<P>PROBLEM TO BE SOLVED: To provide a compact heat exchange structure which is high in heat efficiency and is suited for temporarily heating various fluids. <P>SOLUTION: This heat exchange structure is provided with: integrally formed honeycomb structure having a lot of vertical flow passages partitioned by bulkheads and extended in one direction in parallel; and a heating means heating fluid. A turn-around part is provided at least at one end part of the vertical flow passages for turning around the fluid flow. Multiple transverse flow passages are provided crossing the vertical flow passages and connecting the vertical flow passages penetrating through the bulkheads, in respective upstream side vertical flow passages and downstream side vertical flow passages, via the turn-around part. The multiple upstream side transverse flow passages are connected to holes formed on one outer wall face of the heat exchange structure, and the multiple downstream side transverse flow passages are connected to holes formed on an outer wall face different from the outer wall face. <P>COPYRIGHT: (C)2007,JPO&INPIT |
