 extended laterally. Through holes 16, 17 are formed to communicate longitudinal both side portions in left end parts of the top and bottom walls 11 with the communication part 3. A right end part of the partitioning wall 15 is cut out to communicate the two linear flow passages 13, 14 with each other. A through hole 36 is formed to be extended longitudinally in the spacer 4. The spacer 4 is arranged in a position corresponding to a cut-out part of the partitioning wall 15 in the each flat hollow body 2. COPYRIGHT: (C)2005,JPO&NCIPI
