<P>PROBLEM TO BE SOLVED: To provide a compact heat exchange structure with high heat efficiency, which is suitable for temporary heating of various fluids. <P>SOLUTION: In the heat exchange structure comprising a honeycomb structure integrally formed including a number of vertical passages 12 divided by partition walls 11 and extended in parallel in one direction and a heating means for heating a fluid, part of the vertical passages is closed at one vertical passage-directional end surface 13 of the honeycomb structure, and a turning-round part 15 connecting each closed vertical passage with each non-closed vertical passage 12 to reverse the flowing direction of the fluid is formed at the other end surface thereof, and a cross passage is formed in each closed vertical passage, the cross passage intersecting the vertical passages across the partition walls to connect the vertical passages to a hole formed in at least one side of the outer wall of the heat exchange structure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
